Protecting Your Systems from Instant Message Viruses and Spim

As instant messaging (IM) becomes an integral part of modern communication, system administrators must navigate the risks posed by viruses and spam within these platforms. While IM offers convenience, it’s also a prime target for cybercriminals, leading to the rise of instant messaging malware and spim (spam over IM). In 2023, the IM virus threat increased by 30%, with attacks becoming more sophisticated and harder to detect. Understanding these risks and implementing stringent protective measures can save systems from devastating breaches.

Here’s a guide to help you secure your organization's IM channels with a focus on facts, real-world scenarios, and the latest cybersecurity insights:

1. Exercise Caution: Verify Before You Act

Imagine this: a user receives a message from a colleague with a seemingly harmless file attached. Without verifying, they open the file, inadvertently launching a malware attack that quickly spreads across the network. This scenario is more common than you’d think. Reports show that 70% of IM-based cyberattacks originate from unsuspecting users accepting malicious files. As a system administrator, it’s essential to educate users to never open or download files from unknown senders in IM. Implement policies that enforce verification of sender identities through alternative channels such as email or phone calls.

2. Always Confirm with the Sender

In today’s world of sophisticated phishing tactics, attackers can impersonate trusted contacts, sending infected files that appear legitimate. Before accepting a file, especially from an unfamiliar sender, confirm its legitimacy using a secondary communication method. This extra step could prevent a network-wide compromise. A recent cybersecurity survey revealed that 63% of data breaches were a direct result of users unknowingly opening malicious attachments.

3. Regularly Update Software to Patch Vulnerabilities

Cyber attackers often exploit vulnerabilities in outdated software, including instant messaging platforms. Regular updates are non-negotiable. In 2022, more than 80% of successful IM-based attacks occurred on systems running outdated versions of software. To combat this, ensure your operating system, IM software, and antivirus programs are up to date with the latest security patches. This simple practice can drastically reduce the attack surface available to hackers.

4. Leverage Built-In Security Features

Modern IM software is equipped with robust security features like attachment scanning, encryption, and blocking of known malware. However, many users and system administrators fail to utilize these tools to their full extent. Encourage the use of secure messaging platforms that offer end-to-end encryption and advanced security features like automated attachment scanning, which can block over 90% of known malware before it reaches the user.

5. Stay Vigilant Against Spim: The IM Version of Spam

Just as email spam (phishing) targets unsuspecting users, spim (spam over IM) is on the rise, often carrying harmful links or attachments. In 2023, spim attacks rose by 20%, with attackers using IM to deliver malware or direct users to phishing sites. Train users to avoid clicking suspicious links or accepting messages from unknown contacts. Many attackers rely on curiosity or urgency to trick users, so proactive training and blocking unknown senders is critical in reducing risk.

6. Install Reputable Antivirus and Antispyware Programs

An organization’s first line of defence against IM viruses is antivirus and antispyware software. While this may seem basic, nearly 50% of organizations targeted in IM-based attacks lacked up-to-date antivirus software, leaving systems vulnerable to exploitation. Implement enterprise-grade antivirus programs that include IM virus detection capabilities and make regular updates mandatory. A strong antivirus program can detect and remove malicious IM attachments before they cause harm.

7. Utilize Windows Defender for Extra Security

For organizations relying on Microsoft-based systems, Windows Defender offers reliable, built-in protection against spyware and malware threats. System administrators can ensure that Defender is activated and configured to provide real-time scanning and automatic updates. In a recent report, Windows Defender blocked over 15 billion malware threats in 2022 alone, demonstrating its capability to prevent IM-based malware infections.

Conclusion: The Growing Threat of IM Attacks and How to Counteract Them

System administrators are on the front of defence against instant messaging-based cyberattacks. The increasing frequency and sophistication of IM viruses and spim underscore the need for vigilance and best practices. Implementing strict security protocols, regularly updating software, and educating users about the risks associated with IM platforms will strengthen your organization’s cybersecurity posture.
