Yes, with a caveat on the source. The claim comes from a WatcherGuru post at 05:12 UTC Oct 30 saying "North Korea responsible for $6 billion Binance hack, CNN reports."
No CNN page or Binance statement seen so far names North Korea directly. Binance only points to a compromised DevOps laptop, no private key leak, with about $6.3B impacted and about $3B frozen, in its update.
What others cite as behind the CNN line is TRM Labs attributing it with high confidence to TraderTraitor, a North Korea unit, reported as draining about $6.36B across 10 chains in about 20 minutes, per CryptosR_Us and MrWhale.
Onchain support cited is ZachXBT style tracking summarized by WuBlockchain: Binance $6.3B and Bitget $388M funds arrived via THORChain and mixed at the same address, pointing to the same actor. The Bitget case was already linked to North Korea-linked TraderTraitor.
So treat it as: investigators attribute it to North Korea, reported as CNN reporting it, but Binance itself has not attributed the attack.
