This week's attention goes to a technique researchers are tracking: attackers quietly abusing Windows Defender exclusion settings to hide malware from antivirus scans. Security researchers have observed this method used by established malware families, allowing malicious files and folders to run completely invisible to Microsoft's built in protection once an exclusion is configured.
Most solo and small firms rely on Windows Defender as their only line of antivirus defense, often without ever reviewing exclusion lists. If an attacker, a malicious attachment, or even a careless software installer adds an exclusion, your "protected" machine stops scanning the exact folder where malware is hiding. Client documents, trust account records, and case files sit exposed with no alert ever firing.
Rule 4-1.6 requires attorneys to make reasonable efforts to prevent unauthorized access to client information. An antivirus tool with silent blind spots does not meet that bar, and you would have no way to prove otherwise after an incident. This is also the kind of gap Recommendation 25-1 is pushing firms to document through regular, recorded cybersecurity assessments rather than assuming default settings are sufficient.
This is exactly the kind of overlooked gap ArisGate exists to close for solo and small Florida law firms. We check configurations most firms never think to look at, and we document everything to support your Rule 4-1.6 and Recommendation 25-1 obligations.
