FaceBook Hack Reveals Trend in Targeting Social Networks

Attacking social networking websites is becoming more common all the time. My guess is that they are being leveraged by criminals, who are after the vast amount of personal information people willingly put up on these sites.

For the past couple of weeks, the ongoing attack on FaceBook has figured prominently in the media. The attack isn't much different than some of the other ones we've seen in recent years – which are to take over a user account – and then use it to trick people into falling for a scam. In this instance, a phishy link is being used to direct the effort.

The intended victim receives a communication from someone they know (who has already been compromised), which directs them to a page that appears to be a FaceBook login. They are then prompted to put in their user name and password. If they do, their information is stolen and will be used to trick even more people into doing the same thing.

Stealing stolen user accounts on eBay has been a problem for years. On eBay, it is a means of using an established seller's credentials to trick people into thinking they are dealing with a "trusted seller." The only difference here is that instead of selling bogus or non-existent merchandise, the intent on FaceBook is probably to trick people into giving up personal or financial information.

This information can then be used to commit financial crimes, using the victim’s identity.

I found some information about the FaceBook attack on Symantec's Security Response blog. Thus far, according to the research conducted on this at their lab, no computers have been infected.

According to Marian Meritt at Symantec, the danger of giving up your FaceBook credentials might go beyond having your account compromised. She believes the hackers behind this are looking to compromise other accounts, where you might use the same credentials. I read some other articles on this and thus far this seems to be the consensus of why the attack is occurring, but no one seems to know for sure.

Whether this is the intent, or not – the advice given in the post is something that should be considered when dealing with the multiple accounts a lot of us have.

First and foremost, you should pay attention to the address in the bar at the top of your page. If it is not exactly the address of the legitimate site, you are probably being tricked into thinking that it is. For instance, www.faceboot.com is not www.facebook.com. Even better, if you spot a suspicious link, hover your mouse on it (without clicking on it) and the actual address will appear at the bottom left-hand of the page. Entering the legitimate address in your address bar is always smarter than clicking on a link, too.

Of course, it's also wise to check out the address at the top of the page after arriving at your destination, also. You should also stop and think when something pops up instructing you to enter your user and password information.

Also recommended is to use complex and unique passwords for each of your accounts, maintain an up-to-date browser and operating system and use updated security software from a reliable vendor.

When purchasing security software, ensure you are not buying counterfeit software or being tricked into purchasing scareware. Scareware is bogus security software that normally prompts a user to run a scan of their system, which reflects all kinds of bad things going on. The problem is that the problems normally do not really exist and the protection they are selling doesn't really protect you, either.

So far as buying counterfeit software, it normally doesn't protect you very well and it might even have some malicious code built right into the program.

While the FaceBook attack is the flavor of the week, it’s not the only social networking site that has been targeted in the recent past. Twitter and MySpace have been the targets of recent attacks, too. SC Magazine did a recent article where a security researcher from Websense was quoted as saying they have detected more than 200,000 sites impersonating the above mentioned social networking sites.

Going beyond social networking sites, financial, auction, e-commerce are frequently attacked, too. The common denominator is sites where criminals can harvest information and turn it into money. Please note that people interested in doing a little bit of due diligence on you personally might see what you are putting up on these sites. I’ve recently seen this presented as a “best practice” when doing background checks on people.

The key is to adopt the known best practices if you enjoy using these sites. Another wise thing to do is to be extremely thoughtful about what information you post on them and how it might be used against you.

Anything you post on these sites can and will be used against you if the wrong person gets their hands on it. In the end, being mindful of the information you are posting on a social networking site is probably the best defense you have. After all, you never know who is looking at it!

Most Internet Scams Start with Spam

I'm sure we've all noticed spam levels are slightly down, or that our spam filters seem to be working a little better. Nevertheless, spam continues to get through filters and for the next few weeks, a lot of it will have a holiday theme. Due to the sour economic situation, it's also likely going to take advantage of financial fears or the promise of a rescue from an already bad situation.

Since most unfortunate situations involving fraud, phishing, and financial misdeeds on the Internet start with a spam e-mail, it pays to use a little common sense and caution before falling for a too good to be true, or sometimes scary e-mail from an unknown source.

Last week, Symantec issued its December 2008 State of Spam Report. It predicts that although spam volumes are down after a lot of providers blocked access to sites hosted by McColo.com, we will likely see them rise again. Spam levels dropped a reported 65 percent after this happened. "McColo.com was allegedly hosting a significant number of botnet command-and-control systems'" according to the report. The bad news is that the report indicates the bad guys are moving elsewhere and that a number of them are hosting their efforts from IP addresses in (where else) China.

Getting back to the holiday season, the report notes that spammers are mimicking marketing come-ons from legitimate retailers offering holiday shopping deals. This makes it hard to distinguish exactly who is behind the e-mail. Sometimes the line between legitimate and illegitimate becomes a little blurry, which is something spammers have always taken advantage of.

The report also reveals a lot of links leading to malware infected sites in spam e-mails are using political themes to draw in their victims. Items related to Barack Obama are especially popular with spammers and scammers. In another twist to using Obama's good name, one spam campaign offered a Barack Obama coin, "a piece of history for only $9.95 plus shipping." This was an attempt to steal debit and credit card information.

Hot news stories were also used as lures to download malicious software. In particular, the recent Mumbai terrorist attacks pointed to links designed to infect machines. Ironically, a lot of this malware is designed to turn a computer into what is referred to as a "zombie," which when used in a botnet is used to send out even more spam.

While we haven't seen the holiday season pass, spammers of the scammer type are already using the IRS name to steal personal and financial information. The pre-tax season phishing scheme mentioned in the Symantec Report involved a come-on designed to snare people by telling them they had a tax refund or economic stimulus payment due to them. The link in these e-mails went to fake IRS site(s) — complete with offical logos — designed to steal personal and financial information.

The IRS isn't alone when it comes to having their good name spoofed. Just this week the FBI reported that their name was being used (yet again) in a campaign involving a typical Nigerian 419 scam. If an intended victim got leery after initially responding — they were threatened with "official consequences" should they fail to turn over the required personal and financial information.

Fear or scaring a victim into submitting to a scam is nothing new. In fact, some of it is now being referred to as Scareware. Scareware most frequently surfaces as a fake message claiming your computer is infected. In then offers to fix the problem for a nominal amount of money. My guess is that malware might actually be downloaded on a system by clicking on one of these come-ons.

Since it's hard to pay in cash over the Internet, anyone who pays on this form of extortion might have their method of payment stolen, also. Symantec recently released another report showing how many personal and financial details are for sale (super-cheap) on the Internet.

Alex Eckelberry of Sunbelt Software and the popular Sunbelt Blog just posted a visual presentation of scareware examples on his Flickr account.

There is little doubt that spam and its intended purposes have made the electronic world somewhat of a "virtual minefield" at times. It pays to make your computer bullet-proof by using good state of the art software from a legitimate vendor, but even if you are protected in this manner, you also need to protect yourself from social engineering schemes designed to lure a person into doing something they are going to regret later.

The Anti Phishing Working Group offers sage advice (from a variety of reputable sources) to the average person on how to avoid becoming a victim. Interestingly enough, they also recently released a report that is rather ominous stating the the number of crimeware spreading URLs are at an all-time high. Crimeware is another name for malware when it has a pure criminal intent.

To close this post, I'll point to a amusing video Symantec did on the 12 Days of Christmas Spam. It's probably best to end on a lighter note on what has become a serious problem.
