Her report Kaspersky Lab for its landscape spam and phishing threats in the second quarter of 2015 reveals that messages based on real events dominated at this time.
In particular, "Nigerian scam" financial scams saw spam that exploited issues such as the earthquake in Nepal, the Nigerian presidential election, and the Rio de Janeiro Olympics. In this way, the attackers were trying to retrieve personal data and persuade Internet users to make voluntary donations.
Although the percentage of spam on the total volume of email decreased by 5,8 percentage points compared to the previous quarter (from 59,2% to 53,4%), the second quarter of 2015 saw a significant increase in the use of global events in spam.
Among other things, there were fake messages asking the recipients to make a donation to help the victims of the earthquake in Nepal. In other malicious bulk mails, scammers tried to lure recipients with the amount of $ 2.000.000, which is supposed to be ready to send to the user as compensation for the newly elected president of Nigeria.
In addition, there have been fraudulent notices for raffles that allegedly gave tickets to the 2016 Olympic Games in Brazil in an attempt to persuade recipients to send their personal data to the scammers to receive their "gift".
Η Tatyana Shcherbakova, Antispam Analyst at Kaspersky Lab said: “During the second quarter of 2015, we noticed that spammers used tragic events to trick users. It's a tactic scammers have used in the past, but with events like the Nepal earthquake, which are covered so much by the Media globally, these messages are likely to evoke the sympathy of recipients. To protect themselves, users should not open emails from unknown senders and remember not to follow links found in emails and not to open attached files. With so many fraudsters trying to make the sender's name and address look more legitimate, this is more important than ever."
