Microsoft: North Korean hackers targeted vulnerability researchers in an attempt to steal information via a backdoor. Microsoft says it started tracking the campaign by this North Korean-linked group in mid-2020. Microsoft also says the hackers may have exploited zero-day vulnerabilities in Windows and Chrome. The hackers started by building a reputation in the security research community through Twitter by retweeting and posting high-quality security content. Microsoft stresses that anyone who visited one of the hacker-controlled domains should run a scan of their device to look for indicators of compromise and malware.”]
