Defray ransomware strikes hospitals and companies
Defray virus defines a new file-encrypting threat which seeks to encrypt victim’s files with AES-256 algorithm. The very key is encrypted with RSA-2048. The malware is currently mainly spread in the UK and the US countries. Here are the main features of the malware:
- encrypts data with AES-256 and RSA-2048 algorithm combination
- demands $5000 in ransom
- targets mainly selected companies, education institutions, and hospitals
- spreads via .doc files
- disables startup recovery and monitors Task Manager commands
- deletes shadow volume copies
Furthermore, the cyber criminals present three email addresses: firstname.lastname@example.org, email@example.com, and firstname.lastname@example.org.
Though the email domains suggest that perpetrator might be a Russian speaker, it might be only a diversion as the ransom note is written in the sophisticated and correct English manner. Despite the warnings noted in the ransom message, we urge you to remove Defray malware. Reimage or Malwarebytes Anti Malware might be of assistance in this process.
Since the malware does not target all companies globally, but only a selected number of them, it is likely that the perpetrator or a group of them are organized and attempt to extort money rather than cause global chaos as were the cases with WannaCry and Petya.A.
Many unanswered questions
After a targeted user clicks on the infected .doc file, they will see a counterfeited message supposedly containing an integrated video message. In order to activate the ransomware, the victims have to launch the video. Since the malware targets hospitals, the file was called “Patient Report.”
Interestingly, the malware was already detected on August 15. At that time, the infected .doc file contained a supposed video including a video presentation. The malware gained its name due to the request command to defrayable-listings.000webhostapp[.]com. In addition, the malware is known to target a number of different file formats. The malware is not likely to append any exceptional file extensions.
Defray ransomware also leaves two files – FILES.txt and HELP.txt — with the identical content. The message does not contain any exaggerated warning. Here is a short extract of it:

Malware distribution range remains low
Though the distribution range is still quite low since the crypto-malware targets only selected companies, educational and medical institutions in the US and UK, it still employs quite diverse transmission techniques.
It spreads mainly through spam emails. Thus, beware that the file containing this malware might be named as the file supposedly sent from an official institution. The file may also be named as an invoice. Such emails also contain the lack of proper credentials or typos.
Note that phishing sites may also facilitate Defray hijack. In order to ward off its trojan, you should update your security tools. Having a couple of different type of these programs might be a more wise decision. Now let us proceed to Defray removal.
