Jenny Radcliffe is probably the only person in the world who has secretly entered the Tower of London carrying smoke bombs, lock-picking keys, a large hammer and 12 different, highly convincing identity documents.

Bypassing security was pretty easy. When the guard helping to rush her to a speaking engagement inside the Tower asked to check her bag, she ‘accidently’ spilt her water bottle on the interesting part of his trousers. When she started trying to brush him dry with her hands, the guard stepped back blushing and waved her through. When Radcliffe told the story at ITWeb’s Security Summit, she had the audience in stitches. She also had free access to one of London’s most historic sites, armed with pretty serious criminal equipment, breaching the defences with nothing more technical than a water bottle.
