A phishing email with a password-protected ZIP delivered AsyncRAT via a SILENTBUILDER dropper. The victim executed the payload, establishing an active C2 channel and triggering full host reconnaissance before containment.

User Tony downloaded and executed a malicious PowerShell script (payload_1.ps1 / agent3.ps1) classified as trojan.powershell/boxter (Azorult family). The script bypassed execution policy, then fetched and invoked a second-stage payload from kionagranada.com (161.22.46.148), establishing a two-stage C2 chain with a final pivot to 91.236.116.163.

Three phishing campaigns were identified across four alerts: a legitimate HR onboarding email (false positive), a fake Amazon delivery notification whose bit.ly link was blocked by the firewall, and a Microsoft account spoofing email from m1crosoftsupport.co whose link was allowed through the firewall

Detected a SQL Injection attack, observed 85 alerts across 6 rule IDs, and configured automated IP blocking via active response.

Replayed a malicious PCAP file containing Hancitor dropper traffic that deployed Cobalt Strike, Dridex, and Ficker Stealer. Analyzed 423 Suricata alerts in Wazuh, reconstructed the full infection chain, and mapped findings to MITRE ATT&CK.

Simulated an SSH brute force attack using Hydra, observed Wazuh detection across 7 rule IDs, identified a gap in default alerting (max level 10), wrote a custom rule to escalate severity to level 12, and configured automated IP blocking via active response.
