As geopolitical tensions rise and cyber capabilities evolve, 2025 is shaping up to be a defining year for nation-state threat actors. Advanced Persistent Threat (APT) groups are now more aggressive, using AI-assisted reconnaissance, supply-chain infiltration, zero-days, and stealthy long-term persistence. Whether you're a SOC analyst, CISO, or defender looking two steps ahead, knowing which APT groups are most active is critical.

Below are the Top 10 APT groups to watch in 2025, based on recent campaigns, toolset evolution, and global impact.

1. APT29 (Cozy Bear – Russia)

Still one of the most sophisticated espionage actors, APT29 continues its focus on diplomatic networks, cloud infrastructure, and MFA-bypass techniques. Increasing use of Azure AD abuse and OAuth token theft makes them extremely dangerous.

2. APT28 (Fancy Bear – Russia)

Highly active during global elections and military conflict. Expect more supply-chain poisoning, hack-and-leak ops, and attacks on media infrastructure in 2025.

3. Lazarus Group (North Korea)

One of the most financially motivated APTs. Lazarus will likely expand into AI-engineered phishing, crypto exchange breaches, and supply-chain compromise of financial software.

4. APT41 (China)

A dual espionage + financially motivated group known for exploiting zero-days at scale. Their targeting of telecom, energy, and managed service providers is expected to rise significantly.

5. Mustang Panda (China)

Specializes in political and NGO surveillance using custom RATs and USB-propagating malware. Highly adaptive; known for rapid malware updates to evade EDR.

6. APT10 (China – Stone Panda)

A consistent threat to global supply chains. APT10 is deeply embedded in managed service provider ecosystems and cloud-hosted enterprise environments. Expect heavier targeting of Western critical infrastructure.

7. Sandworm (Russia – GRU Unit 74455)

Responsible for major infrastructure attacks including power grid disruptions. With global conflict intensifying, Sandworm remains the biggest threat to industrial control systems (ICS).

8. Charming Kitten (Iran – APT35)

Masters of credential harvesting, social engineering, and phishing. They increasingly target researchers, journalists, and think tanks. AI-generated deepfake personas expected to rise.

9. OilRig (Iran – APT34)

Focuses heavily on Middle East critical sectors. Their new modular backdoors and DNS-based covert channels make detection hard. Will likely target energy and oil infrastructure more aggressively.

10. Scattered Spider (UNC3944 / Muddled Libra – USA/Global)

Not a traditional nation-state group, but their rapid growth and sophistication put them on the APT map. Known for SIM-swapping, call-center social engineering, and cloud persistence attacks on major enterprises.

Expect them to adopt more ransomware partnerships and identity-focused attacks in 2025.

Recommendations for Defenders in 2025

✔ 1. Prioritize Identity Security

Most APTs now target MFA, SSO, OAuth tokens, and cloud creds. Deploy phishing-resistant MFA + strict identity governance.

✔ 2. Move Toward Zero Trust

No implicit trust — verify every identity, session, device, and API.

✔ 3. Improve Detection for Living-Off-the-Land Attacks

Monitor PowerShell, WMI, registry, and scheduled task anomalies.

✔ 4. Segment Critical Infrastructure

ICS/OT networks must be fully isolated from corporate IT.

✔ 5. Reduce Attack Surface With Patch Discipline

APT groups abuse fresh zero-days quickly. Prioritize patching externally exposed services.

✔ 6. Strengthen Supply Chain Security

Evaluate vendors for insecure CI/CD pipelines, outdated libraries, and weak identity practices.

✔ 7. Build Threat Intelligence Into Daily Operations

Tie MITRE ATT&CK mapping into SIEM, SOAR, and hunting playbooks.
