  • 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.
  • At least one process apparently crashed during execution;
  • 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.;
  • A process created a hidden window;
  • The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Uses Windows utilities for basic functionality;
  • Queries information on disks, possibly for anti-virtualization. Since VMs share the same disk space so it is expected that they won’t be getting as much space as an application running on
    native hardware will have access to.
  • 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!
  • Exhibits behavior characteristic of Cerber ransomware;
  • Writes a potential ransom message to disk;
  • Checks the system manufacturer, likely for anti-virtualization;
  • Attempts to access Bitcoin/ALTCoin wallets;

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.
  • Ciphering the files situated on the target’s hard drive — so the victim can no longer make use of the information. This is the typical behavior of malware known as ransomware that encrypts a victim’s files. The cybercriminal then demands a ransom from the victim to restore access to the data upon payment.
  • Preventing regular access to the victim’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
