      Sadly this happens, having reported hundred of vulns and dealt with dozens of angry vendors I can say that problems can be avoided, just need to be careful asking for lawyer advise and have a plan b if something goes wrong https://twitter.com/zackwhittaker/status/965571877220618240 …

      I could write a book on the insane things vendors have tried with me, but nobody would believe half the stories. 😒

      Just recently I've had a major vendor make up criminal accusations and mail them to my boss, "there's no way he could have found this without source code, this is evidence he's hacked us and stole it".

          I remember in a call the vendor CTO threatened me and want me to talk to his CEO to tell him that the vuls weren’t real and that it wasn’t CTO fault ¯\_(ツ)_/¯

          this just in: we hacked some hardware and notified vendor, it seems related hardware is used by US gov for classified information, vendor contacted GSA and I got a letter from GSA saying that anything we found should "only be reported to GSA" letter CCed CIA, NSA, FBI, USDOS...

          Finding vulnerabilities without sourcecode? Impossible? Sure, it's (usually) not easy, but c'mon, @MalwareUnicorn's dog can do reverse engineering. Her smaller dog.

          A vendor accused my employer of doing "reverse engineering" on their product. Despite me spending one full day on their site (with their collaboration) to browse the source code. Yes I found & documented the backdoor, no client wasn't happy.

          Somebody on Twitter basically tried to have me fired from my new job by threatening my employer. That was a fun conversation to have so early into a new job.

          So they adit that in their own estimation you could get in, steal code, and they wouldn't even notice?
