Dr.Jimbo – How Does It Infect Users

To confirm a successful infection, Dr.Jimbo Ransomware has to successfully connect to the malicious server of the cyber-criminals. To do this, it may use a malicious executable dropped by a Trojan.Downloader, which can be masked as an:

• E-mail attachment.
• Fake setups of programs.
• Fake game cracks or key generators.

In addition to that other types of attacks may be used, in correlation with malicious URLs being posted online or in spam messages:

• Exploit kit attacks.
• JavaScript attacks.

Dr.Jimbo – More About The Ransomware

After it slips past the defenses of the victim PC, most likely via using obfuscators, Dr.Jimbo may create malicious files in some of the following Windows folders:

• %AppData%
• %Roaming%
• %Desktop%
• %Temp%
• %User’s Profile%

After creating the malicious files, Dr.Jimbo ransomware might as well create registry entries in order to make one or more files run every time Windows has started and change the wallpaper of the infected computer to one with a ransom note. Here are some of the probably targeted registry keys by Dr.Jimbo:

→ 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

The encryption process used by Dr.Jimbo may be taken from other ransomware viruses. As soon as it is activated the ransomware may start scanning the computer for different file types of commonly used files, for example:

Encrypted files are no longer accessible and the file extension .encrypted is added to them. This very file extension has been reported to be seen with other ransomware viruses, like Crypren and Apocalypse viruses.
The encrypted files with such extension added to them may look like the following example:

The encryption cipher(algorithm) used to encrypt those files may be one of the following:

• RSA
• AES
• XOR

After encryption, the ransomware drops the following file so that the user can see it:

The file states the following ransom message:

The domain of the malicious e-mail address strongly suggests that there may be Romanian involvement in the development or the usage of this virus to make a profit at the user’s expense. However, it may be a trick by the cyber-criminals to simply mask their real identity.

The demanded payoff amount by Dr.Jimbo ransomware is reported to be in the range of 2 to 3 BitCoins – a hefty sum.

Also, even though it is not confirmed, Dr.Jimbo ransomware may delete backups and file history from your computer, using the vssadmin command with one of its following parameters:
