Win32/Kryptik.HDSD 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.
- 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.

- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
- Checks the CPU name from registry, possibly for anti-virtualization;
- 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 records found on the target’s hard disk — so the target can no more use the information;
- Preventing regular accessibility to the victim’s workstation;
