Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
October 2026 marked one of the worst months for crypto cybersecurity, with a record hack of Binance, an attack on Polymarket, compromised Ledger and Trezor wallets, and critical vulnerabilities discovered in PHP and Linux. Despite the string of incidents, Bitcoin showed relative resilience, ending the month down 7.3%. The Binance breach stands out as a record-setting event for the exchange, while the Polymarket attack and hardware wallet compromises raised concerns about security across both centralized and decentralized platforms. The PHP and Linux flaws highlighted systemic risks beyond crypto-native infrastructure. Market participants will be watching whether exchanges and wallet providers disclose post-incident remediation details and whether Bitcoin's relative stability holds amid ongoing security fallout.
