In the majority of the situations, Ransom.TeslaCrypt virus will certainly advise its targets to launch funds transfer for the purpose of counteracting the modifications that the Trojan infection has presented to the target’s tool.
These alterations can be as complies with:
- 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.
- Reads data out of its own binary image. The trick that allows the malware to read data out of your computer’s memory.
Everything you run, type, or click on your computer goes through the memory. This includes passwords, bank account numbers, emails, and other confidential information. With this vulnerability, there is the potential for a malicious program to read that data.

Unlike passwords and verification codes, fingerprints are fundamental parts of user’s identities. Among the threats blocked on biometric data processing and storage systems is spyware, the malware used in phishing attacks (mostly spyware downloaders and droppers), ransomware, and Banking Trojans as posing the greatest danger.
- Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
- Uses suspicious command line tools or Windows utilities;
- Ciphering the documents situated on the sufferer’s hard drive — so the target can no more use the information;
