Evasive – another malware based on open source ransomware project

Ransom note by Evasive ransomware virus

Evasive is a file-encrypting virus that is written based on the HiddenTear[1] code. The virus uses AES cryptography to corrupt data on the targeted computer and appends .locked file extension. Following successful encryption procedure, malware drops a ransom note in READ_ME.txt file where crooks ask to contact them via email.

Evasive ransomware targets the most popular file types in order to cause more damage to the victim and make him or her to pay the ransom. The virus is known to corrupt these types of files:

.aspx, .cpp, .csv, .doc, .docx, .h, .html, .jpg, .jsp, .lnk, .mdb, .odt, .pdf, .php, .png, .ppt, .pptx, .psd, .pst, .rar, .sql, .txt, .xls, .xlsx, .xml, .zip.

In the text file, authors of the Evasive virus tell victims to contact them via getkeys@tutanota.com within 12 hours since the attack. They also give a backup email (weknownit@mail2tor.com) if something goes wrong with the primary one. Additionally, criminals warn that the decryption key is available only for 48 hours.

However, it might be just a psychological terror and attempts to scare the victim into paying the ransom. Security experts from SemVirus.pt[2] suggest staying calm and do not rush into following hackers’ demands. They will ask to pay some Bitcoins, but they may never give you a working decryption software. Thus, it’s better to remove Evasive and try alternative recovery methods.

The malicious program makes numerous changes to the system. For this reason, it’s not recommended to eliminate crypto-virus manually. You should opt for the automatic Evasive removal method which requires scanning the system with Reimage or similar malware removal tools.

However, if ransomware prevents you from installing or using security software, reboot to Safe Mode with Networking or try System Restore methods (explanation below) to disable Evasive and run its automatic elimination.

Distribution techniques of the crypto-malware

The virus is most likely to enter the system when a user opens a malicious email attachment. Malware payload might be presented as a safe looking Word, PDF or another file. However, you should always look up for the signs of phishing email[3] instead of rushing to open the attachment.

Additionally, Evasive might infiltrate with the help of:

  • malicious ads;
  • bogus downloads;
  • fake updates;
  • exploit kits.

Keep in mind that even the strongest antivirus cannot protect you fully from the cyber attack. You have to watch your clicks and downloads in order not to be misled by dangerous content.
