PWS:Win32/Primarypass.A Summary

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.
• 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.
• 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.
• Deletes its original binary from disk;
• Executed a process and injected code into it, probably while unpacking;
• Steals private information from local Internet browsers;
• 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\RunOnce
• Spoofs its process name and/or associated pathname to appear as a legitimate process;
• 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.
• Creates a copy of itself;
• Harvests credentials from local FTP client softwares;
• Harvests information related to installed instant messenger clients;
• Harvests information related to installed mail clients;

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 papers situated on the victim’s hard disk — so the target can no more make use of the information;
• Preventing regular accessibility to the victim’s workstation;
