Apple released new operating system versions (iOS 14.7.1, iPadOS 14.7.1, and macOS Big Sur 11.5.1) which include a fix for a zero-day exploit. BGR posted information about the update. The vulnerability gave an application to “execute arbitrary code with kernel privileges.” In other words, gaining access to the kernel means you own the device. For mobile devices, apply the update by navigating to Settings -> General -> Software Update. For Mac users, go to Apple…
I nearly fell off the bar stool (actually, it was a desk chair) when I saw the Bitdefender post about the percentage of Twitter users that have enabled two-factor authentication (2FA). It is just amazing that more users don’t configure 2FA (or MFA) to protect their accounts. Especially given that 2FA typically doesn’t cost any money and is shown to stop over 99% of credential-based account attacks. Apparently, Twitter users have taken the non-compliance percentage…
Gmail is the most used email service in the world. Many of us have a Gmail address even if we primarily communicate via a business email address. The last thing you want is to contract a virus or inadvertently delete your account and have all your email vanish into the ether. The obvious solution is to backup your messages. TechViral has a tutorial with simple steps to backup your Gmail email. The first step is…
When it comes to updating software, don’t forget about other devices such as printers, monitors or router firmware. Case in point – SentinelLabs has discovered a 16-year-old vulnerability that has existed in a vulnerable printer driver for millions of HP, Samsung and Xerox printers. The vulnerability is a buffer overflow (CVE-2021-3438) in the SSPORT.SYS driver for specific printer models that could lead to a local escalation of user privileges. The list of impacted printers includes…
If your business or home Wi-Fi network doesn’t currently support the latest encryption standard of WPA3, now would be a good time to upgrade. To take advantage of the increased security, connecting devices also need to support WPA3. Many modern smartphones running current versions of the operating system currently support WPA3 networks. According to a PCWorld post, the next version of Windows 10 (version 21H2) will also support the WPA3 standard. Here’s a list…
The word of the day is ransomware. It is no secret that ransomware attacks are on the rise. The news is filled with stories of attacks demanding millions of dollars in ransom to restore systems. But ransomware attacks are impacting small business users too and not just the mega companies like Colonial Pipeline. One of the first lines of defense against ransomware attacks is a good backup. KrebsonSecurity has posted information to help you avoid…
Automated updates and installations are a good thing, especially given that most users don’t tend to apply updates in a timely fashion. If you are a Windows 10 user, the Windows 11 upgrade will automatically be delivered later this year (assuming your hardware supports it). But what if you are happy with your Windows 10 installation and aren’t ready for the changes Windows 11 brings along? PCWorld revealed that Microsoft will allow you to easily…
We have to do a better job dealing with passwords. TechRepublic posted some results from a password practice survey of over 1,000 professionals conducted by Beyond Identity and it is not a pretty picture. As a summary, almost half of respondents admit to sharing passwords while more than a third write their passwords on paper. The lesson for employers is that one in four still have access to login credentials from previous employment. Password reuse…
Ever want to know how many days there are from a certain date? How about finding out what the 137th day of the year is? You can always ask Google or do some date calculation with Microsoft Excel. How-To Geek has a post with instructions to perform date calculations. The basic principle is to create three columns for the date calculations. In the first column, put in your base date such as a due date…
Many of us use an external USB device to augment our computer storage or as a backup device. Last week, BleepingComputer reported that Western Digital My Book NAS devices were being factory reset with all of the files being deleted. Originally, it was thought that the problem was related to a 2018 vulnerability. Not so fast. Ars Technica posted a more detailed analysis of the “disappearing data” from My Book Live devices. To make matters…
