> Use for malware distribution
>
> Since at least 2015, ACE archives have been used to deliver malware
> to victims by e-mail. This tactic was viable because popular
> archiving software was able to uncompress ACE archives, but support
> for the ACE format in security products such as mail filters, web
> content filters, and anti-virus software was generally weak.
>
> Security vulnerabilities
>
> In February 2019 several major security vulnerabilities were found
> in the unacev2.dll library which is used by WinRAR and other
> archiving products. Since WinACE support is discontinued, users are
> advised against opening ACE archives in WinRAR and possibly [other
> products][2] using this library. WinRAR stopped supporting ACE as of
> version 5.70, and similar products are following suit.
