Smishing and Vishing

Detect and disrupt smishing and vishing attacks that use SMS and voice calls to impersonate trusted organisations. Protect customers from social engineering scams through rapid identification and coordinated takedown

Detect and Disrupt Smishing and Vishing Campaigns

Smishing and vishing attacks use SMS messages and voice calls to impersonate trusted organisations, pressure victims, and drive immediate action. These scams often reference account issues, missed deliveries, payments, or urgent security alerts, and increasingly form part of broader, multi channel fraud campaigns.

Unlike phishing websites or fake apps, smishing and vishing threats move quickly and rely heavily on social engineering. By the time a campaign is visible, customers are often already being targeted. Rapid takedown and disruption are therefore critical.

unphish supports organisations by focusing on fast, coordinated enforcement to dismantle smishing and vishing campaigns once they are identified.

Smishing Tactics

How smishing and vishing campaigns operate

Smishing and vishing campaigns use SMS messages and voice calls to impersonate trusted organisations and pressure victims into urgent actions. Common tactics used in these attacks include:

High-Volume SMS Campaigns

Smishing attacks distribute large volumes of fraudulent SMS messages impersonating trusted organisations. Messages often create urgency around payments, deliveries, or account alerts to push victims into immediate action.

Impersonation Voice Calls

Vishing campaigns use scripted phone calls where attackers pose as banks, support teams, or service providers. Victims are pressured to reveal sensitive information or approve fraudulent transactions.

Rapid Infrastructure Rotation

Attackers frequently rotate phone numbers, SMS sender IDs, and call scripts to evade blocking. This constant change allows campaigns to continue targeting victims even after initial detection.

Phishing and Fraud Redirection

Smishing and vishing messages often direct victims to phishing websites, fake support lines, or fraudulent payment channels designed to capture credentials, personal data, or financial details.

Why unphish

Why Customers Choose unphish

unphish turns fragmented, reactive threat response into a single, automated workflow. Faster detection, consistent takedowns, full visibility.
unphish Fragmented / Reactive Approach
Threat Visibility Continuous monitoring across domains, hosting, social platforms, and attacker infrastructure. Limited visibility based on complaints or isolated alerts.
Detection Speed Automated detection and risk scoring identify threats early. Threats are discovered late, often after impact.
Infrastructure Insight Deep analysis reveals campaign links, infrastructure reuse, and attacker patterns. Little or no visibility into shared infrastructure or repeat activity.
Enforcement Execution Coordinated workflows enable faster, consistent takedown across platforms. Manual submissions slow down response and create inconsistent outcomes.
Verification & Control Automated validation confirms removal and tracks reappearance. No structured verification or monitoring after takedown.
Operational Visibility Unified dashboards provide clear status, timelines, and reporting. Siloed tools limit visibility and create operational gaps.

Disrupting Smishing and Vishing Campaigns

unphish focuses on dismantling the infrastructure that enables smishing and vishing rather than treating each message or call in isolation.

For each campaign, unphish automatically gathers evidence from referrals and linked infrastructure, including message content, phone numbers, domains, hosting details, and redirection paths. This evidence supports fast and defensible enforcement actions.

By focusing on referral driven response and infrastructure level disruption, unphish enables a practical and effective defence against some of the most persistent scam techniques in use today.
