Vulnerability Trends Summary

As part of our monthly vulnerability trends, this report shows the monthly top 10 trends on security vulnerabilities and how hackers, malware, and exploit kits are exploiting those vulnerabilities. To demonstrate, we assign vulnerability trends value as a percentage of how each vulnerability is significantly gaining the attention of cybersecurity communities, attackers, together with malware. In either case, companies can benefit from the report to have more cyber threat insights and relatively anticipate attacks wave that might target their public assets in the following months.
