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 places 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 programs. 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 finds 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 encrypted by RSA-1024 and AES-256 due to computer security problems.
If you think your data is very important. The only way to decrypt your file is to buy my decryption tool.
else you can delete your encrypted data or reinstall your system.

Decryption does as follows:
- if you do 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 person to my email
[email protected]. I will send you the decryption tool.
Tips:
1. don’t rename your file
2. you can try some software for decryption. but finally, you will know it’s vain.
Anything you want to help. please send mail to my email [email protected].
Have a nice day .”
