@RealJamesWoods I liked you better when Peter baited you with candy, smh How misguided bigotry can be. We had all that and worse during 2016-2020. Dude "negotiated" peace deal with the Taliban.

About to workshop some malware analysis with containers @BSidesLV Signups for Kleared4, our disassociated Cyber Range is open for $1 lifetime registrations until Aug 10, 2200. Registration link: register.kleared4.com Wish me luck! #bsideslv @CompSecDirect

@CISOGovPR @pritsgov Gracias por tu excelente participación en el panel. Cuando la ley se firma, tuvimos tiempo para organizar el panel y si no fuera por panelistas como usted; el evento no hubiera sido exitoso. Estamos muy agradecidos por sus comentarios respecto a la ley 40 de 2024 @obsidis_org

Participé en el evento #BSidesPR para hablar sobre la nueva ley de ciberseguridad, además de los esfuerzos de política pública encaminados desde @pritsgov para la protección de la infraestructura crítica del Gobierno Puerto Rico contra ataques cibernéticos.

#bsidespr😎 Kleared4 cyber range registration is open. Link -> register.kleared4.com $1 one-time Lifetime for Early Adopters; get Kali VMs with containers, instances for malware analysis. Swing by the booth and get a super comfy shirt after registration.@obsidis_org

@runasand @RaicesCyberOrg @Google helped us get some of these for @BSidesPR We will give these out to folks and help them secure their accounts.

Google created the Advanced Protection Program to help high-risk individuals keep their accounts secure. The program is great (I’ve used it for years!), it’s just a shame the company rarely mentions it. glitchcat.xyz/p/googles-adva…
