PatPending writes with this report on companies taking aggressive steps to deal with electronic attacks: "Known in the cyber security industry as "active defense" or "strike-back" technology, the reprisals range from modest steps to distract and delay a hacker to more controversial measures. Security experts say they even know of some cases where companies have taken action that could violate laws in the United States or other countries, such as hiring contractors to hack the assailant's own systems. Other security experts say a more aggressive posture is unlikely to have a significant impact in the near term in the overall fight against cybercriminals and Internet espionage. Veteran government and private officials warn that much of the activity is too risky to make sense, citing the chances for escalation and collateral damage." If you've been involved in such an action, how did it work out for you?
