Threat Analysis

This YARA rule is designed to detect general threats.

Severity Level: Medium

The rule uses pattern matching to identify specific byte sequences, strings, or behavioral patterns associated with malicious activity.

Detection Capabilities

  • File-based detection for executables and documents
  • Memory scanning for running processes
  • Network traffic analysis support

Command Line Usage

# Scan a single file
yara Antivirus_Signature.yar /path/to/suspicious/file

# Scan a directory recursively
yara -r Antivirus_Signature.yar /path/to/directory/

# Scan with metadata output
yara -m Antivirus_Signature.yar target_file

# Scan process memory (Linux)
yara Antivirus_Signature.yar /proc/[pid]/exe

Integration Examples

Python (yara-python)

import yara
rules = yara.compile(filepath='Antivirus_Signature.yar')
matches = rules.match('/path/to/file')

ClamAV Integration

clamscan --yara-rules=Antivirus_Signature.yar /path/to/scan
