Nation-state hackers (APTs)

Patient, well-funded and usually after secrets, not ransom.

What it is

Advanced Persistent Threats (APTs) are hacking groups backed by governments. They spy, steal intellectual property, pre-position inside critical infrastructure and sometimes sabotage. Security companies give them names (Fancy Bear, Lazarus, Volt Typhoon) and track their tactics. Many 'live off the land', using built-in admin tools so they blend in with normal activity.

Real case · 2020

SolarWinds

Russian intelligence hackers slipped a backdoor into updates for SolarWinds Orion, network software used by about 18,000 organisations, then picked high-value targets including US government agencies.

How defenders stop it

  • Map defences to attacker behaviour using MITRE ATT&CK
  • Log and review use of admin tools like PowerShell
  • Segment networks so one foothold doesn't reach everything
  • Threat hunting: assume breach and look for it

1. What does 'living off the land' mean?

  1. Hacking from a rural location
  2. Using a system's own legitimate tools to avoid detection
  3. Stealing farming data
  4. Only attacking physical infrastructure

2. What does APT stand for?

  1. Automated Phishing Tool
  2. Anti-Piracy Team
  3. Applied Penetration Test
  4. Advanced Persistent Threat

3. Which framework maps attacker tactics so defenders can check what they'd detect?

  2. CVSS
  3. GDPR
  4. TLS
