NPPH Ransomware

Posted: September 16, 2020

The NPPH Ransomware is a file-locking Trojan that comes from a Ransomware-as-a-Service known as the STOP Ransomware. Users should have backups for protecting their work from its attacks, which can block files with impenetrable encryption. Appropriate anti-malware services also should find and remove the NPPH Ransomware without issues.

Unobtrusive Names on Media-Destroying Trojans

The STOP Ransomware, also identifiable by the name of one of its earliest releases, Djvu Ransomware, is one of the most populous Ransomware-as-a-Services for the year easily. Owing prominence to ease of use, potent encryption security, and convenient features like wiping backups, it's a source of many of the file-locker Trojans that malware experts see out in the wild. The current example of the NPPH Ransomware shows that this RaaS is either remaining profitable or at least keeping up the appearance of it.

The NPPH Ransomware's name isn't too dissimilar from other relatives like the Oonn Ransomware, the OGDO Ransomware, the KASP Ransomware, or the Vari Ransomware, all of which label themselves with four random characters. This brand-label is part of one of the Trojans' symptoms, which appends extra extensions to files, while also blocking them with a secure encryption conversion routine. Once encrypted, a file, such as a document or a picture, can't open in their associated programs. Restoring the name has no impact on the encryption.

Another part of the NPPH Ransomware's naming convention shows that its threat actors may plan on placing the Trojan manually or through unobtrusive methods like a hidden drive-by-download through a corrupted document. Multiple versions of the NPPH Ransomware installer are using various, random names, such as '61CD' or '8A44,' which provides no enticing reason for users' downloading them. However, installation tactics related to it could use opening gambits such as fake invoices sent by e-mail, or even torrents for game cracks.

A Stopping Point for Trojans that will not Stop by Themselves

The STOP Ransomware variations are as numerous as the threat actor affiliates who hire this software and leverage it against any likely targets, which can include home users just as much as unprotected business entities. Windows users can expect few symptoms until the NPPH Ransomware begins its encryption routine, which may block, for the sake of ransoming them, most documents and other digital media formats. Any valuable content should have a sufficiently-protected backup; malware experts especially recommend using a secondary storage device.

The NPPH Ransomware creates ransom notes that are standard for its family, such as text messages requesting hundreds of dollars in Bitcoins. As usual, the Trojan also sets a deadline before the expense rises, which might push some victims into paying instead of considering other solutions. However, most file-locker Trojans use an unbreakable form of encryption, and this unfortunate reality also applies to current-year versions of the STOP Ransomware business.

A strong anti-malware program for Windows should detect and delete the NPPH Ransomware infections adequately. They also can serve as preemptive security by blocking the various script and vulnerability-based attacks that could let a hacker obtain access to the PC or trigger drive-by-downloads.

Its executable doesn't draw any attention, but hidden programs can cause more than a little damage while the user overlooks them. Anyone not paying attention to their network security, their backups, or what's on their PC might find that the NPPH Ransomware, or a Trojan just like it, is making wide-ranging changes.
