Technical Analysis: Multi-Vector Threats Spanning Web Skimming, AI Prompt Injection, and Volumetric DDoS

Redundant Exfiltration: The Rise of ‘Double-Tap’ Skimmers

Recent observations in the e-commerce sector indicate a shift toward redundant JavaScript-based skimming. These ‘Double-Tap’ skimmers deploy secondary payloads that activate only if the primary exfiltration script is detected or blocked by Content Security Policy (CSP) headers. By utilizing multiple domains for data exfiltration and obfuscated WebSockets for transport, threat actors are maintaining persistence on compromised checkout pages longer than traditional Magecart implementations.

LLM Vulnerabilities: PromptSpy and Indirect Injection

The emergence of PromptSpy highlights significant risks in the integration of Large Language Models (LLMs) into enterprise workflows. This framework exploits indirect prompt injection vulnerabilities, allowing attackers to manipulate model outputs through poisoned external data sources. As organizations evaluate their exposure to these external-facing risks, utilizing automated tools like Pocket Pentest for infrastructure scanning provides the necessary visibility into open ports and misconfigured container APIs. Technical controls must move beyond simple input filtering to include semantic firewalls and rigorous output validation.

Scalable Volumetric Attacks: 30Tbps DDoS Benchmarks

Network infrastructure teams are reporting a surge in volumetric Distributed Denial of Service (DDoS) activity, with peak traffic reaching 30Tbps. These attacks leverage a combination of DNS amplification and modernized botnets utilizing the HTTP/2 protocol. The scale of these events suggests a shift in botnet orchestration, moving away from low-bandwidth IoT devices toward high-performance cloud instances and compromised server infrastructure. Mitigation strategies require automated rate limiting at the edge and deep packet inspection (DPI) to identify malformed headers.

Containerized Threats: Docker Malware Persistence

Security researchers have identified new malware strains targeting Docker Hub environments. These campaigns utilize ‘typosquatted’ image names to trick developers into pulling malicious base images. Once deployed, the malware executes container escapes to gain root access to the host OS, facilitating lateral movement within Kubernetes clusters. Hardening container runtimes and implementing strict image signing protocols (such as Sigstore/Cosign) are mandatory to mitigate these supply chain risks.
