Binance Co-CEO Yi He’s Account Hack Exposes Critical Security Risks Behind Meme-Coin Manipulation

Social Account Hacked

Yi He’s WeChat account was briefly taken over. The hacker used her identity to send promotional content related to the meme coin MUBARA to her contacts. Notably, as a major Web2 social platform, WeChat maintains strong credibility within the crypto industry, particularly in private-domain communication and internal information flow, giving it significant trust weight — laying the groundwork for the market response that followed.

On-Chain Data Shows Signs of Pre-positioning

Several analytics firms pointed out that two new wallets purchased around USD 19,000 worth of MUBARA hours before the promotion. The token then surged rapidly, at one point rising more than 200%, followed by notable sell-offs at the top, with some profits exceeding USD 40,000. On-chain behavior presented a classic “pre-positioning → information trigger → pump → sell-off” pattern.

Binance and CZ Issued Responses

Changpeng Zhao (CZ) warned users on social media not to trust token recommendations from a compromised account, emphasizing the significant security risks of Web2 platform accounts. The Binance team later confirmed the account had been recovered and issued additional security notices to warn users against fraud, preventing further escalation.

Hijacking Social Identity is Cheaper Than Hijacking Assets

Since social platform accounts are hosted by Web2 companies, their security depends on platform-internal mechanisms. Meanwhile, trust within the crypto industry concentrates heavily on individuals (founders, CEOs, early investors, etc.). This means: A hacker only needs short-term control of a high-trust account to trigger real market behavior.

This “information-entry” risk is becoming a widespread security weak point in the industry.

The Low Liquidity and High Volatility of Meme Coins Amplify the Attack

Meme coins typically exhibit:

• •
  low market cap and extremely cheap manipulation cost
• •
  price driven by investor sentiment
• •
  strong dependence on external narratives and signals
• •
  lack of fundamental valuation metrics

Once a stimulus resembling an “endorsement” appears — even if from a compromised account — prices can swing rapidly. The structural features of meme-coin markets naturally act as an amplifier for this type of attack.

Information Spread Followed a Closed-Trust Chain

WeChat’s private-domain communication has strong trust propagation:

• •
  Information source = a high-profile industry executive
• •
  Information channel = private communication
• •
  Information form = direct forwarding or personal messaging
• •
  Verification threshold = extremely low

In such an environment, many users are prone to interpret this as an “insider opportunity” and quickly follow the signal with trades.

Social Account Security Has Become a New Attack Surface for the Web3 Ecosystem

As the industry matures, the social accounts of project teams, exchange executives, and KOLs have become major information distribution channels for Web3. Compared to smart contracts or exchange security systems, these entry points are far more fragile:

• •
  Web2 platforms rely on passwords and SMS verification
• •
  Lack of on-chain verifiable identity
• •
  No immutability guarantees

Thus, incidents of “account hijacking → market volatility” are almost inevitable in the future.

Speed of Information Transmission and Reaction Creates Tail Risk

The crypto market remains highly asymmetric: Hackers or manipulators sit at the top of the information chain, while regular users remain at the bottom. Market response is propagational, not equilibrium-based.

Thus, even a small time advantage creates a profit window.

Meme Coins Inherently Lack Risk-Pricing Mechanisms

There is almost no fundamental valuation in meme-coin markets — only:

• •
  sentiment
• •
  social signals
• •
  information triggers
• •
  celebrity effects

As long as the narrative is briefly hijacked, prices can deviate sharply from normal levels. Such events are not anomalies but structural consequences of meme-coin markets.

Users Often Make Decisions Based on “Familiar Identities”

Many users did not evaluate token structure, liquidity, or contract security — instead they relied on:

• •
  the message coming from Yi He
• •
  perceived familiarity
• •
  perceived insider opportunity
• •
  urgency

This decision logic is easily exploited by attackers.

Information Verification Is Absent

Many users failed to:

• •
  re-verify sources
• •
  cross-check with official channels
• •
  examine on-chain liquidity
• •
  analyze pool depth
• •
  identify pre-positioning behavior

In a meme-coin environment dominated by young, speculative participants, this risk is magnified.

Retail Investors Are Always the Slowest Reactors

Operator buys → hacker promotes → price pumps → retail buys → operator sells

This is the standard sequence.

Retail investors almost inevitably occupy the final link and thus bear the losses.

Projects and Exchanges Should Establish On-Chain Verifiable Official Announcement Channels

Such as:

• •
  DID binding
• •
  on-chain signature announcements
• •
  decentralized identity authentication
• •
  synchronized multi-platform update mechanisms

This reduces dependency on a single Web2 platform and increases source credibility.

Social Account Security Must Be Part of Industry-Level Risk Management

This includes (but is not limited to):

• •
  enabling stronger verification for executive accounts
• •
  internal multi-layer verification for outbound communication
• •
  isolated management of key personnel’s social entry points

The cost of prevention is far lower than the losses from market volatility.

User Education Must Improve

Teach users to:

• •
  not rely on “familiar-sender” messages
• •
  avoid trusting single screenshots
• •
  avoid chasing pumps in low-liquidity tokens
• •
  not confuse meme coins with insider opportunities

Only when user cognition improves will the attack surface shrink.
