Security expert Kaspersky provided data on phishing attacks for the second quarter of 2019 and placed Portugal in the TOP 10 of the most attacked countries, namely fifth place worldwide with 17.47%. The most affected country was Greece with 26.20%, evaluating antiphishing activations in the same period, followed by Venezuela with 25.67%, Brazil with 20.86% and Australia with 17.73%. Spain comes in sixth place with 15.85%.
Kaspersky says attackers are more sophisticated and use effective and convincing phishing techniques using cloud storage systems such as Google Drive for their campaigns. It is also noted that attackers try to weaken the online reputation of companies if they do not give in to blackmail.
Attackers use cloud storage systems and services to make phishing emails more credible. By including an email in a link to a legitimate domain, such as Google Drive, the message gives victims more confidence while avoiding spam detection filters. One example is the phishing links contained within fake event calls using Google Calendar, and if they are photographs, Google Photos.
In the analysis of this second quarter of the year, the expert detected travel-related messages, for example, with letters on behalf of well-known vacation rental web pages, with offers of very competitively priced villas. Many of these proposals contained limited timeframes to put pressure on victims to act spontaneously.
Kaspersky researcher Maria Vergelis stresses the effectiveness of these spam and phishing attacks when they match key dates, which can be received with less suspicion. "Often the victim is unaware that she has been cyber-attacked or exposed her personal data until it is too late," said the expert.
The expert also provided some data from its report for the second quarter of 2019. The number of phishing attacks increased 21% compared to the same period last year, with a total of 129.93 million. There was also a 58% increase in spam volume in email traffic. China is the main spammer, with 23.72%, followed by the United States with 13.89% and Russia with 4.83%. Already the main spam recipient country is Germany with 10.05%, with Russia second with 6.16% and Vietnam with 5.98%.
In August, Google revealed that it blocks 100 million emails daily, leaving even some tips for dealing with the danger of phishing.
