Is Blockchain Causing More Cybersecurity Attacks in the Financial Industry?

There's a lot of misunderstanding about blockchain. A recent study by HSBC, for example, found that 59 percent of customers around the world had never heard of it. Yet, while that alone is quite telling, it's probably more alarming to consider the fact that very same poll revealed that 80 percent of people who had hard of blockchain did not understand what it is. This level of confusion isn't confined to the general population either. more

1 Terabit DDoS Attacks Become a Reality; Reflecting on Five Years of Reflections

Reflection amplification is a technique that allows cyber attackers to both magnify the amount of malicious traffic they can generate, and obfuscate the sources of that attack traffic. For the past five years, this combination has been irresistible to attackers, and for good reason. This simple capability, of turning small requests into larger, 'amplified' responses, changed the Distributed Denial of Service (DDoS) attack landscape dramatically. 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

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

Humming an Open Internet Demise in London?

In mid-March, the group dubbed by Wired Magazine 20 years ago as Crypto-Rebels and Anarchists - the IETF - is meeting in London. With what is likely some loud humming, the activists will likely seek to rain mayhem upon the world of network and societal security using extreme end-to-end encryption, and collaterally diminish some remaining vestiges of an "open internet." Ironically, the IETF uses what has become known as the "NRA defence": extreme encryption doesn't cause harm, criminals and terrorists do. more

Hackers Hijack DNS Server for Cyrptocurrency Wallet BlackWallet, Over $400K Stolen From Users

Unknown hackers (or hacker) have hijacked the DNS server for BlackWallet.co, a web-based wallet application for the Stellar Lumen cryptocurrency (XLM). more

WHOIS: How Could I Have Been So Blind?

A colleague was recently commenting on an article by Michele Neylon "European Data Protection Authorities Send Clear Message to ICANN" citing the EU Data Commissioners of the Article 29 Working Party, the grouping a determinate factor In the impending death of WHOIS. He is on point when he said: What the European Data Protection authorities have not yet put together is that the protection of people's mental integrity on the Internet is not solely due to the action of law enforcement... 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

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
