BANKROLL NETWORK

DESCRIPTION OF EVENTS

"Bankroll is the best way to HODL and grow your crypto!"

 

"Bankroll is a premiere decentralized finance network on TRON. It implements a voluntary, sustainable, and permissionless global economic engine. Through a network of financial contracts the platform provides rewards in TRX, BNKRX, and BNKR. Bankroll... play to win!!!"

 

"Bankroll is a premiere decentralized finance network on the TRON blockchain. It implements a voluntary, sustainable, and permissionless economic global engine. Through a network of financial contracts the platform provides rewards in TRX, BNKR, BNKRX, and BTT. Bankroll… play and win!!! Bankroll simply put is a decentralized community bank. As a financial mutual organization; Bankroll holds a native store of value tied to TRON. These tokens are BNKR and BNKRX. BNKR is our digital cash and is more liquid than VLT on the Ethereum side of the network. BNKRX is our elastic reward token, which scales to the savings rate of the community. Both tokens are supported by several contracts which mine, exchange, and store value on the network."

 

"Victim contract is a token sale contract, there’re functions for buying and selling tokens. To buy tokens, users need to send WBNB to the pool, and some of that WBNB is used as fee(like reward to Liquid Providers).

 

This means “profitPerShare_” is increased when user buys tokens. Root cause of this hacking is in “buyFor” function. It’s a function for buying tokens on behalf of other user.

 

If “_customerAddress” is the same as address of victim contract, anyone can increase “profitPerShare_” without WBNB tokens.

 

Hacker bought some tokens before attack, and called “buyFor” function hundreds of times. “profitPerShare_” became much bigger than before, he could gain much more WBNB tokens by calling “withdraw” function.

 

He gained $230k."

 

"ALERT Our system has detected a suspicious transaction involving @Bankroll_Status on #BNB with loss of #230k It seems that #dualpools hacker is behind the suspicious transaction!. Our system has detected malicious contract deployment targeting #Bankroll 90 days ago!"

On September 22nd, 2024, a vulnerability in their token sale contract was exploited by a hacker. The project appears to be completely inactive, and therefore it is assumed that no assistance will be provided for any affected users.
