I'm limiting twitter's access to my attention of late. Email will be seen quicker than DMs: my handle (w/o underscores) at cert dot org.

Based on suggestions from
@RonnyTNL and@__adh__ I've updated https://gist.github.com/wdormann/0a6ee811627ba5610c945f4af4dd987f … No longer requires dumpbin.exe or listdlls.exe (if Python pefile and psutil are available). Also exports the findings as a CSV. Any reported app is a good candidate for EMET or WDEG force ASLR!pic.twitter.com/oTSzeElm2d

Our understanding of vulnerabilities and their impact on a *population* or systems is super immature, especially when it comes to operational technology that is 1) mission critical but also then 2) slow to change. (1/2)https://twitter.com/kennwhite/status/1217838723343273984 …

The cat's pretty much out of the bag on how to exploit this. Expect widespread exploitation attempts for CVE-2019-19781 at this point. Despite being almost a month old, there is NO PATCH from
@citrix at this point. Only a (very important) mitigation. https://www.kb.cert.org/vuls/id/619785/ https://twitter.com/HackingDave/status/1215684853724741634 …pic.twitter.com/mYyokzy2pq

At Google Project Zero, the team spends a *lot* of time discussing and evaluating vulnerability disclosure policies and their consequences. It's a complex and controversial topic! Here's P0's policy changes for 2020 (with our rationale for the changes): https://googleprojectzero.blogspot.com/2020/01/policy-and-disclosure-2020-edition.html …

Ah yes, Travelex and the curse of unpatched critical Pulse VPN vulns leading to a major incident. People ask "why is patching so hard for orgs?" I work for a large UK hospitality org. We run Pulse Secure VPN. It took ages to sort patching out & I'll explain why, so thread..

This came in really handy once when I had to mask out all but one /24 in a /8 before the mandatory backoff timer on our scheduled outage triggered. Somewhere I have the sheet of paper where I did this on the fly while a colleague was on hold with the firewall vendor tech support.

There is a real divide which I'm just beginning to notice between people who try to do the thing that has the most chance of a good result, and people who want to maximize their chances of being able to say I told you so.
