The hype surrounding NFTs has resulted in hundreds of millions of dollars in additional revenue for some of the world's most iconic brands, highlighting the mass consumer appeal of digital collectibles. The number of people exploiting this industry are on the rise in-parallel. Scammers continue to use a variety of methods to defraud crypto users of their NFTs, including phishing attacks, marketplace exploits, and others. Multiple reports from blockchain security and risk management organizations indicate that scammers stole more than $100 million in NFTs starting in 2021. Elliptic, a risk management firm, reported that, despite the market downturn, scammers stole the most tokens in July 2022, estimated to be 4,647 assets, and the most value in May 2022, estimated to be $23.9 million.
Sudoswap imitation disk Sudorare is presumed to have a rug-pull, with the $WETH and $XMON tokens in the contract address being moved to the perpetrator's address and then sold on Uniswap for ETH, making a total profit of about 519.5 ETH, or about $800,000 at the time the event happened. Multiple reports say that the initial deployment funds came from the exchange Kraken, and now neither the Sudorare website nor their Twitter account are accessible.
The KaoyaSwap, a BSC-chain decentralized transaction protocol based on AMM and exchange pools, was attacked, resulting in a loss of approximately 37,294 $BUSD and 271.2 $WBNB. The affected function considers the balance difference of the last pair before and after the swap as the amountOut, before transferring $BNB tokens to the user. This logic will not cause any issues if the last pair appears only once in the swap path. When the last pair only appears one or more times, it will miscalculate the amount that should be transferred to the user. As a result, the attacker devised a swap path that includes two self-constructed tokens, tokens A and B, with the swap path likely being [A, WBNB, B, A, WBNB], with the A and WBNB pair being included twice in this swap path. Later, the malicious actor borrows 1800 WBNB in a flash loan and adds liquidity to the [tokenA, WBNB] and [tokenB, WBNB] pairs. Then he gets 1019 WBNB after the swap and 1029 WBNB after the liquidity removal, leaving himself with the profit.
The Beijing municipal government announced a Metaverse innovation and development plan for the next two years, beginning in 2022 and mandating compliance with the recently issued Web3 innovation plan by all districts.

Integration of technical methods such as 3D visualization and GIS would be part of the development program to create a digital platform for visualizing urban areas and making suitable progress toward the design of digital native intelligent infrastructure.
