How to remove [[email protected]].Z9 ransomware

Easy [[email protected]].Z9 ransomware removal guide

Z9 or otherwise called [[email protected]].Z9 ransomware is a file-locking virus belongs to Dharma ransomware family. Cyber security researcher, Raby discovered this variant. As a rule, ransomware type programs encrypt stored files, change filenames and create ransom note which contains ransom demanding message for the data decryption. As Z9 encrypts, the filenames of the encrypted files will receive .Z9 extension plus victims’ associated ID number (that is unique for each victim) and [[email protected]] email – that belongs to the crooks behind the ransomware. A file myphoto.jpg will become[[email protected]].Z9. To provide ransom demanding message, the ransomware creates FILES ENCRYPTED.txt file and displays a pop-up window.

The .txt file states that files have been encrypted and that the victims have to establish the contact t o the developers behind [[email protected]].Z9 ransomware via email address provided. This is what the FILES ENCRYPTED.txt file says:

all your data has been locked us

You want to return?

write email [email protected] or [email protected]

The pop-up window provides further detailed information.  It states that the encryption is done using RSA-1024 encryption algorithm. To get the files back, contact the developers via [[email protected]] email address that must include provided ID number provided. An alternate email is provided on the pop-up window. As per the note, this email ([email protected]) is used for the contact if no any response is received as a reply from the first email. It further states that the files decryption requires using a unique decryption tool that the developers store on some remote server for limited days. In order to provide a proof that the decryption tool is really working, the developers offer free decryption service and users can send 1 file (non-archived 1MB or less in size) with the letter they send. However, the other files decryption is not free and for this the users have to purchase the decryption tool. The price of the tool is not mentioned on the note and it may be told later after when users contact to the developers. All that is given about the payment in the note is that it is to be accepted in Bitcoin only. The page also instructs how to generate Bitcoin. At the end, the pop-up window contains a scary note that prevents users from using third party software and renaming the files or, otherwise they will lose their files for permanently.

How did ransomware intrude in?

In most of the cases, malicious programs are being distributed via scam campaigns, Trojans, untrustworthy downloading channels, fake software updaters and unofficial software activation tools. It is common for any ransomware distribution of using scam campaigns in which spam emails containing infectious files or links as attachments, if opened – users are asked to enable the files to run macros command that lead malicious software installation. Trojans are malicious programs, that if intrudes, will cause chain infections. In other word, the Trojans install other malicious malware on your OS. Freeware download websites, free file hosting sites, unofficial pages, third party downloadders, and p2p networks are some common example of untrustworthy channels that offer rogue applications. Fake software updaters exploit bugs/flaws of outdated software or directly download malware instead of providing update. Cracking tools lead computer infection by supposedly bypassing activation key for paid software.
