Google Gmail Hacked

Google Gmail Hacked

An attack from China has affected hundreds of users, including senior U.S. government officials, Chinese political activists, officials in several Asian countries such as South Korea, military personnel, and journalists.

Google has detected a campaign to gather Gmail account credentials that appears to originate from Jinan, China, and is warning users to take a few minutes to review their security settings.

Eric Grosse, engineering director for Google’s security team, said in a blog post that hundreds of users have been affected, including senor U.S. government officials, Chinese political activists, officials in several Asian countries such as South Korea, military personnel, and journalists.

“The goal of this effort seems to have been to monitor the contents of these users’ emails, with the perpetrators apparently using stolen passwords to change peoples’ forwarding and delegation settings,” Grosse said.

By changing these settings, which are only evident through the appropriate Gmail Settings tab page, the attackers could generate copies of incoming and outgoing email that would be forwarded without the account holder’s knowledge.

Google declined to provide further details or information about those it believes may be behind the attack.

In January 2010, Google reported that it had uncovered “a highly sophisticated and targeted attack on our corporate infrastructure originating from China.” Google said at the time that it had reason to believe that one of the main goals of the attackers was to compromise the Gmail accounts of Chinese human rights activists.

In that respect, the attack was not very successful: While Google acknowledged that the attackers had stolen unspecified intellectual property, it stressed that only two Gmail accounts appeared to have been accessed.

Jinan, capital of Shandong Province in Eastern China, happens to be the location of the Lanxiang Vocational School, one of the two Chinese schools linked to the 2010 attack against Google.

An October 2009 report on Chinese cyber espionage prepared by defense contractor Northrop Grumman said that the Chinese military maintains at least six technical reconnaissance bureaus for gathering cyber intelligence in the Lanzhou, Jinan, Chengdu, Guangzhou, and Beijing military regions.

The current attack differs from the 2010 attack in that it doesn’t involve a vulnerability in Google’s infrastructure; it is simply a phishing campaign to dupe users into revealing their Gmail login credentials.


Google said that it detected the phishing campaign through its cloud-based security and abuse detection systems, through the reports from users, and through a report published in February on the Contagio blog, a collection of malware samples and threat analysis. The company said it has notified victims and the relevant government authorities.

Google is advising Gmail users to consider steps to improve the security of their accounts. The company recommends using two-factor verification, using a strong password, only entering account information at the proper Google domain, checking Gmail settings for unknown forwarding addresses or unauthorized account delegation, watching for suspicious account activity warnings, using Google Chrome, and reviewing security education materials available online.

Google Android Security

Google Android Security

Google is rolling out a security patch for Android that fixes a vulnerability reported to have affected 99 per cent of users.

The patch fixes an issue flagged by German security experts that could allow hackers to look at personal information in the Google calendar and contacts apps.

The University of Ulm researchers said that in Android 2.3.3 and earlier these apps transmitted unencrypted information to retrieve an authentication token, or Authtoken, from Google. This left an opening where criminals could steal the token through WiFi snooping.

Once a hacker had one of these Authtokens, they could use it for several days, accessing your private information and potentially impersonating an individual smartphone. In Android 2.3.4 this flaw is fixed, but it was mentioned that 99 per cent of Android users were still using versions 2.3.3 and earlier, which meant they were all at risk.

But now Google is updating all of the endangered handsets with a silent server-side patch that won’t require any action by Android users, forcing servers to use an encrypted HTTPS connection when syncing with a handset.

A Google spokesperson said, “We’re starting to roll out a fix which addresses a potential security flaw that could, under certain circumstances, allow a third party access to data available in calendar and contacts. This fix requires no action from users and will roll out globally over the next few days.”

Sophos security consultant Graham Cluley praised Google’s actions but added, “Concerns still remain as to how easy it would be to fix a serious security vulnerability on the Android devices themselves, given that Google is so reliant on manufacturers and carriers to push out OS updates.”

Infected Search?

Infected Search?

Antivirus company Avast alleges that ads served by companies such as Google, Yahoo! and Fox, and published on websites such as the New York Times and TechCrunch, have included bad software that could infect your computer.

Users don’t even have to click the ads to be affected. Their browser gets infected just from loading the ads. CNet has the story.

The report allegs these companies’ ad platforms include exploits that allow malicious hackers to run a JavaScript exploit called JS:Prontexi.

Prontexi is a Trojan horse targeting Windows machines that looks for further vulnerabilities in software such as Adobe’s Reader and Acrobat, Java, QuickTime and Flash. It pops up fake antivirus warnings to trick you into installing further malware. The malware started spreading in late December. Since then, Avast has found it has infected more than 2.6 million computers. Almost 530,000 of those were from Yield Manager and more than 16,300 from DoubleClick.

The worst affected are Yahoo!’s Yield Manager, Fox Audience Network’s Firmserve.com and Google’s DoubleClick. Together, these networks serve over 50% of all internet ads. DoubleClick has been the least affected and Google has been the fastest at tackling the problem, according to CNet and Avast.

A Yahoo representative confirmed the report and said it was investigating the situation, but didn’t provide much information. “We have identified the creatives in question and are working to make sure they been deactivated in our system,” the company said in a statement.

“Yahoo is deeply committed to providing a high-quality experience for users, advertisers, and publishers. We expect our members to support and abide by our standards and guidelines around acceptable ad content and behavior,” the statement said. “On the rare occasion that an ad is served that is in conflict with our expectations and guidelines we take action to remove it as quickly as possible.”

A Google spokesman said the company had discovered malware in ads from DoubleClick on its own and halted them. “In this case, we stopped several of the ads in question on the same day, independent of this report,” he said.

Google and Mozilla Fix Browser Flaws

Google and Mozilla Fix Browser Flaws

Google and Mozilla have released new versions of their browsers, plugging plenty of security holes along the way.

Hundreds of bugs have been fixed in the Google Chrome update, after the company said it would be releasing a “new stable version” of the browser every six weeks.

So far Google has followed through with its promise and introduced the patches along with a new HTML5 parser and file API, among other features.

“Also, if you choose to block sites from setting any data in your browser’s content settings for cookies, you can now use a new dialog for managing blocked cookies in bulk,” noted Jeff Chang, product manager for Google Chrome, in a blog.

Google recently launched a security advice page offering some tips on how users can protect themselves from hackers.

Mozilla, meanwhile, has made Firefox versions 3.6.11 and 3.5.14 available for download, patching nine vulnerabilities along the way.

Five of the flaws were ranked as critical, meaning they could be exploited “to run attacker code and install software, requiring no user interaction beyond normal browsing,” Mozilla explained.

“As always, we recommend that users keep up to date with the latest stability and support versions of Firefox, and encourage all our users to upgrade to the very latest version, Firefox 3.6.11,” advised Firefox release manager Christian Legnitto.

Fake Anti-Virus on the Rise

Google researchers have uncovered a significant spike in fake anti-virus software circulating the web.

“Once it is installed on the user system, it’s difficult to uninstall, you can’t run Windows updates anymore or install other antivirus products.”

There has been a rise in the prevalence of fake antivirus (AV) software, which now accounts for 15 per cent of all malware on the web, a report by Google researchers has shown.

The team claimed that fake AV software is responsible for half of all malware delivered through online adverts, representing a 500 per cent rise in a year.

In their analysis of 240 million web pages collected by Google’s malware detection infrastructure over 13 months, the researchers found that more than 11,000 domains were involved in distributing fake AV.

Back in January last year, the team identified only 93 unique fake AV domains, but this rose to 587 in the final week of January 2010.

“As users are becoming increasingly aware of the need to secure their computers, attackers have been leveraging this awareness by employing social engineering techniques to distribute fake AV software,” the researchers said.

“Fake AV attacks continue to persist, demanding increased awareness and broader response from the research community at large.”
