Sea Turtle is a Türkiye-linked threat actor active since at least 2017 performing espionage and service provider compromise operations against victims in Asia, Europe, and North America. Sea Turtle is notable for targeting registrars managing ccTLDs and complex DNS-based intrusions where the threat actor compromised DNS providers to hijack DNS resolution for ultimate victims, enabling Sea Turtle to spoof log in portals and other applications for credential collection.1234

Reading and review
Records are auto-ingested and not human-reviewed. Confidence is the writer's 0–100 value; bands split at ≥80 / 50–79 / <50 into high / medium / low. The four trust axes (synthetic, lifecycle, band, source count) stay separate and never merge into one score.
