AMD and Microsoft Launch Fixes for Ryzen slowdowns in Windows 11
According to an AMD knowledgebase post published recently-, both Microsoft and AMD have provided fixes to solve AMD Ryzen performance problems found in early versions of Windows 11. According to AMD, a fault in Windows 11 might impair Ryzen CPU performance by up to 15%. AMD has published a new chipset driver to remedy a problem that affected the “preferred core” function, which can improve performance on high-core-count, high-TDP Ryzen CPUs. Even if you’re not affected by this problem because you’re using Windows 10 or a Ryzen CPU with fewer cores, the updated driver includes solutions for several additional Ryzen and Threadripper computers running Windows 10 or Windows 11. According to Microsoft, if you don’t already have the patch installed on your PC, it will show as an optional update in Windows Update for Windows 11 Home and Pro users. Otherwise, the update should be included in the next Patch Tuesday package automatically.

Hackers Continue to Steal Cookies from High-profile YouTube Accounts
Since late 2019, a group of hired hackers has been hijacking YouTube producers’ channels, forcing them into phony partnerships involving cryptocurrency scams or extortion. According to a recent analysis from Google’s Threat Analysis Group (TAG), cookie stealing malware was used to target the video platform. The breach was carried out by a gang of hackers who were recruited through a Russian-language forum.
Since May, Google has banned 1.6 million messages and restored roughly 4,000 YouTube influencer accounts damaged by the social engineering effort, with some of the stolen channels selling for anywhere from $3 to $4,000 on account-trading markets, depending on the subscriber count. Other channels, on the other hand, were rebranded for cryptocurrency scams in which the adversary live-streamed videos promising cryptocurrency giveaways in exchange for a small donation, but only after changing the channel’s name, profile picture, and content to imitate large tech or cryptocurrency exchange firms. Following Google’s involvement, the perpetrators have been seen directing targets to messaging applications such as WhatsApp, Telegram, and Discord to get around Gmail’s phishing defenses, as well as switching to other email suppliers such as aol.com, email.cz, seznam.cz, and post.cz. To avoid account takeover threats, users should use two-factor authentication.
