The Kaspersky IT Threat Evolution Q2 2019 report suggested cyber-attacks significantly increased during the period April-June 2019. Security researchers highlighted more than 230,000 Internet users were affected by some attack or the other during the second quarter this year. Researchers also observed a significant increase in the number of new modifications made to ransomware belonging to some new malware families.
Security researchers also detected a 26 per cent decrease in terms of the number of malicious attacks originated from around the world compared to the same period last year. However, researchers observed a 6 per cent growth in terms of the number of malware attempts made to steal money via online access to bank accounts compared to Q2 2018. Kaspersky antivirus found an increase in terms of the number of malicious files detected compared to the same period last year. Last but not least, Kasperksy mobile security saw a significant 57 per cent decrease in terms of the number of malicious packages installed on mobile phones as compared to Q2 2018.
Kaspersky researchers said the second quarter of the year experienced a high number of infection attempts. According to the data provided by the cyber security firm, 232,292 unique users were targeted by such attacks, recording 46 per cent increase than last year. Majority of Internet users attacked Bangladesh (9 per cent), Uzbekistan (6 per cent) and Mozambique (4 per cent). The infamous WannaCry ransomware was most active during the second quarter. Almost 24 per cent of users were affected by WannaCry alone. On the hand, Gandcrab was the second most used ransomware family to attack users with a 13.8 per cent share.
"In this quarter we observed an increase in the number of new ransomware modifications, even though the Gandcrab family closed down in early June. The GandCrab ransomware family has long been one of the most popular cryptors amongst cybercriminals. For more than 18 months it has stayed in the list of the most rampant ransomware families we detect, but even its decline did not lower the statistics, as there are still other numerous widespread Trojans. The GandCrab case is a good illustration of how effective ransomware can be, with its creators stopping their malicious activity after claiming they made a tremendous amount of money by extorting funds from their victims. We expect new actors to replace GandCrab and urge everyone to protect their devices by installing software updates regularly and choosing a reliable security solution," said Fedor Sinitsyn, a security researcher at Kaspersky.
