What is STOP Ransomware

Important information
Please, do not confuse the .adobe files encrypted by the STOP Ransomware described in this article with similar files encrypted by the Dharma Ransomware, analyzed previously. These ones can be decrypted, unlike ones from Dharma. Read the article to understand the difference.

This particular sample of Adobe Ransomware is, in fact, a continuation of STOP Ransomware family. This virus attacks files, that can be important for average user, like documents, photos, databases, music, enciphers them with AES encryption and adds .adobe (one “e” in the end), .adobee (two “e”s in the end) extensions to affected files. This creates a mess, because there are several different ransomware families using this extension after encryption. All these viruses use different algorithms, however .adobe and .adobee files encrypted by STOP Ransomware can be deciphered using STOPDecrypter (provided below). STOP (.adobe) virus uses same e-mail addresses (pdfhelp@india.com and pdfhelp@firemail.cc). Versions with .adobe and .adobee extensions create _openme.txt file with ransom note on the desktop and in the folders with affected files. Here are the contents of these files:

Unlike previous versions, this one gives clear information about the cost of decryption, which is $980 (or $490 if it is paid within 72 hours). However, this is just a trick, to encourage people to pay the ransom. Often authors of the ransomware don’t send any decryptor. We recommend you to remove executables of STOP Ransomware and use decryption tools available for .adobe files. Save those encrypted files, that cannot be decoded yet to the time, when decryption tool will be updated. Before that, you should try manual instructions provided in this article to restore files. Software used for recovery of removed files can also help to return some of the copies of the files, that were removed by users earlier. Follow steps, given on this page, to remove STOP Ransomware and decrypt .adobe or .adobee files in Windows 10, Windows 8 and Windows 7.
