🚨 Vishing Attacks Target Salesforce: Why Human-Centric Security is More Critical Than Ever

In a concerning development for enterprise security, cybercriminals are increasingly targeting Salesforce implementations through sophisticated vishing (voice phishing) attacks. The threat actor group UNC6040 has been particularly active, using social engineering tactics to manipulate employees into authorizing malicious Salesforce-connected apps—leading to data breaches and subsequent ransom demands.

The Evolution of Social Engineering

What makes these attacks particularly dangerous is their focus on human vulnerability rather than technical exploits. Instead of attempting to breach Salesforce's robust security infrastructure, attackers are impersonating IT support staff and using psychological manipulation to convince employees to grant access to sensitive systems.

This shift in tactics highlights a crucial reality: your technical defenses are only as strong as your human firewall.
