However, the staggering numbers came from the attacks on cloud users. The cyber security company observed nearly 3.1 million external attacks on cloud user accounts. The data comes from the aggregation of cloud usage data from more than 30 million McAfee MVISION cloud users worldwide during Q4 2020. “This data set represents companies in all major industries across the globe, including financial services, healthcare, public sector, education, retail, technology, manufacturing, energy, utilities, legal, real estate, transportation, and business services,” stated the release.

“The world—and enterprises—adjusted amidst pandemic restrictions and sustained remote work challenges, while security threats continued to evolve in complexity and increase in volume,” said Raj Samani, McAfee fellow and chief scientist. “Though a large percentage of employees grew more proficient and productive in working remotely, enterprises endured more opportunistic COVID-19 related campaigns among a new cast of bad-actor schemes. Furthermore, ransomware and malware targeting vulnerabilities in work-related apps and processes were active and remain dangerous threats capable of taking over networks and data, while costing millions in assets and recovery costs.”
