Microsoft on Thursday warned thousands of its cloud computing customers, including some of the world's largest companies, that intruders could have the ability to read, change or even delete their main databases, according to a copy of the email and a cyber security researcher. The vulnerability is in Microsoft Azure's flagship Cosmos DB database. A research team at security company Wiz discovered it was able to access keys that control access to databases held by thousands of companies. Wiz Chief Technology Officer Ami Luttwak is a former chief technology officer at Microsoft's Cloud Security Group. Because Microsoft cannot change those keys by itself, it emailed the customers Thursday telling them to create new ones. Microsoft agreed to pay Wiz $40,000 for finding the flaw and reporting it, according to an email it sent to Wiz. "We fixed this issue immediately to keep our customers safe and protected. We thank the security researchers for working under coordinated vulnerability disclosure," Microsoft told Reuters. Microsoft's email to customers said there was no evidence the flaw had been exploited. "We have no indication that external entities outside the researcher (Wiz) had access to the primary read-write key," the email said. “This is the worst cloud vulnerability you can imagine. It is a long-lasting secret,” Luttwak told Reuters. “This is the central database of Azure, and we were able to get access to any customer database that we wanted.” Luttwak's team found the problem, dubbed ChaosDB, on Aug. 9 and notified Microsoft on Aug. 12, Luttwak said. The flaw was in a visualization tool called Jupyter Notebook, which has been available for years but was enabled by default in Cosmos beginning in February. After Reuters reported on the flaw, Wiz detailed the issue in a blog post. Luttwak said even customers who have not been notified by Microsoft could have had their keys swiped by attackers, giving them access until those keys are changed. Microsoft only told customers whose keys were visible this month, when Wiz was working on the issue. Microsoft told Reuters that "customers who may have been impacted received a notification from us," without elaborating. The disclosure comes after months of bad security news for Microsoft. The company was breached by the same suspected Russian government hackers that infiltrated SolarWinds, who stole Microsoft source code. Then a wide number of hackers broke into Exchange email servers while a patch was being developed. A recent fix for a printer flaw that allowed computer takeovers had to be redone repeatedly. Another Exchange flaw last week prompted an urgent U.S. government warning that customers need to install patches issued months ago because ransomware gangs are now exploiting it. Problems with Azure are especially troubling because Microsoft and outside security experts have been pushing companies to abandon most of their own infrastructure and rely on the cloud for more security. But though cloud attacks are rarer, they can be more devastating when they occur. What's more, some are never publicized. Learn more by visiting OUR FORUM.

If you notice you’re having network & internet connection problems on your Windows 10 or Windows 11 PC. Issues like Unidentified network appearing, the Wi-Fi connection is limited, low Wi-Fi signal strength or the WiFi adapter is not working at all, then this post is intended to help you with solutions to the issue.
Why won’t my Windows 10 let me connect to WIFI?
Typically, your Windows 10/11 computer won’t connect to a network if Wi-Fi has been disabled on the device. Power-cycling or a simple reboot of your internet device (modem and router) usually fixes most network connectivity problems. Unplug your modem and router from the power socket, wait a minute, plug in your modem, wait a minute, and then plug in your router.

How do I know if my wireless adapter is bad Windows 10/11 ?
To know if your wireless adapter is bad, simply open Device Manager on your Windows PC. Expand the Network adapters section, and If there’s an exclamation or question mark beside the wireless adapter, then you have a wireless problem; if not you’re OK. But if your wireless adapter is still not working, then the solutions below can help you.

Install a VPN and you might think your internet activities are fully protected from snoopers. With every site you access, all the data you transfer is sent through the VPN's secure encrypted tunnel and so keeping it safe from prying eyes. Unfortunately, if the VPN connection fails (e.g. server problem, weak Wi-Fi signal, overloaded network, etc) then your device may switch to your regular unprotected connection. Sites then get your real IP address, Wi-Fi hotspots might see the websites you're accessing, and the VPN won’t be encrypting any of your data. Most VPN providers handle this situation by offering a kill switch - although some give it a different name, like ExpressVPN's Network Lock or Windscribe's Firewall. But is this an effective solution? In this article we'll explain what a kill switch does, the different types of kill switches available, and how you can make sure your VPN kill switch is set up correctly. The idea behind a kill switch is simple. Essentially, if the VPN connection drops, the kill switch activates and blocks your device's internet access. This prevents you from accidentally sending data outside of the secure VPN tunnel, because if the tunnel fails then you won't be able to send any data at all. Every platform has its own tools for making this happen. An Android VPN app might use Android's built-in 'Always-on VPN' setting, for instance (Settings, Connections, More Connection Settings, VPN.) But Windows VPNs often use the Windows Filtering Platform (the technology behind Windows Firewall), and Mac and iPhone VPN apps have further techniques of their own. If the VPN drops, then however the kill switch kicks in, your VPN app usually tries to reconnect. Once the tunnel is up again, your internet access is automatically restored. As an aside, all this cross-platform complexity makes it challenging for VPN providers to offer a kill switch on every device type. Keep that in mind if you visit a provider's website and it boasts about having a great kill switch but doesn't list the supported platforms. Check the rest of the site, maybe in the Support pages, to find out if there's a kill switch on all apps. Although the concept of a kill switch is simple, the reality is more complicated, because every provider and app has its own way of working. There are two common approaches. The most popular type, such as ExpressVPN's Network Lock on Windows, only blocks your internet access if the VPN drops unexpectedly. If you manually disconnect or close the VPN app, the kill switch is disabled and you're free to browse as usual. But others (including NordVPN's Windows app) don't allow any internet access at all unless you're connected to the VPN. If you manually disconnect or close the app, you won't be able to get online until the VPN connection is re-established. This technology monitors your system, and if it detects a dropped connection, closes the apps you specify. You might tell the VPN app to shut down your browser and torrent client, for instance, ensuring they won't use an unprotected connection. Application-level kill switches don't offer much security. But they're also less likely to get in your way than the usual type, as they only affect the apps you specify and won't block anything else. If you only need the most basic protection for one or two apps, an application-level kill switch might be useful. But if you're looking for something more comprehensive, we'd stick with a system-wide kill switch. For more on this visit OUR FORUM.
