Numerous media organizations are using headlines that two people from the Israeli Embassy were killed. The reality is this event had no advertisement of Israel, it was to celebrate Jewish Heritage. The goal was to kill Jews. @AJCGlobal @StopAntisemites @stoolpresidente
Is anyone else struggling with contractdition that @madebygoogle discontinued the Nest Protect before ensuring @FirstAlert was active. This means people can be without a smoke detector for months. Also the support claims to be human but is likely not. Transcript Available.
⚠️ We are collaborating with partners to respond to a recent compromise—discovered by independent security researchers—impacting Sisense. For more info, check out: cisa.gov/news-events/al…
How did anyone think this was a good idea?
There are news reports on a threat called tropical cyclone 16 could be targeting the Mid-Atlantic. Does @MsftSecIntel have any additional information that can be shared either here at #TLPClear or elsewhere. #WeatherNames wbaltv.com/amp/article/tr…

After the iOS 14 update I keep getting prompted to allow random apps to enumerate my network. Why does an online training app from @OReillyMedia need to scan my home network. No way this feature is abused right?
Honored to serve. We did it right. Defend Today, Secure Tomrorow. #Protect2020
This tweet reminded me of all the fun from @DerbyCon and how good a sport @HackingDave was about all the clown jokes. Pretty sure there is a “air gap” between #Pennywise and this customer so so am sure everything will be ok. Hope everyone out their is taking care of themselves.

Whenever someone not in #cybersecurity says the network is secret but connected to the internet run away from their recommendation. Untested same day voting registration is somewhere between a bad and a awful idea. #protect2020 #elections #sighbersecurity washingtonpost.com/local/md-polit…

Had to fix my parents email after the username and logon were guessed. Horrified to learn that @CoxComm does not even have the option for #MFA / two factor authentication. How many millions of people are at risk to #PII theft when their email is hacked ? #CyberSecurity #Hacked
Winding down my @DerbyCon IX experience. Don't cry because it's over, smile because it happened: @BanjoCrashland @iagox86 @HackingDave @chaumurky @cantcomputer @irongeek_adc @brysonbort @jorgeorchilles @at1as @SW_Samii @Carlos_Perez @wimremes @lelandneely @that_guy_ego
If you’re at #derbycon and looking for a job check out this tweet. This is a great way to cut out a lot of the pain of applying to Gov jobs. You also get to help protect the country.

I think @DerbyCon & @HackingDave will find this interesting.
