Prompt Injection and the New AI Attack Surface

-
Prompt injection has moved from a research curiosity to an operational security problem. In plain terms, it is the process of embedding hostile instructions within content that an AI system reads, then causing the model to treat that content as guidance rather than data. That failure occurs because large language models process everything as tokens in a single stream. Human beings see a difference between policy, instructions, retrieved text, email content, and tool output. The model sees sequence, probability, and salience. That design reality makes prompt injection one of the central risks in modern AI systems. Current reporting and primary research indicate that prompt injection has already led to real security consequences. Microsoft’s Copilot vulnerability, tracked as CVE-2025-32711, demonstrated that malicious content could trigger unauthorized network disclosure. Research on EchoLeak documented a zero-click prompt-injection chain in a production LLM environment. Unit 42 also rep...

AI Security and You

-
AI security is the discipline of protecting AI-enabled systems, the data they use, and the environments that support them, while also using AI to strengthen cyber defense. In practice, this means two things. First, security teams use AI to improve detection, triage, threat hunting, and response. Second, they secure the AI stack itself, including models, prompts, training data, inference endpoints, APIs, vector databases, orchestration layers, plugins, service accounts, and the cloud infrastructure that carries the whole system. Both sides matter. One strengthens defense. The other keeps the new technology from becoming a fresh path to compromise. For technical teams, the first step is inventory. Identify every AI-enabled application in the environment. Include public chat interfaces, internal copilots, document assistants, coding assistants, agent-based workflows, retrieval-augmented generation systems, embedded AI features in SaaS platforms, and third-party APIs. For each system, dete...

Deepfake-Resistant Verification: Rebuilding Trust After Voice and Video

-
Security teams used to treat a phone call or video meeting as a high-friction trust channel. That assumption breaks under commodity voice cloning and synthetic video. Familiar tone, recognizable face, and “urgent” delivery carry weak evidentiary value. Verification has to shift from perception-based trust to control-based trust. The risk shows up fastest in two workflows: incident coordination and financial authorization. Synthetic impersonation compresses decision time, increases confidence in false requests, and exploits existing escalation habits. When a request arrives through chat, voice, or video, the channel becomes a delivery vehicle, not proof of identity. The only reliable control is a separate, pre-defined verification path that deepfakes fail to satisfy. Deepfake resilience is a process design problem first. Detection helps, yet process changes reduce reliance on fragile human cues. The objective is simple: every high-impact decision requires an authentication and approval ...

Your Smart Home Is Watching You Back — and AI Does the Remembering

-
People buy smart devices for ordinary reasons. Better streaming. Hands-free timers. A doorbell that shows deliveries. Each purchase feels small and isolated. Over time, those devices form a sensor network inside the home. AI turns that network into memory. Smart televisions from Samsung, LG, and Sony operate as data collection platforms as much as displays. Automatic Content Recognition identifies what appears on screen across streaming apps, cable feeds, and HDMI inputs. Viewing habits, app usage, and interaction timing feed analytics systems tied to advertising and recommendation engines. The result feels like personalization while functioning as behavioral logging anchored to a physical location. Voice assistants intensify exposure. Devices from Amazon and Google buffer audio continuously while waiting for activation phrases. Accidental triggers remain documented, along with human review of recordings for training and quality analysis. AI extracts value from short fragments. Speech ...

Web Shells

-
Web shells have emerged as a formidable tool in an attacker's arsenal. These malicious scripts, often masquerading as legitimate web files, grant unauthorized access and control over web servers, facilitating a range of nefarious activities. Understanding the mechanics, capabilities, and detection methods of web shells is crucial for bolstering organizational cybersecurity defenses. What Is a Web Shell? A web shell is a script, typically written in languages like PHP, ASP, or JSP, that enables remote administration of a web server. While web-based administrative tools are common, web shells are illicitly installed by attackers to execute arbitrary commands, upload or download files, and manipulate server configurations without authorization. They effectively provide a backdoor into compromised systems, allowing persistent access for malicious actors. How Do Web Shells Work? Attackers deploy web shells by exploiting vulnerabilities in web applications, such as file upload flaws, SQL...

Knowing USB

-
USB drives remain a staple in our increasingly digital world. They’re small, portable, and efficient—a convenient solution for transferring and storing data on the fly. However, as cybersecurity threats evolve, USB drives have become a growing liability, posing risks that range from malware infections to sophisticated hardware attacks. In 2024, the threats associated with USB drives have expanded significantly, incorporating advanced malware, AI-enhanced social engineering, and hardware-based exploitation tactics. As someone immersed in cybersecurity, I can tell you that overlooking these risks is no longer an option. Here’s what you need to know about the dangers of USB drives and how to protect yourself in today’s threat landscape. 1. Malware Delivery: Now Enhanced by AI USB drives are still a top choice for delivering malware. However, today’s attackers are leveraging AI to create more sophisticated, adaptive malware that can evade traditional defenses. These advanced threats includ...
