Updating zones files named via commandline
A list of registry changes can be found here: https://support.microsoft.com/en-us/help/4072698/windows-server-guidance-to-protect-against-the-speculative-execution Antivirus Typical antivirus programs are built on a signature management system, and may not be able to detect the vulnerabilities.
NCCIC recommends checking with your antivirus vendor to confirm compatibility with Meltdown and Spectre patches.
The greatest concentrations of dynamic IPs addresses are identified below by approximate percentage: As a backdoor Trojan, Volgmer has several capabilities including: gathering system information, updating service registry keys, downloading and uploading files, executing commands, terminating processes, and listing directories.
In one of the samples received for analysis, the US-CERT Code Analysis Team observed botnet controller functionality.
This alert includes IOCs related to HIDDEN COBRA, IP addresses linked to systems infected with Volgmer malware, malware descriptions, and associated signatures.
DHS and FBI are distributing these IP addresses to enable network defense and reduce exposure to North Korean government malicious cyber activity.In the case of Spectre, the vulnerability exists in CPU architecture rather than in software, and is not easily patched; however, this vulnerability is more difficult to exploit.After patching, performance impacts may vary, depending on use cases.CPU hardware implementations are vulnerable to side-channel attacks, referred to as Meltdown and Spectre.
Meltdown is a bug that "melts" the security boundaries normally enforced by the hardware, affecting desktops, laptops, and cloud computers.
NCCIC recommends administrators ensure that performance is monitored for critical applications and services, and work with their vendor(s) and service provider(s) to mitigate the effect, if possible.
