From BankInfoSecurity.com (BIS):
On Oct. 7, the District Attorney of Queens County, N.Y., and City of New York Police announced the results of a two-year investigation that resulted in the biggest identity theft takedown in U.S. history.
The elaborate scheme, which involved five organized crime rings with ties to Europe, Asia, Africa and the Middle East, resulted in financial losses exceeding $13 million over a 16-month period.
So far, 111 individuals have been indicted, and authorities say 86 are now in custody.
The operation was dubbed “Operation Swiper.”
The criminals focused on credit card fraud, using stolen credit card numbers which they then used to create counterfeit credit and identification cards. Skimming devices were used in restaurants and on bogus websites to obtain the credit card numbers.
“The counterfeit cards were supplied to hired shoppers who were instructed to purchase high-end electronics and other merchandise, items that could easily be fenced and re-sold, usually over the Internet. Some of the shoppers also have been accused of using counterfeit cards to stay in five-star hotels and rent luxury cars during their so-called shops. In one case, a shopper allegedly commissioned a private jet to travel from New York to Florida,” BIS reports.
This is why it pays to keep careful tabs on your credit cards.

, Patch Tuesday
Tuesday, October 11, is the second Tuesday of October and is the usual day when Microsoft issues security updates for its Windows products. This one contains two critical updates, so you will want to make sure that you turn your automatic updates on at your home PCs. (Mac users don’t have to worry about such things…) Here’s the scoop:
Microsoft is planning eight security updates next week – two critical – as part of its regular Patch Tuesday program.
The obvious highlight of the batch is a critical update for Internet Explorer that affects all supported versions of Microsoft’s ubiquitous web browser, including IE 9. The second critical update covers flaws in Microsoft .NET Framework and Microsoft Silverlight that create a possible mechanism for miscreants to inject hostile code onto vulnerable systems.
The bad news is that most of the updates will require system restarts. I suggest you set updates to manual on any application servers.

Hilarious YouTube video that one of my fellow Net Admins sent out this morning. So, I’m going to kick off the new month with a bit of humor. And watch for some scary Halloween-esque real-life security horror stores in celebration of the scariest month of the year.

If your computer is not properly patched (according to all the best advice I have given you), you are at risk of infection. According to Sophos, “Even after 3 years, Conficker is the still the most common virus. Since 2008, it has exploited unprotected computers, weak passwords and USB storage devices.”
The good news is that Sophos has released a Conficker Removal Tool that you can use to scan your system and remove the virus. I tested the tool and it’s very simple – no complicated installation or configuration. Naturally, the tool didn’t find Conficker on my system
If you suspect you have Conficker on your system, or you’re not sure, but want to check, download the tool and remove Conficker now. They, get your system security patches up to date. Please. The virus will just keep spreading until everyone is patched.
Don’t be a Conficker enabler…

We have a Skype room called the International Internet Marketing Group where we discuss various topics related to Internet Marketing. Last night, we had a discussion, which I led, about passwords and online security. Here’s an excerpt:
EVERYBODY here needs to LEARN this stuff today.

[9/26/2011 8:08:40 PM] + Ken Harthun (Co-host: TIIMG): Yes, 123456 is a good one. Also, can be one of the most secure passwords you can use. Anyone confused yet? Ready to lynch me?
[9/26/2011 8:09:09 PM] Marj Wyatt: have no idea, Ken
[9/26/2011 8:09:09 PM] ™ Gary Simpson: @ Ken – depends how you “conceal” it.

[9/26/2011 8:14:19 PM] ™ Gary Simpson: Agreed.
[9/26/2011 8:14:20 PM] + Ken Harthun (Co-host: TIIMG): It’s really a revelation1

[9/26/2011 8:14:41 PM] Kay Brasher: Agreed
[9/26/2011 8:14:43 PM] ™ Gary Simpson: ie Revelations.
[9/26/2011 8:14:50 PM] Maureen Amberg: Why can’t you have a password that noone could guess?
[9/26/2011 8:15:02 PM] Marj Wyatt: @Suzanne, except for DAP
[9/26/2011 8:15:03 PM] + Ken Harthun (Co-host: TIIMG): The correct answer is that Dog…… is a very secure password and easier to remember than XH@*222>>>@
[9/26/2011 8:15:22 PM] Marj Wyatt: That’s why I use Roboform!
[9/26/2011 8:15:23 PM] ™ Gary Simpson: @ Maureen – A brute force password attack will crack almost any English word so it’s
best to include some random characters to avoid the possibility of that.
(See Steve Lorenzo’s e-book/report on the most common passwords NOT to use.)
[9/26/2011 8:15:26 PM] -Bill Vallee (Leader:TIIMG): (whew) (wave) (flag:us)
[9/26/2011 8:15:38 PM] Suzanne Patricia Howarth: You are not saying why. please get to the point I need to go
[9/26/2011 8:15:40 PM] + Ken Harthun (Co-host: TIIMG): Gary, you’re stealing my thunder here.
[9/26/2011 8:15:59 PM] ™ Gary Simpson: Soz Ken. I will STFU. LOL!
[9/26/2011 8:16:14 PM] Dennis Pippin: so you mean dog with the dots?
[9/26/2011 8:16:45 PM] + Ken Harthun (Co-host: TIIMG): OK. here’s the scoop. You take any dictionary word, your name, your dog’s name, anything you want and PAD it with a personal password pattern that you will easily remember and you have an virtually unbreakable password.
[9/26/2011 8:17:05 PM] ™ Gary Simpson: EXCELLENT point.
[9/26/2011 8:17:35 PM] Steve Lorenzo: [Monday, September 26, 2011 8:06 PM] + Ken Harthun (Co-host: TIIMG):
<<< Gary, Steve, Anyone. What is the least secure password you can use.The MOST used password is
See the Most Used 500 Passwords here:
^^^ It is still free to get for you ^^^
But I’ll be releasing it as a PAID product WSO next week
[9/26/2011 8:17:54 PM] Tina Golden: Awesome tip, Ken, thanks!
[9/26/2011 8:17:57 PM] + Ken Harthun (Co-host: TIIMG): The secret is that the hackers don’t know your password. They will try dictionary words and common variations, but once you force them to use brute-force guessing routines, they’re lost.
[9/26/2011 8:18:00 PM] Maureen Amberg: I do not use a dictionary word…..and do add numbers or symbols. Is OK?
[9/26/2011 8:18:45 PM] Tina Golden: I use a name (not my own) and number combination
[9/26/2011 8:18:51 PM] Steve Lorenzo: One VERY important thing is
You do not need ONE password .. <<< dumbest thing to do, no matter how complicated it is!
[9/26/2011 8:18:56 PM] Tina Golden: But I like Ken’s suggestion
[9/26/2011 8:19:10 PM] Steve Lorenzo: But rather different passwords for each separate website
[9/26/2011 8:19:13 PM] + Ken Harthun (Co-host: TIIMG): Steve, I’ll use 123456 every day. Try to guess this one: +_..123456.._+
[9/26/2011 8:19:18 PM] Dennis Pippin: [Monday, September 26, 2011 8:16 PM] + Ken Harthun (Co-host: TIIMG):
<<< OK. here’s the scoop. You take any dictionary word, your name, your dog’s name, anything you want and PAD it with a personal password pattern that you will easily remember and you have an virtually unbreakable password.I don’t understand this
[9/26/2011 8:19:48 PM] Maureen Amberg: Excellent point Steve!
[9/26/2011 8:19:51 PM] Tina Golden: If you have a virtually unbreakable password, would it matter if we used it on more than one site?
[9/26/2011 8:19:52 PM] Steve Lorenzo: Ken, it’s not about me, but the hackers who would use software to try all the combos possible
[9/26/2011 8:20:04 PM] Steve Lorenzo: the simpler it is, the fastest they can push through it
[9/26/2011 8:20:11 PM] Dennis Pippin: PAD it with a personal password pattern…. this is what I don’t understand
[9/26/2011 8:20:25 PM] ™ Gary Simpson: @ Dennis – look what I did here:
[Monday, September 26, 2011 8:11 PM] ™ Gary Simpson:
[9/26/2011 8:20:34 PM] + Ken Harthun (Co-host: TIIMG): Once you add the padding, which is unkown to a hacker, and force brute force attacking methods, then length trumps complexity. Use anything you will easily remember, just add a pattern that you will remember and you’re good to go.
[9/26/2011 8:24:52 PM] + Ken Harthun (Co-host: TIIMG): @Marj. Brute force means you have to guess every character one at a time. It can take eons if your password is long enough.
Are you getting this?

, Data Theft
, Security best practice
Data leakage? What’s that, you ask? Well, it’s a growing security issue which has at its root, the explosive proliferation of mobile and portable devices and the exponential growth of social networking tools, instant messaging, and external storage devices. Simply defined, data leakage is “the intentional or accidental exposure of sensitive information ranging from personally-identifiable information to protected intellectual property and trade secrets” (Source: Data Leakage for Dummies, Sophos Special Edition by Lawrence C. Miller, CISSP). You can download your own copy here which, if you are involved in enterprise security like I am, I highly suggest you do.
The book outlines six ways to reduce data leakage risks, but I consider only five to be relevant and my order of importance is somewhat different. That probably doesn’t matter in the overall scheme of things as longs as all the bases are covered. Here is my top five in order of most important to least important:
- Device control – policy should be in place to control who is issued mobile devices such as laptops and smart phones based on roles and responsibilities. Policy should also include how staff, contractors, etc. may use removable storage devices such as external hard drives, USB thumb drives, CD/DVDs, cloud storage etc.
- Encryption – laptops should be issued only with full-disk or file-level encryption. Employees who use USB thumb drives to occasionally move data around, or take it home to work on (yes, I know this isn’t best practice, but people do it anyway) should be instructed in the use of security that is normally provided on today’s leading USB storage devices.
- Anti-Virus – it goes without saying that ALL endpoints must have complete anti-virus/anti-malware protection to prevent hackers for accessing sensitive data through trojans and malicious links. Security policies should be implemented in Group Policy and automatically applied to any device connected the network.
- Network access – strict policy should be in place to dictate who is granted access to the network and what level of access they are granted. Traffic in the network should be segmented so it can be monitored and any potentially insecure segments should be locked down tight.
- Application control – User-installed applications increase the risk of data leakage in your organization. Third-party IM, games, VoIP applications, and P2P software should be tightly controlled and if allowed should be thoroughly tested and vetted by the IT department before approval is issued.
These five areas form the basis of a comprehensive security policy to prevent data leakage in your organization. They also apply to your personal information.
Give them due consideration, won’t you?

This snippet from SANS NewsBites Vol. 13, No. 74, 16 September 2011:
Researchers have detected a rootkit that targets the BIOS, Master Boot Record (MBR), the kernel, and files of PCs. It has been at least four years since malware that focuses on BIOS has been found. Trojan.Mebromi adds malicious instructions to the BIOS that cause machines to becomere-infected when they are booted even after the master boot records has been cleared of infection. Mebromi is unlikely to become widespread as it affects just one type of BIOS. However, it raises the question of how to create a utility to clean BIOS and poses no risk of damage.
Regardless of whether or not this becomes widespread, it points up the reality that nothing in a PC is truly safe; indeed, routers switches and other networking equipment all contain IOS chips that can be flashed. In this case, it’s only one BIOS maker, Award. Here is an interesting flowchart put together by Symantec after they analyzed the trojan’s behavior:
Mebromi flowchart from Symantec
It’s almost too simple. I think we’ll be seeing more of this type of thing in the future.
