US midterm elections largely unaffected by “nuisance” cyberattacks

US cybersecurity officials are breathing a bit easier, as fears of widespread cyberattacks against government websites on voting day have been abated. A handful of local and state government websites were met with attacks that limited peoples’ ability to access polling location data, but no vote counts or election systems were affected. Most of the attacks, which Analyst Alexander Leslie of the cybersecurity firm Recorded Future referred to as “a minor nuisance,” have not yet been attributed. However, a pro-Russia group has taken credit for the DDoS attack carried out against the website of Mississippi’s secretary of state. Read more.

New Chrome browser botnet lurks within fake Adobe Flash Player updates

“Cloud9,” a newly discovered Chrome browser botnet, has been seen used in the wild stealing credentials and keystroke data while injecting malicious code and ads. It also has the capability to enlist a victim’s computer for use in DDoS attacks. The malicious extension is not being distributed through official channels, instead hiding inside websites that purport to push Adobe Flash Player updates.

Cloud9 is believed to have been developed by the Keksec malware group, and Google urges all users to always use the most current version of Chrome and using the browser’s Enhanced Protection options.

Hackers begin posting Medibank customer data after company refuses to pay ransom

The ransomware attack on Australia’s Medibank continues to make waves, as the hackers have begun dumping customer data onto the dark web. Medibank finds itself in a challenging position, as it has opted not to pay the hackers and is now faced with customer outrage as the threat actors drip stolen information online where it can be used to build future cyberattacks. The data, compiled into “naughty” and “nice” lists, has been appearing on a blog associated with the Russian hacking gang REvil.

Azov data wiper poses as ransomware, frames security researchers

A heavily distributed piece of malware called Azov Ransomware has been discovered to actually be a data wiper. Victims are presented with no ransom request upon the malware launching, instead presented with a document that tells them to contact a list of security researchers and blogs to recover their data. Azov destroys data in 666-bit increments and the damage is unrecoverable. Researchers are unclear as to why a threat actor would not only distribute such a malware but actually pay to have it done. One theory suggests that Azov is being used as a smokescreen to cover up or distract from other malicious activity. Read more.

Phishing scams targeting verified Twitter users spike amidst Elon Musk’s changing policies

As Twitter haphazardly rolls out new policies regarding the network’s verification process, criminals have seized the opportunity to launch phishing scams that target the owners of accounts that already have a blue checkmark. Emails are being sent that contain a link to a page that asks the users for their username and password. It then sends them a two-factor authentication link via SMS. The emails create a sense of urgency and tell the recipient that they need to comply or face account suspension. Read more.
