Before running a capture you can select the type of interface you want to monitor. With Wireshark you can sniff traffic to identify infected files, helping you to find the root cause of a virus outbreak. Wireshark is a packet sniffing tool available for Windows, macOS, and Linux that you can use to scan your network for malicious traffic. How to scan for malicious traffic with a packet sniffer (Wireshark) To detect a network virus a network administrator needs to scan network traffic with a packet sniffer or intrusion detection tool to detect malicious packets and other suspicious activities. The side effects of a successful attack range from poor network performance to data theft, compromised device performance, and downtime.įrom a network administrator’s perspective, Network viruses require a different type of security strategy than traditional viruses. Such viruses are very difficult to get rid of and commonly re-infect devices. Unfortunately, the process is a little more complex when dealing with a network virus.Īs network viruses spread through network packets, traditional antivirus solutions can’t detect them. Once a virus is detected the user can quarantine the files and remediate the outbreak. Network viruses are different from traditional viruses because they don’t rely on files in order to spread but self-replicate across hosts and spread through executable code or a document.įor most viruses, administrators can deploy an antivirus solution that runs manual or automated scans to detect when a device is compromised. What is a ‘network virus’ and how is it different from a normal virus?Ī network virus is a type of malware that can replicate itself across multiple computers through network packets. With the emergence of network viruses that spread through network traffic, administrators have to be even more proactive at detecting threats. The cost of downtime can be devastating, with the infamous MyDoom virus costing $38 billion over 15 years, becoming the most high profile virus to date. Knowing how to perform a network virus scan is essential for identifying the latest cyber threats and avoiding downtime. Accidentally clicking on a fake link is all it takes to infect your network with malware of a virus. For years, viruses have remained a persistent threat to enterprises of all sizes.
