Unquestionably the funniest POC for an exploit I have ever seen in my life
https://github.com/tinkersec/cve-2020-1350
That's the news, folks. Hope everyone is well.
Big news this week was the F5 zero day, of course, but on the application side you should review the code for the exploit, which is public. I am not gonna link it here but y'all can google. DO NOT run this on your corporate machines, use your test box and a VM, and just look. Here is a link to the CVE:

We are back on the encryption discussion. Let me make my own, personal, not endorsed by anyone, position very clear. Anyone - ANYONE - can encrypt anything with two coins, a pencil, and a piece of paper. These laws do NOTHING. Nothing at all. Please tell everyone. If you have questions, please ask. If I don't know the answer, I know people who do.

The fantastic Google Project Zero wrote a neat instrumentation library that is ACTUALLY lightweight for Windows 32 and 64.

Scott Goette12:27 PM
dev and qa are on your production network, right?
or does everyone practice network segmentation and not poke holes through firewalls?
Kris Wall12:28 PM
I've found plenty of half baked and abandoned apps with access to prod and internal DBs
Bob Caruso12:29 PM
Pivot-through is usually the biggest threat. spot on, @Kris Wall
Scott Goette12:35 PM
ooohh - like this. Different Security engagements should be appropriately timed for accuracy
You12:43 PM
Deployment too. Sometimes you have out of date third party components, and ops has to get involved.
Chris Brew12:47 PM
All of this makes sense in a big tech company context, except that it is not directly financial. Engineering resources are still limited, and over-committed, and there is still an aggressive timeline.
Kris Wall12:48 PM
I take this into consideration when sending my reports. Each remediation issue turns into an action item and each item has to be well-defined for the dev team.
Brandon Lewis12:49 PM
To add on to Chris' comment, it's still a lot of $$$ at the end of the day - rewrites are never cheap especially for large applications (refer back to estimates).
Warner Moore12:49 PM
Re-writes are almost never the answer.
Andrew Fitzgerald12:52 PM
+1 for "don't touch my tech debt"
Bob Caruso12:52 PM
I can see Bill's arms waving, but no sound
Chris Brew12:52 PM
A Facebook specific is that privacy is an extremely big stick to wield. No one can or should say no to a security person who has a justified privacy concern, because it is officially a non-negotiable priority. But dev teams still face all the prioritization issues you raise.
Warner Moore12:53 PM
Depends on the allocation. I typically like 20% for tech debt, security, etc.
If you'd prefer it not to be touched, it can be a smaller part of the pie. ;)
Kris Wall12:53 PM
Devs get upset if you can't define the problem. :)
Doron Samuel12:55 PM
I was about to say that point in the chat box :)
Bob Caruso12:58 PM
Scenarios are the most convincing when you can use the developer's own code (via pen test).
Kevin W. Wall1:02 PM
A great example of letting the perfect becoming the enemy of the good.
Jennifer Middleton1:03 PM
+1 ^
Bob Caruso1:04 PM
Also, developers are trained to not touch working code and are often measured/rewarded by shipping new features (tied to revenue) and not by remediations or weaknesses closed. SOLUTION: Put a $ value on remediations, and/or turn cybersecurity controls into product features that are advertised to customers so that they get pulled through the whole dev pipeline.
Kevin W. Wall1:07 PM
Great prezo. g2g to work mtg. Stay safe everyone.
Warner Moore1:08 PM
Security features in products is looking at it from a value creation perspective and not necessarily an operations perspective. A robust security program for a modern tech organization requires both security features in the products and security capabilities within the organization. Often, that distinction is missed which means the security program is lacking in an area.
Kris Wall1:08 PM
We need to be nicer?
Sure. I guess!
You1:09 PM
Maaaaaaaaaan, I was just working on being grouchier like Kevin
Brandon Lewis1:09 PM
As a dev (looking to transition into security), sounds like there's a big lack of security champions on the dev side - someone who can be a realistic bridge of communication/reason so it doesn't feel so "security versus app teams".

Kris Wall1:11 PM
@jamie If we need to get more forceful with dev teams and their governance, let's say there's continual push back, do you have any suggestions for being effective and not burning bridges?
Robert Ravenscroft1:11 PM
As always, great job Jamie!
Warner Moore1:12 PM

Brandon Lewis1:12 PM
Are the issues discussed here a really common experience for security folks trying to engage app teams?
Warner Moore1:12 PM
;)
Kris Wall1:13 PM
Push back from dev teams is quite common.
Kris Wall1:17 PM
Scans are OK for finding low hanging fruit, but not a replacement for security assessments.

agreed, a scan is just the start. It should result in a systemic improvement
