Operation DRAGONCLONE: Chinese Telecom Targeted by Malware
A sophisticated cyber campaign targeting China Mobile Tietong Co., Ltd., a subsidiary of China Mobile, has been uncovered. The operation, dubbed DRAGONCLONE, utilizes VELETRIX and VShell malware to infiltrate systems. The attack chain begins with a malicious ZIP file containing executable files and DLLs, exploiting DLL sideloading against Wondershare Repairit software. VELETRIX, a loader, employs anti-analysis techniques and IPFuscation to decode and execute VShell, a cross-platform OST framework. The campaign shows infrastructure overlaps with known China-nexus threat actors like UNC5174 and Earth Lamia. The attackers utilize various tools including Cobalt Strike, SuperShell, and Asset Lighthouse System for reconnaissance and post-exploitation activities.

Talking of cool formats:
I was just thinking of Rahul Dhesi's ZOO after posting that, coincidentally.
The format was designed so that backwards seeks were only necessary when actually deleting/updating entries. One could do a list entirely forwards, and even purging deleted entries could be done entirely forwards.
Then the world went and settled on ZIP, which needed several backwards seeks just to find the central directory.
One has to appreciate that #Rust programmers are rediscovering all of these old problems anew almost 40 years later. (-:
So @rl_dane introduced #bzip3 to me to use instead of #bzip2. Let's turn some bz2 files into bz3 to see the difference.
First example: 90k opus files
hey snips wake word dataset. It has ~90k opus files and a tar file of 3.1GB. bzip2 produces the same 3.1GB which is as expected. bzip3 created 3.0GB but used tons of computation power. Not worth the 100MB
Second example: Windows 7 virtual box VM image
Windows7.vdi it's Windows 7 VM image for the "special" days. I think I have to get rid of it. But while it is still there, let's see how each will perform. It is 16GB uncompressed. bzip2 -9 is 7.0GB. bzip3 is 6.3GB but at the expense of like 3x CPU time. Deleting all of them anyway. Down with Windows.
Third example: Pure XML text file
Pure XML file. It's Persian and English characters. Uncompressed is 1.7GB. bzip2 -9 is 276M while bzip3 is 260MB
Final example: Creating a simple bomb
So I did this:
Parental Advisory 
dd if=/dev/zero of=./justzero bs=2G count=6
So now I have a 16GB with only zero bytes. bzip2 -9 is 672KB. bzip3 is 46KB.
Conclusion
Thank you @rl_dane
Real nice thing!

- JSZip: 12 (transitive) dependencies
- tar-js: 0 dependencies
While zip may be more common, the 0-dependencies is a unique selling point for me!
@mavica_again @cstross @NF6X also lets be clear, @NanoRaptor does "Premium" #Shitpost|s or rather "#NextLevel #Memes" to the point that I'd not be surprised if she makes a #NeoFloppy / #Jaz / #Zip mashup and showcases a nonexistant "vintage" portable SSD with like old #ROM chips or #RAM chips...

So after purchasing brand new blank media for my Iomega 250mb ZIP drive, was time to give this disk format tech from 1999 a go on Windows 98!
It's super quiet on file transfers and with my internal drive connected via IDE cable could easily fill a disk within a few minutes.
Impressive stuff!

Here’s some nerdy web tech sorcery: “a file that combines ZIP, HTML, and PNG into one versatile format. It can be displayed as a web page, unzipped to obtain all the page's resources, or viewed as an image.”
