A US cybersecurity guide outlines how consumers can check whether their Social Security number has been exposed on the dark web and what steps to take if it has. It stresses that a leaked SSN poses risks well beyond fraudulent card charges, as criminals can use it to open new credit accounts, file bogus tax returns, hijack benefits or combine it with other stolen data to commit full identity theft, making prompt, methodical action important rather than panic.

The piece, from Fox News' CyberGuy, recommends checking for signs of exposure, taking immediate remedial steps such as credit freezes and account monitoring, and using ongoing monitoring services to catch misuse early. It also promotes a free live CyberGuy class on 29 August covering bank alerts, stronger logins, phone number protection, credit freezes and safeguarding retirement savings from unauthorised transfers.
