Attribution evidence file

Who has been blamed for the attack, by whom, and on what stated basis. Every entry is one party's statement, quoted and archived: each line links to its statement page, which holds the quote, the capture time and the hash of the stored copy. This site makes no attribution of its own, and quoting a statement here does not adopt it.

How to read this page. Parties are listed with government sources first, then analytics firms, then everyone else. The columns and lists below are assigned by keywords in each claim's one-line summary, so a claim can be placed in a column a reader would not have chosen, and can appear in more than one. An empty cell means no approved claim was matched to it by those keywords. It does not mean the party has no such basis, and a basis stated in words the keywords miss would not show here.

Group names (and the aliases one party gives them) are the names used by the party that stated them. Where sources use the names differently, that is shown under disagreements.

75 approved statements read, from 20 parties; 15 statements about earlier incidents; 0 flagged conflicts.

When each attribution was published

Approved timeline rows in the attribution category. The times come from different clocks and different kinds of source (a post, a blog entry, a notice that gives only a date), and they are not reconciled here.

Basis not public, or not recorded

Two lists. The first is statements in which a source itself says the basis for an attribution is not public. The second is parties whose attribution statements are recorded here with no claim matched as a stated basis.

Caveats and doubts from the sources

Statements, attributed to whoever made them, that qualify an attribution or say none has been made. They are listed as stated and are not weighed against the attributions.

Public commentary, labelled as theory

2 labelled statements

Comments from public forums, recorded with status theory. They are opinions, not evidence, and are not counted as any party's position.

Earlier incidents named in the sources

Two things are kept apart. First, notices and firm reports about earlier incidents, quoted from their own pages and dated before this incident. Second, statements about this incident that compare it with earlier ones. A comparison is the source's own, and similarity is not shown here as proof.

Theories about attribution

Theory Open

The North Korea attribution is wrong or premature

Some firms and commenters raised doubts about attributing the theft to North Korea's TraderTraitor group. Before the FBI statement, Hacken wrote "None of this is proof" and pointed to what it calls "the most careful reading", an Elliptic analysis it links, as explaining why. The passage lists a small overlap with funds from the Bitget theft and a slower pace of conversion than it said North Korean groups usually show. On Hacker News, two commenters suggested North Korea was a convenient or politically attractive target to blame.

Assessment on the theory page: On 31 October the FBI said North Korea was responsible and named TraderTraitor. TRM Labs, Chainalysis and Elliptic reached the same view earlier. They cite the on-chain link to Bitget funds, the preparation, and methods similar to the Bybit theft. The reasons for caution in Hacken's text, which credits an Elliptic analysis it links as the most careful reading, were written before the FBI statement. The FBI statement we captured does not set out its evidence. In the sources captured as of 2026-11-01, the two Hacker News comments give no evidence for another actor. In the sources captured as of 2026-11-01, Binance has not published its root cause. Hacken wrote that "that firm", the Elliptic analysis it links, calls this "the most diagnostic fact still missing". As of 2026-11-01 the weight of captured public attribution points to North Korea, with technical questions still open.

Theory Unsupported

Was an insider involved? Commenters' question, no evidence reported

No source captured as of 2026-11-01 reports evidence that an insider was involved, and no investigator or official in those sources has said so. Some Hacker News commenters asked whether the theft was an inside job, and one wrote that it was almost certainly an inside job given the knowledge of Binance systems the attack needed. This is speculation by commenters.

Assessment on the theory page: Commenters point to the knowledge of Binance systems the attack needed. Binance's co-CEO said the investigation has not attributed responsibility to any individual. The FBI says North Korea's TraderTraitor group is responsible. We found no source, in the sources captured as of 2026-11-01, that reports evidence of knowing insider involvement. In the sources captured as of 2026-11-01, Binance has not yet published its post-mortem, so how the attacker obtained the signatures is not public. We do not identify or comment on any individual.
