Maya Protocol Halted After $1.4M Bitcoin Theft Exploiting Six Bugs

Cross-chain protocol Maya Protocol suspended operations after attackers exploited six software vulnerabilities to steal approximately $1.7 million in Bitcoin and other assets. By forging liquidity pool balances, the attackers took control of pools and drained large amounts of CACAO tokens, causing CACAO's price to plummet nearly 89%. The team has released a post-mortem report and published the attacker's address, hoping to recover funds as a bug bounty. The incident exposed shortcomings in the protocol's code auditing, and the team stated it will adopt a more adversarial review approach.

Binance Thwarts $1.2M DAO Governance Attack

On August 18, Binance announced that its security team successfully thwarted a malicious governance proposal targeting an unnamed decentralized autonomous organization (DAO), which could have stolen approximately $1.2 million in treasury tokens. Binance detected the threat less than 48 hours before the proposal's execution and immediately contacted the project team, while also coordinating with other centralized exchanges to suspend deposits of the affected token. The project team voted against the proposal before execution, and Binance stated that no funds were lost. Binance did not disclose the project's name, proposal ID, or on-chain transaction records, but noted that the attacker exploited a vulnerability in the project's governance mechanism where the threshold for creating proposals was too low.

Crypto Breaches 2026: Shipping Leaks Fuel Physical Attacks

In August 2026, SafePal, Trezor, and Bits of Gold disclosed data breaches within four days, exposing the names, phone numbers, addresses, and purchase histories of approximately 253,000 customers. The Trezor and Bits of Gold breaches stemmed from the same vulnerability, CVE-2026-72898, a critical SQL injection flaw in Metabase. This data was used to target cryptocurrency holders in physical attacks (wrench attacks), which surged 33% in the first half of 2026, causing $124.1 million in financial losses. The article analyzes the common technical root cause and highlights the structural inadequacies of hardware wallet manufacturers and brokers in addressing such threats.
