Ubisoft has confirmed its rights management servers were hit by a fierce DDoS attack over the weekend that left some customers unable to play its games for much of Sunday.

The attack is an apparent protest at controversial new DRM controls by the video game publisher which mean customers have to be online in order to play its latest PC games such as Assassin’s Creed II and Silent Hunter 5.

The introduction of so-called Online Services Platform technology last month means it’s impossible to play a game without an internet connection or save progress while playing a game if an internet connection is lost. The controls, designed to combat piracy, have sparked much negative comment in the gamer community and apparently inspired action by hacktivists over the weekend that curtailed gameplay for some.

“Apologies to anyone who couldn’t play ACII or SH5 yesterday,” Ubisoft said in a post. to its official Twitter account on Monday. “Servers were attacked which limited service from 2:30pm to 9pm Paris time.”

“95 per cent of players were not affected, but a small group of players attempting to open a game session did receive denial of service errors,” it added in a later update.

Meanwhile Ubisoft’s much criticised controls have been broken by software hackers. A hacker group called Skid-Row managed to bypass DRM restrictions on Silent Hunter 5 less than 24 hours after the game was published.

Vodafone has been blamed for shipping Mariposa botnet malware and other nasties on a HTC Magic Android smartphones it supplied.

The mobile phone giant’s Spanish arm supplied an HTC Magic smartphone preloaded with malware that attempted to establish a backdoor for stealing information on connected PCs during the synchronisation process. Vodafone acknowledged the problem but said that the incident was an isolated and local problem, which came to light because the customer affected works for Spanish anti-virus firm Panda Security.

The extra code was a strain of the Mariposa bot client that attempted to connect to systems not associated with the recent arrests of three suspected botmasters in Spain, according to an analysis of the attack by Panda Security researcher Pedro Bustamante.

“A quick analysis of the malware reveals that it is in fact a Mariposa bot client,” Bustamante explained. “This one, unlike the one announced last week which was run by Spanish hacker group ‘DDP Team’, is run by some guy named ‘tnls’ as the botnet-control mechanism shows.

“Once infected you can see the malware ‘phoning home’ to receive further instructions, probably to steal all of the user’s credentials and send them to the malware writer,” he added.

The same mobile phone was also infected by Confiker and a Lineage password-stealing code, according to Panda. The incident came to light because the infected phone was sold to one of Bustamante’s colleagues in Spain.

In a statement, Vodafone said the problem, which it is investigating, was isolated.

Vodafone takes the security and privacy of its customers extremely seriously and launched an immediate investigation into this incident

Following extensive Quality Assurance testing on HTC Magic handsets in several of our operating companies, early indications are that this was an isolated local incident

Vodafone keeps its security processes under constant review as new threats arise, and we will take all appropriate actions to safeguard our customers’ privacy.

Incidents where computing devices come preloaded with malware are far from unprecedented. Normally problems arise when computers used in manufacturing production lines are themselves infected.

A Trojan backdoor found its way into Energizer Duo USB battery charger software downloads.

Malware bundled in a charger-monitoring software download package opens up a back door on compromised Windows PCs. The contaminated file is automatically downloaded from the manfacturer’s website during the installation process, not bundled with an installation CD.

Symantec warns that a file called “Arucer.dll”, which it identifies as Trojan-Arugizer, that is installed on compromised systems is capable of all manner of mischief. This includes sending files to the remote attacker or downloading other strains of malware, as instructed via commands on a back channel controlled by hackers.

It’s unclear how long the potentially malicious file has been offered up for public download or how many have been infected, as a write-up on the threat by Symantec explains:

We were interested in finding out how long this file had been available to the public. The compile time for the file is May 10, 2007. It is impossible to say for sure that this Trojan has always been in this software, but from our initial inspection it appears so. We also suspected that the entire file may have been inserted into the package without the creator’s knowledge, but upon closer inspection we discovered the DLL checks for the USB device.

In a statement, Energizer acknowledged the problem and discontinued sale of the affected device, the Duo Charger (Model CHUSB). The battery maker has also launched an investigation into how backdoor functionality found its way into its software.

Energizer has discontinued sale of this product and has removed the site to download the software. In addition, the company is directing consumers that downloaded the Windows version of the software to uninstall or otherwise remove the software from your computer. This will eliminate the vulnerability. In addition CERT and Energizer recommend that users remove a file that may remain after the software has been removed. The file name is Arucer.dll, which can be found in the Window system32 directory.

Energizer is currently working with both CERT and U.S. government officials to understand how the code was inserted in the software. Additional technical information can be found at http://www.kb.cert.org/vuls/id/154421.

Catalogue firm Argos has been criticised for an email security breach that exposed customers’ credit card details and CCV security numbers. The breach was discovered by UK Argos customer Tony Graham and first reported by PC Pro. Graham’s card details were recently fraudulently misused, but this incident has not been linked to the Argos email slip-up.

The exposure came to light after an Argos customer who checked his order confirmation email found that his credit card number and security code was buried in the HTML source of the message. The slip-up meant that any miscreants who intercepted email confirmation messages from Argos would be able to harvest plastic card payment details - if they spotted where the numbers were stashed.

It’s unclear how long the exposure problem lasted, or how many Argos customers were affected.

In a statement, Argos said it had already corrected the fault and was working with privacy watchdogs at the Information Commissioner’s Office in dealing with the fallout from the breach.

Argos takes the security of its customers’ data extremely seriously, is fully aware of the requirements of the Data Protection Act and has taken remedial action in relation to this matter.

We are in contact with the Information Commissioner’s Office. We have made them aware of our approach to customer communications and will continue to work closely with them to ensure we are taking all appropriate actions.

Ed Rowley, product manager EMEA at content security firm M86 Security, said the whole incident might easily have been prevented. “It is incomprehensible that this credit card data was sent out in an unencrypted format - even if the sensitive information was not visible in the main body it should have been protected from being sent out,” he said.

“A good email content filtering product could have enforced encryption or blocked this data from being sent out at all by Argos, using standard or default email security rules.

“This case highlights the need to filter both inbound and outbound email in order to guard against malware coming in but also to block sensitive information from leaking out. It’s astonishing that larger companies are not using these well established security tools and procedures.”

A popular Twitter service called Twitter Grader was hacked yesterday causing thousands of unauthorized tweets to be posted from the accounts of its users. Twitter Grader, which is normally available from grader.com along with other free grading applications, allows Twitter users to see how influential they are on the micro-blogging platform. The service is developed by an Internet marketing company called HubSpot.

The company’s founder and CTO, Dharmesh Shah, was completely taken by surprise yesterday when Twitter Grader users, including himself, started posting a strange message on their feeds. The unauthorized tweets contained a link to a 2006 video of Biz Stone promoting the micro-blogging platform.

Rik Ferguson, solutions architect at antivirus vendor Trend Micro, analyzed the message and concluded that, “The link that has been endlessly tweeted by grader users does not appear to host any malicious content.” The researcher also launched a possible explanation for the attack. “The domain name of the destination site [seonix.org] however might give us a clue to the motivation behind the attack. Seonix presumably refers to Search Engine Optimisation and perhaps that is the real purpose of this attack,” he wrote.

Access to the entire grader.com domain has been temporarily suspended until the issue is addressed and all applications are moved to more secure servers. The company also stresses that customers of its commercial services have not been affected, as these are hosted on a different infrastructure. Additionally, the usernames and passwords of Twitter users have not been compromised, because the Twitter Grader service used OAuth, a technology that doesn’t require login credentials.

The responses to the official blog post about the attack are overwhelmingly favorable, commending the company for its openness and seriousness in handling the incident. “Ladies and gents, is an object lesson in how to deal with an event like this. Much respect to HubSpot,” Rik Ferguson wrote, while an executive officer with a different company noted that, “How you handled it […] should be a lesson (case study?) for others.”

Security researchers warn that a significant number of WordPress websites have been compromised recently as part of what looks to be a money-generating affiliate scheme. The header.php template files are being injected with obfuscated JavaScript code.

“Late last week, I noticed something of a surge in reports of a particular threat: hoards of legitimate pages were being injected with a malicious JavaScript, pro-actively blocked as Mal/ObfJS-H. Thus far, the common link between the affected sites appears to be Wordpress. One user report suggests that the malicious script is being added to the header.php template script used by Wordpress,” Fraser Howard, principal virus researcher at Sophos, writes on the company’s blog.

The obfuscated script is inserted right after the tag and its purpose is to load additional content via an IFrame and to pass visitors through a series of silent redirects. One of these 302 redirects pass the affiliate account of the attacker to a remote script, probably for remuneration purposes.

According to Mr. Howard’s analysis, a cookie for a domain name rich-traffic.com is set in the visitors’ browsers, this site being a Russian affiliate network allowing users to sell or to buy IFrame traffic. “We sell only high quality iframe traffic for your various needs!” is written on the main page. Apparently, this offer refers to huge amounts of unique visitors spread across a wide variety of countries.

The issue of header.php files being modified without authorization has also been discussed in the support forums over at wordpress.org, with users suggesting that compromised FTP accounts might be the cause. This is consistent with the Sophos researcher’s conclusion, who writes that, “In this particular attack however, an out of date Wordpress installation does not appear to be the root cause – many of the sites I checked, appear to be running the latest available version (2.9.1 at time of writing).”

It is worth noting that TechCrunch, one of the most popular technology blogs on the Internet, has recently faced several attacks, which resulted in its home page being altered. At least in one particular attack, the header.php file was modified to include a rogue message.

Two Firefox add-ons available for months on Mozilla’s website infected users with malware that stole passwords and opened a backdoor on Windows machines, the open-source browser maker has confirmed.

The add-ons, available on an experimental section of Mozilla’s official add-on download site carried trojans that have been detected since 2008 by commercial anti-virus products. And yet they weren’t removed until late January and earlier this week because a scanning tool used to vet add-ons during upload failed to catch the malicious files.

“If a user installs one of these infected add-ons, the trojan would be executed when Firefox starts and the host computer would be infected by the trojan,” a note on Mozilla’s add-on blog stated. “Uninstalling these add-ons does not remove the trojan from a user’s system.”

Instead, infected users will need to thoroughly scan their machines with an anti-virus program. Or better yet, use multiple scanners, or simply reinstall the operating system to be on the safe side.

This isn’t the first time Mozilla has served malware-laced add-ons to its loyal base of users. In May 2008, a Vietnamese language pack for Firefox 2 contained a viral infection that resulted in users seeing unwanted ads. The add-on was downloaded almost 17,000 times before it was pulled.

In the most recent case, version 4 of the Sothink Web Video Downloader add-on installed a password sniffer dubbed Win32.LdPinch.gen and was downloaded about 4,000 times between February 2008 and May 2008. A separate add-on called Master Filer was laced with a backdoor trojan known as Win32.Bifrose that was downloaded 600 times between September 2009 and January of this year.

Mozilla removed Master Filer on January 25 and nixed Sothink on Tuesday.

The blog post said Mozilla added two new scanners to its validation chain. It was this change that allowed the organization to detect version 4 of the Sothink Web Video Downloader.

Versions greater the 4.0 of the video downloader add-on were not infected, Mozilla’s blog post stated. Both infections affected only Windows users of the open-source browser.

Over thirty websites of various Representatives and House Committees fell victim to mass defacement yesterday. The incident occurred shortly after President Obama gave his State of the Union address.

The attack seems to be politically motivated as it contained an offensive anti-Obama message. All affected websites are from within the house.gov domain and most of them served House Representatives. However, a few, such as gop.cha.house.gov, republicans.financialservices.house.gov, republicans.oversight.house.gov or resourcescommittee.house.gov, correspond to House committees.

According to Web defacement archive Zone-H, the Red Eye Crew is a prominent hacking group responsible for more than 45,000 defacements in 2009 alone. Around 2,000 of the affected websites are listed as special, meaning they belong to governments, military organizations or important corporations.

Determining a specific point of entry for these attacks without any insider knowledge is hard. However, security researchers from Praetorian Security Group determined that all compromised websites use the Joomla content management system. “But not all of the Joomla CMS web sites [on the same server] are affected. This might indicate that it is a Joomla component that is to blame, however that is just speculation,” they write.

It is worth noting that a significant number of websites within the house.gov domain were defaced last August by a different group. At the time, there was information to suggest that the compromise was the result of default passwords that were left unchanged.

“Unfortunately we won’t know that until someone who manages house.gov provides some details. Server access seems unlikely, because while the sites we checked are hosted on dcserver1.house.gov, not every site hosted on that server is defaced (example congressman Joe Sestak’s web site was fine). The sites are not redirecting anywhere,” the Praetorian Security Group experts conclude.

Popular technology site TechCrunch was hit by hackers late on Monday, leaving the site temporarily unavailable.

A notice on TechCrunch.com’s front page on Tuesday morning explains that “TechCrunch.com was compromised by a security exploit”. Access to the site’s story archive has been suspended leaving a two para notice on the hack as the only content visible on the site.

Hackers defaced the front page of the site with a message (recorded by Mikko Hypponen of F-Secure) apparently abusing site admins and including a link to a pornographic content and warez linking website.

The problems began for TechCrunch at around 10:30 pm PST on Monday when unknown hackers modified its home page to only display the word “hi.” The page was later changed to read “We’ll be back shortly,” suggesting that webmasters regained control of the website.

After a while, the site was hacked again and a link called “rapidshare downloads” appeared on the home page. The link actually pointed to DupeDB, a known warez website and was subsequently replaced by a “We’ll be back soon” message.

Hackers took over TechCrunch for a third time and left one offensive message accompanied by a link to the illegal content distribution site mentioned before. A final message from staff after this attack was also repelled, saying “Earlier tonight techcrunch.com was compromised by a security exploit. We’re working to identify the exploit and will bring the site back online shortly.”

Specific technical details regarding the incident are lacking, but a DNS hijacking attack similar to those experienced by Twitter and Baidu is out of the question. According to some sources cited by Praetorian Prefect, TechCrunch was using WordPress 2.8.4 at the time of the incident and 2.9.1 after. This apparent platform upgrade suggests that a WordPress vulnerability might have been exploited.

This defacement was removed by site admins who are in the process of identifying the exploit involved in the hack, securing systems, and bringing TechCrunch back online.

The motives or perpetrators of the attack remain unclear but the timing - a day before Apple’s much anticipated iTab launch in San Francisco - could hardly be worse.

TechCrunch returned to business by Tuesday lunchtime. The site has published a story on the attack, which is still under investigation. Hackers redirected traffic as well as leaving a defacement, TechCrunch explains.

Update (Jan. 27): TechCrunch has been hit by potty-mouth hackers for the second time in 24 hours. The second hack features a foul-mouth rant aimed against site founder Michael Arrington. It also includes a link to the same online smut and warez-peddling Torrents site “promoted” via the previous attack.

Ladbrokes is investigating the loss of thousands of customer details from one of its databases, but is reassuring gamblers that the information did not include bank details or passwords.

The Mail on Sunday was approached by an Australian man named Daniel who claimed to have access to Ladbrokes’ database of 4.5 million customers. Daniel gave the paper 10,000 customer files to show he was serious.

The man, who claimed to represent a Melbourne-based firm, said he had worked for Ladbrokes as a security consultant two years before. He said he’d been given the information by a relatively junior member of staff.

Ladbrokes said passing on the information was a criminal offense and it was working with police and the Information Commissioner’s Office to identify the culprit.

Ladbrokes said: “We are in the process of contacting the limited number of customers affected by this incident to apologise and to reassure them that the data in question does not include passwords to access customer accounts or any customer banking details.”

The Information Commissioner’s Office thanked the paper for bringing the breach to its attention. The ICO said the story showed the need for prison sentences for those convicted of trading in private data.
