November 1, 2024

Security at a Glance πŸ‘€

Radiant: $58M

On October 16th, Radiant Capital suffered a security breach on Arbitrum and BSC, resulting in losses exceeding $50M. While the complete technical details of the exploit remain undisclosed, the protocol team confirmed the compromise of several developer wallets as the attack vector.

Unknown: $1.4M

On October 24th, an unknown Compound-fork protocol was exploited on Base, resulting in a loss of approximately $1.4m. While the affected contracts were unverified at the time of the incident, our analysis indicates that this attack was probably due to vulnerable price dependency on Uniswap spot price.

EGA: $554K

On October 5th, an unverified contract was exploited on BSC, causing a loss of $554k. The root cause was the lack of slippage protection in the function that buys EGA tokens from Pancake pairs, susceptible to price manipulation attacks.

P719: $315K

On October 11th, P719 token was exploited on BSC, resulting in a loss of $315k. While the compromised contract was unverified, we suspect the root cause was a flawed token burn mechanism within the P719 trading functionality.

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.
