State of Web3 Security 2024: Solving the $2B Hacking Crisis with Next-Gen Innovation
Discover how Web3 security battles $2B in 2024 losses through phishing, key breaches, and cutting-edge solutions like the Credible Layer by Phylax System
Introduction
The Web3 security landscape in 2024 presents a stark paradox: while blockchain technology promises trustless systems and immutable security, the industry continues to face sophisticated attacks resulting in substantial losses.
In the first three quarters of 2024 alone, attackers have extracted over $2 billion in digital assets through various exploit vectors, highlighting the persistent gap between theoretical security models and their practical implementation.
Current State Analysis
The attack surface has evolved significantly, with Q1 2024 recording $826,205,224 in losses across 67 incidents, followed by $512,928,000 in Q2, and $463,594,618 in Q3.

This trajectory reveals two critical insights:
The average magnitude of successful attacks has increased, despite a decrease in total incident count
The recovery rate of stolen funds has dropped to a concerning 4.1% in Q3, down from 14.4% in Q2
Fig. 2: Year-wise total number of hacks vs amount stolen
As shown in the chart above, in 2024, stolen funds grew by 21.07% YoY to $2.2 billion, with hacking incidents rising from 282 in 2023 to 303 in 2024.
Apart from that, the ecosystem was on pace to match the $3 billion+ records of 2021 and 2022 by the end of July. However, growth slowed significantly after July and has since leveled off.
Primary Attack Vectors in 2024
Two dominant attack vectors have emerged as the most financially devastating:
Phishing Attacks: $343,099,650 stolen (65 incidents)
Sophisticated social engineering targeting private keys
Compromised front-end interfaces
Malicious contract approvals
Private Key Compromises: $324,000,000 stolen (10 incidents)
Direct wallet breaches
Infrastructure vulnerabilities
Compromised key management systems
Evolution of Attack Sophistication
The technical sophistication of attacks has increased dramatically since early Web3 vulnerabilities. Modern attacks frequently combine multiple exploit vectors and leverage complex smart contract interactions.
Historical Context
The DAO hack (2016), the first major smart contract vulnerability, caused over $50 million in losses and prompted the industry to adopt code audits and governance reforms.
Parity Multisig Hack (2017), a critical vulnerability in the Parity Multisig Wallet (v1.5+), allowed an attacker to exploit the initWallet function and reinitialize wallet ownership. The attacker took control of the wallet and stole over 150,000 ETH by forwarding unmatched function calls using delegatecall. This incident highlighted the risks of poorly secured library patterns, the need for stricter access control, and a safer smart contract architecture.
The Ronin network hack (2022) resulted in a $625 million loss due to the compromise of the network's multisig validator mechanism, where attackers gained control of five out of nine validators.
Euler Finance (2023), an advanced flash loan attack that resulted in $196 million in losses, showed how sophisticated attackers were becoming.
The DMM bitcoin exploit (2024), which resulted in a $305 million loss due to access control issues, exposed the shortcomings of the current security measures.
Current Technical Vulnerability Landscape
Web3 has faced persistent threats since its inception, and many of the early attack vectors are still relevant today. Exploits like stolen private keys, price oracle manipulation, malicious insiders, input validation issues, broken access controls, flash loan attacks, reentrancy, and misconfigurations still remain major vulnerabilities in the ecosystem.
These flaws are frequently caused by a combination of poor privilege management, flawed contract logic, and insufficient testing procedures.

Recent Innovations in Web3 Security
The growing complexity of decentralized systems has prompted the creation of numerous new security solutions. Some of the key innovations in this space include:
Next-block Mitigation & Front-running Protection:
The goal of these mechanisms is to stop attackers from taking advantage of predictable transaction behaviors. By concealing transaction details or building blocks that prevent malicious transactions from mining first, it offers vital protection against front-running and related exploits.
Fuzzing & Client-Side Monitoring:
Fuzz testing has become a crucial tool for smart contract security, involving the use of random or unexpected inputs to uncover hidden vulnerabilities. However, it is important to note that fuzz testing is compute-intensive, requiring significant processing power to explore a wide range of potential edge cases effectively.
Additionally, client-side monitoring has proven highly effective in identifying potential issues in contract interactions with clients, allowing developers to address problems proactively before they escalate.

How Formal Verification Prevents Bugs
Formal verification is crucial to Web3 security, as shown by the recent compiler-level bug affecting Aave on ZKSync Era. Formal verification tools like Certora helped find the problem's root cause: it was caused by a small optimization flaw in the LLVM compiler that created an incorrect bitmask dimension. This led to incorrect behavior in bit manipulation operations.
A "magic value," which is a constant value, was hardcoded in the compiler's optimization routine and caused the bug. This value, which is a 64-bit constant mask meant to clear certain bits, was used incorrectly in the 256-bit ZK-EVM environment. Because the higher-order bits were set to zero in the wrong way, lower-bit flags were cleared during bitwise operations without meaning to.
This example demonstrates how formal verification enables deep, low-level analysis, which traditional testing methods frequently overlook.
Modern Security Solutions and Innovation
Competitive Audit Landscape
Platforms like Code4rena, Sherlock, and Cantina are gaining traction by offering pre-deployment security audits, where security researchers review code before it is made public. Together, these platforms have helped uncover over 1600 high-level bugs, over 30,000 unique findings, and secured billions of dollars.

Regulation as a Catalyst for Security & Growth
Over the past few years, regulatory agencies like the Financial Action Task Force (FATF) have been examining the crypto industry more closely and have called for stricter compliance regulations. The group has set global standards that all countries must follow. These standards are similar to the rules that govern traditional financial systems.
For instance, the travel rule necessitates the recording and sharing of information about the source and destination of crypto transactions, a task that can prove challenging in decentralized environments.
As a result, many cryptocurrency service providers are now regarded as risky by banks and financial institutions, and they frequently face difficulties in obtaining essential services. The FATF and other regulatory bodies require these providers to implement rigorous anti-money laundering (AML) and counter-terrorism financing (CTF) protocols. While these regulations improve security and trust in the crypto ecosystem, they also pose significant challenges for decentralized platforms that have traditionally operated outside of conventional regulatory frameworks.
Ultimately, addressing security concerns preemptively will increase the velocity of innovation within the crypto space. Firms that demonstrate a commitment to asset protection and regulatory compliance are likely to see accelerated growth and acceptance in mainstream financial markets.
Moving Towards Verifiable Security
In today's world, users can only check social media sites like Twitter, Telegram, Discord, or Reddit to find out if the protocol they are using has been hacked. This lack of transparency makes users vulnerable and unaware of potential threats to their funds and data. This is where verifiable security measures play a crucial role in ensuring that users can independently verify the security and integrity of the protocols they interact with. This is how it appears in real life:
1. Cryptographic Proofs
Transaction integrity is validated by zero-knowledge proofs.
State changes are confirmed by Merkle proofs.
Formal verification of critical protocol components.
2. Transparent Security Layers
Example: Modern Bridge Architecture
Before: "Trust our validators."
After:
Light client verification
Fraud proofs
Decentralized validator sets
Cryptographic attestations
3. Built-in Verification Mechanisms
Time-delayed upgrades
Multi-signature requirements
On-chain governance
Public audit trails
The "Don't Trust, Verify" Framework
Blind trust is greatly reduced when verifiable security is incorporated directly into protocols, creating a culture of do not trust but verify. This strategy strengthens the foundation of transparency and trustworthiness while also improving the overall security framework. Thus, it attracts retail and institutional players who demand higher digital asset security standards.
Modern protocols should enable users to verify:
Current system state is accurate.
All changes follow protocol rules.
Admin actions are constrained and transparent.
Protocol changes are predictable and verifyable.
Steps to implement verifiable security
For developers:
Document all trust assumptions explicitly
Implement verification mechanisms at protocol level
Provide tools for users to validate security claims
Build time delays into sensitive operations
For users:
Question protocols lacking verification mechanisms
Use available tools to validate security claims
Understand the trust assumptions they're accepting
Prefer systems with built-in verification
The Security Arms Race
Web3 security is an ongoing battle between attackers and defenders. Attackers are always coming up with new ways to get around increasingly sophisticated defenses.
The adaptation cycle looks like this:
Attack→ Defense→ Innovation→ New Attack Vector
This cycle serves as an example of an important reality: security is a process of constant adaptation rather than a final destination.
Redefining Proactive Security with Credible Layer
Proactive security in Web3 demands a shift beyond traditional methods and tools. While AI and machine learning have their place, the real prevention lies in fundamentally rethinking the integration of security into blockchain systems.
This is where the Credible Layer emerges as a groundbreaking solution, tackling vulnerabilities at the base layer rather than the application layer.
The Credible Layer operates by enforcing provable assertions that define what constitutes a hack for each protocol. The block-building process validates these assertions, ensuring the detection and removal of malicious transactions before execution.
Unlike conventional security measures that rely on reacting to threats, the Credible Layer embeds protection directly into the infrastructure, enabling:
Hack Protection at the Source: Assertions added to the block validation process by block builders are the main defense against exploits. This stops exploits before they can affect the network.
Transparency and Trust: Every assertion is publicly verifiable, enabling protocols and users to validate security measures independently without relying on centralized authorities.
Economic Incentives: Staking and rewards incentivize security researchers and block builders, fostering an ecosystem that aligns economic interests with robust security.
This provable and embedded security model not only addresses immediate vulnerabilities but also builds a foundation of trust and reliability for dApps, protocols, and users alike.
By creating safer blockspace, the Credible Layer transforms security from a reactive afterthought into a proactive guarantee, enabling the blockchain ecosystem to scale with confidence.
Looking toward the next evolution of Web3, the Credible Layer represents a transformative leap in securing decentralized systems, ensuring that innovation, adoption, and user trust are interdependent. This shift is not just necessary—it’s the cornerstone of blockchain’s future.
Conclusion:
Web3 security is more than a technical challenge—it's the defining competitive advantage for blockchain platforms. Layer 2 solutions that successfully implement robust security measures will become market leaders, thereby transforming security into a competitive race.
For users, enhanced security isn't just about protecting assets—it's about trust. Cryptographic proofs transform the user experience from blind faith to verifiable confidence, making it as secure as traditional banking.
The security innovation flywheel is powerful:
Better security = more capital = more funds for dApps = more users = mass adoption.
Unlike speed or UX, security is the foundational requirement for mainstream crypto adoption. Investors, developers, and users will gravitate toward platforms that can demonstrably protect their digital assets.

Really interesting article looking at how web3 security can indeed be a defining USP for on-chain projects. Especially interesting to see projects using decentralized security models/ training models incentivising the best of the community to solve problems. We are doing something similar by incentivising users to attempt to bypass bot detection frameworks at https://www.theredteam.io/ on Bittensor. If more solutions can do this in the web3 space, it turns the traditionally expense heavy, laborious R&D process into a much more powerful arm of both the business and the industry as a whole.
