Alarum Technologies slumps following FBI probe
Alarum Technologies (Nasdaq: ALAR; TASE: ALAR) shares fell over 70% after the company said some domains tied to its NetNut subsidiary were seized in an FBI investigation. Alarum reported service disruptions and warned of a potential material adverse effect. Google said it disabled accounts linked to alleged malware and degraded NetNut’s proxy network.
How this was made

The 30-second read
Why it matters
The newest disclosed fact is that domains associated with NetNut were seized in an FBI investigation, leading to service disruptions and a company warning of potential material adverse effects if disruptions persist.
Market read
A law-enforcement action directly tied to ALAR’s infrastructure is causing immediate operational disruption and raising enforcement/customer-risk concerns.
What to watch
The company states it has not been formally contacted by the FBI; the ultimate scope (criminal vs. civil, breadth of seized infrastructure, duration of outages) is not yet defined.
Background
Alarum (formerly Safe-T) shifted toward data-collection via its NetNut proxy network, which routes traffic through consumer IPs to mask browsing origin; the article frames this as both legitimate testing and potential misuse.
Ticker impact
Alarum shares plunged after reporting FBI seizure of domains tied to NetNut, suspending data traffic and warning of material adverse effects.
Further downside risk and elevated volatility until service restoration and enforcement scope are clarified.
The article cites a concrete operational disruption (temporary suspension of data traffic) plus a company warning that prolonged disruptions could materially affect operations and financial results.
Market effects
Heightens scrutiny of proxy networks and web data-collection infrastructure; could pressure peers’ compliance posture and customer willingness.
Likely spillover to Israeli TASE-listed cybersecurity/data infrastructure names via heightened regulatory risk sentiment.
US law-enforcement action and Google’s account/service disablement may influence global enforcement and vendor risk assessments.
Counterpoint
If disruptions are limited to seized domains and services can be restored quickly, the market may over-discount worst-case enforcement outcomes.
