What should I do now?
In this order, for what this breach exposed.
1. Assume your messages can be read
- Think about what you wrote on KomikoAI and who it names. Warn anyone whose details you shared.
- If someone threatens to publish what you wrote unless you pay, do not pay. Keep the messages and report it to your local police.
2. Expect phishing
- Be wary of messages that urge you to act fast, ask for personal details, or link to an address that is slightly off.
- If a message might be genuine, do not use its links or phone numbers. Go to the site by typing its address yourself.
