Many people ask me how to learn to conduct on-chain investigations. Indeed, often knowing the tools alone isn’t enough. You also need to know certain techniques and methods.
And you can read about them completely free of charge on the FBI’s website. Let’s take this case as an example.
Unraveling the "Razzlekhan" Labyrinth (The Bitfinex Hack)The Case: The laundering of 119,754 stolen Bitcoin from the 2016 Bitfinex exchange hack.
Written by a Special Agent, this document exposes the bizarre dual life of Ilya Lichtenstein and Heather Morgan. It details how they used automated transaction scripts and darknet markets to "chain hop" tokens, contrasted against the traditional search warrant that found private keys hidden in their cloud storage.

P.S. For those who want to learn about the tools as well, below I’ll list a few of my favorite tools for on-chain investigations.

Dear followers, there are only a couple of days left to support the projects in the Giveth x TheDAO grant.
Link to the projects: https://qf.giveth.io/qf/ethereum-security
Donations starting from just $1 will work here! But it’s very important to first check your score on app.passport.xyz - and if it’s above 20, you can add the projects to your cart (this is important: you need to donate only through the cart, not directly to the address) and support them.
Before donating, please do this first (this is for people that never donated on giveth):
1. Click Check eligibility 2. Click Go to app.passport.xyz 3. Connect a wallet you actually use 4. Complete the quick check 5. Go back to Giveth, click refresh score, then donate 6. Click Add to Cart and finish the donation from the cart.
I recommend supporting projects that haven’t received many donations this year, as well as backing a variety of projects from the curated lists (for example, those from ZachXBT).
I’d also be really happy if you support my own grant - it will let me write more articles and release DeFi Roadmap 2.0.
Link to my grant page: https://qf.giveth.io/project/opsec-hub?roundId=16
Thank you!

Urgent: Update iOS Now — A Dangerous Vulnerability Found in Safari and Chrome Browsers.
Apple has released an emergency update for iOS 18.6 to address a serious security vulnerability. Hackers are already exploiting it — simply visiting a website can trigger the malicious code. There's no need to download anything.
What’s particularly concerning is that all iPhones starting from the XS model are at risk. Attackers can gain access to passwords, banking information, and even enable hidden surveillance.

Researchers from kaspersky Lab have shared the results of their investigation into an incident involving a blockchain developer who fell victim to a scam.
It turned out that a fake extension for the Cursor IDE code editor infected devices with remote access tools and info stealers, which led to the theft of $500,000 in cryptocurrency from the mentioned developer.

A victim just lost over $101K USDT by sending funds to a fake address, spoofed within the transaction history by scammers.
Victim: 0xff275bdd99c64c02e305504eaa36a6e9d90b20b4
📚 How Does the Attack Work?
The scammer sends "dust" or a worthless token to your wallet from an address that looks very similar to the one you frequently send funds to. The attacker deliberately chooses an address with the same beginning and end as your usual recipient's address (for example, an exchange). As a result, when copying the address from the transaction history, the user is highly likely to select the fake one.
📚 Why is the Attack Effective?
The fact is that users often:
🔹 Copy addresses from history in blockchain explorers (e.g., Etherscan); 🔹 Make a test transaction, which only reinforces the fake address in their history; 🔹 Do not use built-in protective tools in wallets, such as an address book.

Three Good Multisig Operations Tips!
You can create multisig with Safe, and sign transactions off-chain and send them using any other wallet that doesn't control multisig at all. So, you could use Safe contract alternatively to any ERC2771 smart contracts (like Openzeppelin Defender is).
How to choose a better number of signers? Pick a M-of-N multisig where M is less than N, such as 2-of-3. Give yourself some leeway, a 2-of-2 requires all your backups to work perfectly.
Implement Web3 Front-end monitoring, use a tool by @koda (link below)!

A victim lost $510,294 due to copying the wrong address from transaction history!
Victim: 0x0d534863a71d5e68d5c919a4c2ef47c3a7a792c0
Fake address: 0x4049Ebf479Fa49924e120490d119f0827cAa9aeC
Legitimate address: 0x40491fe2bA81621475c894Ebe8bcad56C7da9aec
How transaction history poisoning works:
1. Scammer sends fake/dust transfer with similar address; 2. Their fake address appears in your history; 3. You copy address from history thinking it's legitimate; 4. Funds get sent to scammer instead.
How to stay protected:
1. Always double-check the addresses you're sending funds to; 2. Never copy addresses from transaction histories; 3. Use a wallet that supports whitelisting or bookmarks.

RustBlockSec: Part I
\ \ RustBlockSec | Part 1One\ \ Rust, developed by Mozilla in 2010, is a safe and productive programming language that is gaining popularity in system programming. It boasts impressive speed and strict memory safety through ownership and borrowing mechanisms, which prevent errors like data races and memory misuse. The cargo package manager aids developers in creating crates, running tests, and generating documentation. Although it is not entirely memory leak-proof, it significantly reduces such risks. It provides lifetime checking, frees memory automatically, and offers an Option type for handling missing values. The active developer community contributes to its growth with new libraries and tools, making it attractive to developers of various levels. It offers a systematic approach to understanding Web3 security, thanks to the Rust Security builders and community. Therefore, what follows is not a typical article, but a systematization of knowledge (SoK)! Let's get started!](https://mirror.xyz/0xc34B1730BA53abD717a1E57A358F39C046053581/DLhgR1FqmKdTZyzxilIzykRCIGzEe0lgkhf6VYvnv-E)
