The core claim is strongly supported by the fetched article “Drift links $280M hack to radiant attackers,” which explicitly reports that Drift Protocol said the attackers spent six months building trust and posed as a quantitative trading firm before compromising contributor devices. This directly matches the user’s wording about a long-term, organized infiltration lasting about six months. Corroboration comes from the search-result evidence for the WuBlockchain post, which independently repeats that Drift’s investigation described a roughly six-month operation involving attackers posing as a quantitative trading firm, and from the referenced official Drift Protocol X post URL cited by the fetched article. Confidence is medium rather than high because direct fetching of the X posts failed, so the primary official statement could not be fully validated in-page during this run.
