quietman7 1 Report post Posted March 13 Files encrypted with the .kroput extensions is the newest variant of STOP (DJVU) Ransomware. You can submit (upload) samples of encrypted files, ransom notes and any contact email addresses or hyperlinks provided by the malware developer to ID Ransomware (IDR) for assistance with identification and confirmation of the infection. This is a service that helps identify what ransomware may have encrypted your files. Please read here for a summary of this infection, it's variants and possible decryption solutions with instructions (including what to do if the decrypter does not work).

quietman7 1 Report post Posted March 14 STOPDecrypter was updated to include support for the .kroput variant if you were hit by the OFFLINE KEY - "upOacGl1yOz9XbrhjX9UR2M0j8i03YwVB0pXr1t1" as explained in here. Please read the instructions here (including what to do if the decrypter does not work). Demonslay335 (Michael Gillespie) is the creator of STOPDecrypter. He is a trusted Security Colleague (Expert) here at Emsisoft, a ransomware researcher/analyst with the MalwareHunterTeam, the creator of ID Ransomware (IDR).

Israel 0 Report post Posted March 25 Hi GT500....i think this is a new id..it keeps popping up amongst some of my skipped files..[*] ID: MMSFFsw52SZ3rPnHDpabInv00XrWHFVQyupJy9hC.... i'll upload the stopdecrypter log file soon Quote Share this post Link to post Share on other sites
GT500 591 Report post Posted March 25 5 hours ago, Israel said: upOacGl1yOz9XbrhjX9UR2M0j8i03YwVB0pXr1t1 This is a new offline ID that is in the latest version of STOPDecrypter (published today). Redownload it, and any files that use that ID should be decryptable. 3 hours ago, Israel said: MMSFFsw52SZ3rPnHDpabInv00XrWHFVQyupJy9hC This is almost certainly an online key, which means files that have this ID will more than likely not be decryptable. Michael Gillespie (the guy who made STOPDecrypter) will need the MAC address of the effected computer in order to archive this in case he can figure out the private key later. It should be in STOPDecrypter's logs when you run it on the computer to decrypt the files. 5 hours ago, Israel said: can i brute force it or not... It's technically possible, if you don't mind waiting for a few thousand years for it to finish. In general, if brute forcing a key for encrypted files is viable (as in it will finish in a reasonable amount of time), then we'll release a decryption tool that is capable of doing it.

Amigo-A 41 Report post Posted March 26 If the identifier of the encrypted files is still changing, then perhaps the malicious file is still in the system. Moreover it is necessary to check and reset the host-file. All known STOP-Djvu variants of the Promo subgroup modify it. Most of the known STOP ransomware attacks occurred due to the use of broken or repackaged installers of well-known programs, ranging from MS Office to large application programs.

Amigo-A 41 Report post Posted March 26 It's simple, but I am not a support representative. According to the rules of any forum, only support representatives should do this. How to check the PC for the presence of an active infection you will be advised by the forum support service representatives. Quote Share this post Link to post Share on other sites
Amigo-A 41 Report post Posted March 26 The full list of addresses is in my article about STOP Ransomware under the spoiler - Update of March 1, 2019. But the list may change. You can check for a modified file by trying to open these sites. www.emsisoft.com - this you have already opened, if still here. www.windowsupdate.com www.microsoft.com www.ds.download.windowsupdate.com www.update.microsoft.com www.virustotal.com www.drweb.com www.eset.com www.comodo.com www.mcafee.com If all these sites open in your browser, then the host-file has not been modified. Download Image This image is only part of an extensive list. At the beginning of March there were 502 addresses with repetitions with www and without www. I checked the file from yesterday's variants with the extension .proden. This host-file has not changed. But there are already new variants. I have not received any samples yet. This infection is very active. Extortionists act brazenly and are not afraid of anything. Perhaps now something else will add. Quote Share this post Link to post Share on other sites
Amigo-A 41 Report post Posted March 26 This STOP Ransomware has a special file delself.bat for self-deletion after encryption, but there may be several active malware on the PC, including different versions and different types. We observed a case of how three different Crypto-Ransomware worked simultaneously. Just a victim without thinking about the situation launched various hacked programs and they at a real time encrypted the files each according to his plan. As a result, all files were encrypted several times and had different extensions with repetitions. is it necessary to say that deciphering such a "crypto porridge" is unrealistic.
