Researchers exposed the Silent Ransom Group \u2018s Fast Flux infrastructure as the FBI warns of ongoing attacks targeting U.S. law firms and businesses.<\/h2>\n

Resecurity uncovered the Silent Ransom Group (SRG)\u2019s Fast Flux network infrastructure and shares available intelligence with the cybersecurity community to disrupt their malicious activities and enable ISP\/DNS providers to counter this threat. <\/p>\n

\u201cResecurity is the first to uncover the SRG\u2019s Fast Flux network infrastructure and is sharing this intelligence with the cybersecurity community to disrupt their malicious activities and enable ISP\/DNS providers to counter this threat.\u201d reads the report published by Resecurity.<\/p>\n
