As 2025 draws to a close, security professionals face a sobering realization: the traditional playbook for web security has become dangerously obsolete. AI-powered attacks, evolving injection techniques, and supply chain compromises affecting hundreds of thousands of websites forced a fundamental rethink of defensive strategies. Here are the five threats that reshaped web security this year, and

### Summary A security issue exists in the `exec_in_pod` tool of the `mcp-server-kubernetes` MCP Server. The tool accepts user-provided commands in both array and string formats. When a string format is provided, it is passed directly to shell interpretation (`sh -c`) without input validation, allowing shell metacharacters to be interpreted. This vulnerability can be exploited through direct command injection or indirect prompt injection attacks, where AI agents may execute commands without explicit user intent. ### Details The MCP Server exposes the `exec_in_pod` tool to execute commands inside Kubernetes pods. The tool supports both array and string command formats. The Kubernetes Exec API (via `@kubernetes/client-node`) accepts commands as an array of strings, which executes commands directly without shell interpretation. However, when a string format is provided, the code automatically wraps it in shell execution (`sh -c`), which interprets shell metacharacters without any input v...

The threat actor known as Water Saci is actively evolving its tactics, switching to a sophisticated, highly layered infection chain that uses HTML Application (HTA) files and PDFs to propagate a worm that deploys a banking trojan via WhatsApp in attacks targeting users in Brazil. The latest wave is characterized by the attackers shifting from PowerShell to a Python-based variant that spreads the

Your antivirus scans files. But what about attacks that never create files? Here's how we catch the threats hiding on your family's computers.

Koi Security exposes ShadyPanda, a group that used trusted Chrome/Edge extensions to infect 4.3 million users over 7 years for deep surveillance and corporate espionage.

New Fooder loader and memory-only tactics suggest MuddyWater has evolved from its usual noisy ops to more stealthy espionage operations.

North Korean hackers escalated the "Contagious Interview" attack, flooding the npm registry with over 200 malicious packages to install OtterCookie malware. This attack targets blockchain and Web3 developers through fake job interviews and coding tests.

Israeli entities spanning academia, engineering, local government, manufacturing, technology, transportation, and utilities sectors have emerged as the target of a new set of attacks undertaken by Iranian nation-state actors that have delivered a previously undocumented backdoor called MuddyViper. The activity has been attributed by ESET to a hacking group known as MuddyWater (aka Mango

A threat actor known as ShadyPanda has been linked to a seven-year-long browser extension campaign that has amassed over 4.3 million installations over time. Five of these extensions started off as legitimate programs before malicious changes were introduced in mid-2024, according to a report from Koi Security, attracting 300,000 installs. These extensions have since been taken down. "These

Hackers aren’t kicking down the door anymore. They just use the same tools we use every day — code packages, cloud accounts, email, chat, phones, and “trusted” partners — and turn them against us. One bad download can leak your keys. One weak vendor can expose many customers at once. One guest invite, one link on a phone, one bug in a common tool, and suddenly your mail, chats, repos, and
