From OLAP to OLTP: How Copel Simplified Reverse ETL Using BigQuery’s Native Export to AlloyDB
Bridging the gap between analytical systems (OLAP) and transactional databases (OLTP) is notoriously complex. Synchronizing
Nightmare Eclipse, the pseudonym of a researcher with an ongoing, very public beef with Microsoft, has dropped yet another Windows zero-day.
On Tuesday, Nightmare Eclipse disclosed SignDrop, a vulnerability that gives local users full System rights on some versions of Windows. The vulnerability resides in the Common Log File System, which Microsoft describes as a “general-purpose logging service used by software clients running in user-mode or kernel-mode.” By forcing a privileged process such as Windows Defender to open a crafted CLFS container, an attacker with ordinary user rights can abuse the privileged file creation to elevate privileges to System.
The attack exploits the interaction of CLFS, Windows Defender, and Windows file permissions. The exploit uses Windows Defender to open a log file created by a standard user by calling ServerMpUpdateEngineSignature, a legitimate Defender function for processing antivirus signature updates.
