.mich Files Virus – How Does It Infect

Similar to the previous variant of LockCrypt ransomware which used brute-forcing attacks, this version of the virus may be spread via exploits that utilize RDP (Remote Desktop Protocol) on the victim’s computer. These exploits take advantage of:

  • Weak passwords and lack of two-factor authentication for RDP access.
  • The allowing of incoming RDP connections from any IP address on the net.
  • Users usually login after a lot of failed login attempts, instead of being locked out.

According to reports, the previous versions of LockCrypt ransomware were also reported to be connected to Satan ransomware in some way, which is the result of a virus that is advertised as an RaaS (Ransomware-as-a-service).

The main methods via which such malicious files may be delivered onto servers and computers are via web links or files. Such objects can be encountered in multiple different types of locations, the crooks use to get inexperienced victims to click on, such as:

  • Malicious e-mail attachments or fake buttons that often imitate big companies or organizations.
  • Malicious files, posing as legitimate installers, setup wizards, cracks, key generators, patches or other license activators for software.
  • Malicious browser redirects to the infection URL as a result of the victim having adware or other forms of PUPs that cause browser redirects without any consent.

LockCrypt .mich Virus – Activity

Once the .mich files ransomware has already infected your computer, the malware may begin to drop it’s malicious payload files. These files are primarily malicious modules that perform different activities without you even realizing it. They are often randomly named and may reside in the following Windows directories:

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

Once the files are dropped, the .mich files variant of LockCrypt ransomware may perform different unwanted activities on the victim’s computer among which may be to modify the Windows Registry sub-keys by adding custom value entries with data In them. This data may point to the actual location of the malicious files, especially if the value entries have the following locations:

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

In addition to this, the .mich ransomware may also make sure that the shadow volume copies on your computer are permanently gone, so that you cannot recover the files in it without these copies. The .mich variant of LockCrypt(https://sensorstechforum.com/remove-lockcrypt-ransomware-restore-1btc-files/), may use the following types of commands as an administrator in Windows Command prompt to delete the copies and disable system recovery:

→ bcdedit /set bootstatuspolicy ignoreallfailures
bcdedit /set recoveryenabled No
bcdedit /set {default} bootstatuspolicy ignoreallfailures
bcdedit /set {default} recoveryenabled No
vssadmin delete shadows /for={volume} /oldest /all /shadow={ID of the Shadow} /quiet

After this has been done, .mich files virus may drop a .txt file containing it’s ransom note, which gave 24 hours deadline to pay for the decryption of your files in BitCoins via writing to anonymous e-mail.
