Ransomware gangs continue to hammer local governments in attacks, taking down IT systems and disrupting city's online services.
Earlier this month, we saw that with the Royal Ransomware attack on Dallas, and this week the City of Augusta, Georgia, is also suffering a cyberattack.
While the Augusta mayor's office has disclosed a statement stating that they suffered a cyberattack, they did not share any details on the breach.
"The City of Augusta, GA began experiencing technical difficulties this past Sunday, May 21, 2023, unrelated to last week's outage, resulting in a disruption to certain computer systems," reads the City's statement.
"We began an investigation and determined that we were the victim of unauthorized access to our system."
However, today, the BlackByte ransomware operation claimed responsibility for the attack on Augusta, leaking data that they claim was stolen during the attack.
Other attacks we learned more about this week include a BlackBasta attack on German arms manufacturer Rheinmetall and ABB confirming data was stolen during an attack earlier this month.
The Cuba ransomware gang also claimed the attack on The Philadelphia Inquirer. However, after the publisher stated the data did not belong to them, Cuba took the Inquirer's entry from their data leak site.
We also saw some interesting reports released by security firms and researchers:The ALPHV/BlackCat ransomware gang is now using the malicious POORTRY Windows kernel driver. Iranian hackers have created a new Moneybird ransomware to attack Israeli orgs A new Buhti ransomware operation is using the leaked LockBit and Babuk encryptors.
Finally, ransomware affiliate Bassterlord released a "slightly" edited but highly sought-after version of his ransomware manual version 2.0 that was being sold for $10,000 on hacker forums.
While some researchers felt the manual lacked detail, threat actors can still use it to gain more knowledge and learn how to breach corporate networks.
While we are not sharing this manual, it is advised that all network defenders and security professionals read the translated versions floating around on Twitter, or some of the linked analyses below, to learn what tactics were being taught.

Yesterday Basterlord (an infamous ransomware operator) published a copy of “Networking Manual v2.0” (which I’ll refer to as “the manual”). So I of course thought we should analyze this and look to see what he was selling for $10 thousand dollars!
