1Password chrome extension - CallerCheck Exploit

Is the following process trace 'normal' for 1password? It seems since the v7 update, out our behavoir analysis (Sophos - Intercept X) is detecting this as an exploit (CallerCheck).

Has this been reported? Any ideas?

    Hi @dixie_tech,

    I've checked with our Windows development team and it looks like that's a false positive and should be reported to Sophos as such.

  • Ok, thanks. I have contacted sophos and they say it is exhibiting uncharacteristic behavior. They suggested white-listing the process if 1password confirmed the process trace was legit. Thanks again for the response.
