Don’t look now
A new security hole has had folks in the IT industry scrambling lately — it’s a flaw in the way Windows handles a particular kind of image called a Windows Metafile, or WMF. Unlike JPEG images, which are used for detailed images such as photos (they’re called bitmap or raster graphics files), the WMF format is typically used for simpler images (it’s called a vector format).
Whatever. That’s not the point.
Apparently, if you even view an infected WMF file in, say, your e-mail or Web browser, your computer can be hit. Nasty.
And that reminded me of several wonderful stories by David Langford about “Basilisk” images. In short, these are images that, when viewed, overload the human mind to the point of killing a person.
The stories include “Blit,” “Different Kinds of Darkness,” “What Happened at Cambridge IV,” and — not exactly a story — the COMP.BASILISK FAQ.
They’re terrific reading. As you can see by the linked text above, “Blit” and the COMP. BASILISK FAQ are available free online. “Different Kinds of Darkness” was once as well; I’ll try to find a link.
*Neal Stephenson took the idea in a slightly different direction in Snow Crash, in which computer hackers’ minds were destroyed by viewing a particular piece of software.)
