Large-Scale Smishing Campaign Targets Multiple Regions 

Researchers have identified a large-scale Phishing-as-a-Service (PhaaS) smishing campaign, dubbed Smishing Error524, which has been active since the second half of 2025. The campaign impersonates more than 260 brands across sectors including telecommunications, financial services, logistics, and consumer rewards programmes. 

Using SMS phishing messages, deceptive error pages, and a network of more than 4,300 phishing domains, the operation seeks to collect personal and payment card information. Activity has been observed across Latin America, Europe, Asia-Pacific (APAC), North America, the Middle East, and Africa. 

The scale of the infrastructure and use of multiple evasion techniques highlight a mature and well-coordinated phishing operation. 

RECOMMENDATIONS 
  • Filter SMS messagescontainingknown smishing indicators. 
  • Train users torecognisebrand impersonation attempts. 
  • Verify payment requests through official channels.
  • EnableMulti-Factor Authentication (MFA).
  • Monitorfor unusual account activity. 
  • ImplementDomain Name System (DNS)and web filtering controls. 
  • Block access to known phishing infrastructure.
  • Educate users not to enter payment details through SMSlinks.
  • Monitor newly registered lookalike domains. 

 

Recruitment-Themed Campaign Targets Aerospace and Defence Organisations 

Researchers have identified a targeted phishing campaign attributed to the Advanced Persistent Threat (APT) group Nimbus Manticore (UNC1549 / Smoke Sandstorm), targeting aerospace and defence organisations across Europe and the Middle East. 

The campaign used recruiter impersonation, job-related lures, and a spoofed hiring portal to encourage users to download a malicious application disguised as a two-factor authentication tool. The malware leveraged a legitimate Microsoft-signed application to establish persistence and communicate with attacker-controlled infrastructure. 

The activity demonstrates the continued use of social engineering techniques and trusted applications to gain and maintain access within targeted environments. 

RECOMMENDATIONS 
  • Verify recruiter identities through official company channels.
  • Block access to newly registered and suspicious recruitment domains.
  • Raise awareness of recruitment-themed phishing attempts.
  • Restrict execution of applications fromAppData, Temp, and Downloads folders.
  • Monitorfor unusual scheduled tasks and persistence mechanisms. 
  • Investigate suspicious communication with cloud-hosted infrastructure.
  • Deploy application allowlisting to preventunauthorisedexecution. 
  • Monitorfor Dynamic Link Library (DLL) sideloading and application hijacking activity.
