That's the equivalent of 1.9 social network profiles 'smugged' every second.
Credit card provider Capital One has compiled the social media mugging report to explore the depth of the growing 'smugging' trend.
The firm claims as increasing numbers of Britons sign up to social networks, 91 per cent of victims were smugged via Facebook, which counts for 16 per cent of all Facebook users in the UK.
Nine per cent of Twitter users and seven per cent of LinkedIn users also experienced the same problem over the past 12 months, according to the report.
Results show ‘friends’ as the most common smugging culprits at 36 per cent, while 21 per cent comes from distrusting partners snooping around to gather information without consent.
It was also revealed that one in ten claim their ex-partner has infiltrated at least one of their accounts.
29 per cent of smuggers gain access by others not logging out of their computer, while 15 per cent gain access via mobile phone, though just five per cent say their account has been hacked intentionally.
Smugging victims don't seem to learn from past mistakes as the average profile is accessed 9.9 times per year. This leaves 43 per cent of smuggers to use the opportunity to post a false status, 25 per cent to send a message to contacts and 24 per cent to change personal details.
Michael Woodburn, CMO, Capital One, said: "Social networking sites are a great way to stay in touch with friends and family. Yet in the excitement of connecting with those around us, remembering to protect your online profile can often take a back seat, which can leave people open to smugging, or worse, identity theft.
"Small actions like protecting your mobile with a password, using a password that is a combination of numbers and letters and regularly checking bank and credit card statements, can go a long way in helping people protect themselves against a smugging attack and identity theft."
Further results show there are repercussions as over 30,000 people have been reprimanded at work and more than 18,000 claim they’ve been excluded for promotion because of smugging.
