U.S. prosecutors in Chicago charged Turkish national Izzet Mert Ozek with directing a distributed denial-of-service attack against a Chicago-based multinational hospitality company, alleging he used the WireX botnet to overwhelm the company’s website and disrupt hotel bookings. The indictment says the August 2017 attack targeted a luxury hotel and resort operator whose web servers were hosted in northern Illinois, and authorities said Ozek is believed to be in Turkey, where an arrest warrant is expected.
WireX was previously dismantled through a joint effort by technology and security firms after researchers linked the botnet to roughly 300 malicious Android apps distributed through Google Play. The malware infected at least 70,000 devices—and telemetry suggested as many as 130,000 to 160,000 unique IP addresses participated in attacks across more than 100 countries—while using headless browser activity and SSL-encrypted traffic to make malicious requests resemble legitimate mobile web traffic, complicating mitigation efforts.

Federal prosecutors in Chicago announced an indictment charging Turkish national Izzet Mert Ozek with directing a WireX-based DDoS attack against a multinational hospitality company. The charge alleges he intentionally caused damage to a protected computer and that a warrant for his arrest would be issued.
On August 17, 2017, multiple CDNs and content providers were hit by significant application-layer DDoS attacks attributed to the WireX Android botnet. Researchers said the attacks involved at least 70,000 concurrent IP addresses from more than 100 countries.
Researchers first saw a small number of compromised Android devices conducting relatively small DDoS attacks, marking the initial emergence of the WireX botnet. This was the first explicit observation of the campaign in the source material.
During August 2017, WireX was used to disrupt several large hospitality-sector websites. A later U.S. indictment alleged one of these attacks targeted a Chicago-based multinational hospitality company and interfered with hotel bookings.
In less than two weeks after first surfacing, WireX grew from a small cluster of infected devices into a botnet of tens of thousands of compromised Android systems. Researchers later estimated at least 70,000 infected devices, with some telemetry showing 130,000 to 160,000 unique IPs in attacks.
Technology and security companies jointly announced that they had dismantled the WireX Android DDoS botnet. The public disclosure tied the botnet to roughly 300 malicious Google Play apps and described attacks originating from devices in more than 100 countries.
Google said it identified about 300 Android apps associated with WireX, blocked them from Google Play, and began removing them from affected devices. The apps appeared benign while secretly installing malware that connected phones to command-and-control servers.
