A collaborative operation shut down HeartSender, a Pakistan-based cybercrime group, seizing 39 domains linked to phishing and hacking, impacting thousands and causing over $3 million in losses.

Operation Heart Blocker’s Immediate Impact

On January 29, 2025, US and Dutch authorities executed a decisive strike against cybercrime through ‘Operation Heart Blocker,’ successfully seizing 39 domains and their associated servers [1][2]. The operation targeted a sophisticated Pakistan-based network known as Saim Raza, or HeartSender, which had been actively selling malicious cyber tools since 2020 [3]. The group’s activities had resulted in more than $3 million in victim losses in the United States alone [2][3].

Sophisticated Criminal Infrastructure

HeartSender operated through a network of professional criminal web shops, marketing their tools across various platforms, including YouTube [1]. Their arsenal included sophisticated phishing kits, cookie grabbers, and spam campaign tools designed to be undetectable by antispam solutions [2]. The criminal network provided access to compromised infrastructure, including web servers, SMTP servers, and WordPress accounts [1][2]. The Dutch police highlighted the group’s professional operation methods, noting their ability to enable large-scale spam and phishing campaigns [3].

Extensive Data Compromise

The investigation revealed massive datasets containing millions of victim records, with approximately 100,000 Dutch credentials among them [1]. In response, Dutch authorities have established a website where users can verify if their credentials were compromised [2]. The Dutch police are actively advising affected users to immediately change their login credentials and remain vigilant against potential phishing attempts, as compromised email addresses could be used to target victims’ contacts [2].

Law Enforcement Response

The operation represents a significant achievement in international law enforcement cooperation, with the FBI’s Houston office taking a leading role in the investigation [8]. Assistant U.S. Attorney Rodolfo Ramirez and Trial Attorney Gaelin Bernstein are handling the case [8]. The successful disruption of HeartSender’s operations demonstrates the growing effectiveness of international collaboration in combating cybercrime [5].
