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.[1][2][3][4]

Standing G1041
Reach is how much of ATT&CK this group touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 176 ATT&CK groups only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
Reach
Techniques2761st pct
61st percentile · 61% of 176 ATT&CK groups have this many Enterprise techniques or fewer.
Tactics1059th pct
59th percentile · 59% of 176 ATT&CK groups have this many tactics spanned or fewer.
Tool or malware1Bottom 23%
23rd percentile · 77% of 176 ATT&CK groups have more tools and malware.
Campaigns089% tie · 4 values
89% of the population shares a single value across only 4 distinct values, so a percentile here would rank the tie, not the entity.

Detection coverage G1041
627 distinct rules cover the 27 techniques recorded for this group. The 725 technique-to-rule mappings resolve to 627 distinct rules, because one rule can cover several techniques. 398 Sigma · 229 Splunk.
