What is STOP Ransomware

Tfude Ransomware, which is actually next generation of STOP Ransomware appeared in January of 2019. This virus encrypts user’s essential files, such as documents, photos, databases, music with AES encryption and adds .tfude (later started to append .tfudet and .tfudeq) extensions to affected files. This ransomware is almost identical to .puma Ransomware and .djvu Ransomware, that we described earlier, and belongs to the same authors, because it uses the same e-mail adresses (pdfhelp@india.com and pdfhelp@firemail.cc) and same BitCoin wallets. After virus finishes, it creates _openme.txt file with ransom note on the desktop and in the folders with affected files. Here is the content of this file:

From the file above, we can understand, that hackers offer 50% discount for decryption, if ransom amount is paid within 72 hours. However, this is just a trick to encourage people to pay the ransom.
