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.

“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.  In some circles, this seems to have lead to a complacency or belief that botnet infections are not […]

May 19th, 2009

While Microsoft may believe that its Internet Information Services 6 Web-server software issues are only limited to a data leakage issue and not necessarily a larger immediate threat, Microsoft should consider other aspects of this issue and accelerate a solution to protect the community at large.
