In the last article: “Blockchain Attack Vectors & Vulnerabilities to Smart Contracts” we reviewed all known attacks on the blockchain, in this article we will talk about crypto threats again and we will talk about identifying vulnerabilities for Cold wallets, as well as for Hot wallets. Blockchain is the underlying tech layer made up of a decentralized…

</p> In this article, we will talk about all known attacks on the blockchain, as well as smart contract vulnerabilities. Blockchain isn't really as secure as we tend to think. Though security is integrated throughout all blockchain technology, even the strongest blockchains come under attack by modern cybercriminals. Blockchains can resist traditional cyber attacks quite well, but…

In this article, we have compiled a list of useful tools and services for tracking illegal activities, crypto threats, and finding vulnerabilities in blockchain transactions. Most of the services include a comprehensive hack monitoring platform and process algorithm for the security of crypto wallets. In cryptanalysis, the control and analysis of transactions is always important to us. These services are…

In this article, we will take a detailed look at the open source password recovery tools and wallet seed phrases in the Crypto Deep Tools repository, and we will also discuss the situation when you accidentally lost or forgot part of your mnemonic or made a mistake while decrypting it. (So you either see an empty wallet…

In this article, we will tell you about the most daring and biggest thefts of cryptocurrencies associated with платформой DeFi. Hackers had a big year in 2021 when they stole $3.2 billion worth of cryptocurrencies. But in 2022, the amount of theft of cryptocurrencies reached a historical maximum. In the first three months of this year, hackers have stolen $1.3 billion from…

This article will focus on a vulnerability in inter-network bridge protocols, which is a big security threat to smart contracts between different blockchains. Cross bridges are an attractive target for hackers because they often represent a central storage point for the funds that support the "bridge" assets on the receiving blockchain. What are Internet Bridge Protocols? Bridges…

In this article, we will again touch on the topic of a signature failure in a blockchain transaction and apply a completely new attack: “WhiteBox Attack on Bitcoin” .Differential fault analysis (DFA)was briefly described in the literature in 1996 when an Israeli cryptographer and cryptanalyst Eli Biham and an Israeli scientist Adi Shamir showed that they could use error injection to extract the secret key and recover the private…

In this article, we will compile a complete list of cryptocurrency exchange hacks, starting with the most recent major hack of the Binance exchange , where hackers stole tokens BNBtotaling $ 570 million, and ending with the Mt. Gox, which during the period from 2010 по февраль 2014 годовwas the world's largest cryptocurrency exchange Bitcoinand serviced 80%transactions. This whole cyclic process of hacks is due to user data leaks . Cryptocurrency…

The biggest cryptographic strength of the Bitcoin cryptocurrency is a computational method in discrete mathematics that takes the problem of factorization of large integers and the problem of hidden numbers (HNP)in the Bitcoin signature transaction as a basis ECDSA.In this article, we will apply Signature Fault Differential Analysis ECDSAand derive a private key from a transaction for five different Bitcoin Wallets.Rowhammer Attack…

On the web, you can find a lot of controversy regarding the hacking of Bitcoin Wallets. The result of the discussion is the selection of two main ways: by gaining access to the PC of cryptocurrency owners and through the selection of private keys (с помощью личных данных пользователя). Bitcoin and other cryptocurrencies traditionally attract increased attention хакеров of various calibers,…
