Os phishing de e-mails, mensagens que tentam convencer o usuário a digitar dados pessoais, tiveram um aumento drástico em Julho. De acordo com o último relatório da Fortinet, no último mês observou-se um grande aumento de e-mails falsos tentando enganar usuários, com destaque para falsos e-mails do site de leilões eBay.
O pesquisador Patrick Nolan afirmou que os falsos e-mails do eBay são extremamente semelhantes aos e-mails verdadeiros. Os vírus, por sua vez, tiveram uma queda de disseminação, mas as variantes do worm MyTob ainda merecem destaque. A queda é justificada pelo avanço tecnológico dos softwares antivírus que, verificam e bloqueam arquivos com extensões perigosas, como .EXE, .SCR e .PIF.
Email phishing, most notably targeting eBay users, continued to rise dramatically in July, IT security watchers warned today. According to the latest monthly threat report from Fortinet, last month saw a hike in HTML-based phishing emails purporting to come from Ebay. These phishing emails are sent to target email addresses to fool users to sign onto a web page using their eBay logins. The web pages are not affiliated with eBay and may track login information in order to steal data.
Fortinet researcher Patrick Nolan said: "On a scale of 1 to 10 on creativity, the HTML/Ebay-phish phishing scam earns high marks on fooling users." MyTob variants were observed on an almost daily basis but spreading of MyTob appears to be reduced, the study found. This containment was attributed to use of improved heuristics that could detect the virus quickly coupled with increased blocking of dangerous file extension types such as .EXE, .SCR and .PIF.
