Slow Mist Cosine Identifies Suspicious Parameter Manipulation in BNB Chain LABUBU Liquidity Pool Exploit
2026-06-20 22:01

Data compiled by Woofun AI shows that Slow Mist founder Cosine has published an analysis regarding a suspicious incident involving the OLPC and LABUBU liquidity pool on BNB Chain, which resulted in approximately $1.1 million in losses. The investigation highlights a severe imbalance in the trading pair triggered by a vulnerability in the OLPC token contract.

the root cause stems from an abnormal modification of the decimalsValue parameter. Approximately 46 days before the attack, the OLPC owner altered this value from the standard 1 to an exceptionally large figure of 7,326,680,472,586,200,649. Shortly thereafter, ownership was renounced by setting the address to zero. An attacker subsequently exploited this inflated decimalsValue to trigger a reserve burn in the Pair contract, enabling the extraction of significant LABUBU tokens using a minimal amount of OLPC. The attacker ultimately swapped 1.115 million USDT at a low cost, raising questions about the intent behind the initial parameter adjustment.
