Distribution of EvilLock Ransomware

EvilLock ransomware is possibly distributed via malicious dropper. This type of malware is developed to launch viruses by installing them on targeted computers. As a way of its distribution, it is most likely to be used spam emails that contain malicious web links, attachments or both. The email sender may pose as someone that belongs to the team of a legitimate service. The malicious intenders usually aim to provoke a feeling of emergency in the users in order to force them to interact with the content or the attachment.

Another distribution way may be freeware software that comes bundled with the malicious payloads of EvilLock ransomware.

In some cases, the crooks create a web page that contains the malicious payloads of EvilLock ransomware in its source code. Furthermore, they may compromise the code of official web pages transforming them into means of ransomware distribution. Via attack techniques, they set an automatic download process. Thus all malicious files could land on the computer after a single visit to such compromised website. Except in the text of an email, the malicious web links may be included in malicious advertising campaigns.

Exploit kits might also be used for the distribution of EvilLock ransomware.

Security Tips:

  • Use free online services like VirusTotal that scan and analyze suspicious files and URLs. They could efficiently detect all kinds of malware thanks to the access to the information gained by various antivirus engines, website scanners, file and URL analysis tools and user uploads.
  • Search for the official website of the software you want to download. A download from legitimate source will guarantee the safety of your computer.

More About the EvilLock Crypto Virus Infection

EvilLock ransomware is a new version of Javascript Evil ransomware. It is a file-encrypting type of ransomware that utilizes powerful AES encipher algorithm that transforms particular files making them unusable. Each encrypted file gets the extension .evillock at the end of the original name.

The EvilLock crypto virus is designed to scan all disks and drives for specific file types that should be enciphered. So, the analyses of professional security engineers disclose the following file types as part of EvilLock’s target list:

.3fr, .accdb, .ai, .arw, .bay, .cdr, .cer, .certs, .cr2, .crt, .crw, .dbf, .dcr, .der, .dng, .doc, .dwg, .dxf, .dxg, .eps, .erf, .img, .indd, .jpg, .kdc, .mdb, .mdf, .mef, .mrw, .nef, .nrw, .odb, .odc, .odm, .odp, .ods, .odt, .orf, .p12, .p7b, .p7c, .pdd, .pef, .pem, .pfx, .ppt, .psd, .pst, .ptx, .pub, .r3d, .raf, .raw, .rtf, .rw2, .rwl, .sr2, .srf, .srw, .wb2, .wpd, .wps, .x3f, .xlk, .xls

Except the malicious extension .evillock as part of all encrypted data, EvilLock ransomware creates two files that contain a message from the attackers to the victims. The files are named HOW_TO_DECRYPT_YOUR_FILES.TXT and HOW_TO_DECRYPT_YOUR_FILES.HTML. Both files present identical text that’s only the file type that differs.

The text of EvilLocker ransom note reads:

“Hello.

Just google how to buy bitcoins in your country. You have only 3 days to deadline!
After, your key will be deleted!
List of encrypted files
P.S. I can decrypt one encrypted file as evidence that there is decrypt”

The attackers urge all victims to contact them to [email protected] by sending an email with the ID code in order to provide further information about the decryption of .evillocked virus files. The ransom message indicates that a payment of 0.3 BTC (at the present moment it equals to $303.8) need to be paid for the unique key that will decrypt all enciphered files.

However, no matter that they give a word that the files will be decrypted after the payment, there is no guarantee this will happen. So, if you are a victim of EvilLock ransomware, it is better to avoid any negotiations with cyber criminals and make an effort to contend the infection by yourself using cyber security means.
