U.S. prosecutors have charged three cybersecurity professionals for their alleged role in BlackCat ransomware attacks. The accused, formerly of Sygnia and DigitalMint, allegedly exploited insider access to extort clients, exposing a serious insider threat and need for stronger industry oversight.
The Australian Signals Directorate (ASD) has issued a critical alert regarding the BADCANDY malware, which is actively exploiting a Cisco vulnerability to compromise hundreds of devices across Australia. The non-persistent web shell allows attackers to reinfect unpatched systems repeatedly.

U.S. prosecutors have charged three cybersecurity professionals for their alleged role in BlackCat ransomware attacks. The accused, formerly of Sygnia and DigitalMint, allegedly exploited insider access to extort clients, exposing a serious insider threat and need for stronger industry oversight.
Cyber News Centre’s cyber update for 5th November 2025: In a rare and unsettling breach of industry trust, three American cybersecurity professionals have been charged for their alleged roles in a series of BlackCat ransomware attacks. The accused are believed to have turned their insider knowledge into a weapon against the very organisations they were hired to defend.
The Update: The U.S. Department of Justice has indicted Ryan Clifford Goldberg, 33, a former incident response manager at Sygnia, and Kevin Tyler Martin, 28, a ransomware negotiator at DigitalMint, along with an unnamed co-conspirator also employed at DigitalMint. The trio allegedly acted as affiliates for the BlackCat (also known as ALPHV) ransomware operation.
Court filings claim the group targeted at least five U.S. companies, including a medical device manufacturer, a pharmaceutical firm, a doctor’s office, an engineering company, and a drone manufacturer. Their tactics reportedly involved breaching corporate networks, stealing sensitive data, and deploying BlackCat ransomware to encrypt systems before demanding multimillion-dollar cryptocurrency ransoms. In one case, the group extorted approximately $1.27 million from a Florida-based medical device firm after an initial demand of $10 million. Each faces up to 50 years in prison if convicted.
Why It Matters: This case underscores the growing risk of insider threats within the cybersecurity industry itself. When trusted defenders become attackers, the foundation of corporate and national digital defence is undermined. It raises urgent questions about how firms vet, monitor, and manage employees with privileged access to sensitive systems. The reputational damage extends beyond the victims, as this incident shakes confidence in the professionals responsible for protecting organisations from cybercrime.
As legal proceedings unfold, investigators are expected to uncover further details of how these insiders exploited their access and expertise. The broader cybersecurity community must now re-evaluate its safeguards, particularly regarding insider access, ethical oversight, and third-party vetting.
Organisations are encouraged to strengthen internal monitoring, conduct regular security audits, and ensure that incident response plans are not only robust but also resistant to insider manipulation. This case serves as a reminder that cyber defences are only as strong as the people behind them.
