Jasper the unfriendly loader

The Stairwell threat research team recently assisted our partner Solis Security with the analysis of JasPer Loader, a trojanized Dynamic Link Library (DLL) file that mimics legitimate software, offering attackers a gateway to load additional malware into a target network.

In the threat report linked below, the cyber threat intelligence team at Solis delves deep into the loader’s technical details, how it works, and detection and mitigation strategies – including a YARA rule by the Stairwell threat research team and a SentinelOne Active Response (STAR) rule.

We believe that as a community, we’re better together. That’s why we are proud to have worked alongside Solis and SentinelOne in the analysis and mitigation of JasPer Loader. We encourage you to download the full report by Solis linked below to gain a deeper understanding of JasPer Loader and how to protect against it.
