PlugX malware hides on USB devices to infect new Windows hosts

Security researchers have analyzed a variant of the PlugX malware that can hide malicious files on removable USB devices and then infect the Windows hosts they connect to. The malware uses what researchers call "a novel technique" that allows it to remain undetected for longer periods and could potentially spread to air-gapped systems. A sample of this PlugX variant was found by Palo Alto Network's Unit 42 team during a response to a Black Basta ransomware attack that relied on GootLoader. READ MORE...
