What are the major security risks and hacks in Solana's history and how do they impact SOL investors?

Major Security Breaches: From $58 Million in Stolen Assets to Multi-Million Dollar Exchange Hacks

The cryptocurrency exchange landscape in 2025 has been marked by unprecedented security vulnerabilities, with major platforms suffering substantial losses. These incidents have exposed critical weaknesses in infrastructure and operational security across the industry.

Two of the most significant breaches occurred within months of each other. The MEXC platform reported a $58 million theft involving Solana-based assets, while South Korea's Upbit experienced a $36 million hack also targeting Solana network deposits. Beyond direct exchange compromises, approximately $33 million in additional losses resulted from wallet compromises caused by stolen credentials and malware attacks.

July 2025 proved particularly devastating, with four major platforms falling victim to coordinated attacks resulting in approximately $139 million in combined losses. The first half of 2025 alone exceeded $3.1 billion in total crypto sector losses, surpassing the entire previous year's figures. This surge stemmed primarily from access control flaws, phishing schemes, and rapidly evolving AI-driven exploits that increased by over 1,000 percent compared to 2024.

These breaches reveal systemic vulnerabilities in exchange security protocols and the pressing need for enhanced infrastructure safeguards. The pattern demonstrates that security gaps continue widening despite increasing awareness of threats.

Smart Contract and Supply Chain Vulnerabilities: The @solana/web3.js Attack and Wallet Exploits

Solana's ecosystem faced a significant security crisis when the @solana/web3.js library, one of the most widely used JavaScript SDKs in the network, fell victim to supply chain attacks. Attackers compromised maintainer accounts through phishing and injected malicious code into versions 1.95.6 and 1.95.7, distributing backdoors to thousands of applications. This vulnerability exposed a critical weakness in development infrastructure where a single compromised dependency could impact the entire ecosystem.

The attack exploited multiple attack vectors simultaneously. On the smart contract level, common vulnerabilities including reentrancy, integer overflow/underflow conditions, improper validation of program-derived addresses, and missing signer checks created pathways for exploitation. Cross-program invocation (CPI) mechanisms introduced additional risks when developers failed to properly validate inputs and outputs across contract boundaries.

Wallet exploits compounded these technical vulnerabilities through sophisticated phishing attacks targeting Solana users via Phantom wallet extensions on Windows systems. Attackers employed transaction spoofing techniques, silently appending drainer instructions to legitimate transactions. The consequences proved severe, with incidents like the Wormhole Bridge hack demonstrating how compromised private keys could result in losses exceeding millions of dollars.

The @solana/web3.js incident, designated CVE-2024-54134, underscored that security threats extend beyond code logic to encompass the entire development supply chain. Solana's response included revoking compromised versions from npm and releasing patched version 1.95.8, yet the incident highlighted fundamental architectural vulnerabilities requiring rigorous audits, automated security tools like solsec, and continuous validation practices across all development stages.

Centralized Exchange Risks: Upbit's $44.5 Million SOL Theft and Custody Dangers for Investors

Upbit's November 2025 theft of 36.9 million dollars in Solana assets represents a critical reminder of centralized exchange custody risks. This incident, occurring exactly six years after a 50 million dollar Ethereum heist on the same date, reveals systemic vulnerabilities in exchange security infrastructure. The 2025 breach exploited weaknesses in Upbit's digital signature systems and compromised hot wallet operations, enabling attackers suspected to be North Korean-affiliated groups to drain substantial Solana ecosystem tokens including SOL, USDC, BONK, JUP, and RENDER.

The event demonstrates that centralized exchanges remain susceptible to sophisticated attacks despite previous incidents. Exchange custody introduces counterparty risk where investors depend entirely on platform security protocols. Upbit's swift response—halting all withdrawals, freezing approximately 12 billion won in stolen assets, and pledging full user compensation—provided temporary relief. However, the breach underscores the importance of custody alternatives. Investors face a critical choice between exchange convenience offering staking benefits and insurance, versus self-custody through hardware wallets that eliminates platform risk entirely. Understanding these tradeoffs remains essential for SOL investors evaluating where to store their assets in an increasingly volatile security landscape.

FAQ

What is a sol coin?

SOL is the native cryptocurrency of the Solana blockchain, used for transaction fees, staking, and network participation. It powers a high-speed platform capable of processing thousands of transactions per second, enabling decentralized applications and DeFi services.

Is Sol Coin a good investment?

Sol Coin offers strong potential with robust network fundamentals, growing developer ecosystem, and increasing transaction volume. Its scalability and cost efficiency make it attractive for long-term investors seeking exposure to high-performance blockchain technology.

Can Sol reach $1000 USD?

Yes, Solana has potential to reach $1000 USD. With growing institutional adoption, upcoming spot ETFs, expanding stablecoin and DePIN sectors, and strong ecosystem development, SOL's trajectory suggests significant long-term growth potential.

What will Sol be worth in 5 years?

In 5 years, Solana (SOL) is projected to reach around $1,200. This forecast is based on expanding DeFi adoption, strong developer ecosystem growth, and potential institutional inflows driving sustained network value appreciation.
