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

Millions of email warnings were sent out by Marriot on Friday to warn customers about the massive data breach which has affected close to half a billion guest data. more

Hackers Behind Marriott Breach Left Clues Suggesting Link to Chinese Government

The Economics of Hacking an Election

There have been many news stories of late about potential attacks on the American electoral system. Which attacks are actually serious? As always, the answer depends on economics. There are two assertions I'll make up front. First, the attacker -- any attacker -- is resource-limited. They may have vast resources, and in particular, they may have more resources than the defenders -- but they're still limited. Why? more

Russian Hackers Have Penetrated U.S. Electric Utilities

U.S. federal government officials have revealed Russian hackers have been able to gain access to the networks of electric utilities in the country, according to a report by The Wall Street Journal. more

Why You Must Learn to Love DNSSEC

It's been nearly two months since the high profile BGP hijack attack against MyEtherwallet, where crypto thieves used BGP leaks to hijack MEW's name servers, which were on Amazon's Route53, and inserted their own fake name servers which directed victims to their own fake wallet site, thereby draining some people's wallets. It generated a lot of discussion at the time... What isn't fully appreciated is that attack has, in fact, changed the game somewhat... more

Schneier and Kerr on Encryption Workarounds

Bruce Schneier is a famous cryptography expert and Orin Kerr a famous cyberlaw professor. Together they've published a law journal article on Encryption Workarounds. It's intended for lawyers so it's quite accessible to non-technical readers. The article starts with a summary of how encryption works, and then goes through six workarounds to get the text of an encrypted message. more

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
