August 4, 2025 – Crypto World Rocked by Supply Chain Attack on BigONE Exchange

In one of the most alarming and sophisticated heists of 2025, Seychelles-based BigONE crypto exchange has confirmed that $27 million was drained from its hot wallets — without a single private key being exposed.

How? A crypto supply chain attack from the inside.

> Hackers didn’t steal keys. They rewrote reality inside the exchange.

BigONE revealed that attackers infiltrated its internal infrastructure, deploying malicious code to manipulate accounting and risk systems, giving them temporary access to withdraw funds. It was surgical. Silent. Devastating.

What Was Stolen?

121 $BTC (~$13.7 million)

350 $ETH (~$1.25 million)

9.69B $SHIB

538,000 DOGE, and more

Tether (USDT) and USD Coin (USDC) in significant quantities

Total losses: $27,000,000 — gone in minutes.

This supply chain breach wasn’t detected until millions had already vanished, and it took investigators hours to understand the full scope.

The Mastermind Move: No Keys, No Code Exploits

Instead of going after wallets directly, attackers compromised a BigONE developer through social engineering. This gave them privileged backend access — bypassing traditional defenses like key vaults, firewalls, and smart contract audits.

With access granted, they rewired the system’s logic — making unauthorized withdrawals appear legitimate.

> “It was like hijacking the brain of the exchange itself,” one investigator said.

Aftermath: Insurance Tapped, Bounty Set

BigONE activated its emergency insurance reserve to cover user losses.

A $8 million bounty has been posted for info leading to the attackers.

SlowMist, a top blockchain forensics firm, is now tracing the funds — already scattered across Ethereum, BNB, Tron, and Solana.

Bigger Problem: The Industry’s Security Illusion?

This attack isn’t isolated. 2025 is shaping up as the most dangerous year for crypto security:

CoinDCX: $44M hacked

GMX: $40M exploit

Arcadia Finance: $3.5M drained

Coinbase: Internal data breach

> Crypto is no longer just vulnerable at the edges. The danger now lives within.

Final Word:

If BigONE — a major CEX with layered security and insurance — can be breached without a single key leak, no one is safe from what blockchain experts now call "supply chain warfare."

As systems become more automated and centralized exchanges lean heavily on continuous integration tools, one compromised developer or internal system can be the gateway to disaster.

Crypto traders, brace yourselves. This isn’t just another hack. It’s a wake-up call.

Stay alert. Stay decentralized. #ScamAwareness
