XWorm, a popular and actively distributed remote access trojan (RAT), has steadily evolved into a versatile tool in the cybercriminal toolkit. Known for its robust feature set, ranging from keylogging and remote desktop access to data exfiltration and command execution, XWorm continues to attract threat actors due to its ease of use, modularity, and frequent updates by its developers.

Software installer packages are a cornerstone of user-friendly software distribution. Tools like Inno Setup, NSIS (Nullsoft Scriptable Install System), and InstallShield help developers bundle their applications into a single, streamlined installer that users can run with just a few clicks. These installers often include everything needed to set up a program, files, configurations, and even system dependencies, making software installation seamless and accessible.

In this article, we’ll analyze how threat actors exploit TLS to hide their operations and how defenders can use exposed certificate metadata to detect them. We will discuss: Let’s get started! (This article is part of our Threat Hunting with Splunk series. We’ve updated it recently to maximize your value.)

Many Splunk Enterprise Security users are benefiting from machine learning (ML) without even realizing it. Splunk Enterprise Security quietly uses ML-driven anomaly detection to spot unusual patterns or outliers in your security data that static rules or thresholds might miss.

We’re excited to share that Splunk Attack Analyzer recently introduced the ability to translate content and achieved SOC 2 Type II certification.

We’re honored to share that Splunk has been named a Leader in The Forrester Wave: Security Analytics Platforms, Q2 2025. Splunk is committed to power the SOC of the Future by providing a unified threat detection, investigation, and response (TDIR) experience — no matter their deployment requirements.

Large Language Models (LLMs) provide strong reasoning and data summarization capabilities, making them valuable proxies for a variety of cybersecurity operations tasks. However, their performance can decline when applied to highly specific or enterprise-contextual tasks, particularly if the models rely solely on public internet data.

At RSAC 2025 Conference we announced new innovations to Splunk Security. Today, we are pleased to announce the general availability of Splunk Enterprise Security 8.1. Splunk becomes the only vendor to bring truly unified threat detection, investigation, and response (TDIR) workflows fueled by automation to both customer managed deployments and FedRAMP Moderate environments.

Key takeaways Most modern software isn’t built from scratch. It’s assembled from dozens, sometimes hundreds, of external components like open-source libraries, third-party APIs, CI/CD tools, build scripts, and deployment pipelines. This entire ecosystem is what we call the software supply chain. Similar to a physical supply chain, if one weak link breaks, the whole system is at risk.
