Unexpected Behaviour Observed With DNS Root Servers After Cryptographic Change

The DNS root servers were reported by Verisign to be under unexpected attack from name servers across the Internet following ICANN's recent changes to their cryptographic master keys. more

Putting Cyber Threats Into Perspective

As society uses more digital technologies we are increasingly also faced with its problems. Most of us will have some horror stories to tell about using computers, smartphones, and the internet. But this hasn't stopped us from using the technology more and more. I believe that most people would say that their lives would be worse without technology -- in developed countries but equally in the developing world. more

Researchers Demonstrate Serious Privacy Attacks on 4G and 5G Protocols

A group of academic researchers have revealed a design weakness in the 4G/5G protocol which can be exploited by an attacker to identify the victim's presence in a particular cell area just from the victim's soft-identity such as phone number and Twitter handle. more

Microsoft is Abandoning SHA-1 Hashes for Updates - But Why?

Microsoft is shipping a patch to eliminate SHA-1 hashes from its update process. There's nothing wrong with eliminating SHA-1 - but their reasoning may be very interesting. SHA-1 is a "cryptographic hash function". That is, it takes an input file of any size and outputs 20 bytes. An essential property of cryptographic hash functions is that in practice (though obviously not in theory), no two files should have the same hash value unless the files are identical. 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

Strange Email Used to Inform Marriott Customers About the Massive Data Breach

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

Hackers behind the massive data breach of the hotel group Marriott International Inc have left clues suggesting ties to the Chinese government intelligence-gathering operation. more

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
