From 27 February 2023 to 5 March 2023, all security incidents that had occurred were Security Hacks.
SECURITY HACKS:
1. Hacker Exploits SwapX’s Lack of Proper Validation for Access Control
On 27 Feb, a hacker attacked SwapX, an application deployed on the BNB Chain, by leveraging on a vulnerability in the implementation where it lacked proper validation for access control.
Here is how the attack was carried out:
Step 1: the attacker swapped 0.0581 BNB for 1 Million DND tokens.
Step 2: the attacker called the attacked contract’s 0x4f1f05bc function to swap the BUSDs of other users who had approved the contract’s spending for DNDs.
Step 3: the attacker repeated step 2 and swapped 1 million DNDs for 739.6 WBNBs.
The attacker repeated this process and eventually exploited crypto assets worth around US $1 million in this incident.

9. Goofy Gophers Mining Club Announced Hack on Discord Server
On 5 Mar, an NFT project deployed on the Cardano Blockchain Goofy Gophers Mining Club (@GGMC_nft) announced on Twitter that their Discord server was breached.

The links were ETH scams where Metamask wallets would be drained when accessed.
In a later update, Goofy Gophers Mining Club announced that the Discord is now fully back under the project’s control. Moving forward, they will be limiting the permissions of the teams’ ‘hot’ accounts. They have also asked users who were affected to “reach out to the team”.
