More examples of trojan-type programs are Glupteba, Nymeria and Retefe. Unfortunately, these are many other trojans. Typically, programs of this type are designed to spread other malicious programs, in other words, to infect computers with additional malware. However, backdoor capabilities of Casbaneiro allow this trojan to do more than that. Either way, if a computer is infected with a trojan or any other malicious software, it should be removed immediately.

How did Casbaneiro infiltrate my computer?

Research shows that cyber criminals distribute Casbaneiro using malicious executables that are disguised as files that supposed to install or update legitimate apps such as Spotify, OneDrive and WhatsApp. Nevertheless, they could be distributing this trojan using names of other legitimate apps as well. When these executables are launched, they begin installation process of the Casbaneiro trojan. It is known that cyber criminals disguise Casbaneiro's installer as updater of some financial software. Also, they distribute this trojan through third party Windows activators that supposed to activate operating system for free. It is worth mentioning that the expected activator gets actually installed, however, it gets installed together with the Casbaneiro trojan.

How to avoid installation of malware?

Attachments in irrelevant emails that are received from unknown, suspicious addresses should not be opened. The same applies to website links. Software must be downloaded from official websites and using direct download links. Channels/tools like Peer-to-Peer networks (torrent clients, eMule, etc.), unofficial pages, third party downloaders, installers and other similar download or installation channels can be used to distribute trojans, ransomware, and other malware. Furthermore, installed software should be updated through tools or implemented functions that are provided by official software developers, and not some third party updaters. If installed software or operating system is not free, then it should not be activated through unofficial, third party updaters. It is not legal to use them and they often cause installations of malicious programs. Also, we strongly recommend to regularly scan operating systems with reputable anti-virus or anti-spyware software and make sure that it is always up-to-date. Besides, detected threats must be removed as soon as possible. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
