Com a renúncia de Bento XVI e da eleição do novo pontífice da Igreja Católica, Francisco I, nas últimas semanas o Vaticano tem aparecido nos principais noticiários. O interesse gerado por este tema tem chamado atenção dos spammers, que aproveitam o momento para espalhar malware na web.
O Symantec Security Response tem observado que atacantes estão distribuindo spams que direcionam os usuários a um site que hospeda o ‘Kit Exploit Blackhole’. A boa notícia é que a Symantec já oferece proteção para esta ameaça.
A mensagem maliciosa afirma ser de um canal de notícias bem conhecido. As seguintes linhas de assunto são usadas neste ataque:
Assunto: Opinião: O novo Papa Bento pode ser processado por casos de abuso sexual? – [REMOVIDO]
Assunto: Opinião: Novo papa e autoridades do Vaticano processados por suposto abuso sexual! – [REMOVIDO]
Assunto: Opinião: Novo Papa processado por não usar cinto de segurança no Papamóvel … – [REMOVIDO]
Os domínios utilizados no e-mail foram recentemente registados. Ao clicar no link da mensagem, o usuário é direcionado para um site malicioso que hospeda o malware. A imagem seguinte é uma captura de tela do e-mail malicioso (em inglês):
Abusar da popularidade de uma agência de notícias conhecida aumenta as chances de um ataque bem sucedido. No entanto, a Symantec oferece proteção multinível adequada contra essa ameaça. As recomendações dos especialistas da companhia são não abrir e-mails não solicitados e manter o software de segurança atualizado, a fim de manter-se protegido contra as ameaças on-line.
Easter Sunday is one of the most important festivals in the Christian calendar and it is observed anywhere between March 22 and April 25 each year; this year it falls on March 31. Spam messages related to Easter have begun flowing into the Symantec Probe Network. As expected, most of the spam samples are encouraging users to take advantage of products offers, personalized letters, e-cards, as well as clearance sales of cars and replica watches. Clicking the URL will automatically redirect the user to a website containing some bogus offer.

Spammers are also exploiting the event by sending casino spam email using the name “Easter bonnet”. The Easter bonnet represents the tail-end of a tradition of wearing new clothes at an Easter festival.
The following spam sample provides instructions for ways that users can acquire a “bonus”.
“Three different bonuses can produce some extra winnings.”
“Make your deposit and get free spins.”
“Free welcome package up to $500.”
