What is Tellyouthepass ransomware? And how does it implement its attack?
Tellyouthepass ransomware is a crypto-virus designed to lock important files in an infected computer, leaving them inaccessible to users. It was discovered in the second half of March 2019 and based on its code snippets, it appears to be related to OpJerusalem ransomware. This new crypto-virus uses a combination of AES 256 and RSA 1024 ciphers in locking files. It also uses a “.locked” extension to its encrypted files.
The instant this crypto-malware launches its attack, it drops a malicious payload that establishes a connection to a remote C&C server and from there, it downloads its other components and place them on several system folders. These components are then used to launch or repress system processes. It scans the computer for digital strings of specific programs like Firewall, virtual host machine, sandbox environment, and antivirus program. Once it finds these programs, it either disables them or removes them from the computer to prevent them from interfering with the attack. After disabling or removing these programs, it alters some entries in the Windows Registry allowing it to execute its attack automatically. Following system modification, it will scan the system for files with these formats:
.3dm, .3ds, .3g2, .3gp, .aif, .apk, .app, .asf, .asp, .avi, .bak, .bat, .bin, .bmp, .cbr, .cer, .cfg, .cfm, .cgi, .cmd, .com, .cpp, .crx, .csr, .css, .csv, .cue, .dat, .dbf, .dcr, .dds, .deb, .dem, .der, .dmg, .dmp, .doc, .dtd, .dwg, .dxf, .eps, .exe, .fla, .flv, .fnt, .fon, .gam, .ged, .gif, .gpx, .hqx, .htm, .ics, .iff, .iso, .jar, .jpg, .jsp, .key, .kml, .kmz, .log, .lua, .m3u, .m4a, .m4v, .max, .mdb, .mdf, .mid, .mim, .mov, .mp3, .mp4, .mpa, .mpg, .msg, .msi, .nes, .obj, .odt, .otf, .pct, .pdb, .pdf, .php, .pkg, .png, .pps, .ppt, .psd, .rar, .rom, .rpm, .rss, .rtf, .sav, .sdf, .sln, .sql, .srt, .svg, .swf, .tar, .tex, .tga, .thm, .tif, .tmp, .ttf, .txt, .uue, .vcd, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .wsf, .xlr, .xls, .xml, .yuv, .zip
After it find its targeted files, Tellyouthepass ransomware will apply both the AES 256 and RSA 1024 ciphers during the encryption. Following file encryption, it adds the “.locked” suffix to all the encrypted files and drops an html file named “README.html” which has the following content:
“I am so sorry ! All your files have been encryptd by RSA-1024 and AES-256 due to a computer security problems.
If you think your data is very important .The only way to decrypt your file is to buy my decrytion tool .
else you can delete your encrypted data or reinstall your system.
Your personid :
Decrytion do as follows:
- if you not own bitcoin,you can buy it online on some websites. like https://localbitcoins.net/ or https://www.coinbase.com/ .
- send 0.2 btc to my wallet address 1CLWBxbBKddQTUuhsUsn8izq2crUAgGYZ1.
- send your btc transfer screenshots and your persionid to my email
[email protected] . i will send you decrytion tool.
1.don’t rename your file
2.you can try some software to decrytion . but finally you will kown it’s vain .
Anything you want to help . please send mail to my email [email protected]
Have a nice day .”

- HKEY_CURRENT_USER\Control Panel\Desktop
Step 11: Delete the registry keys and sub-keys created by Tellyouthepass ransomware.
Step12. Close the Registry Editor and empty the Recycle Bin.
Try to recover your encrypted files using the Shadow Volume copies
Restoring your encrypted files using Windows’ Previous Versions feature will only be effective if Tellyouthepass ransomware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot.
To restore the encrypted file, right-click on it and select Properties, a new window will pop-up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.
After you’ve covered the steps provided above, you need to continue the removal process of Tellyouthepass ransomware using a reliable program like [product-name]. How? Follow the advanced removal steps below.
