What happened
Recorded Future's Insikt Group attributes a new Windows batch-script backdoor called HOOKEDGE to APT28 (aka BlueDelta/Fancy Bear), deployed against government and diplomatic organizations in Romania, Spain, and Türkiye between late September 2025 and early April 2026. HOOKEDGE is delivered via macro-enabled Word documents with diplomatic-themed lures, uses webhook.site for C2 and exfiltration, and is described as a direct evolutionary successor to the earlier HEADLACE backdoor, with significant code and tradecraft overlap.
Why it matters
This is nation-state espionage targeting European diplomats via spear-phishing Word macros — it does not directly affect Malaysian builders or typical SaaS/agent tooling. The only broadly useful takeaway is that webhook.site's free-tier API limits forced the operators to adapt their C2, which is a reminder that abusing legitimate services for C2 remains common and hard to detect on network traffic alone.
Discussion angle
How attackers abuse legitimate services like webhook.site for C2 to blend into normal traffic, and what that means for defenders who rely on egress filtering or allow-listing popular developer tools.
