Day 107 of Becoming a SOC Analyst — SOC337 Lazarus Phishing Campaign Detected APT38 (True Positive)
A phishing email with subject "Invitation Coinbase Crypto Trader Hiring Assessment" was delivered to Ellen at letsdefend.io, containing a malicious link to blockchainjobhub.com — confirmed crypto phishing infrastructure. Logs confirm the user clicked the link, triggering curl.exe spawned from explorer.exe (EventID 4688) to download nvidiaupdate.zip from api.drivercams.cloud and a secondary S3 staging source, followed by PowerShell extraction and registry query reconnaissance — a textbook Lazarus APT38 initial access and staging sequence. Endpoint was contained before lateral movement.
