Cybercrime has cost organisations more than £5 million in the past 13 months*, with employees being tricked into downloading malware that looks like it comes from IT support, among other phishing scams.
Among the most common types of phishing seen are employees being tricked into downloading malware that looks like it comes from IT support, clone login pages stealing personal details, and emails containing fake alerts from common workplace software.
A new single-click ‘Report Phishing’ button now allows people to report suspicious emails directly to the National Cyber Security Centre (NCSC).
People can already forward scams to the NCSC’s Suspicious Email Reporting Service (SERS), but having a button directly inside Outlook is a lot easier for people to use and will hopefully result in more widespread use of the service.
