4G hotspots can be hacked, according to security researchers who shared their findings at Def Con this weekend. The team at Pen Test Partners claimed to have found "multiple vulnerabilities" in devices sourced from well known vendors. "A lot of existing 4G modems and routers are pretty insecure," the team explained. "We found critical remotely-exploitable flaws in a selection of devices from a variety of vendors, without having to do too much work."
Public hotspots are a known security issue, but new research suggests even private hotspots could be wide-open to attack.
