SB169 Does not open an attachment in a message from an unknown source
Opening message attachments from unknown sources (i.e. sources you don't recognise or aren't familiar with) places the company at risk of a cyberattack (e.g. malware).
Why is it important?
Attachments can contain malware. Not opening attachments from an unknown source prevents the potential for an attack.
