20:19 Study: 637 million Google users surfing with insecure browserAccording to a new study from researchers at Google, IBM and ETH Zurich, there are about 637 million Google users surfing the Internet with a vulnerable Web browser.
Using data from Google search queries and security vulnerability aggregator Secunia, the study (HTML or PDF) found that a whopping 45 percent of Google users “were not using [...] >>>
17:17 Dont lose your laptop at the airport!I don’t know about other travelers, but losing my laptop while flying to or from a client site is one of my bigger fears. I have so much sensitive information on my drive that I’d panic if it was out of my site for more than the thirty seconds it takes to X-ray my [...] >>>

14:05 About that cellular interferenceSo… maybe it is a real problem. Pedram Amini (top picture on the right), noted researcher and reverse engineer, posted an article to the Tipping Point DVLabs blog on some interesting observations he made on cellular interference. From the article, Pedram comments on the discovery:
“I had placed my iPhone on the laptop just below the [...] >>>
"It turns out that if a user has files that are encrypted by Gpcode and versions of those same files that are unencrypted, then the pairs of files (the encrypted and corresponding unencrypted file) can be used to restore other files on the victim machine. This is the method that the StopGpcode2 tool uses.
Where can these unencrypted files be found? They may be the result of using PhotoRec. Moreover, these files may be found in a backup storage or on removable media (e.g., the original files of photographs copied to the hard disk of a computer that has been attacked by Gpcode may still be on a cameras memory card). Unencrypted files may also have been saved somewhere on a network resource (e.g., films or video clips on a public server) that the Gpcode virus has not reached."
As the customer support desk behind GPcode pointed out in an interview, the malware is prone to evolve, and the simplistic file deletion process will be replaced by secure file deletion in order to render all data recovery tols useless, unless of course backups of the affected data are available. They often aren't, and depending on the importance of the files encrypted, the successful ransom is all a matter of the momentum.
"A person, presumably the author of Gpcode, contacted at one of the e-mail addresses left behind by the program stated that future development efforts will likely increase the key size to 4,096 bits, "if AV companies or other (people) crack the current key, but (that's) impossible. The self-proclaimed author, who used the name "Daniel Robertson," also said that other standard techniques to defeat antivirus will be added, including polymorphic encryption, anti-heuristic features and the ability to self propagate, turning the program into a computer virus. It well pays back itself," he said"
June's threatscape that I'll summarize in this post based on all the research conducted during the month, was a very vibrant one. With the return of GPcode, a remotely exploitable flaw in the Zeus crimeware kit allowing both, researchers and malicious parties to assess the severity of a particular banker malware campaign, the increasing use of malicious doorways next to ICANN and IANA's DNS hijacking, all speak for themselves and how diverse the threats and, of course, the abilities to maintain a decent situatiational awareness about what's going on have become.
01. U.K's Crime Reduction Portal Hosting Phishing Pages - nothing new here since vulnerable sites are to be "remotely file included" and SQL injected to locally host anything on behalf of a malicious party. Risk and responsibility forwarding is one thing, but having a crime reduction portal hosting phishing pages is entirely another. The phishing pages was shut down in less than 12 hours upon notification
02. Price Discrimination in the Market for Stolen Credit Cards - Tracking down "yet another stolen credit cards for sale" service in the wild, the price discremination that they applied greatly reflects the current lack of transpararency for a potential buyer of stolen credit cards, and how higher profit margins are driving the entire business model. With script kiddies running their own botnets and undermining the sophisticated botnet master's high profit margin business model by undercutting their prices, stolen credit cards are not what they used to be - an exclussive good. Nowadays, they are a commodity good and often a bargain
03. Blackhat SEO Redirects to Malware and Rogue Software - Sampling an active blackhat SEO campaign out of the hundreds of thousands currently active online, releaved a large portfolio of domains serving Zlob variants by pitching them as fake codecs that the end user should download if they are to view the non existent adult content at the sites. Where's the OSINT mean? It's in the fact that the codecs and the fake security software phone back to UkrTeleGroup Ltd's network
04. Using Market Forces to Disrupt Botnets - With the current oversupply of malware infected hosts, and botnet masters embracing the services model for anything malicious, in this post I discussed the radical security approach of puchasing already infected malware hosts on a per country basis, disinfecting them and forcing them to update all the software on the infected PCs. Of course, on an opt-in basis. The possibility to directly provide incentives for botnet hunters to shut down whatever they come across to on a daily basis, and that's a lot of botnets, is also there
05. Who's Behind the GPcode Ransomware? - The title speaks for itself, the research with enough actionable intelligence gathered in the shortest timeframe possible is already proving accurate and highly valuable. How come? Stay tuned for more developments
06. ImageShack Typosquatted to Serve Malware - In a rare instance of a creative attack combining typosquatting in order to impersonate ImageShack and serve malware by redirecting users to an image file that is actually forwarding to the binary, I was recently tipped by the folks at TrendMicro who are also following this that the site is up and running again. Not for long
07. Fake YouTube Site Serving Flash Exploits - Next to using the usual set of exploits courtesy of a commodity web malware exploitation kit, this campaign was also using flash exploits. Even more interesting is the fact that the password stealer obtained was attempting to phone back to a misconfigured malware command and control interface, basically allowing you to assess the campaign from the eyes of the "campaigner"
08. Monetizing Web Site Defacements - Web site defacements are getting monetized just like SQL injections are in order to locally host a blackhat search engine optimization campaign on a vulnerable site with a high page rank. In this post I've assessed such monetization courtesy of a web site defacer at The Africa Middle Market Fund
09. Malicious Doorways Redirecting to Malware - Yet another large domains portfolio exposed though a malicious doorway redirecting to fake porn and video sites serving Zlob variants, tracking down the initial spamming of the malicious doorways across multiple vulnerable forums and guestbooks
10. The Zeus Crimeware Kit Vulnerable to Remotely Exploitable Flaw - When cyber criminals get advised to patch their vulnerable versons of the Zeus Crimeware Kit, you know there's a monoculture in the crimeware market. This flaw released publicly in May, 2008, not just allows others to hijack someone's ebanking botnet, but also, vendors and researchers to better assess a vulnerable Zeus command and control location
11. Fake Celebrity Video Sites Serving Malware - When templates for fake video and adult sites are just as available as they are now, anyone can take advantage of this cheap social engineering track that seems to work just fine. Compared to relying on blackhat search optimization to acquire traffic, some of the campaigns were SQL injected at vulnerable sites in order to drive traffic to them, next to several other tactics which when combined can result in a lot of people unknowingly visiting the sites
12. Phishing Campaign Spreading Across Facebook - An internal phishing campaign was circulating across Facebook, which got taken care of thanks to coordinated efforts with Facebook's security folks. There's also an indicating tha they are currently typosquatting other social networking sites like Hi5 for instance
13. Underground Multitasking in Action - As a firm believed in taking a random sample for a particular threat segment, this was once of these cases confirming the confidence I've built into anticipating upcoming tactics and strategies to be used
14. An Update to Photobucket's DNS Hijacking - Despite that Photobucket didn't oficially acknowledge the DNS hijacking, the hosting provider the NetDevilz hacking team used issued a statement. Ironically, the Turkish hacking group used the same provider weeks later to redirect ICANN and IANA's domains to Atspace.com
15. Fake Porn Sites Serving Malware - Among the largest domains portfolio of malware serving porn sites I've exposed in a while, all of them naturally remain active since they are hosted on a partition of RBN's diverse network. Visualizing a malicious doorway or the entire ecosystem provides a better understanding at how structured the ecosystems are
16. Backdoording Cyber Jihadist Ebooks for Surveillance Purposes - Despite that in this case we have a cyber jihadist backdoording his own released books, the international intelligence community next to law enforcement are known to have expressed interest in backdooring suspect's PCs, so why not SQL inject the cyber jihadist forums themselves?
17. Right Wing Israeli Hackers Deface Hamas's Site - When you read that Hamas's site is hacked, you ask yourself the following, do they even have a web site that's up the running? The answer to which would be the fact that even Hezbollah has been maintaining an Internet infrastructure since 1998
19. The Malicious ISPs You Rarely See in Any Report - Who's tolerating malicious activities on their network, and how is the RBN related to all this? Well, when combined, the tiny parts of these ISPs represent a tiny part of the Russian Business Network itself
10:00 Virus Top 20 for June 2008Summer vacation is in full swing, which means changes in the statistics for malicious programs in mail traffic are relatively small. >>>
00:00 Kill Switches and Remote ControlIt used to be that just the entertainment industries wanted to control your computers -- and televisions and iPods and everything else -- to ensure that you didn't violate any copyright rules. But now everyone else wants to get their hooks into your gear.
OnStar will soon include the ability for the police to shut off your engine remotely. Buses are getting the same capability, in case terrorists want to re-enact the movie Speed. The Pentagon wants a kill switch installed on airplanes, and is worried about potential enemies installing kill switches on their own equipment.
Microsoft is doing some of the most creative thinking along these lines, with something it's calling "Digital Manners Policies." According to its patent application, DMP-enabled devices would accept broadcast "orders" limiting capabilities. Cellphones could be remotely set to vibrate mode in restaurants and concert halls, and be turned off on airplanes and in hospitals. Cameras could be prohibited from taking pictures in locker rooms and museums, and recording equipment could be disabled in theaters. Professors finally could prevent students from texting one another during class.
The possibilities are endless, and very dangerous. Making this work involves building a nearly flawless hierarchical system of authority. That's a difficult security problem even in its simplest form. Distributing that system among a variety of different devices -- computers, phones, PDAs, cameras, recorders -- with different firmware and manufacturers, is even more difficult. Not to mention delegating different levels of authority to various agencies, enterprises, industries and individuals, and then enforcing the necessary safeguards.
Once we go down this path -- giving one device authority over other devices -- the security problems start piling up. Who has the authority to limit functionality of my devices, and how do they get that authority? What prevents them from abusing that power? Do I get the ability to override their limitations? In what circumstances, and how? Can they override my override?
How do we prevent this from being abused? Can a burglar, for example, enforce a "no photography" rule and prevent security cameras from working? Can the police enforce the same rule to avoid another Rodney King incident? Do the police get "superuser" devices that cannot be limited, and do they get "supercontroller" devices that can limit anything? How do we ensure that only they get them, and what do we do when the devices inevitably fall into the wrong hands?
It's comparatively easy to make this work in closed specialized systems -- OnStar, airplane avionics, military hardware -- but much more difficult in open-ended systems. If you think Microsoft's vision could possibly be securely designed, all you have to do is look at the dismal effectiveness of the various copy-protection and digital-rights-management systems we've seen over the years. That's a similar capabilities-enforcement mechanism, albeit simpler than these more general systems.
And that's the key to understanding this system. Don't be fooled by the scare stories of wireless devices on airplanes and in hospitals, or visions of a world where no one is yammering loudly on their cellphones in posh restaurants. This is really about media companies wanting to exert their control further over your electronics. They not only want to prevent you from surreptitiously recording movies and concerts, they want your new television to enforce good "manners" on your computer, and not allow it to record any programs. They want your iPod to politely refuse to copy music to a computer other than your own. They want to enforce their legislated definition of manners: to control what you do and when you do it, and to charge you repeatedly for the privilege whenever possible.
"Digital Manners Policies" is a marketing term. Let's call this what it really is: Selective Device Jamming. It's not polite, it's dangerous. It won't make anyone more secure -- or more polite.
