聖パトリックの日は、アイルランドの文化と宗教にとって重要な祝日であり、3 月 17 日に世界各地で祝われますが、特にアイルランド人のコミュニティや組織にとっては大きな意味を持っています。最近、聖パトリックの日に関連するスパムメッセージが、Symantec Probe Network に多数届いていることが確認されています。確認されたスパムサンプルの多くは、車の在庫一掃セールをはじめとして、お買い得商品を宣伝するものです。

興味深いのは、この祝日の名前を、大容量ファイルの送受信に利用できる有名サイトと関連付けて騙そうとするスパムメールが確認されていることです。リンクをクリックすると、悪質なコードをダウンロードする Web ページにリダイレクトされます。このページでは、狙われやすい脆弱性がいくつか悪用されています。これらのスパム活動の主な目的は、電子メールの件名や本文で聖パトリックの日を利用してユーザーを誘うことにあります。「Patrick[RANDOM NUMBERS](パトリック[ランダムな数])」といった件名が一例ですが、このような手口には注意して、リンクはクリックしないようにしてください。

型式と車種を選ぶと、さらに別の Web ページにリダイレクトされ、今度は住所や電子メールアドレス、支払方法などの個人情報を入力する画面が表示されます。これは明らかに個人情報を盗み出そうとする手口であり、注意が必要です。

次に示すスパムメールのサンプルは、偽の広告でユーザーを煽って商品を購入させようとしています。URL をクリックすると、医薬品販売を騙る偽の Web サイトにリダイレクトされます。

Much More Than a Free 50 Pound Bet

      No Comments on Much More Than a Free 50 Pound Bet

Contributor: Vivek Krishnamurthi

The Cheltenham Festival, also known as the National Hunt Meeting, is a popular horse racing event that occurs every year in March in the United Kingdom. The festival usually coincides with Saint Patrick’s Day. This year, the festival is currently in progress and will end on March 15. A large amount of gambling takes place during the Cheltenham Festival, a fact that spammers seem to be well aware of as we are presently observing an increase in online gambling spam.

One particular sample of spam included instructions on how to register a free bet. The link provided in the message directs the user to a form where they can sign up and get a free bet worth up to £50.

Some of the email header information found in this spam campaign includes the following:

  • Subject: Bet on Cheltenham with the Best Odds!
  • From: Cheltenham Festival Bets <xxx@BestWorldOnlinexxx.com>
  • From: xxxCheltenham Festival Betsxxx“ <xxx.@x.greatnewoffersxxx.com>
  • From: xxxCheltenham Festival Betsxxx“ <xxx.@x.ExcellentDealsOnlinexxx.com>

Figure. Cheltenham Festival gambling spam
 

Once the user registers, their personal details are in the hands of the spammers. This situation can be even more alarming if the user shares their banking details. Beware of any fake betting offers from such sites; the reality is you are partaking in much more than a free bet of £50.

Symantec also advises our readers to be cautious when handling any unsolicited or unexpected emails. We are keeping a close eye on spam related to the Cheltenham Festival event, and another upcoming festival—Saint Patrick’s Day.

Spammers Special Feast for St. Patrick’s Day

St. Patrick’s Day is a global celebration of Irish culture and a religious holiday on March 17, and it is very special to Irish communities and organizations. Recently, we have observed numerous St. Patrick’s Day related spam messages flowing into the Symantec Probe Network. Many of the spam samples observed are encouraging users to take advantage of clearance sales of cars as well as other product offers.

Interestingly, in one spam campaign, we observed a malicious spam email that tries to trick users by using the name of the event in conjunction with a popular site that allows users to send and receive large files. By clicking on the link, the user is redirected to a Web page that downloads some malicious code, which exploits several common vulnerabilities. The main motive of these spam campaigns is to lure recipients by taking advantage of the St. Patrick’s day holiday in the subject line and body of the email, such as: “Patrick[RANDOM NUMBERS]”. In such cases, users should be careful and avoid clicking on the links.

The spam may lead to a website declaring a clearance sale on St. Patrick’s day.

Figure2. Financial spam targeting St. Patrick’s Day

When the user clicks on the “Get Prices Button” for the clearance prices of cars, they get redirected to another Web page that asks them to select the type of car model for a price comparison.

After entering the make and model of the car, the user gets redirected to another Web page asking for their personal details, including their address, email address, and payment details. Users should be wary of such information-stealing attempts by spammers.

Figure4. Asking the user for their personal information

Below are some of the subject lines that we have observed regarding the clearance sale spam attacks for St. Patrick’s Day:

  • /*St. Patrick’s Day clearance, test drive your new car… .* */
  • See Clearance Prices on all XXX Vehicles on St Patrick
  • St Patrick’ XXX Clearance
  • See Clearance Prices on all XXX Vehicles on St Patrick’s
  • 2013 St Patrick XXX Huge Discount – Slashing prices to meet Quotas

The following example is from a spam email that encourages users to take advantage of bogus offers and purchase products. By clicking the URL, the user is re-directed to a fake pharmaceuticals website.

Symantec advises our readers to be cautious when handling unsolicited or unexpected emails. We at Symantec are monitoring spam attacks 24×7 to ensure that readers are kept up-to-date with information on the latest threats.

Have a great St. Patrick’s Day!
