What is Backdoor:Win32/Cycbot!pz virus?

Backdoor:Win32/Cycbot!pz Summary

Summarizingly, Backdoor:Win32/Cycbot!pz malware activities in the infected system are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • Reads data out of its own binary image;
  • CAPE extracted potentially suspicious content;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Creates a copy of itself;
  • Touches a file containing cookies, possibly for information gathering;
  • Yara rule detections observed from a process memory dump/dropped files/CAPE;
  • Encrypting the files located on the target’s drive — so the victim cannot check these documents;
  • Blocking the launching of .exe files of anti-virus apps
  • Blocking the launching of installation files of security tools

The algorithms used in Backdoor:Win32/Cycbot!pz (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these terrible things without delay – it may require up to several hours to cipher all of your files. Therefore, seeing the Backdoor:Win32/Cycbot!pz detection is a clear signal that you must begin the removal procedure.

Where did I get the Backdoor:Win32/Cycbot!pz?

Common tactics of Backdoor:Win32/Cycbot!pz injection are standard for all other ransomware variants. Those are one-day landing websites where users are offered to download and install the free app, so-called bait emails and hacktools. Bait emails are a relatively modern tactic in malware distribution – you get the email that mimics some normal notifications about shipments or bank service conditions shifts. Within the email, there is a malicious MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Preventing it looks quite simple, but still needs a lot of recognition. Malware can hide in different spots, and it is much better to prevent it even before it gets into your PC than to rely on an anti-malware program. Standard cybersecurity awareness is just an important thing in the modern-day world, even if your interaction with a PC stays on YouTube videos. That can save you a lot of time and money which you would spend while trying to find a fixing guide.
