The retiring US Forces Korea commander's valediction warns of North Korea's cyber threat.

Softpedia reports that an unnamed company has sustained a 100 Gbps denial-of-service attack. Whoever conducted it used no amplification, which means the attackers had plenty of bandwidth.

More attacks exploit the IE bug Operation Deputy Dog used last month.

Phishing is much on people's minds today, as the familiar "Microsoft support" bogus calls return and other attackers use a bogus T-Mobile MMS message. Facebook's Graph Search may prove an interesting tool, but it also creates what CIO calls a "phishing wonderland." ICS managers are again warned of the threat to SCADA systems phishing presents.

Some analysts think that enterprise attack surfaces are contracting, but others (including Chertoff Group experts) call major companies' cyber security "appalling."

Defense wonks worry that Britain's MoD is about to prompt a "cyber arms race" and call for arms control, but this seems to overlook the cyber arms races—and cyber wars, false flags and all—that have been on-going for some years. See, for example, Estonia's experience of being on the receiving end of cyber aggression.

Medical device manufacturers and users express increasing concern over vulnerabilities to hacking.

The US Government has "shut down," but details of what this means in practice remain unclear. We do know that our friends at the Defense Cyber Crime Center (DC3) are still tweeting. We don't know whether they're on the job or whether they queued the tweets up Monday, but in either case, bravo DC3.
