Highly Sophisticated Malware Attacks Home and Small Office Routers
Security researchers have uncovered an unusually sophisticated malware that has been targeting small office/home office (SOHO) routers for nearly two years, taking advantage of the pandemic and rapid shift to remote work. Such routers are rarely monitored or up-to-date, making them attractive targets for hackers to reach adjacent corporate networks. According to Lumen’s Black Lotus…
