US and South Korean agencies have issued a joint cybersecurity advisory describing the tactics, techniques and procedures used by North Korean hackers to deploy "State-sponsored" ransomware on hospitals and other organizations that can be considered part of the countries' critical infrastructure. "The authoring agencies assess that an unspecified amount of revenue from these cryptocurrency operations supports DPRK national-level priorities and objectives, including cyber operations targeting the United States and South Korea governments-specific targets include Department of Defense Information Networks and Defense Industrial Base member networks," the advisory points out.

North Korea has hit a new low, using the death of over 150 people to exploit a zero-day flaw in Internet Explorer. South Korea declared a week of national mourning after the incident.

The North Korea-linked ScarCruft group has been attributed to a previously undocumented backdoor called Dolphin that the threat actor has used against targets located in its southern counterpart. "The backdoor has a wide range of spying capabilities, including monitoring drives and portable devices and exfiltrating files of interest, keylogging and taking screenshots, and stealing credentials from browsers," ESET researcher Filip Jurčacko said in a new report published today.

The infamous Lazarus Group has continued its pattern of leveraging unsolicited job opportunities to deploy malware targeting Apple's macOS operating system. In the latest variant of the campaign observed by cybersecurity company SentinelOne last week, decoy documents advertising positions for the Singapore-based cryptocurrency exchange firm Crypto.com.

The North Korea-backed Lazarus Group has been observed targeting job seekers with malware capable of executing on Apple Macs with Intel and M1 chipsets.

Microsoft researchers have linked an emerging ransomware threat that already has compromised a number of small-to-mid-sized businesses to financially motivated North Korean state-sponsored actors that have been active since last year.
