The Donot Team threat actor has up-to-date its Jaca Windows malware toolkit with improved capabilities, which includes a revamped stealer module developed to plunder information from Google Chrome and Mozilla Firefox browsers.
The improvements also include things like a new infection chain that incorporates beforehand undocumented parts to the modular framework, Morphisec scientists Hido Cohen and Arnold Osipov disclosed in a report revealed past week.
Also known as APT-C-35 and Viceroy Tiger, the Donot Team is recognised for placing its sights on defense, diplomatic, govt, and navy entities in India, Pakistan, Sri Lanka, and Bangladesh, between other people at least since 2016.
Evidence unearthed by Amnesty Global in October 2021 connected the group’s attack infrastructure to an Indian cybersecurity organization termed Innefu Labs.
Spear-phishing strategies that contains destructive Microsoft Place of work files are the favored supply pathway for malware, adopted by having gain of macros and other identified vulnerabilities in the productivity application to launch the backdoor.
The most current results from Morphisec establish on a prior report from cybersecurity enterprise ESET, which specific the adversary’s intrusions towards military companies primarily based in South Asia using numerous variations of its yty malware framework, a person of which is Jaca.
This involves the use of RTF files that trick customers into enabling macros, resulting in the execution of a piece of shellcode injected into memory that, in transform, is orchestrated to obtain a second-phase shellcode from its command-and-command (C2) server.
The next-phase then functions as a channel to retrieve a DLL file (“pgixedfxglmjirdc.dll” from another distant server, which kick-begins the true infection by beaconing method information to the C2 server, developing persistence through a Scheduled Activity, and fetching the future-phase DLL (“WavemsMp.dll”).
“The key goal of this stage is to down load and execute the modules made use of to steal the user’s information,” the scientists pointed out. “To understand which modules are applied in the recent an infection, the malware communicates with an additional C2 server.”
The C2 area, for its aspect, is obtained by accessing an embedded link that points to a Google Travel document, letting the malware to entry a configuration that dictates the modules to be downloaded and executed.
These modules develop on the malware’s capabilities and harvest a huge variety of info these as keystrokes, screenshots, information, and data stored in web browsers. Also, component of the toolset is a reverse shell module that grants the actor distant obtain to the target machine.
The improvement is yet a different indicator that risk actors are actively adapting their tactics and methods that are most effective in attaining preliminary infection and retaining remote accessibility for extended durations of time.
“Defending from APTs like the Donot crew demands a Protection-in-Depth system that uses multiple levels of security to guarantee redundancy if any given layers are breached,” the scientists said.
