On 31 May 2021, JBS disclosed Ransomware issues under the banner "JBS Hit by Major Ransomware Attack Linked to Russia, Disrupting Global Meat Supply".
The world’s largest meat processing company, JBS, suffered a sophisticated ransomware attack that forced the temporary shutdown of operations in Australia, Canada, and the U.S., disrupting a significant portion of global meat production.
The disruption is felt across the environment, affecting IT systems, meat processing operations.
In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Suspended affected systems, and began remediation that includes Restoring operations using backup servers, while recovery efforts such as Most plants expected to resume work by Wednesday continue.
The case underscores how Ongoing (FBI investigating), teams are taking away lessons such as Vulnerability of critical food supply chains to cyber threats, with advisories going out to stakeholders covering U.S. officials warned against paying ransoms; Russia engaged in discussions.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
