According to two persons with knowledge of the situation, a hacking organisation supported by the North Korean government broke into an American IT management company and used it as a launching pad to attack bitcoin companies.

In an effort to steal digital currency, the hackers went into Louisville, Colorado-based JumpCloud in late June and utilised their access to the company’s systems to target its clients who were cryptocurrency companies, according to the sources.

The hack demonstrates how North Korean cyber spies, who were previously content to target individual cryptocurrency businesses, are now attacking businesses that can provide them with access to numerous sources of bitcoin and other digital currencies.
