Cyber Attacks on U.S. House of Representatives Surge to 3 Billion in 2025

Washington, March 18: The U.S. House of Representatives faced a significant rise in cyber threats in 2025. Officials reported that the House’s websites experienced 3 billion attacks, with staff receiving 178 million potentially harmful emails.

During a hearing by the House Appropriations Subcommittee on the fiscal year 2027 budget proposal, senior officials detailed the severity of these threats. They requested additional funding to strengthen cybersecurity and modernize internal systems.

Acting Chief Administrative Officer Anne Dressendorfer Binstead stated that the number of attacks underscores the need for investment in cybersecurity. She informed lawmakers, “During this brief statement, there were nearly 30,000 intrusion attempts.”

She warned that Congress remains a critical target. Binstead noted, “Congress is a target in every sense. It is certainly a prime target for the most sophisticated state-sponsored cyber attackers.”

The Chief Administrative Officer’s office has requested $253 million for fiscal year 2027, an 8.5 percent increase from the previous year. Binstead explained that 80 percent of this increase will be spent on maintaining operations, including personnel, hardware, software, and licenses, while 20 percent will fund new high-priority projects. One major initiative is to expand multi-factor authentication for devices used by members and staff.

Currently, the House utilizes approximately 55,000 desktops, laptops, and mobile devices, many of which are used outside Washington, creating what Binstead described as a “last point of weakness.”

Binstead further stated that the House is already implementing multi-factor authentication on mobile devices and plans to extend it to all computers. Once in place, users will rely on more secure systems such as facial recognition, touch ID, and push notifications.

Another proposal includes creating a secure cloud environment where artificial intelligence tools can be tested using House data without exposing it to external risks.

Binstead emphasized that the House needs customized solutions rather than relying solely on “ready-made products.” She also highlighted the unauthorized use of applications by staff as “shadow IT,” stating, “In my opinion, this is one of the biggest risks. Better awareness and compliance are necessary to mitigate this risk.”

House Sergeant at Arms William McFarland stated that cybersecurity is now a top priority for his office. Addressing the panel, he said, “Cybersecurity is definitely our top priority, and we call for broad participation from members in existing security programs.”

McFarland noted that his office is requesting $147.28 million for fiscal year 2027, a 4.75 percent increase. This funding will support various initiatives, including personal security programs for members, mobile emergency applications, and enhanced cybersecurity measures for lawmakers and their families.

Meanwhile, House Clerk Kevin McCumber highlighted ongoing efforts to modernize legislative operations and improve efficiency. His office has requested $51.79 million, which is 5.71 percent more than the current budget.

McCumber mentioned the implementation of an AI-based speech-to-text system for House proceedings. He stated that it “demonstrates high accuracy and saves approximately $500,000 annually, including improvements such as closed captioning and Spanish language support.”

McCumber concluded by emphasizing the importance of determination in achieving victory, stating, “We are determined to win, and we will achieve our goals.”
