What is Nog4yH4n Project ransomware? And how does it execute its attack?

Nog4yH4n Project ransomware is a new crypto-virus created based on the open source platform, HiddenTear. This new HiddenTear variant was discovered at the end of September 2018 and seems to be targeting English-speaking users and its developers appears to be from Turkey. According to security experts, this crypto-malware is still in its development phase although it can still encrypt files.
Once it infiltrates a computer, it will drop its malicious payload in the system (hidden-tear.exe). This malicious payload will connect the computer to a Command and Control server managed by the attackers. After establishing connection, it downloads other files from the remote server and places them to some system folders. It then proceeds to modify some registry entries and keys in the Windows Registry allowing itself to run on every system boot automatically. Following the system modifications, it begins to scan the system in search for files with specific formats such as:
.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp
Once it finds its targeted files, Nog4yH4n Project ransomware will encrypt them using the AES encryption algorithm. After the encryption, it appends the .locked extension to each one of the affected files. It then releases a text file named “HACKED N0G4YH4N.txt” which contains the ransom note stating:
“This computer has been hacked
Your personal files have been ecrypted. Send me BTC or food to get decryption passcode.
After that, you’ll be able to see your beloved files again.
With love… Nog4yH4n Project’)”
Cyber crooks behind Nog4yH4n Project ransomware demands a ransom in BTC in exchange for file recovery. However, this is something you must not do as you will only end up getting tricked by these crooks. So if your computer somehow got infected with this crypto-virus, the first thing you must do is to terminate it right away and then use alternative method in recovering your encrypted files without having to pay the ransom.
