Reducing the Risks of BYOD with DNS-Based Security Intelligence; Part 1: Understanding the Risks

Ah, BYOD. How I love thee. BYOD, or "Bring Your Own Device", gives me choices. I can use a device at work I actually like and am most effective with. (How did I ever get by without my iPad?) But BYOD comes with challenges. Personal devices can be infected with malware. Once they're connected to an enterprise's network, they can be controlled by a bot master to hijack enterprise resources and wreak havoc as part of a botnet. more

Follow a Phishing Case in Real Time: postfinances.com / Swiss Post

It is just another phishing case. Why should I care? I happened to receive my own copy of the phishing email message. Most Internet users will just smile bitterly before deleting it. I checked it to see why it had gone through the spam filters. It had no URL in the text but a reply-to address. So it needed a valid domain name, and had one: postfinances.com. PostFinance (without trailing "s") is the payment system of the Swiss Post. It has millions of users. more

IPv6 Presents a Security Paradox for the Network

The capabilities IPv6 provides will enhance online security, but the shift to the new Internet address scheme may also present risks if not properly managed. Previously, Internet security was largely an after-thought for the early Internet, as its primary purpose was to facilitate open, end-to-end, any-to-any communications and information exchange for bridging and accelerating research efforts. Today, we have a much more complex online ecosystem that spans billions of users across the globe and serves not only as an engine for e-commerce, but as an engine for all commerce. more

Google Dumps Illicit Pharmacy Advertisements

Garth Bruen writes: Within the next few weeks Google plans to update its pharmacy policy which will restrict pharmacy advertisements. Once in effect, the updated policy will only allow VIPPS and CIPA certified pharmacies to advertise. Additionally these pharmacies can only target ads within their country. more

Cyber Criminals Infiltrate Even Small Businesses

I read an interesting article in the Wall Street Journal today entitled Cyber Criminals Sniff out Vulnerable Firms. It's a story of a small business owner in New York whose company was broken into by cyber criminals and stole $1.2 million from its bank accounts, although the owner was able to later recover about $800,000 of that. The moral of the story is that small businesses feel like they are not a major target for online thefts like these. more

Is IPv6 a Boon to Criminals and Foe to the FBI?

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

Fixing Holes

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

Interoperability Testing Event for DMARC Email Anti-Spoofing Specification

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

Password Leaks

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

ICANN’s Contract Not Enforceable on WHOIS Accuracy

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

If You Build It, They Will Come.

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: World Needs International Agreements On Cyber-Weapons

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

Spam from Mobile Networks? Who Woulda Thought…

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

Mac Hit by Another Wave of Malware… Users in Denial?

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

BYOD Woes and Worries

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
