Hide Notes 

Slide 1: November 2009 In October 2009, spam volumes made up 87 percent of all email messages. The most notable highlight this month is the growth of spam originating from APJ (23 percent) and South America (22 percent), with a corresponding decline in spam originating from EMEA (28 percent) and North America (20 percent). With respect to spam categories, Internet spam increased by 7 percent and now accounts for 39 percent of all spam messages. This category includes degree spam, which this month dominates the top 50 spam subject lines. The following trends are highlighted in the November 2009 report:  EMEA’s Position as the King of Spam is Threatened by New Princes  Malware as A Percentage of Spam Continues to Increase  Users of Social Networking Websites Face Malware and Phishing Attacks  October 2009: Spam Subject Line Analysis  Instant Degrees Dominate Spam Subject Lines in October 2009  One Holiday spam Campaign Makes Way for Another Report #35 Spam Percentage: The model used to calculate spam percentage now factors in network layer blocking in addition to SMTP layer filtering, and as a result represents a more accurate view into the actual spam percentage on the Internet.

Slide 2: EMEA’s Position as the King of Spam is Threatened by New Princes In the February 2008 State of Spam Report , Europe was crowned the new king of spam as approximately 44 percent of all spam claimed to originate there, versus 35.1 percent which claimed to originate from North America. In October 2009, it seems that EMEA’s position has been threatened by the Asia Pacific and Japan (APJ) region and South America. In October 2009 we monitored the following:  The EMEA region continues to retain the mantle as primary region of origin for spam at 28 percent. This is a six percent decrease from June 2009.  APJ and South America have now passed North America with 23 percent, and 22 percent respectively of all spam originating from these regions. Twenty percent of all spam now originates from North America —a five percent decrease since June 2009. This sizeable increase in spam appearing from South America and the APJ region is significant, but not altogether surprising when you consider the massive growth of Internet connections in these regions during the past few years. Other factors at play here include:
Slide 3: EMEA’s Position as the King of Spam is Threatened by New Princes     Spam levels have increased dramatically since February 2008. In that month’s report, spam levels reached 78.5 percent of all email traffic during January 2008. This contrasts sharply with what was observed in October 2009 as spam levels hit a maximum of 93 percent, and averaged at 87 percent of all email messages. Distribution networks are becoming more dynamic as additional broadband connected targets are coming online every day. Distribution paths are also getting more complicated with spammers now sending messages directly from infected machines, routing through compromised relays and continuing to use webmail/SMTP Auth abuse. Botnets continue to jockey for position after shutdowns such as McColo. The number of botnets is set to grow as hackers target developing IT infrastructures in certain regions such as APJ and South America. When the country ranking for origin of spam for June 2009 is compared with October 2009, it can be seen that countries such as India, Taiwan, Thailand and Chile have increased several places. Vietnam jumped 13 spot and is now the third most spamming country.  Finally, it should be noted that the nature of spam and its distribution on the Internet presents challenges in identifying the location of the people sending the messages. Many spammers redirect attention away from their actual geographic location.
Slide 4: Malware as A Percentage of Spam Continues to Increase In October 2009, an average of 1.9 percent of all spam messages contained malware. This equates to a 0.6 percent increase from September 2009 when the number of messages containing malware hit a maximum of 4.5 percent of all spam. As reported in the October 2009 State of Spam Report, this increase in malware is significant when you consider that 87 percent of all email messages in October 2009 were spam and the increased message size of spam emails email that have attached malware may also be significant.
Slide 5: Malware as A Percentage of Spam Continues to Increase One of the more interesting spam emails that had malware attached to it was masquerading as a notification from Facebook that the recipient’s password has been reset. The message contained an attached zip file containing a malicious exe file. Symantec detects the exe files as Trojan.Bredolab. This variant of Bredolab connects to a Russian domain and the infected machine is most likely becoming part of a Bredolab botnet.
Slide 6: Users of Social Networking Websites Face Malware and Phishing Attacks In addition to the malware related spam attack targeting Facebook in October, Symantec has observed a phishing attack targeting Facebook. The messages look like an official Facebook invite or password reset confirmation mail. If the cursor is placed over the update button in the message, the phishing URL can be observed. The user may then be redirected to a Facebook look-alike phishing site where they are asked to enter their password to complete the update procedure. Unfortunately, the user’s password will be stolen if they try to login on this page. These attacks can be identified by the subject lines listed below: Facebook account update New login system Facebook Update tool As spammers continue to hide behind the reputation of legitimate senders, social networking sites which have a large user base will continue to be targets of malicious and phishing emails.
Slide 7: October 2009: Spam Subject Line Analysis In the October 2009 State of Spam Report , the top ten subject lines used by spammers were dominated by a mixture of malware related attacks and NDR bounce spam subject lines. NDR bounce spam averaged at 4.54 percent of all spam while spam messages containing malware averaged at 1.9 percent of all spam messages.

Slide 8: Instant Degrees Dominate Spam Subject Lines in October 2009 Instant degree spam attacks have become one of the most high profile attacks observed in recent months. These messages try to entice users with degrees in policing, nursing, teaching and the culinary arts. These attacks often offer instant degrees, with no effort required – just call the number provided in the message and users may obtain a degree certificate in no time. Sample image of these messages: With the increased popularity of online education, spammers are once again tapping into a high profile market. In October 2009, degree spam dominated 22 out of the top 50 subject lines observed related to this attack.
Slide 9: One Holiday Spam Campaign Makes Way for Another With the Halloween spam campaigns set aside for another year, it is time for the Thanksgiving, Christmas and New Year spam campaigns to take center stage. Earlier this year, Symantec reported that spam campaigns targeting end of year holidays, such as Christmas, began in August. Observations from the 2008 spam holiday season included:  As legitimate mailers sent out more and more mailings with special “deals” and “offers” (as observed in the run up to Cyber Monday and Black Friday of 2008) to try and sell their products during the difficult economic time, spammers also used subject lines that tried to draw users in by saving money.  Similar seasonal subject lines were often used in both spam and legitimate mailings. Spammers used these subject lines to try and evade some antispam filters.  Seasonal spam subject lines often did not use randomization or other obfuscation techniques. The top ten seasonal spam subject lines observed between October and November 2008 include the following: 1. Best Sales 2008! 2. Spend less this Christmas 3. A Really Good Gift 4. Christmas Specials 5. Christmas promo few days left 6. Gifts for Christmas 7. Holiday Luxury Gifts 8. Hot Christmas Specials 9. Most Affordable Gifts 10. Low Christmas Pricing Examples of holiday-themed spam campaigns observed so far this year are listed below:

Slide 11: Checklist: Protecting your business, your employees and your customers 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. Deselect 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.

Consider a reputable antispam solution to handle filtering across your entire organization such as Symantec Brightmail messaging security family of solutions. Keep up to date on recent spam trends by visiting the Symantec State of Spam site which is located here. 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.
