GreyNoise Detects Active Exploitation of CVEs Mentioned in Black Basta’s Leaked Chat Logs

Ransomware group Black Basta’s chat logs were leaked, revealing 62 mentioned CVEs (Source: VulnCheck). GreyNoise identified 23 of these CVEs as actively exploited, with some targeted in the last 24 hours. Notably, CVE-2023-6875 is being exploited despite not appearing in CISA’s KEV catalog — reinforcing the need for real-time intelligence beyond static lists.
