There is a man sitting at a table with a laptop computer

Create a dark background using shades of gray or dark blue to evoke mystery and alertness; position the silhouette of a person from the side, slightly tilted, with their face turned toward a laptop, in black or dark gray to stand out against the background; place the open laptop in front of the person, with the screen visible in profile, and add a Wi-Fi icon on the screen; over the screen or near the silhouette, add a Wi-Fi icon in white or light blue to contrast with the dark background; next to the Wi-Fi icon, insert a small broken padlock in red or orange to suggest an insecure connection; add a slight glow around the silhouette or the Wi-Fi icon to make them stand out more; insert a small yellow alert triangle with an exclamation point in a corner of the thumbnail to increase the sense of urgency; adjust the contrast and clarity of all elements to ensure the message is clear and attractive, even in a reduced size.
