FBI Apple AntiSec Chess Match
September 12th, 2012
The denials by the FBI and Apple that unique device identifiers (UDIDs) of Apple devices were breached would seem to put to rest Anonymous spinoff AntiSec’s claim that it was able to steal 12 million UDIDs from Special Agent Christopher Stangl’s notebook computer.

June 6th, 2012
LinkedIn – the online professional networking site which I suspect many Optimal Security blog readers use – has apparently been hacked, resulting in something like 6.5M SHA-1 hashed passwords being posted in a Russian hacker site. This evolving situation will certainly be updated through-out the day (and beyond), so I don’t want to recap the [...]

“Micro-Botnet” – The Cybercriminal’s Choice for Enterprise Data Stealing?
September 28th, 2009
Last winter and spring we all watched with interest the headlines heralding the spread of the Confickr botnet. The under-reported part of the story was that fact that well-patched enterprise networks were largely unaffected by Confickr’s bloom.

August 4th, 2009
The recent attacks on U.S. and South Korean IT infrastructure has once again raised awareness around national cybersecurity issues here in the States.

Miscellaneous interesting news / tidbits I’ve run across whilst trying to keep up with/clean out my RSS feed … Cyberczar.
