Russian APT28 Breaches NATO Naval Shipbuilder in NATO Country, Deploys New Reflective Loader
AI-summarised brief · reviewed before publication
A Russia‑linked state‑sponsored group identified as APT28 (also known as BlueDelta, Fancy Bear and Forest Blizzard) has been linked to cyber‑espionage attacks against two NATO member states. The Symantec Threat Hunter Team, tracking the activity under the name Swallowtail, reported the use of a backdoor called HOOKEDGE and a previously undocumented reflective loader named ld.exe. Victims included a law‑enforcement agency, a naval shipbuilder and a military‑aircraft‑engine manufacturer. In the shipbuilder breach, attackers returned to the compromised host for a week, stole credentials via two distinct methods, opened a persistent SSH tunnel and deployed the new loader, which decrypts and runs an encrypted payload in memory using a runtime key. The campaign shifted from webhook‑based command‑and‑control to a dedicated IP address for tasking and exfiltration. The most recent indicator was a Visual Basic Script launcher observed on 24 September 2026; the extent of data exfiltration remains unknown.
