Fact Check: Are MP4 files safe?

Conclusion

Verdict: Partially True

The claim that MP4 files are safe from malware is partially true. While MP4 files themselves are not executable and do not inherently contain malware, there are documented vulnerabilities associated with the format that can be exploited through maliciously crafted files. Key evidence supporting this verdict includes the existence of multiple vulnerabilities listed in the Common Vulnerabilities and Exposures (CVE) database, as well as specific cases where software processing MP4 files has been compromised, such as the WhatsApp vulnerability.

However, it is important to note that the risk of encountering malware through MP4 files is largely dependent on the software environment in which they are used. Outdated media players and lack of robust security measures can increase the likelihood of exploitation. Thus, while the file format itself is not a direct threat, the context of its use can pose risks.

There are limitations in the available evidence, particularly regarding the frequency of such attacks in real-world scenarios. Most sources emphasize the importance of maintaining updated software and using antivirus tools, but they do not provide comprehensive statistics on how often MP4 files are actually used as vectors for malware. This uncertainty highlights the need for caution and vigilance when handling any file type, including MP4s.

Readers are encouraged to critically evaluate information regarding digital security and to remain informed about the potential risks associated with various file formats.
