Posted by timothy on from the oh-the-files-are-inside-the-death-star dept.

New submitter fran6gagne writes "AT&T [Monday] notified customers of an effort by hackers to collect online account information. It is not believed that the perpetrators of this attack obtained access to sensitive information." eWeek's account has a bit more detail.

      I think the title is saying there was an attack that tried to get data (Users' data was the target) from AT&T ('Targeted attack' on AT&T). Definitely a confusing headline but not actually redundant.

      Yes, I was partly being compulsively silly. The quotes convey the extra info that AT&T describes it as a targeted attack. A title without repetitition of words might have been "Targeted attack" for AT&T user info" or something...

    When I signed up for a UVerse account, they provided the login details. They had my username (previously tied to DSL), no biggie. But then the technician at the house was able to pull up my password. MY password. It's stored in a reversible manner (if encrypted at all)- why the fuck? This does not surprise me that AT&T was targeted, and I'm sure they have millions of customers that believe they password is safe. Since then, I don't trust AT&T or that account for anything important.

      Believe it or not, AT&T is actually pretty serious when it comes to sensitive personal information.
      ( I have to re-take the training at least yearly about it )

      Full drive encryption on all desktop and laptop systems are pretty much the standard. Software firewalls and
      anti-virus updated constantly. Forced password changes on a scheduled basis with complexity rules in full
      effect. Access to servers which hold SPI are limited and those accounts are either passphrase level logins
      or RSA SecurID tokens.

      ( All tokens were re-issued post RSA Data breach )

      Network sniffers are in place everywhere. Firewalls are in place to isolate the many internal networks
      within the company. Identifying the systems with your data is only part of the puzzle. Getting access to
      them ( and the network they reside upon ) is a lot more work for an outsider.

      Not just anyone in the company has access to your data. Only those groups that need access to it to do
      their job. Will it stop the official evil employee from looking at your data if they have legitimate access ?
      Of course not. You have to trust SOMEONE to access your data when necessary.

      From an outside hack perspective though, the systems in general are definitely not wide open for the
      world to see. They may not be up to NSA / Area-51standards, but they're pretty locked down.

      AT&T is a multi-headed beast of a company with dozens of divisions. It's highly likely that in your area, AT&T may be highly security conscious while in the UVerse area, they couldn't secure two pieces of paper using a stapler... having reversible encryption is an incredibly bad security exposure (GP post's anecdote).

      Forced password changes on a scheduled basis with complexity rules in full

      This has actually proven to be bad, as folks will likely resort to writing down their passwords... or if they infrequently use the system, they just keep using the "forgot, email me" feature.

      I used to work for ATT. People working in the same building don't even know the job responsibilities of people across the hall... much less across the country. ATT would do things like: Give one of their departments a free data line. This line was still billed, but they'd put it on an account that was paid by ATT itself. There were thousands of lines on these accounts and they'd bill in the millions, but it didn't matter because ATT would pay it themselves right? Well, the problems arose when ATT would lay-off the previously mentioned department. They'd fired everyone, and vacate the building. A few months later a new tenant would move in and find several WORKING T1s on the ATT network... some of them inside ATTs own internal cloud! They'd call ATT billing and request to have those lines removed... ATT would say they need a written statement ending service to disconnect. The tenants would explain that ATT was the customer, they need to write their own disconnect request... but ATT would refuse. Dishonest people would say "Fine" and write a fake disconnect request. (that actually would work) More dishonest people would just start using the T1s and say "Yay!" Honest customers, as usual, were screwed. ATT would let the line sit, usually for years, then figure it out and try to back-bill them for something they never asked to have installed, never used and had no way of removing.

    It appears that they are just enumerating which phone numbers are set up with online account access. This can be done via the account setup page. The login page itself will not tell you if an account exists or doesn't exist, but the setup page will. Likely, this is a first step to later brute force passwords. Given that the username is the phone number, they can then just try and find one that has an account set up with AT&T's web site.
