Microsoft and Partners Execute Unprecedented Takedown of Amadey and StealC Cybercrime Tools
In June 2026, Microsoft, in collaboration with international law enforcement agencies and industry partners, executed a court-authorized operation to simultaneously disrupt the Amadey botnet and StealC infostealer. These tools, often used in tandem by cybercriminals, were linked to over 140,000 infected computers globally in early May 2026. The operation targeted more than 200 command-and-control servers, significantly hindering the infrastructure supporting these malware families. This coordinated effort marked a strategic shift in cyber defense, emphasizing the importance of disrupting interconnected cybercrime tools to enhance the effectiveness of takedown operations. The success of this operation underscores the necessity for collaborative approaches in combating sophisticated cyber threats that exploit modular, pay-as-you-go models to escalate attacks rapidly.
