What does the pop-up with PUA:Win32/Bitrepeyp.B detection mean?

The PUA:Win32/Bitrepeyp.B detection you can see in the lower right corner is displayed to you by Microsoft Defender. That anti-malware software is good at scanning, but prone to be basically unstable. It is unprotected to malware invasions, it has a glitchy interface and problematic malware clearing capabilities. For this reason, the pop-up which says about the Bitrepeyp is rather just an alert that Defender has recognized it. To remove it, you will likely need to make use of a separate anti-malware program.

PUA Behaviour

Click to expand
  • The virus attempts to delay the analysis task;
  • It reads data from its own binary image. This trick allows the malware to extract data from your computer’s memory.

    Every action you perform, such as running applications, typing, or clicking, goes through the memory. This includes sensitive information like passwords, bank account numbers, emails, and more. This vulnerability enables malicious programs to access and read that data.

  • It drops a binary and executes it. Trojan-Downloader installs itself on the system and waits for an internet connection to become available. It then connects to a remote server or website to download additional malware onto the infected computer.
  • Creates or sets a registry key to a long series of bytes, potentially to store a binary or malware config;
  • It installs itself for autorun at Windows startup. A simple tactic involves placing shortcut links (.lnk extension) in the Windows startup folder located at:
    C:\Users\[user-name]\AppData\Roaming\Microsoft\Windows\StartMenu\Programs\Startup. This causes Windows to launch the application every time [user-name] logs into Windows.

    The same action can be performed using registry run keys 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
  • It engages in network activity that is not logged in the API. Microsoft has integrated an API solution into its Windows operating system that logs network activity for all apps and programs that have run on the computer in the past 30 days. However, this malware manages to conceal its network activity.
  • Exhibits anomalous binary characteristics. This technique is used to hide the virus’s code from antivirus programs and virus analysts.

Is PUA:Win32/Bitrepeyp.B dangerous?

I have already mentioned that PUA:Win32/Bitrepeyp.B PUA is not as harmless as it claims to be. The “legitimate and effective” tool may unexpectedly uncover itself as a downloader trojan, spyware, backdoor, or coin miner malware.

That still does not imply that you have to panic – possibly, this unpleasant thing has not succeeded to do bad things to your PC.

The particular harm to your system may be created not just because of the malware injection. A huge share of suspicious programs, like the Bitrepeyp application is, is just poorly developed. Possibly, their actions are rather helpful than pointless if done on specific system configurations, however, not on each one. That’s how an uncomplicated system optimization tool may cause disorder with constant BSODs on your system. Any type of interruptions to the system registry are unsafe, and they are a lot more unsafe if performed with such programs.

How did I get this virus?

It is not easy to trace the origins of malware on your PC. Nowadays, things are mixed, and distribution methods chosen by adware 5 years ago may be utilized by spyware nowadays. But if we abstract from the exact distribution method and will think about why it works, the reply will be quite basic – low level of cybersecurity knowledge. Individuals press on promotions on odd sites, open the pop-ups they receive in their web browsers, call the “Microsoft tech support” thinking that the strange banner that states about malware is true. It is important to recognize what is legitimate – to prevent misconceptions when trying to determine a virus.

Nowadays, there are two of the most extensive tactics of malware distribution – bait emails and also injection into a hacked program. While the first one is not so easy to evade – you must know a lot to understand a counterfeit – the 2nd one is very easy to handle: just do not use cracked apps.
