I recently visited the website for a large, reputable company which serves a malicious script (it's a knockoff of one of the major analytics apps, with an inconspicuous, intentional typo in the source URL). Additionally, the company serves a niche market, and likely doesn't have a large tech team, so their website hadn't been set up with HTTPS.

Fortunately, my antimalware software blocked the script, so I decided to look around at least the landing page to see if there's some kind of administrative (or even support) contact.

Not having found one, and not having found anything useful after doing a WHOIS query, I noticed that they accept Facebook messages via their official page.

Is it generally risky to notify a company of a vulnerability using such unofficial channels?

  • As a side note -- I'm welcoming better tag suggestions. I couldn't find any more relevant ones.

  • intentional typo? By whom?If its The company itself made intentional typo then,may be they themselves want to be unethical.

  • @Sravan I doubt it; they might serve a niche market, but this is still a fairly large company, and this would be a big hit against their reputation (especially since it's quite conspicuous for anyone with a basic antimalware).

  • If you are going to get something like a bounty from them, you may consider reporting it via proper private channels. Otherwise, i feel better just ignore it.

    can't hurt to ask where they want it from fb, if not just dump it into the comment...

It turns out that in this instance, contacting them over unofficial means (Facebook private messaging) resulted in a response within about 48 hours followed by a quick patch to remove the injected script.

I can't provide a general, non-anecdotal answer to this question, though.
