In den vergangenen Monaten haben sich mehrere Hacker-Gruppen, darunter die Hacktivisten von "Killnet" und "NoName057", aber auch Ransomware-Gruppen zu neuen pro-russischen Kollektiven zusammengeschlossen, um den Kreml mit Cyberaktionen zu unterstützen. /2
In Hacker-Foren und #Telegram-Gruppen wird zu Angriffen auf Ziele in Europa, Nordamerika, die #NATO oder #EU aufgerufen, insbesondere auf kritische Infrastruktur, etwa Krankenhäuser oder Energieversorgung. Die Cyberakteure bezeichnen sich dabei als russische Patrioten. /3

"Since 2014, Ukraine was testing ground for cyber warfare and included multiple forms of attacks. Prominent was the 2015-2016 attack on power grids. This was among a small selection of attacks that disrupted physical systems in Western Ukraine,": @shakirov2036 #RussiaUkraineWar
"In Russia, there was no discussion of cyber security consequences if a war starts. Ukraine faced various attacks including viper attacks, and multiple government websites were defaced. This attack impacted provision of financial & govt services to public,": @shakirov2036

Vous avez raté l'actu du week-end ? Les sites miroirs de #LockBit 3.0 font l'objet d'une attaque #DDoS depuis quelques jours ⬇️
La raison ? La divulgation des données volées lors de la #cyberattaque conduite contre #Entrust, assure l'opérateur de la franchise #LockBit, logs de requêtes à l'appui ! 😲
Faudrait-il y voir une forme de #HackBack ?
Qu'a donc divulgué #LockBit, vendredi soir ? Des fichiers attribués à @Entrust_Corp, par l'attaquant, assortis d'un nombre, inégalé à ce jour, de 30 captures d'illustration, portant notamment sur ce qui ressemble à des données commerciales. Mais pas que...

Ce n'est guère une prise de position mais juste une mise en garde que je me permets.

Depuis hier 1e des informations majeures est la création de la #ITArmy pour soutenir l'#Ukraine
Le Ministre du digital ukrainien, Mykhailo Fedorov, appelle tous les volontaires à rejoindre ce groupe.

On pourrait penser que c'est une bonne idée mais non... J'ai reçu bcp de messages sur twitter auxquels je ne peux répondre hélas.
Des jeunes entrain d'apprendre le hacking ou voulant devenir hackers qui se sentent investis d'une mission veulent rejoindre les rangs de cette armée cyber.

Cyberangriff auf die Ukraine: Digitale Nadelstiche

"Webseiten ukrainischer Banken waren nicht erreichbar, aber das ist beinahe Kleinkram. Russland hat bereits gezeigt, zu welchen digitalen Attacken es fähig ist." zeit.de/digital/2022-0…
"Die Website des ukrainischen Verteidigungsministeriums war am Dienstag zwischenzeitlich nicht erreichbar. Zudem gab es technische Probleme bei zwei großen staatlichen Banken"
"Grund für die Ausfälle waren technische Überlastungen, die jemand bewusst erzeugt hatte. Die ukrainische Regierung sprach von einem "starken #DDoS-Angriff", auch die Streitkräfte des Landes seien betroffen."

Addressing availability problems for #dapps and their underlying #blockchains will be an important challenge for security architects in 2022. Right now we have a prime example of what a single dapp can do to a sidechain like @0xPolygon. What's going on? (1/6) Image
If you tried using #Polygon today, you will have noticed that the gas prices have spiked 10x from their usual level. (2/6) Image
Investigating further shows, that there is a single contract responsible for more than 50% of the gas fees right now! This must be a really important contract to warrant such a lot of transactions... Right? Right?! (3/6) Image

1) @hedera is going to be the🥇#cryptocurrency 💯. Disagree? Comment w/ 3rd party research to back your claims. Let’s open your 👀 & 🧠 to why $HBAR is the “best kept secret” in #Crypto & an undervalued, sleeping giant that the #blockchain community fears. Let’s dive in…🧐
2) INTRODUCTION - Hedera Hashgraph is going to be the “trust layer” of Web 3.0. It will be the foundation that everything will be built upon. It has solved the #blockchain trilemma, CO2 emissions, & the governance issues that plague other #cryptocurrencies.
3) INTENT- This post aims to educate and refute the FALSE FUD generated by @coinbureau & @IOHK_Charles that the community has incessantly regurgitated w/o understanding or DYOR.

#Ciberataque El Banco Bicentenario, en Venezuela, confirmó ésta noche que fue objeto de un ataque remoto a su plataforma informática con el objetivo de ingresar a la misma y alterar la data bancaria. El intento fue fallido aunque afectó la continuidad de los servicios desde ayer.
De acuerdo con la información compartida por el banco (registros de un sistema de protección de intrusos) fue un ataque DDoS, con miles de peticiones de acceso (de 13 mil a 15 mil) por cada atacante, con direcciones IP de Colombia en su mayoría. Eso causa un "atasco de tráfico".
El ataque de "denegación de servicio distribuida" o #DDoS (siglas en inglés) tuvo como objetivo los puertos 80 y 443 que son los que permiten la navegación web. Además de Colombia los ataques (según las direcciones IP) provenían de Angola, Brasil, Canadá, Chile, Ecuador y Perú.

Weil die #Leopoldina zur Zeit zu einem härteren #Lockdown rät (eine sogar höchstrangige Stellungnahme - siehe Bildschirmfotos!), wird von #Covidioten gerade eine #DDOS-Attacke auf die Leopolina geritten.
