The FBI and the Department of Homeland Security have released an alert saying the government of North Korea appears to have been using a malware to home in on telecommunications, finance and aerospace sectors since 2016, ZDNet reported Tuesday.
The FBI and DHSâ U.S. Computer Emergency Readiness Team said in the alert issued Tuesday that they identified internet protocol addresses and other threat indicators linked to the Fallchill malware.
Fallchill is a remote administration tool that infects a victimâs computer through the use of fraudulent Transport Layer Security communications and multiple proxies to obscure network traffic.
The agencies labeled North Koreaâs network intrusion activity as âHidden Cobraâ that can potentially have âsevere impactsâ such as loss of proprietary data, disruption to operations, financial losses and potential harm to an institutionâs reputation.
DHS urged administrators and users to adopt measures to protect computer networks from the malware and those include the use of application whitelisting to block malicious software and installation of latest software patches.
