Opening
Are you worried that the crypto platform you use could be vulnerable to a hack? This article explains how exchange hacks work, why they happen, and what steps you can take to keep your assets safer.
The plain explanation
A crypto exchange is a service that lets users buy, sell, and store digital assets. To move funds, an exchange uses two types of wallets:
- Hot wallets – online wallets that are connected to the internet. They enable fast withdrawals but are exposed to external attacks.
- Cold wallets – offline storage devices that keep the bulk of assets away from the internet, making them much harder to steal.
Hackers target the weak points in an exchange’s infrastructure. The most common attack vectors are:
- Compromised credentials: If attackers obtain login details or internal API keys, they can issue withdrawal commands just like a legitimate employee.
- Vulnerabilities in third‑party software: Exchanges often rely on external security products, monitoring tools, or cloud services. A flaw in any of these can give attackers a backdoor.
- Insider threats: Employees with privileged access might misuse their rights, either maliciously or by being coerced.
- Social engineering: Phishing emails or phone calls trick staff into revealing passwords or approving transactions.
Once inside, attackers typically focus on “hot wallets” because those contain the liquid funds needed for immediate withdrawals. They may forge withdrawal commands, create new addresses, or manipulate the exchange’s internal accounting to move assets to their own wallets.
To limit damage, reputable exchanges employ multiple safeguards:
- Multi‑signature (multisig) controls that require several independent approvals for large withdrawals.
- Real‑time monitoring and anomaly detection to flag unusual transaction patterns.
- Segregation of duties, ensuring no single employee can move large sums alone.
- Regular security audits of both internal code and any third‑party components.
Even with these measures, the combination of high-value targets and constantly evolving attack techniques means no platform is immune.
A real example
In September 2026, the exchange Bitget suffered a major breach. Attackers exploited a vulnerability in a third‑party security product, obtained internal credentials, and forged withdrawal commands from the exchange’s hot wallets. The hack resulted in roughly $387.5 million being stolen, accounting for about 31 % of all crypto‑security losses in the third quarter of 2026, according to the blockchain security firm CertiK.
Bitget detected the unauthorized transfers on September 24 and immediately suspended withdrawals. The incident highlighted how a single third‑party flaw can cascade into a massive loss, even for a platform that otherwise follows industry best practices.
What it means for you
If you keep your crypto on an exchange, you are effectively trusting the platform’s security controls. A successful hack can result in the loss of your deposited assets, often with little recourse. While some exchanges maintain insurance funds or compensation schemes, the amount recovered may be far less than the original loss, and the process can take months.
For users who aim to earn passive income through staking, lending, or cloud mining, the risk is amplified because those services usually require funds to stay on the platform for extended periods. A breach can freeze or permanently remove the capital you intended to grow.
What to check / how to judge
Before depositing a significant amount, evaluate the exchange on the following criteria:
- Security audits: Look for publicly available third‑party audit reports. Reputable firms such as CertiK, Trail of Bits, or Quantstamp often publish findings.
- Hot‑wallet limits: Platforms that keep only a small percentage of total assets in hot wallets reduce exposure. Check if the exchange discloses this ratio.
- Multisig and withdrawal approvals: Confirm that large withdrawals require multiple signatures or manual review.
- Insurance or compensation fund: Some exchanges maintain a reserve to reimburse users after a breach. Understand the terms and coverage limits.
- History of incidents: Review past security incidents and how the exchange responded. Prompt suspension of withdrawals and transparent communication are good signs.
- Third‑party dependencies: If the exchange relies heavily on external security products, investigate whether those vendors have a solid security track record.
FAQ
Is it safer to keep my crypto on a hardware wallet than on an exchange?
Yes. A hardware (cold) wallet stores your private keys offline, making it immune to online hacks. However, you must manage the device securely and back up the recovery phrase.
Can I recover funds if an exchange gets hacked?
Recovery depends on the exchange’s insurance, legal actions, and cooperation with law enforcement. In many cases, only a portion of the stolen assets is returned, and the process can be lengthy.
Do “proof‑of‑reserve” audits guarantee my funds are safe?
Proof‑of‑reserve audits show that an exchange holds enough assets to cover user balances at a specific moment, but they do not prevent future hacks or operational failures.
Should I spread my assets across multiple exchanges?
Diversifying reduces the impact of a single breach. Keeping only a small amount on any one platform limits potential loss while still allowing you to earn rewards where you choose.
