Query Breakdown: The query uses the content modifier to search for a specific hexadecimal string within the file's binary data, acting as a precise digital fingerprint for this specific malware strain.
Summary of Intent: The overall goal of this search is to rapidly and precisely identify active LockBit 3.0 samples targeting Linux/UNIX environments.
The search looks for:
- Target: LockBit 3.0 ELF ransomware (often used against ESXi servers and Linux infrastructure).
- Mechanism: It relies on content matching rather than metadata or behavioral reports.
- Precision: By using a long, distinct byte signature, it enables high-confidence detection for immediate blocking of new or active samples.
