Prolock

Prolock is a ransomware group that emerged in February 2020, operating with primarily financial motivations through targeted attacks against organizations in the United States. The group's origin and potential affiliations remain largely undocumented in public threat intelligence reporting, with limited information available about whether they operate as an independent entity or utilize a ransomware-as-a-service model. Based on available data, Prolock has demonstrated a targeting preference for financial institutions and government facilities, though detailed information about their specific attack methodologies, initial access vectors, and encryption techniques has not been extensively documented by major security research organizations. The group has maintained a relatively low profile compared to other ransomware operations, with only two publicly documented victims, suggesting either limited operational scope or successful operational security that has kept many of their activities from public disclosure. Current intelligence indicates that Prolock's operational status remains unclear, with insufficient public documentation from major threat intelligence sources to definitively assess whether the group remains active, has ceased operations, or potentially rebranded under a different identity.
