Happylocker Ransomware

Happylocker Ransomware – Initial Information

Another member of HiddenTear project, Happylocker Ransomware is on the loose all over the internet. As may have heard, HiddenTear is a kind of educational ransomware project made public by a Turkish Researcher on GitHube in 2015. Since then thousands of ransomware have been created using the platform. Some of them have been reached the level of the most famous threats among Security investigators and Windows users. The Happylocker Ransomware is being distributed by using vitiated file attachments contained in Junk emails created and sent by cyberpunks, often in PDF or DOCX files housing corrupted macro scripts that download the Happylocker Ransomware onto your Windows PC. Junk Emails used to distribute the the ransomware may contain social engineering elements to trick you into opening the most infectious file. Bogus Bitcoin-based faucet (a reward system that pays computer users with BitCoin fragments) may be used to trick you into loading and executing malicious files like exploit kit or payloads. Such files may connect to a server in background just after invading your system and start downloading components of the ransomware without your awareness.

Identification of Happylocker Ransomware contamination

During initial inspection, we found that Happylocker Ransomware utilizes a military-grade file encryption standard – AES-256. This cipher allows the ransomware to corrupt your files just in few minutes. Encrypted files could not be opened or read by you until you don't remove Happylocker Ransomware and restore your files on your computer using backup or system restore point option. Afterwards, the ransomware drops 'READDDDDDD.txt' ransom note and 'READ.jpeg' file on your affected desktop.
