Troy Hunt, a prominent cybersecurity expert and creator of the 'Have I Been Pwned' service, fell victim to a phishing attack that compromised his Mailchimp account. The breach resulted in the export of a subscriber list from his personal blog, which included 16,627 email addresses and associated IP addresses, as well as derived location data such as latitude, longitude, and time zones. Notably, 75% of the affected accounts were already registered in the 'Have I Been Pwned' database. The incident highlights the vulnerabilities even experienced professionals face in cybersecurity, as Hunt was reportedly tricked into clicking a malicious email while experiencing jetlag.
