We are a long way to full disclosure in data breaches - even if we wanted to be!

I saw an article on PCWorld, written by Robert McMillan (IDG News), that according to the research firm Gartner -- not all data breaches are being reported by retailers.

I thought to myself ... here we go again ... burying our heads in the sand that all personal and financial information is hacked from retailers. Of course, that isn't to say that none of the stolen information is coming from retailers, either.

The conclusion was based on 50 retailers being interviewed and 21 of them saying they had been breached. Of these 21, allegedly only 3 had reported a data breach.

This led me to wonder if any of these retailers do business in an area, where disclosing data breaches is a matter of law?

My humble guess is that in the litigation happy society we live in today, no one is going to report anything unless they have to. As long as no one is certain (or they can get away with saying that) the information is probably buried, or someone comes up with a rationalization that it really didn't happen.

Going a little further, there has to be a lot of information being stolen that no one is even aware has been compromised. The fact that no one is aware it was compromised makes it easier to be used by the criminal element, effectively.

The sad truth is even if you could make computer systems bulletproof, human beings will continue to compromise information, either via social engineering techniques or to obtain financial compensation. We've made some of this information worth a lot of money.

Of course, information thieves often combine technology and social engineering, also. In the mysterious world of information crime, one shoe rarely fits all.

Right after reading the PCWorld article, I happened upon more research from Finjan, which might provide evidence that there must be a lot of computer systems out there that are NOT very "bulletproof."

As stated on Finjan's MCRC blog:

In our recent MPOM report, we reported on a Crimeserver hosting 1.4G of unprotected stolen data, including passwords, medical data, emails etc.

Many people asked us how we found the data. Was the data secure or not?

Although we cannot disclose all information to the public (for obvious reasons), I can say that the data on that Crimeserver was unprotected, meaning anyone could access it.

Today we came across another Crimeserver - it seems that we are finding one every other day...
Additionally, Finjan reported:

As we disclosed in our Q3/2006 Trend report, malicious code is hosted on caching servers of leading Search Engine Providers. This time we reported in our recent MPOM that stolen end-user data is also stored on these caching servers. Yes, your passwords, Social Security numbers, Online banking information …. no data is safe, as the examples below illustrate.

Even more alarming, it didn't take a lot of know-how to access all this information. The people at Finjan were able to do it, using simple Google searches.

I highly recommend taking a look at the entire blog post from Finjan (link provided at the bottom of this page) -- there are some alarming visual presentations indicating how much information is out there.

I'll include one, which shows a compromised (actual info blocked out) SSN:



The blog post also has visual presentations (screenshots) of user names and passwords to internal company sites, porn sites and online banking sites.

Now let me see ... if stolen information is being hosted on unprotected (anyone can access) crimeservers ... and it is being indexed (cached) by search engines ... it's probably safe to assume we don't have any real idea how much stolen information there is out there.

Also, please note it's safe to say not all this information came from retailers.

Last, but not least, I've seen commentary that we should blame Google for all this. First of all, I doubt that Google is the only place this information can be found. Another thing to contemplate is that thinking like this is as narrowly focused as thinking that retailers are to blame for most of the stolen information out there.

Unless we stop blaming each other -- we are going to be a long way from achieving transparency in data breaches. Exposing problems often is the first step in correcting them.

Until we embrace transparency, the people to blame (criminals) are going to be laughing all the to the bank.

Habbo Hotel Trojan Downloader poses as social networking site tool

Websense is reporting that a tool is being offered to "Habbo" users, which contains malicious code. The loaded tool is being offered by a third party software developer.

From the Websense alert:

Websense® Security Labs™ has received reports of a Trojan keylogger aimed at the users of Habbo, a popular social networking site for teenagers. As of last month, Habbo’s entry on Wikipedia said that over 8 million unique visitors access Habbo’s Web sites around the world every month. The party involved in spreading this malicious code poses as a third-party software tool developer for Habbo.

There seems to be very little out there about this, but I was able to find a BBC article from November about a teenager stealing $4,000 euros worth of virtual furniture using real money?

Based on the article, this isn't the first time (or probably the last) that Habbo users have faced the murkier waters of the Internet.

The article states:

A spokesman for Sulake, the company that operates Habbo Hotel, said: "The accused lured victims into handing over their Habbo passwords by creating fake Habbo websites.

"In Habbo, as in many other virtual worlds, scamming for other people's personal information such as user names has been problematic for quite a while.

"We have had much of this scamming going on in many countries but this is the first case where the police have taken legal action."

According to the article, there are a lot of spoofed Habbo sites, asking for user name and password information. FSecure.com did another article with screenshots of some of these spoofed sites.

In case anyone besides me is having a hard time understanding how real money is used to buy virtual furniture, Wikipedia offers a explanation:

Credits, also known as Coins in other websites, are the currency used in Habbo. Credits can be purchased using a variety of different services, such as credit card, a telephone service and via SMS. Credits are often given out as prizes for competitions held in the community. The Credits are stored in the user's purse accessible in any public or private room as well as on the Hotel view and while logged in on the website. Credits can also be redeemed into Exchange, which displays the Credits as an item of virtual furniture, the furniture can then be traded among users, and redeemed back into Credits.

At least now I can understand why someone would want to break into a Habbo account - they do have real money in them.

This might not have been the first time Habbo users have been exposed to assorted forms of malicious code. I found a discussion on Habbohut, a Habbo bulletin board, where the matter was being discussed in 2005.

Going back to the current alert from Websense, it has some pretty wise advice, which can be applied to any software tool being touted from an unknown source:

Websense Security Labs recommends caution when trying out new third-party applications developed for Web 2.0 and social networking Web sites, especially those with APIs open for third-party developers.

In other words, just say no!

DOJ is the latest badge of authority phishermen are using to net victims


This is the DOJ banner used in the screenshot of the phishy e-mail Websense is reporting. Please note, in this instance, I merely copied it right from the DOJ website. With minimal knowledge, just about anyone can do this with any picture from a website.

Apparently, Websense deserves credit for discovering a Trojan downloader pretending to be a e-mail from the Department of Justice (DOJ). Clicking on this attachment is likely to turn your computer into a zombie (part of a botnet) used to send more spam, or even worse used to steal information stored on your computer.

This might turn you into an identity theft statistic, depending what personal and financial information you store on your computer.

Here is the alert from Websense:

Websense® Security Labs™ has discovered a new email attack variant similar to attacks previously launched on the IRS and Better Business Bureau. The spoofed email claims to be from the United States Department of Justice (USDOJ). We have been tracking these attacks and have previously reported on them on our site.

The message claims that a complaint to the USDOJ has been filed against the recipient's company. The email informs the reader that a copy of the original complaint has been attached to the email.

The attached "complaint" is a Trojan Downloader .scr file with an MD5 of aeb784bc17c4c7e6edc5f1faaa9ed24f.

None of the major anti-virus vendors detected the malicious code.

Websense Security customers are protected from this threat.

In the e-mail Websense used as an example, it refers to a specific company. This means that this attack is possibly directly targeting people, who are associated with this company. This type of more directed attack has is now being referred to as spear phishing.

Spoofing (impersonating) government agencies is nothing new. The Phishermen use the badge of authority the name of these agencies invoke to trick people into clicking on the attachments in their spam e-mails.

The warning from Websense mentions that the IRS (Internal Reveue Service),BBB (Better Business Bureau) and many others have had had their badges of authority used to lure victims into the Phishermen's web.

I was unable to find a recent press release on this directly from DOJ, however a press release on a similiar attack using DOJ's name was released in June.

In it they speak to the fact that DOJ would never send a communication of this nature via e-mail:

The Department of Justice did not send these unsolicited email messages—and would not send such messages to the public via email. Similar hoaxes have been recently perpetrated in the names of various governmental entities, including the Federal Bureau of Investigation, the Federal Trade Commission, and the Internal Revenue Service. Email users should be especially wary of unsolicited warning messages that purport to come from U.S. governmental agencies directing them to click on file attachments or to provide sensitive personal information.

These spam email messages are bogus and should be immediately deleted. Computers may be put at risk simply by an attempt to examine these messages for signs of fraud. It is possible that by “double-clicking” on attachments to these messages, recipients will cause malicious software – e.g., viruses, keystroke loggers, or other Trojan horse programs – to be launched on their computers.

Do not open any attachment to such messages. Delete the e-mail. Empty the deleted items folder.

If you have received this, or a similar hoax, please file a complaint at http://www.ic3.gov/.
In this memo, they also offered some educational resources, which I highly recommend if you are unfamiliar with how the dark side of the Internet works:

Consumers can learn more about protecting themselves from malicious spyware and bogus e-mails at OnGuardOnline.gov, a Web site created by the Department of Justice in partnership with other federal agencies and the technology industry to help consumers stay safe online. The site features modules on spyware and phishing, at http://onguardonline.gov/spyware.html and http://onguardonline.gov/phishing.html.

One of the oldest social engineering techniques (sex) still seems to work!

Some would argue that sex is one of the oldest social engineering ploys to deceive someone into doing something they normally wouldn't do. As far as I know, it's been being used since biblical times.

Roderick OrdoƱez at the Trend Labs Malware Blog (Trend Micro) is reporting that malware is being downloaded on systems using a mysterious woman named Melissa, who strips off her clothing (in increments) when a user puts in the right CAPTCHA code.

CAPTCHA codes are those annoying letters and numbers, we have to enter in a box to prove we are human.

From the Trend Labs Malware post:

A nifty little program that Trend Micro detects as TROJ_CAPTCHAR.A disguises itself as a strip-tease game, wherein a scantily clad “Melissa” agrees to take off a little bit of her clothing. However, for her to strut her stuff, users must identify the letters hidden within a CAPTCHA. Input the letters correctly, press “go,” and “Melissa” reveals more of herself.
It appears that no one is completely sure what the malicious intent is with Melissa, but Roderick speculates that:

The CAPTCHAs in the example above were taken from the Yahoo! Web site, possible proof that someone may be building a huge base of Yahoo! accounts. For spam-related reasons perhaps? Although various methods of OCR (Optical Character Recognition) are already used to circumvent the CAPTCHA, this social engineering technique is new in that it uses people to unsuspectingly aid a malicious user.

The dangers of downloading all kinds of what I refer to as cybernasties are well documented on porn sites. A lot of these sites are owned by organized criminals, and unsuspecting users have had their identities stolen by going on them.

Here is a post, I did where British citizens were charged with a crime after having their identities stolen in this manner:

British citizens accused of child porn found to be fraud victims

The investigation that started this originated in the United States.

Recently, I did a post on hackers almost shutting down the State of California's systems, by misdirecting them to porn sites. In the post, I wrote:

As I've written before -- exercise extreme caution when clicking on porn sites, they often make your computer come down with a virus (or worse)-- especially if "safe surfing practices" aren't being used.

Interesting post from the Trend Labs Malware Blog with some rather revealing graphics, here.

Krackin software will crack your computer's security!


(Screen shot courtesy of Websense)

Krackin is one place you don't want to try to download music, or videos. The result will be your computer becoming what is known as a zombie, which will be used to spew out spam e-mails, which facilitate Internet fraud.

If you have clicked on this, I highly recommend reading the link in Websense's alert, which I have provided below.

Websense is reporting:

Websense® Security Labs™ has received several reports of a new Web site that is being distributed in spam sent out by those running the Storm attacks. For more details on the Storm attack, see (http://www.websense.com/securitylabs/blog/blog.php?BlogID=141).

This site poses as a new piece of software called "Krackin v1.2" and advertises:

* Easy to install
* Auto-Virus scanning* Mobile Source Downloading
* IP Blocking to Prevent Tracking
* Unwanted User Blocking

Users with unpatched computers are automatically exploited. Users with patched computers are prompted to download and run a file called "kracking.exe" This file contains the Storm payload code.

Websense alert, here.

On a final note, if you are a parent, this would be a good topic to cover with younger family members. From the appearance of the screenshot above, it would likely attract younger users.

Blogger fights back against the storm worm

Since Blogger has been kind enough to host this blog for about two years now, I thought I should do a post about the recent reports concerning malware and Blogger.

Blogger itself, wasn't compromised, but a lot of bloggers individual blogs were. Most people are compromised by malware after clicking on a link they shouldn't have.

This was posted on Blogger Buzz:

You may have seen stories in the news recently about malware on Blogger, such has this one from the BBC or this one from Committee to Protect Bloggers. Blogger was not compromised. Instead, the blog posts are from bloggers whose machines were compromised by a Trojan horse.

These bloggers had their mail2blogger email addresses in their computers' address books (a perfectly legitimate use case), so when the malicious software spammed every address in their address book with its content, a copy of that email was posted to their blog.

We are in the process of notifying impacted bloggers and recommending that they scan their computers and run current anti-virus software, available in the GooglePack. This is also good advice for all computer users, especially those who may have clicked the links in the emails sent by the virus. For more information about computer security, check out upenn.edu and us-cert.gov.

The BBC article mentions that Alex Eckelberry, who blogs at the Sunbelt blog was the first to discover the problem on Blogger. Please note, Alex himself is a Blogger user and the CEO of Sunbelt Software, a computer security company.

Alex has even been kind enough to help me, when I ran into a problem, or two doing this blog.

Alex has a pretty visual post (lot's of screenshots), which show exactly how the worm would be encountered in the wild.

Of interest, Alex also discovered that Blogger wasn't the only place, where people are being lured into downloading the storm worm.

From what I understand the intent of the storm worm is to turn a computer into a zombie, which becomes part of a botnet. Botnets are networks of zombie computers.

Botnets are used to send out spam e-mail and sometimes attack other systems in what are known as DOS (denial of service) attacks. They are also used to commit click fraud.

Of note, most Internet fraud can be traced to a spam e-mail.

Besides running a scan with good anti-virus software (to see if you've been compromised) -- the best defense is to learn how to spot the lures that are designed to trick people into clicking on them. In most instances, this will stop the problem before it happens!

Fake e-mail from the BBB stating someone complained about you is a scam!

If you get an e-mail from the Better Business Bureau stating that a complaint has been made against you - it might be a good idea to just delete it.

Websense is reporting:

Websense® Security Labs™ has received reports of a new email spam variant similar to an attack launched early this year. The spoofed email purports to be from the Better Business Bureau (BBB). The message claims that a complaint has been filed against the recipient's company. Attached to the message is a Microsoft Word document (Document_for_Case.doc), supposedly containing additional details regarding the complaint. The Word document actually contains a Trojan Downloader that, when opened, attempts to download and install a keylogger. This keylogger uploads stolen data to an IP address in Malaysia.

Keyloggers record the keystokes on a computer and then send them back to the crooks, who installed them.

They are normally interested in your password information, especially if it gives them access to personal financial data. That way they can rob you blind.

In case, you just have to know, whether or not, you've received a complaint at the Better Business Bureau, it might be a good idea to contact them independently to inquire into it.

Their website is here.

The best way to avoid becoming compromised is to have updated security software protecting your system and even better yet -- avoid clicking, or even opening unsolicited e-mails no matter, who they claim to be from!

FlexiSpy - software that spies on people via their smart phone


There is already a lot of "buzz" that mobile phones, especially those of the smarter variety, will be targeted for their "information value."

A product called "FlexiSPY" is being legally sold, which allows anyone (with the money to buy it) to invade the privacy of someone, who uses a smart phone.

Here is FlexiSPY's marketing pitch (from their site):

Catch cheating wives or cheating husbands, stop employee espionage, protect children, make automatic backups, bug meetings rooms etc.
If FlexiSPY is installed on a smart phone, it downloads data to their server 4 times a day, which can be accessed via the Internet by anyone paying for their service 24 hours a day, 7 days a week.

The FlexiSPY site blasts F-Secure, a security vendor, for calling their software a trojan, and claims FlexiSPY will not answer their e-mails. This is probably because F-Secure was the first one to question this software and it's potential abuse factor. The site claims F-Secure's true intent is to sell their own software, which can remove FlexiSPY.

This is partially true, billions are made in the spy versus spy (white-hat versus black-hat) world of computer security. Although, in all fairness, F-Secure isn't the only on record that is worried about the use of FlexiSPY's spyware.

According to FlexiSPY, their software IS NOT a trojan because it has to be loaded on a telephone by a human being, and the software doesn't replicate itself.

I wonder how long it will be before a hacker figures out how to drop the software remotely? Of course, it also makes sense that FlexiSPY wouldn't want someone to be able to replicate their software. Replicated software doesn't make them any money.

I'll leave it to the reader's imagination how a product like this could be used by criminals, spies, or stalkers.

It never ceases to amaze me how some of these products are sold right over the Internet to ANYONE! It gives credence to the old saying, "there ought to be a law."

FlexiSPY even lists several electronic publications on their site as "talking about them." I decided to see what a few of them (besides F-Secure) had to say.

Gizmodo states:
The software allows a sickening amount of privacy invading features.

Endgaget states:

While FlexiSPY is designed to install itself invisibly, it's now been officially categorized as a trojan (which, face it, it really is) and has been added to F-Secure's virus database.

And the Register states:

A piece of software which allows a user to track another person's mobile phone use would be almost impossible to use in the UK without breaking the law, according to a surveillance law expert.

If fact, using this software could be illegal and subject to penalties in most of the civilized world. Most of these countries would require some sort of court order, even if this technology were to be used by law enforcement.

Gizmodo story, here.

Engadget story, here.

Register story, here.

FlexiSPY acknowledges the same concern that the surveillance law expert brings up in the Register article about them:
It is the responsibility of the user of FlexiSPY to ascertain, and obey, all applicable laws in their country in regard to the use of FlexiSPY for "sneaky purposes". If you are in doubt, consult your local attorney before using FlexiSPY. By downloading and installing FlexiSPY, you represent that FlexiSPY will be used in only a lawful manner. Logging other people's SMS messages & other phone activity or installing FlexiSPY on another person's phone without their knowledge can be considered as an illegal activity in your country. Vervata assumes no liability and is not responsible for any misuse or damage caused by our FlexiSPY. It's final user's responsibility to obey all laws in their country. By purchasing & downloading FlexiSPY, you hereby agree to the above.

I guess the old latin saying "caveat emptor" (buyer beware) applies in this instance!
