The Crypt0 HT Ransomware is a minor version of Hidden Tear, the file-locking Trojan. Along with blocking your files, this version of the threat also adds random extensions to their names, generates pop-up alerts, and asks you to pay money via a ransom-trafficking website. Withhold your money unless no other recovery options are possible, and use appropriate anti-malware programs for deleting the Crypt0 HT Ransomware and preventing it from locking any additional copies of your media.

The Ever-Changing Meaning of Names in Trojan Campaigns

It is never entirely safe to use the self-advertised labels of Trojans for determining what they are, and a particularly recent campaign from the Crypt0 HT Ransomware is adding additional confusion to potential infections. While the Crypt0 HT Ransomware uses the name of a 2016 member of the DetoxCrypto Ransomware group, it's a separate threat most closely deriving from Utku Sen's hijacked Hidden Tear project. Using inappropriate data recovery software to resolve the Crypt0 HT Ransomware infections only may worsen any issues by corrupting the files that this Trojan already encrypts.

The Crypt0 HT Ransomware is disguising itself as a non-threatening file to gain access to the victim's PC. Its payload uses a basic, but secure encryption protocol with AES or Rijndael to lock different types of media on an infected system. Once a file is encoded and no longer opens, the user can identify it from the random string of characters that the Crypt0 HT Ransomware appends to the ends of the name. Malware experts find no other signs of ongoing symptoms for this attack, at this time.

After concluding the above function, the Crypt0 HT Ransomware creates a simple, Windows pop-up that gives the user a six-day limit to pay a ransom, with details following in a dropped Web page. The latter provides a link to a TOR website, which is asking for no less than half a Bitcoin, or over eight thousand USD, for transferring over the individualized decryption code currently. Decryption through free methods, or recovering from a backup, always should be the user's default response since Bitcoin carries no protections against fraud.

Converting Banking Customers into Extortion Victims

Tactics for distributing the Crypt0 HT Ransomware, which is Windows-specific and targets English speakers, pretend that the Trojan's installer is some form of banking information. Traditionally, these delivery methods also surround themselves with supporting details, such as e-mail messages that are forged to look like alerts from a major bank. Security programs with accurate rates for detecting Hidden Tear also should block the Crypt0 HT Ransomware during these infection attempts.

Even though malware researchers have yet to determine the possibility of free decryption programs arriving for the Crypt0 HT Ransomware, other data restoration solutions are available for responsible PC users. Backing up your content to a location most likely of being secure, such as a portable drive or a cloud service, removes the risk of long-term data loss from most file-locking Trojans. Since encryption isn't an instant process, your active anti-malware protection also may delete the Crypt0 HT Ransomware at any point during or after the infection, as well.

The Crypt0 HT Ransomware's potentially confusing choice of name could lead to victims making the mistake of using an incompatible decryption tool to resolve the issue of any locked files. However, for individuals who are practicing better data-storing habits, the mere act of having a backup can neuter the Crypt0 HT Ransomware just like most forms of Hidden Tear.
