In partnership with the NSA and the FBI, cybersecurity authorities worldwide have released today a list of the top 15 vulnerabilities routinely exploited by threat actors during 2021.
"U.S., Australian, Canadian, New Zealand, and UK cybersecurity authorities assess, in 2021, malicious cyber actors aggressively targeted newly disclosed critical software vulnerabilities against broad target sets, including public and private sector organizations worldwide," the advisory reads.
This might be due to malicious actors and security researchers releasing proof of concept exploits within two weeks since the initial disclosure for most of the top exploited bugs throughout 2021.
The list of the top 15 most exploited security flaws is available below, with links to National Vulnerability Database entries and associated malware.
The US, Australian, Canadian, New Zealand, and UK cybersecurity agencies have also identified and revealed 21 additional security vulnerabilities commonly exploited by bad cyber actors during 2021, including ones impacting Accellion File Transfer Appliance, Windows Print Spooler, and Pulse Secure Pulse Connect Secure.
"We urge all organizations to assess their vulnerability management practices and take action to mitigate risk to the known exploited vulnerabilities."
