To Pay or Not to Pay: A Large Retailer Responds to DDoS ExtortionNovember 8, 2018
Fans of The Sopranos or Goodfellas are well-versed in the world of extortion. Whether it is paying off Tony Soprano or Paulie Cicero, the bad guys get their money. Cyber extortion is the digital version of what “wise guys” have been doing for centuries, and there are various tactics threat actors employ.
A large retailer experienced one of the most popular cyber extortion tactics when an executive received an email from a known attack group demanding a large sum of money to prevent a distributed denial of service (DDoS). If they failed to pay by the deadline, the ransom would increase over time. The retailer decided not to pay. What led to that decision and what were the results?
Cyber Extortion through DDoS
When executing a DDoS attack, threat actors set their sights on any organization that relies heavily on its website to generate revenue. This makes retailers ideal targets. The threat actor’s success depends on their capabilities and credibility. While the accessibility of off-the-shelf tools to execute DDoS attacks has lowered barriers to entry, low-credibility, low-capability actors do exist. With business continuity, revenue and brand integrity at stake, navigating an extortion attempt can be agonizing.
To Pay or Not? A High-stakes Decision
Responding appropriately to a DDoS attack threat is impossible without understanding the legitimacy of the attack. There are three main steps that go into making an informed decision about whether to pay the ransom.
Step 1. Gather data from the extortion email – IP address, Bitcoin address (this is usually how the attacker demands payment), and unique strings – and launch an investigation. When it comes to our clients at Digital Shadows, either our analysts help perform these types of investigations on their behalf, or in-house intelligence teams can utilize our Shadow Search tool to perform the investigations themselves.
Step 2. Assess if the actor is who they claim to be and understand their tactics, techniques and procedures (TTPs). At Digital Shadows, we offer an intelligence repository of threat actors, TTPs and events to search against to help determine whether the actor has shown credible capability in the past to carry out a DDoS attack.

Step 3. Based on the findings of the investigation, make an informed decision. In this case, the retailer took action to triage the incident and decided not to comply with the ransom demand. They never experienced a DDoS attack or future extortion demand.
