When it comes to cyber security, there’s a simple reason why email is the number one threat vector — and will likely remain that way for the foreseeable future. People open emails. All it takes is for one person in the organisation to download an attachment or click on a link that takes them to a website infected with malware for the entire organisation to be impacted.
There are now countless incidents of ransomware requiring organisations to either pay money to cybercriminals to regain access to encrypted files or incur substantial costs recovering data. Most of the time that malware was delivered within an email attachment cleverly crafted using social engineering techniques capable of tricking even the savviest end users into downloading that attachment.
