Weekly Intelligence Summary 04 September 2020

September 4, 2020

Throughout August and into September 2020, a wave of extortion attacks has interrupted operations in the financial services and retail sectors with threats of distributed denial of service (DDoS) if ransom is not paid. The perpetrators claim to be part of known threat groups “APT28” and “Armada Collective” in their ransom letters, which demand Bitcoin payments to prevent DDoS attacks. However, DDoS has apparently occurred regardless of payment, with advanced methods that prolong the attacks’ effects. Victims include the New Zealand stock exchange (NZX), which has likely incurred significant financial losses over the past week as a result. DDoS extortion attacks are a credible threat, despite a greater focus given to ransomware-based extortion threats over the past year.
