The $AIRWA token on Binance Smart Chain was exploited due to a critical vulnerability in its smart contract. Launched just a day earlier, the contract lacked access control on its setBurnRate() function, allowing anyone to change the token’s burn rate. The attacker exploited this flaw to manipulate the tokenomics and trade ~12 AIRWA for ~57 BNB (worth approximately $33.6K). The project has not issued any public response, and there is no indication of recovery efforts. The stolen funds appear to be permanently lost.[1][2][3][4][5][6][7][8][9][10][11]
About AIRWA Token
The AIRWA smart contract/token was created in the morning of April 3rd, 2025.
The Reality
Unfortunately, the contract was launched with a lack of access control on the setBurnRate function, allowing funds to be drained.
What Happened
The $AIRWA token was exploited due to a missing access control on the setBurnRate() function, allowing an attacker to manipulate tokenomics and steal approximately $33.6K in BNB.

Technical Details
The exploit of the $AIRWA token on the Binance Smart Chain (BSC) on April 4th stemmed from a critical access control vulnerability in the token's smart contract. Specifically, the contract exposed a public setBurnRate() function, which allowed any user to arbitrarily modify the burn rate of the token — a parameter that controls how much of the token is destroyed or removed from circulation during transfers or conversions.
The attacker exploited this flaw by calling setBurnRate() and setting the burn rate to a maliciously high or strategic value. This manipulation altered the internal tokenomics, allowing the attacker to trade a very small amount of $AIRWA (about 12 AIRWA tokens) and extract a disproportionately large amount of BNB — roughly 57 BNB, worth around $34,000 at the time. Because this function should have been restricted to the contract owner or admin, the lack of proper access control was the root cause of the vulnerability.
The attack involved three key addresses:
Attacker’s wallet: 0x70f0406e0A50C53304194B2668Ec853D664a3D9C
Attack contract: 0x2a011580f1b1533006967bd6dc63af7ae5c82363
Targeted AIRWA contract (non-open source): 0x3af7da38c9f68df9549ce1980eef4ac6b635223a
