Trojan:Win32/Tiggre!plock 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.
  • 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.
  • Attempts to connect to a dead IP:Port (5 unique times);
  • A process created a hidden window;
  • Performs some HTTP requests;
  • Unconventionial language used in binary resources: Russian;
  • The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Executed a very long command line or script command which may be indicative of chained commands or obfuscation;
  • A scripting utility was executed;
  • Uses Windows utilities for basic functionality;
  • Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the records situated on the sufferer’s hard drive — so the victim can no longer make use of the information;
  • Preventing regular accessibility to the victim’s workstation;

Trojan:Win32/Tiggre!plock distribution methods

The biggest share of Trojan:Win32/Wacatac.D!ml virus distribution is after these methods:

  • Email spam or spamming in the Facebook/Twitter
  • Unlicensed software usage
  • Malvertising on the Web (ads with a malicious redirect inside)
  • Ransomware injection

    Software bundling is a widespread practice among the virus developers. Users who hack the programs to make them usable without purchasing a license approve any offer to include another program to the pack, because they are gaining money in such a way. Check precisely the installation window for signs like “Advanced installation settings” or so. The ability to switch off the malware installation often hides under such items.

    Email spamming became a very popular malware distribution method, since the users do not raise suspicion on notifications from DHL or Amazon about the incoming delivery. However, it is quite easy to distinguish the malevolent email from the original one. One which is send by a cybercriminals has a strange sender address – something like f0138skbeu@gmail.com, while the original email address has a specific domain name (@amazon.com or @dhl.us) and can also be seen on the official website in the “Contact us” tab.

    Malicious advertisements on the web, however, is an old-timer of malware distribution. And the advice to stop clicking the blinking advertisements on untrustworthy websites exists as long as the ads on the Internet. You can also install ad blocking plugins for your web browser – they will deal with any kind of ads. However, if they are generated by adware which is already present on your PC, ad blockers will be useless.

    Visible effects of Trojan:Win32/Tiggre!plock virus presence.

Nonetheless, the common sign of the fact that you PC was hijacked with the use of backdoor is that lives its own life – mouse pointer moves without any mouse move, windows are appearing and closing autonomously; your browser may start searching something while you are sitting in front of the monitor with your hands off the input devices.

    vAfter being injected into the victim’s PC, Backdoor:Win32/Bladabindi!ml starts its malicious activity by connecting to the server of its distributors. After the successful connection, the backdoor receives the instructions and begins making the deep system changes. Group Policies and system registry are one of the most “loved” targets. The manner in which these elements are changed depends on the purpose the backdoor distributors choose – joining to the botnet, injecting other viruses, scaring the target or getting access to its data.
