Second JavaScript Exploit in Four Months Exposes Crypto Sites to Wallet Drainers

2025/12/15 21:38

A newly discovered loophole in one of the web’s most used development tools is giving hackers a new way to drain cryptocurrency wallets.

Cybersecurity researchers have reported a surge in malicious code uploaded to legitimate websites through a vulnerability in the popular JavaScript library React — a tool used by countless crypto platforms for their front-end systems.

Crypto Drainer Attacks Surge via React Flaw

According to Security Alliance (SEAL), a nonprofit cybersecurity organization, criminals are actively exploiting a recently disclosed React vulnerability labeled CVE-2025-55182.

“We are observing a big uptick in drainers uploaded to legitimate crypto websites through exploitation of the recent React CVE,” SEAL stated on X (formerly Twitter). “All websites should review front-end code for any suspicious assets NOW.

The flaw enables unauthenticated remote code execution, allowing attackers to secretly inject wallet-draining scripts into websites. The malicious code tricks users into approving fake transactions via deceptive pop-ups or reward prompts.

SEAL cautioned that some compromised sites may be unexpectedly flagged as phishing risks. The organization advised web administrators to conduct immediate security audits to catch any injected assets or obfuscated JavaScript.

"If your project is getting blocked, that may be the reason. Please review your code first before requesting phishing page warning removal. The attack is targeting not only Web3 protocols! All websites are at risk. Users should exercise caution when signing ANY permit signature."

Phishing Flags and Hidden Drainers

The group warned that developers who find their projects mistakenly blocked as phishing pages should inspect their code first before appealing the warning.

The React development team confirmed on December 3 that it had patched the vulnerability after white hat hacker Lachlan Davidson privately reported the issue.

The fix affects the react-server-dom-webpack, react-server-dom-parcel, and react-server-dom-turbopack packages. The team urged all developers using these components to update immediately.

The Channel Factories We’ve Been Waiting For

The Channel Factories We’ve Been Waiting For

The post The Channel Factories We’ve Been Waiting For appeared on BitcoinEthereumNews.com. Visions of future technology are often prescient about the broad strokes while flubbing the details. The tablets in “2001: A Space Odyssey” do indeed look like iPads, but you never see the astronauts paying for subscriptions or wasting hours on Candy Crush.  Channel factories are one vision that arose early in the history of the Lightning Network to address some challenges that Lightning has faced from the beginning. Despite having grown to become Bitcoin’s most successful layer-2 scaling solution, with instant and low-fee payments, Lightning’s scale is limited by its reliance on payment channels. Although Lightning shifts most transactions off-chain, each payment channel still requires an on-chain transaction to open and (usually) another to close. As adoption grows, pressure on the blockchain grows with it. The need for a more scalable approach to managing channels is clear. Channel factories were supposed to meet this need, but where are they? In 2025, subnetworks are emerging that revive the impetus of channel factories with some new details that vastly increase their potential. They are natively interoperable with Lightning and achieve greater scale by allowing a group of participants to open a shared multisig UTXO and create multiple bilateral channels, which reduces the number of on-chain transactions and improves capital efficiency. Achieving greater scale by reducing complexity, Ark and Spark perform the same function as traditional channel factories with new designs and additional capabilities based on shared UTXOs.  Channel Factories 101 Channel factories have been around since the inception of Lightning. A factory is a multiparty contract where multiple users (not just two, as in a Dryja-Poon channel) cooperatively lock funds in a single multisig UTXO. They can open, close and update channels off-chain without updating the blockchain for each operation. Only when participants leave or the factory dissolves is an on-chain transaction…

BlackRock boosts AI and US equity exposure in $185 billion models

BlackRock boosts AI and US equity exposure in $185 billion models

The post BlackRock boosts AI and US equity exposure in $185 billion models appeared on BitcoinEthereumNews.com. BlackRock is steering $185 billion worth of model portfolios deeper into US stocks and artificial intelligence. The decision came this week as the asset manager adjusted its entire model suite, increasing its equity allocation and dumping exposure to international developed markets. The firm now sits 2% overweight on stocks, after money moved between several of its biggest exchange-traded funds. This wasn’t a slow shuffle. Billions flowed across multiple ETFs on Tuesday as BlackRock executed the realignment. The iShares S&P 100 ETF (OEF) alone brought in $3.4 billion, the largest single-day haul in its history. The iShares Core S&P 500 ETF (IVV) collected $2.3 billion, while the iShares US Equity Factor Rotation Active ETF (DYNF) added nearly $2 billion. The rebalancing triggered swift inflows and outflows that realigned investor exposure on the back of performance data and macroeconomic outlooks. BlackRock raises equities on strong US earnings The model updates come as BlackRock backs the rally in American stocks, fueled by strong earnings and optimism around rate cuts. In an investment letter obtained by Bloomberg, the firm said US companies have delivered 11% earnings growth since the third quarter of 2024. Meanwhile, earnings across other developed markets barely touched 2%. That gap helped push the decision to drop international holdings in favor of American ones. Michael Gates, lead portfolio manager for BlackRock’s Target Allocation ETF model portfolio suite, said the US market is the only one showing consistency in sales growth, profit delivery, and revisions in analyst forecasts. “The US equity market continues to stand alone in terms of earnings delivery, sales growth and sustainable trends in analyst estimates and revisions,” Michael wrote. He added that non-US developed markets lagged far behind, especially when it came to sales. This week’s changes reflect that position. The move was made ahead of the Federal…
