Attackers Don't Just Send Phishing Emails. They Weaponize Your SOC's Workload

The most dangerous phishing campaigns aren’t just designed to fool employees. Many are designed to exhaust the analysts investigating them. When a phishing investigation takes 12 hours instead of five minutes, the outcome can shift from a contained incident to a breach. For years, the cybersecuri...
