Danger actors these types of as the infamous Lazarus team are continuing to tap into the ongoing COVID-19 vaccine research to steal sensitive info to speed up their countries’ vaccine-development attempts.
Cybersecurity agency Kaspersky comprehensive two incidents at a pharmaceutical firm and a federal government ministry in September and October leveraging distinct tools and techniques but exhibiting similarities in the article-exploitation system, foremost the researchers to hook up the two attacks to the North Korean federal government-linked hackers.
“These two incidents reveal the Lazarus group’s desire in intelligence associated to COVID-19,” Seongsu Park, a senior protection researcher at Kaspersky, claimed. “While the group is primarily identified for its monetary functions, it is a fantastic reminder that it can go soon after strategic exploration as well.”
Kaspersky did not name the targeted entities but claimed the pharmaceutical agency was breached on September 25, 2020, with the attack against the federal government well being ministry occurring a month afterwards, on October 27.
Notably, the incident at the pharmaceutical company — which is associated in developing and distributing a COVID-19 vaccine — saw the Lazarus group deploying the “BookCodes” malware, a short while ago employed in a offer-chain assault of a South Korean application enterprise WIZVERA to install remote administration tools (RATs) on target devices.
The original obtain vector made use of in the assault continues to be unfamiliar as however, but a malware loader identified by the scientists is claimed to load the encrypted BookCodes RAT that arrives with abilities to gather method info, obtain remote commands, and transmit the benefits of the execution to command-and-manage (C2) servers located in South Korea.
In a separate marketing campaign aimed at the wellbeing ministry, the hackers compromised two Home windows servers to put in a malware known as “wAgent,” and then utilised it to retrieve other destructive payloads from an attacker-controlled server.
As with the earlier scenario, the researchers stated they have been not able to identify the starter module applied in the attack but suspect it to have a “trivial position” of working the malware with distinct parameters, subsequent which wAgent hundreds a Home windows DLL that contains backdoor functionalities instantly into memory.
“Using this in-memory backdoor, the malware operator executed various shell instructions to obtain sufferer facts,” Park stated.
Irrespective of the two malware clusters used in the attacks, Kaspersky said the wAgent malware applied in Oct shared the exact an infection scheme as the malware that the Lazarus team made use of earlier in attacks on cryptocurrency enterprises, citing overlaps in the malware naming plan and debugging messages, and the use of Stability Aid Provider as a persistence mechanism.
The growth is the most recent in a long checklist of attacks capitalizing on the coronavirus pandemic — a trend noticed in many phishing lures and malware strategies all over the past yr. North Korean hackers are alleged to have targeted pharma companies in India, France, Canada, and the British isles-based AstraZeneca.
