Acxiom Hacking Details Made Public

pgrote writes "As mentioned previously, the Acxiom consumer database company was compromised. More details have emerged including the background of the alleged hacker and the method used to gather access. It turns out he had access since December of 2002 and came in through an unsecured FTP server. The suspect was not a former employee of Acxiom as previously reported, but an employee of data mining company."

      Well the article I read said he was an employee of data mining company. Which means he had some inside knowlege of the systesm. He broke in through an external FTP server and did not get through their firewall. So I think Acxiom deserves a little break. There is no such thing as a 100% secure system, especially with inside knowlegde of the systems. As a programmer for a fortune 500 company, I could literally bring that company to it's knees and cause millions (USD) lost per day. However, I don't do that because I am a professional and would not use my skills to be abusive. I hope this dude get some hard time.

    How is it hacking if you publish it on your FTP server? I'm sure no one would call it hacking if the protocol had simply been http instead. Now, this fellow may have used the information for nefarious purposes, and if there is any law he broke in doing so, go get him. But I don't see this as hacking.

      This is ridiculous - if I'd encounter one, I'd ask myself if it was a honeypot.

      Also, the various journalists' view (and the subsequent picture created by them for their readers) of "hacking", "cracking", "security" etc. is sometimes so distorted, so far-off from the reality of the people closer involved with the subject that reading a mainstream-press article about it is often only marginally better than just making-up the facts from slashdot-postings !

      Not an admin, eh?

      Many _default_ non-anonymous ftp services on unix|unix-like systems that I have dealt (recently) with allow the ftp user the same access rights to the entire tree as their uid:gid is allowed. So, on a system w/o shadow passwords, cd /etc; get passwd; is all that's needed to get started. (grr ./ eats spaces...)

      BTW, shadow passwording has the achilles heel of file security. I have dealt with systems where the file security of these files had been comprimised to solve some silly need.

    This more or less shows the fact that many companies have group passwords to their critical equipment instead of inplementing a choke system to allow users to login into it to show them where they can go and cant go.

    Since they probably dumped the company involved and not changed any of those passwords then this guy was allowed to basically walk around at will inside the databases.

      Let's say I have a single lock on the handle of my front door... with no dead bolt. Along comes someone and kicks the door open and proceeds to rob my house. While he's robbing my house he steals a cd that I borrowed from my friend. Are you saying that *I* should be arrested because I failed to install an adequate dead bolt on my front door and thus the robber stole a cd that didn't belong to me?
      You're comparing apples to oranges. In fact, you're comparing apples to... zebras, or something not even closely related.

      The first distinction is that in your example, your friend willingly loaned you the CD. I don't think anyone has intentionally "loaned" their personal information to Acxiom. Before the initial story was reported here, I'd never heard of Acxiom, though various articles proclaim them to be [one of] the biggest data-mining compan[y|ies] around. If they have any data on me, I sure as hell didn't loan it to them.

      The second problem with your analogy is that a CD is nothing like personal data. A CD is a vanity, something worth maybe $15, less now that it's used. Acxiom has been described as serving "most top credit card companies and retail banks." What do you think the credit card or bank details of a single person - much less however many people were affected by this breach - are worth? That $15 CD pales in comparison.
      What's adequate? Let's say I did install a dead bolt but the robber was sophisticated enough to pick both locks? In this case I shouldn't be arrested because I had "adequate" security and was victimized by a "skilled" robber who had the proper knowledge that surpassed my own in lock technology?
      Your analogy fails here as well. You, as a private citizen, do not have any liability for the stolen items. Your friend loaned you the CD, there was no business agreement surrounding that friendly exchange. Acxiom is a business, the rules are different.

      Suppose you rent a storage facility at one of those mini-storage places. Their property is surrounded by a chainlink fence complete with razorwire. The gate requires a keycode to enter. Each bay is padlocked. Now let's say some joker breaks into the place, gets into your bay and steals everything you have stored there. Surely a fence with razorwire, key-coded facility access, and padlocks are "adequate" security... But you're damn sure that the mini-storage company would be liable for your loss, unless that was covered in your contract with them.

      But, see, none of us have a contract with Acxiom.

      Acxiom is liable, one way or another.

    ...but let's see what we can figure out from the article:

    The breach involved one FTP server outside the Acxiom firewall, the company said. No internal systems or internal databases were accessed, and there was no breach of the security firewall.

    Why did they have a server outside their firewall?!?

    The company said only a small percentage of its clients' data was involved in the incident, and the hacker, a former employee of an Acxiom client, was arrested.

    I guess they were trying to keep the article under a certain word count, because they forgot the word "alleged".

    According to law enforcement officials, the person arrested was a known sophisticated hacker. Acxiom said the person apparently gained access through the hacking of encrypted passwords.

    Okay, so this was probably little more than an attack against the /etc/shadow file if it's a UNIX box, or the SAM file if it's NT. In either case, I'm guessing they brute-forced / dictionary attacked the file with John the Ripper or the like. If that's what they did, how did they get the password file to begin with? Perhaps the FTP was a bit too willing to follow instructions? (recursion anyone? ;)

    After learning of the breach, Acxiom immediately moved to close the security gap and changed all passwords on the FTP server involved. The company is now in the process of communicating with all clients who might be potentially affected.

    Now, does that mean they had all users change their passwords, or just their passwords on that server? I wonder how many of those users have the same passwords on other machines as they had on the compromised FTP server...hmm.....

    "Acxiom is proud of its long-standing commitment to the security of our systems and our efforts toward continuous improvements in that area, so we deeply regret this breach," said Acxiom Company Leader Charles Morgan in the statement.
    Which is why their infrastructure was vulnerable to begin with? Why was their FTP server outside their firewall? Why aren't they using a Firewall proxy? How about FTP servers with jails? Without more details, it's impossible to be sure, but this smells like a successful attack due to careless configuration and insecure architecture

      Why did they have a server outside their firewall?!?

      I think that if you translate from Dumb Reporter to Technical you get "server on a service network or DMZ, available to the Internet but segregated from their internal network." That's standard practice, the thing has to be available to the Internet.

      In either case, I'm guessing they brute-forced / dictionary attacked the file with John the Ripper or the like

      Again, you need to translate here. Based on personal experience with similar organizations, I believe this translates to "He sniffed the plaintext (non-anonymous) FTP passwords off the Internet and used them to log in himself and get files."

      Now, does that mean they had all users change their passwords, or just their passwords on that server

      Translation: "We changed all the FTP passwords, so that they will be secure until the next time someone sniffs them.

      Which is why their infrastructure was vulnerable to begin with?

      Note that they also state the information he got was encrypted and not believed to have been used. It is not unusual for organizations like Acxiom to accept PGP or ZIP encrypted files via FTP. Obviously, that isn't good enough - if only because of the negative publicity that comes out of an incident like this - but that's what they do.

      The only sign of weak infrastructure here is FTP passing plaintext passwords over the Internet. I don't see any real evidence that anything else was compromised - except their PR shell.
