A long-running phishing campaign known as Operation HookedWing has targeted over 500 organizations across various sectors for more than four years, resulting in the theft of 2,000 user credentials. The campaign has adapted its tactics and infrastructure while maintaining a focus on high-value targets, using phishing emails that impersonate legitimate communications and direct victims to fake Microsoft Outlook login pages.
Operation HookedWing's use of GitHub domains and compromised servers to execute a persistent phishing campaign highlights the critical need for organizations to bolster their defenses against sophisticated phishing tactics. To mitigate such threats, focus on implementing robust email filtering, continuous phishing simulation training for employees, and advanced threat intelligence monitoring to detect and respond to evolving phishing techniques targeting high-value credentials and sensitive information.
