In this segment of the video, it is discussed that a supply chain attack targeted companies using the IT management software, Casia, leading to potential ransomware executions. Over 1,000 companies out of 40,000 that use the software are believed to be affected by the attack. The attack’s impact is magnified as many small to medium-sized companies rely on management service providers for their IT needs. The attack primarily focused on the Casia VSA unified remote management platform, giving hackers access to monitor and manage endpoints, network devices, printers, and automate IT processes.

In this segment of the video, it discusses how a supermarket chain in Sweden was compromised by malware, leading to disruptions in their operations. Some were forced to use alternative payment methods like Apple Pay or Samsung Pay due to issues with credit card processing. Samples of the malware are available for analysis, showing similarities between two binaries with added padding to make the file larger and bypass antivirus systems. The malware was loaded through a vulnerability in older versions of Microsoft Defender, utilizing a DLL search order hijack method.

In this segment of the video, it is explained that a vulnerability in Microsoft Defender allows an attacker to load a malicious DLL before the legitimate one, potentially bypassing user account control and escalating privileges. The malware also enables network discovery for spreading to other systems. The cyber attack is likely attributed to the hacker group Rival, known for offering ransomware as a service. The attack used a ransom note and domain linked to Rival. The malware also contains a whitelist function to spare users with a Russian keyboard layout. This tactic aligns with Rival’s previous attacks, suggesting they were also behind the attack on a major meat supplier.

In this part of the video, it is discussed how a supply chain attack affected multiple companies, leading to ransom demands varying based on the size and scale of the compromised entities. Initially, individual ransoms were being sent to affected companies, but now a global decryption key is offered for $50 million to unlock all compromised machines worldwide. This attack marks one of the largest ransomware attacks executed by a hacker group. It is highlighted that having secure offline backups is crucial to protect data from such attacks, as hackers often infiltrate systems in advance to compromise files. Having offline backups can help avoid paying hefty ransom amounts to unlock data.
