The Ransom Prank Ransomware is a fake file-encrypting Trojan that pretends to block your media, although its only significant attack is using its pop-up to lock the GUI. Follow the instructions as provided in this article for disabling this threat and regaining control over your PC. Anti-malware solutions also may remove the Ransom Prank Ransomware automatically without it being able to superimpose itself over the Windows interface.

One Joke with a Punchline not Worth Hearing

Although it's easy enough for even the most inexperienced of programmers to borrow code for causing encryption-based file damage, some threat actors consider even that a bridge too far for walking. Along with actual, file-locking threats, malware analysts sometimes see Trojans that include the symptoms expected of just such an infection, but without the encryption. However, these Trojans, like the Ransom Prank Ransomware, still can use misinformation to try to collect money in spite of their limited payloads.

The Ransom Prank Ransomware has no encryption functions but does include a screen-blocking one. This attack displays an interactive Web page automatically, sized to the current screen resolution, and omits the border and related UI controls. The pop-up displays a typical 'ransom note' as per file-encrypting Trojan standards, including a time restriction on paying and Bitcoin-based ransom to decrypt your media. However, this message is a bluff, as malware experts can confirm no other attack features of note in the Ransom Prank Ransomware's payload.

Like most screen-locking threats, the Ransom Prank Ransomware also includes a simple password ('12345') for removing its window and restoring access to the user interface. If this password fails, paying the ransom is a solution that malware experts discourage since con artists can accept the money and refuse services without risking a refund.

Keeping Your Desktop Prank-Free

The Ransom Prank Ransomware isn't capable of causing permanent damage to your PC's files currently but does lock the entire OS from being usable superficially. Should its threat actor change the password to a less obvious one, victims will need to recover by rebooting their PCs while also disabling the Trojan's start-up process. For most users, malware experts recommend attempting a Safe Mode-based reboot by tapping F8 during the restart process to access the menu for the Advanced Boot Options. You also can use peripheral devices like USB drives to recover your computer and override any Registry exploits that the Ransom Prank Ransomware uses for loading itself.

Although malware researchers are working on determining the Ransom Prank Ransomware's distribution model, no samples available offer evidence of how it installs itself currently. Threat actors may be bundling the Trojan with other downloads, such as fake software updates or torrents. Regardless, having anti-malware products that can uninstall or delete the Ransom Prank Ransomware automatically is your most reliable protection.

The idea of a Trojan with such a simple password being a real security problem may seem laughable. However, this password is an easily-edited string, and even a few seconds of work could make the Ransom Prank Ransomware into something that's no laughing matter.
