Security News > 2023 > August > Cuba ransomware uses Veeam exploit against critical U.S. organizations

The Cuba ransomware gang was observed in attacks targeting critical infrastructure organizations in the United States and IT firms in Latin America, using a combination of old and new tools.
BlackBerry's Threat Research and Intelligence team, which spotted the latest campaign in early June 2023, reports that Cuba now leverages CVE-2023-27532 to steal credentials from configuration files.
Apart from the Veeam flaw that's relatively recent, Cuba also exploits CVE-2020-1472, a vulnerability in Microsoft's NetLogon protocol, which gives them privilege escalation against AD domain controllers.
BlackBerry underlines the clear financial motivation of the Cuba ransomware gang and mentions that the threat group is likely Russian, something that has been hypothesized by other cyber-intelligence reports in the past.
In conclusion, Cuba ransomware remains an active threat approximately four years into its existence, which isn't common in ransomware.
The inclusion of CVE-2023-27532 in Cuba's targeting scope makes the prompt installation of Veeam security updates extremely important and once again highlights the risk of delaying updates when publicly available PoC exploits are available.
