Spam

Crime traditionally increases during the holiday season, and cybercrime is no different. The malware writers, spammers and scammers are out in force. They’ve recently hit “Odnoklassniki” with this message: “Hi! I’ve got a New year surprise for you [emoticon] send 2133 279 (must be with a space) to 4460 and you’ll be pleasantly surprised! If you don’t take a look, I’ll be very grouchy with you [emoticon]” This message is clearly designed to make the bad guys a bit of holiday cash: an SMS sent to the number given in the message costs between $5 and $12 dollars, depending on the mobile service provider. ...

Well, it didn’t take long for the Christmas E-Card scams to start. Recently we have seen email messages pretending to be from Hallmark, suggesting that you have received an E-card from a friend. The complete email message looks like this:You have recieved a Hallmark E-Card from your friend. To see it, check the link below: http://www.hallmark.com/webapp/wcs/stores/Occasion/ChristmasE-CardsThere’s something special about that E-Card feeling. We invite you to make a friend’s day and send one.Hope to see you soon, Your friends at Hallmark ...

Almost the entire year 2009, the battle for the first place on phishing targets took place between Ebay and Chase Bank. Most of the time, the Chase Bank was on top of the most phished brands. In December, the situation was changed: Now PayPal is the most phished brand (32205 unique URLs) followed from far away by the Chase Bank (25901 unique URLs) and Ebay (18738 unique URLs). ...

As was announced on Dec 11th, CNNIC (China Internet Network Information Center) now requires a “formal paper based application material when making the online application to the registrar.” The motivation behind this seems more related to cracking down on porn sites, but since .cn domains have been the call-to-action in 35-50% of all spam being sent for well over a year, we were wondering what effect this policy change may have on the prevalence of this TLD in spam. The graph below illustrates the percentage of spam messages sent each day that contain a .cn domain (vast majority are Canadian Pharmacy type spam) as well as the percentage of pharmacy spam messages sent that contain a link to a free webhosting service (blue). I decided to measure the .cn abuse, against free webhosting abuse, as the same Canadian Pharmacy spam that contained links to .cn domains for the past few months, now contain links to a number of free webhosting services instead. The CNNIC changes started to be applied on December 14th. ...

Starting at ~3:20pm GMT today, Canadian Pharmacy spammers began using attached MP3 files as the call-to-action for their latest campaign. The message had no subject, no “text” body content, just an attached “audio/mpeg” file with a random lower case file name. Upon playing the attached mp3 file, you find out why I called it the “call-to-action”. A robotic sounding woman’s voice reads off the URL they would like recipients to browse to (letter by letter), with porn-like moaning as background noise. I guess they are going for the often used spam tactic of tying ED pills (Viagra, Cialis, etc..) to porn star-like performance in bed. ...

It’s not a huge surprise that we are seeing some malware spam runs where the malicious attachment attempts to portray itself as a Christmas Greeting of some sort. Here’s an example from today (md5: C670165AE6DFA8318F0EA795B1D3AD55). This one is actually a Zapchast (IRC bot variant). The “Christmas Card” requires it’s own “special version” of Flash to be installed — flashplayer2009.exe — which is the malware itself. Once ready, it will display this friendly message written in Universal Gibberish. ...

Email is still the most common method used for security update notifications from all major vendors, but it is also the most commonly used trigger for launching the chain of infection attacks by malware writers. When I came to work today I found in my Inbox a message from Microsoft with the Security Bulletin Advance Notification for December. I immediately clicked on one of the links to visit the yet to be published December Security Bulletin and investigate how many critical vulnerabilities will be fixed this month. ...

According to the 2002 Census of the Population, 42% of the population of Ireland has the ability to speak Irish. Irish has also had official and working language status at the EU level since January 1, 2007. Recently, some examples of spam messages in Irish—the official language of the Republic of Ireland—have been observed. While the Irish translation is generally pretty good in this example, there are some anomalies between how certain phrases have been constructed. For example: ...

We recently alerted our readers to spam campaigns using the H1N1 vaccination program to prompt recipients to open the mail. And we have frequently mentioned that crooks love to take advantage of news, disasters, and other events. Now that the final draw for the FIFA World Cup in South Africa next year has taken place, it is time to remind you that sports events are no exception to the rule. I’ve already found some examples. The first is a fake lottery. In this case, the source claims the recipient has won a large sum of money from the South African Football Association. After contacting the lottery manager, the victim of the scam will be asked to pay “processing fees” or “transfer charges” so that the winnings can be distributed. Don’t expect to ever see a payment. ...

The original 2009 version of this checklist recommended Symantec Brightmail and the Symantec State of Spam site. Brightmail is now part of Broadcom’s enterprise portfolio and is not a practical choice for home users. The do/don’t advice below is still sound. Do Unsubscribe from legitimate mailings that you no longer want to receive. When signing up to receive mail, verify what additional items you are opting into at the same time. De-select items you do not want to receive. Be selective about the Web sites where you register your email address. Avoid publishing your email address on the Internet. Consider alternate options — for example, use a separate address when signing up for mailing lists, get multiple addresses for multiple purposes, or look into disposable address services. Using directions provided by your mail administrators, report missed spam if you have an option to do so. Delete all spam. Avoid clicking on suspicious links in email or IM messages as these may be links to spoofed websites. We suggest typing web addresses directly in to the browser rather than relying upon links within your messages. Always be sure that your operating system is up-to-date with the latest updates, and employ a comprehensive security suite. For organizations, use a reputable e-mail security gateway (Microsoft Defender for Office 365, Google Workspace spam filtering, or a dedicated provider such as Proofpoint or Mimecast) to filter spam before it reaches inboxes. Keep up to date on recent spam trends — the Anti-Phishing Working Group publishes quarterly reports on phishing and spam activity. Do not Open unknown email attachments. These attachments could infect your computer. Reply to spam. Typically the sender’s email address is forged, and replying may only result in more spam. Fill out forms in messages that ask for personal or financial information or passwords. A reputable company is unlikely to ask for your personal details via email. When in doubt, contact the company in question via an independent, trusted mechanism, such as a verified telephone number, or a known Internet address that you type into a new browser window (do not click or cut and paste from a link in the message). Buy products or services from spam messages. Open spam messages. Forward any virus warnings that you receive through email. These are often hoaxes.
