On top of that, Home Depot hired a person who had been fired from another company for sabotaging their network. According to this article on ars technica,
Home Depot hired Ricky Joe Mitchell as its senior IT security architect. Mitchell got the job after being fired from EnerVest Operating in Charleston, West Virginia—and he sabotaged that company’s network in an act of revenge, taking the company offline for 30 days. Mitchell retained his position at Home Depot even after his indictment a year later and remained in charge of Home Depot’s security until he pled guilty to federal charges in January of 2014.
Well, duh! Is it any wonder that Home Depot suffered a bigger breach than Target? Target’s was bad at 40 million credit cards stolen; Home Depot’s was worse at an estimated 56 million. The malware in both cases was the same, “BlackPOS” (a.k.a. “Kaptoxa”), a malware strain designed to siphon data from cards when they are swiped at infected point-of-sale systems running Microsoft Windows,” says Brian Krebs.
From the ars technica piece: “…former employees contend that the company relied on out of date antivirus software—a version of Symantec’s antivirus purchased in 2007. And the company didn’t perform network behavior monitoring, so they would not have detected unusual network traffic coming from point-of-sale systems.”
Hate to say it, but they were hoisted by their own petard.
For the first time in a very long time, I’m not writing about a Windows vulnerability. Though Windows is infamous for its insecurity, there are other operating systems that also have have security holes, Unix, Linux and MacOS (based on Unix) being the top three. iMacs and MacBooks aside, most of the internet runs on routers and other devices that have embedded Linux/Unix operating systems at their core.
For those of you familiar with Linux/Unix, you know what Bash is. For those of you who are diehard Windows people, Bash is the Unix command shell that allows you to manipulate the operating system using text commands, similar to what you can do with the Windows command prompt (although Bash is more powerful).
Bash has a Remote Code Execution (RCE) bug and here’s what’s up with it:
“Everything from Unix, Linux and Apple systems, to servers, routers and network-attached storage devices are potentially at risk,” according to Alan Woodward (interviewed by Mathew J. Schwartz in Bank Info Security). If your company uses any of the previous platforms, you may be at risk. Those who use Windows systems are not affected.
Get more info about the exact details of the vulnerability here.
Again, if you’re running Windows systems, these are not affected. However, you should do the following on any other devices:
- Patch the Bash flaw by upgrading all Linux/Unix-related software;
- Disable remote log-in on all Mac OS X systems, until Apple patches the vulnerability;
- Check every device that runs or relies on an embedded version of Unix or Linux, to see if they’re susceptible to the vulnerability, and patch their software or firmware accordingly.
If you’re a profit-motivated cybercriminal willing to invest a couple of hundred bucks on some technology, you can easily steal anyone’s PIN at most retail card terminals.
“What?” You say. “That’s not news!” Well, it is when the cyber-criminals are your own government agencies. I’m just going to block quote this from Bruce Schneier’s latest Crypto-gram newsletter:
There’s a new story on the C’t Magazin website about a 5-Eyes program to infect computers around the world for use as launching pads for attacks. These are not target computers; these are innocent third parties.
The article actually talks about several government programs. HACIENDA is a GCHQ program to port-scan entire countries, looking for vulnerable computers to attack. According to the GCHQ slide from 2009, they’ve completed port scans of 27 different countries and are prepared to do more.
The point of this is to create ORBs, or Operational Relay Boxes. Basically, these are computers that sit between the attacker and the target, and are designed to obscure the true origins of an attack. Slides from the Canadian CSEC talk about how this process is being automated: “2-3 times/year, 1 day focused effort to acquire as many new ORBs as possible in as many non 5-Eyes countries as possible.” They’ve automated this process into something codenamed LANDMARK, and together with a knowledge engine codenamed OLYMPIA, 24 people were able to identify “a list of 3000+ potential ORBs” in 5-8 hours. The presentation does not go on to say whether all of those computers were actually infected.
Slides from the UK’s GCHQ also talk about ORB detection, as part of a program called MUGSHOT. It, too, is happy with the automatic process: “Initial ten fold increase in Orb identification rate over manual process.” There are also NSA slides that talk about the hacking process, but there’s not much new in them.
The slides never say how many of the “potential ORBs” CSEC discovers or the computers that register positive in GCHQ’s “Orb identification” are actually infected, but they’re all stored in a database for future use. The Canadian slides talk about how some of that information was shared with the NSA.
Increasingly, innocent computers and networks are becoming collateral damage, as countries use the Internet to conduct espionage and attacks against each other. This is an example of that. Not only do these intelligence services want an insecure Internet so they can attack each other, they want an insecure Internet so they can use innocent third parties to help facilitate their attacks.
The story contains formerly TOP SECRET documents from the US, UK, and Canada. Note that Snowden is not mentioned at all in this story. Usually, if the documents the story is based on come from Snowden, the reporters say that. In this case, the reporters have said nothing about where the documents come from. I don’t know if this is an omission — these documents sure look like the sorts of things that come from the Snowden archive — or if there is yet another leaker.
No government agent or agency should be permitted to consider themselves above the law. What they are doing, you and I would be arrested and imprisoned for. I think it’s time we called these criminals to account for their crimes. Snowden did his part; it’s time for us to live up to our responsibilities as citizens and give these crooks the business.
The so-called “warrant canary” was first issued in Apple’s debut transparency report. Apple and other companies are not allowed to disclose whether or not they have received a Section 215 order under the Patriot Act, because the orders are classified.
Apple, however, preemptively asserted [it] “never received an order under Section 215 of the USA Patriot Act,” in November 2013.
That text has now been removed from its latest report, suggesting Apple has in fact received such an order.
BoingBoing reports this:
The premise of a warrant canary is that Section 215 of the Patriot Act can compel companies not to tell anyone about being served with a warrant, but that the law can’t compel a company to lie and say that it hasn’t received a warrant. This has not been tested in court yet.
It seems likely, based on the latest report, that Apple has now received at least one of the secret surveillance requests.
Ian Paul, writing in the Security blog for PCWorld, gives us three warning signs that email is malicious:
- Dear Customer — an email not addressed directly to you using your registered name [or, with no salutation at all. Ed.].
- A weird looking link that is confusing and not obviously from the source. [Here’s a good one: http://twierdzaprzemysl.za.pl/qjjaonoars/<redacted>html]
- An attachment
To that list, I would add blatant grammatical errors that make it obvious the sender does not have English as a first language. Example: “It’s operated by Dropbox and safety” in a message I recently saw.
And one more thing: Were you expecting to receive that email? Even if it says it’s from someone you know, you know the types of things your friends send you. If you get lots of emails about cats from one of your friends and then start getting emails about foreign lotteries, you can assume something’s up.
Stay on your toes and think before you click.
The proliferation of public WiFi hotspots has certainly made it convenient for mobile users, but it has also make it riskier. You have no control over the security features implemented, if any, and you have no way of knowing what they are. Therefore, you have to be extra cautious when using public hotspots.
- Do not access sensitive personal accounts such as your bank or credit cards
- Ensure that any websites you visit use HTTPS and display a lock icon
- Watch out for “shoulder surfing” from people and be aware that security cameras may be recording you, too
- Never use a public computer kiosk, such as one in a hotel lobby or “business center” to access personal information
People are creating a “new” profile of someone and then they add the target’s friends, hoping that since you know them, you will add them. As part of the ruse, they make up some excuse as to why they had to create the new account. They will message you about winning a lot of money or some other reason, and try to get you to go to some site and sign up, etc., etc. I know someone whose account was spoofed, and I have a friend who had a relative’s account spoofed.
Facebook will immediately disable the fake account if you report it promptly. If anyone tells you they are receiving strange messages from you, investigate and make sure your account hasn’t been spoofed.
Let your friends know that they shouldn’t be receiving any friend requests from you, since you are already connected.
But until something I’m not expecting blindsides me and causes me a bit of inconvenience, I’m not going to install the bloatware on my systems. Most of it doesn’t work anyway and when users insist on clicking on scary popups because “of course I don’t want 10,000 viruses and registry errors and fix it for me now, please” all the while ignoring the warnings of their legitimate AV application, what’s the use? They bring those systems to me, all horked up with random junk and I find that they have AV software installed, but they opted in to all the adware that’s ******* up their computers anyway.
I don’t click on random links and I ignore popups. I’m a professional, of course, and I have everything backed up all the time and if I ever see a popup, I first ask, “Is this from an app I have installed?” I understand that most people have no clue and probably have no business owning and/or operating a computer.
But that’s why the cybercriminals are successful, isn’t it? Very few people are pros. Most of them will fall for anything.
My point is this: the AV companies are making money on people who they can’t help anyway. I may be wrong. Please tell me if I am. But 11 years of not running anti-malware software on my systems (I do occasionally do a safe mode scan, but I don’t run anything in the background) without a single infection on any of my systems is enough to convince me that smart computing and safe surfing practices is enough.

We security wonks constantly entreat our users not to use common words or phrases for their passwords, and certainly to never re-use passwords on more than one site. Another no-no is using keyboard patterns. The reason people do such things is that they are easy to remember. The problem is that the bad guys have all of these common poor password practices figured out and set up in their password cracking algorithms right alongside of their dictionary files and lists of hacked common passwords. With this exercise, I’m trying to get you to think randomly, not in patterns, though there is a pattern and symmetry here. Of course, no one will use this, but coming up with this stuff is just my way of having fun.
This novel approach that will give you a minimum of 10,000 secure pass phrases at your fingertips (or in your wallet or purse) using only the words. If you choose the modify it with numeric/special character options, you can get many more. If you do the math, the number of combinations of a group of characters is N^R, or the number of choices to the power of how many of those you use. In the basic method below, you have 10 choices and will use 4 of them, so you have 10,000 possible combinations. You can use this to securely write down your pass phrases (well, the aliases for your pass phrases) anywhere you want in the form of 4-digit numbers. Since no one will know what words are on your list, they can know your aliases but they won’t know your pass phrases. If you add secret complications (more about that in a minute), the number of guesses required gets astronomical (or should I say geometrical?)
First, take a piece of paper and write the numerals 0 through 9 on the left side. Then, pick 10 words that are familiar to you. You can use any common words or names that you will remember. Rules about not using pet names, kids’ names, your name, your spouse’s name, etc., don’t apply here because they will be used in a long and random combination. We all have at least ten of those. Here is my example (not to be used, of course–create your own):
Those of you who have ever taken a typing class will recognize those words and my slight alteration of it to fill the 10 slots.
Now, what’s the model year of your main ride? Mine is 2005. So, I write down 2005 as my alias and my pass phrase is BrownTheTheOver. Need another pass phrase for something? My birth year is 1953, so I use QuickDogOverFox as my pass phrase.
This method won’t win you any awards for password strength, but they’re sufficiently strong for most purposes. If you want to ramp them up, choose a numeral or special character that you insert between each word. It’s still easy to remember, but it adds 3 more characters to your phrase. I choose @, so I now have Brown@The@The@Over and Quick@Dog@Over@Fox. Visit Steve Gibson’s Password Haystacks site and check those out. My alias for those is 2005@ and 1953@.
The only thing missing here is a numeral to make the character domain consist of upper and lower case letters, numerals and special characters, so let’s add a numeral. Just put it at the beginning or the end and make your alias reflect that. Let’s use the numeral 7 and put it in front. I now have 7Brown@The@The@Over and 7Quick@Dog@Over@Fox. Your alias becomes 72005@ or 71953@ and the strength of the pass phrases goes geometrical, astronomical or what-have-you, into the hundreds of thousands of trillions of centuries to run a brute force crack.
Of course, this is entirely too much work for the average computer user, so I’ll still try “password” as my first guess, followed by “12345678,” “letmein,” and a few others.
