Egypt Billboard Hack Exposes 1,926 Screens, Group Says

What happened on the 26 July Corridor

On Thursday, Oct. 29, sexually explicit footage appeared on a large electronic billboard overlooking the 26 July Corridor in Giza, one of the busiest highways connecting Cairo to its western suburbs.

Videos of the screen spread quickly on social media. Egyptian authorities suspended advertising displays along the road and opened an investigation. The billboard is operated by Arabian United, an Egyptian-Saudi advertising venture set up in 2022 by United Media Services (UMS) — the media arm of Egypt's General Intelligence Service — and Saudi-listed Arabian Contracting Services Co.

That ownership mix turned a crude stunt into a bigger story. UMS controls more than 40 companies across television, newspapers, digital media, entertainment and advertising. Arabian Contracting Services holds a 49.99% stake in Arabian United but exercises effective control through 57% of board representation, according to its March 2026 financial statements.

In a Thursday evening statement, Egypt's Interior Ministry attributed the incident to the hacking of an unnamed international advertising company's website and said the same footage appeared on screens in several countries at once. The ministry did not name the company, the countries or any suspects, and it did not explain how a website breach would translate into control over roadside displays.

The hackers' version: a software flaw, not a targeted hit

A person speaking for the group told The Cairo Report that members exploited a vulnerability in the software that transmits content to LED displays, rather than going after the Egyptian billboard individually.

"It was a genuine vulnerability in the software responsible for transmitting content to LED displays," the representative said. "After exploiting it, we gained access to display systems in several countries, not just Egypt, but also Malaysia, Brazil, China, and others." The group operates a Telegram channel called Leakers$, and its address was visible on the pornographic material shown on the Egyptian billboard — which is how The Cairo Report traced and contacted its administrators.

The group said it found targets through automated, random scanning rather than picking specific companies or countries. It named several participants using the pseudonyms Never, 19ylegal, CH and Nivex, and said they identified thousands of exposed systems in roughly two hours. In its public statement, Leakers$ said the goal was to expose security failures, not to demand payment or run a ransomware attack.

"Companies charge millions to build infrastructure across multiple countries and leave LED screens and billboard networks wide open on the internet without basic protection," the statement said. The representative also pushed back on the idea that taking over the screens required advanced skills: "It wasn't nearly as complex an operation as many might imagine."

The unanswered question: bug or just bad configuration?

The group's account broadly matches the ministry's description of an international incident, but it stops short of proving the technical method.

When asked whether the operation relied on an unknown software vulnerability or simply on poorly protected equipment exposed to the public internet, the representative described a software flaw but did not provide enough evidence to establish exactly how the access was gained. That distinction matters: a genuine zero-day in display-management software would put every operator using that product at risk, while open, unauthenticated interfaces are a configuration failure that individual network owners can fix.

Either way, the pattern is familiar. Exposed management panels for connected devices — from building systems to cameras — keep turning up as easy entry points. TechCortex has reported on similar weaknesses in corporate CCTV software, where poorly secured systems became a route into enterprise networks. Digital billboards are the same class of device: internet-connected, often managed remotely, and rarely treated as critical infrastructure until something embarrassing appears on them.

Why billboard networks are an easy target

The numbers explain the scale of the exposure better than any statement.

Arabian Contracting Services' 2025 annual report says its Egyptian subsidiary operates a network of 1,926 advertising billboards, including 239 digital installations, across Cairo, Giza, Alexandria and the North Coast. The company says it supervises, manages and operates every stage of the advertising process in Egypt, from installing screens to securing clients and displaying their content.

That end-to-end role is exactly what the Interior Ministry's account left vague. By pointing to an unidentified "international service provider," the ministry did not clarify who was responsible for the software layer that the hackers say they exploited. For the operators, the lesson is less about Egypt's politics than about basic hygiene: change default credentials, keep display-management interfaces off the open internet, and segment screen networks from everything else.

What it means for you

If you run or buy advertising on digital signage in the US, UK or EU, the incident is a reminder to ask your screen operator how their content-management system is secured and whether it is reachable from the public internet. The group's claim of finding thousands of exposed systems through random scanning suggests the problem is not limited to one country or one vendor.

There is no product recall or consumer fix here. The practical step for businesses is to treat billboard and display networks like any other internet-facing system: audit access, patch the management software, and require operators to explain their security posture in contracts.

The Giza billboard incident is a small embarrassment with a large blast radius. It shows that the screens cities rely on for advertising are ordinary internet-connected computers, often run by contractors with unclear responsibility for security. Until operators treat them that way, the next hijacked billboard is a matter of when, not if.
