The incident also affected the surveillance camera network of the company along with the finance department. Media speculate that the attack described in the DART report is the one that hit the city of Allentown, Pennsylvania in February 2018.Īt the time, the city paid nearly $1 million to Microsoft to clean out their systems, with an initial $185,000 emergency-response fee stop malware from spreading and up to $900,000 in recovery operations. Now, as they watched their computers blue-screen one by one, they didn’t have any idea what to do next.” “He’d been told the organization had an extensive system to prevent cyberattacks, but this new virus evaded all their firewalls and antivirus software. ‘We want to stop this hemorrhaging,’ an official would later say,” states DART case study report. “When the last of their machines overheated, Fabrikam knew the problem had officially spun out of control. The internal staff was not able to restore the internal systems that were overheating, experts observed the machines freezing and rebooting, while Internet connections were slightly slowing down. The malware made lateral movements by stealing admin account credentials, and in just eight days after the initial infection, the Fabrikam’s entire network was shut down. Microsoft’s DART was involved in the incident response activities eight days after the first device on Fabrikam’s network was compromised. Threat actors also used these credentials to send phishing emails to other Fabrikam employees and to their external contacts in the attempt to infect the largest number of systems as possible. The virus avoided detection by antivirus solutions through regular updates from an attacker-controlled command-and-control (C2) infrastructure, and spread through the company’s systems, causing network outages and shutting down essential services for nearly a week.”Īttackers stole the employee’s user credentials and five days later used them to deliver and execute the Emotet payload. “After a phishing email delivered Emotet, a polymorphic virus that propagates via network shares and legacy protocols, the virus shut down the organization’s core services.

In the report 002, we cover an actual incident response engagement where a polymorphic malware spread through the entire network of an organization.” reads the Microsoft DART announcement. “We are glad to share the DART Case Report 002: Full Operational Shutdown.
