Blogged on Labuba RAT: https://cryptax.github.io/posts/labubarat/
My blog post is focused on reversing some anti-analysis features of the malware.
For a general (technical) overview of the malware, read this https://blackpointcyber.com/bl…
maybe I'm wrong about this function. I'm having quite a lot of difficulties understanding it. It just doesn't make sense yet to use gpu/cuda patterns the same way as container/docker/kubernetes. The first ones indicate a real host, the sec…
For example, in here, the malware is crafting a set of regex patterns. Some patterns indicate VMs (eg docker, container).

Currently analyzing a sample of Labuba RAT. There's already an analysis of this here https://blackpointcyber.com/blog/labubarat-a-rust-based-remote-access-tool-masquerading-as-nvidia-software/

If you really insist on "creating malware for science", please pay attention to contain it (air-gapped, strict container), use a void payload (no impact) and present your research in closed conferences with no picture and no recording.
But…
By the way, I personally enjoy this "community service" part of my job : combating malware, and helping - a bit - the population gives sense to my work.
I know that some researchers and hackers will argue that "it's good to know how to cre…
Submitting such a paper is just IRRESPONSIBLE. We, malware analysts and other anti-malware jobs, spend hours trying to secure lives / money of your family, friends, colleagues, companies.
Trying to help malware authors feels like spitting …
I've just been reviewing a paper that explains how to create malware more or less automatically. I won't get into the details of how nor which conference as it's confidential.
It's not the first time I review such papers, and I want you to…
