The top issues of spam messages for 2016: sport and terrorism

Phishers, as expected, could not pass up the opportunity presented by the most talked about event of the year – the Olympic Games in Brazil. Fraudulent spam also exploited other major sporting events, such as the European Football Championship, as well as the upcoming 2018 and XNUMX FIFA World Cups. . Οι spammers έστειλαν ψεύτικες ειδοποιήσεις για νίκη σε λοταρίες σχετικές με αυτά τα γεγονότα. Η λαχειοφόρος αγορά υποτίθεται ότι είχε διοργανωθεί από επίσημο οργανισμό και η διεύθυνση του παραλήπτη είχε επιλεγεί τυχαία ανάμεσα από εκατομμύρια άλλες διευθύνσεις. Αυτό το θέμα χρησιμοποιήθηκε επίσης σε κακόβουλα spam. Σε αυτήν την περίπτωση, τα email περιελάμβαναν ένα συνημμένο αρχείο ZIP με ένα Javascript downloader και ανιχνεύονται από την Kaspersky Lab ως Trojan-Downloader.Script.Generic. Αυτό το , in turn, "downloads" other malware onto victims' computers.

Το θέμα της τρομοκρατίας, η οποία έχει παραμείνει ένα σημαντικό παγκόσμιο πρόβλημα τα τελευταία χρόνια, ειδικά γύρω από την τεταμένη κατάσταση στη Συρία, αξιοποιήθηκε επίσης σε αποστολές spam. Τα πολυάριθμα λεγόμενα “γράμματα από τη Νιγηρία”, αξιοποιώντας το πρόβλημα της τρομοκρατίας και των προσφύγων, στάλθηκαν στους χρήστες για and government organization employees and individuals. The details of the stories may vary, but the senders' intentions were the same: to grab the recipient's attention with promises of large sums of money and force them to engage in a conversation.

Chinese businessmen on the rise

Spam ads became very popular with small and medium-sized businesses in China, 2016. The text of a standard spam message generally began with an impersonal greeting to the recipient, followed by the name and surname of the factory manager. Often, the email outlined the company's benefits, achievements, and the types of certification it had.

Chinese businesses have not started using new, more targeted, convenient and less intrusive advertising such as social networking sites. Kaspersky Lab researchers believe this may be due to the fact that social networks in China are mostly internal, since "global giants" such as Facebook are not allowed. As a result, Chinese entrepreneurs have far fewer legal means to enter the international market, even though the state has passed its own anti-spam law, which is the strictest in the world.

The "ransom" is the king

In 2016, a huge number of malicious spam was recorded. The absolute leaders of spam were the Trojan downloaders who "download" ransomware to the victim's computer. The most popular were group junk messages sent to "infect" users' computers with the Locky encryptor. However, other ransomware such as Petya, Cryakl and Shade were also prevalent.ransomware

Quantity of malicious spam Email the 2016

The number of malicious programs started to increase in December 2015 and continued to increase in waves throughout the following year. The sharp declines were mainly caused by the fact that digital criminals have temporarily disabled the Necurs botnet, which is responsible for Locky's greater spread.

 "2016, we saw a series of changes in the flows spam, with an increase in the number of malicious bulk shipments they contain ransomware be the most important. Such extensive use of programs ransomware may be due to the existence of this type of malware on the black market. Currently, digital criminals can not just rent one botnet to send spam, but also to use the service known as Ransomware-as-a-service. Αυτό σημαίνει ότι ο εισβολέας μπορεί να μην είναι ένας χάκερ με την παραδοσιακή έννοια, και μπορεί να μην γνωρίζει καν πώς να χρησιμοποιεί . Το 2017, ο όγκος των κακόβουλων spam is unlikely to decrease, said Darya Gudkova, Spam Analyst Expert of Kaspersky Lab.
