Most of Pyongyang’s highest-profile cyberattacks over the past decade were cobbled together with bits of reused code, overlapping networking infrastructure and the indelible fingerprint of North Korean military hackers, a pair of researchers have found. North Korea has come a long way since it first emerged on the global stage as a nascent cyber threat. As it grew in power, hit new targets and conducted malicious activities, Pyongyang didn’t need to reinvent the wheel. Instead, it built on previous successes, leveraging code from previous campaigns to build out future malware. After months of code analysis, Christiaan Beek and Jay Rosenberg, the two researchers, published blog posts outlining their findings, which trace reused code all the way from a DDoS attacks launched by a fledging outfit of North Korean hackers in 2009 all the way to WannaCry, one of the world’s most crippling cyberattacks launched last year by a North Korea-backed hacking group.
