Recently, I had fallen sick. A serious cold forced me to spend my days on the couch. We like to imagine sick days as a chance to take a break on a comfy sofa with a nice cup of tea and lots of time to read and maybe even a beloved movie interrupted only by the occasional need to clear our throats. In reality, my eyes were burning, my lungs wheezing and may brain obviously restricting its activity to mere life support. So what harm could there have been in picking up the remote and watching a much-lauded series in one sitting?
Until now, the update policy of many Android cellphone manufacturers resembled the nursing behavior of a cuckoo: they took to their heels. This annoyance has been tolerated by buyers for several years, maybe many didn't even realize the importance of regular updates. Only owning a Google-backed device like Nexus or Pixel meant you were on the safe side. Super cheap phones were sometimes even cut off from updates the moment they were sold. This grieved not only users but also Google - and it may finally be about to change with Android One!
You can't escape them. They're in the news, on entertainment programs or show up in Internet ads. Cryptocurrencies are ubiquitous. But how do they work and how can a single individual, that might not even exist, invent a new currency along with the technical foundation? Though there are now quite a number of cryptocurrencies available, I'll focus on the darling of the digital currency movement: Bitcoin.
Seldom does the media paint a more distorted picture than when it comes to hacking. It goes something like this: a man wearing a balaclava sits in a dark room typing away at his computer. Green cryptic characters fill up his screen until he reaches his murky goal! So far, so unrealistic. That there's more to the hacker community that once featured prominent members like Apple founders Steve Wozniak and Steve Jobs and that many security issues became public thanks to hacking is a story that is rarely told. And the many positively motivated members are also swept under the rug all too frequently. Reason enough to take a closer look at hackers.
As a computer scientist, I deal with security vulnerabilities on a daily basis since the perfect operating system has just not been found yet - but this time I almost spilled my tea when I read the news. This issue was different and it affected the core of all computer calculations: the processor itself. And it wasn't just any processor that was vulnerable but practically all of them whether they were built into PCs, cellphones or servers all over the world. This time, the remedy wasn't a simple browser patch. Every operating system had become unsafe taking the wind right out of the sails of Apple users who like to point their fingers at the supposedly inferior security of Windows systems. They were all in danger. Even those who owned none of the CPUs listed couldn't just sit back and relax because the servers that host and process all of our data could also be affected. Read on to learn what happened and how manufacturers are dealing with the dire situation.
