SectopRAT hides in modified software components, enabling browser data theft and remote control
Investigating a SectopRAT compromise, FortiGuard Labs found the Trojan hidden in a modified legitimate software component. It can capture screenshots, steal browser credentials and cookies, and remotely administer the computer.
Source Facts
An analysis dated 24 September describes attackers placing malicious content in files associated with audio software, then loading a trojan into memory. A familiar program name alone therefore does not establish that its executing content is trustworthy.
The research explicitly says no evidence was found that the vendor distributed infected software, and current evidence does not support classifying the incident as a supply chain attack. The focus is on altered components and endpoint anomalies, not an accusation against the vendor.
Checking software provenance, integrity and execution location is more reliable than relying on its name.
