It is designed to evade detection using obfuscation and anti-analysis techniques while exfiltrating sensitive user data to a Command & Control (C2) server. Key Indicators of Compromise (IoC) Suspicious Behavioral Traits:

Self-Injection: Creates processes in suspended mode to inject malicious code.

Data Theft: Targets browser history, stored passwords, and cryptocurrency wallet data. bltools v2.2

Evasion: Detects if it is running in a virtual machine or sandbox and remains idle to avoid triggering alerts. Network Activity: Initiates connections to non-standard ports.

Connects to IP addresses known for hosting other malware variants. System Integrity: Uses invalid or forged certificates to appear legitimate.

Modifies system policies and registry keys to maintain persistence on the host. 🛠️ Technical Details Version Analyzed: v2

Compilation: Typically built using the .NET framework or Borland Delphi.

Persistence: Often drops additional executables into temporary directories to ensure the malware restarts upon system reboot.

5. File Formats & Metadata

  • Inputs: FASTQ(.gz), SAM/BAM/CRAM, VCF/BCF, reference FASTA (indexed).
  • Outputs: SAM/BAM/CRAM, VCF/BCF, gzipped FASTQ, JSON/TSV reports.
  • Provenance headers: each output contains a JSON provenance record (tool name, version 2.2, command-line, timestamp, git-hash) embedded in SAM/VCF header lines.
  • Checksum generation: optional block-level checksums for large outputs for integrity verification.

Tip 3: Docker Integration

For reproducible pipelines, use the official bltools v2.2 container:

docker pull bltools/bltools:2.2
docker run --rm -v $(pwd):/data bltools/bltools:2.2 validate --input /data/file.csv

Step 3: Run the migration helper

bltools upgrade --from-version 2.1

This script checks your bltools.yaml for deprecated keys (e.g., threads is now parallel_threads) and suggests corrections.
