A North Korea-linked cyber-espionage group has been observed leveraging job-themed phishing lures to target prospective victims in energy and aerospace verticals and infect them with a previously undocumented backdoor dubbed MISTPEN. The activity cluster is being tracked by Google-owned Mandiant under the moniker UNC2970, which it said overlaps with a threat group known as TEMP.Hermit, which is also broadly called Lazarus Group or Diamond Sleet (formerly Zinc).
