1.3 Tbps DDoS Attack Against GitHub is Largest Attack Seen to Date, Says Akamai

According to Akamai, the incident was the largest attack seen to date, "more than twice the size of the September 2016 attacks that announced the Mirai botnet and possibly the largest DDoS attack publicly disclosed." more

‘First True’ Native IPv6 DDoS Attack Reported

Possibly the first documented native IPv6 DDoS attack reported today suggests a DNS dictionary attack which originated from around 1,900 different native IPv6 hosts, on more than 650 different networks. more

Why Is It So Hard to Run a Bitcoin Exchange?

One of the chronic features of the Bitcoin landscape is that Bitcoin exchanges screw up and fail, starting with Mt. Gox. There's nothing conceptually very hard about running an exchange, so what's the problem? The first problem is that Bitcoin and other blockchains are by design completely unforgiving. If there is a bug in your software which lets people steal coins, too bad, nothing to be done. more

Voluntary Reporting of Cybersecurity Incidents

One of the problems with trying to secure systems is the lack of knowledge in the community about what has or hasn't worked. I'm on record as calling for an analog to the National Transportation Safety Board: a government agency that investigates major outages and publishes the results. In the current, deregulatory political climate, though, that isn't going to happen. But how about a voluntary system? more

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

Dell Loses Key Customer Support Domain Name for a Month, Site Exposed to Questionable Content

The website designated by Dell Inc. to help customers recover from malicious software and other computer maladies may have been hijacked for a few weeks this summer by people who specialize in deploying said malware, reports Brian Krebs in KrebsOnSecurity. 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

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

Cloud Leak Exposes at least 14 Million Verizon Subscribers, Phone Numbers and Account PINs Included

A Verizon partner is reported to have exposed millions of Verizon customer accounts due to a misconfigured cloud-based file. more

Phishing: the Worst of Times in the DNS

The Anti-Phishing Working Group has released its latest Global Phishing Survey, written by myself and Rod Rasmussen. This report comprehensively examines a large data set of more than 250,000 confirmed phishing attacks detected in 2015 and 2016. By analyzing this cybercrime activity, we have learned more about what phishers have been doing, and how they have done it. Unfortunately, there's more phishing than ever, and phishers are registering more domain names than ever. 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

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

Encryption and Securing Our Digital Economy

As G20 leaders from around the world gather this week, Germany wants them to agree to a concrete plan -- one that includes affordable Internet access across the world by 2025, common technical standards and a focus on digital learning. Today, the G20 economies, like so many other economies around the world, are digital and interconnected. Digital services have opened up new avenues for sustainable economic growth. more

Three Layers of China’s International Strategy on Cyberspace

China's newly released International Strategy on Cyberspace is marked by three distinctive layers with different degree of priority: (1) sovereignty (or cybersecurity, or UN Charter), (2) globalization (or digital economy, or WTO rules), and (3) fundamental freedoms (or human rights, or UDHR). The good point of the strategy is that it tries to make the three layers peacefully co-exist in one document. The failure, however, lies in the intentional ranking of relevance/importance of the three layers... more

Considering a Vulnerability Disclosure Program? Recent Push Raises Questions for General Counsel

Several years ago, vulnerability disclosure programs, also called "bug bounty" programs, were novel and eyed with suspicion. Given sensitivities and potential liabilities, companies are wary of public disclosure and hackers seeking to exploit research. When a hacker presented a flaw to a company, the company was more likely to be concerned about taking legal action than making a public announcement or offering a reward. That is changing. more
