In the realm of cybersecurity, the name Fancy Bear sends shivers down the spine of even the most seasoned professionals. This well-known Russian advanced persistent threat (APT) group, linked to the Russian General Staff Main Intelligence Directorate, has once again made headlines with its latest exploit - the Windows Print Spooler bug.
Microsoft Threat Intelligence recently shed light on Fancy Bear's utilization of a custom tool named GooseEgg to leverage the CVE-2022-38028 vulnerability in the Windows Print Spooler service. This exploit, in essence, allows the group to elevate privileges and pilfer credentials, laying the groundwork for a myriad of intelligence-gathering assaults across the globe.

What sets this particular attack apart is not just Fancy Bear's targeting of the service, a tactic not uncommon in its playbook. Rather, it's the innovative employment of GooseEgg to escalate privileges, signifying a significant evolution in the group's modus operandi. This tool, deployed with precision through batch scripts and scheduled tasks, operates with a level of sophistication that is both impressive and concerning.
