The Internet's biggest spam botnet Necurs has been spreading a strain of Windows ransomware known as Scarab over the last two days, security companies say.

The Necurs email botnet has made a return and, apart from spreading new variants of the Locky ransomware and the Trickybot trojan, also has new functionality that gathers telemetry data from the Windows desktop of its victims.

Security firm Symantec claims that exploit kits spread malware to users only at half the rate that email does, with one of every nine email users encountering malware in the first half of 2017.
