イースターは他の祝祭日と同様に歓喜で迎えるべき日ですが、プレゼントやショッピングを楽しみ、お祭り気分の広がる日でもあります。しかし、この祝日に広がるのはお祭り気分だけではありません。スパマーもその手練手管を駆使し始めており、イースターに向けてスパムの件数も急増しています。

シマンテックは毎年、イースターにちなんでさまざまなカテゴリのスパムを確認していますが、今年も例外ではありません。シマンテックがこれまで何年にもわたって確認してきたスパムと、今年見つかったサンプルから、何種類かご紹介します。

模造品スパム
大きな祝祭日にはプレゼントが付きものとあって、商品紹介スパム、特に模造品スパムはシマンテックが確認しているなかでも最も目立つカテゴリです。模造品スパムでは、偽物の高級腕時計や宝石類が、目を引くような件名や商品写真を使って宣伝されています。この手のスパムメールで使われているヘッダーには、次のようなものがあります。

差出人: “WorldOfWatches” <johnwatson@[削除済み]>
件名: Challenge Ends Easter weekend(イースターの週末、今こそチャンス)

差出人: “DailyPromos” <aacpu@[削除済み]>
件名: Our pick today is- easter14(本日の特選品 – Easter14)

医薬品スパム
医薬品スパムも、祝祭日が近づくと増えるスパムカテゴリのひとつです。スパムメールには、処方箋不要で医薬品をオンライン購入できると称する医薬品販売サイトへのリンクが掲載されているのが一般的です。リンク先のサイトでは、季節のあいさつ文をバナーに表示して、お祭り気分を煽っています。

医薬品スパムの下位カテゴリとしては、ダイエット薬スパムもお馴染みで、複数の言語で確認されています。スパムメッセージで宣伝されているダイエット薬は、認可されている医薬品から、外来植物の薬用抽出物と称するものまでさまざまです。この手のスパムメールで使われているヘッダーには、次のようなものがあります。

差出人: “Mackenzie Burns” <monday@[削除済み]>
件名: Begin eating this fruit and lose the fat before Easter Sunday(このフルーツを食べて、今からイースターサンデーまでに脂肪を落とそう)

商品紹介スパム
大手の小売店やブランドショップは、祝祭日に向けてディスカウントやセールを展開しますが、スパマーもそれに便乗しています。スパマーが有名小売店やブランドから発信されたように電子メールを偽装するのは定番ですが、たいていは偽サイトへのリンクが掲載されています。プレゼントのクーポン券進呈を謳う手口も広く使われています。この手のスパムで紹介されている商品は、子供のおもちゃから SUV まで多種多様です。この手のスパムメールで使われているヘッダーには、次のようなものがあります。

件名: Spring Sale Event on all Cars, Trucks, and SUVs!(乗用車からトラック、SUV まで、春の特別セール中!)

差出人: Auto-Dealer-Online <williamw@[削除済み]>

名前入りギフト
最近、名前入りギフトが人気を集めており、イースターエッグやイースターバニーに名前とメッセージを入れられると宣伝するスパムがスパマーの間でも流行しています。ほとんどのスパムメールには偽サイトへのリンクが掲載されていますが、なかには不快なコンテンツにリンクされているものもあります。この手のスパムメールで使われているヘッダーには、次のようなものがあります。

差出人: Easter Bouquets <rebekkahFAjhLg@[削除済み]>
件名: Make the Easter bunny jealous! Easter flowers(イースターバニーに見せつけちゃおう! イースターに花束を)

カジノスパム
オンラインカジノやギャンブルを扱ったスパムも祝祭日に増加します。カジノスパムは、サインアップ特典、報酬ポイント、当選のチャンスなどを餌にして被害者を誘います。この手のスパムメールで使われているヘッダーには、次のようなものがあります。

差出人: AU_AllSlots @ <AllSlots@[削除済み]>
件名: 25-free spins on Gold-Factory this-Easter(今年のイースターに Gold-Factory スロットでコイン 25 枚分を進呈)

419 詐欺スパム
ナイジェリアスパムは、宝くじの当選金や寄付金などを餌にして、どの祝祭日にも決まって登場します。シマンテックは、孤児院や慈善団体を詐称して不幸な子供への寄付金を募る 419 スパムを確認しています。個人情報を求めてくる迷惑メールは、常に慎重に扱う必要があります。この手のスパムメールで使われているヘッダーには、次のようなものがあります。

差出人: suzanne122@[削除済み]
件名: HappyEasterInAdvance,(一足早くハッピーイースター)

その他に今年シマンテックが注目したのは、外国語のイースタースパムの件数です。外国語でイースターにちなんだスパム攻撃は、その多くがプレゼントや商品の紹介であり、カップケーキやジンジャーブレッドの宅配スパムなどが確認されています。

ポルトガル語
差出人: “Cupcake” <contato@[削除済み]>
件名: Páscoa                                                          | 件名: Easter(イースター)

ロシア語
差出人: Пасхи <vamdetal@[削除済み]>                     | 差出人: pasha
件名: Скоро Пасха                                                  | 件名: Almost Pasha(もうすぐイースター)

差出人: Пряники <sladkie.pashi@[削除済み]>           | 差出人: Gingerbread
件名: Кондитерская мастерская                              | 件名: Confectionery masterskaâ(お菓子工房)

シマンテックも、皆さまが素敵なイースターをお過ごしになれるようお祈りしたいと思いますが、こうしたスパム攻撃には十分にご注意ください。祝祭日を悪用した迷惑メールや予期しない電子メールには常に警戒が必要です。疑わしいメールに掲載されているリンクはクリックしないようにしてください。また、スパム対策シグネチャを忘れずに更新して個人情報を保護したうえで、楽しいイースターのひとときを安心してお過ごしください。

Prepare-se para os Spams durante a Páscoa

A Páscoa, como muitas outras datas comemorativas, deveria significar um dia de alegria, o que obviamente remete a presentes, compras e festas. Porém, essa animação não é a única coisa que está sendo espalhada neste feriado. Os Spammers também começaram a difundir seu trabalho vicioso. A poucos dias da Páscoa, o volume de Spams cresceu significativamente.

A cada ano que passa, a Symantec observa certas categorias de Spam utilizando a Páscoa como tema central e este ano não foi diferente. Vamos ver abaixo alguns dos diferentes tipos de Spam que a Symantec coleta ano após ano bem como alguns exemplos coletados este ano.

Spams de Bens de Consumos

Com presentes sendo o item mais importante de qualquer data comemorativa, Spam de produtos (especialmente bens de consumo) é a categoria de Spam que a Symantec mais observa. Nesse tipo de Spam, itens como relógios e joias falsificadas  são promovidos usando slogans e belas imagens de produtos. O cabeçalho do e-mail inclui exemplos como:

De: “WorldOfWatches” <johnwatson@[REMOVED]>

Assunto: Desafio termina no fim de semana de Páscoa

De: “DailyPromos” <aacpu@[REMOVED]>

Assunto: Nossa sugestão hoje para a Páscoa 2014

Spams Médicos e Farmacêuticos

Spams de remédios e farmácias são outra categoria de Spam que vemos muito quando chegamos perto das datas comemorativas. Esses Spams normalmente contém algum link para sites de farmácias que fingem vender medicações online sem a necessidade de receitas médicas. Esses sites normalmente exibem banners festivos para criar um clima mais realista.

Spams específicos para quem quer perder peso são uma subcategoria dos Spams médicos que são vistos em muitas línguas diferentes. Medicações para perda de peso exibidas nessas mensagens variam de medicações reconhecidas pelo mercado bem como extratos de ervas e plantas exóticas. O cabeçalho do e-mail inclui exemplos como:

De: “Mackenzie Burns” <monday@REMOVED>

Assunto: Começe a comer essa fruta diariamente e perca gordura antes da páscoa!

Spams de Produtos

Grandes lojas de varejo e marcas oferecem inúmeros descontos e promoções durante as datas comemorativas e os Spammers se aproveitam disso. Spammers geralmente constroem seus E-mails para que pareçam vir de conhecidas marcas e lojas de varejo, mas normalmente eles possuem links redirecionando para sites falsos. Ofertas para cupons de presentes também são muito comuns. Os produtos vistos nesse tipo de Spam variam desde brinquedos até Veículos. O cabeçalho do e-mail inclui exemplos como:

De: Auto-Dealer-Online <williamw@[REMOVED]>

Assunto: Promoção de Outono para todos os carros, Jipes, Caminhonetes e SUVs

Spam de Presentes Personalizados

Presentes e lembranças personalizadas também estão ficando populares este ano e Spams promovendo mensagens personalizadas em ovos de páscoa e coelhinhos da páscoa está se mostrando popular entre os Spammers. A maioria desses Spams possuem links para sites falsos e alguns deles redirecionam o usuário a sites com conteúdo inapropriado.  O cabeçalho do e-mail inclui exemplos como:

De: Easter Bouquets <rebekkahFAjhLg@[REMOVED]>

Assunto: Deixe o coelhinho da Páscoa com inveja! Flores de Páscoa!

Spam de Cassinos

Jogos online e Spams de cassinos aparecem em grande volume durante a época das datas comemorativas. Spams de cassinos provocam as vítimas com bônus na inscrição, recompensas em pontos e chances de ganharem fortunas. O cabeçalho do E-mail inclui exemplos como:

De: <suzanne122@[REMOVED]>

Assunto: Nessa páscoa, jogue gratuitamente no Cassino Gold Factory

Spam de Fraudes

Spams de fraudes monetárias rotinamente dão as caras durante essa época do ano. A Symantec observou muitos Spams fingindo serem de orfanatos ou instituições de caridade buscando doações para os menos afortunados. E-mails desconhecidos pedindo informações pessoais sempre deveriam ser tratados com cuidado. O cabeçalho do E-mail inclui exemplos como:

Português

De: <suzanne122@[REMOVED]>

Assunto: Feliz páscoa adiantado

Outra coisa que nos chamou a atenção esse ano foi o alto volume de Spams de páscoa em outras línguas. O ataque de Páscoa normalmente contém presentes e brindes, como o Spam de entrega de Cupcakes e Ovos de Páscoa mostrados aqui:

Russo

From: Пасхи <vamdetal@[REMOVED]>                   | From: pasha

Subject: Скоро Пасха                                                | Subject: Almost Pasha

From: Пряники <sladkie.pashi@[REMOVED]>         | From: Gingerbread

Subject: Кондитерская мастерская                      | Subject: Confectionery masterskaâ

A Symantec deseja um Feliz Páscoa para todos os seus usuários e também aconselha muito cuidado com essas campanhas de Spams. Sempre tenha atenção com e-mails desconhecidos ou inesperados. Nunca clique em links de e-mails que pareçam suspeitos. Lembre sempre de manter seus softwares de segurança atualizados para lhe proteger e poder lhe fornecer a paz de espírito para comemorar e celebrar uma maravilhosa Páscoa.

Expect Beautifully Packaged Spam along with Your Easter Gifts!

Contributor: Azam Raza

Easter, like all other celebrations is meant to be a day of jubilation, which of course means gifts, shopping, and spreading cheer. However, cheer is not the only thing that is being spread this holiday. Spammers have also started spreading their handiwork. With just a few days left before Easter, the volume of spam is on the rise.

Each year Symantec observes certain categories of spam using Easter as a theme and this year is no different. Let’s take a look at some of the different types of spam Symantec sees year-over-year, as well as some samples from this year.

Replica goods spam
With gifts being at the core of many major celebrations, product spam (replica goods spam in particular) is the spam category Symantec observes the most. In this spam, items such as fake watches and jewelry are promoted using catchy subject lines and product images. Email header examples include:

From: “WorldOfWatches” <johnwatson@[REMOVED]>

Subject: Challenge Ends Easter weekend

From: “DailyPromos” <aacpu@[REMOVED]>
Subject: Our pick today is- easter14

Health spam
Pharmacy or medication spam is another spam category we see a lot of when we get close to any holiday season. These spam mails usually contain links to pharmacy sites which pretend to sell medication online without prescription. Season’s greetings are usually displayed as banners on these sites to add a festive touch.

Weight loss spam is another subcategory of health spam which is seen in multiple languages. Weight loss medicines touted in these messages range from approved medication to stories about herbal extracts from exotic plants. Email header examples include:

From: “Mackenzie Burns” <monday@[REMOVED]>

Subject: Begin eating this fruit and lose the fat before Easter Sunday

Product spam
Major retailers and brands offer large discounts and sales during holiday celebrations and spammers take advantage of this. Spammers often craft their emails to make them appear to be from known retailers and brands but they usually include links leading to fake sites. Offers of gift coupons are also common. The products seen in this type of spam can range from kids toys to SUVs. Email header examples include:

Subject: Spring Sale Event on all Cars, Trucks, and SUVs!

From: Auto-Dealer-Online <williamw@[REMOVED]>

Personalized gifts
Personalized gifts are getting popular these days and spam promoting personalized messages on Easter eggs and Easter bunnies are proving popular among spammers. Most of these spam mails have links to fake sites and some of them even have links to inappropriate content. Email header examples include:

From: Easter Bouquets <rebekkahFAjhLg@[REMOVED]>

Subject: Make the Easter bunny jealous! Easter flowers

Casino spam
Online casino and gambling spam show up in larger volumes during holiday periods. Casino spam entices victims with a signup bonus, reward points, and chances of winning a fortune. Email header examples include:

From: AU_AllSlots @ <AllSlots@[REMOVED]>

Subject: 25-free spins on Gold-Factory this-Easter  

419 scam spam
Nigerian spam routinely makes the rounds during all holiday festivals with news of lucky draws and donations. Symantec has observed 419 spam pretending to be from orphanages and charity organizations asking for donations for the unfortunate. Unsolicited emails asking for personal information should always be treated with caution. Examples of email headers include:

Subject: HappyEasterInAdvance,

From: suzanne122@[REMOVED]

Something else which caught our attention this year is the volume of Easter spam in foreign languages. Easter themed attacks in foreign languages are usually about gifts and goodies, like the cupcake and gingerbread delivery spam shown here:

Portuguese

Subject: Páscoa                                                             |Subject: Easter

From: “Cupcake” <contato@[REMOVED]>

Russian

From: Пасхи <vamdetal@[REMOVED]>                       | From: pasha

Subject: Скоро Пасха                                                    | Subject: Almost Pasha

From: Пряники <sladkie.pashi@[REMOVED]>             | From: Gingerbread

Subject: Кондитерская мастерская                              | Subject: Confectionery masterskaâ

Symantec wishes all our customers a very happy Easter, and we also advise you to be cautious of these spam campaigns. Always exercise caution when dealing with unsolicited or unexpected holiday themed emails. Do not click on links in emails that look suspicious. Remember to update your antispam signatures to safeguard your personal information and give you the peace of mind to celebrate the wonderful Easter celebrations.
