Media is going crazy about #Meltdown and #Spectre. Should you panic, too?
Here are some of my thoughts on that recent security desaster:
- Don’t worry. Your systems have been damaged for twenty years, probably. A hardware vendor (probably more, maybe all of them) sold buggy chips, and they have been broken since 1995 or so.
- It became known during the summer of 2017. At least, but surely not only since then a realistic chance of exploits was around, which became imminent some weeks ago and led Google/Intel to withdrawing from deadline and going public.
- Yes, your systems are most likely affected. If you were not asked recently (i.e. since last Wednesday) to upgrade your kernel, then you have a problem. You are not affected if you are running hardware older than 1995 or some ARM stuff. Your kernel should now be 4.14.11 or newer – or contain backported code if it is an older version.
- The patches deployed by all major OS vendors last week will make your systems significantly slower. However they will fix most of the problems, but not the ones that are so deep into hardware that no software can fix. Yes there are. But if you are only gaming, sending mails, writing office documents and browsing the web, you won’t even notice. However, if you are a database admin or running DNS servers or Enterprise Clouds – anything with many “context switches” between userland and kernel space, then you’re likely to suffer from performance loss..
- The whole story may even become an #intelgate, because rumors have it that Intel had prior knowledge and some strange things going on with testing. Rumors, nothing more, except for a CEO selling most of his Intel stock in November and a flaw that makes systems 30-50% faster, but for what a price?
I like it when your gut feeling proves to be right. Hackernews just published this https://thehackernews.com/2018/01/western-digital-mycloud.html:
“Security researchers have discovered several severe vulnerabilities and a secret hard-coded backdoor in Western Digital’s My Cloud NAS devices that could allow remote attackers to gain unrestricted root access to the device...”
I have one of these devices, and after a first glance I deactivated the software as fast as I could – obviously my intuition was right.
What people feel and what is actually true – that’s often not quite the same. Expecially when it comes to security, merely feeling safe sometimes seems to be more important than reality. As the blog “Erich sieht” shows that is true cycling as well. The British National Health Service NHS puts it in a very short sentence:
“Official figures taken from the NTS suggest that the general risk of injury from cycling in the UK is just 1 injury per 19,230 hours of cycling.”
“Erich sieht” does the math for you: A typical bycicle courier would need to work for ten years, 40 hours per week to suffer his first injury – statistically.
Having a fine debate – it’s just the best thing to do on a wednesday, right?!
In 2013 I was invited to “Twittwoch” (literally a combination of “twitter” and “Mittwoch”, meaning wednesday in German) talking about data security in Munich. On the panel such interesting fellas as Jerzy Montag, then member of German parliament, Daniel Duda, an expert on cyber security, Tanja Gabler from Internet World Business, Stefan Gröner and Dr. Guido Brinkel (1&1 Internet AG, Expert Government Relations).
Watch to the interesting discussion presented by our host the amazing blogger Thomas Pfeiffer.
(In German only.)
It’s abut freedom of speech, so the stakes are rather high.
It may sound a little overwhelming, but the tide is high in the controversy about the newest data (security) and privacy laws in Germany and Twitter. Because of the new legislation, mainly done by Heiko Maas (social democrats), that was supposed to stop digital harrasment and racism, kicked fully in: but not in the way it seemed designed for. The satirical magazine “Titanic” got shut down on Twitter (by Twitter) for its parody on altright politician Beatrix von Storch.
