Symantec Links APT28 to Espionage Campaign Against NATO Defense Firms and Police Agency

· Original article ↗

Summary

Symantec says APT28 compromised two defense firms and a law enforcement agency in NATO countries. The campaign used the Hookedge backdoor and an undocumented loader; researchers did not recover the loader’s payload.

Key points

  • Symantec attributed the campaign to Swallowtail, also known as APT28, Fancy Bear and Forest Blizzard, which it linked to Russia’s GRU.
  • Targets included a naval shipbuilder, a military aircraft-engine maker and a law enforcement agency in NATO countries.
  • At the shipbuilder, attackers repeatedly accessed a compromised host over a week and stole credentialed material, according to Symantec.
  • The hackers used the Hookedge backdoor; Recorded Future had previously observed the group using it against defense and diplomatic targets in Romania, Spain and Turkey.
  • Symantec also observed an undocumented loader that decrypts its payload in memory and requires a runtime command-line key. Researchers did not recover the payload, so its function is unknown.
  • A Symantec analyst said the campaign’s motive was uncertain and speculated it could involve targeting countries aiding Ukraine.
