The Americans have released joint Cybersecurity Advisory (CISA, FBI, HHS, MS-ISAC) against the Black Basta ransomware. It is alleged that as of May 2024, more than 500 organizations worldwide have been affected by Black Basta, including businesses and critical infrastructure in North America, Australia and Europe. 12 of 16 critical infrastructure sectors are affected.
The ransomware was first spotted in April 2022. Initial Access is obtained through phishing or exploitation of the February vulnerability AuthBypass in ConnectWise ScreenConnect (CVE-2024-1709).
Privilege Escalation and Lateral Movement Toolkit: Mimikatz and Vulnerability Exploitation ZeroLogon (CVE-2020-1472), NoPac (CVE-2021-42278, CVE-2021-42287), PrintNightmare (CVE-2021-34527). Patches have been available for years, but organizations have not installed them. 🤷♂️ Perhaps they hoped that the perimeter would never be breached. 😏
