Why do we get such stupid ads? Because it’s only a numbers’ game…

Newco Shift : Dear Advertising Industry: Please Do Better. You’re Killing the Open Web. … :

Let’s apply that reality to our robe example. Let’s say the robe costs $60, and yields a $20 profit for our e-commerce advertiser, not including marketing costs. That means that same advertiser is can spend upwards of $19.99 per unit on advertising (more, if a robe purchaser turns out to be a “big basket” e-commerce spender).  So what does our advertiser do? Well, they set a retargeting campaign aimed anyone who ever visited our erstwhile robe’s page.  With CPMs averaging around a buck, that robe’s going to follow nearly 20,000 folks around the internet, hoping that just one  of them converts.

The City of Atlanta, Georgia has been hacked.

Reality update: Hackers Are Holding The City of Atlanta Hostage … :
“This is much bigger than a ransomware attack, this really is an attack on our government,” Atlanta Mayor Keisha Lance Bottoms said at a news conference, Reuters reports. “We are dealing with a (cyber) hostage situation.”

(…)

Experts have warned that cybersecurity is likely the next great security threat for governments and companies around the world, and that most systems are simply not prepared. Indeed, Atlanta isn’t the first U.S city to be hit by ransomware — the Colorado Department of Transportation has already been hit twice in 2018. However, the Atlanta attack seems to the most thorough, city-wide cybersecurity breach yet. And though some companies have ramped up security following attacks, as Atlanta plans to do, it seems that most cities aren’t adapting their security before an attack happens.

(…)

It’s not yet clear at what point Atlanta will give in and pay the ransom to get its data back. But as more cities rely on digital processes, the dangers to both citizen privacy and security are going to multiply. Imagine a hack that takes out not just a city’s computer systems, but also its electrical power, plumbing, and even control of your own car.

Microsoft is now censoring its users, scanning all content for “inappropriate” stuff

Reality update: Microsoft to ban ‘offensive language’ from Skype, Xbox, Office | CSO Online … I doubt this is fine with German data protection laws:

Better watch out if you are playing Xbox, get ticked, and cuss. Microsoft might ban you for the “offensive language.” If they do, then say bye-bye to your Xbox Gold Membership and any Microsoft account balances.

Darknet demystified – The Limits of Anonymity.

The error is on OSI Layer 8, and even the best technology won’t help you if you use it wrong. In this article about the Darknet (Heise I’X, in German) I demystify many “given” assumptions. No NSA, no police, nobody needs to crack your cryptography if you do the same silly mistakes like so many others before you.

Darknet demystified

Update: Early in February I was interviewed by Radio Berlin Brandenburg about the my opinion on the darknet.

Wechselwahn – why it does not make sense to enforce recurrent password changes.

In this article for Heise I’X (in German) I present statistical and empirical evidence why it usually is a bad idea to force your users to change their password regularly. In fact, you’ll maybe push users to use patterns for their passwords that are cracked much easier than their password. What is a good password, and why you should only change it when you have reason for doubt. “You will need good reason to push your users into regularly changing their passwords – and only in few cases or insecure environments this may make sense at all…”
