Declan McCullagh recently opined that the "FBI [and the] DEA warn [that] IPv6 could shield criminals from police." His post was picked-up relatively widely in the past few days, with the headlines adding more hyperbole along the way. So just how real is this threat? Let's take a look. more
According to press reports, DHS is going to require federal computer contractors to scan for holes and start patching them within 72 hours. Is this feasible? It's certainly a useful goal. It's also extremely likely that it will take some important sites or applications off the air on occasion - patches are sometimes buggy (this is just the latest instance I've noticed), or they break a (typically non-guaranteeed or even accidental) feature that some critical software depends on. more
At the end of January, the DMARC (Domain-based Message Authentication, Reporting & Conformance) specification was publicly announced and resulted in widespread media coverage, blog posts and discussion. Since that time various individuals and organizations have been working on writing code for DMARC validators and report parsers. The dmarc-discuss list has been fairly active as various questions and issues have been raised and clarified. Now it is time to see how well the various implementations play together in live testing. more
The technical press is full of reports about the leak of a hashed password file from LinkedIn. Worse yet, we hear, the hashes weren't salted. The situation is probably both better and worse than it would appear; in any event, it's more complicated. more
This may or may not come as a shock to some of you, but ICANN's contract with the Domain Name Registrars, in terms of WHOIS inaccuracy is not enforceable. Bear with me. The ability of ICANN to enforce against a Registrar who fails to correct or delete a domain with false WHOIS does not exist. more
Only two years after signing the DNS root zone, the powerful lure of a secure global infrastructure for data distribution is starting to reveal itself. It is illustrated clearly by two proposed technical standardizations that seek to leverage secure DNS. To some degree these developments highlight the strength of DNS institutions and how they might fill gaps elsewhere in the Internet's governance. But an increasing reliance upon and concentration of power in the DNS also makes getting its global governance correct even more important. more
Eugene Kaspersky has warned global leaders that the world needs international agreements about cyber-weapons in the same way as it needs agreements about nuclear or biological weaponry. The chairman and chief executive officer of Kaspersky Lab, warned delegates at CeBIT Australia that cyber-warfare and terrorism was the number one internet threat facing the world today. He said the Stuxnet industrial virus had demonstrated that cyber-weapons were capable of damaging physical infrastructure, and were "a thousand times cheaper" to develop than conventional weaponry. more
Mobile networks aren't usually thought of as sources of spam, but a quick look at some of the resources that track spam reveals they actually are. This is counter intuitive at first glance because when most people think of mobile they think of smartphones, and those aren't known to be sources of spam (at least not yet). What's really going on is PCs connected to mobile networks with air cards, or tethered with a smartphone where it's permissible, are the culprits more
In case you haven't been watching cyber news recently, last week various security researchers published that Macs were infected by the Flashback Trojan and that the total number of infections worldwide was 600,000. This number was published by a couple of blogs. I debated writing about this topic since we had a previous Mac outbreak last year that initially spiked up, caused Apple to go into denial about the affair before issuing a fix, and then the malware kind of went away. Will this follow the same pattern? more
Like the scene of a movie in which a biblical character holds back the mighty sea and is about to release the tide against his foes, BYOD has become a force of nature poised to flood those charged with keeping corporate systems secure. Despite years of practice hardening systems and enforcing policies that restrict what can and can't be done within the corporate network, businesses are under increasing (if not insurmountable) pressure to allow a diversifying number of personal devices to connect to their networks and be used for business operations. more
Most of the good thrillers I tend to watch have spies and assassins in them for some diabolical reason. In those movies you'll often find their target, the Archduke of Villainess, holed up in some remote local and the spy has to fake an identity in order to penetrate the layers of defense. Almost without exception the spy enters the country using a fake passport; relying upon a passport from any country other than their own... So, with that bit of non-fiction in mind, why do so many people automatically assume that cyber-attacks sourced from IP addresses within China are targeted, state-sponsored, attacks? more
This morning, Global Payments held a conference call with investors and analysts covering their earlier breach announcement and projected earnings. Global Payments had also released an update advisory yesterday stating that "the company believes that the affected portion of its processing system is confined to North America and less than 1,500,000 card numbers have been exported" and that only Track 2 card data may have been stolen. more
In our continuing review of Rogue Registrars we have stumbled upon on a very elaborate fake banking site for "Swiss Bank" or "Bank of Switzerland". To the casual Internet consumer this site probably appears legitimate, but a number of clues tip off the fraud. Phishing sites are everywhere so this does not immediately raise eyebrows until you review the Thick WHOIS record for the domain. more
One fine night in November 2011 I got an opportunity to get my hands dirty, working on a project for the United States Federal Bureau of Investigation (FBI). They were planning to seize a bunch of computing assets in New York City that were being used as part of a criminal empire that we called "DNS Changer" since that was the name of the software this gang used to infect a half million or so computers. more
On January 18, 2012, Comcast customers found they could not access the NASA.gov website. Some users assumed that Comcast was deliberately blocking the website or that NASA, like Wikipedia and Reddit, was participating in the "blackout" protests against the Stop Online Piracy Act (SOPA) going on that day. As it turned out, the truth was much less exciting, but it offers important lessons about DNSSEC. more
