If you haven’t already heard, the code base for Symantec’s pcAnywhere was stolen in 2006, and bad guys are now using that code against the installed base of users in the wild.  This sort of compromise really isn’t anything that new or different.  But what is different is that Symantec is now telling users to flat out disable pcAnywhere until a fix is released.  Which is a good, smart move, but a better move would be to remove pcAnywhere and never, ever start it up again!

I remember the first time I used pcAnywhere; I was working my first helpdesk job and they let me finish part of my shift from home when I was doing mail server work, I could start up the scripts on the server, drive home and finish my work from there.  Being pcAnywhere, every couple of times I’d also have to drive back to work because the program would crash, but hey, an 80% success rate wasn’t too bad at the time.

Fast forward a decade (and more) to when I’m a QSA and pcAnywhere is still out there, and in all too many cases, it’s actually the same version I was using, or nearly the same vintage.  But it’s not me using it to manage a OS/2 Warp mail server (yes, OS/2 Warp), it’s being used to manage Point of Sales (POS) systems all across the US.  You see, mom and pop stores with POS systems don’t have a clue on how to set up a computer, so they find a nice, local service provider who will set up the POS for them, trouble shoot it when they have problems and just generally manage the system for a price.

Herein lies the problem.  If you’re a small, local service provider who makes their living servicing these folks, you have to be able to work quickly and cheaply with clients in a large are if you’re going to make a living.  You need to be able to get on their systems quickly to troubleshot problems and get them back online.  So of course you use a remote desktop client like pcAnywhere and you’re going to leave it directly exposed to the Internet since that’s the easiest way to make sure it’s always available and you don’t have to do a lot of troubleshooting of network equipment.  And you probably use the same password on all your clients, since you don’t want to have to rely on having the right password written down somewhere when the client calls screaming that they’re system is down.  After all, no one would scan for open pcAnywhere servers, nor would they guess the user name is ‘admin’ and the passphrase is “Let me in!” (at least it has complexity).  And you don’t worry about changing passwords when an employee leaves or updating to the latest patch levels.  In other words, a security nightmare.

In 2009, when I worked for Trustwave, one of the things that annual security report dug into was some of the repercussions of this type of remote management of POS systems.  And no surprise, one of the things they discovered was that remote desktop applications like pcAnywhere were one of the leading causes of small business compromises, especially compromises that involved either small chains or a group of geographically close stores.  An attacker would scan for the remote desktop client and then brute force the password and spread out to the other clients of the service provider.  Soon you’d have a whole segment of the local merchant community who’d been compromised and didn’t know how or why it’d happened.  And things have not gotten better since then.

I doubt things will change, I doubt most of the people who actually use pcAnywhere as a tool are going to even notice or read Symantec’s posting.  It’s the only way that the current business model works, not just in the merchant community, but in many other small business communities as well.  The service provider model requires remote tools, otherwise the travel time to and from locations kills any chance of making a profit.  Which means the folks who want compromise systems and steal credit cards are going to continue to have access to the remote desktop solutions. 

Still feels a little funny to be putting the ’12′ in the year column, doesn’t it?  I’m sure the feeling will go away by March or April.  And it’s getting started as an interesting year already, with Symantec’s source code and courts approving warrantless GPS monitoring.  I bet neither of those were captured in the “Top 11 Predictions for 2012″ so many pundits and bloggers put out at the end of the year.

Personally, I’m starting the new year with a ton of writing to do.  Despite my best efforts, I didn’t blog as much as I would have liked to in the last few months, but I know that has to change.  I have to start writing for the Akamai blog, I’ve got information for the Security Bloggers Meetup to post and I get several offers a month to write for other publications.  Then there’s the internal projects that are in motion, at least one of which is requiring me to think in new and interesting ways in order to get concepts on a page properly.  Plus I’ve got lots of interesting toys at work to play with; what questions would you be looking for answers for if you had access to the logs for a significant portion of the Internet?  That’s actually a serious question I have to blog about some day soon.  I’d like to hear what people want to see in a report.

And speaking of the Security Bloggers Meetup, I was nominated for two Social Security Awards last week.  Rich Mogull, Zach Lanier and I were nominated for the work we do on the Network Security Blog and I was nominated for Best Post for my “Curing the Credit Card Cancer” post.  Rich and I both sit on the committee that puts together the Security Bloggers Meetup, though neither of us works on the Social Security Awards, so before this year, we’d ruled that everyone on the committee was not eligible to be nominated.  Alan Shimel changed the rule this year; he felt that since we had nothing to do with the SSA’s, it was unfair to exclude us.  So, go vote for us. I’d love a chance to beat PauldotCom and the other contenders for Best Security Podcast.  I’ve read the other blog posts, I don’t have much of a chance for the Single Best Post.

• Lax security exposes voice mail to hacking, study says – Yes, using an easily spoofed phone # as your single method of authentication sucks.
• Kuwait wants to put an end to anonymous accounts on twitter – So they can put dissenting voices in prison.  I wonder if our politicians will follow?
• 440,783 “Silent SMS” used to track German suspect in 2010 – There may be a common thread to what I find interesting lately.
• Boot Hezbollah from Twitter or we sue, group says - Wha??  It would be censorship if it was the government asking for this.
• Stuxnet weapon has at least 4 cousins: Researchers – Who would have suspected that Stuxnet was only the first wave? (Hint: think everyone)
• No warrant needed for GPS monitoring, judge rules – This one worries me a lot.  You’re home may still be your castle, but your car definitely isn’t.
• Why Twitter’s “verified account” failure matters – Because, no matter what they do, identity is malleable and hard to prove.
• Defensive search-and-destroy ‘virus’ delivered to Japanese government – Maybe not directly related to Stuxnet, but the same general idea.
• Lilupophilupop SQL injections attack top 1 million infected URLs – Don’t try to pronounce the name of this attack.
• Symantec confirms hackers accessed source code of two enterprise security products – Two older products, but still in use in some locations, I’m sure.

Christmas is over!  I hope yours was good, but I personally find the whole build up and let down stressful and I’m glad when it’s done with.  Especially the part where my kids are home from school for a week and whine every time I tell them to get out of the house for a little while before I have to hurt them.  Not that I’d actually hurt my kids, but it’s sometimes the only threat that will get them moving. 

There have been some interesting stories leading up to Christmas and it’ll be interesting to see what’s been happening behind the scenes while the majority of us have been chomping on candy and ripping open our presents.  I have nothing to support the theory yet, but I strongly suspect most of the bad guys left their tools running while they took some time off, so their might be reports of compromises in the not too distant future.  After all, there were a couple of reports that came out before the weekend, perhaps hoping to get ignored and bypassed in Christmas craziness.

A quick thought on the boycott of GoDaddy over the SOPA legislation.  GoDaddy is such a minor player in this realm and probably signed on to the legislation like a little brother following his older brother, Big Media; they wanted to sound and act cool in the eyes of everyone else without having the faintest idea that what they were doing had real world consequences.  Boycotting GoDaddy is like bullying the little brother when what you really want to do is punch the elder brother in the eye!  It’s ineffective, both in the long run and in the short term, to boycott GoDaddy when what we should really be doing is making the larger players behind SOPA aware this is an evil and unacceptable way to try to regulate the internet.  A crowdsourced version of the list of supporters on the list is available as a Google doc.  If you really want to do something important, boycott some of the big boys on the list and quit going to their movies and buying their products. 

Open Tabs – 12/26/11

• Chinese computer hackers hit U.S. Chamber of Commerce – I wonder what our hackers are doing to the Chinese behind the scenes.  Not the vocal ones on the con scene, the ones employed by the Three Letter Agencies.  Never mind, we don’t do that, do we.
• LOIC (Low Orbit Ion Cannon) – DoS attacking tool – The tool is old news, but this is a pretty good writeup.  If you want to know more though, one of my co-workers could tell you a few things more about how it works.
• The Thought Leader … One year later – Chris Eng’s further harpooning of the information security thought leaders.  I know about half of the video applies to me at least as much as it does anyone else. 
• How hackers gave Subway a $30 million lesson in point-of-sale security – There’s another meaning for POS, especially when you don’t bother changing default passwords and trust owners to follow procedures.
• The Dark side of B-Sides – I’m staying out of this fight, since I know all the players.  But I know there’s a lot of truth to both sides of the stories, and the sooner this can be opened up and the aired out, the better for everyone involved.
• Hackers steal data on millions of Chinese net users – No need for nefarious government hackers when criminals will hack into Chinese sites because they data they hold might be worth something.
• Insurance against cyber attacks expected to boom – Let’s just insure our systems rather than taking the time to secure them!  Because the insurance companies won’t place caveats on what’s ensured and what constitutes a breach of contract to include poor maintenance control, will they?  “What do you mean our insurance doesn’t cover this?” is a phrase I expect to hear once cyber insurance (I shudder at the name) becomes common place.
• Congress calls on Twitter to block Taliban – Oh yeah, because it takes so much to set up another account and tell everyone to go there instead.  And because censorship should always be one of the first tools used by a free, democratic system.  These people spend too much time thinking in hyperbole and too little time thinking in reality.

Long night last night.  We went to something called a pirate gift party; sort of like a white elephant gift (cheap, person A can take a gift from the table or steal from person B) except most of the gifts were wrapped in tinfoil cleverly disguised to hide their true nature.  Two minor variations from a normal white elephant gift is that there is no limit to the number of times gifts can be stolen per turn and no one gets to open the gifts until the last gift is chosen from the table.  This led to an interesting ‘defense’ strategy; since there was a gift that was wrapped to look like Thor’s Hammer that my Spawn wanted, they worked together to make sure they kept it at all cost.  Basically, when person A stole the hammer from whoever was holding it, that Spawn would steal his brother’s gift, and that Spawn would steal the hammer back.  This was a pretty good strategy, until Spawn1 lost concentration at one point and went after a different shiny object.  It all ended up good in the end, though another pair challenged the Spawn to a game of endurance to see who wanted the hammer the most.  It ended up being a 15 minute round robin of gifts being stolen and restolen that left everyone laughing.  Oh, and “Thor’s Hammer” ended up being a cleverly disguised box with chocolate and money in it, with a broom handle that was acting as the handle.

Oh, and very importantly, It’s that time of the year! Security Bloggers Meetup invites have gone out.

Open Tabs 12/18/11:

• California creates special unit to fight computer crimes – It’s about time.
• Silicon Valley execs blast SOPA in open letter – I’m afraid that no matter how much we blast this piece of crud, it’s going to happen.  They’ll slip it by us some day, just watch.
• Mandates can’t alter facts – Here’s the letter itself, explaining why SOPA wouldn’t work in the long run
• China-based hacking of 760 companies reflects an undeclared Cyber Cold War – At least they didn’t say ‘APT’. 
• China’s cyberwar - More on the situation with China
• French President’s residence ‘busted’ for BitTorrent piracy – I wonder what it would look like if we started looking at our own Congressmen’s IP’s in YouHaveDownloaded.com?
• Researchers:  Google gamed browser report that dissed Firefox – NSS Labs is disputing findings in a recent report by Accuvant.  

When Rich isn’t around to take up most of the time, Zach can actually
be pulled out of his shell to talk for a little while.  Or maybe it’s
just when there are two hosts on the podcast there’s more time to talk. 
In any case, Martin and Zach went a little long this week as well as
deep into paranoia land.  And there’s so much in the news right now to
push us there.  It’s kind of scary when you start to realize that as
much communication as modern technologies allow, they also allow a lot
of very deep surveillance.  Which we as a society seem to be okay with.

There’s this game called Skyrim that’s been taking up all my ‘free’ time.  The only thing that’s kept me from being completely sucked in is the fact that my eldest son keeps asking, “When is it my turn to play?”  That and the fact that my other half keeps bringing up Christmas and my commitments as far as decorating and present shopping go.  Tis the season to avoid the malls and spend time online shopping instead.  Speaking of which, my coworkers have a thing or two to say about the holiday shopping season, which is once again morphing into something bigger, yet different, than it was ten years ago.  I love working at a place that has so much access to data about what’s really happening on the Internet.  Hopefully you’ll hear more on that early next year.

• 9 Reasons Wired readers should wear tinfoil hats – Except tinfoil actually improves reception for the mind altering rays!  Try a grounded wire mesh instead.
• Carrier IQ’s own marketing claims undercut its defense – Hard to say “We don’t invade users’ privacy” when all your marketing slicks say otherwise.
• Carrier IQ admits holding ‘treasure trove’ of consumer data, but no keystrokes – Yes, we invade your privacy, but only a little.
• Measure twice, cut once – Accuvant Labs is starting to do some fun stuff with vulnerability research.
• Spammers act just like HIV virus in avoiding filters – Why specific to HIV?  Because it was being given at on World AIDS Day.
• Feds seize domains of Korean movie portals – Why is DHS in charge of copyright infringement policing?  Don’t they have better things to do, like protecting us from terrorists?
• The impact of cloud computing on IT jobs – Why yes, a disruptive technology like the Cloud is going to cause some people to lose jobs.  And some people to get jobs.

I got home Sunday from 3 days in Las Vegas, two of which were spent at the first ever Minecon.  For those of you who aren’t the parents of Minecraft addicts or addicts yourselves, it’s a game where you create a whole world then mine it for resources and build just about anything you can imagine.  It’s multiplayer, sometimes massively so, and it’s very easy to set up your own server and be hosting it for the world in a matter of hours.  Unluckily, it may be too easy; people who can barely figure out what their IP address is are setting up servers on their desktops then sharing their systems with friends via Hamachi or simply opening their home network to the world. It’s enough to give a security professional an aneurism!  I wrote up my own experience in creating a cloud server for Minecraft in April, but that server never caught on with the kids.  So now I’m trying a different solution, MineOS Crux, a custom build distribution of Ubuntu specifically created for people who want a secure, lightweight Minecraft installation.  I’m running it as a VM on my Mac Mini server and exposing it to the world on a non-standard port, plus I locked down the distro a little more than the standard build.  I’m still more than a little paranoid about it, so if the kids aren’t using it, it’ll go away.

Oh, and the kids got me to start playing Minecraft as well.  Good thing there are a lot of long holiday weekends coming up.

• Death by Exception – As a recovering QSA (the taint doesn’t wash off), I can sympathize with Michelle’s frustration with exceptions.  It really isn’t an ‘exception’ once it becomes the rule.
• The “Off the Record” track – There’s really no such thing as “off the record”.  But for some reason, I’ve noticed that people become more guarded and less likely to talk when they first 
• AT&T tells users of ‘organized and systematic’ hack attempt – Glad to see they’re warning people and not invoking the “APT” card.  Yet.
• Hacker says Texas town used three character password to secure internet facing SCADA system – I wonder if the three letters were “APT”? 

Whether you call it Veteran’s Day, Pocky Day,Binary Day or something else, it’s Friday, I don’t know about you, but I’m looking forward to this weekend and spending some time with friends.  Being a parent, I don’t get out for adult time as much as I once did, which makes the rare occassions all that much more special.

If you know a veteran, today would be a good day to tell them thanks.  I ‘repaired’ radios long ago and far away on a little artillery base in Germany.  I put repair in quotes because our job was to say “Yep, it’s broken”, replace the radio and send the broken one off for repair by someone who actually did electronics troubleshooting.  I was lucky and my enlistment was during a relatively peaceful time, but we have hundreds of thousands vets out there who saw events and actions most of us can’t even imagine.  Please respect them for their sacrifices.

I haven’t done this in a few days, so there’s a lot of built up articles.

Open Tabs 11/11/11:

• Anonymous blasts El Salvador offline – I guess they found some soft targets.  
• How your signature can propel your security career – How are you putting your signature on the security at your company?  Don’t do what everyone else has done.
• Top 10 Security Voices on Twitter – I didn’t like @jgamblins list; half of the accounts on it are businesses.  Who would be on your Top 10 Security Voices list?
• Supreme Court justices concerned about pervasive, technology-enabled government surveillance – As they should be!  Wait until the government admits they’re also turning on the microphones and other sensors in your phone.  And don’t think they aren’t.  
• Judges weigh phone tracking – A little more to feed your paranoia.
• Doom, gloom and infosec – Of course our career field isn’t all feces and stench, but it’s not roses and cake either.  
• Cisco CSO:  Infosec pros should get back to basics – Yes, let’s quit buying all of Cisco’s blinky light solutions and get back to patching and policy.  That’s what he meant, isn’t it?
• ‘Biggest cybercriminal takedown in history’ – The hyperbole isn’t Brian Krebs’, but the rest of the article is some great stuff.  DNS can be dangerous stuff.
• Steam database hacked.  Encrypted credit card information and passwords compromised – First thing I had the spawn do when they got home from school yesterday was change their passwords!

I had a great time at BSides DFW this weekend!  Michelle Klinger, Joseph Sokoly and the whole crew of volunteers who made the event happen did such an awesome job of putting it together and the Microsoft tech center was the perfect place to have it.  Not that Jayson Street didn’t make a few of the security guards nervous from time to time.  And the rest of us nervous when he thought no one was watching where he was thinking of getting into.  I gave the closing key note speech, which went well despite the fact I was as nervous as I think it’s possible for me to be.  It’s worth giving the talk again some time, after I’ve tightened it up and loosened up a bit myself.  Just remember to challenge all our current security wisdom.

Saturday was November 5th, Guy Faulkes day, and despite it being a high holiday for Anonymous, nothing much seems to have happened.  They did pop Adidas last week, but that was supposedly a prequel to their main event this weekend.  On a more positive note, Brad Smith is doing slightly better, though he is still comatose and has pnemonia.  If you can, spare a few dollars to help Brad and his wife pay for medical bills; if you can’t, keep him in your prayers.  Brad has helped a lot of people in the security community and it’s time to help him in return.

• iPhone security bug lets innocent-looking apps go bad – And Apple shoots Charlie Miller (or at least his developer account) for being the messenger.

It’s almost time to hop in the car and head for #BSidesDFW (I even think in hashtags some days) in about an hour.  I find it annoying that I have to leave the house about 3 hours before my flight to have any chance of making it, since it takes 90 minutes to get to the airport and about 45 minutes to get through the TSA checkpoint most of the time.  I was joking around on Twitter earlier this week and said I’d vote for the first Presidential candidate, Republican or Democrat, who promised to abolish the TSA; it turned out that Ron Paul had already made that promise, but we’ll see if he’s still slugging it out by the time the primaries roll around.  In any case, I need to get packed up and head out.  I’m going to try to get a few interviews at BSidesDFW for the podcast, since there are so many interesting people speaking tomorrow.
