Nationwide Cellular Outage Sparks Cyberattack Investigation by Federal Agencies

A widespread cellular outage affecting AT&T, Verizon, T-Mobile, and several other providers has prompted urgent investigations by federal agencies, including the Federal Bureau of Investigation (FBI) and the Department of Homeland Security (DHS).

The outage, leaving thousands of Americans without cellular service, occurred on Thursday and has raised concerns about a potential cyberattack.

Federal Agencies Investigate Possible Cyberattack:

Federal agencies, including the FBI and DHS, are actively investigating the cause of the massive cellular outage that disrupted services for major carriers across the nation.

While specific details have not been disclosed, security experts, such as Lee McKnight from Syracuse University, suggest that the outage bears characteristics of a Distributed Denial of Service (DDOS) attack on core internet infrastructure.

DDOS attacks aim to overwhelm websites or online services by inundating them with a high volume of simultaneous requests, causing server overload and shutdown.

The involvement of federal agencies in the investigation underscores the severity of the situation, reflecting the potential threat posed by cyberattacks to critical communication infrastructure.

Potential Cybersecurity Threats:

McKnight, an expert in national security and counterterrorism, draws parallels between the current outage and previous instances, such as the 2016 Mirai botnet attack that targeted prominent websites like Netflix and Twitter.

He emphasizes the increasing popularity of DDOS attacks among cybercriminals and notes that identifying the perpetrators might be challenging due to the availability of DDOS stressers and booters on the Dark Web.

The mention of cybersecurity threats highlights the evolving landscape of cyberattacks and the need for robust measures to safeguard critical infrastructure.

Speculations on Cloud Misconfiguration:

McKnight speculates on the possibility of a cloud misconfiguration, suggesting that human error might be a contributing factor to the outage.

Cloud misconfigurations involve errors in security settings, leaving systems vulnerable to infiltration.

The professor considers major cloud service providers, like AWS or Azure, experiencing an outage as a potential cause but leans towards the first suspicion being human error or cloud misconfiguration.

The exploration of cloud misconfiguration as a potential cause adds complexity to the investigation, hinting at the multifaceted nature of technological vulnerabilities.

Historical Perspectives and Solar Flare Possibility:

It delves into historical incidents, such as AT&T’s data breaches and a cyberattack on Ukraine’s Kyivstar in 2023, offering context on previous instances of disruptions.

Additionally, the mention of AT&T’s past solar flare interference in 1972 provides a historical perspective on disruptions caused by natural events.

By bringing historical events into the narrative, the article provides a broader context for understanding disruptions in communication systems and the various factors that can contribute to such incidents.


The cellular outage, occurring around 4 am ET and affecting numerous iPhone users, has spurred speculation about its origins, ranging from cyberattacks to potential solar flare interference.

As cellular networks begin to restore services, the article leaves readers pondering the million-dollar question: What triggered this massive outage?
