Thanks Judith. You know, in these matters there is often some hype that makes it bigger than what it actually is, so I'd rather receive good, quality advice on this, rather than read the hyperbolic debates on the Internet.
Kindest regards,

Olivier

HI Olivier,

OK will write a note to the Tech team and ask them to do exactly that.  People are just coming back from Vacations so it is a bit slow.  I know I just got last night

Best,

Hello all,

discussions are heating up on the topic of Zoom both in NCSG mailing list, and on the EURALO discuss mailing list. Isn't this issue more urgent than waiting for a future TTF call, the date of which is, at present, not even set?
At least a call from the TTF to ICANN Tech Team to write a Blog of what their risk assessment is, with regards to this conferencing technology? In the meantime, conversations about this are springing up on several other mailing lists...
Kindest regards,

Olivier

Dear All,
+1 for JJS: set up a specifications sheet for a desirable conferencing tool, based on needs expressed by the multi-stakeholder community, and publish that as a tender. Offers received could then be reviewed not only by Staff, but in consultation with ACs and SOs.

Such needs include data privacy, technical stability and preferably open standards.

Best regards
Annette

Betreff: Re: [EURO-Discuss] Zoom Structural Vulnerability Discovered

First, a remark: for Adobe, Zoom or other tool providers, ICANN may not be the single largest client, but it is certainly a significant one owing to its nature (quasi-regulatory, multi-stakeholder, some parts geared to non-commercial users).

Then, a recommendation to Chairs of ACs and SOs: ICANN Board and CEO could be requested to set up a specifications sheet for a desirable conferencing tool, based on needs expressed by the multi-stakeholder community, and publish that as a tender. Offers received could then be reviewed not only by Staff, but in consultation with ACs and SOs.

This would get us closer to what we, collectively, consider as the appropriate tool for the numerous conference calls held throughout ICANN.

Jean-Jacques Subrenat.

This is assuredly right.  The change from Adobe to Zoom may, or may not, have been right for ICANN and for this group for any number of reasons ranging from cost, to security, to scalability and utility.  But let’s not romanticize Adobe.  They are not a terribly secure platform generically.  As James said, the Zoom response is poor – but we can’t hang that around the neck of ICANN org.

Just want to call out that Adobe has likely the worst reputation in the entire tech industry when it comes to security, I really would not hold them out as either prompt or without serious issues (I believe they still hold the record for number of CVSS 9+ vulns).
Zooms response is poor I agree, but on a data driven comparison it is a far more secure platform.

Subject: Re: Zoom Structural Vulnerability Discovered

That is true, but note that this security researcher notified Zoom of the exploit and they were in no rush to repair it. Look at the timeline in the Medium post. They only sought to fix it after the vulnerability drew media attention.

Adobe Connect was not perfect but it met our needs and the occasional security issues that arose were promptly fixed by Adobe and never as serious as this one!

Best wishes, Ayden

Speaking from a technical perspective, no software is perfect or bug-free. Its only a matter of time a loophole is found and exploited and eventually patched up. If you think Adobe Connect or ezTalks were/are free of these architectural issues, think again! That's the way we technical community do things.

Unfortunately, uninstalling the application does not rectify the situation, due to poor architecture (acknowledged by Zoom on their blog today). They are working on a fix, now that public scrutiny demands one. So disappointing that ICANN has put us in this terrible situation.

Hey - remember when ICANN switched everyone from Adobe over to Zoom as a way of enhancing information security and data privacy?

"A vulnerability in the Mac Zoom Client allows any malicious website to enable your camera without your permission... This vulnerability allows any website to forcibly join a user to a Zoom call, with their video camera activated, without the user's permission. On top of this, this vulnerability would have allowed any webpage to DOS (Denial of Service) a Mac by repeatedly joining a user to an invalid call. Additionally, if you’ve ever installed the Zoom client and then uninstalled it, you still have a localhost web server on your machine that will happily re-install the Zoom client for you, without requiring any user interaction on your behalf besides visiting a webpage. This re-install ‘feature’ continues to work to this day."
