[Ihtesham Ali @ihtesham2005]

A hacker known as "0x90" wanted a way to chat online without anyone tracing who he was. He ended up building a second internet.

It started in 2001 as a small project to let people chat on IRC without anyone tracing who they were.

In 2003, a developer known only by the handle jrandom rebuilt the whole thing from scratch and renamed it I2P, the Invisible Internet Project.

I2P isn't really trying to hide you while you browse normal websites, the way Tor does.

It builds you a second internet that lives entirely inside your regular connection. Inside it are hidden websites called eepsites, hidden chat, and hidden file sharing, all invisible to anyone outside the network.

The trick is something called garlic routing.

Tor wraps a single message in layers of encryption and passes it hop to hop, like an onion.

I2P bundles several messages together into one package before it even leaves your computer, so anyone watching the traffic cannot tell how many separate messages are hiding inside it, or where each one is actually headed.

Tor also uses one path both ways. I2P builds a completely separate path for messages coming in and messages going out, up to seven hops each direction.

There is no company running any of this, and no central server holding a map of the network.

Every computer running I2P is part of that map instead.

In 2006, jrandom, the developer who rebuilt the entire project, disappeared. No announcement. He just stopped showing up.

For a moment it looked like the whole thing might die with him.

It didn't. A group of volunteers, one going by the name zzz, picked the project back up in 2009 and kept building. Twenty three years later, it is still running, still fully open source, still owned by nobody in particular.

[How To Prompt @HowToPrompt__]

Windows has 200+ services running in the background right now.

Most of them exist to collect data on you.

Someone built a free, open-source tool that kills almost every anti-user decision Windows has shipped in the last five years.

Cortana. Copilot. Start menu ads. Telemetry. Location tracking. Suggested apps you never asked for.

Gone. One click. One 8MB .exe.

It's called optimizerDuck. The closest thing to "install Windows the way it should have shipped" I've seen.

→ 35+ optimizations across performance, privacy, GPU, power, services, UX
→ 200+ services you can toggle, each labeled low, medium, or high risk
→ vendor-specific GPU tuning for AMD, NVIDIA, and Intel
→ bloatware remover with a preview of what dies
→ every action gets a rollback file
→ prompts you to make a restore point before touching your system

No installer. No telemetry. No ads. No premium tier.

GPL v3. Runs offline. Windows 10/11 x64.

I just merged one of the most craziest module in CrackMapExec called "hash_spider" from @hackerm00n 🚀

With an initial admin access, it will dump lsass recursively using BloodHound to find local admins path (adminTo) to harvest more users and find new paths until DA 🔥

I'm the next person presenting here: https://t.co/adrJfNAkkr - It's a presentation on Pivoting, and I'll be showing two somewhat new techniques. Setting up a Layer2 VPN over SSH (Tap Addresses) and creating a tunnel over the STDIO of an SSH Connection with socat. Prob 10-15 min

[ippsec @ippsec]

VOD will be up later, but the commands for a layer2 tunnel were:

sudo ssh -o Tunnel=ethernet -w 0:0 [email protected]
ip link add br0 type bridge
ip link set ens160 master br0
ip link set tap0 master br0
ip link set tap0 up (run on both ends)
ip link set br0 up

I graduated with a CS degree from a major university but failed to find a job in tech. For 10 years! I was going to job fairs and applying everywhere. Didn't get anything not even a nibble. Failed. 10 years later I got a CCNA cert and tried again and got picked up right away.
