Threat Hunting Content: Uncover Bladabindi Backdoor

Bladabindi backdoor has been known since at least 2013, its authors monitor cybersecurity trends and improve backdoor to prevent its detection: they recompile, refresh, and rehash it, so IOCs-based detection content is almost useless. In 2018, the Bladabindi backdoor became fileless and was used as a secondary payload delivered by njRAT / Njw0rm malware. The backdoor infects USB drives to spread across the attacked organizations. Adversaries use Bladabindi to steal sensitive data, download and execute additional tools, and collect credentials, it is also used as a backdoor and keylogger.

Ariel Millahuel created the Threat Hunting Sigma rule based on recent findings to spot characteristics of this malware and released it on Threat Detection Marketplace. https://tdm.socprime.com/tdm/info/3DBnUyJPThQ2/SCFEwHEBjwDfaYjKnj0I/?p=1

Ariel is one of the most active contributors to the Developer Program, who leads the top 10 content authors this month. In April, he published 50+ Sigma rules to detect APT groups’ activity and various malware used in recent attacks.
