Former Yahoo CEO Marissa Mayer Apologizes for Data Breach, Blames Russian Agents

Former Yahoo CEO Marissa Mayer apologized today at the Senate Commerce, Science and Transportation hearing regarding massive data breaches at the internet company, blaming Russian agents. more

The Darkening Web: Is there Light at the end of the Tunnel?

In his book "The Darkening Web: The War for Cyberspace" (Penguin Books, New York 2017), Alexander Klimburg, an Austrian-American academic, gives "Internet Dreamers" a "Wake Up Call". He tells us the background-story why people start to be "anxious about the future of the Internet", as the recent ISOC Global Internet Report "Paths to Our Digital Future" has recognized. Klimburg refers to Alphabets CEO Erich Schmidt, who once said that "the Internet is the first thing that humanity has built that humanity does not understand". more

A European Perspective on the Equifax Hack: Encouraging Data Security Through Regulation

The Equifax hack is understood to have compromised the personal data of over 140 million individuals. Although recent hacks of other businesses have affected more individuals, the personal data held by Equifax is significantly more sensitive than the data compromised in other hacks and includes Social Security numbers, birth dates, current and previous addresses and driver licence details... (Co-authored by Peter Davis and Brendan Nixon.) more

Preliminary Thoughts on the Equifax Hack

As you've undoubtedly heard, the Equifax credit reporting agency was hit by a major attack, exposing the personal data of 143 million Americans and many more people in other countries. There's been a lot of discussion of liability; as of a few days ago, at least 25 lawsuits had been filed, with the state of Massachusetts preparing its own suit. It's certainly too soon to draw any firm conclusions... but there are a number of interesting things we can glean from Equifax's latest statement. more

The IoT Needs a Paradigm Shift from Security to Safety of Connected Devices

Building IoT ventures from scratch by prototyping hardware devices and their backend systems as well as working for a large company that tries to sell IoT devices itself, we learned a lot about the pitfalls and problems concerning security in the IoT. Nearly every connected device out there proved to be vulnerable to attacks. Researchers showed that it's possible to remotely take control over autonomous vehicles, implanted medical devices were manipulated, voting machines compromised and of course all sorts of other "smart" devices... more

Major Flaw Found in WannaCry Raises Questions on Whether it was Really a Ransomware

An extensive analysis of WannaCry seems to indicate attackers would be unable to determine which users have paid the ransom and they cannot decrypt on a per-user basis. more

Security Costs Money. So - Who Pays?

Computer security costs money. It costs more to develop secure software, and there's an ongoing maintenance cost to patch the remaining holes. Spending more time and money up front will likely result in lesser maintenance costs going forward, but too few companies do that. Besides, even very secure operating systems like Windows 10 and iOS have had security problems and hence require patching. (I just installed iOS 10.3.2 on my phone. It fixed about two dozen security holes.) more

IoT Devices Will Never Be Secure - Enter the Programmable Networks

Harvard Business Review just ran an interesting article on the information security aspects of Internet of Things (IoT). Based on the storyline, the smart city initiatives are doomed to fail unless the security of the IoT devices and the systems will be improved. While security of the digital society is obviously a key concern, I am not entirely convinced that relying on the security of individual devices and systems is the best course of action. more

Patching is Hard

There are many news reports of a ransomware worm. Much of the National Health Service in the UK has been hit; so has FedEx. The patch for the flaw exploited by this malware has been out for a while, but many companies haven't installed it. Naturally, this has prompted a lot of victim-blaming: they should have patched their systems. Yes, they should have, but many didn't. Why not? Because patching is very hard and very risk, and the more complex your systems are, the harder and riskier it is. more

Sorry, Not Sorry: WHOIS Data Must Remain Public

In March, I posted a call to action to those of us in the community who have the inclination to fight against a movement to redact information critical to anti-abuse research. Today, I felt compelled to react to some of the discussions on the ICANN discussion list dedicated to the issue of WHOIS reform: Sorry, not sorry: I work every working hour of the day to protect literally hundreds of millions of users from privacy violating spam, phish, malware, and support scams. more

While Cyberspace Is Entering an Era of Warring States, There Remains a Chance to Make a Difference

For the non-state actors who are making efforts to approach cybersecurity issue in a different and creative way, the state actors, however, have given clear signs that they have exhausted their patience and insisted on doing things alone by bringing traditional old tricks back into cyberspace. This is exemplified in the bilateral meeting of two cyber sovereigntists - the Chinese and U.S. presidents on April 6-7, and in the multilateral G7 Declaration on Responsible States Behavior in Cyberspace on April 11. more

Loudmouths Wanted for ICANN WHOIS Replacement Work

TL;DR? It's worth reading, BUT, if not -- ICANN has yet another group looking at WHOIS, and there is a huge push to redact it to nothing. I spend easily half my day in WHOIS data fighting online crime, losing it would not make my job harder, it will make it impossible. PLEASE JOIN THE ICANN GROUP and help us fight back against people who are fighting in favour of crime. more

Digital Geneva Convention: Multilateral Treaty, Multistakeholder Implementation

Microsoft's call for a Digital Geneva Convention, outlined in Smith's blog post, has attracted the attention of the digital policy community. Only two years ago, it would have been unthinkable for an Internet company to invite governments to adopt a digital convention. Microsoft has crossed this Rubicon in global digital politics by proposing a Digital Geneva Convention which should 'commit governments to avoiding cyber-attacks that target the private sector or critical infrastructure or the use of hacking to steal intellectual property'. more

We Urgently Need a New Internet

Let's be honest about it. Nobody -- including those very clever people that were present at its birth -- had the slightest idea what impact the internet would have in only a few decades after its invention. The internet has now penetrated every single element of our society and of our economy, and if we look at how complex, varied and historically different our societies are, it is no wonder that we are running into serious problems with the current version of our internet. more

Mitigating DDoS

Your first line of defense to any DDoS, at least on the network side, should be to disperse the traffic across as many resources as you can. Basic math implies that if you have fifteen entry points, and each entry point is capable of supporting 10g of traffic, then you should be able to simply absorb a 100g DDoS attack while still leaving 50g of overhead for real traffic... Dispersing a DDoS in this way may impact performance -- but taking bandwidth and resources down is almost always the wrong way to react to a DDoS attack. But what if you cannot, for some reason, disperse the attack? more
