Blockchain analytics company Chainalysis said on Friday it was targeted in a cybersecurity incident, similar to those recently suffered by other platforms, Cointelegraph reported.

The company found no evidence of unauthorised access to investigation content, authentication credentials, or session tokens, according to Cointelegraph. However, some non-sensitive customer data was exposed.

Chainalysis engaged world-class third-party cybersecurity experts to support a review of its security. The firm is also using large language models to strengthen its defences.

The company clarified that the security incident was not related to the recent $6.3bn crypto theft at Binance, Cointelegraph said.

Chainalysis has recently focused on tracking illicit crypto flows. It reported on X on Friday that suspected North Korea-linked hacks accounted for almost 89 percent of reported crypto hack losses this year, up from 15 percent in 2021, Cointelegraph said.

YourKhabri earlier reported on 30 October that Binance founder Changpeng Zhao called the $6.3bn hack a major disaster for the industry. Tether froze $971m in USDT linked to the security breach on 29 October, YourKhabri said.
