Threat Metric

Threat Level: 10/10
Infected PCs: 28
First Seen: October 26, 2017
OS(es) Affected: Windows


The Trick-Or-Treat Ransomware is a Trojan that generates encryption-themed pop-ups that may ask you to pay money for restoring the files that it damages. Because this threat is in development, the details of any data-locking features it may have in the future are strictly speculative, although malware experts recommend assuming that it constitutes a risk to any media on an infected PC. Have your anti-malware programs remove the Trick-Or-Treat Ransomware securely and, if any local content suffers damage in the meantime, use backups for recovery.

Digital Fright in Development

Somewhat later than usual, 2017 is seeing its first mid-development, file-locking threat with a Halloween theme: the Trick-Or-Treat Ransomware. Analysis of this program by malware experts confirmed that the Trojan has only bare-bones functionality, for now, and can't cause permanent damage to the victim's media. However, is extremely likely that a future update to take place within the next few days will improve the Trick-Or-Treat Ransomware's attack capabilities.

The Trick-Or-Treat Ransomware is a Windows software that uses default forms features to generate its pop-up alerts, which claim that the victim is under attack by harmful encryption. If ever fully implemented, such a function could encode and block documents, photos, audio, and other formats with no symptoms. Threat actors often use Trojans like the Trick-Or-Treat Ransomware for locking the contents of the desktop, local documents folders, and downloads, among other locations.

While the Trick-Or-Treat Ransomware's Halloween killer-themed window does provide a decryption button to unlock your files, it has no function associated with the UI or additional, ransom-related information for the user to read currently. Malware experts recommend trying all other methods of unlocking data before you follow the traditional recommendations of threat actors, which often require paying a non-refundable cryptocurrency for a decryptor that may not work as advertised.

Numbing the Scares that Come in Trojan Packaging

The Trick-Or-Treat Ransomware's current build provides the basic template of an attack that could collect ransoms in return for locking the victim's media but doesn't have any of its core, data-threatening functions implemented. However, families like the Globe Ransomware, Hidden Tear, and EDA2 already offer straightforward means for con artists to use re-purpose preexisting code for such campaigns. Since an update to the Trick-Or-Treat Ransomware could come at any time, users should assume that the Trojan is capable of damaging files with an encoding method for which there may not be a cure necessarily.

PC users can protect documents and other, often-locked formats of media by saving backups to less vulnerable locations, including detachable storage and cloud-based servers. The Trick-Or-Treat Ransomware is not yet in a state of being ready for wild deployment but is likely to circulate through already-noted exploits, of which, malware analysts emphasize e-mail attachments, malicious web-browsing scripts, and fake downloads especially. Slightly over a dozen brands in the PC security sector are detecting and removing the Trick-Or-Treat Ransomware correctly, although they usually will identify it as being a 'fake' file-locking threat, thanks to its incomplete payload.

Con artists appreciate the power of holiday-themed social engineering for luring victims into doing what they want. No matter how frightening its iconography might be, the Trick-Or-Treat Ransomware offers the same poor deal as any, less 'spooky' Trojan: the prospect of paying money and getting nothing out of it to save your files.
