From IcedID to Dagon Locker Ransomware in 29 Days
- In late August 2023, we observed an intrusion that started with a phishing campaign using PrometheusTDS to distribute IcedID. IcedID dropped and executed a Cobalt Strike beacon, which was then used through-out the intrusion. The threat actor leveraged a bespoke PowerShell tool known as AWScollector to facilitate a range of malicious activities including discovery, lateral movement, data exfiltration, and ransomware deployment. Group Policy was used to distribute Cobalt Strike beacons at login to a specific privileged user group. The threat actor utilized a suite of tools to support their activities, deploying Rclone, Netscan, Nbtscan, AnyDesk, Seatbelt, Sharefinder, and AdFind. * This case had a TTR (time to ransomware) of 29 days.

The LockBit’s Attempt to Stay Relevant, Its Imposters and New Opportunistic Ransomware Groups
The Trellix Advanced Research Center has recently observed an uptick of LockBit-related cyber activity surrounding vulnerabilities in ScreenConnect. This surge suggests that despite the Law Enforcement's (LE) "Operation Cronos" aimed at dismantling LockBit's infrastructure, the ransomware operators somehow managed to survive and stay a float. It appears that the cybercriminals group behind LockBit ransomware partially restored their infrastructure and created an impression that the LE actions did not affect their normal operation. Concurrently, alongside the resurgence of LockBit's exploitation of ScreenConnect vulnerabilities, we have seen other threat actors have either impersonated LockBit ransomware or incorporated LockBit into their own cyber attack campaigns.
Advanced Cyber Threats Impact Even the Most Prepared
