What is a social engineering hack?

social engineering hack

NetworkTigers discusses the dangers of a social engineering hack.

“Social engineering” is a term that is becoming increasingly common in descriptions of hacks, data breaches, and cyberattacks. 

The average person thinks of a cyberattack as a highly sophisticated, technical campaign by someone expertly skilled in coding and computer programming. This is true in some cases, especially regarding government-led cyber campaigns. However, most cybercriminals are not genius supervillains but opportunists with just enough know-how to achieve their goals.

This is where social engineering comes into play.

Social engineering explained

Social engineering is when a criminal manipulates a victim into handing over login credentials or other information that can be used to stage a cyberattack or steal data.

This can be done via text message, email, chat, or even a phone call. A criminal may also ask for the ability to use your computer remotely to provide tech support, only to install malware to commandeer your system otherwise. 

A common thread among all forms of social engineering is that it usually involves one-on-one interaction with someone trying to fool you. In this way, social engineering is more about hacking people than computers.

Why is social engineering effective?

Most people wouldn’t regard themselves as gullible or easily fooled. However, the effectiveness of social engineering techniques suggests otherwise.

Much of this comes down to targeting. From overworked desk clerks eager to make a good impression when someone alleges to be a superior reach out to them to older members of the workforce who may not be up to speed on cybersecurity best practices, criminals know how to spot an easy mark.

Social engineering often takes the form of a phishing campaign. If a criminal can successfully access someone else’s email account, they can reach out to their personal or business contacts with questions regarding sensitive data.

Noteworthy examples of social engineering hacks

Google and Facebook

This scam involved hackers posing as businesses that had previously worked with Google and Facebook. The criminals emailed invoices for services that the legitimate business had provided. However, the invoice payment link instead sent money directly to the hackers. Over two years, criminals stole more than $100 million from the two companies using this technique.

The US Democratic Party

In the lead-up to the 2016 presidential election, a Russian phishing attack levied against members of the US Democratic Party resulted in the leaking of personal emails. This campaign used nothing more sophisticated than fraudulent email warning recipients of unusual activity on their account that requested that they click a link to change their password. 

Axie Infinity 

In the largest crypto theft thus far, North Korea’s Lazarus hacker gang made off with $620 million after tricking Axie Infinity employees with fake job offers. The scam went so far as to put victims through multiple interviews before finally offering them a position with a generous compensation package described in a PDF. However, the file contained malware that gave criminals the access they needed to steal from the company.    

How to spot social engineering

Because no single technique is applied to all social engineering campaigns, it can be challenging to know when you are being targeted. However, there are some basic things to look out for:

  • Links. Watch out for messages that contain a link, as these can often land you on a malicious website or result in you downloading malware.
  • Videos or photos of you. Social engineering scams on social media often include a link with language that implies it will take you to an image or video of you that may be embarrassing or shocking.
  • Urgency. From emails that need immediate responses to emergency requests for login data, criminals know that urgency can cause people to set aside common sense instead of a quick response.
  • Sign-in requests. Some scams take the form of a message that appears to be from a legitimate source, such as Paypal. These emails may inform you that your account has been breached and that you need to enter your login credentials to change your password.
  • Notifications of purchases you didn’t make. Sometimes campaigns involve emails that inform you of a purchase you never made or tell you that something you didn’t buy has shipped.
  • Donation requests. Criminals may try to exploit your generosity by posing as a charity.
  • Atypical communication. Most of us know how our contacts communicate. If you receive a message from a company or trustworthy person that contains unusual typos or is otherwise contrary to what you have come to expect, it is likely a scam.
  • Too good to be true. Whether it’s a lucrative job offer or a contest you don’t recall entering, messages that seem too good to be true typically are.

How to prevent social engineering

  • Training. One of the most effective ways to keep hackers at bay is to stay privy to how they try to take advantage of people. Employees who receive and respond to high volumes of emails, phone calls, and other correspondences are on the front lines and need to be able to recognize a suspicious inquiry or message.
  • Think before you respond. Criminals love applying pressure on their victims because stress can make people throw caution to the wind. Slow down if you receive an urgent request or message before responding. Reach out to the sender using a different avenue to confirm that the message is legitimate.
  • Reject and report. Emails that purport to be from companies asking for your login credentials or passwords are scams. If you receive one, inform your superiors as well as the company that is being impersonated.
  • Filter spam. Spam blockers can do a decent job of stopping suspicious emails before they appear in your inbox. Make sure that you’re using one.
  • Secure your system. Preventing an attack from ever being mounted is best, but antivirus software should be installed across all devices on your network. If a bad link is clicked or a malicious attachment is downloaded, an updated and robust security system might be the safety net that prevents a breach.
  • Update your hardware. Network equipment with outdated firmware should be replaced if the firmware cannot be updated to manage today’s threats from taking hold. You can update your equipment with refurbished gear from a reputable dealer.

The Uber hack explained

Uber hack explained

NetworkTigers on how the Uber hack happened.

Rideshare giant Uber fell victim to a cyberattack allegedly carried out by a teenage hacker. How did this hack happen? What has the fallout been so far? Could it have been prevented?

How the Uber hack happened

On Thursday, September 15th, users of Uber’s internal Slack message board discovered a curious message from a mysterious poster called “NWave” that read, “I announce I am a hacker and Uber has suffered a data breach.” The individual then posted confidential company information they claimed to have accessed, followed by a hashtag that read “#uberunderpaisdrivers.”

Due to the bold nature of the post, Uber employees initially assumed that it was a prank of some kind. Some even went so far as to interact with the poster, replying to the message with memes or humorous quips.

Shortly after, Uber revealed in a tweet from their Uber Comms account that a legitimate breach had occurred and that they were “in touch with law enforcement and will post additional updates here as they become available.” The company’s Slack and other systems were taken down as Uber attempted to understand what had taken place fully.

For their part, the hacker claiming responsibility showed little restraint in communicating with security researchers, bragging about the breach and explaining how easy it had been for them to initiate.

According to a report from Wired that referenced the attacker’s conversation with security researcher Corben Leo, the hacker reports having “first gained access to company systems by targeting an individual employee and repeatedly sending them multifactor authentication login notifications. After over an hour, the attacker claims, they contacted the same target on WhatsApp, pretending to be an Uber IT person and saying that the MFA notifications would stop once the target approved the login.

Based on their claims, it would appear that social engineering allowed the hacker to infiltrate a targeted system not through elaborate code navigation but by convincing an employee to hand over access by posing as a trusted source. 

The technique used here is called an “MFA fatigue” attack. One can easily imagine the worker’s eagerness to end the persistent notification interruptions that disrupted their day.

The hacker’s conversations and shared screenshots reveal that they were able to dig deep into the company’s source code once initial access had been achieved.

Additionally, they commandeered Uber’s HackerOne account, where the company privately discloses the information for bug bounty hunters. These vulnerability correspondences are meant to be kept secret until the company issues a patch.

Before losing access, the attacker is believed to have downloaded this information, although Uber reports that any bugs within the system have already been fixed.

The Uber hack fallout thus far

In a tweet the following day, Uber provided the following updates:

  • We have no evidence that the incident involved access to sensitive user data (like trip history).
  • All our services, including Uber, Uber Eats, Uber Freight, and the Uber Driver app are operational.
  • As we shared yesterday, we have notified law enforcement.
  • Internal software tools we took down as a precaution yesterday morning are coming back online this morning.

However, researchers are skeptical of the company’s few official statements. 

Screenshots shared by the hacker lead some to believe that they gained access to OneLogin, which would allow them a look into every nook and cranny of Uber’s data, including the user data that the company claims was safe from the breach.

While initially the hacker did not appear to be financially motivated or connected with any malicious hacker gang or enterprise, Uber reported that they believe the individual is associated with the Lapsus$ hacker gang. However, they have not disclosed exactly how they have drawn that conclusion.

Lapsus$ has recently experienced a meteoric rise in notoriety due to the collective’s successful hacks and ransomware attacks against high-profile victims in the tech and gaming industries. The fact that most Lapsus$ members seem to be teenagers gives credence to the hacker’s claims, and the bold manner in which they announced their presence is also par for the course regarding the gang’s brand.

Regarding some of the hacker’s assertions, Uber believes that the individual purchased stolen login credentials from the dark web instead of relying exclusively on social engineering to conduct the breach.

Mere days after the Uber hack, an attacker alleging to be the same person using the name “teapotuberhacker” took credit for hacking Rockstar Games and leaking a tremendous amount of footage from the publisher’s upcoming entry into the Grand Theft Auto series. They claim to have also stolen the game’s source code and have expressed interest in holding the data for ransom.

The boldness of the two hacks, the targeted companies’ nature, and the attacks’ back-to-back nature fit in with previous patterns established by Lapsus$.

The timing couldn’t be worse for Uber. It takes place five years after the company had suffered an attack that saw them discreetly pay a hacker $100,000 to keep the breach a secret. Joe Sullivan, Uber’s former chief security officer, is currently on trial for criminal obstruction in that case.

Additionally, US lawmakers have been taking a hard look under the hood at big tech’s security policies. Elon Musk’s legal battle with Twitter, reinforced by a whistleblower’s statement, has again put Silicon Valley uncomfortably under the federal microscope.

However, the hack of Rockstar and the leaking of video related to one of the gaming industry’s most anticipated titles in nearly a decade will likely result in the attack on Uber fading from the public’s attention.

Could this hack have been prevented?

As with many recent attacks that relied heavily on phishing or social engineering tactics, the hacker may have been stopped in their tracks had the targeted employee not taken the bait and verified their attempts at authorizing their access. This reliance on human error has become a favored methodology for hackers, as even the tightest security is only as strong as peoples’ ability to keep login credentials private.

Hackers are acutely aware of this vulnerability. They know how to achieve success and that being given login credentials is the path of least resistance when mounting a successful attack.

Companies and organizations know this as well. However, it is impossible to completely prevent a breach that relies on trickery instead of brute force system penetration or the detectable insertion of malicious software.

Firewalls, antivirus, and antimalware programs are necessary lines of defense but do not affect someone who can simply walk through the front door. Even multi-factor authentication, a highly recommended security protocol, is obviously of limited usefulness against this strategy.

The most effective preventative measure for this type of hack is education. Employees need to know the telltale signs of a phishing scam when they encounter one.

Organizations need to put policies in place about verifying requests for sensitive data or login credentials. While many companies are loath to create additional hoops to jump through when it comes to seemingly mundane activity, the financial risk of a potentially devastating attack far outweighs the inconvenience of slightly slower response times.

While low-level workers tasked with high correspondence turnover are regularly targeted due to being on the front lines of email and message-based attacks, high-level employees are not immune.

From messages purported to originate from the IT department at Twilio to a fake job offered to a senior engineer at Axie Infinity, it would appear as though hackers have found the security Achilles heel that no amount of sophisticated coding or White Hat hacking can fully protect against.

Five must-subscribe-to security alert warning services

0
security alert services

NetworkTigers on security alert services.

Security alerts help with detecting advanced cyberattacks in organizations. Most of the time, your organizations IT team gets bombarded with security alerts from several IT devices in use. However, most of these alerts turn out to be false positives. The most challenging task for your IT team would be to figure out the normal behavior, the false positives, and what the actual threats are.

Your security team should focus on the right security alerts. Below are some must-have security alerts to subscribe to and begin sifting through the false alerts.

1. Privileged User and Account Monitoring

One of the biggest security weaknesses for an organization is its privileged user accounts. End users with endpoints can have root or administrator privileges, leading to malware infiltration. This can further lead to changes to system networks or settings or even letting bad actors or hackers access sensitive data.

Dashboards should be created to monitor privileged user activity. Since privileged accounts are entry points to other systems and applications in your network, hackers always attempt to obtain access to them and escalate privileges. With access to these accounts, there is potential to work through firewalls or the Intrusion Detection Systems (IDS).

2. Abnormal Outbound Activity

Inbound traffic is always monitored by the security teams but are the abnormal outbound activity monitored similarly? External network communication can occur through an abnormal port or protocol. A firewall can only work on traffic filtration and may not catch everything. These external communications may deploy malware, carry on command-and-control activities or conduct swarm and hive bot activities.

Your security team should deploy mechanisms to filter, monitor, and block external communication. External communication towards an open source is normal until the communication is not for public resources. This could mean that it is an unauthorized communication. Any suspicious activity should be checked against your security policy and malicious patterns. Security alerts can be made from your firewalls, IDS/IPS, and switches to monitor these outbound activities. The best tried and tested way to monitor is with a Security Information and Event Management or SIEM.

3. Acceptable Use Policy Violations

As part of the onboarding process, every employee should undergo a security briefing, an annual review, and a sign-off. Your employees usually sign acceptable use policies while they join, but their importance may be ignored without the briefing and frequent check-ins. These policies are security rules employees need to follow regarding organizational technologies. AUPs protect the company’s network and resources from bad actors but are often not monitored as intended.

Dashboards to review security alters need to be set up by security teams. Downloading torrent content, browsing through inappropriate content, or phishing scams are just a few instances where your company’s network is vulnerable to malicious activity. Frequent check-ins and alerts can help find endpoints with malware quickly and thus help mitigate risk factors,

4. Data Exfiltration

One of the main purposes behind advanced persistent threats (APTs) is data exfiltration or unusual port activity. Ports that are used frequently can be used to go past firewalls and IDS, leading stealing of company information. Phishing scams and social media can also be used to infiltrate your company’s network. Ports like TTCP: 80 (HTTP), TCP: 443 (HTTPS), TCP/UDP:53(DNS)

Techniques used by hackers to conduct an attack is as follows:

  • Web applications: Ports can be used to access your data directly by threat actors.
  • Backdoors: It can be used to collect files and use ports to hide traffic
  • File Transfer Protocol: Hackers may use FTP or FTPS for transferring files or may use a cloud provider
  • Windows Management Instrumentation:  This can be used to access files and mail accounts on Microsoft Outlook

Security alerts can be set up with network intrusion and prevention systems logs to identify any malicious activity mentioned above. Alerts may be set up to let your security teams know when data is being shared externally beyond recommended.  SIEM configurations that help identify what normal traffic looks like and send alerts when traffic goes beyond this baseline will also be helpful.

5. File Integrity Monitoring

File Integrity Monitoring (FIM) is a tool that needs to be looked into closely. Alerts and dashboards that show file status when unexpected changes are made need to be set up. File access auditing lets your team know if any files were created or deleted, programs being used to execute a file, and what file is being viewed. Any unusual files must be run through an anti-virus tool to identify the malware.

Five ways to ensure enterprise network security

enterprise network security

NetworkTigers provided five ways to ensure enterprise network security.

In 2022, businesses are facing cyberattacks more than any other previous year. An IBM report conducted in 2018 found that the average cost of data breaches globally rose to 6.4%, reaching $3.86 million. This means that network security must be a daily priority. Consider it a discussion point for every network meeting.

With the rising number of platforms, apps, and devices being used in the workplace, vulnerabilities to prepare for have increased significantly, making securing and monitoring all these devices difficult. How can you ensure enterprise network security to minimize cybersecurity threats? Keep reading to learn more.

How to make your enterprise network secure

Whether you’re in charge of the security of a big business network, run a small business, or work for yourself, you must implement some basic enterprise network security measures to defend against potential attacks.

Follow these simple steps to create a secure network:

Conduct a network audit

Before improving your network security, conduct an audit to know the current position of your business. This step is crucial because you can’t improve underperforming areas without identifying your weaknesses. 

The objective of performing a network security audit is to evaluate the following:

  • Unnecessary or unused apps running in the background
  • The overall health of apps, software, and computers
  • Anti-malware and anti-virus software
  • Potential security vulnerabilities
  • Backup schedule and history
  • Strength of your firewall

Keep in mind that the number of connected applications and devices running on your network plus the size of your company will determine the depth of your network security audit. 

Remember that an enterprise security audit is part of your overall cybersecurity policies and processes and focuses on the network itself.

Visitors or employees sharing sensitive data with hackers or walking out with information on memory sticks fall under cybersecurity, while network security covers what users do on the network itself.

You can use the findings of a network security audit to create a plan for enhancing the areas identified as weaknesses, either through third-party network security companies or internally. 

Update anti-malware or anti-virus software

It’s not enough to ensure that all the devices connected to your network have adequate protection from such software. 

Most organizations buy anti-malware and anti-virus software that they deploy at an enterprise level to ensure all employee devices, such as mobile phones or laptops, have this software installed when a new device is assigned to a staff member.

However, over time, the software becomes outdated, and in most cases, workers rarely update the software again, exposing your network to vulnerabilities each time they connect. 

Since outdated software/firmware is a common breach point for hackers, updating your anti-malware and anti-virus software is a priority and a part of an ongoing and regular schedule for updating all employee software on connected devices across your business network.

Invest in a Virtual Private Network (VPN)

A VPN ensures online privacy for all your employees as it encrypts your network. VPNs make your online actions virtually untraceable by masking your internet protocol (IP). 

VPN services create encrypted and secure connections to offer greater privacy than a secured WiFi hotspot. Additionally, they block your browsing history, personal information, data, communications, and activities from potential cyber attackers. 

A VPN is an important line of defense if your workforce works remotely and regularly connects to public WiFi networks in airports or cafes, as it protects files when using such networks.

Set up a network security maintenance system

Although your initial network security setup is important, it’s also crucial to establish a network security maintenance schedule that covers the following key actions:

  • Setting up a regular schedule for updating network passwords and names
  • Scheduling training on emerging security developments
  • Updating user passwords occasionally
  • Ensuring software is up to date
  • Creating regular activity reports
  • Conducting regular backups

These basic steps should be part of your “network security maintenance schedule.” Depending on the complexity and size of your business, you may need to include more elements in your schedule to stay on top of network security threats.

Stay proactive because network security is an ongoing process.

Install a firewall

Like VPNs, a firewall is essential for your business network. Keeping the firmware updated and the technology current is a daily check.

While a firewall can be set up on individual devices, your anti-malware or anti-virus software might include firewall protection. However, you can also install a firewall as a web application firewall (WAF) in addition to protecting individual devices.

A WAF protects web applications by monitoring and filtering HTTP traffic between the internet and a web application. Usually, a shield is placed between the internet and a web application when a WAF is deployed in front of web applications.

Proxy servers tend to protect the user’s machine’s identity using intermediaries. At the same time, a WAF is a reverse proxy that protects computers from exposure by requiring users to pass through the WAF before reaching the computers. 

Installing a WAF is crucial for online stores that keep customers’ sensitive data as it can protect all your stored information.

Conclusion

Most network security breaches happen due to insufficient processes and appropriate software. Every business, large or small, should invest in cybersecurity solutions such as SonicWALL or Palo Alto Firewalls to protect their network and devices from cyber threats.

Future of cybersecurity

NetworkTigers discusses the future of cybersecurity. Will it get worse before it gets better?

Cybersecurity is one of the most important investments any company or individual can make in today’s interconnected world. Ensuring that your home or business is appropriately protected can save more than money – it can also protect your privacy in an era where data privacy is becoming even more precious and important to preserve. However, today’s cybersecurity landscape is an ever-evolving field of threats and dangers. Will cybersecurity get worse before it gets better? Experts seem to believe that the risks will only continue to evolve. The question is, how can we best ensure we are prepared to meet them when they do?

With the rise of remote work and multiple supply chain shocks that overtook the international datasphere throughout the global pandemic, cybersecurity was paramount in 2020. The COVID-19 era saw multiple new threat actors arise in how companies conducted remote work. Zoom bombers, new kinds of ransomware, and a rise in phishing attacks on employees working from home all contributed to increased cybersecurity risks in the past year. However, a new report shows an alarming trend in how often businesses have been hacked throughout 2021. According to Check Point Research, businesses weathered up to 50% more cyberattacks per week in 2021 than in 2020. The analytical firm only counted detected and blocked threats in their assessment, meaning that the actual number may be even higher. With numbers like these, it’s no wonder that businesses seem to have begun to accept cyberattacks as the new normal

Cyber threats on the rise

The data shows that cybersecurity seems to be getting worse before it gets better. Some of the latest cyber threats include: 

  • Social engineering: Even as technology becomes more difficult to breach, human error remains the main form of cybersecurity weakness. Social engineering is a kind of attack method that targets human interactions. Socially engineered attacks often rely on peoples’ urges to be helpful or fear of punishment if they make a mistake. Many data security experts advocate for increased employee IT training and open communication among company strata to address socially engineered cybersecurity threats. Employees are less likely to believe they risk letting down a CEO or senior officer from a phony phishing attack if they can contact management to report attempts to target them. 
  • Sophisticated phishing: Phishing is particularly dangerous for employees working from home. As more business communication occurs via email or messaging, phishing attempts have become more prevalent and successful. In a recent development, certain industries, often medical and insurance, report facing a one-two punch of phishing attacks. Employees in these fields have received emails from realistic addresses posing as clients or vendors for the company. The only request in these emails is that the targeted employee give them a call. Scammers use these sophisticated phishing approaches to build rapport and trust before asking the targets to share information or send money. Because multiple forms of communication are used, these phishing attempts appear more trustworthy. A San Francisco report shows a 10% increase in email-to-phone phishing attacks, with businesses in the medical and insurance fields up to 60% likely to become targets. 
  • Credential compromise: The reuse of passwords is a common threat to even the best cybersecurity networks. Even with constant verifications or multi-factor authentication, re-used or commonly used passwords can undermine otherwise effective barriers to keep hackers at bay. A Google study shows that up to 65% of people reuse their passwords for multiple accounts. Much of this password reuse is across streaming sites, but many report mingling personal and professional passwords. Some recycling is understandable when the average person has to remember around 90 different passwords. However, doing so can substantially jeopardize the safety and security of your company’s network privacy. 

Cybersecurity reports and assessments

Will cybersecurity get worse before it gets better? Even the most optimistic data privacy experts say things will get more complicated before anyone can be sure. And most cybersecurity professionals say the outcome is bleak. Cybersecurity has gone from being a small-scale concern to a full-blown national and international security risk. Destructive hacks such as SolarWinds show that the extent of data privacy breaches is still fully understood. 
Ongoing hacks threaten the safety of every Internet user, with new risks being discovered daily. By updating and investing in cybersecurity to the fullest extent of your ability, you can hope to surf the wave of new worries in the cybersecurity sector. However, no one can fully outrun the onslaught of cyber risks. It’s going to get a lot worse before it gets better, but with the right focus and upgrades, we can weather the storm.

Scammers and hackers: what’s the difference?

Scammers and hackers

NetworkTigers discusses the difference between scammers and hackers.

When it comes to cybersecurity threats, the terms “hacker” and “scammer” are used regularly. To some, the words may seem interchangeable and, in fact, hackers and scammers often overlap in the methods they use to meet their goals. However, there are differences between the two that define them as separate threats.

What is a hacker?

A hacker is an individual who uses a computer to overcome a technical problem or obstacle. The term, coined in the 1960s, is used to refer to someone especially savvy with coding and programming as well as to describe one who uses said skills for criminal activity. 

While there are ethical, “white hat” hackers who are employed to work against criminals, most people associate the word with “black hat” hackers who steal data or commit otherwise unscrupulous deeds.

What hackers do

  • Create, deploy or install malicious code that is designed to penetrate victim networks.
  • Exploit vulnerabilities within systems to gain unauthorized access.
  • Vandalize targeted websites or social media accounts for reasons that range from political motivation to bragging rights.
  • Engage in corporate or political espionage by stealing data from competing companies or nations.
  • Employ ransomware in order to encrypt a victim’s network and extort them.
  • Break into systems to cause disruption.

What motivates hackers?

Because there are so many different kinds of hackers working from all over the world, their motivations vary greatly.

Hackers employed by governments, whether transparently or in secret, typically target websites or systems used by organizations associated with opposing countries. This can include those belonging to third-party contractors and other agencies who may be in possession of, or have access to, government information that is deemed to be valuable for purposes of sabotage or espionage.

In cases like North Korea, state-backed hackers are even used to hack into financial institutions or cryptocurrency exchanges to provide a source of revenue for the country.

Some hackers are motivated by social issues or work independently to bring attention to their causes and inflict damage on organizations and even governments that they disagree with politically. The hacking collective Anonymous is best known for performing this type of “hacktivism.”

Many other hackers are after money. Whether it’s through a ransom or by selling stolen data on the black market, information is valuable to those who wish to do harm to others.

What is a scammer?

A scammer, defined broadly, is a person who participates in a fraudulent scheme or operation.

In the context of cybersecurity, scammers use a variety of means to steal money or information from victims. While there are hackers on both sides of the law, scammers are, by definition, malicious.

What scammers do

  • Employ social engineering tactics to fool people into turning over sensitive information such as login credentials.
  • Engage in phishing schemes that impersonate trusted companies, organizations or even individuals to convince people to provide everything from financial data to personal information that can be sold.
  • Scammers sometimes study victims in order to create convincing fake correspondences or scenarios that encourage trust.
  • Blast out hundreds or thousands of emails or texts, hoping to play the numbers game and rope in unsuspecting or accidental victims.
  • Create “romance scams” in which they adopt a fake identity to gain someone’s affection and then ask for money. 

What motivates scammers?

Whereas hackers may be motivated by politics or social justice, scammers are exclusively interested in financial gain. This can be in the form of funds directly siphoned from a targeted victim or money exchanged for stolen data.

From shooting out hundreds of emails that mimic the look and branding of trusted institutions like banks or PayPal to engaging directly with their victims by impersonating a love interest or fellow employee, there are a myriad of ways that scammers can successfully part a target from their money. 

While most people can’t conceive of engaging in such unethical behavior, psychologists generally regard scammers and con artists as narcissists. Only interested in their own personal gain, they lack empathy and view themselves as superior to those who are foolish enough to fall for their tricks. 

The internet age puts new tools and more anonymity into the hands of scammers, but this behavior is not new. From tricking sailors into believing they were destined for a paradise of riches in the 1820s only to have them find themselves in Honduras to selling city monuments to people eager to make big investments, scammers have been preying on the trust of others for centuries.

How to avoid scammers and hackers

To prevent hacks, it’s important to ensure that your fortifications are strong. Be sure to keep your software and firmware regularly updated. Setting up automatic updates lets you keep your systems refreshed without the risk or forgetting to do so. They also let developers patch their products in the event of a newly discovered threat or vulnerability.

The best policy one can have with regard to scammers and hackers alike is one of vigilance. The confidence that most people have regarding how easily they may be fooled is often turned against them. Because no one believes in their own gullibility, con artists and criminals are able to manipulate people surprisingly easily.

Tips to avoid becoming a victim

  • Check for misspellings and typos in emails from supposedly trusted organizations or companies that have a sense of urgency or remind you of a purchase you don’t recall making.
  • Check the email address of origin for messages you receive. If the address is not one you recognize or contains misspellings or other suspicious characteristics, it is likely a scam. 
  • Never provide login information, personal data or financial information to someone over the phone or via email or text.
  • Stick to official platforms for communicating with colleagues at work. Scammers may attempt to impersonate an employee in need of help via messaging services that operate outside of your business.
  • If you receive a message from someone you trust that feels off, find another way to reach out to them to confirm that it’s legitimate.
  • Never send money to someone that you haven’t met. 
  • Keep up to date on the latest cybersecurity threats by regularly checking websites that feature news regarding today’s trends.

Ransomware attacks rebound after a brief decline.

A report released by NCC Group reveals that ransomware attacks are on the rise again after a short decline. It is believed that the ebb and flow is related to the US government’s crackdown on cybercrime and the Conti ransomware gang. It would seem that the regression took place as ransomware purveyors reevaluated their tactics and regrouped in the face of increased pressure. LockBit has proven to be the most prevalent gang in this new surge, with HiveLeaks and BlackBasta, both offshoots of Conti, also hard at work. Read more.
