Quick Answer

From its website , the Department of Homeland Security's (DHS) mission is "to secure the nation from the many threats we face." In essence, the DHS's job is to create trust, for Americans, in their own security. So, it shouldn't come as any surprise that hackers would try to exploit that trust by launching an email phishing scam that impersonates.

From its website , the Department of Homeland Security’s (DHS) mission is “to secure the nation from the many threats we face.” In essence, the DHS’s job is to create trust, for Americans, in their own security. So, it shouldn’t come as any surprise that hackers would try to exploit that trust by launching an email phishing scam that impersonates email alerts from the DHS.

According to the Cybersecurity and Infrastructure Security Agency (CISA), whose parent is the DHS, “The email campaign uses a spoofed email address to appear like a National Cyber Awareness System (NCAS) alert and lure targeted recipients into downloading malware through a malicious attachment.”

Hackers have a pretty simple playbook. Figure out what people trust and exploit that trust to launch an attack. Phishing attacks aren’t about technology, they’re about trust exploitation. So, in that regard, the DHS phishing attack is no different from any other phishing attack.
