Most of the situations, Trojan.Jorik infection will instruct its targets to initiate funds transfer for the function of counteracting the changes that the Trojan infection has presented to the target’s tool.

Trojan.Jorik Summary

These alterations can be as follows:

• Executable code extraction. Cybercriminals often use binary packers to hinder the malicious code from reverse-engineered by malware analysts. A packer is a tool that compresses, encrypts, and modifies a malicious file’s format. Sometimes packers can be used for legitimate ends, for example, to protect a program against cracking or copying.
• Injection (inter-process);
• Injection (Process Hollowing);
• Creates RWX memory. There is a security trick with memory regions that allows an attacker to fill a buffer with a shellcode and then execute it. Filling a buffer with shellcode isn’t a big deal, it’s just data. The problem arises when the attacker is able to control the instruction pointer (EIP), usually by corrupting a function’s stack frame using a stack-based buffer overflow, and then changing the flow of execution by assigning this pointer to the address of the shellcode.
• A process attempted to delay the analysis task.;
• Attempts to connect to a dead IP:Port (6 unique times);
• Repeatedly searches for a not-found process, may want to run with startbrowser=1 option;
• Performs some HTTP requests;
• Unconventionial language used in binary resources: Hebrew;
• The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
• Detects Sandboxie through the presence of a library;
• Executed a process and injected code into it, probably while unpacking;
• Attempts to remove evidence of file being downloaded from the Internet;
• Attempts to repeatedly call a single API many times in order to delay analysis time. This significantly complicates the work of the virus analyzer. Typical malware tactics!
• A system process is generating network traffic likely as a result of process injection;
• Installs itself for autorun at Windows startup. There is simple tactic using the Windows startup folder located at:
  C:\Users\[user-name]\AppData\Roaming\Microsoft\Windows\StartMenu\Programs\Startup. Shortcut links (.lnk extension) placed in this folder will cause Windows to launch the application each time [user-name] logs into Windows.

  The registry run keys perform the same action, and can be located in different 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
• Creates a hidden or system file. The malware adds the hidden attribute to every file and folder on your system, so it appears as if everything has been deleted from your hard drive.
• Checks the presence of disk drives in the registry, possibly for anti-virtualization;
• Creates a copy of itself;
• Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
• Ciphering the records situated on the target’s hard disk — so the target can no more use the data;
• Preventing regular accessibility to the victim’s workstation;

Trojan.Jorik

The most regular channels through which Trojan.Jorik Ransomware Trojans are injected are:

• By ways of phishing emails;
• As an effect of user winding up on a source that hosts a malicious software program;
