Malware is the short for malicious software, which is typically designed to steal data, infect systems, or spying. There are a wide range of malware used by hackers – worms, trojan horse, spyware, viruses, ransomware and more. Each one is specific and does a certain kind of harm. In this post, we are sharing more on malware, how to prevent malware attacks, and other details.
Common types of malware
Identifying different types of malware is one of the important steps in preventing an attack. It is important to ensure that employees are aware of malware and social engineering, so that they can be proactive in their approach. Here’s an overview of different types of malware –
- Ransomware – Encrypts systems and data, and hackers ask for ransom in return of decryption key.
- Aims to gather data from networked devices, for further misuse, without the knowledge of the user.
- Displays too many ads, prompting users to install apps or click links. Can be related to ransomware installation too.
- This kind of malware disguises itself a desirable app or program, and once downloaded, it infects other systems and networks.
- Replicates on a system on its own and spreads on the entire network that’s accessible.
- Malware designed to give remote control of a device.
- Malware that monitors keystrokes on the keyboard. There are keyloggers used for mobile devices too.
How to prevent malware attacks?
Here’s a quick summary of effective steps for preventing malware attacks –
- Change all default usernames and passwords.
- Create strong passwords.
- Recommend a password manager to employees
- Recommend safe browsing practices
- Share examples of phishing and adware
- Use firewalls for all networked devices
- Use network segmentation where necessary.
- Focus on using anti-malware software
- Update all software and firmware regularly

The need for access rights management
Ensuring that only right people have access to right resources at a given point and time is absolutely critical. Make sure that your company has established a system for adding, updating, changing, and removing access rights, especially for important accounts and privilege users.
Lastly, do train your employees on what it takes to find and avoid malware. Hire security experts, if needed, to explain the possible concerns. In case your company doesn’t have an incident response plan in place, make necessary policies and protocols. Also, get networks scanned and devices checked from time to time to identify possible signs of malware attacks.
