A North Korean state-sponsored hacking group often called Lazarus is once more attempting to hack safety researchers, this time with a trojanized pirated model of the favored IDA Professional reverse engineering utility.
IDA Professional is an utility that converts an executable into meeting language, permitting safety researchers and programmers to investigate how a program works and uncover potential bugs.
Safety researchers generally use IDA to investigate authentic software program for vulnerabilities and malware to find out what malicious habits it performs.
Nonetheless, as IDA Professional is an costly utility, some researchers obtain a pirated cracked model as an alternative of buying it.
As with every pirated software program, there’s all the time the danger of it being tampered modified to incorporate malicious executables, which is exactly what ESET researcher Anton Cherepanov found in a pirated model of IDA Professional distributed by the Lazarus hacking group.
Trojanized IDA Professional targets safety researchers
This IDA installer has been modified to incorporate two malicious DLLs named idahelp.dll and win_fw.dll that shall be executed when this system is put in.
The win_fw.dll file will create a brand new process within the Home windows Job Scheduler that launches the idahelper.dll program.
The idahelper.dll will then hook up with the devguardmap[.]org web site and obtain payloads believed to be the NukeSped distant entry trojan. The put in RAT will enable the menace actors to realize entry to the safety researcher’s machine to steal recordsdata, take screenshots, log keystrokes, or execute additional instructions.
“Primarily based on the area and trojanized utility, we attribute this malware to identified Lazarus exercise, beforehand reported by Google’s Menace Evaluation Group and Microsoft,” ESET tweeted relating to connection to Lazarus.
Cherepanov advised BleepingComputer that whereas he doesn’t know the way the installer is being distributed, it was found just lately and seems to have been distributed since Q1 2020
Lazarus has a historical past of concentrating on researchers
The Lazarus hacking group, additionally known as Zinc by Microsoft, has a protracted historical past of concentrating on safety researchers with backdoors and distant entry trojans.
In January, Google disclosed that Lazarus conducted a social media campaign to create pretend personas pretending to be vulnerability researchers.
Utilizing these personas, the hacking group would contact different safety researchers about potential collaboration in vulnerability analysis.
After establishing contact with a researcher, the hackers would ship Visible Studio tasks associated to an alleged ‘vulnerability,’ which contained a malicious hidden DLL named ‘vcxproj.suo.’
When the researcher tried to construct the mission, a pre-build occasion would execute the DLL, which acted as a customized backdoor put in on the researcher’s machine.
Different Lazarus attacks also used an Internet Explorer zero-day to deploy malware on safety researcher’s gadgets once they visited hyperlinks despatched by the attackers.
Whereas it was by no means decided what the last word aim was for these assaults, it was prone to steal undisclosed safety vulnerabilities and exploits that the hacking group might use in their very own assaults.
