What defenders are learning from Black Basta’s leaked chat logs

Leaked internal chat logs from the Black Basta ransomware group reveal nearly 200,000 messages containing IOCs (IPs, domains, credentials, filenames), descriptions of custom malware loaders and TTPs, and insights into the group’s structure and operations; researchers and defenders are using this intelligence to support hunting and attribution, while the leak has destabilized the group amid prior defections and periods of reduced activity.
