Financial Data Still Tops Malicious Spam Hit List
For a fourth consecutive year, programmes designed to steal users’ logins, passwords and other confidential data remain top of the list of the most widespread malware distributed by email, according to Kaspersky Lab.
The internet security specialist summarised spammer activity for 2014 as follows:
Kaspersky Lab adds that spam mailings imitating emails sent from mobile devices are becoming very popular. Such emails are being distributed in several languages and mention a variety of devices, including iPad, iPhone, Samsung Galaxy and other models.
These messages shared a common characteristic – very short (or non-existent) text and a signature reading “Sent from my iPhone”. Typically, they contain links to malicious attachments.
Generally spam mass mailings imitate notifications from different mobile applications such as WhatsApp and Viber. Users are familiar with the synchronisation of cross-platform apps and the fact that contact data and notifications are often shared between apps.
As a result many mobile device owners don’t think twice about opening an email saying that something has arrived on their mobile messenger. However, these mobile applications are not connected to the user’s email account, which proves that such emails are obviously fake.
“Fake bank notifications are among the most common types of malicious spam or phishing attacks,” said Maria Vergelis, spam analyst at Kaspersky Lab. “Recently, we have seen noticeable changes in the structure of some phishing emails.
“In 2014, spammers began to complicate the design of fake messages by adding more links to official resources and services of the organisations from which they claim to be sending their bogus notifications. Obviously, the attackers hope that an email with a few legitimate links would be recognised as legitimate by users and spam filters alike. Meanwhile, the email contains a single fraudulent link that either redirects users to a phishing site or downloads a malicious archive.”
Earlier this week, Kaspersky Lab reported that nation-state sponsored cyberespionage attacks are growing in sophistication.
