"A clean, minimalist vector illustration of Advanced Persistent Threats (APTs). The main visual features a faceless, hooded figure symbolizing a hacker, drawn in simple, angular lines with muted, dark tones. Surrounding the figure is a digital grid with sleek, geometric shapes representing network infrastructure, including servers, computers, and data centers. Red and dark blue vector arrows, lines, and shapes flow through the network, symbolizing continuous infiltration. Iconic symbols like broken locks, phishing hooks, and virus warnings are subtly incorporated. The background uses muted tones with high contrast to emphasize the hacker and network activity in sharp, crisp vector lines."
