In Part 3 of our series on emulating, debugging and fuzzing UEFI modules, we provide a step-by-step guide to making a coverage-guided fuzzer for UEFI code.
The team behind Trickbot has been aggressively updating and deploying various modules including Anchor and Bazar Loader targeting high-value targets, including healthcare entities
The ability to remotely debug an application is a useful feature, but msvsmon.exe has security implications that organizations need to be aware of.
Ryuk’s success is based partly on leveraging other toolkits and vulns, partly on its encryption speed and evasion tricks. We tear it down for a closer look.
New research shows that the Purple Fox exploit kit has added new tricks to its attack flow and continues to target vulnerable versions of Internet Explorer.
Abusing LD_PRELOAD to intercept library calls on Linux is a known threat actor technique, but it’s possible to load libaries even before that. Meet LD_AUDIT
Learn how to emulate, trace, debug, and Reverse Engineer UEFI modules in part 2 of our new blog series on Firmware Security
FONIX RaaS uses four methods of encryption per file and leads victims (and affiliates) on a merry dance through multiple emails to obtain decryption.
At Sentinel Labs, we have been closely tracking adversarial behavior as it pertains to COVID-19/Coronavirus. To date, we have observed a significant number of malware campaigns, spam campaigns, and outright…
Raas (Ransomware-as-a-Service) continues to fuel the cybercrime economy. SMAUG offers Windows, Linux and macOS support among other unique features.
