There are major vulnerabilities in many of the archivers that we use everyday, according to Cert-Fi. If you use any archiver at all, it’s best to go and download a new version. Surprisingly, the default zip compression in Windows Explorer doesn’t seem vulnerable. How do you like that – Microsoft having a product that is more secure than others! It’ll probably snow today in Sahara.
Some of the antivirus tools are also vulnerable, so better get yours updated too.
