Arctic Wolf Reverses CyberStrike Harvester Behind FortiBleed  

Arctic Wolf reverse engineered the CyberStrike Harvester behind the FortiBleed campaign, which targets Fortinet FortiGate devices through credential theft rather than malware. 

The CyberStrike Harvester automates credential extraction and validation, enabling attackers to access VPNs, enumerate Active Directory, browse SMB file shares, and steal enterprise data.

This campaign reportedly affects tens of thousands of FortiGate devices across 194 countries and remains active in the wild. 

Rotate credentials, continuously monitor, and test incident response plans with scenarios around credential compromise and identity attack paths.

Operation Endgame Cripples StealC 

An international law enforcement operation disrupted the StealC malware ecosystem, seizing more than 25.6 million stolen credentials. 

StealC is a malware-as-a-service infostealer that steals credentials and other data used in ransomware and account takeover attacks. 

Europol, Microsoft, Proofpoint, IBM X-Force, and other partners supported the investigation, including the discovery of a flaw in the StealC C2 panel.  

Search your environment for compromised credentials, force password resets for exposed accounts, and require phishing-resistant MFA.

Kitana Powers AI-Driven Fraud 

AI is helping cybercriminals build more sophisticated fraud platforms that steal credentials and payment data during live online sessions. 

NCC Group found that Kitana combines phishing, reverse proxy infrastructure, and real-time attacker interaction to steal credentials, authentication codes, and payment data. 

Researchers also identified evidence of AI-assisted development, highlighting how AI is accelerating cybercrime. 

Monitor certificate transparency logs and newly registered typosquatted domains, and alert users to verify website URLs before entering credentials or approving unexpected authentication prompts.

Threat Tracker

Five Eyes Sounds AI Alarm 

Artificial intelligence is expected to accelerate cyberattacks within months, according to a new warning from the Five Eyes intelligence alliance. 

The alliance warned that AI is accelerating cyberattacks by shortening the time between vulnerability discovery and exploitation while enabling more convincing phishing and prompt injection attacks.

As AI adoption grows, organizations should strengthen access controls, monitor AI activity, and continuously assess third-party risk. 

Create an inventory of every AI assistant, copilot, and agent connected to enterprise systems, then review each integration for excessive permissions, unnecessary connectors, and missing activity logs before expanding AI deployments.

Interpol Flags Rising APAC Cybercrime 

Cybercrime now accounts for 30% of nationally recorded crimes in more than half of the APAC countries surveyed by Interpol. 

The report identifies phishing, ransomware, DDoS attacks, infostealers, and AI-enabled scams as key cyber threats across APAC. 

It also warns that cloud phishing and AI-powered social engineering are making traditional awareness training less effective. 

Update phishing simulations to include AI-written lures, review cloud access controls, and map incident escalation communication contacts by country before a cross-border attack occurs.

 

Security Tip of the Day

Are You Prepared for Cybercrime?

Cybercrime continues to evolve as attackers combine phishing, ransomware, AI tools, and infostealers to target organizations of every size.

How to reduce your attack surface: 

  • Strengthen identity security by using phishing-resistant MFA, enforcing least-privilege access with identity and access management (IAM) tools, and monitoring for unusual logins, privilege escalation, and other signs of account compromise.
  • Reduce your attack surface by maintaining a strong patch management program and segmenting critical systems to limit lateral movement after an initial breach.
  • Prepare for evolving threats by training users and using deepfake detection tools, while testing IR plans through tabletop exercises.

Cyber resilience is built through consistent security fundamentals, including identity protection, attack surface reduction, and operational preparedness.
