Parce que le #covid19 et que le #MasquesObligatoires ne permet le débat serein sur la #ventilation des locaux #QAI, je me lance dans un #thread sur cette norme complexe. Pardonnez-moi d'avance si quelques imprécisions s'y glissent ^^ ⤵️
Je me base sur le dernier avis du @HCSP qui déclare dans les avis du 24 avril et du 30 juillet que la #ventilation des locaux doit être renforcée en #EHPAD, #hopitaux et #ERP (ex : #écoles) hcsp.fr/Explore.cgi/Te…
D'ailleurs, page 3, il recommandait un certain nombre de mesures sur une #ventilation systématique des locaux, la vérification/remplacement des filtres. Il prenne l'exemple des bateaux de croisières et des restaurants avec une contamination accrue au #covid19

Die #IT-Umgebung des indischen #AKW's Kudankulam wurde nicht nur gehackt, sondern als Command and Control Server benutzt.

Hoffentlich war die #OT nicht auch öffentlich am Netz!

#KRITIS Sektor #Energie #nuclear #nuclearsafety #Resilienz #Cyber #Security

Zur Unterscheidung:

IT sind Informationstechnische Systeme (#PC #Laptop #Windows #Office, #Buchhaltung...)

OT sind Operative Systeme (#ICS #SCADA #SPS #HMI #PLC #Steuertechnik...)
Angemessener Stand der Technik #SdT wie in #KRITIS gefordert wurde offenbar im #AKW nicht eingehalten.

Strikte #Trennung zwischen #OT-Steuersystemen und #IT ist eine wesentliche #Sicherheitsmaßnahme!

"As Twitter is blocked in PRC, many of these accounts accessed Twitter using VPNs. However, some accounts accessed Twitter from specific unblocked IP addresses originating in mainland China."
Twitter followed up this takedown with another major announcement: Twitter will no longer accept advertising from state-controlled (either financially or editorially) news media. Presumably, this should apply to RT, Sputnik, Xinhua, etc.

When is someone's POC newsworthy - especially for #ICS? We've had IRONGATE, we've had "Clear Energy"... both made headlines, neither were "in the wild" attacks, and one was more or less notional - but then there's this set of things: pastebin.com/riBhHwUE
Essentially, someone appears to be developing a ICS proof of concept over time as a double-extension EXE that displays a PDF while running some Python in the background. Initially it started pretty simple.
But over several months of apparent development, things got a bit more robust:
