Unsafe Virtual Playgrounds: The Inadequacy of Sandboxing in Today's Digital Environment
In the ever-evolving landscape of information technology, the methods used to safeguard digital assets are constantly being refined. Two such techniques, file disinfection and sandboxing, have become cornerstones in the fight against malware.
Sandboxing is a method in IT security where potentially dangerous files are tested in a special, isolated environment. This allows for the analysis of files without risking the integrity of the main system. However, the tactics of malware have evolved, and sandboxing is no longer a real barrier for Trojans, viruses, or other malicious code.
Malware can delay execution to avoid detection during sandbox analysis, go into a kind of "sleep mode" for a certain period, or even check for certain characteristics to determine if it might be in a sandbox. To counteract this, cybercriminals often divide or fragment malware into multiple packages that appear harmless individually, making it difficult for sandboxing to detect them.
File disinfection, on the other hand, involves converting dangerous file types with high risk potential into harmless ones. This method can be used standalone or in combination with an anti-malware multiscanner. The OPSWAT anti-malware multiscanner solution, for instance, allows the use of up to 35 anti-virus scanners in parallel, significantly increasing the chances of detecting and disinfecting malicious files.
The parallel use of multiple scan engines in an anti-malware multiscanner solution makes it increasingly difficult for complex malware to find a loophole. Moreover, unknown viruses with signatures, such as those in zero-day attacks, can be reliably disinfected using this method. Detection rates of over 99.7% do not guarantee 100% security, but when combined with file disinfection, even zero-day attacks and the latest malware technologies can be reliably stopped.
Companies and organizations can benefit from defense and filter technologies from various vendors by using file disinfection. Password-encrypted file attachments that can't be automatically opened in the sandbox are used by criminals, particularly in phishing emails. By employing file disinfection, these threats can be neutralised before they pose a risk.
In the automotive industry and certain engine control systems, there is a similar concept to sandboxing. They detect if a vehicle is on a test stand, akin to how malware can detect if it's in a sandbox. This shows the widespread applicability of these security measures.
Robert Korherr, the Editor-in-Chief and CEO of ProSoft GmbH, has been at the forefront of these advancements, continually pushing for improved security measures in the digital world. As the threat landscape continues to evolve, so too will the methods used to combat it, ensuring that our digital assets remain secure.
