In Web3 security, fake websites, impersonating support agents, and fraudulent projects—known attack vectors—operate alongside emerging types of threats. Binance Wallet security steps in to help you tackle evolving on-chain threats.

In the first half of 2026, the Binance Wallet Security Center Security Center helped users avoid approximately $540 million in potential losses. It runs in the background, scanning in real time the moment you open a link, sign a transaction, or receive an unknown token. When something looks wrong, it alerts you; and when something is clearly dangerous, it blocks it.

In this blog, we’ll break down the 2026 threat landscape, show what the integrated Web3 Security Center does, explore how AI is rewriting the attackers’ playbook, explain how we’re responding, and finally guide you through a ten-second check on your own wallet.

From “spray and pray” to precision hunting

In the first half of 2026, the industry’s biggest security incidents reached the hundreds of millions, and a trend became evident behind many of them: attacks are getting smarter and more deceptive. AI now enables threat actors to generate malicious code in bulk, create video deepfakes of executives to bypass internal approvals, and launch fake sites, identities, and scripts at nearly zero cost.

The incidents below are major security events for projects in the first half of 2026, compiled from CertiK and SlowMist public reports.

While these incidents may seem distant to everyday users, phishing hits much closer to home. According to CertiK’s Hack3D report for the first half of 2026, phishing incidents dropped by more than 50% year over year, but total losses fell by only 10.8%, still reaching approximately $370 million—suggesting that attackers may have shifted from “spray and pray” to precision hunting. ScamSniffer data reinforces this: just in January 2026, approval phishing made 4,741 victims and caused $6.27 million in losses, a 207% month-over-month jump.

What the integrated Binance Wallet Web3 Security Center does

We implement defenses at every stage of the attack chain: we filter traps and junk before they reach you, identify risky transactions at the exact moment you sign, and surface approvals you may have forgotten long ago.

Identify and filter junk and traps

In the first half of 2026, the Binance Wallet Security Center filtered roughly 206 million spam transfers, protecting 2.6 million users. These spam transfers can create different kinds of risk. Some are spam airdrop tokens that try to get you to visit fake sites or interact with malicious tokens. Others are attempts at address poisoning, where attackers insert wallet addresses similar to yours into your transaction history to trick you into copying the wrong address when transferring funds. Even a difference of a single character can send funds to the wrong recipient, and the loss is usually irreversible. The Web3 Security Center continuously identifies and filters these risks from your wallet, delivering a safer, cleaner experience and helping reduce the chance of costly mistakes when transferring funds.

Scam tokens, honeypots, rug pulls, disguised contracts, and phishing domains often set the trap even before you realize it. Binance Wallet security tries to detect these risks earlier, across more networks, and at higher speed. If a threat is detected, a risk alert will appear—giving you one more chance to pause before clicking, signing, or buying.

Identify risky transactions at the exact second you sign

When you tap “confirm,” a single unclear signature or a disguised approval can drain your assets in seconds. In the first half of 2026, Binance Wallet security identified about 4.93 million high-risk transactions across 19 networks. Some were blocked directly by the system, while others were abandoned after users received risk alerts from the Binance Wallet Security Center.

While we can’t block every malicious transaction for you, the Web3 Security Hub uses transaction simulation and security detection to make risks clearer before you confirm. You can see what the transaction will do, how your balances may change, and whether approvals will be granted or modified—helping you spot risks and avoid mistakes before signing.

Bringing up approvals you forgot a long time ago

Often, the real risk isn’t a single transaction—it’s an approval left open for too long. You may have granted permission to a DApp months ago and forgotten about it, but that approval can still expose the assets you authorized. Binance Wallet security brings these long-standing risks back into view, helping users see which permissions should no longer exist. In the first half of 2026, it identified roughly 996,000 malicious approvals.

Attacks are evolving with AI

When comparing the two quarters of the first half of 2026 side by side, there was a significant increase in newly identified malicious entities, including phishing domains, fake tokens, malicious contracts, and malicious addresses. This reflects both stronger detection capabilities and the speed at which new threats multiply. Brand-new threats are being produced in mass at an unprecedented pace, often designed to trick users within minutes after deployment, with AI accelerating how quickly attacks evolve. To stay ahead, Binance Wallet security is using AI proactively to strengthen detection, analyze risk intent earlier, and respond more quickly as attack patterns evolve.

How Binance Wallet security uses AI to detect threats

For a token, we go beyond its code or its status on blocklists and use AI to analyze its behavioral logic and risk intent— including whether it can be bought but never sold, or whether it hides a backdoor that bypasses what users would reasonably expect. For a website, we look beyond how legitimate it seems and use AI to extract risk signals, identifying sites that pose as known projects to trick users into signing approvals. That’s how the P2P “verify your assets” phishing wave was detected in the first half of 2026.

Case study: siphon tokens

Most users assume that as long as they avoid signing approvals or clicking strange links, their funds will be safe. The siphon token case proves otherwise. They’re a class of phishing tokens with backdoors built directly into their contracts, often hidden using deliberately obfuscated code or closed-source contracts that can’t be inspected externally. On the surface, you simply bought a token. Seconds later, that token can be transferred out of your wallet or completely zeroed out—without you granting a single approval.

Figure 3: How siphon tokens work

This type of attack passes conventional checks because it leaves only limited, short-lived signals for detection. Blocklists arrive too late, since these tokens are deployed from disposable wallets, remain active for one or two hours, and then disappear without leaving traces. By the time a full security assessment is completed, the funds are usually already gone.

We detect it by focusing on identifying suspicious behaviors. When a token challenges normal logic, hides a backdoor, or reveals a clear risk intention, we issue an alert as early as possible. The question we ask is what it is, in fact, trying to make users do.

How to protect yourself

At Binance, we’re committed to strengthening every layer of defense, identifying new threats faster, blocking risks more precisely, expanding coverage to more networks, and using AI to track how quickly attackers evolve. But no security system can protect a decision that you insist on making. We can flag a suspicious contract, alert you before a signature, and show exactly which approval looks wrong—but the final decision always belongs to the user. Some attacks, like social engineering, are built exactly for this gap, bypassing the code entirely to target your trust, and that’s why these three habits matter as much as any tool.

  • Understand before signing: if you can’t explain what a transaction does, don’t sign it.

  • Check before you trust (DYOR): confirm whether the person, link, or project is real before you place your trust.

  • Use the [Security Hub]: ten seconds are enough to spot approvals worth revoking or risky assets worth removing. To access it, open the Binance app → [Binance Wallet] → [Settings] → [Security Hub] → [Scan now].

Final thoughts

The first half of 2026 showed that attackers are trading volume for precision, with AI making that precision cheaper. Binance Wallet security responded by filtering roughly 206 million spam transfers, identifying approximately 4.93 million high-risk transactions across 19 networks, and bringing to light nearly 996,000 malicious approvals—helping users avoid approximately $540 million in potential losses. At Binance, your security is our priority, and we’ll continue making detection faster and coverage broader. However, no tool can undo a transaction that you approved. Understand what you’re signing, check before you trust, and set aside ten seconds to scan your wallet in the Binance Wallet Security Hub.
