    Tldr. Update WinRAR.

    Better option, uninstall WinRAR and use something more sensible like 7zip.

      Better option: move to Linux, also dump rar

      I’ll just uh… Leave these here.

      https://www.tomshardware.com/tech-industry/cyber-security/wide-ranging-7-zip-vulnerability-with-8-8-cve-rating-allows-for-code-execution-hundreds-of-millions-of-machines-potentially-at-risk

      https://cybersecuritynews.com/7-zip-rce-vulnerability-exploited/ (another similar CVE from late last year)

      I use 7-zip myself, and have for over a decade, but it too has like… A major CVE around once every six months - worse than WinRARs record actually.

      Its no silver bullet.

        Not a silver bullet but the functionality of 7zip is far greater then WinRAR.

        A few people over time have sent me RAR files.

        When I ask them why, they always say they had downloaded or received a RAR file at some point, which they didn’t know what to do with until they looked it up and installed WinRAR to extract them. After that, they learned that RAR was better than ZIP for compressing files, causing them to use that instead of ZIP.

        I usually respond with 7-Zip is better than WinRAR in terms of compression, while still being able to extract RAR files, which doesn’t always win people over because these are non-technical people that are usually hesitant to install new software unless they actually need to.

        None of these people knew each other when they first started using WinRAR, so I think this is actually pretty common.

        Edit: with that being said, it probably happens less often now that Windows 11 can natively extract RAR files.

        Orgs who haven’t updated their processes in 20 years and still have a valid license.

          License? I thought the point was to see how high the number went every time you opened it.

      Most of the clippy pfp people won’t switch away from WinRAR, just like they won’t switch away from Windows 10 no matter how many vulnerabilities it gets

    Could have afforded more secure code if anyone had bothered to buy WinRAR instead of clicking through the nag screen every time.

      Why use it in the first place? To me that’s some ‘hi from 2000s’ kind of thing.

      Dumb and inefficient but simple enough to not care about your newfangled “security exploits”.

        Do you have any foundation for your claim?

        • tar paired with gzip or xz it is quite comparable in compression ratios. xz can be actually better than rar.
        • tar preserves file permissions.
        • tar lets you just pack files together with no compression at near instant speed
        • you can pipe it

        Dumb is a feature: do one thing and do it well. Inefficient? BS.

        Here a qick comparison

          tar has no index for quick lookup, tar extracts in quadratic time, stuff like that. I mean, even zip can extract a 1 MB file in a second from a 5 GB archive, tar needs to extract the whole thing.
          No “magic byte” either, making life hard for mime-tooling.

          To be fair, it was made for tape backups.

          • tar lets you just pack files together with no compression at near instant speed

          cat does so too. Add a index with metadata and a separator bit between the files and you almost have a tar but better in some areas.
