![]() ![]() When a system is first brought up, the NSE disks are openly available to the system without need for authentication. The disks themselves automatically encrypt data written to them and decrypt it when read and maintain these disk encryption keys (AKA media encryption keys) within themselves. The controls are not yet set to protect a disk that leaves the system. The system may be operated in this unprotected mode indefinitely. The NSE disks simply act like other disks. When the servers are made available and the required SSL/TLS certificates are properly installed, the setup of the connections between the KMIP servers and the cluster is made. Thereafter, authentication keys can be created and the controls in the disks set to protect the data. Then, if the disks are power-cycled, such as would happen if a disk is removed and placed on another system, that system cannot give the required AK (safely on an SSL-protected key server) to unlock access to the data. Modifying authentication keys does not affect the encryption keys. Data that is written to the disks in the period before KMIP server setup and AK changes is still present. Once the controls are set, then all data on the disks is protected, whether it existed before or after the protections were applied. The disks come with a default key, called the Manufacture Secure ID (MSID), that is unique to each disk. It is electronically readable from the disk, so it provides no protection on its own. This might be what the questioner referred to as “the open key.” When Data ONTAP modifies the AK to a new value the MSID can no longer be used to access the disks, if it should leave the system. Storage encryption is at the disk firmware on self-encrypting disks (SEDs). ![]() SEDs run in unprotected or protected mode (encrypted). Protected mode requires key manager authentication after power-on. There is no noticeable performance decrease or boot time increase. Furthermore, all Data ONTAP storage efficiencies (i.e. You can specify up to 4 key servers during or after setup. This first release is available on VMware Cloud on AWS SDDC Version 16.2. The joint solution allows our customers to extend their on-premises telco clouds built with VMware Telco Cloud Platform. Pakistani Threat Actor SideCopy Targeting Indian Government Agencies Using ReverseRAT BackdoorSanitize (for return) changes the encryption key to a new unknown key.SEDs have two additional features in addition to encryption If you have production and DR site the key managers are clustered together this is a common setup. VMware Telco Cloud Platform Public Cloud is a cloud-smart solution, tightly integrated with VMware Cloud. Keep AV signatures, operating systems, and third-party applications up to date on all systems, mobile devices, and servers. Security administrators should apply the Principle of Least Privilege to all systems and services. System administrators should regularly take backups of the applications, databases, and all critical data. Users should not download, accept, or execute files and do not visit websites or follow links provided by unknown or untrusted sources. Users should not download suspicious applications and attachments received over the internet and be alert to social engineering and phishing attacks. Organizations are recommended to have a behavioral detection solution in place to successfully detect the presence of malware payloads. Security administrators are recommended to make sure that all applications, databases, servers, and network devices are periodically hardened and adequately configured. Security administrators should block the IoCs on all applicable security solutions post-validation. ![]() During recent efforts, however, SideCopy's primary target was Indian government employees who were employing 'Kavach' (meaning "armour" in Hindi) as a two-factor authentication method. It also waits for command execution before doing activities such as screenshot capture, file download and execution, and file upload to the C2 server.įurthermore, in 2021, the SideCopy gang was found delivering ReverseRAT in a series of attacks in India and Afghanistan, where the victims were linked with the government and power utility verticals. ReverseRAT enumerates the compromised device, collects data such as computer name, internal IP, external IP, physical memory, operating system, CPU, and camera, encrypts it all with RC4, and delivers it to a C2 (command-and-control) server. ![]() Once victims open the file, macros are activated, and the malicious code that deploys the ReverseRAT on the victims' machine is executed. The campaign starts by sending a phishing email with an attached macro-enabled Word document called "Cyber Advisory 2023.docm," masquerading as an advisory from India's Ministry of Communications on "Android Risks and Preventions." Also, the contents of the warning have been copied from a study on best cybersecurity procedures published by the department in July 2020. SideCopy is a threat actor of Pakistani origin that shares similarities with the Transparent Tribe. Based on a study provided by cybersecurity firm ThreatMon, a threat actor known as 'SideCopy' is employing an updated version of a backdoor known as 'ReverseRAT' to spear-phish Indian government agencies. ![]()
