Many industries and companies allow – and even encourage – users file downloads. Whether it is health coverage, a mortgage or a Assurance policy, sometimes file downloads are essential. However, these file downloads should be treated with caution as they contain inherent risks. Read on to learn about some of the file download vulnerability mistakes you make, best practices for preventing file download attacks, and why developing a secure file download system is essential to prevent data breaches. expensive.
Are you making file download vulnerability errors?
Hackers have learned that it is not always easy to breach corporate cyber defenses. instead, they found an easier way to inject malicious code in a target – by detecting a file download vulnerability and embedding malicious content in downloads. This means that every time a customer, vendor, or other third party downloads a file to your system, your entire network is at risk of being exploited. Hackers can easily identify organizations with file download vulnerabilities. How? ‘Or’ What? Here is a list of common mistakes.
Error 1: You are lacking authentication and authorization
It’s all about permissions. The Pirates can easily find a file upload vulnerability where there is no authentication or authorization check before a file can be uploaded, opening a door that allows malicious actors to unload any files they want . To avoid this scenario, make sure that the user has been authenticated by logging in, preferably using a user authentication protocol such as two-factor authentication, which combines the login details with another user action. security as a security token. This is to ensure that the user has the correct permissions to download a file to your system in the first place.
Error 2: you are entering your files incorrectly
Hackers can modify the file’s metadata to get the results they want. A changed file name or path can cause an application to change document security settings, overwrite a critical file, or run malware on the network. Make sure to validate and clean up a file’s metadata before allowing it to be downloaded.
Error 3: you are not checking the contents of your file
Checking the file name is not enough. You should also investigate the contents of the file. The contents of the downloaded file may contain all kinds of malicious scripts which can wreak havoc in an organization. Make sure that every downloaded file is scanned with anti-malware tools. Note that not all tools are created equal. Anti-virus scanners may be missing new or zero-day threats that threat detection engines have not yet classified. Some anti-malware tools cannot scan specific file types like PDF files or image files. Other anti-malware tools are unable to scan for embedded objects that might be lurking in a downloaded file. Make sure you choose the best anti-malware tool for your needs.
Error 4: You are storing files in a publicly accessible location
Many organizations make the common mistake of storing their files in a subsection of their website, such as the Media directory. This makes it very easy for attackers to locate and target these files. The downloaded files should be stored in external directories outside of the website root, which will prevent hackers from accessing these files through a website URL.
Error 5: You are not limiting certain file types
Certain types of files should never be allowed to be uploaded to an organization’s network because they can execute commands and execute malicious code. For example, .php, .exe, and .bat files should be refused and rejected as a file download. Better yet, use an allow list system that only allows certain types of files to download, as the deny list might miss an extension and be exploited.
Prevent file download vulnerabilities with Votiro
Unfortunately, even when these five file download vulnerabilities are addressed, hackers can still have the upper hand when it comes to finding ways to push malicious code beyond your organization’s file security. Take a zero trust approach to file downloads – don’t trust a single file or file item before it’s uploaded to your environment – is the only answer.
The API of Votiro first Disarmament and content reconstruction The Secure File Gateway solution first scans files for their true type, making sure that the extensions and other meanings match what the file actually is. Then the Secure file gateway distinguishes only the safe elements of each file, rebuilding a new file with known safe content and delivering that file to the final destination. Malicious code is proactively removed without scanning, detection, and blocking! Our secure file gateway scans all types of files, from ppts, documents, PDFs and images, to more complex formats like Autodesk files that virus scanners or other anti-malware tools could never detect.
