Thanks to Shravan Shashikant and the Norton Confidential Online team for providing the data, and to Christopher Mendes for compiling it.

Does phish taste better than spam? Yes, perhaps it does. Allow me to explain.

The recent past has been one of the most volatile financial periods in history. World economies have reached a very critical stage—sovereign debt crises, bailouts, loan defaulters causing banks to shiver, sales shrinkages causing trade surplus, and bankruptcies. Add to all of this the fears of a double-dip economic recession theory making the rounds and it looks like a really dreadful picture.

But how does this affect the consumer from the point of view of email security? The consumer is the fulcrum point, the hinge of the story! All these negatives hits consumer spending in a very big way. The first wave of recession had definitely dented consumer confidence, and with the “Double Dip” theory lurking on the horizon it...

Thanks to Anand Muralidharan for contributing to this blog.

Recently there was a serious bomb blast outside the high court in Delhi, the capital of India. The blast happened on September 7, 2011, and the investigations are continuing with the National Investigation Agency (NIA). News of this terrifying event is being used by spammers to promote fake pharmaceutical products. In the past we’ve seen Mumbai terror attack news used by spammers for advertising pills—we blogged about it in Spammers Attempting to Cash in on Mumbai Terror.

Below are some spam subject samples:

Subject: Delhi explosion
Subject: Bombing at Delhi court kills 10

The domains that are included with these latest spam messages lead users to fake online pharmacies. Using domain names...

Thanks to Vivek Krishnamurthi for contributing to this blog.

Every sensitive event is an opportunity to exploit. With this motive in the background, it is not surprising to see spammers exploit 9/11.  With the 10th anniversary of the tragedy just a day away, spammers want to make the best use of this emotionally charged environment. 

Here are two examples of scams that Symantec has noticed in recent days that attempt to exploit the emotional scars left by 9/11:
 
First email example exploiting 9/11
Figure 1: First email example exploiting 9/11
 
 
Second email example exploiting 9/11
Figure 2: Second email example exploiting 9/11
 
The first sample tries to entice...

Thanks to Amit Kulkarni for his contributions to this blog.

Since its launch, the Apple iPhone has been on the wish lists of most consumers.  The iPhone 4 has already made an impression in the marketplace, so it is obvious that spammers will make the best of this opportunity.  Symantec observed spam tactics just before the release of iPhone 4 and is expecting an even greater spam volume when iPhone 5 is released to the market.

The next generation of iPhone is expected to hit the market in September and spammers don’t want people to wait until the official release. Below is a sample of spammer hype campaigning to lure people into their trap. As usual, the bait is a survey one has to complete to be eligible to own “this coveted piece of art!”

Thanks to the co-author of this blog, Wahengbam RobinSingh.

Phishers are constantly looking for new ideas in their efforts of tricking end users. In August, Symantec observed a phishing site that utilized a number of new tricks. The phishing site masqueraded as a well known software company and claimed to offer associated software products at discounted rates. The phishing page highlighted these fake offers as “summer offerings” and stated that customers could save 80% on their purchases. Users were prompted to enter their billing information, personal information, and credit card details to complete their purchases. The personal information that was requested consisted of the user’s email address and phone number. The credit card details that were asked for were the card number, CVV code, and card expiration date. If any users had fallen victim to the phishing site, the phishers would have successfully stolen their confidential information for...

The five-time Grammy award winner Amy Winehouse was found dead in London on July 23rd. Symantec has already observed spammers who are trying to capitalize on related news headlines by sending out malicious threats less than a day after the news was released.

The two samples given below are examples that we have observed. These Portuguese-language attacks use similar spam techniques. All samples are sent from randomized individual email accounts with various subject lines related to the celebrity’s death in an attempt to lure interested readers to open a malicious URL. Immediately after the link is clicked, a pop-up window is shown, which asks users to download a file that is loosely disguised as an image or video file, for example (anything other than an executable).

The file is given a name that is related to the celebrity, and of course isn’t an image or video file, but a malicious binary. Symantec has detected the threats in these samples as...

Apple's MobileMe is a collection of online services and software. Among its various services is a file-hosting service called iDisk. Recently, Symantec has recorded phishing sites that spoofed iDisk’s Web page. The phishing sites were hosted on a free Web-hosting site.

So, what’s in this service that interests phishers? The service is based on a paid subscription, with which files of up to 20 GB can be uploaded and shared. Phishers are looking to gain access to this service for free. This is an example of a phishing attack targeting user information for reasons other than financial gain.

The phishing site prompts the user to enter their password for logging in. (In this case, the user ID was already populated on the phishing page.) After the password is entered, the page redirects to the legitimate Web page of Apple MobileMe with an error message for an invalid...

It’s been a week since the 2011 edition of the oldest international soccer tournament in the world began, held this year in Argentina. I’m talking about the Copa America. This event is hosted by a South American country every three or four years during the summertime and lasts almost a month. Some say that this tournament is the American equivalent of the UEFA Euro Cup.

South American families and friends hang out together to enjoy the games, and users look for news and the latest results over the Internet. Just as with other important sporting competitions, Symantec has been observing spammers taking advantage of this event to announce multiple unsolicited offers and discounts that are purportedly linked to the soccer tournament.

The spam sample below invites users to visit a Web page that is offering medical equipment. The site also offers more products and discounts that are valid only during the tournament time.

We have recently observed a run of spam that is trying to capitalize on the new social networking platform provided by Google, named Google+. The spam samples are similar to other social network spam messages, which are discussed in one of our previous blogs. Currently, Google is trialing their new venture with limited users; therefore, participation is by invitation only. Hence, it is expected that we’ll see bogus Google+ invites distributed as spam in the wild.

The message in this latest spam campaign looks like a legitimate invite from an already registered user, and it provides an invitation link. However, if one takes even a cursory glance at the URL in the status bar, it shows that the link doesn’t relate to Google in any way.
The headers in the spam samples are as follows:

Subject: Welcome to the Google+ project
From: [removed] (Google+) <[removed...

He was seen several years ago. Now, he is back with the name “Don Gunshot”!

Luring people with promises of huge sums of money in return for bogus favors is the classic method adopted by the Nigerian/419 type of spammers. It is one of the oldest forms of spamming; very rudimentary, yet creatively lethal. This revisited scam tactic uses coercion to force people to pay up or else they will (apparently) face dire consequences. From a lighter point of view, however, it is a bit more humorous than scary.


 
The above email is indeed a perfect example of a scammer trying to blackmail someone they don’t know from Adam. The spammer does not know you, but he pretends to have received blood money to kill you. He blackmails you with threats of dire consequences if you even try to whisper the secrets explained in the mail. Forget the police, and if you dare to try and tell...
