Cyber threat actors with ties to North Korea’s government have allegedly broken into the network of German air defense system manufacturer Diehl Defence. According to Der Spiegel, the hackers gained access to Diehl’s network through a spear phishing attack with a malicious PDF attachment that purported to be job offers from US defense contractors. Mandiant investigated the incident and found that the threat actors had conducted reconnaissance prior to the attack.
