Lost+Found: Olympic Wi-Fi police, Pentagon porn ban and Black Hat slides

Too short for news, too good to lose; Lost+Found is a round up of useful security news. This time: the police seem to be clamping down on unauthorised hotspots at the Olympics, US missile defence staff are no longer allowed to watch porn while on duty, and hackers build an EXEPDFJARHTML file.

• Bloomberg reports that the Pentagon's missile defence staff have received a memo warning them not to access pornographic content from their office – among other things because this can compromise system security and wastes working time. The report doesn't say anything about cat-related content.

Using a smartphone to create a Wi-Fi network (tethering) is also prohibited. You think that no-one will notice? Think again: it's monitored by the Wi-Fi police. One argument against this being a joke is that the strange arrow appears to be an actual directional antenna by Rohde & Schwarz that serves for locating the source of Wi-Fi signals.

• A hacker has built a file that is an EXE file (Windows Portable Executable), a PDF document, a Java archive (JAR) and an HTML page all at the same time. Why? Because he can. And to demonstrate that file identifiers not starting at offset 0 are a bad idea.
  

• The director of the Atomic Energy Organisation of Iran (AEOI), Fereydoun Abbasi, has denied the alleged AC/DC attack on Iranian nuclear facilities that was in the news last week.
  

• Slides from the Black Hat conference are now available online.
