~$10.26M Lost: Term Finance, MAYAChain | BlockSec Weekly

During the week of August 17-23, 2026, two notable security incidents resulted in approximately $10.26M in total losses across Ethereum and MAYAChain. The highlighted Term Finance incident (~$8.5M) was a flawed governance design rather than a coding bug: each vault ships its own on-chain DAO whose support-threshold and participation checks are purely relative, with no absolute floor; with almost no one taking part in governance, there was no electorate to vote a proposal down and no guardian to cancel one, so an attacker acquired a supermajority of a vault's voting power for roughly 0.5 ETH and, after the execution delay elapsed, drained six of Term's vaults for approximately $8.5M in total. MAYAChain (~$1.76M) lost funds to a chain of accounting and state-validation defects, where a single crafted deposit made valid withdrawals appear to have failed, triggered a recovery path that inflated a low-liquidity pool's recorded native-token balance with no real backing, and let the attacker drain the inflated value by adding and withdrawing liquidity.

Harmony Cross-Shard ONE Mint + ~$47M Key Losses | BlockSec Weekly

During the week of August 10-16, 2026, 5 notable security incidents are featured, involving approximately $47M in quantified losses, with the detailed analysis focused on a chain-implementation flaw in the Harmony Layer-1. Harmony suffered unauthorized minting of native ONE through a cross-shard receipt replay: destination shards derived the receipt spent-marker from unauthenticated MerkleProof.ShardID and BlockNum fields instead of the signed source header, so an already-credited receipt could be replayed with no matching source-shard debit. Approximately 3.01T ONE was forged, but its nominal value far exceeds the token's market capitalization and is neither realizable nor confirmed realized loss, so Harmony is excluded from the total; the ~$47M came from private-key compromises (Unknown Whale Wallet ~$25M, Kite ~$14M, and Coinsbuy ~$7.9M) plus a Fox business-logic flaw (~$117K).

~$1.6M Lost: Moke Token, LpdFi Exploits | BlockSec Weekly

During the week of August 3-9, 2026, 2 notable security incidents on BNB Chain resulted in approximately $1.6M in total losses, both from price manipulation. The highlighted LpdFi incident (~$697K) reused the same manipulable PancakeSwap pair reserves for both order valuation and interest redemption, letting the attacker inflate a position's principal and reshape the pool to redeem an oversized interest claim. Moke Token (~$906K) combined a manipulable spot price with duplicated LP dividend accounting to claim inflated MOKE and collect the resulting BNB dividends multiple times.
