The .uzltzyc Ransomware – How Did I Get Infected

One way to become a victim of this devastating virus is to click on malicious URL web links as well as malicious email attachments. The malicious files may be concealed in archives and via obfuscators. The malicious payload usually consists of one or more files from the following file formats.

  • .exe .bat .cmd .vbs .dll .tmp

Users should also beware of exploit kits and Trojans that are used to initially infect the computer after which downloads the malware onto the user PC via a foreign host.

The .uzltzyc Ransomware In Detail

This ransomware is believed to generate an extension based on some type of mechanism when a computer has been initially infected. Once the ransomware has been downloaded it may begin to deploy various files of different character in key Windows locations:

  • %temp%
  • %AppData%
  • %Users%
  • %Windows%

The dropped files may be of several types. They may resemble an active process such as notepad.exe or svchost.exe. They might also contain random file names such as 9d23823.exe. Another possibility is that they carry a name of a program installed on the user PC.

After the files are dropped, the malware then may change Windows settings by modified the Windows Registry editor to make its malicious files run every time Windows starts. The usual key used for this is the following:

  • “HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”

After this, the ransomware may begin to scan for and immediately encrypt your important files. It looks for most types of images, documents, video files, audio files, presentations and others. What is more, the ransomware may even have the ability to scan and encrypt files in flash or other external drives connected to the user PC.

After encrypting the files it leaves a ransom note, notifying the user that the files are encoded with a strong encryption algorithm and further scaring him that he should pay a large sum of money in BTC, most likely via onion networking (Tor). They may feature randomly generated email addresses that have the .onion domain extension on them to protect their privacy during the extortion process.
