“There are two variations of packages—those imitating HHS are often accompanied by letters referencing COVID-19 guidelines enclosed with a USB; and those imitating Amazon arrived in a decorative gift box containing a fraudulent thank you letter, counterfeit gift card, and a USB.”
The FBI also confirmed that all packages contained LilyGO-branded USBs which, if plugged into device, could execute a ‘BadUSB’ attack and infect it with the dangerous malware software.
The Record added that, in most cases investigated by the US agency, the group would obtain administrative access and then “move laterally to other local systems.”
