In this article, you will learn insights about malware attacks and know important tips to stay safe from these attacks.
Malware, short for malicious software, are programs engineered to gain unauthorized access to data, systems, and networks, paralyze their normal working operations or destroy them.
The malicious programs have been around for quite some time. And, a frequent internet user should not be alien to some of these programs.
Malware Attacks During COVID-19 Pandemic
There were several malware attacks in Q1 2020. The most recent one that stands out occurred during the peak of the COVID-19 outbreak.
The pandemic forced workplaces to become fully remote during this period, making many people work from home. Although remote work helped keep the spread of the virus low, it came with its disadvantages.
Soon after the lock-down, cyber-criminals start attacking both private and corporate networks.
The majority of these attacks come through home connections, which are usually not as secure as the ones in offices. And, they did this with the spread of emails, ads, and post links disguised to contain information concerning COVID-19.
Malware Variants in Android Applications
For example, in India and Canada, cyber-criminals developed cloned versions of the official COVID-19 tracer application set to be released by the respective governments to the public.
In India’s case, they infused the application with SpyMax, SpyNote, and Aymth – three commodities and open-source malware.
For the Canadian application, they made use of the CryCryptor ransomware. Luckily, these malicious applications were quickly detected, and their negative impact was soon curtailed.
Common “Household” Malware and How to Stay Safe from Them
These attacks, in their various forms, are pretty much “household” names. Outlined below are a couple of the common ones:
- Virus: These programs damage the core functionalities of a system.
- Worms: Just like actual worms, these programs replicate themselves on systems in a network.
- Spyware: These programs spy on what the user is doing.
- Trojans: They breach security and provide backdoor access for other malware.
- Ransomware: These hijack control of the system or network, the ransom demands for payment, and may unlock the system after receiving the payment.
Staying safe from this malware is just as important as knowing about them. Explained below are some safety tips:
- Use Anti-malware Software: Antivirus, anti-spyware and anti-malware software are some preventive programs that can be used to protect, scan, and detect any malicious program either trying to get in or already existing on the system.
- Use a VPN: This tip is most especially useful for organizations. Individuals can also improve security with a VPN as they encrypt network connections and prevent unscrupulous elements from stealing sensitive network credentials, gaining unauthorized access, and planting malware on the system.
- Employ Best Practices: Downloading email attachments from unknown senders, clicking unsafe links, downloading applications, and documents from untrusted sources are practices that should be avoided entirely. This reduces exposure to malware infections by a mile.
