back to article Fun fact: If you noticed a while ago Zoom's web client going AWOL for a week, it's because someone found a passcode-cracking hole

Zoom has confirmed it fixed a vulnerability that could have been exploited by miscreants to crack the passcodes needed to access strangers' private chin-wagging. The video-conferencing biz said it addressed the weakness in its systems after the issue was discovered and privately reported by UK-based bug-hunter Tom Anthony. To …

    Short visits, last week

    Zoom meeting last week supposedly only accessible for a group of registered people. There were second-long appearances with funny names like Sn00p3r. Has anyone observed similar things?

      Not when using the waiting room functionality.

      Mind you the big problem with Zoom is that it seems the passcodes are per user not per meeting - hence why the use of the waiting room functionality is essential.

      I think that's an old one and a user problem.

      1) User generates six digit passcode for meeting as described.

      2) User posts on farcebum or tw@ter "Iz joins heer for meet kids on Thu zoom 123456".

      3) Bored git sees post and has their willy make an appearance in said meeting.

      The fundamental security hole in Zoom is that it allows unvalidated attendees. If it were a "these email addresses and this passcode to join" thing, there'd be no problem. Unfortunately, lusers really like that "all u needs is my codes and is go heer" functionality and Zoom would be shooting their service in the head if they tightened things up.

    Two issues...

    First, the fact that there wasn't a delay... (Common practice for most of this century)

    Second... This activity should have caused a monitor to flag the offending IP address launching these requests for a single meeting and then drop that IP address at the firewall for at least 24 hours and file an automated report.

    Both fairly simple to implement.

    I see several stories a week about holes in Zoom. I was astounded to read an article that Princess Anne was teaching HRM how to use Zoom. With all of the tabloids gunning for the Royals, Zoom is probably a really bad idea for them to use.

    Get the very basics down

    These guys look like they took lessons from Microsoft regarding security...

    Whatever happened

    To the reports that Zoom was profiling your machine and storing all sorts of information unrelated to the Zoom call?
