KrackAttacks: What you need to know – Safe and Savvy Blog by F-Secure | #CyberSecurity #Awareness #VPN #Router | ICT Security-Sécurité PC et Internet | Scoop.it
Here's what you need to know about KrackAttacks, and what you can do to protect yourself.

 

And there’s the silver lining.

We’ve actually been living with the risks created by insecure Wi-Fi connections for many years, and users can protect themselves by taking some basic security precautions. Here’s the best ways to stay safe from KrackAttacks and other threats targeting people through their Wi-Fi connections:

 

Use a VPN

A VPN (virtual private network), such as F-Secure Freedome encrypts your data while it’s in transit. This is a great way to secure your information when using Wi-Fi, and should be considered essential when using a publicly accessible Wi-Fi network.

 

Update your devices

Attacking routers is a means to an end for attackers. What they’re really after are your devices. They want to steal your credit card info, passwords, and other data. And that’s what the KrackAttacks are actually doing. Updating your devices’ software and operating systems is sound security advice, so use this as a reminder to make sure your desktops, laptops, phone, and tablets are all updated.

 

Update your routers

Routers have a long history of security problems. They’re often poorly supported by device vendors (and in some cases not at all). You should check your router’s settings to see if there’s a firmware update available, or possibly the website of your router’s manufacturer or vendor. If you’re not getting security updates for your router, consider getting one built to be secure.

3 million strong RAMNIT botnet taken down | CyberCrime | CyberSecurity

3 million strong RAMNIT botnet taken down
Posted on 25.02.2015
The National Crime Agency’s National Cyber Crime Unit (NCCU) worked with law enforcement colleagues in the Netherlands, Italy and Germany, co-ordinated through Europol’s European Cybercrime Centre (EC3), to shut down command and control servers used by the RAMNIT botnet.

RAMNIT spread malware via seemingly trustworthy links sent out on phishing emails or social networking websites. If users running Windows clicked on the links, the malware would be installed, infecting the computer. Infected computers would then be under the control of criminals, enabling them to access personal or banking information, steal passwords and disable antivirus protection.

Investigators believe that RAMNIT may have infected over three million computers worldwide, with around 33,000 of those being in the UK. It has so far largely been used to attempt to take money from bank accounts. Analysis is now taking place on the servers and an investigation is ongoing.

Désormais un simple PC suffit pour faire tomber les plus gros sites | #CyberSecurity #DDos

Désormais un simple PC suffit pour faire tomber les plus gros sites | #CyberSecurity #DDos | ICT Security-Sécurité PC et Internet | Scoop.it
Pour faire tomber des sites avec une attaque de type « Déni de service » (DDoS), plus besoin d’utiliser un grand nombre d’ordinateurs ou de louer les services d'un botnet, un seul PC peut suffire !
Les chercheurs danois de TDC ont révélé une nouvelle technique d’attaque qu’ils ont baptisés BlackNurse. Sa particularité est qu’elle ne nécessite qu’un seul ordinateur et une liaison internet de bonne qualité (au moins 15 à 18 Mbit/s). En comparaison, les dernières attaques DDoS contre le les fournisseurs Dyn et OVH ont nécessité des débits de l’ordre de 1 Tbit/s.

Comment arrive-t-elle à être aussi efficace en nécessitant si peu de puissance de feu ? Au lieu d’envoyer une grande quantité de trafic sur les serveurs, BlackNurse envoie des paquets de données spécifiques (Internet Control Message Protocol) qui sont utilisés par les appareils réseau pour la transmission de messages d’erreur. Ces paquets vont surcharger les processeurs des pare-feu conçus par des constructeurs connus tels que Cisco ou Palo Alto Networks.
