How US SOCs and MSSPs Can Use Threat Intelligence to Detect Phishing Infrastructure Earlier

Phishing remains one of the most persistent problems for security teams, as the challenge is no longer limited to identifying suspicious emails. Behind a single malicious link there may be a newly registered domain, a compromised website, a redirector, a phishing kit, a credential-harvesting page, or infrastructure used by several related campaigns. Attackers can also rely on legitimate cloud services and authentication mechanisms, making individual pieces of the attack look less suspicious on their own. For US-based SOCs and MSSPs, that creates a visibility problem. Blocking a known phishing URL is useful, but it does little for the next URL the attacker registers. Investigating one malicious domain is useful too, but the real question is whether that domain is connected to other infrastructure already targeting the organization.
