Genre Computer security

Security Now! is a weekly podcast (Internet radio show) hosted by Leo Laporte of this WEEK in TECH and Steve Gibson of Gibson Research Corporation (GRC). It is part of the TWiT.tv network [1], and the first episode was released on 19 August 2005.

Released each Thursday, Security Now! consists of a discussion between Gibson and Laporte of issues of computer security and, conversely, insecurity. Topics that have been covered include then-current security vulnerabilities, firewalls, password security, spyware, rootkits, Wi-Fi, virtual private networks (VPNs), and virtualization. In late 2005 and early 2006, the Windows Metafile vulnerability was also covered. While it remains to be officially confirmed, it is believed that the title is a reference to the Seinfeld episode The Serenity Now.

Security Now! is distributed via its main podcast RSS feed (link) and on the GRC Security Now! page [2]. As with many podcasts, the audio is encoded in MP3 format, with higher quality (64 kilobits per second) and lower quality (16 kbit/s) versions available for listeners on low bandwidth connections (such as dial-up) or those with limited storage space.

As part of GRC's section on the podcast, supplementary notes and transcripts of each show are available in plain text and PDF formats. Through Frappr, an online map is available for people to place a marker on, creating a geographical picture of where Security Now! listeners around the world live [3].

[edit] Listener feedback

Every fourth episode (referred to as the "mod 4 podcast"), Gibson and Laporte devote an episode to answering questions and responding to feedback provided by Security Now! listeners. This began on 1 December 2005. The GRC web page has a feedback form allowing listeners to submit their comments and questions [4].

[edit] Windows Metafile vulnerability claims

In episode 22 of Security Now! in January 2006, Steve Gibson made an accusation[4] that Microsoft may have intentionally put a backdoor into the Windows Metafile processing code of the Windows 2000 and XP operating systems.

Gibson claimed that while reverse engineering the Windows Metafile format, he could only run arbitrary code if he used a "nonsensical" value in the metafile. His conclusion was that Microsoft had intentionally designed Windows in this way to allow them to use the feature as a backdoor to running code on Windows computers without the knowledge of the user.

Gibson's claim was refuted[5] by Stephen Toulouse of Microsoft in an MSDN blog posting on 13 January 2006, stating that Gibson's observations applied only to metafiles containing one data record, and that the behavior was not intentional.
