Microsoft reveals Janet Jackson track had the facility to crash laptops - even when it wasn't enjoying on them | Science & Tech Information

The music video for Janet Jackson’s 1989 hit Rhythm Nation was a sensation by way of its choreography and course.

Its foggy noir-like type received it quite a few accolades, together with a Grammy Award for Finest Lengthy Type Music Video.

However the dystopian pop video had one thing else going for it too – the facility to crash laptops based on Microsoft, and never simply people who it was enjoying on.

In a weblog submit this week, the corporate’s principal software program engineer, Raymond Chen, mentioned a colleague had not too long ago shared a narrative with him from the times of offering product help for Home windows XP.

“A significant laptop producer found that enjoying the music video for Janet Jackson‘s ‘Rhythm Nation’ would crash sure fashions of laptops,” wrote Mr Chen.

It was not simply this producer both. The investigation discovered that enjoying the music video additionally precipitated a few of their opponents’ laptops to crash.

However the weirdest discovery was but to come back.

It did not even must be the laptop computer that the music video was enjoying on. Merely enjoying the music video on one laptop computer may trigger one other shut by to crash.

“It seems that the track contained one of many pure resonant frequencies for the mannequin of 5400 rpm laptop computer laborious drives that they and different producers used,” defined Mr Chen.

The problem was just like an opera singer having the ability to shatter a glass by singing a specific tone.

As a result of sounds are merely acoustic waves, there’s a wavelength or frequency for every materials that may create essentially the most vibration, often known as the medium’s resonant frequency.

For the affected laptops – which have been shipped in roughly 2005, based on a vulnerability report filed by The Mitre Company – that frequency was within the Janet Jackson music video.

Mitre describes the problem as a safety vulnerability which may enable an attacker to pressure the system to crash utilizing the audio sign from the Rhythm Nation music video.

Fortunately laptops right now will not undergo from the identical situation – Microsoft says the producer added “a customized filter within the audio pipeline that detected and eliminated the offending frequencies throughout audio playback”.
