Vulnerable and unpatched plugins pose a serious security problem, creating a gold mine for cybercriminals. In the past 24 hours, security experts have found threats affecting the Ultimate GDPR & CCPA Compliance Toolkit and Thrive Themes plugins for WordPress. While the former is being targeted by a Golang-based botnet that could let attackers redirect traffic to a malicious website, the latter is being actively exploited in the wild to upload arbitrary files on vulnerable WordPress sites.

Researchers also got hold of over 100 indicators for the infrastructure behind a new variant of Agent Tesla that is capable of stealing information via HTTP, SMTP, and FTP. The first attack campaign involving this variant was observed in November 2020.
