FlightGear Download contains malware

Postby Ford.p51 » Wed Sep 29, 2021 4:10 pm

Hello,

The current Flight Gear download is packed with a known Cryptocurrency miner. This is preventing us from updating our older versions of FlightGear, because our organization and many others have safeguards in place to prevent the installation of such malware. Is it possible to update the download without the crypto miner as part of the package?

Thanks for your time.

i don't know where you are getting your FG from but there is no, absolutely none, crypto currency stuff in it at all...

please provide a link to where you are getting your FG from...

Flightgear.org and sourceforge.net.

That's... worrying. VirusTotal link?

Edit: I just downloaded FlightGear-2020.3.11-web.exe and FlightGear-2020.3.11.exe and tested them with ClamAV, both come through with no detections.

It looks like a false positive.

Releases are also available at: https://download.flightgear.org/builds/2020.3/ .

Virus Total results are all clean:

FlightGear-2020.3.11-web.exe: sourceforge (link), download.flightgear.org (link)

FlightGear-2020.3.11.exe: download.flightgear.org (link)

2020.3.11 /bin/fgfs.exe : from my Windows install (link)

These download.flightgear.org file urls can be put into virus total (not sure the same trick works for sourceforge, as the url goes to a download page). Sourceforge would also put shared files through malware checkers, and maybe upload to virus total - e.g. the installers already had a virus total entry from a while ago.

I'm not sure how a Windows cryptocurrency miner can get into the official release of opensource software(?) - the installers are created in an automated Jenkins build server (link) and everything should be open/visible.

Do you have a way of confirming this e.g. know of the checker that gives a positive result? It's looks like false positive(?), your IT people should have a look at Virus Total. For a false positive, your IT department should let the developers of the malware checker know. Otherwise you should probably contact the core developers on the fg-devel mailing list.

(Since everything is open, it's also possible for your organisation to build/compile FlightGear yourself - see link.)

Kind regards

It looks like the URL option on VirusTotal only checks if the URL has been flagged in a "bad link list" and does not download and scan the file.

I see. The web installer FlightGear-2020.3.11-web.exe contains all the Windows binary files (executable & dll), so it should show up there. It's clean. As was the fgfs.exe file. There's a size limit of 650 MB so the larger installer isn't uploadable.

FlightGear-2020.3.11-web.exe manual upload results are all clean: link

Ford.p51's IT department should let the developers of their malware checker know about the false positive (or maybe there's a malware infestation on their systems that inserts a cryptominer, easy enough to upload executable files to Virus Total to have it scanned by the major malware checkers).

Kind regards

Sorry for my slow response, got busy with other stuff.

I will ask that they provide evidence of the crypto miner - it may be monday before I get anything back from them though.
