Mobile spam
Spam shipments that mimic messages sent from mobile devices are becoming more and more popular. Kaspersky Lab has detected such messages in many languages. In these missions, it imitates the iPad, iPhone, Samsung Galaxy, and other popular models. These messages had a common element, the very small (or non-existent) text, and signatures such as "Sent from my iPhone". Typically, they contain a link that leads to malicious attachments.
Fake notifications from mobile devices applications
Generally, bulk spam messages mimic alerts from various mobile apps such as Whats App and Viber. Users are familiar with syncing their apps across multiple platforms and synchronizing their contacts between apps and the various notifications that come from them. So, many mobile device owners do not spend much time on their emails, thinking they'll get them on their mobile messenger as well. But this is wrong, as mobile apps are not linked to the user's email account, which proves that many of these messages are obviously false.
"False bank alerts are among the most common types of malicious spam or phishing attacks. Recently, we've noticed remarkable changes to the structure of some phishing email. 2014, spammers began to complicate the design of counterfeit messages by adding more linkto the official sources and services of the agencies from which they claimed that false notices had been sent. Obviously, the attackers hope that an email with a few legitimate ones link should be recognized as legitimate by both users and spam filters. At the same time, this email contains a single malicious link that either redirects users to a phishing site or downloads a malicious file, said Maria Vergelis, Kaspersky Lab's Spam Analyst.
