Ethereum Classic (ETC) Hit by Double-Spend Attack Worth $1.1 Million

Ethereum Classic (ETC) Hit by Double-Spend Attack Worth $1.1 Million

January 08, 2019Swati Khandelwal
Popular cryptocurrency exchange Coinbase has suspended all transactions of Ethereum Classic (ETC)—the original unforked version of the Ethereum network—on their trading platforms, other products and services after detecting a potential attack on the cryptocurrency network that let someone spend the same digital coins twice. Why is this attack concerning? The heist resulted in the loss of $1.1 million worth of the Ethereum Classic digital currency. The digital currency immediately fell in price after the news came out. Coinbase revealed Monday that it identified "a deep chain reorganization" of the Ethereum Classic blockchain (or 51 percent attack of the network), which means that someone controlling the majority of miners on the network (over 50%) had modified the transaction history. After reorganizing the Ethereum blockchain, the attackers were able to what's called "double spend" about 219,500 ETC by recovering previously spent coins from the rightfu

Again some bad news for cryptocurrency users. KICKICO, a blockchain-based initial coin offering (ICO) support platform, has fallen victim to a suspected cyber attack and lost more than 70 million KICK tokens (or KickCoins) worth an estimated $7.7 million. In a statement released on its Medium post on July 26, the company acknowledged the security breach, informing its customers that an unknown attacker managed to gain access to the account of the KICK smart contracts and the tokens of the KICKICO platform on last Thursday at around 9:04 (UTC). KICKICO admitted that the company had no clue about the security breach until and unless several of its customers fell victim and complained about losing KickCoin tokens worth $800,000 from their wallets overnight. However, after investigating, the company found that the total amount of stolen funds was 70,000,000 KickCoin, which, at the current exchange rate, is equivalent to $ 7.7 million.

Critical RCE Flaw Discovered in Blockchain-Based EOS Smart Contract System

Critical RCE Flaw Discovered in Blockchain-Based EOS Smart Contract System

May 29, 2018Swati Khandelwal
Security researchers have discovered a series of new vulnerabilities in EOS blockchain platform, one of which could allow remote hackers to take complete control over the node servers running the critical blockchain-based applications. EOS is an open source smart contract platform, known as 'Blockchain 3.0,' that allows developers to build decentralized applications over blockchain infrastructure, just like Ethereum. Discovered by Chinese security researchers at Qihoo 360 —Yuki Chen of Vulcan team and Zhiniang Peng of Core security team—the vulnerability is a buffer out-of-bounds write issue which resides in the function used by nodes server to parse contracts. To achieve remote code execution on a targeted node, all an attacker needs to do is upload a maliciously crafted WASM file (a smart contract) written in WebAssembly to the server. As soon as the vulnerable process parser reads the WASM file, the malicious payload gets executed on the node, which could then al

Craig Wright Will Move Satoshi Nakamoto's Bitcoin to Prove His Claim

May 03, 2016Swati Khandelwal
Yesterday, BBC broke a story allegedly revealing Craig Wright as the original creator of Bitcoin digital currency Satoshi Nakamoto. However, the highly skeptical cryptographic community is definitely not yet convinced with the technical proofs Wright has yet provided to the media outlets and on his  blog . Now, Wright has promised to provide further evidence for his claim that he is behind the pseudonym, Satoshi Nakamoto. Wright’s spokesman told BBC that he would " move a coin from an early block " of Bitcoin owned by Nakamoto " in the coming days. " However, the spokesman did not specify a deadline. " So, over the coming days, I will be posting a series of pieces that will lay the foundations for this extraordinary claim, which will include posting independently-verifiable documents and evidence addressing some of the false allegations that have been levelled, and transferring bitcoin from an early block.

Just last month, DARPA launched a project dubbed "Improv," inviting hackers to transform simple household appliances into deadly weapons . Now, the Defense Advanced Research Projects Agency is finding someone in the private sector to develop a hacker-proof " secure messaging and transaction platform " for the U.S. military. Darpa wants researchers to create a secure messaging and transaction platform that should be accessible via the web browser or standalone native application. The secure messaging app should " separate the message creation, from the transfer (transport) and reception of the message using a decentralized messaging backbone to allow anyone anywhere the ability to send a secure message or conduct other transactions across multiple channels traceable in a decentralized ledger, " agency's  notice explains. In simple words, DARPA aims to create a secure messaging service that not only implements the standard encryption and se

A new machine for Bitcoin Mining called " Approximate Hardware " would make Bitcoin mining easier. Bitcoin had gained tremendous popularity over a few couple of years among the virtual currencies due to its decentralized principle. Mining a single Bitcoin is not an ice cake walk, as it requires an enormous amount of computing power to dig Bitcoins. To overcome this issue and mine Bitcoins faster, security researchers has conducted a study and made a new loophole in the mining process in an effort to mine the Bitcoins easily. How to Mine Bitcoins Faster? A team of Illinois-based researchers led by Indian Scientist, Rakesh Kumar, has designed a new hardware named " Approximate " that could reduce the pain of Bitcoin mining by 30 percent. The proposed system would make use of the faults in the hardware system such as: False Positives where an error is not present but notifies a fake error. False Negatives where an error is present but

Some of Bitcoin’s Core developers have left the Bitcoin project and started building their separate cryptocurrency called DECRED . Decred aims to prevent the issues Bitcoin is currently facing regarding project governance and development funding. CEO of ' Company 0 ', Mr. Jacob Yocom-Piatt , who has funded Bitcoin development since early 2013, said the actual development of the Bitcoin cryptocurrency is funded by external entities that forms a conflict of interests between the groups and the project's core developers. According to Bitcoin's developers, these group puts limitations on input in Bitcoin's governance, selecting options that are favorable to their own interests only, and generally ignoring the developers' and project's best interests. "The Bitcoin software is controlled by a small group of people who decide exclusively what can and cannot be changed," Jacob says in a press release . "This is in part due to a la

The Famous Internet entrepreneur and former hacker Kim Dotcom , who introduced legendary Megaupload and MEGA file sharing services to the World, has came up with another crazy idea — To start his very own Internet that uses the "blockchain". Just last month, Kim Dotcom, a German millionaire formerly known as Kim Schmitz , launched the public beta of its end-to-end encrypted video and audio chat service called " MegaChat ", which it says gives better protection than alternatives such as Skype and Google Hangouts. Now, his latest series of tweets referred to Kim Dotcom's supposed " MegaNet " which, he believes, would be immune to the global mass surveillance conducted by governments or corporations and would not be based on IP addresses. MegaNet would be a decentralized, non-IP based network in which the blockchain used by Bitcoin will play an " important role ". Decentralizing the Internet means to take the power of the Web
