Using rpcclient from the Samba Suite to Assess and Secure Active Directory Environments

The command-line tool rpcclient, part of the Samba suite, enables direct MS-RPC access to Windows systems from Linux. It supports enumeration of domain accounts, shares, and privileges, as well as write operations against SAM and LSA. Originally developed to test Samba's MS-RPC implementation, the utility has become a standard component in the toolkits of pentesters, auditors, and administrators working with Active Directory. From a Linux environment, rpcclient provides access to multiple named pipes including SAM, LSA, NETLOGON, SRVSVC, and SPOOLSS without requiring graphical interfaces. The article demonstrates practical usage through concrete commands against domain controllers and organizes them by common administrative and security-assessment scenarios. This approach allows security teams to perform detailed inventory and privilege analysis directly from the command line.

Netscout 1H 2026 Report: High-Power DDoS Attacks Surge 1,286 Percent as Carpet-Bombing and Residential Proxies Rise

Netscout recorded more than 9.1 million DDoS attacks worldwide in the first half of 2026 across 209 countries and territories. High-performance attacks exceeding 1 Tbps or 1 Gpps increased by 1,286 percent compared with the same period in 2025. Direct-Path attacks accounted for 64 percent of observed incidents, while Carpet-Bombing attacks rose from 3.97 percent to 4.54 percent. The share of attacks lasting one minute or less doubled since the second half of 2023, reaching 3.1 percent. Residential-proxy networks increasingly mask malicious traffic as legitimate user requests, rendering single-IP analysis insufficient. Netscout also documented the first IPv6 attack above 1 Tbps and a more than 300 percent year-over-year increase in active IPv6 mitigation. Organizations are advised to protect networks, applications, and IPv6 infrastructure comprehensively, supplementing on-premises capacity with cloud-based defenses when needed.
