Blackzd Ransomware – How Did I Get Infected

Among the primary methods of infection, the Blackzd ransomware uses is the malspam. This is essentially the massive spam of e-mails to the addresses of the victims with a pretext that the messages sent are legitimate and they have an important e-mail attachment that has to be opened. This very attachment may be a loader or a dropper or any other infection malware which may download the malicious payload of Blackzd Ransomware on your computer system.

Other methods of infection include uploading the malicious files of Blackzd ransomware as fake setups, game cracks, key generators or any other executable files that may look legitimate and fool the victim, they are such.

Inspection of Blackzd Ransomware

The Blackzd ransomware is your typical ransom malware. The virus causes an infection to your computer after which drops it’s malicious files on it. These malicious files consist of the main executable of Blackzd ransomware as well as several support files, all of which may be located in the following Windows directories:

  • %AppData%
  • %Roaming%
  • %Local%
  • %LocalLow%
  • %Temp%
  • %SystemDrive%

After the virus drops it’s files, Blackzd ransomware may begin to interfere with the Windows processes, gaining itself administrative privileges which are later used to encrypt the files on your computer. The virus may also modify the Windows Registry Editor, attacking the following registry sub-keys which make it possible for Blackzd to run on Windows boot:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

After adding value strings in those registry sub-keys the Blackzd ransomware virus may also delete the shadow-volume copies of the infected computer. This is achieved by running the following commands in a hidden manner, without you noticing it:

→ process call create “cmd.exe /c
vssadmin.exe delete shadows /all /quiet
bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures

After doing so, the Blackzd ransomware may begin encrypting your important files and drop it’s ransom note file, which is named README_{random}_{random}.txt and has the following message:

Naturally, this software is only available to the cyber-criminals, which is the main reason why they ask money for it. The Blackzd ransomware is very careful to not encrypt important Windows files, since it may damage your operating system. The virus however may encrypt files on your computer that may be important to your, for example:

  • Documents.
  • Pictures.
  • Videos.
  • Music files.
  • Archived files.
  • Others.

After doing so, Blackzd ransomware may completely rename those files, which results in them having random names, like the following:

Usually the first couple of symbols and letters are the same for each file, but the second part of the name is random for each single file.
