SUMMARY: 10 alerts | 2 CRITICAL | 4 HIGH | 3 MEDIUM | 1 LOW Recommended Action: ISOLATE WS-FINANCE-14 immediately; preserve memory image
Based on the chronological progression of alerts 003 through 008, which of the following best classifies the adversary's overarching attack methodology?
A double-extortion ransomware campaign combining data theft with system encryption.
A destructive wiper attack designed to permanently erase shadow copies and system files.
A botnet infection utilizing the host primarily for distributed denial-of-service attacks.
An insider threat operation leveraging authorized access to modify registry persistence keys.
Explanation
The sequence of alerts demonstrates a multi-stage attack where the adversary first steals sensitive data (Alerts 003 and 004) and then encrypts the local files while demanding payment (Alerts 006 and 007). Classifying this requires synthesizing the exfiltration and encryption phases, which together define a double-extortion ransomware methodology.
