and it is already being used by attackers. This issue is putting many websites at risk including crypto related platforms. The danger is real and active and it affects sites that have not been updated.

The problem is known as React2Shell. It is tracked as CVE 2025 55182. This flaw allows attackers to take control of a server from a distance without any login. That means no password is needed. Once inside they can run their own code freely. This is one of the worst types of security problems.

React developers shared the issue in early December and marked it as very severe. Soon after that security teams saw attackers using it in real attacks. Both money driven groups and advanced hacker groups were involved. They targeted websites running affected React and Next js setups.

React Server Components are used to move some work from the browser to the server. This helps sites run faster and smoother. But the way React handles incoming requests had a weakness. Attackers can send a special request that tricks the server. The server then runs commands chosen by the attacker.

The affected versions are React 19.0 to 19.2.0. Many websites use these versions without knowing the risk. In many cases just having the package installed is enough to be attacked. No extra action is needed from the site owner.

Attackers moved fast after the issue became public. Some started using it within days. One common attack was placing mining software on servers. This software quietly uses system power to mine crypto for the attacker. The website owner pays the cost through slow systems and higher bills.

Other attacks were more dangerous. Hackers placed backdoors on servers. This allows them to return later anytime. Some attacks focused on crypto related sites. These sites often use React and Next js for user actions like wallet connections and transaction approval.

When a site like this is hacked the danger moves to users. Attackers can change the site code. They can add bad scripts that watch wallet actions. They can change where transactions go. A user may think they are sending funds normally but the funds could be redirected.

Even if the blockchain itself is safe the front end can still be used against users. Browser wallets trust what they see on the screen. If that screen is controlled by an attacker users are exposed.

This makes front end security very important. Many people focus only on smart contracts or networks. But a weak website can be just as dangerous. One bad click or one signed action can cause loss.

Website owners using React should act fast. Updating to safe versions is critical. Checking servers for strange activity is also important. Waiting increases risk every day.

For users caution is also needed. Avoid using sites that look strange or act slow. Stay alert during wallet actions. Security starts at the surface where people interact.

This incident is a strong reminder. Modern tools bring speed and ease. But they also bring new risks. Keeping systems updated and simple awareness can make a real difference.

Ethereum co-founder Vitalik Buterin has introduced a bold idea that could transform how social media platforms operate. His proposal uses zero-knowledge proofs (ZK proofs) to verify that algorithms behave according to declared rules — without exposing sensitive data or proprietary code.
The idea emerged from a broader debate on algorithmic amplification, coordinated online manipulation, and the responsibilities of platforms that brand themselves as defenders of free expression.
The discussion was sparked by comments from David Crapis of the Ethereum Foundation, who argued that platforms committed to free speech should at least disclose the optimization goals behind their algorithms.

Vitalik took this further:

every ranking, recommendation, or engagement-weighting decision could be backed by a ZK proof, ensuring correctness without revealing internal logic.

ZK Proofs as a Framework for Algorithmic Accountability
Under Buterin’s model, platforms would generate cryptographic evidence showing that algorithmic outputs follow predetermined goals.
He proposes recording key metadata on the blockchain, such as:
the time content is created,timestamps of interactions,and related contextual data,
to reduce the risk of shadow censorship, downranking, or retroactive content manipulation.
To protect intellectual property, Vitalik suggests delaying the release of full algorithmic code by one to two years, allowing audits without immediate exposure to security risks.
The discussion gained momentum after Buterin commented on what he described as coordinated attacks against Europe taking place on major social platforms.

He warned that if a platform positions itself as a global champion of free speech while simultaneously allowing widespread coordinated harassment, it could provoke long-term backlash against open discourse itself.
Participants also pointed to the rising threat of automated amplification — especially AI-driven botnets capable of generating enormous volumes of synthetic engagement.

As one participant noted:
“More speech is not always the cure when harmful narratives are being pushed by machines.”

Combining ZK Proofs With Other Cryptographic Systems
Vitalik didn’t limit his ideas to social media. He also suggested layering ZK proofs over other cryptographic tools, including:
MPC (multi-party computation)FHE (fully homomorphic encryption)TEE (trusted execution environments)
He highlighted voting systems as a key use case, where anonymity and resistance to coercion are crucial for blockchain-based governance.

ZK-based voting models are already gaining momentum among privacy-focused communities, and a multi-layered cryptographic architecture could mitigate the risks that arise when these tools are used in isolation.

Adoption Is Accelerating: ZK Tech Reaches Tens of Billions
Zero-knowledge technology has expanded rapidly. By 2025:
more than $28 billion in value was locked in ZK-based protocols,major institutions including Goldman Sachs, Sony, and Deutsche Bank adopted ZK rollups for secure transactions, NFT verification, and compliance workflows,ZK rollups processed over $100 billion in stablecoin transactions, driven largely by USDT and USDC.
Vitalik’s own technical work played a major role. His GKR protocol code streamlined verification of complex computations and enabled everyday users to run full nodes on standard hardware.

Conclusion: ZK Proofs Could Define the Future of Responsible Algorithms
Vitalik’s proposal has drawn significant attention because it blends:
transparency,privacy protection,cryptographic accountability,
into a single coherent framework.
If adopted, this approach could usher in a new era of social platforms where algorithms cannot act in the shadows — and users finally understand what drives their feeds.
