How malware works
Malware is designed to infect a computer and then perform various malicious actions. After exploiting technical or human vulnerabilities in the environment, an attacker delivers malware to hack into your users’ computers with the aim of stealing or denying access to information and systems. Antivirus fights malware by identifying them against known types and removing them. While antivirus is still useful for preventing basic malware, it is insufficient for detecting the more common evasive and advanced malware samples seen today. This is because they rely on human or automated systems to find a database.
In fact, modern malware is better than ever, capable of changing the way it looks to evade detection used by antivirus. Using methods that criminals call “packing and encrypting,” attackers can repeatedly modify a core malware file. Although the malicious executable still does exactly the same, it looks like a new file. Because of this, antivirus will not detect it.
CDR as a solution
The solution can be found in CDR technology, as Gartner’s recent Hype Cycle report shows that CDR is a high priority as additional network security. CDR is the necessary complement to antivirus. It is built for the current threat landscape. It ensures that malicious content (such as macros, embedded objects and actions) is removed from files. All this is done without affecting the usability and appearance of the file. The user himself does not notice it. The purpose of CDR is the same as that of antivirus, which is to prevent files with malware from causing damage. It does work in a different way. Unlike antivirus, it does not preemptively scan for the presence of known malware, but proactively removes all potentially malicious content from the file immediately.
