Companies have long sought to balance what information about their vulnerabilities they must keep secret, and what information it would benefit them to share. The names of companies leaked in internal emails from HBGary, which were made public after the attacks last month by Anonymous, may change the calculus used to determine just how much we share.

This has the salubrious effect of making it, well, okay to have been the target of an attack as a company.”]
