.sifreli Ransomware – Delivery

The ransomware infection can be triggered only by single file once it is running on the system. However, this file is usually distributed being embedded or hidden in other files like zip archives, documents, PDFs and other. Such malicious files can be attached to emails or send via social media channels. Hackers like to use email addresses and subjects that will entice you to read the email and open the attachment. Once you do it, the corrupted file will deliver the ransomware. The malicious ransomware payload may also be injected into the code of web pages and then spread as links to those pages. These sites may be cologne versions of well-known websites of agencies and services like a local mobile telephone operator, your bank, and online stores. Again phishing emails and social media channels, as well as online advertisements, are likely to be used for distribution of corrupted links.

.sifreli File Virus – Detailed Overview

The word “sifreli” is Turkish and means encrypted in English and that is also the extension used by the ransomware for the encrypted files. The infection begins when the ransomware payload is running on the system. As .sifreli file virus is believed to be programmed to perform various malicious activities, it is possible to drop and create additional malware files in following Windows folders:

  • %Temp%
  • %Roaming%
  • %UserProfile%
  • %AppData%

The threat may spawn various processes in order to remain undetected by installed security tools during the encryption process. The removal process may be a tricky task as .sifreli ransomware has the functionality to create new values in Windows Registry to ensure its permanent presence on the system. Registry keys Run and RunOnce probably have added malicious values that allow the ransomware to display its ransom message once it encrypts files.

The message is written in Turkish and is being displayed as an annoying pop-up window, which is not possible to be closed. Below you can see the full message:
