7. SlowMist: Security personnel discovered a new vulnerability in iOS 16 and reminded cryptocurrency practitioners not to use jailbroken devices
SlowMist Chief Information Security Officer 23pds tweeted that cybersecurity researchers have discovered a new post-exploitation persistence technique in iOS 16: Even if the victim's Apple device is offline, the technique can be used to quietly access the device. This vulnerability is only possible on devices that have been exploited or jailbroken. Attackers trick victims into thinking that their device's airplane mode is working properly, when in fact the attacker has implanted a fake artificial airplane mode after successfully exploiting the device, which edits the user interface to display the airplane mode icon and cuts off the Internet connection for all applications except the attacker's application. SlowMist reminds cryptocurrency practitioners not to use jailbroken devices for convenience.

9.Curve proposes to disable Chainlink restrictions in all crvUSD price oracles
Curve publishes a proposal to disable Chainlink restrictions on crvUSD price oracles. The proposal states that currently Chainlink implements a +/- 1.5% "safety limit" on all crvUSD price oracles. This means that if the Chainlink price deviates too much (1.5%) from the internal oracle price (EMA), it will use Chainlink's source. When the market is volatile, Chainlink prices can cause unnecessary losses. If volatility is high enough, price oracles using Chainlink restrictions may still deviate. Therefore, it is recommended to disable Chainlink restrictions in the price oracle contracts of all markets, except for the old frxeth market (which will be replaced by the new market soon). The specific method is to call set_use_chainlink(False) in all price oracle contracts of the ControllerFactory owner (ownership DAO).

Sources said this indicates that the SEC will not block the launch of such funds within a few weeks.
