Phemex Investigates $29M Loss in Hot Wallet Hack Reports

Singapore-based cryptocurrency exchange Phemex is investigating the breach after reports of multiple suspicious transactions.

While the company’s CEO, Federico Variola, has assured users that cold wallets remain secure, the incident raises critical questions about crypto wallet security.

Phemex Investigates Hack Affecting Hot Wallets

On January 21, 2025, crypto security firm Cyvers reported multiple suspicious transactions originating from one of Phemex’s hot wallets. The stolen funds, reportedly valued at $29 million, were swiftly swapped for Ether (ETH) across multiple blockchains. This alarming discovery sparked immediate concern among traders and stakeholders.

Federico Variola, CEO of Phemex, addressed the issue via X (formerly Twitter), stating, As we look into a report on one of our hot wallets, rest assured our cold wallets remain safe and can be checked by everyone here. We will post more updates shortly.

While the company investigates the Phemex hot wallet hack, users are left wondering how such a significant breach occurred in a platform known for its security-first approach.

Hot wallets are digital wallets connected to the internet, enabling seamless crypto transactions. While convenient, they are more vulnerable to cyberattacks compared to cold wallets, which remain offline. The Phemex hot wallet hack highlights the inherent risks of internet-connected storage, particularly for exchanges managing high-value assets.

Blockchain analyst Jason Tan from Cyvers explained, Hot wallets are essential for liquidity but often become targets for sophisticated hackers due to their online accessibility. Regular security audits and advanced encryption protocols are crucial for minimizing these risks.

Cyvers forensic investigation into the Phemex hot wallet hack suggests that the hackers executed a highly coordinated attack. They identified vulnerabilities in the wallet’s infrastructure, exploiting them to transfer assets without triggering security alerts.

Reports indicate that the stolen funds were transferred in multiple transactions to obscure their origin before being converted to ETH. This multi-step strategy complicates recovery efforts, making it challenging for authorities to trace and retrieve the funds.

Maya Lin, a cybersecurity expert at BlockSec, weighed in on the situation, stating, The hackers likely employed advanced tactics, including blockchain obfuscation tools, to mask their tracks. This level of sophistication points to organized cybercrime groups rather than lone actors.

In the wake of the Phemex hot wallet hack, the exchange has taken immediate steps to reassure its users. Federico Variola emphasized the security of Phemex’s cold wallets, which store the majority of user funds offline.

We are actively working with blockchain analytics firms and cybersecurity experts to trace the stolen assets and strengthen our defenses, Variola wrote on X.

Phemex has also temporarily disabled deposits and withdrawals to prevent further breaches while investigations continue. This decision, although inconvenient for users, underscores the exchange’s commitment to safeguarding assets.

The Phemex hot wallet hack is the latest in a string of cyberattacks targeting crypto exchanges. In 2024 alone, the industry lost over $3.7 billion to hacks, according to a report by Chainalysis. These incidents erode user trust and highlight the urgent need for enhanced security protocols across the board.

Paul Kruger, an industry analyst, noted, Exchanges must prioritize security over convenience. While hot wallets facilitate faster transactions, they should only store minimal funds. The bulk of assets should remain in cold storage, with robust multi-factor authentication protecting access.

As the investigation into the Phemex hot wallet hack unfolds, the exchange faces mounting pressure to recover the stolen assets and rebuild user trust. The platform’s ability to handle this crisis could set a precedent for how the industry addresses similar incidents in the future.

Regulatory bodies may also increase scrutiny on crypto exchanges, demanding stricter compliance with security standards. This could lead to widespread reforms, forcing platforms to adopt more robust risk management strategies.

Despite the setback, Federico Variola remains optimistic about Phemex’s resilience. We are committed to learning from this incident and emerging stronger. User security remains our top priority, he affirmed.

For users, this is a call to action to take proactive steps in securing their assets. Diversifying storage methods, enabling security features, and staying informed can mitigate the impact of such incidents.
