NIGHT coin daalde 30% door Wanchain"},"content":{"rendered":"

Hackers stalen 515 miljoen NIGHT-tokens – circa $9 miljoen – via een kwetsbaarheid in de Wanchain Cardano-BNB cross-chain bridge<\/a>, en zeven grote exchanges bevroren op verzoek van de Midnight Foundation onmiddellijk de wallets van de aanvaller. De NIGHT-koers daalde tijdelijk met meer dan 30% naar een all-time low van $0,016. Zijn de gestolen fondsen nog te redden, of heeft de aanvaller het merendeel al buiten bereik gebracht?<\/p>

Hoe de aanvaller de bridge leeghaalde in minuten<\/h2><\/span>

De kwetsbaarheid zat in de TreasuryCheck-validator van de Wanchain-brug, die ongeveer twee jaar operationeel was. Beveiligingsanalisten van BlockSec’s Phalcon-platform<\/a> stelden vast dat het contract 14 datavelden aaneengesloten verwerkte zonder scheidingstekens.<\/p>

De aanvaller hergebruikte een legitieme BNB Chain-handtekening die bedoeld was voor een overdracht van slechts 3.110 NIGHT. Door het ontbreken van duidelijke grenzen tussen de datavelden kon diezelfde handtekening aan de Cardano-kant worden ingezet om de transactie met een factor 65.000 op te blazen – van 3.110 naar 203 miljoen NIGHT in \u00e9\u00e9n operatie. Dit type aanval houdt in dat een legitieme BNB Chain-handtekening opnieuw wordt gebruikt door het ontbreken van duidelijke grenzen tussen de datavelden, waardoor de transactie met 65.000 keer wordt opgeblazen.<\/p>

De Wanchain-brug is inmiddels volledig uitgeschakeld terwijl het team de kwetsbaarheid in de architectuur patcht. Een direct structureel gevolg is dat wrapped NIGHT-tokens op BNB Chain tijdelijk zonder onderpand kwamen te staan, doordat de Cardano treasury werd leeggehaald.<\/p>

Zeven exchanges bevriezen gestolen fondsen<\/h2><\/span>

De Midnight Foundation – de organisatie achter het privacy-gerichte Cardano-sidechain Midnight – activeerde direct een geco\u00f6rdineerde respons. Binance, OKX, Kraken, KuCoin, Bybit, Gate en MEXC blacklistten de wallets van de aanvaller, tijdelijk geassocieerde accounts bevroren en staakten NIGHT-deposits en -withdrawals. Daarmee werd de liquidatie van 515 miljoen NIGHT-tokens geblokkeerd.<\/p>

De aanvaller slaagde er desondanks in circa 290 miljoen tokens te dumpen via Cardano DEX’en, waar geautomatiseerde bevriezingen technisch niet mogelijk zijn. Die verkopen veroorzaakten de scherpe koersdaling naar $0,016.<\/p>

Cardano en Midnight blijven operationeel<\/h2><\/span>

De Midnight Foundation benadrukte in haar offici\u00eble update dat zowel het Midnight Layer 1-netwerk als de Cardano-blockchain<\/a> normaal blijven functioneren. De kwetsbaarheid was volledig ge\u00efsoleerd binnen de Wanchain bridge-code en is geen systeemfout in de kernprotocollen van beide netwerken. De Foundation waarschuwde de community bovendien uitsluitend offici\u00eble communicatiekanalen te volgen vanwege verhoogd phishing-risico in de nasleep van het incident. De kwetsbaarheid was volledig ge\u00efsoleerd binnen de Wanchain bridge-code.<\/p>

Vooruitblik: herstelplan en audit staan centraal<\/h2><\/span>

De Midnight Foundation benadrukt dat de incidentrespons gericht is op het isoleren van de gestolen fondsen binnen gecentraliseerde systemen. De Midnight Foundation zet het onderzoek voort en is de onderzoek voortzetting; er is in de update geen formeel herstelplan genoemd; <\/p>

Voor beleggers die bredere Cardano-ontwikkelingen volgen biedt de Cardano-Volvo samenwerking<\/a> context over hoe het ecosysteem zich los van dit incident blijft ontwikkelen. Cruciale signalen om te bewaken: de Wanchain-brug is volledig uitgeschakeld terwijl het team de kwetsbaarheid in de architectuur patcht de communicatie van de Midnight Foundation over het onderpandprobleem op BNB Chain, .<\/p>","protected":false},"excerpt":{"rendered":"
