Crypto Hackers Just Stole a Small Fortune

by

Ah, the joys of cryptocurrency! Where the promise of easy wealth and financial freedom is always just a hack away. 🤑 Singapore-based crypto exchange BigONE just learned this lesson the hard way, as hackers made off with a cool $27 million in assets. 💸

But don’t worry, folks! The security teams are on it, racing to track down the stolen funds like a bunch of digital detectives. 🔍

So, what happened? Well, it’s quite simple really. The hackers launched a stealthy supply chain attack, compromising key servers and allowing them to withdraw crypto assets without ever needing those pesky private keys. 🔑

The Hack: A Step-by-Step Guide

According to BigONE’s official statement, the attack targeted their production network, which is just a fancy way of saying “the important stuff.” The hackers modified the operating logic of account and risk control related servers, enabling them to withdraw funds at will. 💸

Blockchain security firm SlowMist, which is now on the case, confirmed that the breach was indeed a supply chain attack – one of the most sophisticated and stealthy forms of cyber intrusion in the crypto space. 🕵️‍♂️

And the best part? The hackers didn’t even need to steal private keys! They just found a weakness in the system and exploited it, like a digital version of finding a spare key under the doormat. 🔑

Suspicious Wallet Movements Detected

Blockchain security firm CertiK Alert was the first to notice strange activity from wallet address 0xd4d…d93f. This wallet was used to move out stolen tokens linked to the BigONE exchange hack. 🚨

Later, the stolen assets were sent to another wallet, 0x0a3…05f4f, which now holds around $4 million in Ethereum (ETH) and many other tokens. It’s like a digital game of hide-and-seek, except with millions of dollars on the line! 🎉

The hacker didn’t just take ETH, though. Oh no, they also made off with SHIBA INU, CelerToken, and several small altcoins. It’s like they were trying to collect them all! 🎊

Quick Action and Compensation Plan

BigONE’s team moved fast to contain the situation, like a team of digital firefighters putting out a blaze. 🔥 They’ve promised to cover any losses faced by users, which is nice of them. 🙏

The attack path has been blocked, and further losses have been prevented. The platform reassured users that their private keys remain safe and intact, which is a relief. 🙌

They’re also doing a full review to improve their system’s safety before turning everything back on. It’s like they’re saying, “Okay, let’s take a deep breath and try this again.” 👍

Should I Withdraw from BigONE?

Following the recent security breach, BigONE has temporarily paused deposits, withdrawals, and trading services. It’s like they’re saying, “Hold on, folks, we need to get our house in order.” 🚧

For now, users can’t withdraw funds, but BigONE has promised that all user losses will be fully covered and that funds remain safe. It’s like they’re saying, “Don’t worry, we’ve got this.” 😊

What happened in the BigONE exchange hack?

In July 2025, Singapore-based crypto exchange BigONE was targeted in a sophisticated supply chain attack. Hackers breached its production network, compromising key servers without needing access to private keys. Over $27 million in assets were drained from hot wallets before the attack was contained.

Was BigONE exchange hacked in July 2025?

Yes, BigONE suffered a major security breach in July 2025 due to a stealthy supply chain attack. Blockchain firms like SlowMist and CertiK are now helping track the stolen funds, which include Ethereum, SHIBA INU, CelerToken, and more.

 How did hackers bypass private keys in the BigONE hack?

The attackers didn’t need to steal private keys. Instead, they exploited vulnerabilities in BigONE’s production network using a supply chain attack. This allowed them to access internal systems and authorize withdrawals directly from the hot wallet.

What is a supply chain attack in crypto?

A supply chain attack in crypto occurs when hackers infiltrate trusted software, infrastructure, or third-party services used by a platform. Instead of attacking the platform directly, they manipulate dependencies to gain unauthorized access, making it one of the most difficult types of hacks to detect and stop.
