The SANS Internet Storm Center reports that attackers are not always turning to advanced malware or novel techniques. In a recent diary entry, the organization highlights how the legitimate ScreenConnect client is being abused by threat actors. Rather than deploying custom code, these attackers are leveraging a trusted remote access application to further their objectives.
This pattern is notable because it underscores a broader trend: attackers often prefer to misuse existing, legitimate software. Since tools like ScreenConnect are designed for remote administration, their presence on a system may not immediately raise red flags. The SANS diary serves as a reminder that defenders need to watch for unusual usage of common administrative tools, not just malware signatures.
The report does not provide specific details on the campaign's targets or outcomes, but the warning is clear. Organizations using remote access software should monitor for unexpected connections or configurations, as the line between legitimate use and abuse can be thin.
