Twitter was under fire earlier today as a security flaw sent many users to Japanese porn sites. Some people at work complained about the links not having NSFW warnings but overall (we suspect) not too many tweeters complained about the links. They did share the apparent hijacking with other tweeters however and Twitter kicked in to gear to fix the security flaw.
"It was pretty bad -- we saw it hitting thousands of people a minute," said Graham Cluley, a Sophos technology consultant who was not involved in fixing Tuesday's problem. "The worst we saw was it was redirecting some users to a Japanese porn site."
Overall, Twitter doesn't believe any personal information was compromised so to that we say, "No harm, no foul."
