A new variant of Rapid Ransomware is currently being distributed using malspam that pretends to be from the Internal Revenue Service. First detected by Derek Knight, this campaign is a mixup of countries with the IRS being a U.S. entity, the send being a UK email address, and the spam attachment being in German.
A new malspam campaign is underway that is pretending to be PDF receipts, but instead installs the GandCrab ransomware on a victim's computer. This is done through a series of malicious documents that ultimately install the ransomware via a PowerShell script.
A new malspam campaign is underway that is distributing a GlobeImposter variant that appends the ..doc extension to encrypted files. This malspam is pretending to photos being sent to the recipient and will have a subject line that starts in a similar way to "Emailing: IMG_20171221_".
The "Blank Slate" malspam campaign has switched to distributing a GlobeImposter variant that appends the .crypt extension to encrypted files. This downloaded executable is also code signed to make it appear more legitimate.
