                    The decentralized exchange increased margin requirements on several markets on Nov. 18, after an alleged targeted attack on the YFI token triggered massive liquidations. 
                    Decentralized crypto exchange dYdX has disclosed new measures to mitigate trading-related risks after burning $9 million of its insurance fund on Nov. 17 to cover users’ losses.According to an announcement on X (formerly Twitter), the exchange increased margin requirements on several “less liquid markets,” affecting tokens such as Eos (EOS), 0x Protocol (ZRX), Aave (AAVE), Algorand (ALGO), Internet Computer (ICP), Monero (XRM), Tezos (XTZ), Zcash (ZEC), SushiSwap (SUSHI), THORChain (RUNE), Synthetix (SNX), Enjin (ENJ), 1inch Network (1INCH), Celo (CELO), Yearn.finance (YFI), and Uma (UMA).dYdX triggered its insurance fund to cover users’ trading losses on Nov. 17 after a profitable trade targeting long positions on the YFI token caused the liquidation of positions worth nearly $38 million. dYdX founder Antonio Juliano dubbed the move a "targeted attack" on the exchange. According to him, YFI's open interest in dYdX spiked from $0.8 million to $67 million in a matter of days as a result of the actions of one individual. The same individual, according to Juliano, attempted to attack the SUSHI market on dYdX a few weeks earlier. "We did take action to increase initial margin ratios for $YFI prior to the price crash, but this was ultimately not sufficient. The actor was able to withdraw a good amount of $USDC from dYdX right before the price crash," he wrote. On X, the exchange’s team said that "highly profitable trading strategies have now been banned on dYdX,” in a reference to the language used by Mango Markets’ exploiter Avraham Eisenberg in his $116 million attack of 2022. dYdX is now offering a bounty payment in exchange for valuable information:dYdX will pay bounties to those most helpful in aiding the investigationWe will not pay bounties to, or negotiate with the attackerWe and others have made significant progress into identifying the attacker. We are in the process of reporting the information we have to the FBI— Antonio | dYdX (@AntonioMJuliano) November 19, 2023

The YFI token declined by 43% in just a few hours on Nov. 17 after soaring over 170% in November. The sharp decline wiped out over $300 million in market capitalization from the recent gains, according to data from CoinMarketCap. In the past 30 days, however, the token has still gained over 90%, trading at $9,190 at the time of writing.The Yearn.finance team hasn’t disclosed any official details about the incident. A source familiar with the matter told Cointelegraph that developers on the team do not control the majority of the token supply, strongly refuting initial concerns about a potential scam. The claim is supported by Etherscan data showing large centralized exchanges as YFI top holders.Magazine: Blockchain detectives — Mt. Gox collapse saw birth of Chainalysis

                    The security firm urges those using wallets generated from 2011 to 2015 to transfer their assets to crypto wallets that were generated more recently. 
                    While the crypto community is still weathering the effects of the recent $100-million Poloniex hack, another cybersecurity threat that could affect billions worth of crypto assets has been discovered by a team of blockchain security experts. On Nov. 14, cybersecurity company Unciphered released information on a vulnerability that they called “Randstorm,” which they claim to affect millions of crypto wallets that were generated from 2011 to 2015. Today we release our work on Randstorm: a vulnerability affecting a significant number of browser generated cryptocurrency wallets https://t.co/CebdytNaC6 Reporting @washingtonpost  https://t.co/OzYDq2tH4WTechnical write-up:  https://t.co/HPqjtaX1CA #Bitcoin #blockchain pic.twitter.com/aN7CZh9sv4— Unciphered LLC (@uncipheredLLC) November 14, 2023

According to the firm, while working to retrieve a Bitcoin (BTC) wallet for a customer, they discovered a potential issue for wallets generated by BitcoinJS and derivative projects. The issue could possibly affect millions of wallets and around $2.1 billion in crypto assets, according to the cybersecurity company. The firm also believes that multiple blockchains and projects could be affected. Apart from BTC, the company highlighted that Dogecoin (DOGE), Litecoin (LTC) and Zcash (ZEC) wallets could also potentially contain the vulnerability.

For those who are using crypto wallets generated within the 2011 to 2015 time frame, the company recommends transferring their assets to wallets that were generated more recently. They wrote: “If you are an individual who has generated a self-custody wallet using a web browser before 2016, you should consider moving your funds to a more recently created wallet generated by trusted software.”While the company said that not all impacted wallets are affected equally, it also confirmed that the vulnerability is exploitable. However, the company did not provide any details about the exploitation of the vulnerability to avoid providing more information to bad actors in the space.
