Trusted Third Party reportsthat FileZilla - a popular free FTP client often used in corporations - may contain malware.
In the thread The program's forum described a situation when scanned with a set of antiviruses on the site VirusTotal The program's installer turned out to contain suspicious code. The programmer's response was standard, optional third-party installers.
It later turned out that the file's hash did not match the one reported on the program's website - which the creator quipped that "the hash did not match due to a different file name." Which is obvious nonsense.
One of the more inquisitive users analyzed the performance of the installer using the CarbonBlack tool. The results are very disturbing.
It turns out that the installer, while running, creates, among other things, a process named tofufeti.exe, which opens several more. Then, 3 fragments of the .DAT file are downloaded from 3 different servers, which are combined into a whole. The file is run, and finally - deleted. This kind of action is one way for malware to bypass security.
An additional threat is that the 3 addresses mentioned have already been tied to malware distribution.
The program's developer has not provided any plausible explanation for the installer's behavior. At this stage, it should be concluded that FileZilla may be dangerous and it would be an unreasonable risk to use it on any corporate computers.
