New Report Outlines How Ransomware, Malicious Spam, Mobile Malware and Other Threats to Consumers Evolved During the COVID-19 Pandemic

BUCHAREST, Romania and SANTA CLARA, Calif. - April 6, 2021 – Bitdefender, a leading global cybersecurity company protecting hundreds of millions of endpoints and systems worldwide, today released the 2020 Consumer Threat Landscape Report, revealing top cybersecurity threats, frequency of threats and cybercrime trends of 2020.

“Our 2020 findings depict consumers under constant assault from cybercriminals looking to capitalize on fear and societal uncertainty accompanying the global pandemic,” said Bogdan Botezatu, director of threat research and reporting at Bitdefender. “Cybercriminals will stop at nothing to use outlier events and human empathy to line their pockets. As the pandemic continues we are constantly seeing attacks evolve through malware delivery mechanisms, inventive social engineering and new exploits.”

The report is based on the analysis of quarter-on-quarter and year-on-year data derived from Bitdefender’s Global Protective Network (GPN) that performs billions of queries per day on millions of endpoints and uses advanced algorithms to identify various threats and attack patterns.

Key findings from the 2020 Consumer Threat Landscape Report include:

  • Ransomware attacks soar worldwide – Overall, ransomware attacks grew an astounding 485% in 2020 when compared to 2019. Attacks in the first and second quarter of 2020 accounted for 64% of all attacks or 19% higher than the first two quarters of 2019.
  • Proprietary operating systems dangerous for IoT – Devices with proprietary operating systems make up 34% of what consumers own and responsible for 96% of all detected vulnerabilities. Bitdefender saw an incredible 338% increase in Smart TV vulnerabilities when compared to 2019.
  • Android used to spread malware and malicious apps – As consumers flocked to video conferencing and sought information about COVID-19, criminals took advantage by hosting fake Zoom download sites and distributing malware-laden apps to spy on users and steal personal data. Thirty-five percent of all Android malware detected came from the Android.Trojan.Agent family followed by Android.Trojan.Downloader at 10% and Android.Trojan.Banker at 7%.
  • Network-attached storage (NAS) devices led in number of vulnerabilities – The number of vulnerabilities found in NAS devices increased by 198% YoY from 2019 to 2020. While NAS devices may not be amongst the most prevalent devices in homes, they potentially pack the most number of unpatched vulnerabilities.
  • Potentially unwanted applications (PUA) on the rise – While PUA might not be malicious per se, they can impact user experience by slowing down systems, display unexpected ads or even install additional software. Bitdefender saw a 320% increase in reported PUA in 2020 when compared to the previous year however, quarterly distribution patterns remained similar suggesting consistent growth.

The report further breaks down these findings and several others by country including Australia, Denmark, France, Germany, Italy Netherlands, Romania, Spain, Sweden, United States and United Kingdom and key region-specific events such as the 2020 United States presidential election.
