Domestic appliance manufacturer Whirlpool has come under fire for failing to clean up a malware infection on one of its sites, months after it was notified of a problem by UK anti-virus firm Sophos.

Sophos tried for months to clean-up its Kitchenaid.com website, without success, before going public on the problem on Friday. The kitchen utensil selling site remains infected with the Badsrc-C (AKA Asprox) strain of malware five months after a Sophos customer reported a problem, which the security firm forwarded to the white goods firm.

The malicious script points towards nowhere at present, so there isn’t an immediate risk. The problem is that this may change at any time, hence the need for remedial action that Whirlpool seems reluctant to take.

“I and several of my colleagues have been trying to talk to contacts at KitchenAid and Whirlpool to inform them of the issue and offer assistance. We have consistently hit brick walls,” reports senior Sophos threat analyst Paul Baccas.

Whirlpool’s lack of action is symptomatic of a wider problem. Reports of malware problems on websites are hard even for security firms to send to the right person, are often disregarded and sometimes met with indignation, Baccas writes.

The Asprox strain of malware still lingering on Kitchenaid.com’s website has been linked to phishing spam. SQL injection attacks on vulnerable website have been a preferred method for spreading malware.

Board.ie, the most popular forum in Ireland with millions of unique visitors each month, suffered a serious security breach yesterday. As a precaution, the website was taken offline and a password reset was triggered for all registered users.

“Today, Thursday 21 Jan 2010 at 11:20 GMT the Boards.ie database was attacked by a source external to Ireland. […] In this attack, part of the database which includes our members’ usernames, email addresses and obfuscated passwords was accessed. While our investigations indicate that individual user accounts are not in danger we have taken the step of changing all user passwords,” an official announcement reads.

The website administration has been remarkably opened about this incident and seems to treat it very responsibly. It immediately contacted the Gardai (Irish National Police) and the Data Protection Commissioner. No details regarding the specific attack method or origin have been released, as the investigation is in progress.

An independent security consultancy company has also been asked to advise regarding incident response procedure. “Like all large sites we are regularly the target for disruption and take continual actions to proactively protect your data. This particular attack was completely unprecedented despite our rigorous security measures and while we have no idea if this data will be used for any malicious reasons, we felt it vital to tell you this immediately,” the admins write.

The board.ie community website is built using the widely popular vBulletin forum software. Because of the security features implemented on the platform, user passwords were not stored in plain text inside the database. Even so, a decision to have them reset was taken as a precaution.

When the site will be restored, users will have to request new passwords manually. In order to prove their identity, they are required to have access to the e-mail address associated with the account. Admins are still working on an alternative method for cases where users can no longer access the e-mail that was used to register their account with.

The origins of the boards.ie forum date back to 1998, but the site has existed under the current name since 2000. It has over 220,000 registered members who communicate with each other on a variety of topics that touch on all aspects of life.

The University of Exeter in South West of England experienced serious problems with its computer network earlier this week due to a virus outbreak. Systems running Microsoft Windows Vista with Service Pack 2 seem to have been particularly affected by the unnamed malware.

The problems started on Monday when a computer virus was introduced onto the network. “Experience of dealing with data corrupting viruses elsewhere indicates that it is essential to shut down the network ASAP to avoid so many machines and files being corrupted that it takes weeks to recover. Therefore, although this is a PC rather than a network problem, we had to shut down the network to isolate the virus,” announced David Allen, the university’s registrar and deputy chief executive.

The exact name of the virus has not been disclosed, but ZDNet cites insider sources according to which, it exploits the vulnerability described in Microsoft’s MS09-050 Security Bulletin. “This is a completely new virus and we are the only organisation in the world to experience it. None of the mainstream virus software suppliers have seen this virus, and as such, there is no fix,” a leaked internal e-mail from the IT department allegedly reads.

Mr. Allen also pointed out that a security expert had been called on site to assist with the cleaning efforts. Apparently, this malware has only been detected on computers running Windows Vista and the specialized staff plans to check all such systems. This would suggest that the “virus” can spread from one computer to another, which would technically make it a computer worm.

“University campuses are, of course, complex beasts and the IT teams who secure them can have a tough job. The problem is compounded by having a massive userbase of students who may plug their own devices into the network, or may show little care for the security of a communal computer and put it at unnecessary risk,” notes Graham Cluley, senior technology consultant at antivirus vendor Sophos.

The network is slowly being brought back online, beginning with buildings that do not use Windows Vista computers. Several services such as Outlook Web Access and the MyExeter Web portal remain functional, but other network-dependent equipment like VoIP telephones or interactive teaching boards are unusable.

The University of Exeter has almost 16,000 students and three campuses, two in Exeter and one in Cornwall. The Cornwall campus is shared with the University College Falmouth and was isolated from the affected network immediately after the threat was discovered.

Network Solutions announced that several hundred websites hosted on its infrastructure fell victim in a mass defacement attack during the past several days. Preliminary findings suggest that a remote file inclusion technique was used to compromise several of the company’s Unix servers.

Network Solutions is one of the top five Internet domain name registrars, managing around 6,5 million domains as of January 2009. Apart from its successful domain registration business, the company also offers other services such as Web hosting, ecommerce or online marketing solutions.

The problems began for Network Solutions last weekend when several customers reported their websites being defaced by hacktivists. Most of the attacked websites had anti-Israel messages posted on their home page and displayed violent images.

At first, the Internet firm thought a vulnerability in a Web application shared by these websites might be the culprit. “We are running a scan to see if we can proactively determine if any hosting accounts are impacted. Proponents of malware and hacking commonly look for websites with vulnerabilities. These include weak passwords, third party applications that aren’t up to date or sometimes weakness could emanate from lack of updated anti-virus software on PCs,” Shashi Bellamkonda, the company’s director for social/new media strategy, wrote on Sunday.

However, it appears that these attacks were made possible by the configuration of the hosting servers themselves, which opened a remote file inclusion (RFI) weakness. Such vulnerabilities stem from improper validation of values being passed to the $_GET of $_POST variables under certain PHP configurations.

“Hackers were able to add a file displaying illegitimate content on top of the customer website content. This was an issue on multiple servers and unknown intruders were able to get through by using a file inclusion technique. There was no danger to any personally identifiable or secure information,” Mr. Bellamkonda announced yesterday in an update on the company’s blog.

Network Solutions is working with affected customers to restore their websites and is closely monitoring the threat. It has yet to decide if the best course of action is to make permanent changes to the configuration of its servers, a decision that might affect the functionality of existent websites.

Microsoft published an advisory today about a critical security vulnerability in all versions of Internet Explorer (apart from version 5). While all versions of Internet Explorer are affected, the risk for everyone running Internet Explorer 8 is lower since it has DEP (Data Execution Prevention) enabled by default.

According to McAfee, hackers who breached the defenses of Google, Adobe Systems and at least 32 other companies used this vulnerability to carry out at least some of the attacks.

The previously unknown flaw in the IE browser was probably just one of the vectors used in the attacks, McAfee CTO George Kurtz wrote in a blog post. Using a sophisticated spear-phishing campaign, the perpetrators included malicious links exploiting the bug in emails and instant messages sent to employees from at least three of the targeted companies.

Contrary to previous speculation, there was no evidence vulnerabilities in Adobe’s Reader or Acrobat applications were used in any of the attacks, Kurtz said. In its own statement, adobe concurred, saying researchers “have not been able to obtain any evidence to indicate that Adobe Reader or other Adobe technologies were used as the attack vector in this incident.”

Kurtz said his findings were based on malware samples taken from “three to five” of the targeted companies and he stressed that other zero days or exploits could have been used against other victims.

“In our investigation we discovered that one of the malware samples involved in this broad attack exploits a new, not publicly known vulnerability in Microsoft Internet Explorer,” Kurtz wrote. “Our investigation has shown that Internet explorer is vulnerable on all of Microsoft’s most recent operating system releases, including Windows 7.”

Shortly after the report, Microsoft confirmed the new IE vulnerability was “one of the vectors used in targeted and sophisticated attacks against Google and possibly other corporate networks.” A company statement said the attacks were carried out against version 6 of the widely used browser and suggested users protect themselves by enabling security features that have been added to successor versions.

McAfee’s report is the latest to shed light on one of the most significant cyberattacks in years. Google first disclosed the “highly sophisticated and targeted attack” on Tuesday, saying it originated in China and targeted its intellectual property. It added that 20 other companies suffered similar assaults, a number that independent researchers soon raised to 34. So far, only Google and Adobe have been identified as victims.

Yahoo, Symantec, Northrop Grumman and Dow Chemical have also been penetrated according to The Washington Post, citing unnamed “congressional and industry sources.”

The malware that McAfee researchers analyzed was sent to a highly select group of employees of a handful of companies that Kurtz declined to identify.

“This wasn’t something that got blasted to 300,000 people in a corporation,” Kurtz said in an interview with The Register. “It was really targeted at senior technology leaders that had access to core pieces of intellectual property, source code, et cetera.”

Kurtz has dubbed the attack “Aurora,” a reference to the filepath on the attacker’s machine that showed up in some of the malware code McAfee researchers analyzed. They believe that is the name the attackers gave to the operation. There was nothing in the binaries that indicated either way whether the code writers spoke Cantonese or Mandarin or were located in China.

The IE vulnerability stems from an invalid pointer reference that when exploited allows an attacker to execute malicious shell code on underlying machines. The malware caused exploited machines to download further malicious scripts that installed a backdoor. The machines then connected to command and control channels that were hosted on servers that resided in the US and Taiwan.

A security feature known as data execution prevention, which prevents data loaded into memory from being executed, will block the particular exploits McAfee has observed. But Kurtz warned the vulnerability exists in all versions of IE except for IE 5.01, service pack 4, and that it would be possible for attackers to work around the protection.

In an advisory, Microsoft recommended people use DEP, which by default is enabled in IE 8 but must be turned on in prior versions. The statement also advised users on Vista and later versions of Windows to run IE in protected mode. The advisory didn’t say when an update would be released that patches the vulnerability.

In a recent attack on the web server of the BerliOS (Berlin Open Source) open source platform intruders replaced the portal’s home page. The unknown attackers left a message accusing the BerliOS operators of not investing enough time in proper system maintenance – and in protection against attacks.

“Open source mediator” BerliOS, which is part of Fraunhofer Institute (FOKUS), hosts a number of developer projects on its systems. According to the injected message on the, now restored, home page, the attackers were also able to access the svn.berlios.de, download.berlios.de and example.sheep.berlios.de servers.

While the intruders said they didn’t manipulate any site content, they pointed out possible manipulations by others. According to the unknown hackers, BerliOS had already had secret visitors in 2005. The attackers said this was indicated by the presence of a developer.php.de.hacker file stored on the web server.

When asked by The H’s associates at heise Security, BerliOS confirmed the manipulation. The operators say that so far, apart from the traces of the intrusion, they have not found any sign of manipulated files. In a brief reply Jörg Schilling, BerliOS employee and developer of the cdrecord open source software said “Therefore, I currently don’t see a reason to issue a warning”. Schilling didn’t supply any details about the vulnerability the intruders exploited.

Google plans to curb its controversial practice of censoring search results in China after uncovering a “highly sophisticated and targeted attack” designed to steal information about human rights activists from its Gmail service and at least 20 other large companies.

The attack that hit Google in mid-December originated in China and was aimed at accessing the Gmail accounts of human rights activists. Although only two email accounts appear to have been breached, “accounts of dozens of US-, China- and Europe-based Gmail users who are advocates of human rights in China” have been routinely breached, most likely as a result of phishing or malware attacks, the company said Tuesday.

The discovery came as Google uncovered similar attacks on at least 20 other companies in the financial, technology, media, and chemical industries. In light of the revelations, Google said it is considering shuttering its Chinese operations altogether.

“These attacks and the surveillance they have uncovered - combined with the attempts over the past year to further limit free speech on the web - have led us to conclude that we should review the feasibility of our business operations in China,” Google’s chief legal officer David Drummond wrote. “We have decided we are no longer willing to continue censoring our results on Google.cn, and so over the next few weeks we will be discussing with the Chinese government the basis on which we could operate an unfiltered search engine within the law, if at all.”

Drummond said Google has already used the investigation findings to introduce security improvements. The company is also in the process of sharing its findings with law enforcement authorities and the other targeted sites.

“We have taken the unusual step of sharing information about these attacks with a broad audience not just because of the security and human rights implications of what we have unearthed, but also because this information goes to the heart of a much bigger global debate about freedom of speech,” Drummond wrote.

He didn’t provide details about the two breached Gmail accounts except to say that “activity was limited to account information (such as the date the account was created) and subject line, rather than the content of emails themselves.” The names of the 20 large companies were also omitted.

Google, whose corporate credo is “Don’t be evil,” entered the Chinese market in 2006 with the promise to censor search results that were objectionable to the country’s government.

Hackers have stolen the login credentials for more than 8,300 customers of small New York bank after breaching its security and accessing a server that hosted its online banking system.

The intrusion at Suffolk County National Bank happened over a six-day period that started on November 18, according to a release issued Monday. It was discovered on December 24 during an internal security review. In all, credentials 8,378 online accounts were pilfered, a number that represents less than 10 percent of SCNB’s total

“Although the intrusion was limited in duration and scope, SCNB immediately isolated and rebuilt the compromised server and took other measures to ensure the security of data on the server,” the bank, located about an hour east of New York City, stated. “To date, SCNB has found no evidence of any unauthorized access to online banking accounts, nor received any reports of unusual activity or reports of financial loss to its customers.”

The breach represents a variation on more traditional types of attacks on online banking. Cyber crooks typically target customers by surreptitiously planting malware on their computers that log their user name and password. The FBI estimates that small and medium-sized businesses alone have reached $100m.

By contrast, accessing a server that storing online credentials for tens of thousands of customers isn’t the kind of intrusion one hears about every day. Best security practices are clear that passwords should never be stored on servers unless they are encrypted.

The bank began notifying affected customers on Monday evening using first-class mail. The two-week delay “was necessary for making a lot of arrangements so we could come out with an absolutely conclusive statement about what happened,” said Douglas Ian Shaw, the bank’s corporate secretary. Retail customers whose details were lifted will be given two years worth of credit monitoring services at SCNB’s expense.

In the fourth quarter, the bank budgeted $351,000, or about 4 cents per share, to account for expenses related to the intrusion. Additional expenses may be incurred.

The same group that used a DNS attack to hijack Twitter last month has defaced the home page of Chinese search engine Baidu.

Baidu, formed in 2000, is China’s number one search engine, dominating the home market for online searches - partly because it had a six year head start over Google. As a result of its huge popularity, it’s no wonder that from time to time hackers might try and take advantage of the site, just as top websites can be in the frame for attack in the West.

Surfers visiting Baidu site on Monday night were confronted by the message “This site has been hacked by Iranian Cyber Army”, together with an image of the Iranian flag. Early speculation suggests the attack involved changing Baidu’s DNS records rather than a direct attack on the site itself, but this remains unconfirmed.

The attack might have been used to point the millions of Chinese users who use Baidu every day towards a site that took advantage of browser exploits to infect computer users with malware. So it’s perhaps fortunate that the Baidu hack involved only political graffiti.

By Tuesday morning, Baidu’s site had been cleaned up.

A Romanian grey hat hacker has disclosed an SQL inject (SQLi) vulnerability on a website belonging to the United States Army, which leads to full database compromise. The website, called Army Housing OneStop, is used to provide information about military housing facilities to soldiers. The website has been taken offline.

The Army Housing OneStop (AHOS) is “the official Army website for soldiers who need information about Military Family Housing (MFH), Unaccompanied Personnel Housing (UPH) and/or Community (Off-Post) Housing. It includes both comprehensive and quick-reference information for Army installations worldwide.”

A self-confessed security enthusiast, who goes by the online handle of TinKode, documented a proof-of-concept attack against the onestop.army.mil on his personal blog. The published screenshots reveal that the Web server runs on Microsoft Windows 2003 with Service Pack 2 and the database engine used to power the ASP website is Microsoft SQL Server 2000:

#Version: Microsoft SQL Server 2000 - 8.00.2282 (Intel X86) Dec 30 2008 02:22:41 Copyright (c) 1988-2003 Microsoft Corporation Enterprise Edition on Windows NT 5.2 (Build 3790: Service Pack 2
#User: Dynatouch
#Database: AHOS
#Host Name: AHSGSVDAHQIT130

The AHOS website seems to have been developed by DynaTouch Corporation, a third-party government contractor that provides software and hardware solutions to create “self-service kiosk systems.” The company’s client portfolio includes a long list of local and federal government organizations.

There are a number of 76 databases on the server, but TinKode focused his attention on the one called “AHOS.” There are various tables in this database containing general website configuration information, but two in particular stand out as they are called “mgr_login” and “mgr_login_passwords.”

Upon investigating the latter, the hacker stumbled upon passwords stored in plain text, a major security oversight. Storing cryptographic hashes instead of the actual password strings has been a common practice in Web application programming for years now. Furthermore, if for convenience the hashes are generated with a weak algorithm, a technique known as “salting” can be employed to make them nearly impossible to crack.

In a time when even the most amateur programmers follow such security practices, the fact that many business or government websites do not boggles one’s mind. Additionally, the administrative account is called “Dynatouch” – who would have guessed that? – and its password is “AHOS” – yes, really.
