Microsoft Windows Defender Prevents 400,000 Dofoil Infections

Improved anti-malware detection prevented spread of cryptomining software this week, says Microsoft.

The spread of a Dofoil cryptomining campaign was contained this week in part because of Windows endpoint security platform for Windows 10, according to Microsoft researchers

Researchers write that using "behavior-based signals coupled with cloud-powered machine learning models" Windows Defender Antivirus initially blocked 80,000 instances of the Dofoil Trojan, which carried a cryptomining payload, "within milliseconds."

Over a 12-hour period, 400,000 instances total were stopped. The spread was contained in part due to Defender's cloud protection service, which shares threat intelligence to other machines running Defender on Windows 7, 8.1, or 10. (Microsoft extended support for Defender to Windows 7 and 8.1 in February.)
