OpenDNS’s Umbrella Security Labs says colleges and universities are 300 percent more likely to have malware in their networks. Higher-education networks are targeted most by the so-called EXPIRO malware, a file-infecting family that has been around since 2010. EXPIRO typically infects local, removable, and network drives, and installs malicious extensions for Chrome and Firefox. The big problem on university networks is that they are, by nature, open, and IT doesn’t manage each student’s client device.”]
