Employees in major UK businesses are leaving themselves vulnerable to the most common form of cyber-attack, warns cyber security firm Glasswall Solutions.
Its research shows that office workers in mid-to-large UK businesses are too trusting of email attachments, with 58% regularly opening attachments from unknown senders despite the risk of malicious exploits hidden inside common file-types.
More than four out of five (83%) say they always open attachments that appear to be from a known contact, even though hackers increasingly disguise malicious emails to look as if they have come from someone the recipient knows.
One third (34%) of UK office workers say their business has been victim of a cyber-attack; 76% have received email attachments that were suspicious.
Greg Sim, CEO of Glasswall Solutions, says the vulnerability of email highlights the need for new forms of protection. “Conventional anti-virus and sandboxing solutions are no longer effective and relying on the vigilance of employees clearly leaves a business open to devastating cyber-attacks,” he said.
