YafunnLocker Ransomware

YafunnLocker Ransomware Description

The YafunnLocker Ransomware, also known by the alias of CryptoLuck, is a Trojan that blocks your files through an encryption technique and creates pop-ups to persuade you into paying a ransom. Paying these ransoms doesn't always give the victims their files back, and malware experts recommend investing in backups that can offer a reliable data recovery service. Outside of restoring your files by the usual methods, keeping anti-malware products for detecting and deleting the YafunnLocker Ransomware on sight is the most efficient way to preserve your saved data.

A Bright, Bold Trojan with the Same, Old Plan of Attack

PC users often are chided to avoid opening unsafe e-mail messages or click on corrupted links, but not every security problem is necessarily visible. One of the most harmful method malware experts see for distributing threats this year is the RIG Exploit Kit. This browser-exploiting package of scripts is responsible for installing Trojans like the Alcatraz Ransomware, the latest version of the Cerber Ransomware, and the new YafunnLocker Ransomware.

Vulnerable PCs not patched against security flaws in features like Flash or JavaScript may experience a compromise as soon as their Web browser loads an infected website. The asymptomatic drive-by-download installs the YafunnLocker Ransomware, after which, the Trojan begins scanning for media to encode. Once it's encrypted, a file will have its name changed with the addition of a new extension ('[A-F0-9]{8}_luck') and be incompatible with any associated programs.

Related symptoms malware experts verified from the YafunnLocker Ransomware include:

  • The YafunnLocker Ransomware replaces the desktop wallpaper with a bright, red encryption warning-themed image.
  • The YafunnLocker Ransomware creates a Notepad file that provides minor information on its attack and how to pay its ransom, most likely meant as a backup in case its final message (see below) fails to load.
  • The YafunnLocker Ransomware also generates a pop-up in a matching red theme, containing a user interface on paying to get its decryption key.

Escaping a Countdown Towards Deletion

The YafunnLocker Ransomware places stress on victims to force payments through its inclusion of a timer component and threatens the permanent deletion of the decryption key at zero. Since even paying the ransom it demands has no guarantee of being able to decrypt anything, malware experts always encourage attempting any other data recovery options beforehand. They also haven't noted any additional attacks hard-coded in the Trojan that it links to its Web timer, which may be a bluff. Data restoration methods against file-encrypting Trojans often benefit from the availability of an uninfected backup.

Anti-malware products with browser-based threat monitors can block the RIG EK and similar attacks. You should treat deleting the YafunnLocker Ransomware as a separate process from any data recovery, which can require specialized decryption tools not yet available. However, you can provide samples to security researchers with public histories of decryption development and use traditional anti-malware products for removing the YafunnLocker Ransomware from your computer.

At the end of the day, for PC users who feel safe enough to keep no more than one copy of their files, threat actors like the YafunnLocker Ransomware's creator may be their greatest enemy.
