This incident disrupted programming at Sinclair, impeding the production of local newscasts on multiple days [120386]. (b) The software failure incident has happened again at multiple_organization: The article mentions that Evil Corp, the group behind the ransomware attack on Sinclair Broadcast Group, is known for previous attacks where they stole $100 million from victims around the world by accessing bank account login information. This indicates that Evil Corp has targeted multiple organizations in the past [120386].
Phase (Design/Operation) design, operation (a) The software failure incident at Sinclair Broadcast Group was attributed to a ransomware attack using the Macaw ransomware, which is believed to be a new ransomware from the Russian crime group Evil Corp [120386]. This incident can be linked to the design phase failure as it was caused by malicious code developed by the hackers to disrupt the programming at Sinclair Broadcast Group. (b) The operation phase failure in this incident can be associated with the operation and misuse of the system by the hackers who deployed the ransomware attack on Sinclair Broadcast Group's systems, leading to disruptions in the production of local newscasts [120386].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident at Sinclair Broadcast Group, involving the Macaw ransomware attack, was attributed to a hacking tool similar to malicious code previously used by a Russian crime group known as Evil Corp. The ransomware attack disrupted programming at Sinclair, impeding the production of local newscasts [120386]. The incident was primarily caused by the ransomware infiltrating the company's systems, indicating a failure originating from within the system. (b) outside_system: The ransomware attack on Sinclair Broadcast Group was linked to Evil Corp, a Russian crime group known for its cybercriminal activities. The group has been sanctioned by the US government for its malicious cyber efforts, including stealing millions of dollars from victims worldwide [120386]. This external threat from a known cybercriminal organization highlights the role of factors originating from outside the system in contributing to the software failure incident.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident at Sinclair Broadcast Group was attributed to a ransomware attack using the Macaw ransomware, which is believed to be a new ransomware from the Russian crime group Evil Corp. This non-human action of a ransomware attack disrupted programming at Sinclair, impeding the production of local newscasts [120386]. (b) Human actions were involved in the response to the software failure incident, as Sinclair Broadcast Group has been working closely with a third-party cybersecurity firm, incident response professionals, law enforcement, and governmental agencies to investigate and respond to the ransomware attack. The company has also notified law enforcement and US government agencies about the attack, indicating human involvement in the response efforts [120386].
Dimension (Hardware/Software) software (a) The software failure incident at Sinclair Broadcast Group was not attributed to hardware issues but rather to a ransomware attack. The incident involved the deployment of Macaw ransomware, which is believed to be a new ransomware from the Russian cybercrime group Evil Corp [120386].
