Hijacker Exploits EOS Networks and Makes Away with $120, 000 Worth EOSPlay

A cybercriminal exploited a network vulnerability on EOS and rolled out a consistent and accumulating 30,000 EOS in favor of himself, every-time he plays. This created a very dull day for EOS gambling on the app display.  The amount of EOS is worth $120, 553 at press time. Nevertheless, the attacker took advantage of REX to complete blocks with EOS transactions.


Hence allowing him to win continuously. Full blocks left the network in an unusable condition, since it froze other users to not be able to participate. This paved the way for the attacker to win thousands of EOS with a meager stake of only 300 EOS. Additionally, REX increased the cost of running the CPUs, as a result of which many participants did not afford and therefore remained locked out of the system for a while.


Eventually ending up rewarding the attacker. 


Attacker Monopolized EOS Network Control 

The attacker allocated 900, 000 EOS to CPU ensuring that anyone with a lower stake had no access to the network and couldn't participate in the gambling.  The CPU figure was extremely far away from what users could afford so as to gain network access. Meanwhile, the attacker was able to take full control of the network and steal thousands of EOS tokens.


Jared Moore, an EOS community member noted that other attackers could; still exploit the network since the weakness would persist until developers forked or patched the network. Furthermore, according to a smart contract developer and the developer of ERC-233, the attack could be worse than just any EOSPlay congestion.

For instance, the developer states, the attackers explored several differeHijacker Exploits EOS Networks and Makes Away with $120, 000 Worth EOSPlaynt smart contracts on the EOSIO network, popular for smart contract deployment. Therefore, anyone that stakes 300 EOS could still exploit the vulnerability for a while. 


Also, note that the owners of the hijacked smart contracts are not able to halt the process since the network is already congested; moreover, they can't even stake enough EOS to take control of the network.
