SentinelOne Demo: SentinelOne VS U-Bomb Ransomware – Detection and Mitigation

In this video demonstration, see how the SentinelOne Singularity XDR Platform detects and mitigates U-Bomb ransomware, also known as 0xFFF.

Active since at least March 2023, this semi-private ransomware operation targets a smaller pool of victims compared to larger operations such as LockBit. U-Bomb also shares some visual similarities with Hive (Hunters International). However, verifiable links between the two operations beyond those that are visual only or surface level have yet to be corroborated.

U-Bomb targets large enterprises and small to medium-sized businesses (SMBs), though there does not appear to be any specific discrimination when it comes to industry or type of target.

While U-Bomb ransomware payloads are historically delivered via phishing email, campaigns have been observed as the result of exploitation of exposed and vulnerable services, as well as via third-party offensive frameworks (i.e., BRC4, Sliver, Cobalt Strike.) U-Bomb payloads exist for both Windows and Linux. As of November of 2023, operations are focused on Linux.

The SentinelOne Singularity XDR Platform can identify and stop any malicious activities and items related to U-Bomb ransomware.
