## A few current events

- Remeber [SOPA & PIPA](../../slides/policy.html#/sopapipa)?
  - They tried "site blocking", which was fiercly resisted by just about everybody
  - But site-blocking has become much more common outside of the US
  - Now the music industry is asking for it to be reconsidered in the US
  - Sources: [slashdot article from 11/28](https://tech.slashdot.org/story/18/11/28/0339254/music-industry-asks-us-government-to-reconsider-website-blocking), [torrentfreak article](https://torrentfreak.com/music-industry-asks-us-govt-to-reconsider-website-blocking-181127/)
- And about [Stuxnet](../../slides/stuxnet.html#/)...
  - In early November, it was reported that Iran was hit by a virus similar to Stuxnet but "more violent, more advanced and more sophisticated"
  - Isreal is not commenting on this
  - Little additional information is available; a [Google News search](https://news.google.com/search?q=iran stuxnet) has no news articles in the last few weeks
  - Sources: [slashdot article on 11/2](https://it.slashdot.org/story/18/11/01/2339252/iran-allegedly-hit-by-computer-virus-more-violent-than-stuxnet), [Times of Israel article](https://www.timesofisrael.com/tv-report-israel-silent-as-iran-hit-by-computer-virus-more-violent-than-stuxnet/)
- The [Starwood hotel database hack](https://yro.slashdot.org/story/18/11/30/1425213/marriott-says-500-million-starwood-guest-records-stolen-in-massive-data-breach)
  - 500 million *records* of 327 million *customers* -- and the second largest ever
  - Too early for detailed technical information...
  - How did they get in?  SQL inejection? Phishing attack?  Buffer overflow?  Poor password selection?
  - How long will the CISO (or equivalent) remain with the company?
