Zimperium has released new research highlighting the evolving landscape of mishing (mobile-targeted phishing) attacks. The data-driven analysis of mobile phishing vectors in 2024 underscores an urgent need for organizations to adopt mobile-specific security strategies to combat these increasingly sophisticated threats, as evidence shows that attackers have moved to a ‘mobile first’ strategy to penetrate corporate networks and sensitive data.
Key findings from Zimperium’s Mobile Phishing Report include:
- Smishing (SMS/text based phishing) remains the most common mobile phishing vector, with 37% of attacks in India, 16% in the US, and 9% in Brazil.
- Mobile-targeted email phishing is increasing with attacks specifically designed to evade desktop security measures, executing only on mobile devices.
- Quishing (QR code phishing) is emerging, with notable activity in Japan (17%), the US (15%), and India (11%).
- 3% of phishing sites use device-specific redirection, showing benign content on desktops while targeting mobile devices with phishing payloads.
- Research shows attackers reusing CIDR blocks to host multiple phishing domains, extending attack reach and persistence.
- Mishing activity peaked in August 2024, with over 1,000 daily attack records.
The strategic implications for enterprise security
As organizations increasingly rely on mobile devices for business operations, including multi-factor authentication and mobile-first applications, mobile phishing poses a severe risk to enterprise security. Attackers are exploiting security gaps in cloud and mobile business applications, expanding the attack surface and increasing exposure to credential theft and data compromise. Traditional anti-phishing measures designed for desktops are proving inadequate, requiring a shift to mobile threat defense solutions on the mobile device.
Mishing is not just an evolution of traditional mobile phishing tactics – it is an entirely new category of attack engineered to exploit the specific capabilities and vulnerabilities of mobile devices, such as cameras. Our research shows that attackers are increasingly leveraging multiple mobile-specific channels – including SMS, email, QR codes, and voice phishing (vishing) – to exploit user behaviors and expand their attack surface.
