The political world in Westminster is all awhirl because Labour politician Harriet Harman ostensibly sent a tweet to Conservative politician Alan Duncan. Except she did not. A direct message (DM) came to Mr Duncan from Ms Harman's Twitter account, which had been hacked into. She must have received a DM herself, reading something along the lines of "LOL that you?" followed by a dodgy link. Having followed the dodgy link, she will have put her username and password into the boxes and hey presto, her account was hacked.
Rather than making a whole song and dance about it (as the BBC did), prominent Twitter users like Harriet Harman and Alan Duncan should keep abreast of developments on the Internet in order not to fall for hackers like described above.
