Tracked as CVE-2024-25153, the shortcoming carries a CVSS score of 9.8 out of a maximum of 10. "A directory traversal within the 'ftpservlet' of the FileCatalyst Workflow Web Portal allows files to be uploaded outside of the intended 'uploadtemp' directory with a specially crafted POST request," the company  said  in an advisory last week.

Google is warning of multiple threat actors sharing a public proof-of-concept (PoC) exploit that leverages its Calendar service to host command-and-control (C2) infrastructure. The tool, called Google Calendar RAT (GCR) , employs Google Calendar Events for C2 using a Gmail account. It was first published to GitHub in June 2023. "The script creates a 'Covert Channel' by exploiting the event descriptions in Google Calendar," according to its developer and researcher Valerio Alessandroni, who goes by the online alias MrSaighnal. "The target will connect directly to Google." The tech giant, in its eighth Threat Horizons Report [PDF], said it has not observed the use of the tool in the wild, but noted its Mandiant threat intelligence unit has detected several threat actors sharing the PoC on underground forums. "GCR, running on a compromised machine, periodically polls the Calendar event description for new commands, executes those commands on the t...

Cybersecurity isn't just another checkbox on your business agenda. It's a fundamental pillar of survival. As organizations increasingly migrate their operations to the cloud, understanding how to protect your digital assets becomes crucial. The shared responsibility model , exemplified through Microsoft 365's approach, offers a framework for comprehending and implementing effective cybersecurity measures.  The Essence of Shared Responsibility  Think of cloud security like a well-maintained building: the property manager handles structural integrity and common areas, while tenants secure their individual units. Similarly, the shared responsibility model creates a clear division of security duties between cloud providers and their users. This partnership approach ensures comprehensive protection through clearly defined roles and responsibilities.  What Your Cloud Provider Handles  Microsoft maintains comprehensive responsibility for securing the foundational eleme...
