FOR END USERS
Medusa ransomware continues to attack infrastructure. Since June 2021, Medusa ransomware has targeted over 300 critical infrastructure organizations, stealing and encrypting data while demanding ransoms. They use phishing, exploit unpatched vulnerabilities, and employ legitimate tools to evade detection, engaging in double or triple extortion to pressure victims.
What you need to know: This story is a reminder that phishing is a key cybercrime entry point. Attackers stole credentials and exploited vulnerabilities, bypassing strong passwords and MFA. Encourage your end users to remain alert and mindful in the following areas:
• Spot red flags: Watch for unfamiliar senders, urgent requests, or odd attachments.
• Verify links: Hover to check URLs before clicking.
• Avoid risky downloads: Skip unapproved software that may hide malware.
• Report issues: Notify IT of suspicious activity or system oddities, quickly.
Remind them that in a digital landscape where threats lurk behind every corner, their instincts can quietly turn the tide. Encourage them to pause before they click, question what seems off, and flag the unusual.
FOR PEERS
Blind Eagle Targets Colombian Government with Malicious .url Files. Blind Eagle targets Colombian institutions with malicious .url files mimicking CVE-2024-43451, patched November 2024. Using platforms like GitHub and Google Drive, they deploy Remcos RAT, infecting thousands. A February 2025 phishing slip exposed 8075 credentials, highlighting their stealth and danger.
What you need to know: Spark conversations with your peers about evolving threats, specifically campaigns like Blind Eagle's recent shift leveraging .url files and WebDAV, and the persistent challenges surrounding NTLM. Are there opportunities to reevaluate your current security postures? How are they working around the NTLM patch? How can your organization enhance your detection of anomalous NTLM negotiations, especially those tied to WebDAV traffic? Further discuss file-sharing platform usage, from Google Drive to GitHub, and the implications for your own environments. Are your anomaly detection rules and phishing resilience exercises keeping pace? Their focus on Colombian entities provides a real-world case study.
FOR EXECUTIVES
Developer sabotaged ex-employer with kill switch activated when he was let go. A senior developer, demoted during a restructuring, sabotaged Eaton Corporation’s systems with malware and a "kill switch," locking out thousands of employees globally and causing hundreds of thousands in damages upon his termination. This highlights the critical cybersecurity risk of insider threats with high-level access.
What you need to know: This case underscores the severe threat disgruntled insiders with elevated privileges pose to businesses. Beyond operational downtime and financial losses, such incidents can damage reputation and trust. Executives must see cybersecurity as encompassing internal risks, not just external attacks. Ignoring insider threats risks business continuity and stakeholder confidence.
Bringing this to executives’ attention not only highlights a real-world example of insider risk but also positions you as a proactive leader in protecting the company’s assets and resilience:
• Proactively manage insider risks by enforcing least privilege access, limiting permissions to essentials.
• Conduct regular access reviews, especially during restructurings or terminations.
• Establish a robust offboarding process; revoke access instantly and audit systems.
• Foster security awareness and open dialogue to address employee discontent early, preventing escalation.
