Hackers suspected of ties to North Korea's Lazarus Group identified 30 servers in South Korea as potential cyberattack targets in October, according to a report released by cybersecurity firm Cyfirma. The firm said Korean-speaking hackers compiled a list of 216 servers across 10 countries, covering government agencies, banks, telecommunications companies and infrastructure providers. The new findings revise the earlier characterization of the activity as confirmed targeting through PHP vulnerabilities.
