Backdoor.Erica.2 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.
  • 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.
  • Drops a binary and executes it. Trojan-Downloader installs itself to the system and waits until an Internet connection becomes available to connect to a remote server or website in order to download additional malware onto the infected computer.

    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • Network activity detected but not expressed in API logs. Microsoft built an API solution right into its Windows operating system it reveals network activity for all apps and programs that ran on the computer in the past 30-days. This malware hides network activity.
  • Likely virus infection of existing system binary;
  • Creates a copy of itself;
  • Ciphering the documents located on the sufferer’s hard disk drive — so the victim can no more utilize the information;

As quickly as the Trojan is successfully infused, it will either cipher the data on the target’s PC or protect against the gadget from functioning in a proper way – while likewise positioning a ransom money note that mentions the demand for the targets to impact the payment for the function of decrypting the documents or recovering the documents system back to the first problem. In many instances, the ransom money note will certainly show up when the customer restarts the COMPUTER after the system has actually already been harmed.
