Re: Sourceforge pidgin download page blocked by google chrome as malicious

Philippe VIALLE spake unto us the following wisdom:
 if I may, that's the binary file (Pidgin-2.10.11.exe) that was downloaded
 that seems to get blocked (in fact, local detection of malicious files by
 browser itself).

OK, this is good information, thank you.

The Pidgin Windows installer (typically not Pidgin itself) has been
blocked by quite a few anti-virus and anti-malware apps in the past,
due to the installer package we use (whatever it is) *also* being used
by malware.

Perhaps that's what is going on here.

It is *also* certainly the case that several Pidgin download URLs were
issued to Google in a DMCA takedown notice.  The company that issued
them is now backtracking (possibly due to actual liability for this
act under some European jurisdictions in which both the company in
question and Google have offices), but it may be or become a problem.
It may not be this problem.

Sourceforge pidgin download page blocked by google chrome as malicious

2015-02-24 Thread Bogdan Harjoc
Tried to get pidgin-2.10.11 for windows from pidgin.im, and after the 5
second delay on sourceforge, was greeted by a red page in chrome, saying
the site was blacklisted. I downloaded the file anyway and chrome deleted
it after the download completed, calling the .exe 'malicious' as well.

Virustotal says the file is clean (

), maybe someone at google should be politely asked to drop sourceforge.net
from their blacklist ?

Cheers,
Bogdan

This is probably due to a recent, well-known bogus DMCA takedown
notice.  I expect the courts will straighten it out for us.

Re: Sourceforge pidgin download page blocked by google chrome as malicious

Guys,

if I may, that's the binary file (Pidgin-2.10.11.exe) that was downloaded
that seems to get blocked (in fact, local detection of malicious files by
browser itself).

Here is an example of such an alert with a Chrome derivative browser
(Dragon):

Despite my efforts, I could not reproduce any scenario where this was the
download URL that was blocked, therefore I believe this is a file-based
detection.

Now if you really look at VirusTotal, the Pidgin installer is not supposed
to be fully clean:

- Rising AV repots it as PE:Trojan.Win32.Generic.141A9A33!337287731
- Clam AV detects it as PUA
- Symantec reputation reports a suspicious.insight

This might be due to a detection of screen capture capability (look at
Zemana results), but can't be sure right now, just thinking out loud.
Anyway, I would try to report this to Google, as a potential FP.

My 2 cents,
