Fun research together with @Tera0017. Most reporting so far has been victim side, but we show the agent convos, the hacks and models the ARTEX operators used.
Some obscure chinese grey-market cybercrime stories inside as well :3
Agentic hacking frameworks are on the rise.
We tracked 2,000+ #ARTEX servers and obtained databases with full conversation logs that show exactly how the agents hacked.
It proves: Fully autonomous cybercrime is already here.

We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.
We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵
Blog: rikiyat.github.io/blog/weigh…
Readers added context they thought people might want to know
LLM was given weights explicitly as text in prompt and used code/forward passes (per authors' logs) to ablate Qwen looping direction, a known thinking-mode issue per model card. Primarily fixed repetition in that mode, not general 'natively' improving weights/math.

the cleverer among you can think of ways to use this, a trivial one is to lie to decompilers and lifters.

There’s 100% a kind of mania you can get into with coding agents, where it feels like you’re getting a lot done and working all the time but nothing is really happening.
I think it's often a form of avoidance of something else in life.
#VoltTyphoon operational network for 0-day exploitation uncovered.
Very insightful research from the people
@lumentechco .
Kudos for using the insights on this network over a 3 year timespan to inform victims/targets before major impact.

Just dropped a new blog post! 🔥

In an international law enforcement operation 👮, the US Department of Justice 🇺🇸, in cooperation with private sector partners, have taken down notorious bulletproof hosting provider Virtualine 💥
➡️ justice.gov/usao-edva/pr/bul…
Operating as AS202412 (Omegatech LTD), Virtualine received upstream connectivity from German 🇩🇪 providers aurologic GmbH (AS30823) and Pfcloud UG (AS51396), as well as French 🇫🇷 PEERXY NETWORKS SAS (AS213382), as bgp .tools shows. This network connectivity is now gone, currently making it impossible for Omegatech to operate 🛑
Omegatech announced 24x /24 IPv4 CIDRs, totaling 6,144 IPs. Out of these, hundreds were seen daily participating in spamming, internet-wide scanning, and botnet C2 hosting ⤵️
🌐 URLhaus tracked over 10,000 malware distribution sites at Omegatech: urlhaus.abuse.ch/asn/202412
📡 ThreatFox logged 2,000+ community-shared IOCs tied directly to Omegatech: threatfox.abuse.ch/asn/20241…
The hoster primarily served malicious infrastructure associated with RATs 🖥️ (e.g., PureRAT and OverlordRAT), rogue ScreenConnect servers 🔌, and social engineering malware campaigns like ClickFix and ErrTraffic 🖱️. While internet abuse for sure can happen, Virtualine was not reacting on abuse reports at all and advertised their "bulletproof hosting services" on the darkweb, as investigation shows 🕵️♀️
The takedown of Omegatech is welcome news. However, its long-term impact remains uncertain. Bulletproof hosters commonly re-brand and resume operations under new ASNs quickly 🔃
Furthermore, Omegatech is just the tip of the iceberg. Other active bulletproof hosters include:
➡️ AS219502 (STORMCLOUD)
➡️ AS207043 (DEDIK-IO)
➡️ AS214351 (FEMOIT)
What do they all have in common? According to bgp .tools, they all receive upstream connectivity from German provider aurologic GmbH (AS30823) as well 🔍👀
If you don't want to worry about the threats posed by bulletproof hosters, just block any CIDRs and ASNs listed on @spamhaus 's Don't Router Or Peer List (DROP):

This is absolutely nuts and only hitting German papers so far: leaked emails show that seven politicians from Germany's far-right AfD travelled to Syria to meet with Assad regime officials... facilitated by Hezbollah AND Russian intelligence.

🦠 ThreatLabz has identified an x64 variant of GuLoader. The sample uses similar anti-analysis methods as GuLoader x86 samples. However, the following anti-analysis features have been added:
- Huge stack frames in order to break IDA's decompilation.
- Direct syscalls to call Windows native API functions. GuLoader chooses a different syscall address that is chosen randomly.
- The registered Vectored Exception Handler (used to obfuscate the control flow) points to a location within NTDLL's memory region, making the exception-driven control flow appear legitimate.
- Use of the Windows API function TrySubmitThreadpoolCallback to execute callbacks and avoid detection.
