As Twitter’s user base grows so does the malicious activity on the social networking site. Malicious links spread easily on Twitter as a result of the widespread use of URL shortening services due to its 140 character limit.
In January 2010, Twitter banned 370 passwords for being too obvious, including 123456. As of July 2011, the list has grown to 401 banned passwords. Some of the latest hacked celebrity Twitter accounts include Lady Gaga, Ashton Kutcher, and Kim Kardashian. On September 10, 2011 the NBC News Twitter account was hacked and the perpetrators tweeted that ground zero had been attacked. On September 25, 2011 the USA Today account was hacked.
