#iLeakage: Browser-based Timerless Speculative Execution Attacks on #Apple Devices
Source: https://ileakage.com
We present iLeakage, a transient execution side channel targeting the #Safari #web #browser present on Macs, iPads and iPhones. iLeakage shows that the #Spectre #attack is still relevant and exploitable, even after nearly 6 years of effort to mitigate it since its discovery.

Une #souris #optique plus puissante que les #ordinateurs des années 80 - #DeusExSilicium
https://www.youtube.com/watch?v=Tak8Pz4GSn8
On vit une époque étonnante dans laquelle il existe une souris optique dont la puissance de traitement dépasse celle des PC des années 80 ou de l'ordinateur de la NASA qui a permis à Apollo 11 de se poser sur la lune. Voici la vidéo qui analyse et décortique intégralement cette souris Logitech G502 Lightspeed.

The Nameless Thing of 50 Berkeley Square
50 Berkeley Square, London, England was for many years renowned for being visited by some sort of creature and terrifying any guests, some fatally, who dared spend the night there in a specific room. Descriptions of the creature vary but the common features seem to be some sort of Octopus type creature in nature.
But what’s the most rational explanation for this incident? By rational we mean, can the explanation be proved to be a plausible one?
Just look at the list below of explanations. Remember, whichever one(s) you pick as being likely ask yourself if you can prove them to be possible:
1 - A real monster.
2 - A spectre or ghost.
3 - Some sort of a demon or creature from mythology.
4 - A real octopus type creature that was able to find its way up from the sewers to that room.
5 - A lie or fabrication to cover something up.
6 - A lie or fabrication to benefit someone in some way.
The article below goes onto look at some of the possible explanations for the incident

Computer scientists discover new vulnerability affecting computers globally
A team of computer science researchers has uncovered a line of attack that breaks all Spectre defenses, meaning that billions of computers and other devices across the globe are just as vulnerable today as they were when Spectre was first announced. ...
...
Since Spectre was discovered, the world's most talented computer scientists from industry and academia have worked on software patches and hardware defenses, confident they've been able to protect the most vulnerable points in the speculative execution process without slowing down computing speeds too much.
They will have to go back to the drawing board.
