Since HBSS was identified as the security software that caught the 'virus' I was immediately skeptical. Why? Because HBSS has found and deleted mission-critical software on classified networks before. HBSS was deployed in a hurry because security personnel wanted to lock the network down, and one of the steps that got skipped in a lot of places was coordinating what software is and isn't permitted on the network. Down at the operational level, this translates to an overworked captain or lieutenant passing the memo to whoever in the comms shop has time to do an install (ask yourself: why isn't this person busy?). HBSS gets installed and starts throwing up pop-up windows, and the sergeant, with no training or policy to guide him, helpfully starts making the same kinds of judgments your parents make: "What's SYSTEM32? Sounds dangerous. Deleted!"

Deeply deeply misinformed. The Missile Defense Agency press release is better than the Reuters article and a thousand times better than the Slashdot headline blurb. Some corrections:

1. Two targets were destroyed - one liquid and one solid fueled. This puts the lie to the above comment, and the Slashdot article that implies that they only shot a liquid-fueled target because it was easier. Furthermore, the solid-fueled target was identical to one that the ALTB had destroyed in flight a week earlier.

2. The first target was launched from a "sea platform", not a submarine, and is much more likely to have been a SCUD or SCUD simulator on a barge. The U.S. Navy has never permitted liquid-fueled missiles aboard their submarines because a fuel or oxidizer leak could kill the crew.

Toasting in an epic bread.

Abandonware is murky but you can find install files for many abandonware titles online as well.

Black bag = breaking and entering to steal information; a meatspace attack on someone's files, like Watergate.

False Flag = committing an act while disguised as one's enemy so that the consequences accrue to that enemy, like the bombing of the Al-Askari mosque.
