Trojan:Win32/Pariham.A Summary

These adjustments 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);
  • Compression (or decompression);
  • Injection with CreateRemoteThread in a remote process;
  • Attempts to connect to a dead IP:Port (1 unique times);
  • 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.
  • Repeatedly searches for a not-found process, may want to run with startbrowser=1 option;
  • 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.

  • Code injection with CreateRemoteThread in a remote process;
  • A process attempted to delay the analysis task by a long amount of time.;
  • Tries to unhook or modify Windows functions monitored by Cuckoo;
  • 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!
  • Creates or sets a registry key to a long series of bytes, possibly to store a binary or malware config;
  • Network activity contains more than one unique useragent.;
  • 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
  • Exhibits behavior characteristics of Shifu malware.;
  • Attempts to identify installed analysis tools by a known file location;
  • Attempts to identify installed AV products by registry key;
  • Detects Sunbelt Sandbox through the presence of a file;
  • Detects VirtualBox through the presence of a file;
  • Detects VMware through the presence of a file;
  • Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
  • Attempts to access Bitcoin/ALTCoin wallets;
  • Creates a slightly modified copy of itself;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the files situated on the sufferer’s hard disk drive — so the sufferer can no longer make use of the data;
  • Preventing normal access to the target’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
