BGP Peers
HTTP Titles, Response Headers & ETags
X509 Cert Issuers & Subjects & JA4X
JARM
SSH Host Keys & HASSH
Favicon Hashes
OpenDirs
Check out these Infra Trends below 👇

We’ve curated an incredible line up of talks for @BSidesBournemth this year, with a focus on the realities, history, and psychology of ransomware 🔒☣️
You wont want to miss these sessions:

Didn’t realise the GRU were Halo fans 🎮
#APT28 is using weaponized Office documents to deliver the Covenant Grunt backdoor.
We detected a cluster of seven malicious .docm and .xls files between July 8 and July 14, with some having AV detection ratios as low as 5/62 at the time of first submission. Our THOR APT Scanner's YARA rules caught what traditional engines missed.
The documents use obfuscated VBA macros that assemble strings at runtime to evade static analysis, perform XOR-encoded host reconnaissance, and drop a 64-bit Covenant Grunt loader DLL disguised as a log file. The campaign uses Russian-language lures like "Прайс.xls" (Price List) and business-themed filenames like "accounts.xls", consistent with APT28 targeting patterns. Network analysis shows Dropbox being used as C2 infrastructure.
This activity aligns with Zscaler's reporting on Operation NeuSploit (CVE-2026-21509).

This further justifies why ASM tools need to incorporate a way for users to run their own cryptographic bill of materials (CBOM) and why orgs need to start planning to migrate 👇

Me to Scammer: 🫵😂
One of the biggest victims of the Ledger theft was a scammer themselves. They lost more than 60BTC, about $4.8M. The funds were from a task scam.
In this task scam, people were paid to fake sales and reviews of real items. Then a "negative balance" appeared, and they were told to add their own money in order to get paid.
On Sep 22, the person behind the scam moved the proceeds into three separate Ledger addresses. On Oct 9, thieves emptied all three. One transfer each, into the same wallet. The wallet is reported as stolen funds.

The CyberStrikeAI and ARTEX combination by Chinese-speaking offensive actors is an interesting trend we’re following closely 👇
INTEL DROP
AI-native offensive tooling is stacking on single hosts. Total Insights Feed detection pipeline currently sees 1,989 IPs running an AI pentest framework, and 48 of them run two or more. Many share IPs with classic C2, stolen AI API relays, and exposed gen-AI apps. A sample of 8, in the US, China, Hong Kong, Singapore, and Iran:
192.236.166.73 cyberstrikeai + artex + mythic + scopesentry + ai-relay:grok2api
192.253.229.113 cyberstrikeai + artex + pentagi + xingrin
149.104.24.91 cyberstrikeai + artex + arl + ai-relay:sub2api
151.243.126.22 cyberstrikeai + sliver + gen-ai:n8n + gen-ai:openclaw + ai-relay:new-api
103.101.176.236 cyberstrikeai + pentagi + malware-hosting + open-dir
64.20.61.134 pentagi + ai-relay:sub2api + ai-relay:grok2api + open-dir
1.14.104.208 pentagi + adaptixc2 + cobaltstrike
119.45.122.90 deepaudit + gen-ai:ollama + gen-ai:open-webui + gen-ai:openclaw + scanner
Several also expose a Known-Exploited-Vulnerability service (kev-vulnerable) on the same host that runs the attack tooling.
Happy hunting!

*daily double
ARTEX is an open-source autonomous AI pentest platform, multi-agent software that plans attack paths, maps assets, and validates vulnerabilities without an operator. Total Insights has it running on 52 hosts that are also stood up as AI relay stations, the LLM API gateways built on sub2api, new-api, and grok2api. The same boxes proxy model access and run autonomous offensive automation.
ARTEX + ai-relay:sub2api, 40 hosts stepping through two adjacent /24s at regular intervals (United States):

FlowerStorm phishing infra 👇

FlowerStorm phishing, 1,354 domains in the Total Insights Feed, all malicious. The kit is phishing-as-a-service built for adversary-in-the-middle theft of Microsoft 365 logins and MFA tokens. Two naming patterns run side by side.

Most carry low rep TLDs, and the random-suffix names also trip our high-entropy detection process.
