ISLAMABAD, Pakistan — May 29, 2025 — Pakistani authorities have arrested 21 individuals linked to the notorious cybercrime service known as Heartsender, a platform that has been facilitating spam and malware distribution for over a decade. The arrests were made following coordinated raids conducted by the National Cyber Crime Investigation Agency (NCCIA) in Lahore’s Bahria Town and Multan on May 15 and 16, 2025.

What Is Heartsender?

Heartsender, also known as Saim Raza or The Manipulators, operated as an online marketplace offering a range of cybercrime tools, including phishing kits, scam pages, and email extractors. These tools were primarily sold to transnational organized crime groups, enabling them to execute large-scale fraud operations targeting individuals and businesses worldwide. The service was particularly known for its ability to bypass security filters, making it a preferred choice for cybercriminals.

International Crackdown

The recent arrests in Pakistan are part of a broader international effort to dismantle the Heartsender network. In January 2025, U.S. and Dutch authorities coordinated the seizure of 39 domains and associated servers used by the group. This operation, dubbed Operation Heart Blocker, aimed to disrupt the group’s activities and prevent further victimization. The U.S. Department of Justice estimated that the tools sold by Heartsender resulted in over $3 million in financial losses in the United States alone.

Pakistani Authorities’ Statement

The NCCIA, in collaboration with local law enforcement, initiated the operation after receiving intelligence about the group’s activities. The arrested individuals are believed to have been involved in the development, marketing, and distribution of Heartsender’s malicious tools. Authorities have not disclosed the identities of the arrested suspects but have indicated that the investigation is ongoing.

Implications and Future Actions

The dismantling of the Heartsender network marks a significant achievement in Pakistan’s efforts to combat cybercrime. However, experts warn that the proliferation of such services remains a concern. The ease of access to cybercrime tools and the anonymity provided by the internet continue to pose challenges for law enforcement agencies worldwide.

In response to the growing threat, Pakistani authorities have pledged to enhance cybersecurity measures and collaborate with international partners to prevent the emergence of similar networks. The NCCIA has also called on the public to remain vigilant and report any suspicious online activities to help curb the rise of cybercrime in the region.

For more information or to report cybercrime activities, individuals are encouraged to visit the official NCCIA website or contact their local law enforcement agencies.
