Core Technologies outs Citect to Associated Press-- is this ethical?

As I posted over on Joe Weiss' blog Unfettered, Core Technologies "reported exclusively" to the Associated Press about a buffer overflow vulnerability they found in CitectSCADA. The flaw is repaired, although, once again Core insists that it was "five months" before Citect responded to their notification. They made the same charge against Wonderware a month or so ago...but they didn't ever say how they had tried to contact WW or Citect-- sending emails to "info@..." probably won't get there. My continuing problem with this is that I don't think what Core (and the other security companies that gain visibility, advertising, street cred, and whatever else they want in support of additional business) is doing is ethical. Encouraging somebody to exploit a previously unknown (and according to Core, unexploited) vulnerability in Critical Infrastructure seems to me to be a dangerous, and potentially deadly practice. That's what Core is doing-- and they are doing it to advertise their services as a security consultant. If I did that to gain more readership, I'd have people correctly questioning my ethics, you bet.  Walt
