Main cryptocurrency news for the morning of May 13

In mid-May 2025, the cryptocurrency exchange Coinbase Global ( ticker COIN) will officially join the S&P 500 index. The platform will replace the shares of Discover Financial Services, which was acquired by Capital One Financial. This was announced by S&P Global on May 12.

The inclusion of Coinbase in the index means that its shares will be accounted for in the portfolios of millions of index funds and ETFs tracking the S&P 500.

The S&P 500 index reflects the dynamics of the 500 largest public companies in the USA. It is "weighted" by market capitalization: the largest participants (Microsoft, Apple, Nvidia) carry the most weight, while companies at the bottom of the list, including Coinbase, typically account for about 0.01–0.2% of the index.

After the announcement of Coinbase's inclusion in the index, COIN shares rose by almost 9% in after-hours trading, and the company's market capitalization exceeded $50 billion.

The team behind the DeFi protocol Curve Finance has revealed information about a new attempt to hijack its DNS. On May 12, a warning appeared on the project's official account on X stating that the domain curve.fi "points to an improper IP address" and redirects users to a fraudulent site.

The Curve team assured that the smart contracts and two-factor authentication remain secure, and that the issue is already being discussed with the registrar; however, user operations on the site may lead to a loss of funds.

At the same time, Blockaid recorded suspicious activity on the frontend of Curve. According to analysts, this could be a repeat frontend attack in which attackers substitute interface elements to steal data or transaction signatures.

Users are strongly advised not to sign transactions and to completely refrain from interacting with DApps until full control over the DNS is restored.

On the night of May 13, the official accounts of ZKsync and Matter Labs on X (formerly "Twitter") were compromised. The attackers posted a fake statement claiming that an investigation was allegedly opened against the platform by the U.S. Securities and Exchange Commission (SEC) and that the Treasury Department might impose sanctions.

At the same time, hackers sent out links to a fake airdrop, urging users to interact with a malicious site. Matter Labs quickly regained control over the accounts and confirmed that the message about the SEC investigation is completely unrelated to reality.

The attack led to a short-term decrease in the price of the ZK token (ZKsync) by approximately 2% within an hour after the publication. Over the course of a day, the token fell by 6.4%, retreating from a nearly 38.5% seven-day increase.

A representative of Matter Labs stated that the hack most likely occurred through "delegated" accounts with limited access, which allowed the attackers to post on behalf of the team.

This is already the second incident involving the compromise of ZKsync in the past two months: on April 15, a hacker exploited administrative access to the airdrop contract and temporarily minted 111 million ZK tokens.

Recall that earlier the BeInCrypto editorial staff reported that Ethereum stakers are once again in profit amid the rise in the cryptocurrency's exchange rate.
