Groupon India Subsidiary Leaks 300,000 Plain Text User Passwords

Keep on Guard!


Oh look! Another data-leak, this was was pretty bad as it contained plain-text passwords (who on earth doesn’t hash their passwords in the DB in 2011?!).

Anyway this time it was a Groupon subsidary – Sosata.com which managed to leak the e-mail addresses and plain-text passwords for 300,000 users AND on top of that, Google managed to index it.

The original story was published here:

Groupon leaks entire Indian user database

The leak was discovered by Australian security consultant Daniel Grzelak.

Groupon subsidiary Sosasta.com accidentally published a database containing the email addresses and clear-text passwords of 300,000 users and the cache was indexed by Google.

The trove of personal data was discovered by Australian security consultant Daniel Grzelak as he plugged a handful of query terms into the search engine, he said Tuesday. He contacted Patrick Gray with security blog Risky Biz, which reported that the SQL database contained the details for 300,000 Sosasta account holders.

A Groupon spokesman confirmed that the digital coupon distributor “was alerted to a security issue” on Thursday night and corrected the problem immediately. The issue was limited to Sosasta, which uses its own servers and network and isn’t connected to Groupon’s systems in other countries.

“We have begun notifying our subscribers and advising them to change their Sosasta passwords as soon as possible,” the spokesman said in a statement. “We will keep our Indian subscribers fully informed as we learn more.”

At least this time it seems like someone messed up rather than a hack by LulzSec or Anonymous. And it’s good to see an organization react quickly and responsibly to such an information disclosure, this is sadly a rather rare attribute.

The issue was limited to Sosata and did not effect any Groupon sites in other countries. Sosata users have been notified to change their passwords in the system, and I hope for their sakes not too much password re-use is going on.

I still don’t see the fact that the passwords were un-hashed being addressed anywhere though, doesn’t that concern anyone other than me?


At time of writing, there was no advisory on either the Groupon or Sosasta websites, although Sosasta’s Facebook page contained a notice that came in the form of a JPG image that couldn’t easily be indexed by Google or other search engines. Ah the irony.

According to Risky Biz, Grzelak found the massive cache as he was looking for additions to shouldichangemypassword.com, a side project that indexes email addresses included in more than a dozen high-profile privacy breaches carried out by LulzSec and other hacking groups. The query that hit pay dirt included the terms “filetype:sql” “password” and “gmail.”

“I started scrolling, and scrolling and I couldn’t get to the bottom of the file,” Grzelak told Risky Biz. “Then I realised how big it actually was.”

The Groupon statement didn’t say why passwords weren’t encrypted or why such a sensitive file was publicly available.

The snafu is the latest to expose the folly of using the same password on more than one site, a practice still followed by a shockingly high number of people. If you’re one of them, you ought to consider using a password-management program such as Password Safe or KeePass.

For developers – http auth/password protected directories are good! Hashing passwords is good! Leaking sensitive info is BAD!

Sincerely I doubt anyone reading this site re-uses simplistic passwords for their online accounts – but just in case you do – or know anyone that does – I do recommend using Password Safe or KeePass anyway, keep that shizzle secure yo!

Anyway, I wonder if anyone is going to sue over this?

Metasploitable – Test Your Metasploit Against A Vulnerable Host

Outsmart Malicious Hackers


Ok so you’ve got Metasploit loaded up, you’ve read the Metasploit Tutorials & Watched the Videos – but you’ve still got no idea what to do next and don’t have anything to test against.

It’s not exactly new, but I guess a lot of people still don’t know about it. Basically if you don’t know what to do next, this is where Metasploitable comes in! One of the questions that the Metasploit developers often hear is “What systems can I use to test against?” Based on this, they thought it would be a good idea throw together an exploitable VM that you can use for testing purposes.

Metasploitable is an Ubuntu 8.04 server install on a VMWare 6.5 image. A number of vulnerable packages are included, including an install of tomcat 5.5 (with weak credentials), distcc, tikiwiki, twiki, and an older MySQL.

You can use most VMware products to run it, and you’ll want to make sure it’s configured for Host-only networking unless it’s in your lab – no need to throw another vulnerable machine on the corporate network. It’s configured in non-persistent-disk mode, so you can simply reset it if you accidentally ‘rm -rf’ it.

There are various other similar setups you can test out your hacking kung-fu on like:

Hackers Exploiting Latest Adobe Flash Bug On Large Scale

Outsmart Malicious Hackers


It’s very out of character for Adobe – but they’ve actually released two out of band patches in the last week or so.

They’ve had to patch 4 times in the past 2 months – that’s a total of 6 times in 2011 so far – with 5 out of those 6 being for critical bugs.

It seems like Flash has become a major target for hackers in the past 6 months or so, despite the fact that Adobe has worked with Google to sandbox Flash in the Chrome browser.

Hackers are aggressively exploiting a just-patched Flash vulnerability, serving attack code “on a fairly large scale” from compromised sites as well as from their own malicious domains, a security researcher said Friday. The attacks exploit the critical Flash Player bug that Adobe patched June 14 with its second “out-of-band,” or emergency update, in nine days.

“CVE-2011-2110 is being exploited in the wild on a fairly large scale,” said Steven Adair, a researcher with the Shadowserver Foundation, a volunteer-run group that tracks vulnerabilities and botnets. “In particular this exploit is showing up as a drive-by in several legitimate websites, including those belonging to various NGOs [non-government organizations], aerospace companies, a Korean news site, an Indian government Web site, and a Taiwanese university.”

CVE-2011-2110 is the identifier for the Flash vulnerability assigned by the Common Vulnerabilities and Exposures database. Attackers are also using the exploit in “spear phishing” attacks aimed at specific individuals, said Adair on the Shadowserver site. Adair called the attacks “nasty” because the exploit “happens seamlessly in the background,” giving victims no clue that their systems have been compromised.

The CVE ID for this vulnerability is – CVE-2011-2110 with the NVD listing stating:

Adobe Flash Player before 10.3.181.26 on Windows, Mac OS X, Linux, and Solaris, and 10.3.185.23 and earlier on Android, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, as exploited in the wild in June 2011.

Sounds pretty nasty, at least the patch is out for it – but as usual, how many people will apply it in a timely fashion?


When Adobe patched the vulnerability last week, it conceded that exploits were already in use.

Adair also said there’s been an increase in Flash-based attacks. “There has been an ongoing assault against Flash Player for several years now, but especially so in the last three months,” Adair said.

Adobe has patched Flash Player four times in the last two months, and six times so far this year. Of the six updates, five addressed “zero-day” bugs that attackers were already exploiting at the time the patches were issued.

Brad Arkin, Adobe’s director of product security and privacy, acknowledged the problems in keeping ahead of attackers, but blamed the popularity of Flash Player for the attention.

“The installed base [of Flash Player] is a real big part of it,” said Arkin. “It’s such a widely distributed technology that attackers find it worthwhile to invest the time to carry out some kind of malicious activity. They’re making an investment for the biggest return possible.”

Arkin also argued that attackers get more bang for their buck by rooting out Flash vulnerabilities than they do looking for bugs in individual browsers because virtually every personal computer has the Flash plug-in installed. “Flash is the code [used in the browser] that has the highest market penetration,” he said.

According to Adair, the exploit of CVE-2011-2110 has been in use since June 9, five days before Adobe issued its latest security update. Arkin corroborated that timeline.

Adobe does claim to be more pro-active about patching than Microsoft – which honestly isn’t really hard is it? Brad Arkin the head of security said:

I think we’re more aggressive than Microsoft, basically, if we have information about attacks in the wild, or if the information is out there on a mailing list — which means attacks are imminent — that tends to be a trigger for us to think about an out-of-band.

Do note they said ‘think’ about a patch though and not ‘issue’ one.
