FBI, U.S. Treasury and CISA Warn of North Korean Hackers Targeting Blockchain Companies

FBI, U.S. Treasury and CISA Warn of North Korean Hackers Targeting Blockchain Companies

April 18, 2022Ravie Lakshmanan
The U.S. Cybersecurity and Infrastructure Security Agency (CISA), along with the Federal Bureau of Investigation (FBI) and the Treasury Department, warned of a new set of ongoing cyber attacks carried out by the Lazarus Group targeting blockchain companies. Calling the activity cluster  TraderTraitor , the infiltrations involve the North Korean state-sponsored advanced persistent threat (APT) actor striking entities operating in the Web3.0 industry since at least 2020. Targeted organizations include cryptocurrency exchanges, decentralized finance (DeFi) protocols, play-to-earn cryptocurrency video games, cryptocurrency trading companies, venture capital funds investing in cryptocurrency, and individual holders of large amounts of cryptocurrency or valuable non-fungible tokens (NFTs). The attack chains commence with the threat actor reaching out to victims via different communication platforms to lure them into downloading weaponized cryptocurrency apps for Windows and macOS, subse

North Korean Hackers Distributing Trojanized DeFi Wallet Apps to Steal Victims' Crypto

April 01, 2022Ravie Lakshmanan
The North Korean state-backed hacking crew, otherwise known as the  Lazarus Group , has been attributed to yet another financially motivated campaign that leverages a trojanized decentralized finance (DeFi) wallet app to distribute a fully-featured backdoor onto compromised Windows systems. The app, which is equipped with functionalities to save and manage a cryptocurrency wallet, is also designed to trigger the launch of the implant that can take control of the infected host. Russian cybersecurity firm Kaspersky  said  it first encountered the rogue application in mid-December 2021. The infection scheme initiated by the app also results in the deployment of the installer for a legitimate application, which gets overwritten with a trojanized version in an effort to cover its tracks. That said, the initial access avenue is unclear, although it's suspected to be a case of social engineering. The spawned malware, which masquerades as Google's Chrome web browser, subsequently
Microsoft Warns of 'Ice Phishing' Threat on Web3 and Decentralized Networks

Microsoft Warns of 'Ice Phishing' Threat on Web3 and Decentralized Networks

February 18, 2022Ravie Lakshmanan
Microsoft has warned of emerging threats in the  Web3  landscape, including "ice phishing" campaigns, as a surge in adoption of blockchain and DeFi technologies emphasizes the need to build security into the decentralized web while it's still in its early stages. The company's Microsoft 365 Defender Research Team called out various new avenues through which malicious actors may attempt to trick cryptocurrency users into giving up their private cryptographic keys and carry out unauthorized fund transfers. "One aspect that the immutable and public blockchain enables is complete transparency, so an attack can be observed and studied after it occurred," Christian Seifert, principal research manager at Microsoft's Security and Compliance group,  said . "It also allows assessment of the financial impact of attacks, which is challenging in traditional Web2 phishing attacks." The theft of the keys could be carried out in several ways, including im
SAILFISH System to Find State-Inconsistency Bugs in Smart Contracts

SAILFISH System to Find State-Inconsistency Bugs in Smart Contracts

January 04, 2022Ravie Lakshmanan
A group of academics from the University of California, Santa Barbara, has demonstrated what it calls a "scalable technique" to vet smart contracts and mitigate state-inconsistency bugs, discovering 47 zero-day vulnerabilities on the Ethereum blockchain in the process. Smart contracts are  programs  stored on the blockchain that are automatically executed when predetermined conditions are met based on the encoded terms of the agreement. They allow trusted transactions and agreements to be carried out between anonymous parties without the need for a central authority. In other words, the code itself is meant to be the final arbiter of "the deal" it represents, with the program controlling all aspects of the execution, and providing an immutable evidentiary audit trail of transactions that are both trackable and irreversible. This also means that vulnerabilities in the code could result in hefty losses, as evidenced by hacks aimed at  the DAO  and more recently,

Google Disrupts Blockchain-based Glupteba Botnet; Sues Russian Hackers

December 08, 2021Ravie Lakshmanan
Google on Tuesday said it took steps to disrupt the operations of a sophisticated "multi-component" botnet called Glupteba that approximately infected more than one million Windows computers across the globe and stored its command-and-control server addresses on Bitcoin's blockchain as a resilience mechanism. As part of the efforts, Google's Threat Analysis Group (TAG) said it partnered with the CyberCrime Investigation Group over the past year to terminate around 63 million Google Docs that were observed to have distributed the malware, alongside 1,183 Google Accounts, 908 Cloud Projects, and 870 Google Ads accounts that were associated with its distribution. Google TAG further said it worked with internet infrastructure providers and hosting providers, such as CloudFlare, to dismantle the malware by taking down servers and placing interstitial warning pages in front of the malicious domains. In tandem, the internet giant also announced a lawsuit against two Russ

Feds Reportedly Hacked REvil Ransomware Group and Forced it Offline

October 23, 2021Ravie Lakshmanan
The Russian-led REvil ransomware gang was felled by an active multi-country law enforcement operation that resulted in its infrastructure being hacked and  taken offline  for a second time earlier this week, in what's the  latest action  taken by governments to disrupt the lucrative ecosystem. The takedown was first reported by  Reuters , quoting multiple private-sector cyber experts working with the U.S. government, noting that the  May cyber attack  on Colonial Pipeline relied on encryption software developed by REvil associates, officially corroborating DarkSide's  connections  to the prolific criminal outfit. Coinciding with the development, blockchain analytics firm Elliptic  disclosed  that $7 million in bitcoin held by the DarkSide ransomware group were moved through a series of new wallets, with a small fraction of the amount being transferred with each transfer to make the laundered money more difficult to track and  convert   the funds  into fiat currency through

Users Can Be Just As Dangerous As Hackers

August 09, 2021The Hacker News
Among the problems stemming from our systemic failure with cybersecurity, which ranges from decades-old software-development practices to Chinese and Russian cyber-attacks, one problem gets far less attention than it should—the insider threat. But the reality is that most organizations should be at least as worried about user management as they are about Bond villain-type hackers launching compromises from abroad. Most organizations have deployed single sign-on and modern identity-management solutions. These generally allow easy on-boarding, user management, and off-boarding. However, on mobile devices, these solutions have been less effective. Examples include mobile applications such as WhatsApp, Signal, Telegram, or even SMS-which are common in the workforce. All of these tools allow for low-friction, agile communication in an increasingly mobile business environment. Today, many of these tools offer end-to-end encryption (e2ee), which is a boon when viewed through the lens of

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. KICKICO reported that suspected attackers

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
