Unconfirmed reports suggest insurers could start cracking down on customers who post too much personal information online.
An online security firm's director says he expected insurers to change their rules in the next year so that they can refuse to pay out if they believe posts on sites such as Facebook have made it easier for them to be burgled or scammed.
Oliver Crofton of Vigilante Bespoke told the Daily Mail of one case where a man posted a photo of his car where both the license plate and tax disc expiry date where legible. That was enough for scammers to send him a bogus e-mail purporting to come from the DVLA and trick him into installing malicious software that could uncover his bank details and passwords.
Other risks include users posting details of when they were going away on holiday, having previously revealed where the lived, leaving them open to burglaries.
Insurers don't currently take online posts into consideration when checking a claim unless there is clear evidence of gross negligence. However, a spokesman for comparison website Confused says insurers might begin searching online for such posts as part of their standard claims assessment procedures.
