#DFIR Manager, but first of all, #IncidentResponder. Tweets are my own! I'm everyday trying to learn coding to do more than PRINT HELLO WORLD.

WANTED❗️ @blackhat!

@Bitwarden In the meantime, probably three weeks ago I just submitted my company partnership proposal through your web site, but I never had a response, not even confirming or denying.

[Jefferson Macedo @jsmacedo]

Hey, @Bitwarden, why does it take so so long to get a response from your Sales/MSP Partnership team? God, how will I trust to have the partnership with you if only to respond a message and confirm or deny the partnership proposal, you take so long? This is crazy. I'm from a MSP.

[Jefferson Macedo @jsmacedo]

@Bitwarden Not from this morning. I exchanged some messages with your Channel Manager in July, 11, and I asked how to move ahead with the partnership, but I got no response. In the last Sunday, I asked again in the same thread, but I still have no response.

@gpresman @chadtilbury @antoniosanzalc @SwiftForensics @CyberCX has any type of geolocation blocking (at least if you are in Brazil 🙃). If you use a VPN to get an Australian IP it works fine.

@Avell_Notebooks conseguem resolver o problema: https://t.co/7yQmCXN5NJ? Está difícil conviver com um laptop caríssimo danificado por conta da baixa qualidade da dobradiça que vocês utilizam no projeto do c62mob (e de muitos outros de acordo com feedbacks no @ReclameAQUI, né?)

@bhttparitosh @cyb3rops Any - Any, may be helpful as well! At least no one will complain about Internet Access, not even the TA

Se a sua criança está correndo "perigos mortais" e tendo sua vida "devastada" por usar a internet, a culpa é exclusivamente sua que não está cuidando da sua criança direito...

@VoeGOLoficial, por Deus, vocês precisam fazer o botão “opt out” dos e-mail marketing funcionar. Vocês mandam 2 ou 3 e-mail marketing por dia! Isso é chato! Já tive problemas no passado, removeram meu e-mail e só porque voltei a viajar pela Gol, voltou a enxurrada de e-mails…

For a long time, I thought the only way to run a successful pentesting practice was to have access to expensive tooling and software.

This is completely untrue. Here's what we use internally at @risk3sixty to run pentesting engagements (for little to no cost whatsoever):🧵

Just sharing a malicious URL I got from a quite fresh #SpearPhishing campaign attempt to gather O365 users credentials. Thank you! You're welcome! :)

We have observed a China-based ransomware operator that we’re tracking as DEV-0401 exploiting the CVE-2021-44228 vulnerability in Log4j 2 (aka #log4shell) targeting internet-facing systems running VMWare Horizon. https://t.co/6GOdRwRTjk

[SANS.edu Internet Storm Center @sans_isc]

#log4shell FAQs/Misconceptions:
- This is not related to the Apache web server. log4j is maintained by the Apache foundation (they do a lot of neat things)
- No, 4 Billion devices running on Java are not vulnerable. Software using #log4j (= many enterprise apps and Minecraft!)

I created a #CyberChef recipe to ease the extraction of URLs from the word document (.doc & .docm) which download #Emotet. It is not completely foolproof, but it worked 99% of the time for me.
