How Does Safeheron Tackle "What You See ≠ What You Sign" Anatomy of Bybit & Safe’s breach

1. Bybit Incident Latest Summary Update

On Feb 21, 2025, at 22:13 Singapore time, Bybit’s treasury team initiated a cold-to-warm wallet transfer using Safe{Wallet}’s multi-signature workflow during which attackers manage to exploit the process and successfully steal $1.4 billion in assets.

On February 26, 2025, Sygnia released the findings of its investigation, confirming that the AWS S3 bucket of Safe{Wallet} had been compromised by hackers who deployed malicious JavaScript code targeting Bybit. The primary objective of this code was to alter transaction details during the signing process. Meanwhile, Safe{Wallet} has stated that its smart contracts remain unaffected.

2. The Root Vulnerability: “What You See ≠ What You Sign”

The Bybit breach exemplifies the fatal gap between displayed intent and executed action — a flaw inherent to many wallet architectures:

A. Infrastructure Compromise
If attackers hijack a wallet’s UI/backend, users may unwittingly approve malicious transactions masked as legitimate.

B. Ecosystem Compatibility Issues

The ByBit breach highlights a critical flaw in ecosystem compatibility: even with secure devices like Ledger, the lack of seamless integration between systems can undermine security. In this case:

• Safe’s UI Was Compromised: Attackers manipulated the displayed destination address, making it appear legitimate.
• Ledger’s Offline Verification Fell Short: As the final line of defense, Ledger failed to effectively implement "what you see is what you sign" due to poor compatibility with Safe’s UI. It only displayed contract interaction parameters and failed to show the complete transaction details. 

Smart contract based solutions like Safe{Wallet} excel at key fragmentation but may not fully address transaction integrity verification, highlighting the need for enhanced security measures tailored to institutional use cases. This incident underscores the importance of adopting robust multi-layered solutions to safeguard against sophisticated exploits in high-stakes environments.

3. The Solution: How Safeheron Ensures "What You See = What You Sign" 

Safeheron’s military-grade security architecture — MPC (Secure Multi-Party Computation) + TEE (Trusted Execution Environment) + Policy Engine — is engineered to prevent such attacks at every layer:

Layer 1: Policy Engine Block Non-whitelisted Transfers at the Pre-Approval Stage
Transfers to Whitelisted Addresses: Safeheron’s Policy Engine enables institutions to restrict transfers exclusively to pre-authorized addresses, ensuring non-whitelisted transactions are automatically blocked before they even reach the approval stage.

Threshold Rules: Multi-tiered approvals, time locks, and volume caps mitigate human error or insider threats.

Layer 2: TEE & Multi-Signature Protect Whitelist Integrity
With safeheron, whitelisted addresses can only be added or modified through multi-party consensus, removing single points of failure. Real-time tampering detection within TEE triggers instant alerts if unauthorized changes are attempted, ensuring the whitelist remains secure.

Layer 3: TEE Guarantees "What You See Is What You Sign"
Every transaction is hashed, signed, and validated within Intel SGX-secured TEE. Tamper-proof attestation reports ensure that the UI-displayed data (recipient, amount) exactly matches the on-chain execution, eliminating discrepancies between intent and action.

Conclusion

Safeheron's design philosophy assumes that even if internal personnel act maliciously or the system is compromised by hackers, as long as the Safeheron App and Co-Signer function correctly, Safeheron cannot steal user keys or transfer customer assets. To this end, Safeheron confines risk exposure to the customer-side App and Co-Signer, as well as the platform-side Co-Signer and TEE (Trusted Execution Environment), ensuring that the customer side possesses independent "What You See Is What You Sign" capabilities and TEE verification functions. Even if the Safeheron server is entirely compromised, customer assets remain secure. 

Furthermore, Safeheron rigorously adheres to the DevSecOps principle, ensuring system security through secure App and Co-Signer build environments and stringent approval and verification processes.

4. Institutional Wallet Security: Why Architecture Dictates Survival

The Bybit incident is not an anomaly but a referendum on wallet design:

Safeheron redefines institutional security with institutional-grade safeguards:

1. No Single Failure Layer: MPC key shards;TEE ensures what you see is what you sign; policies enforce rules.
2. Zero Blind Spots: Every transaction is cryptographically tied to human-verified intent.

By integrating advanced cryptographic techniques and decentralized governance, Safeheron provides a comprehensive security framework that addresses both external and internal threats, setting a new standard for institutional asset protection.

Security is not a feature — it’s a discipline. Safeheron is committed to ensuring your treasury’s survival in the age of infinite attack vectors. In an age of increasingly sophisticated cyber threats and ever-proliferating attack vectors, safeguarding digital assets has become paramount. Safeheron steadfastly adheres to a zero-trust security framework, continuously refining technologies and defense mechanisms to deliver a robust and reliable shield for asset protection. No matter the challenges, we remain by your side, ensuring the security of every transaction.
