The Necurs botnet has recently undergone a resurgence, distributing millions of malicious emails – large swathes of which have most recently been spreading Locky ransomware. It’s also been known to deliver the Trickbot banking trojan, indicating the attackers behind it have their fingers in many pies. But not happy with just that, wow those behind Necurs – a zombie army of over five million hacked devices – are also attaching a downloader with the functionality to gather telemetery from infected victims.
Uncovered by researchers at Symantec, the Necurs downloader can take screengrabs of infected machines and send them back to a remote server. It also contains an error-reporting feature which sends information back to the attackers on any issues the downloader encounters when performing its activities.

While this new variant of the Necurs botnet is a serious problem, it is limited only to Windows computers. It does not seem to affect Macintosh, Linux, iPad, or Android devices.
