Holy crap this is awful.
Imagine a tech conference having no CFP, as they reach out to speakers directly. They successfully attract some of the most heavy hitter men speakers in tech, and 3 women speakers. Now imagine my surprise that 2 of those women are FAKE profiles. They do not exist. Nada.
@chetdorn Too afraid to ask them out of concern they’ll point at me.
Love it.
And then all I had to do was click a purchase button, authorize Apple Pay, and now I’m “verified” too? This really doesn’t make sense. My voice doesn’t carry the same weight as there’s does (or did).
I think back over the years about the people I’ve followed who had huge follower counts and real influence and a meaningful voice. When they became Twitter verified it meant something to them and their followers.
Nice to see a company take full ownership for an embarrassing snafu. And unlike the infamous @HBOMaxHelp email screw up of the summer of 2021, it’s nice to see @Malwarebytes isn’t bothering to offer the responsible intern with any help. Long live interns… and snark 🤣
@mediaphyter Thought I was the only one.
Serious FOMO about @BlueTeamCon, especially as I’ll be on a tight schedule moving my son into @DePaulU just 30 short minutes away.
@gabsmashh Started off as a contractor in the defense industry, cutting my teeth on the Orange Book and Common Criteria. Then 1st line mgr. Then a referral to a leadership role in FinServ. Grew that org over 15 years before making CISO. That referral was critical.
Outstanding talk and a great summit. Lots of great information being shared to help improve the resiliency of the industry.
WATCH: Cybersecurity and Infrastructure Security Agency Director Jen Easterly (@CISAJen) on chemical infrastructure security at the agency’s summit c-span.org/video/?522468-…
Okay, I just read JDs "scientific" paper. TL;DR "CitizenLab has not shared all evidence publicly, so their research is fake." According to JD, one needs to be at least a PhD student to be able to "asses" his research. So here we go.
Don’t wait to read about it in the news or from colleagues, get CISA’s updates to the Know Vulnerabilities Catalog sent directly to your inbox!

@securitybrew Wait! What is this doxie race you refer to and how have I not ever known about this?
Interesting development on the march towards a modernized government operation.
@CircuitSwan @CISAJen would definitely top my list.
@GossiTheDog Agreed! And equally bad is the option to place a phone call. After 4-5 of those it becomes tempting to either silence the phone number or, for those that don’t know better, to just click that pound key to “approve”.
Some pretty useful and timely content on how to secure and protect yourself on Twitter from their safety account. Spread the word - quote tweet them directly.
@SushiDude What do you get at 40 years?
@SushiDude I’ve been gone from there 22 years :-) Time is relative.
