A North Korea-linked APT group, tracked as Andariel Group, leveraged an ActiveX zero-day vulnerability in targeted attacks against South Korean entities.
According to a report published by South Korean cyber-security firm AhnLab, the Andariel Group is a division of the dreaded Lazarus APT Group, it already exploited ActiveX vulnerabilities in past attacks
The attackers exploited at least nine separate ActiveX vulnerabilities, including a new zero-day flaw, in a wave of watering hole attacks aimed to infect visitors of compromised websites with a backdoor trojan.
The zero-day vulnerability seems to be connected to a series of attacks against Samsung SDS Acube installations.
Acube is an application developed by Samsung’s enterprise division widely used in South Korean enterprises that supports ActiveX controls to implement interactive features.
“According to the security industry, from late last month until this month, attacks against North Korean research institutes and websites have been spotlighted.” reported the local media DDaily.
“The attacker, who is believed to be carrying the Andaleri Group, exploited about 9 ActiveX vulnerabilities, including Samsung SDS “eCube”, and tried to collect information through a water ring attack.”
The malicious code was used to control the infected systems and gather intelligence.
“The zero-day vulnerability has been found in this attack, but it is unclear whether the attacker actually used it,” said a government official from the Korea Internet & Security Agency (KISA).
