Alarum Technologies Provides Update RegardingRecent Law Enforcement Action

Tel Aviv, Israel, July 03, 2026 (GLOBE NEWSWIRE) -- Alarum Technologies Ltd. (Nasdaq: ALAR, TASE: ALAR) (“Alarum” or the “Company”) today provided a further update to its announcement issued on July 2, 2026 regarding recent reports concerning its proxy network operations.

As previously disclosed, on July 2, 2026, the Company and its subsidiary, NetNut Ltd. (“NetNut”), became aware that certain domains associated with NetNut had been seized by the U.S. Federal Bureau of Investigations (“FBI”).

Since that announcement, the Company has continued to analyze the incident and additional domains associated with NetNut have also been seized.

As a result of these developments, the Company is currently experiencing disruptions to a portion of its services. If these disruptions continue for an extended period, they are likely to have a material adverse effect on the Company’s operations, financial results and its ability to provide certain services to its customers.

The Company is devoting substantial resources to investigating the circumstances surrounding these events and is working intensively to obtain additional information regarding the nature and scope of the incident. As of the date and time of this press release, neither the Company nor NetNut has been formally contacted by the FBI or any other governmental or regulatory authority in connection with these matters.

The Company itself is continuing to investigate whether its network or services have been used for malicious, fraudulent or unlawful purposes by third parties. Alarum takes this matter seriously and will fully cooperate with law enforcement to ensure any misuse of its infrastructure is thoroughly investigated and those responsible are held to account.
