The security community is warning users of smartphones that hackers are developing fake COVID-19 apps that load ransomware on devices. These apps claim to provide information relevant to the COVID-19 outbreak but in reality, malware is installed onto the device.
Fake COVID-19 apps
According to information security provider ZScaler, hackers have been preying on people’s fears of the coronavirus by creating apps with features too good to be true. One such fake app claims to notify users as soon as anyone infected with the virus is nearby. The app locks the victim’s phone and demands for a ransom to lift the encryption.
Fake purchasing apps
Another app, claims to tell you where to buy N-95 masks. This is a hoax – the moment a user downloads and installs the app, it attempts to corrupt or encrypts data on your smartphone or laptop. Some versions of the app then ask for bitcoin deposits to unlock the data.
The security company, Lookout, identified an application that is essentially a copy of the legitimate coronavirus tracker maintained by Johns Hopkins University. However, this copy installs Trojan malware when the user installs the application.
Fake COVID-19 emails
Fake mobile apps are not the only thing threatening users – emails on the subject of the coronavirus have also become another outlet for malware. Emails with document attachments claiming to have a list of precautionary measures against the infection can be phishing attempts warned Quick Heal Security Labs director Himanshu Dubey.
“We see links or attachments that deliver information-stealing malware which can steal the person’s website and bank credentials,” Dubey told ETtech.
COVID-19 and the hacking problem
Cyber attackers have become very good at latching on to any local or global event once it gains traction. It is therefore vital that users double-check emails and applications they intend to install for obvious signs of them being a hoax or known malware.

Windows 11 Upgrade - Will it work on your lapop?
So, you’re wondering about Windows 11, the latest version of Microsoft’s operating system. It looks snazzy and has some neat features. But can your current laptop actually run it? Don’t worry, you don’t need a degree in IT to figure this out! We at abacon IT in Cape Town are here to help you understand the basics.
Upgrading your laptop to Windows 11 can give it a new lease on life. However, Windows 11 has certain system requirements. These are the minimum specifications your laptop needs to have to run the software smoothly. Think of it like needing the right ingredients for a recipe – without them, it just won’t work properly.
One of the most important parts is your laptop’s processor, often called the CPU (Central Processing Unit). This is the “brain” of your computer. Windows 11 needs a fairly recent and capable CPU to function well.
Which Processors Work with Windows 11?
Here’s a simplified look at the processors that are generally compatible:
Intel Processors:
- Generally, Windows 11 requires an 8th-generation Intel Core processor or newer. You might see names like “Intel Core i5-8xxx” or “Intel Core i7-11xxx.” The first number after the “i” (or “i3”) usually indicates the generation. So, an “i5-8250u” is an 8th-generation processor.
- Intel also has its Pentium and Celeron processors. For Windows 11, only certain newer models are compatible.
AMD Processors:
- For AMD, Windows 11 requires Ryzen 2000 Series and newer. You’ll see names like “AMD Ryzen 5 2xxx” or “AMD Ryzen 7 5xxx”. Again, the first number after “Ryzen” indicates the series.
- AMD also has Athlon processors. Similar to Intel’s Pentium and Celeron, only specific newer Athlon models will work with Windows 11.
Important Note: This is a general guideline. There can be exceptions, so it’s always best to double-check your specific processor.
How to Find Out Which Processor Your Laptop Has
Don’t fret, Windows makes it pretty easy to see what CPU is inside your laptop:
- Right-click the Start Button: This is the Windows logo (usually in the bottom-left corner of your screen).
- Select “System”: A new window will pop up with information about your computer.
- Look for “Processor”: You’ll find this listed under the “Device specifications” section. It will tell you the name of your processor, including the manufacturer (Intel or AMD) and the model number, which usually indicates the generation or series.
Once you have this information, you can compare it to the general lists above.
Other Important Bits for Windows 11
Besides the processor, there are a few other things Windows 11 needs:
- RAM (Random Access Memory): Consider this your laptop’s short-term memory. Windows 11 requires at least 4 gigabytes (GB) of RAM. More is always better for smoother performance. Instead, consider 16 gigabytes (GB).
- Storage: To install Windows 11, you’ll need at least 64 GB of free space on your hard drive or SSD (Solid-State Drive). An SSD generally makes your computer much faster.
- TPM 2.0 (Trusted Platform Module): This is a security feature. Most modern laptops have this, but it’s worth checking. You can usually find information on how to check for TPM 2.0 in your laptop’s BIOS settings (you might need to consult your laptop manufacturer’s website for instructions on accessing this).
- Graphics Card: Your graphics card needs to be compatible with DirectX 12 or later with a WDDM 2.0 driver. Most reasonably recent graphics cards will meet this requirement.
- Display: You’ll need a screen with a resolution of at least 720p (HD).
