The Register on a presentation by Bruce Schneier in London where he basically states we stand on the brink of global cyber war:

During a keynote presentation, Schneier focused on a detailed commentary on last year’s attack on Sony Pictures. After months of doubting North Korea’s involvement in the attack Schneier was finally convinced of its role by a mid January article by David Sanger in the New York Times.

Other theories — most notably that a disgruntled insider collaborated with elements of Anonymous to launch the attack — were widely touted in the weeks following the attack. This illustrates the wider point that attributing attacks in cyberspace is very hard, Schneier said.

“You can be attacked and not be sure if it’s a nuclear-powered government or two guys in a basement,” Schneier noted.

The security industry has developed technology to rebuff high volume, unfocused attacks. However, skilled and focused attackers, commonly referred to in the infused biz as advanced persistent threats (APTs), or otherwise known as state-sponsored cyberspies, remain a huge challenge.

“A sufficiently skilled, funded and motivated attacker will never fail to get in,” Schneier said. The “high skill, high focused” attack thrown against Sony would have floored most every target, he added.

“Fundamentally, I don’t think any of us could withstand this type of attack from this type of adversary,” Schneier concluded.

It sure is hard to argue with this.
