Trojan:Win32/Casdet!rfn Summary

These modifications can be as complies with:

  • Executable code extraction: Cybercriminals often utilize binary packers to hinder malware analysts from reverse-engineering malicious code. Binary packers are tools that compress, encrypt, and modify the format of a malicious file. Additionally, packers can be used legitimately to protect programs against unauthorized copying or cracking.
  • Injection (inter-process);
  • Injection (Process Hollowing);
  • Creates RWX memory;
  • HTTP traffic exhibits suspicious features that may indicate malware-related activity;
  • Performs various HTTP requests;
  • The binary likely contains encrypted or compressed data: In this scenario, encryption serves as a method to conceal the code of the virus from antivirus software and virus analysts.
  • Executes a process and injects code into it, potentially during the unpacking process;
  • Checks for the presence of known debuggers and forensic tools within the Windows environment;
  • Steals private information from local Internet browsers;
  • Network activity includes multiple unique user agents;
  • Collects information about installed applications;
  • Checks the CPU name in the registry, possibly as an anti-virtualization measure;
  • Harvests credentials from local FTP client software;
  • Gathers information related to installed instant messenger clients;
  • Collects information to fingerprint the system: There are behavioral human characteristics that can be utilized to digitally identify a person and grant them access to systems, devices, or data. Unlike passwords and verification codes, fingerprints are intrinsic components of a user’s identity. Biometric data processing and storage systems block various threats, including spyware, which is commonly used in phishing attacks (primarily spyware downloaders and droppers), ransomware, and Banking Trojans, as they pose the most significant risks.

How Trojan:Win32/Casdet!rfn is distributed?

The majority of cases of Trojan:Win32/Casdet!rfn malware delivery goes to these ways:

  • Email spamming or spamming in social networks/communication platforms
  • Usage of unlicensed (hacked) programs or dubious tools
  • Malicious advertisements on the internet (ads with a malicious link or file inside)
  • The distribution of malicious advertisements on the web has been a long-standing method for spreading malware. The advice to avoid clicking on flashing advertisements on untrustworthy websites has been around as long as internet ads themselves. One can also install ad-blocking plugins for their web browser, which effectively deal with all types of ads. However, if adware is already present on your PC and generating these ads, ad blockers will prove useless.

    Email spamming became a very popular malware distribution method, since the users do not raise suspicion on notifications from DHL or Amazon about the incoming delivery. However, it is quite easy to distinguish the malevolent email from the original one. One which is send by a cybercriminals has a strange sender address – something like [email protected], while the original email address has a specific domain name ( or and can also be seen on the official website in the “Contact us” tab.

    Software bundling is a widespread practice among the virus developers. Users who hack the programs to make them usable without purchasing a license approve any offer to include another program to the pack, because they are gaining money in such a way. Check precisely the installation window for signs like “Advanced installation settings” or so. The ability to switch off the malware installation often hides under such items.

    Ransomware injection

    Changes that are made by Trojan:Win32/Casdet!rfn virus are next:

    Disabling the Windows Defender. An embedded anti-malware solution from Microsoft is a favorite target of malware creators. And since it is so easy to disable through Group Policies, every second trojan virus makes this action. Casdet!rfn is not an exception. After that step, you will not get a notification about the detected malware.

    Making several complicated manipulations with the system security settings. The virus disables not only a visible security mechanism but also turns off the methods which are used by the system to prevent malware execution. Under this term I mean the forbid to launch the VBS scripts, disabled by default MS Office macroses or remote registry editing facilities.

    Password extraction. Users who make use of a local Windows account may lose their credentials. The password of the local account is stored in a separate area of the winlogon process in encrypted form. Virus may easily call the decrypt function, and get the password of your account, as well as passwords of all users of your PC and local network.
