Celebrity scandals are always popular and phishers are keen on incorporating them into their phishing sites. Recently, we observed a phishing site featuring British singer and actress Rita Ora. The phishing site was hosted on…
In the last few weeks we have observed a drastic increase in “penny stock” spam emails. In 2011 Symantec published a blog entitled Global Debt Crises News Drives Pump-and-Dump Stock Scams, which also dealt with this type of spam.
Penny stocks, also known as cent stocks, are shares in small companies that trade at low prices, often as low as a few cents per share. Penny stocks are a very popular topic used by spammers. The spam emails advertise the cheap shares and state that the company is on the verge of becoming very successful and that the value of the shares will rise significantly. The emails make out that the company is more valuable than it actually is and implies that they have just created some major product or are on the verge of a breakthrough and that the share value is tipped to rise dramatically. The aim is to increase sales of the stock, which in turn raises the value, then the fraudster can sell their penny stocks for significantly more than they paid for them. This stock fraud method is known as “pump and dump.”
We are seeing various spam methods being used in stock spam such as broken words, obfuscation with irrelevant line spaces, and insertion of randomized characters in the header or body of the emails etc.

Mother’s Day is celebrated in many countries on May 12 and it’s a day for children, regardless of age, to express their love to their mother by giving her a gift. Spam messages related to Mother’s Day have begun flowing into the Symantec Probe Network. Clicking the URL contained in the spam message automatically redirects the recipient to a website containing a bogus Mother’s Day offer upon completion of a fake survey.
Figure 1: Survey spam targeting Mother’s Day
Once the survey is completed, a page is then displayed asking the user to enter their personal information in order to receive the bogus offer.

We recently blogged about the persistence of spam with .pw URLs and not surprisingly a lot of the Mother’s Day spam messages contain .pw top-level domain (TLD) URLs. The following are some examples of the From header using .pw URLs that we have identified to date:
From: Mother’s Day Gifts <Check@[REMOVED].pw>
From: “Early Bird Mother’s Day Flowers” <postmaster@[REMOVED].pw>
From: “Early Bird Mother’s Day Bouquets” <noreply@[REMOVED].pw>
From: “Mother’s Day Bouquets” <MothersDayBouquets@[REMOVED].pw>
From: “Mom” <Mom@[REMOVED].pw>

Last week, Symantec posted a blog on an increase in spam messages with .pw URLs. Since then, spam messages with .pw URLs have begun showing up even more.
Figure 1. .pw TLD spam message increase
Symantec conducted some analysis into where these attacks are coming from in terms of IP spaces. As expected, Symantec observed a large quantity of mail being sent from an IP range and then moving to another IP range. While this is an expected behavior, there was an interesting twist. There were multiple companies (with different names) hosting .pw spammers using the same physical address in Nevada.
Examining messages found in the Global Intelligence Network, Symantec researchers have found that the vast majority of spam messages containing .pw URLs are hit-and-run (also known as snowshoe) spam. The top 25 subject lines from .pw URL spam from May 1, 2013 were:
Subject: For all the moms in your life on Mother’s Day.
Subject: Tax Relief Notification
Subject: Remove IRS Tax Penalties
Subject: Save on the most beautiful bouquets for Mom
Subject: Reusable K Cup for Keurig or single-brew coffee maker
Subject: Garden Today says, “By far the easiest hose to use”
Subject: HOME: Amazingly Strong water hose you can fit anywhere.
Subject: The LAST water hose you’ll ever need

In addition to creating anti-spam filters as needed, Symantec has been in contact with Directi and working with the registrar to report and take down the .pw domains associated with spam. Symantec believes that collaborating with the registrar is a more progressive and holistic approach to solving this problem.
For that past several days, Symantec has observed an increase in spam messages containing hexadecimal obfuscated URLs. Hexadecimal character codes are simply the hexadecimal number to letter representation for the ASCII character set. To a computer, he…
フィッシング詐欺の世界では最近も変わらず、サッカーが大人気のようです。2012 年にも、サッカーを利用したさまざまなフィッシング攻撃が確認されましたが、フィッシング詐欺師は早くも 2014 年の FIFA ワールドカップに熱い視線を注ぎ、有名選手やサッカークラブを狙っています。リオネル・メッシ選手のファンを狙った詐欺や、FC バルセロナを利用した詐欺は、そういったフィッシングの一例です。たくさんのファンが付いている有名選手を利用すれば、標的も膨大な数にのぼり、結果的に個人情報を収集できるチャンスも大きくなることを詐欺師は知っています。2013 年 4 月にもこの傾向は続き、同じようなフィッシング詐欺の手口が横行しています。今回のフィッシングサイトは、フランスにある無料の Web ホスティングサイトを利用していました。
このフィッシングサイトでは Facebook のログイン情報を入力するよう要求します。ページにはリオネル・メッシ選手、FC バルセロナ、あるいはクリスティアーノ・ロナウド選手が目立つようにデザインされています。フィッシングページには彼らの画像が掲載され、いずれかの正規の Facebook ページであるかのような印象を与えます。なかには、「first social networking site in the world（世界で最初のソーシャルネットワークサイト）」というタイトルの偽サイトまでありました。ユーザーは、Facebook ページにアクセスするために Facebook のログイン情報を入力するよう求められます。ログイン情報を入力すると、ログインが有効であると思い込ませるようにリオネル・メッシ選手、FC バルセロナ、またはクリスティアーノ・ロナウド選手の正規のコミュニティページにリダイレクトされます。この手口に乗ってログイン情報を入力したユーザーは、個人情報を盗まれ、なりすまし犯罪に使われてしまいます。
