What is TBHRanso ransomware? And how does it implement its attack?

TBHRanso ransomware functions as a crypto-malware threat first discovered on the last week of November this year. TBHRanso is designed to stealthily infiltrate the system and encrypt the user-generated files. This ransomware is another variant of Hidden Tear – an open source platform used by cyber crooks in developing ransomware threats. The file types listed below are some of the files that TBHRanso targets once it enters the system and starts its attck:
.3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .efx, .eps, .fla, .flv, .gif, .h, .idml, .iff, .indb, .indd, .indl, .indt, .inx, .jar, .java, .jpeg, .jpg, .js, .m3u, .m3u8, .m4u, .max, .mdb, .mid, .mkv, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .pdb, .pdf, .php, .plb, .pmd, .png, .pot, .potm, .potx, .ppam, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prel, .prproj, .ps, .psd, .py, .ra, .rar, .raw, .rb, .rtf, .sdf, .sdf, .ses, .sldm, .sldx, .sql, .svg, .swf, .tif, .txt, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .xla, .xlam, .xll, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xqx, .xqx, .zip.
Security experts noted that TBHRanso uses a combination of AES and RSA ciphers in corrupting the files. It also adds the .locked extension at the end of each files’ names. After the encryption, it delivers its ransom note in a file named READ_IT.txt which is dropped into the desktop of the computer. This text file contains the following context:
“This computer has been hacked
Your personal files have been encrypted. Send me 100$ BTC to (1MMphN2Rc5xCf4TGTVXQ6B8VSbYdQyCgYS) to get decryption passcode. After that, SEND ME YOUR (PC NAME) TO [email protected], you’ll be able to see your beloved files again.
With love… TBHRanso Virus :’)”
It isn’t clear yet if this ransomware deletes the shadow volume copies of the files. Nevertheless, with or without these shadow volume copies, you shouldn’t pay the ransom even though you only consider $100 an affordable amount. No matter how cheap the ransom is, paying it won’t really solve the problem – in fact you might only end up losing more money. So trying out alternative ways to recover your files is a lot better.
How does TBHRanso ransomware disseminate its malicious payload?
TBHRanso ransomware disseminates its malicious payload using the most common distribution method which is spam email. Cyber crooks sends emails containing an attachment or an embedded link which is used to install TBHRanso into the victim’s computer. Cyber criminals often disguise their malicious emails as if they’re sent out from well-known companies like PayPal, Amazon, Facebook, etc. because of this many users have already fallen for their tricks. Usually, crooks use a corrupted Microsoft Word document or PDF file which contains malicious macro scripts used to download and install the malware into the computer.
