Escalating global cyber threats require robust, layered security measures

Research routinely exposes the rapidly changing email-based threat landscape and its innovative tactics, as malicious actors relentlessly shift tactics and seek out human and software vulnerabilities with crafty, innovative attacks.

The latest analysis of more than 1.8 billion emails in the first quarter of this year shows that the US is the largest source of spam emails, followed by Britain, Ireland and Japan. This is a change from the corresponding period in 2023, when, in addition to the US, Germany and Turkey were also the dominant sources of spam emails. Furthermore, it appears that the countries the spam comes from are also the same as their targets. The US, UK and Canada are the top three countries most exposed to email attacks. The reasons could be socio-economic factors or simply that cybercriminals are changing course as vigilant companies keep pace with their turf-targeting schemes.
