In the April security roundup, ESET Chief Security Evangelist Tony Anscombe highlights three major cybersecurity developments affecting organizations and individuals. The first involves a surge in Microsoft Teams helpdesk impersonation scams, where attackers exploit external collaboration features to trick users into providing remote access to their systems.
The report also addresses a critical alert from U.S. federal agencies concerning Iranian-linked hackers targeting Rockwell programmable logic controllers (PLCs) found in U.S. critical infrastructure. Finally, the summary notes the FBI IC3's annual report, which indicates that cyber-enabled crimes resulted in nearly $21 billion in losses last year, highlighting the massive financial scale of current digital threats.
