Nulltica Ransomware – In-Depth Analysis
Nulltica is a virus that encrypts your files and extorts you to pay a ransom to get them decrypted. Malware researchers have discovered that it is a variant of the HiddenTear open-source project and that its own decryptor might not even work.
Nulltica ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.
That ransom note can be viewed right down here:
It reads the following:
Your files have been blocked
Your files is encrypted (AES 256). You need a individual key to unlock your files.
Instruction how to unlock:
1. Create bitcoin wallet (coinbase, bitpay or any else)
2. Pay 50 usd to this wallet (bank card, transfer)
3. Send 50 usd (if you don’t know how many usd = btc – calculate with this website http://www.coindesk(.)com/calculator/ – for now 50 usd = 0.02 BTC
4. Okay, now get your wallet address and put in on the left side, below “If you already paid”
5. Click “unlock and remove the program”
6. That’s it.
Warning: If you already paid and you have information “We don’t have your payment yet”, you must waiting.. (Usually max. 12h)
Pay 50 usd to this BTC address
If you already paid
Enter the bitcoin address which you sent
Unlock and remove the program
The note of the Nulltica ransomware states that your files are encrypted. The ransom stated as payment for potentially unlocking your files is food or BitCoin. However, you should NOT under any circumstances pay any ransom. Your files may not get restored, and nobody could guarantee that. Moreover, giving money to cybercriminals will likely motivate them to create more ransomware viruses or commit other crimes.
Nulltica Ransomware – Encryption Process
As Nulltica ransomware is a HiddenTear variant it could seek to encrypt files with these extensions:
→.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
Every single file that gets encrypted will receive the same extension appended to it, which is .lock. The encryption algorithm which is implemented is undoubtedly AES since it is a variant of the HiddenTear open-source ransomware project. Interestingly enough, if you click on “Unlock” your files will get encrypted further and the extension .unlock will get added. And that is even if you paid the demanded ransom sum.
The Nulltica cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
If the command stated above is executed that would make the encryption process even more efficient as it will eliminate one of the possible ways for restoring your data. If your computer machine was infected with this ransomware and your files are locked, read on through to find out how you could potentially recover your data.
