A few months ago (January 2018), the media reported breaking news of alleged security failures for Intel and ARM processors. In order to understand these “weaknesses”, and before briefly describing the nature of these “security holes”, we need to list some of the common characteristics shared by modern processors.
The Meltdown and Spectre vulnerabilities were discovered last year, but only disclosed recently to the public. Both vulnerabilities are of the same family. They fundamentally affect certain CPU designs with around 20-years’ worth of processors and certain upcoming designs cannot be classified totally secure.
The first and so far the only time I was personally involved, (or to be more precise my son who at that time was eleven years old), in a cyber-attack by ransomware was in 2012. The computer of my son was apparently blocked by the Federal Criminal Police Office due to some illegal actions, such as sending spam mails and even worse. At least that’s what appeared on the screen in poor German. Strangely enough a fee of 100 Euros would unblock the computer.

Round about one million DSL routers, mainly devices from Germany’s biggest telecommunications carrier, fell victim to hacker attacks. (more…)
Since September, several cyber-attacks have targeted a series of entities present in the network (including DNS Internet service providers, numerous webs residing in Liberia and the personal page of an expert in online security). (more…)
