Scattered Spider Hops Nimbly From Cloud to On-Prem in Complex Attack

November 22, 2023 at 11:56AM

A group known as Scattered Spider, responsible for the MGM cyberattack in September, has conducted another sophisticated ransomware attack. The group exploited a third-party service to gain access to the target organization’s on-premise network. The attack used tactics similar to the MGM attack, including social engineering and manipulation of multi-factor authentication (MFA). Scattered Spider’s abilities pose a significant threat to enterprises, and organizations should prioritize security measures to defend against similar attacks. Law enforcement has been unable to disrupt the group’s activities, highlighting the need for strong defense measures.

Key takeaways from the meeting notes:

1. The group behind the MGM cyberattack has resurfaced in another ransomware attack, demonstrating their ability to target large enterprises through cloud service providers.
2. The attackers used social engineering tactics to obtain valid account credentials and bypass multi-factor authentication (MFA).
3. Once inside the target network, the attackers moved laterally and conducted various nefarious activities, including hijacking Citrix sessions and privilege elevation.
4. Scattered Spider, the threat group, has shown sophistication and operational capability, making them a formidable adversary.
5. Other threat actors could learn from Scattered Spider’s tactics and mount similar attacks, increasing the overall risk.
6. Enterprise defenses should prioritize the principle of least privilege and restrict the super administrator role to mitigate risks associated with Okta credentials.
7. Help desk procedures should include rigorous identity verification processes to prevent social engineering manipulation.
8. Constant vigilance, strengthened security protocols, regular assessments, and staying informed about emerging threats are essential to defend against groups like Scattered Spider.
