What is HappyLocker?

HappyLocker is file-encryption ransomware based on Hidden Tear - an open-source ransomware project. Cyber criminals promote HappyLocker via "Instant Satoshi BOT" - a malicious application that supposedly rewards users in Bitcoins for completing various 'captchas'.

Following infiltration, HappyLocker encrypts files and appends the ".happy" extension to filenames (e.g., "sample.jpg" is renamed to "sample.jpg.happy"). Following successful encryption, HappyLocker creates a .txt ("READDDDDDD.txt") and .bmp ("READ.bmp", set as the desktop wallpaper) file, and places them on the desktop.

What kind of malware is AiraCrop?

AiraCrop is ransomware-type malware that encrypts files using asymmetric cryptography. AiraCrop append the names of encrypted files with the "._AiraCropEncrypted!" extension (some AiraCrop variants append ".airacropencrypted!").

For example, "sample.jpg" is renamed to "sample.jpg._AiraCropEncrypted!" Following successful encryption, AiraCrop creates a text file ("How to decrypt your files.txt") containing a ransom-demand message, and places it on the desktop.

Newer variants of this ransomware add HOW_TO_DECRYPT_YOUR_FILES.HTML instead of the .txt file for ransom demanding instructions.

What is WickedLocker?

WickedLocker is a file-encryption virus based on Hidden Tear - an open-source ransomware project. Following successful infiltration, WickedLocker encrypts files and file names with the ".locked" extension (e.g., "sample.jpg" is renamed to "sample.jpg.locked").

Following encryption, WickedLocker opens a pop-up window and creates a text file associated with each encrypted file. These text files are named after the encrypted files (e.g., "READ_IT_sample.txt").

What is PaySafeGen?

PaySafeGen is file encryption malware presented as a hacking tool, which supposedly generates genuine PaySafeCard codes free of charge. In fact, these claims are false. When executed, PaySafeGen encrypts various files stored on the system. During encryption, PaySafeGen appends the ".cry_" extension to the name of each encrypted file.

For instance, "sample.jpg" is renamed to "sample.jpg.cry_". After file encryption, PaySafeGen changes the desktop wallpaper and displays a pop-up window. Both contain a ransom-demand message.

What is Telecrypt?

Telecrypt is file encryption ransomware written in the Delphi (programming language) and, therefore, the virus is in the form of a binary file and must be executed manually. If run accidentally, Telecrypt encrypts various files stored on the system (e.g., .doc, .pdf, .jpg, etc.).

Research shows that there are a number of variants of this ransomware. While some do not rename encrypted files, others append the ".Xcri" extension (e.g., "sample.jpg" is renamed to "sample.jpg.Xcri"). Following successful encryption, Telecrypt downloads an executable ("Xhelp.exe"), which displays a ransom-demand message.
