Rant of the Week

PC store told it can't claim full cyber-crime insurance after social-engineering attack

A Minnesota computer store suing its crime insurance provider has had its case dismissed, with the courts saying it was a clear instance of social engineering, a crime for which the insurer was only liable to cover a fraction of total losses.

SJ Computers alleged in a November lawsuit [PDF] that Travelers Casualty and Surety Co. owed it far more than paid on a claim for nearly $600,000 in losses due to a successful business email compromise (BEC) attack.

According to its website, SJ Computers is a Microsoft Authorized Refurbisher, reselling Dell, HP, Lenovo and Acer products, as well as providing tech services including software installs and upgrades.

Travelers, which filed a motion to dismiss, said SJ's policy clearly delineated between computer fraud and social engineering fraud. The motion was granted [PDF] with prejudice last Friday.

Billy Big Balls of the Week

Janet Jackson music video declared a cybersecurity exploit

The music video for Janet Jackson's 1989 pop hit Rhythm Nation has been recognized as a cybersecurity vulnerability after Microsoft reported it can crash old laptop computers.

"A colleague of mine shared a story from Windows XP product support," wrote Microsoft blogger Raymond Chen.

The story detailed how "a major computer manufacturer discovered that playing the music video for Janet Jackson's Rhythm Nation would crash certain models of laptops."

Further investigation revealed that multiple manufacturers' machines also crashed. Sometimes playing the video on one laptop would crash another nearby laptop. This is mysterious because the song isn't actually that bad.

Investigation revealed that all the crashing laptops shared the same 5400 RPM hard disk drive.

"It turns out that the song contained one of the natural resonant frequencies for the model of 5400 RPM laptop hard drives that they and other manufacturers used," Chen wrote.

The manufacturer that found the problem apparently added a custom filter in the audio pipeline to detect and remove the offending frequencies during audio playback.
