Binance hack exposes security gaps across five blockchain networks 

A massive $6.36 billion security incident at Binance has exposed wallets across ten different blockchain networks, placing five major ecosystems under intense scrutiny.

Investigators have linked the sophisticated attack to North Korea's TraderTraitor group, which targeted billions of dollars in assets across Bitcoin, Ethereum, XRP, TRON, and Solana.

While investigators emphasize that no protocol-level breaches occurred within the networks themselves, the exploitation of specific features, such as Ethereum's EIP-7702 delegation, allowed the attackers to siphon massive sums, including 18,270 BTC and 200,630 ETH.

The aftermath of the breach has starkly highlighted the structural divide in crypto regulation and control; while central authorities successfully froze roughly $2.7 billion in issuer-controlled tokens, truly decentralized assets remained entirely immune to external intervention.

Here are five of the blockchain networks connected to the Binance incident.

Bitcoin (CRYPTO:BTC)

Bitcoin recorded approximately 18,270 BTC in outflows from Binance wallets, valued at roughly US$1.47 billion when transferred.

The attacker divided the Bitcoin into 19 wallets, including 17 holding exactly 1,000 BTC each.

As of October 30, Bitcoin's tracked DeFi total value locked (TVL) stood at US$5.95 billion, with 633,944 transactions recorded over 24 hours.

Its 24-hour decentralised exchange (DEX) volume reached approximately US$1.09 million, reflecting a smaller decentralised trading market than Ethereum or Solana.

Bitcoin's lack of a central token issuer also means no authority can directly freeze BTC through an issuer-controlled blacklist.

Ethereum (CRYPTO:ETH)

Ethereum recorded approximately US$3.79 billion in Binance-related outflows, including 200,630 ETH and numerous other tokens.

The attacker exploited Ethereum's EIP-7702 delegation feature, using 50 pre-signed authorisations to execute unauthorised wallet transactions.

Ethereum's tracked DeFi TVL reached US$44.53 billion on October 30, while its 24-hour DEX volume reached US$3.75 billion.

The network also recorded approximately US$764,657 in chain fees over 24 hours, reflecting activity across its underlying infrastructure.

Ethereum's role in stablecoin settlement and decentralised finance makes its transaction infrastructure relevant to the investigation's recovery efforts.

XRP (CRYPTO:XRP)

The XRP Ledger recorded outflows of approximately 233.46 million XRP, valued at US$296 million when transferred from Binance wallets.

The transactions occurred between 20:05 and 20:09 UTC on October 29, with five Binance wallets sending funds to an attacker-controlled address.

The XRP Ledger's tracked DeFi TVL reached approximately US$333.87 million, while its 24-hour DEX volume stood at US$4.43 million.

The network recorded 228,906 transactions on October 30, including 182,174 successful transactions, according to XRPScan.

The incident highlights the XRP Ledger's role in cross-border digital asset transfers, while the investigation centres on Binance wallet authorisations.

TRON (CRYPTO:TRX)

TRON recorded approximately US$628 million in Binance-related outflows, including 612.7 million USDT and 46.4 million TRX.

The transfers occurred within the same attack window as the Ethereum, Bitcoin and XRP Ledger movements.

TRON's tracked DeFi TVL reached US$5.64 billion on October 30, while its 24-hour DEX volume reached approximately US$97.27 million.

Its stablecoin market capitalisation stood at approximately US$94.15 billion, with USDT accounting for 97.87% of that total.

TRON's large stablecoin presence makes it an important settlement network in the movement of digital dollars.

Solana (CRYPTO:SOL)

Solana recorded approximately 970,500 SOL in Binance-related outflows, valued at around US$96 million when transferred.

The transfers formed part of the initial wave of unauthorised movements across Binance's connected blockchain wallets.

Solana's tracked DeFi TVL reached approximately US$5.46 billion on October 30, with 24-hour DEX volume reaching US$1.71 billion.

The network also recorded approximately US$527,147 in chain fees and US$3.59 million in application revenue over 24 hours.

Solana's high on-chain trading activity places it among the major ecosystems affected by the wider Binance incident.

The bottom line

The Binance security incident exposed different recovery challenges across five major blockchain ecosystems, with approximately US$2.7 billion frozen through issuer and network interventions.

Bitcoin presents a different recovery challenge because no central issuer can freeze its native tokens, while stablecoin issuers can restrict transfers through their token contracts.

The incident also reinforces the importance of exchange wallet authorisation, cross-chain security controls and independent blockchain monitoring.
