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.
