Exposing Bots In Big Companies
CalicoPenny let us know about yet another "30 days" effort, this one to name the names of major companies infected with spam-spewing bots. Support Intelligence began the effort on March 28, out of frustration at not being able to attract the attention of anyone who could fix the problems at these companies. While they haven't named 30 companies over the ensuing month, they did name some prominent ones, such as Thompson Financial, Bank of America, and AIG. The scary part is that if a bot can spam it can capture keystrokes or troll for interesting documents.

Or troll slashdot.
The opposite of progress is congress
to "kicking bot and posting names."
Lacking <sarcasm> tags,
Aside from IT efforts to clean up (or at least keep their heads above water), the percentages would likely compare favorably with the home user population at large, methinks. Sometimes (like ferinstance the company I work for) can be outright anal about security (custom images, email that's filtered nine ways from Sunday, etc), and yet about once a month scans will pop up someone who has been bit with the latest variant of (insert malware here). To their credit, the guys here remove it often within minutes of detection- never seen one last more than a couple of hours. (not just saying that because I happen to be a sysadmin there, seriously... the user-end guys are anal about that sort of thing, and if they weren't the network guys would happily shut off the offending port @ the switch to get the user's attention).
Quo usque tandem abutere, Nimbus, patientia nostra?
How long before some company tries to cover up the embarrassment by suing the people who disclose the fact that they have machines infected with bots? They might not succeed, but they might make life unpleasant for a short while for those who post the info.

Answer: they're usually the height of mediocrity. The best and brightest, if they're there, are often ignored.
The notion that lots of big companies have spam bots all over the place is not all that hard for me to believe. Their IT divisions are often poorly staffed with folks who were selected with more input from HR than from the actual manager. They look at the certificates and then decide if a person is OK for the job. Honestly, the certificates are not a good gatekeepers to ensure that people without a clue don't find themselves on the front line. They can't be.
We all have known people who were extremely good at passing tests, but for reasons unknown to the rest of us, are unable to use those very skills in a real application. Those are the people who all too frequently end up in big organizations, pretending to know what real IT is. There is no substitute for learning from experience.
And these corporations are about to have one of those learning experiences. It won't be pleasant.
Nearly fifty percent of all graduates come from the bottom half of the class!
...along with the deinfestation, a little education might go a long way. If employees could be paid to attend a (mandatory) presentation on just how a botnet gets set up, I bet this would reduce the instances of infections by an appreciable amount. (Yeah, not 100%, I know.)
Make it interesting. Start out asking for people's opinions on spam. Get 'em good and worked up. Then set up some network monitor with a nice, easy-to-see graphic interface (maybe write one) and demonstrate how a workstation gets infected by the user running a compromised app. Once it takes hold (pick a good one), pull out the stopwatch, tick off 5-10 seconds, then show how many mails it sent. Then do the math; multiply those ten seconds by 6 to get minutes, then 60, to get hours, then 24. I bet even the math-challenged will get the point quickly, looking at those really large numbers.

It scares me just how prevalent this type of software is.. not just the spam bots but the malware and other stuff meant to steal data. Locating+shutting down spambots is the easiest task. I'm pretty small time but I found something interesting once while working with a new client to get them fixed up with antivirus and internet monitoring software (squid+sarg). I'd locked down some things and I kept noticing one PC trying to connect to yahoo every week at about 2:00 am. Long story short it was apparently attempting to email a 500kb attachment... that was apparently a log of everything typed in the week before and some other stuff. That *almost* went unnoticed. That type of infection is downright scary.... who is going to notice a 500kb email going out through an https connection at yahoo? It didn't even seem to be part of a command+control network... just gathering info??
The spambot infections is just the most visible symptom of a larger problem... they're talking about some "big name" companies apparently, but it is the smaller and medium sized businesses that really make the world tick... it is simply too complex, challenging and costly to really secure windows boxes without severely compromising functionality. It is also apparently not something that lends itself well to automation... I see big companies using enterprise software to "lock down" workstations and "reset" workstation images as their solution but there isn't really a small business answer here that I know of. If the tools were better/easier to use it might be easier to keep an eye on one's "flock" but it is a horrible pain both in setup and upkeep to really anticipate what might be happening. The entire stack one could use in windows to manage this stuff, from Event Logging to vb scripting automation, and all the way up to group policy is half-assed at best. This is the type of result you can expect.
this type of story is why I think that learning and/or heuristic scanners (both at the machine and router/firewall/proxy level) are pretty much the only way we can win. I'm not imagining something sentient, mind you, just something that will sift through all the event logs and point me toward things actually worth my attention instead of "every little thing".
Surely, these large companies could block outgoing port 25 traffic, except for their own email servers. Then the traffic can easily be monitored and spam zombies detected.
Why is this not "best practice"?

Uh, yeah, that's why, like, some of us actually run a secure operating system instead of freaking Windows.
I look forward to the day when proposing a Windows SOE is a firing offence. As for the state of American IT... Aren't you guys supposed to have landed on the moon, way back before Microshit was founded? WHAT HAPPENED TO Y'ALL?
you had me at #!
Exposing bots in big companies? That's easy. I see 'em every day. We even have a nickname for them here..."Middle Management."
In Soviet Russia, Chuck Norris will still kick your ass.
This is actually pretty big news.
My understanding is that Sarbanes-Oxley imposes strict IT standards for public companies.
If the companies involved are indeed Fortune 500 companies then they are exposing themselves to massive lawsuits.
In the big company that I work in this couldn't happen: we have good firewalls, machines are locked down in terms of downloads, machines are regularly tested/audited and we have a great IT department.
If I were a CEO of one of these companies I'd be looking to fire the CIO...
Am I wrong? Should I publish the list of companies that I know had bots on their networks in March?
If you mod me down, I shall become more powerful than you could possibly imagine.
Some Linux distros have automatic online updating. Unlike Microsoft, they put out updates as soon as they have them instead of waiting for a monthly cycle. I remember one afternoon my system downloaded about a dozen updates, then, just after the updater finished, it checked again and found four more. If your company is using one of those distros, those 100,000 desktops will patch themselves within a few hours after it becomes available.

I think it is interesting that we see "report cards" that give government agencies low grades on security, but publicly-owned corporations get a pass.
I seriously doubt that there are any botnets like this running on, say, the DoD network, yet they get a poor grade on security, while a frigging -bank- is pwned, and nobody is too bothered.
A house divided against itself cannot stand.
Absolutely. But -if you are monitoring your FW logs-, you will see the not so cleverly-written ones, and they can be your "canary in the coalmine". If you are seeing any denied outbound attempts, you know that either someone (or some software) is going against policy, or you have a workstation weakness that is being exploited, and you follow up on it.
Sure, this doesn't guarantee that you don't have a problem (ie., cleverly-written malware). You must take a layered approach to security strategy to be effective. Discounting a layer because it doesn't take every single possibility into account is ridiculous. That's why you have depth built into your security strategy, because no single layer works for everything.
That is the problem with most "security solutions" that are being peddled to CIOs, they claim to be a single magic bullet when real security solutions are more about correlation and follow-up from different layers. Not sexy, but very effective.
