ARISGATE SECURITY BRIEF · MALWARE ALERT
Trust Is the New Attack Surface
A familiar looking tool asked someone to copy and run a command, and that's all it took. Know your firm's AI access and never paste commands you didn't write.

Security researchers recently uncovered a campaign where attackers are abusing ChatGPT Custom GPTs to deliver a remote access trojan. The attackers use a technique known as ClickFix, which tricks users into copying and running malicious commands themselves, often disguised as a fix for a technical problem. Once executed, the attack sideloads a malicious DLL file to install the RAT on the victim's machine, giving intruders remote control over the compromised system.

Why this matters for your firm

This campaign targets the exact behavior busy staff exhibit every day: trusting familiar looking tools like AI chat assistants and following what looks like a helpful troubleshooting step. A single paralegal or attorney clicking through a ClickFix prompt could hand an outside party remote access to a machine holding client files, trust account records, or privileged communications.

Florida Bar Rule 4-1.6 and Recommendation 25-1

Rule 4-1.6 requires attorneys to make reasonable efforts to prevent unauthorized access to client information. A RAT installed through a trusted AI tool is precisely the kind of unauthorized access this rule exists to prevent. Recommendation 25-1 pushes firms toward documented cybersecurity assessments, and this incident is a clear reminder that "reasonable efforts" now must account for AI enabled attack paths, not just traditional phishing.

What to do this week

  1. Train every staff member to never copy and paste commands into a terminal or run box, regardless of the source, including AI tools.
  2. Restrict or monitor which AI platforms and custom extensions staff can access on firm devices.
  3. Review endpoint protection to confirm it can detect DLL sideloading activity, not just known malware signatures.
