ASERT has learned of an APT campaign, possibly originating from DPRK, we are calling STOLEN PENCIL that is targeting academic institutions since at least May 2018. The ultimate motivation behind the attacks is unclear, but the threat actors are adept at scavenging for credentials. Targets are sent spear phishing e-mails that lead them to a web site displaying a lure document and are immediately prompted to install a malicious Google Chrome extension. Once gaining a foothold, the threat actors use off-the-shelf tools to ensure persistence, including Remote Desktop Protocol (RDP) to maintain access.
