Axios NPM Compromise Indicators - Linux
#Detects the Linux-specific execution chain of the plain-crypto-js malicious npm dependency by Axios NPM package, including payload download via curl and detached execution using nohup and python3. On March 30, 2026, malicious versions (1.14.1, 0.30.4) were published to npm, injecting a dependency (plain-crypto-js@4.2.1) that executed a postinstall script as a cross-platform RAT dropper. The dropper contacted a C2 server, delivered platform-specific payloads, deleted itself, and replaced package.json to evade detection.

BaaUpdate.exe Suspicious DLL Load
#Detects BitLocker Access Agent Update Utility (baaupdate.exe) loading DLLs from suspicious locations that are publicly writable which could indicate an attempt to lateral movement via BitLocker DCOM & COM Hijacking. This technique abuses COM Classes configured as INTERACTIVE USER to spawn processes in the context of the logged-on user's session. Specifically, it targets the BDEUILauncher Class (CLSID ab93b6f1-be76-4185-a488-a9001b105b94) which can launch BaaUpdate.exe, which is vulnerable to COM Hijacking when started with input parameters. This allows attackers to execute code in the user's context without needing to steal credentials or use additional techniques to compromise the account.

Change Default File Association To Executable Via Assoc
#Detects when a program changes the default file association of any extension to an executable. When a file is opened, the default program used to open the file (also called the file association or handler) is checked. File association selections are stored in the Windows Registry and can be edited by users, administrators, or programs that have Registry access or by administrators using the built-in assoc utility. Applications can modify the file association for a given file extension to call an arbitrary program when a file with the given extension is opened.
