COVID-19 and cybercrime - Europol Threat Assessment

Cybercrime has become a dangerous reality in the past 12 months. The conditions created by the global pandemic have caused a rapid pace of transformation in the cyber world. With the accelerated digitization came the threat of increased cyber attacks. Earlier this month, Europol published the Internet Organized Crime Threat Assessment (IOCTA) outlining the key cybercrime trends impacted by COVID-19

What are the most important trends?

  • Ransomware as a Service has enabled a wider range of threat actors to attack large organizations by threatening them with multi-level extortion tactics;
  • Mobile malware has made strides as cybercriminals attempt to bypass multi-factor authentication and other security measures;
  • Online shopping has led to increased online fraud, with phishing and social engineering being the main attack vectors;
  • Dark web users are embracing anonymous cryptocurrencies and swap services. In addition, the exploitation of legitimate services, such as VPNs and encrypted chat platforms, continues to increase.

Mobile malware gets a special section in the report, as cybercriminals are increasingly deploying malware through overlay attacks, SMS spam, and 2FA jamming, among others. Ransomware is also frequently mentioned. It is now almost weekly in the news: ransomware. There has been a clear growth in ransomware attacks since the start of the pandemic. Ransomware groups have taken full advantage of the pandemic to carry out sophisticated and targeted attacks. While massively distributed ransomware is on the wane, gangs and their affiliates are conducting well-orchestrated manual attacks – mostly against large corporations.
