Background for this topic.
Phishing is deceptive communication—by email, text, phone, or a fake website—that impersonates a trusted person or service to make someone disclose credentials, approve a transaction, reveal sensitive information, or run harmful software. Attackers use it to bypass technical controls by persuading a legitimate user to perform an action, and may target employees, customers, administrators, or suppliers.
Its impact can include account takeover, unauthorized payments, exposure of personal or business data, and access to internal systems. The most effective control for stolen-password phishing is phishing-resistant multi-factor authentication, such as hardware-backed passkeys or security keys, which binds authentication to the legitimate site. Organizations should also filter and authenticate messaging where possible, use password managers, restrict risky actions, train users to verify unusual requests through a separate channel, and provide rapid reporting so suspected credentials or sessions can be revoked.
Recently added artificial intelligence capabilities on the Chinese-language Darcula phishing-as-a-service platform make phishing attacks easy for even the least technical hackers.
The losses are 33% higher than the year before, with phishing leading the way as the most-reported cybercrime last year, and ransomware was the top threat to critical infrastructure, according to the FBI Internet Crime Report.
Attackers are using credentials stolen via phishing websites that purport to be legitimate securities company homepages, duping victims and selling their stocks before they realize they've been hacked.
