Russian hackers exploited a critical Office bug within days of disclosure
One campaign, two infection paths: ZScaler found that exploitation of CVE-2026-21509 did not lead to a single uniform payload. Instead, the initial RTF-based exploit branched into two distinct infection paths, each serving a different operational purpose. The choice of dropper reportedly determined whether the attackers prioritized near-term intelligence collection or longer-term access to compromised systems.In…

Currently, security teams operate in isolation. AppSec monitors the code, CloudSec monitors the cloud, NetworkSec monitors the perimeter. A polyglot attack is designed to seamlessly break through these silos.This happens as follows: A…

APT28 Leverages CVE-2026-21509 in Operation Neusploit
IntroductionIn January 2026, Zscaler ThreatLabz identified a new campaign in-the-wild, tracked as Operation Neusploit, targeting countries in the Central and Eastern European region. In this campaign, the threat actor leveraged specially crafted Microsoft RTF files to exploit CVE-2026-21509 and deliver malicious backdoors in a multi-stage infection chain. Due to significant overlaps in tools, techniques, and procedures (TTPs)…

Attackers Hijack GitHub Desktop Repo to Spread Malware via Official Installer
Threat actors have successfully exploited a design flaw in GitHub’s fork architecture to distribute malware disguised as the legitimate GitHub Desktop installer. The attack chain begins with a deceptively simple but effective technique. Attackers create throwaway GitHub accounts and fork the official GitHub Desktop repository. They then modify the download link in the README file…

Attackers published packages with names just close enough to popular libraries, such as “lodsash,” “expres,” “reacts,” and waited for automation or human error to do the rest. The impact was usually limited, and remediation straightforward.That model began to break in 2025.Instead…

Securing MCP Servers at Scale: How to Govern AI Agents with an Enterprise Identity Fabric
Here’s a scenario you’ve probably seen: A developer downloads a Model Context Protocol (MCP) server from GitHub, runs it locally, connects it to their chat client or agent workflow, authorizes with a Personal Access Token (PAT) that grants excessive permissions, and starts using it. It works great. Then another developer does the same thing. And……
