We know we shouldn't, but most of us do it anyway: access the Internet on Wi-Fi networks at coffee shops and airports, knowing full well those networks are not secure. Late last year, it was discovered that about 300,000 home routers in Europe were "commjacked" and all their traffic diverted to Russia. The target was financial data.
Seventeen fake cell towers were discovered in Washington, last year, some outside the White House, the Pentagon, the Russian and Israeli embassies and a few other key locations. The attackers commjacked employees' personal and work cell phones. These "towers" were not the typical 60-foot-tall cell tower, but the size of a laptop and able to intercept mobile devices within a half-mile radius. In another commjacking heist discovered last year, 5,000 high-end hotels' Wi-Fi networks were found to have been commjacked by a group Kaspersky Lab called DarkHotel. When they connected to Wi-Fi, guests were prompted to download an app containing malware. An investigation revealed that the attack had been going on for seven years.
