KyberSwap DEX hacker sends an on-chain message: Be nice, or else

The exploiter behind the $46 million KyberSwap hack says they plan to outline a treaty for the potential return of funds on Nov. 30, but not if threats and hostilities from execs keep up. The exploiter behind the $46 million crypto theft against KyberSwap has demanded its execs and tokenholders ease up on the hostilities, threatening to push out negotiations until everyone is “more civil.” In an on -chain message addressed to KyberSwap executives, tokenholders and liquidity providers on Nov. 28, the exploiter said they plan to release a statement around a potential treaty with KyberSwap on Nov. 30 — but won’t do it if hostilities continue. “I said I was willing to negotiate. In return, I have received (mostly) threats, deadlines, and general unfriendliness from the executive team,” they said. “Under the assumption that I am treated with further hostility, we can reschedule for a later date, when we all feel more civil,” they warned. The @KyberNetwork exploiter sent the team another ...

HTX exchange loses $13.6M in hot wallet hack: Report

The incident affected the greater HTX, Tron, and BitTorent ecosystem. HTX, formerly Huobi Global, suffered an estimated loss of $13.6 million as part of the $86.6 million HECO Chain bridge exploit on Nov. 22.  According to a report by blockchain security firm Cyvers, the losses stem from three compromised hot wallet s with users and exchange assets swapped for Ether and distributed to various Ethereum addresses thereafter. Among other coins and tokens, Cyvers says that 1,240 Ether (ETH), 7.3 million Tether (USDT), 1.78 million USD Coin (USDC), and 62,200 Chainlink (LINK) were drained during the attack.  Justin Sun, de-facto owner of HTX and founder of Tron and BitTorrent, both related entities, stated shortly after the exploit that "HTX Will Fully Compensate for HTX's hot wallet Losses. Deposits and Withdrawals Temporarily Suspended. All Funds in HTX Are Secure, and the Community Can Rest Assured." Earlier in the day, the HECO Chain bridge, a cross-chain bridge created...

Fantom Foundation awards $1.7M bounty for preventing $170M drain

Image
In the aftermath of Fantom’s $550,000 hack in October, a security researcher found that the attacker could have stolen as much as $170 million. The Fantom Foundation, a nonprofit organization developing the Fantom blockchain platform, has eliminated a significant vulnerability after a $550,000 hack in October. On Oct. 17, the Fantom Foundation suffered a hot wallet hack, with an unknown attacker drain ing 1% of Fantom Foundation’s funds. The foundation subsequently stopped using some of the affected wallets, reassigning them to a Fantom employee, making it a “targeted attack.” Following the incident, an unnamed security researcher found an additional potential risk associated with the hack and alerted the Fantom Foundation, according to a blog post on Nov. 20. The vulnerability was associated with a dormant admin token for Fantom’s ERC-20 FTM contract, which could potentially allow the attacker the ability to mint a portion of Fantom (FTM) for themselves on Ethereum. According to the ...

Atomic also argued that only one user in Colorado was allegedly affected — which wasn The firm also claimed the 5,500 allegedly affected Atomic users agreed to its terms of service which expressly disclaims liability for losses due to theft and limits damages to $50 per user Atomic’s motion to dismiss the class action laid against them.

ConsenSys releases ‘fuzzing’ tool to test smart contract vulnerabilities

Image
Diligence Fuzzing lets developers introduce random and invalid data points to find security flaws. Blockchain technology firm ConsenSys publicly released its “Diligence Fuzzing” tool for smart contract testing, according to an Aug. 1 announcement. The new tool produces “random and invalid data points” to find vulnerabilities in contract s before they are launched. Over $2.8 billion was lost in decentralized finance hacks in 2022. According to ConsenSys, these losses are leading developers to embrace more sophisticated testing tools to help find vulnerabilities before attackers do. The new tool used to be available in a closed beta version, where developers needed to get approval for access. This approval process is no longer necessary as of Aug. 1. Diligence Fuzzing is also now integrated with smart contract toolkit Foundry and Features a free version for developers who want to test it out before spending any money.

What is ethical hacking, and how does it work?

Ethical hacking is the practice of identifying and testing vulnerabilities in a system to improve its security and prevent unauthorized access. Ethical hacking, also known as “white hat” hacking, is the process of identifying and exploiting vulnerabilities in a computer system or network in order to assess its security and provide recommendations for improving it. Ethical hacking is done with the permission and knowledge of the organization or individual that owns the system being tested. Ethical hacking aims to find flaws in a system before malevolent hackers may take advantage of them. The same tools and methods used by malevolent hackers are also used by ethical hackers, but their objective is to enhance security rather than cause harm. Here’s how ethical hacking typically works. Planning and reconnaissance The target system or network is investigated by the ethical hacker in order to acquire data that could be utilized to find weaknesses. This could consist of information such as ...
