Thoughts on the Best Western Compromise

The Sunday Herald reported on Sunday that Best Western was struck by a trojan attack that lead to the possible compromise of about 8 million victims. There is some debate as to the extent of the breach and not a small amount of rumor going around. I'm not entirely disposed to trust corporate press releases for the facts, nor am I going to blindly accept claims of security researchers whose first call is to the PR team when discovering a problem. That said, here is what seems to be the agreed upon facts... more

Searching for Truth in DKIM: Part 4 of 5

Once you've determined that you can trust the signer of a message, as we discussed in part 3, it's easy to extrapolate that various portions of the message are equally trustworthy. For example, when there's a valid DKIM signature, we might assume that the From: header isn't spoofed. But in reality, DKIM only tells us two basic things... more

Quo Vadis ICANN?

The short history of Internet Governance is full of errors, failures, and - mainly - omissions. Despite the shortcomings, we also must acknowledge the achievements of past and present internet governance efforts. In particular, ICANN and its stakeholder constituencies have delivered on the mandate of a stable, secure and resilient Internet. Working with the IANA, IAB and IETF, the operational functions of IP addresses, and the Protocol Assignment and DNS must be seen as an unqualified success. more

Credit Card Breaches a Salutary Lesson for DNSSEC Adoption

Maintaining an 150 year old house requires two things, a lot of time and a lot of trips to the hardware store. Since the closest hardware store to my house is Home Depot, it is rare that a weekend passes without at least one trip to Home Depot. So now in the wake of the Home Depot data breach I am through no fault of my own in a situation where any or all of the bank cards I use regularly could be cancelled if the issuer decides they might be compromised. And this is not the first time this has happened to me this year. more

US Justice Department and FBI Dismantle Long-Running Russian State-Sponsored Cyber-Espionage Operation Targeting NATO

The United States Department of Justice has announced that it has neutralized a global network of computers compromised by malware called "Snake," which the U.S. government attributes to a unit within Center 16 of the Federal Security Service of the Russian Federation (FSB). more

NSA to Stop Collecting American Emails To and From Overseas

U.S. National Security Agency (NSA) will halt its controversial warrantless surveillance program which collects Americans' emails and texts sent to and from people overseas and that mention a foreigner under surveillance, according to a New York Times report today. more

Cybersecurity Is Failing Big-Time and This Is Hard to Fix

It has become clear that having a big cybersecurity war room is not enough to deliver true end-to-end security throughout the complex networks, systems and structures on which our modern society is based. Furthermore, looking at the forever changing draconian government interventions in this space, it is also obvious that they are often stabbing in the dark. more

In a speech at the Internet Policy Research Initiative at MIT, British intelligence agency GCHQ director Robert Hannigan said Monday that law enforcement and intelligence officials want only targeted ways to stop what he called "abuse of encryption" by ISIS and other terrorists and criminals. more

I’m Shocked, Shocked to Find There’s Cryptanalysis Going On Here (Your plaintext, sir.)

There's been a lot of media attention in the last few days to a wonderful research paper on the weakness of 1024-bit Diffie-Hellman and on how the NSA can (and possibly does) exploit this. People seem shocked about the problem and appalled that the NSA would actually exploit it. Neither reaction is right. In the first place, the limitations of 1024-bit Diffie-Hellman have been known for a long time. RFC 3766, published in 2004, noted that a 1228-bit modulus had less than 80 bits of strength. That's clearly too little. more

Brand Protection Beyond the “Whack-a-Mole” Approach

I recently shared at a conference how a seasoned brand and fraud expert from one of the world's largest global financial institutions lamented a major attack where multiple fraudulent websites would pop up every single day. All attacks were launched from the same registrar and web hosting company, and no matter how much they reached out to these providers, they received the same reply: "we will pass on your request to the registrant or site owner," and then nothing happened. more

The Countdown Has Started – Here Come One-Year Digital Certificate Life Cycles

Apple announced its decision to trust only one-year digital certificates on its Safari browser in February 2020. This decision created a domino effect, with Mozilla and Google following suit; certificate providers announced they would not issue two-year certificates after Aug. 19, 2020. We wrote an article in March to help brands to prepare for this change. more

The [Dot]Brand Tribes - Part 3

In part two of The [Dot] Brand Tribes we argued that introducing new branded generic Top-Level Domains (gTLDs) would bring value to brand owners and have positive effects on customer recognition. In this last post we'll continue that theme and talk about how brand owners can come together to provide shared spaces using the banking industry as an example. more
