Hacker May Be Exposing eBay Back Door

Posted by Zonk on Fri Feb 23, 2007 04:30 PM
from the maybe-buy-a-hackerproof-door dept.
pacopico writes "A hacker specializing in eBay cracks has once again managed to masquerade as a company official on the site's message boards, according to The Register. A company spokesman denies that 'Vladuz's' repeated assaults on eBay point to a larger problem with the site's security. Of course, eBay two days ago claimed to have found a way to block Vladuz altogether, only to see him pop up again. The hacker himself made comments indicating that the company's email servers are connected somehow to the financial information eBay hosts."

          Publishing this sort of thing privately often doesn't work. I've had numerous security vulnerabilities ignored for years: the use of public FTP sites with user's private passwords is one of the most common. Publicly write-able home directories used by both bosses and their secretaries is another: so are password free SSH keys and software that stores passwords locally in clear text, then NFS export those directories.

          In practice, nothing forces a change faster than an obvious break-in that discomfits the boss's secretary: the second fastest is something that affects the stock price. Even something that is being actively used for break-ins is often ignored due to recalcitrant developers and users who cannot be troubled to use secure practices, or to invest in keeping their software upgraded. The worst of them are those who think "we're inside a firewall, we trust the people we work with!". Then they sneak in a laptop from home and expect it to just work.

      According to Netcraft [netcraft.com], eBay appears to heavily use Microsoft software for their main North American operations. If that list is correct, it seems that most of their sites run on Windows 2000 or Windows Server 2003, using IIS 5.0.

    ...eBay is just a venue for people to exchange items, such as malicious code into an unexpecting user's browser.

    When will they learn to do something simple like disallow META tags in item descriptions to stop redirects to sites with malicious code, rather than to hide such things and disavow any responsibility.

    • Second this, My browser got hijacked. What they do is post a legitiment auction, then, after it has been approved, they change the images to pornagraphic ones to entice clicks. Once they get a click, the Meta tag redirects and injects exploit.

Maybe this guy has some motive behind his actions, but if you're in the world of IT Security you are relatively familiar with Romanian whackers. They can take the most mundane abuse of something and claim it as hacking. This is a perfect example. Is someone cracking, phishing, or scamming their way onto eBay's message boards that much of a "prank" or "hack"? I do not think so. Does it spell out that there is a security weakness somewhere? Absolutely. You will find this in almost any large organization when someone specifically targets them, their employees, and/or users. I cannot begin to account for how many times various ISP have been publicly hacked/owned/pranked, far worse than this.

    Do that many people really get their news from eBay message boards? This guy is getting on account and posting messages. What is his next hack going to be? Use a stolen or fraudulently created account to post a *FAKE* auction? This guy can hardly penetrate systems at will. I think there's a reason he only seems to pop up at certain times.

      Your choice in Operating System does little to mitigate bad coding. eBay has never been known for their technical wizardry and coding sophistication. It wouldn't surprise me if their back doors were wide open. (If you knew where to look.) For example, instead of having secure B2B messaging channels between different offices and departments, they might use machine formatted Internet Email that gets decoded by machine on the other side.
