Google Docs used in latest spam run

Google Doc SpamSpam researchers have discovered a recent run of unwanted messages using Google’s Web-based word processor and even testing their campaigns using Google analytical tools.

MessageLabs spokesperson Matt Sergeant, said the spam messages are successful in getting through most enterprise email filters. The messages don’t contain content, only a link that takes recipients to a Google Docs file. Once opened the file touts the all too familiar pharmaceuticals hyped in many spam campaigns.

“This is another method that spammers have found of hosting a website in a place that’s bulletproof basically,” Sergeant said.

Google has labeled the hosted file as being registered as spam. The good news is that Google Docs is still in its infancy, so there aren’t a lot of people using them in a corporate setting, Sergeant told me. So far the messages have come in very small numbers, but large enough that they triggered an alert at MessageLabs.

Spammers exploit social networking sites

Users of social networking sites may be irritated to find that an increasing number of invitations to be a friend or contact turn out to be ads.

Spammers are turning their attention to social networking sites to hawk their products, according to Cloudmark, a messaging security company. As email antispam technology has improved, spammers have branched out to other areas, said Adam O’Donnell, director of emerging technology at Cloudmark. “The social networking side provided a fertile ground for spammers,” he said.

Junk emailers are using multiple messaging vectors available on social networking sites, including direct messaging to friends, bulletin board posts and profiles, O’Donnell said. For example, a spammer will create a profile, which includes a link to a porn or dating site, then invites a bunch of people to be their friend or contact.

In a recent six-month period, Cloudmark tracked a 300 percent increase in spam on a large social networking site that it works with. Also, at several major social networking sites, about one-third of new accounts created are fraudulent, designed for spam and other attacks, the company said.

On Monday, Cloudmark released what it said was the only commercial product to combat spam, phishing and other attacks on social networks. Cloudmark Authority for Social Networking Providers, which extends Cloudmark’s carrier-grade platform, is designed to protect all communication channels on a social networking site. The company said the technology has been deployed at one of the largest social networking sites, but wouldn’t identify it.

There’s no spam filter that end users can deploy to protect themselves on social networking sites, O’Donnell said. Some sites like LinkedIn are used as business tools, he said, adding, “If it came to a point on social networks where 80 percent of inbound content is spam, they’re no longer a useful business tool.”

Jamz Yaneza, a senior threat researcher at Trend Micro who uses several social networking sites including Facebook and MySpace, said he’s noticed an increase in friend invitations that push products. There have been a lot of exploits against social networking sites, he said, citing last year’s hack of singer Alicia Keys’ MySpace page.

Paul Ferguson, also a threat researcher at Trend Micro, said the growth of users on social networking sites “far outpaces their ability to keep the platform secure.” He added, “The back-end mechanisms that allow the interactivity also allow people to use them for malicious purposes.”

 

 

 

 

Fighting security FUD

Bill BrennerI recently tripped over a blog write-up from independent analyst Eric Ogren about his irritation with security vendors using FUD to sell products. It’s an older posting from 2006 but his message is as relevant today as it was two years ago.

Building his case around a threat report Websense released at the time, he wrote, “I’m not sure that the world is better off with yet another security vendor telling us that Phishing, malicious websites, malicious code, hacking tools, P2P, IM and Chat attacks have all increased.”

He dismissed the report as FUD marketing designed to create demand for security products, but that he believed the reports could actually have the opposite effect by pointing out the futility of security products to stop attacks.

He’s not the first security expert to rail against the FUD factor. Security luminary Bruce Schneier has devoted huge chunks of his time speaking out against security ‘theatre’ — policies and products that are more about offering the perception of security rather than addressing the actual risks.

And, rightly or wrongly, the Apple crowd is constantly crying FUD whenever something is written about a security flaw or malware affecting their beloved Macs.

I bring up the issue because it’s long been a source of irritation for me. As a security writer, I’m constantly buried beneath tons of voicemail and email from vendors looking for attention, and the PR machinery almost always uses FUD to make a case for buying the latest compliance-out-of-the-box appliance or the “first of its kind” bot/spyware/worm/common cold zapper.

Along the way, the PR community likes to invent new words or phrases to define the threat, many of which start with the letters “ph” (phishing, pharming, phlooding).

I’ve been looking back through four years of writing for the sake of nostalgia. The big thing that strikes me is that we’ve written a lot of stories about the latest flaw or exploit and someone is always banging on the alarm bell with a hammer.

In the final analysis, it’s prudent to flag the latest flaws and exploits because IT security professionals need to be aware of these things and incorporate the information into their patch management process. Heck, alerting them to these things is what we’re here for. But the tone and level of alarm that should go into these stories is always something we wrestle with.

Everyone has a role to play in information security, from the IT pros to the vendors, analysts and media. But from the content I look back on, I see little evidence that vendor-generated fear has ever made a difference.

Warnings about some flaw or exploit opening the door for a catastrophic Internet-ending event are never followed by the big doom. On the other side of the spectrum, the epidemic of data security breaches shows that all the FUD and security spending in the world can’t prevent the bad guys from punching through. The recent Hannaford supermarkets breach proves you can respond to the fear and spend a lot of money on new technology and still get whacked.

I recently asked Rhode Island-based network engineer Edward Ziots whether he jumps at every exploit warning. Here’s what he told me by email:

We don’t jump, it would be imprudent to do so. Basically I read up on how the exploit works, even look at the code offline to ascertain if it would be available to be downloaded or how much effort would it take to be in a working exploit. Next, you basically need to adjust your risk assessment based on the controls you have in house, and how many systems could be affected and in what manner.

“Lastly communicate the adjusted risk assessment to management, security and await decision on whether to raise priority for patching, or to deploy other security measures to mitigate until all systems can be patched.

“Honestly, it makes it very difficult with exploit code in the wild and reports of working exploits not to raise your risk level and deploy extra manpower and time and effort to get all systems patched. It’s just due diligence.”

My advice is to take the FUD with a grain of salt and remember that while cyberspace is a dangerous place and you’ll sometimes have to raise your level of alertness as Ziots does, most enterprises will survive with the proper mix of security tools, policies and a calm awareness of the risks.

Flaw fixes for Firefox, Mac

A couple of notable security fixes to flag this morning:

First, Apple has patched the Safari Web browser flaw that famously earned a researcher $10,000 at the CanSecWest conference last month. Independent Security Evaluators researcher Charlie Miller used the vulnerability to compromise a MacBook Air laptop. The flaw is rooted in the WebKit open-source HTML rendering engine Safari and several other Mac OS X programs use.

Next, Mozilla has released Firefox 2.0.0.14, fixing a critical security hole in the JavaScript engine of Firefox. The advisory said, “Fixes for security problems in the JavaScript engine described in MFSA 2008-15 (CVE-2008-1237) introduced a stability problem, where some users experienced crashes during JavaScript garbage collection. This is being fixed primarily to address stability concerns. We have no demonstration that this particular crash is exploitable but are issuing this advisory because some crashes of this type have been shown to be exploitable in the past.”

RealPlayer flaw being actively exploited

Symantec researchers issued a warning about active attacks in the wild on a RealPlayer ActiveX control vulnerability. The problem affects RealPlayer 11.

“So far impacted sites have ranged from forums, to webmail, to news agencies,” Symantec said in its Security Response blog.

Security researcher Elazar Broad, who discovered the vulnerability, said it could allow an attacker to execute code and gain access to a victim’s machine. Broad posted a RealPlayer workaround until a patch is issued.

New Apple Air notebook vaporized in PWN2OWN contest

Apple is claiming that it’s new Air is the world’s thinnest notebook PC. Luckily, it didn’t make any claims about the new machine’s security, because it only took Charlie Miller of Independent Security Evaluators a few minutes on Thursday to gain control of a new Air in the annual Pwn2Own hacking contest at CanSecWest. Miller was able to exploit an unpatched vulnerability in Apple’s Safari browser to compromise the notebook, winning himself a $10,000 prize, as well as the Air itself. Not a bad haul for a few minutes of work.

This year’s contest is a bit different from last year’s edition, in that there are three separate machines up for grabs. In addition to the Air, TippingPoint, which sponsors the contest, put up two other machines, one each running Vista and Ubuntu. After Miller cracked the laptop, he turned over details of the attack to TippingPoint, which disclosed it to Apple.

Researcher: IFrame redirect attacks escalate

It’s been a couple of weeks since security researcher Dancho Danchev raised the red flag about IFrame redirects attackers have been using to corrupt hundreds of thousands of websites, and how the likely culprit is the infamous hacking group known as the Russian Business Network (RBN).

Overnight, Danchev emailed me with an update, and it doesn’t look good. Based on his ongoing investigation, the attacks seem to be continuing unabated.

The latest high-profile sites getting targeted includes usatoday.com, abcnews.com, news.com, target.com, packardbell.com, Walmart.com, Rediff.com, Miamiherald.com, Bloomingdales.com, Patentstorm.us, Webshots.com, Sears.com, Forbes.com, Ugo.com, Bartleby.com, Linkedwords.com, Circuitcity.com, Allwords.com, Blogdigger.com, Epinions.com, Buyersindex.com, Jcpenney.com, Nakido.com, Uvm.edu, hobbes.nmsu.edu, jurist.law.pitt.edu, boisestate.edu.

“After another week of monitoring the campaign and the type of latest malware and sites targeted, the campaign is still up and running, poisoning what looks like over a million search queries with loadable IFrames, whose loading state entirely relies on the site’s Web application security practices - or the lack of,” Danchev wrote in his blog. ”

The data breach that hit home

Bill BrennerCovering the security breach at Hannaford Bros. Supermarkets this week was a particularly interesting experience for me. Unlike the other breaches I’ve written about, this one really hit me where I live.

Of course, the bank did send me a new debit card after my old one was compromised in the TJX data breach, but that’s only because of one purchase I made there during the period when the data raids were in progress.

I shop at Hannaford’s every week. Even though there are several supermarkets closer to home, I’ve been making the longer trek to the store in Hampstead, N.H., because I found the prices and food quality better than the others. Despite, the breach, I won’t stop shopping there. My bank was quick to issue me a new card and I think the retailer will do what’s necessary to prevent a repeat. Of course, the company will lose a lot of money to fines and lawsuits in the meantime. Security Blog Log

Of course, after any data breach it’s important to explore how it happened and what the affected company could have done better from the outset, and Hannaford’s is no exception.

I found plenty of security bloggers doing just that. Here’s some wisdom from two blogs high on my favorites list:

Rich Mogull, former Gartner analyst and founder of security consultancy Securosis, wrote in his blog that since the information was stolen during the authorization process and was distributed over many locations, a compromise of the central authorizations system or the credit card processor is the likely source. “It could be as simple as sniffing unencrypted communications, or a more complex compromise of a database or application,” he said. “My money is 70% on sniffing, 30% on something in the database.”

Of Hannaford’s claim that no personal data such as names, addresses or telephone numbers were divulged — just account numbers, Mogull wrote, “This can’t be true. Without names, the card numbers are unusable.”

Mogull also used Hannaford’s PCI DSS compliance as an example of how he believes “PCI is worthless” if the chain was allowed to be ruled compliant in the first place.

“The fraud was detected by the banks or credit card companies, then it took a little under two weeks to contain,” he wrote. “Not great, and indicative of either a little sophistication on the attacker’s part, or a lack of sophistication on Hannaford’s part. How to prevent this? We won’t know until more information is out, but since they shouldn’t be PCI compliant if they transmitted credit card numbers in the clear, perhaps my guess of sniffing is off. I’m still laying odds on that, and if so, encryption is the answer.”

Security blogger Martin McKeay wrote of a silver lining in the Hannaford’s breach.

“Hannaford does not associate card numbers and expiration dates with the cardholder names and addresses,” he noted. “This in a day when your local grocery store offers you a discount if you’ll just enter your phone number at the PIN pad so they can track every single purchase you make and send you a personalized weekly ad. Most stores would have had card numbers, your home address, the names of all of your relations and possibly the name your teacher in first grade. Well, maybe not the last one, but they would have every purchase of every embarrassing purchase you’ve ever made.”

The downside to this lack of association between card numbers and cardholder names, he wrote, is that they have no way of knowing who should be contacted in the breach. He said he’s not sure if that will absolve Hannaford’s of having to contact anyone or make it necessary for them to contact all of their customers. They probably haven’t figured that one out yet either, he said.

Good points from both. I’ll end by saying that the big reason Hannaford’s won’t lose me as a customer is because I see them as more of a victim than a villain.

Through my own reporting on PCI DSS compliance I know the company had made investments to bolster the security of its point-of-sale machinery and wireless set-up.

Some are making much of the fact that this breach happened even though Hannaford’s was PCI compliant. Surely, they say, this speaks to the weaknesses of PCI DSS itself. I actually explored that angle in the wake of the TJX breach, and most of the analysts, IT pros and vendors I talked to defended the security standard. After all, it turned out, TJX was nowhere near being where it needed to be for PCI compliance.

Regardless of what one thinks of PCI DSS, it does appear that Hannaford’s was and still is working to improve its security.

But as a police officer once told me after my house was burglarized despite the burglar alarm we had installed, if the thief wants to get in badly enough, they’ll find a way.
