Google’s AI can create better machine-learning code than the researchers who made it

Posted by jpluimers on 2017/10/17

[WayBack] Google’s AI can create better machine-learning code than the researchers who made it:

Google’s AutoML project has yielded significant advances in the ability for machine-learning systems to replicate and improve AI code.

RSA keys by Infineon chips or libraries can be cracked fast; Severe flaw in WPA2 protocol leaves Wi-Fi traffic open to eavesdropping…

Posted by jpluimers on 2017/10/16

All of our house is wired by ethernet for a reason…

WPA2 Flawed. Once again, it turns out that designing something properly secure is really, really, REALLY hard.

[WayBack] Severe flaw in WPA2 protocol leaves Wi-Fi traffic open to eavesdropping https://arstechnica.com/… – Lars Fosdal – Google+

[Archive.is] If fixes exist, third party firmware will have it in days. Most OEMs, never. I do worry a lot about unfixable flaws in the wifi standards… – Kristian Köhntopp – Google+:

Dave reminds us that there is a reason why people mod the firmware of their Wifi routers, and that reason is actually now more critical than ever.

Via [WayBack] https://www.krackattacks.com/ has a FAQ. Some interesting questions from there:… – Kristian Köhntopp – Google+:

[WayBackKRACK Attacks: Breaking WPA2 : This website presents the Key Reinstallation Attack (KRACK). It breaks the WPA2 protocol by forcing nonce reuse in encryption algorithms used by Wi-Fi.

 

Since we’re talking security, watch your RSA as it is way worse than the WPA2 one: [Archive.is]

We heard you liked the 10 WPA2 CVE’s, so »A 2nd major crypto vulnerability being disclosed… – Kristian Köhntopp – Google+ quoting

[WayBack] Dan Goodin‏ @dangoodin001: 2nd major crypto vulnerability being disclosed Monday involves millions of 1024- and 2048-bit RSA keys that are practically factorizable.

[WayBackROCA: Vulnerable RSA generation (CVE-2017-15361) [CRoCS wiki]

The time complexity and cost for the selected key lengths (Intel E5-2650 v3@3GHz Q2/2014):

  • 512 bit RSA keys – 2 CPU hours (the cost of $0.06);
  • 1024 bit RSA keys – 97 CPU days (the cost of $40-$80);
  • 2048 bit RSA keys – 140.8 CPU years, (the cost of $20,000 – $40,000).

[WayBack] New vulnerabilities found in RSA 1024 and 2048 bit keys. Estimated cost of cracking based on access to the Public key only: 1024 bit: $40 2048 bit: $20k… – Lars Fosdal – Google+

Jan Wildeboer did a nice explanation in laymen terms of both security issues published today:

Posted by jpluimers on 2017/10/13

We all know the feeling of insomnia. Your body wants to sleep but your mind is still awake and active. So how can we steady up our mind. Napflix is a video platform where you can find the most silent and sleepy content selection to relax your brain and easily fall asleep. Taking siesta wherever and whenever you like.
