Scattered Spider is a threat group that has been operating since at least 2022. They target large companies for huge sums of money…and they’re back in the headlines after the U.S. government put out an advisory about staying safe from Scattered Spider.

In their own words, the FBI and Cybersecurity and Infrastructure Security Agency (CISA) put out this Cybersecurity Advisory “in response to recent activity by Scattered Spider threat actors against the commercial facilities sectors and subsectors. This advisory provides tactics, techniques, and procedures (TTPs) obtained through FBI investigations as recently as November 2023.”

Who Is Scattered Spider?

Scattered Spider, also known as UNC3944, Scatter Swine, or Muddled Libra, is a cybercriminal group that targets large companies and their contracted IT help desks. The group uses a variety of social engineering techniques, including phishing, push bombing, and SIM swapping attacks. Scattered Spider has been active since at least May 2022 and has been linked to several high-profile attacks, including those against Caesars Entertainment and MGM Resorts International.

They primarily target organizations for financial gain, often engaging in data theft and extortion. They exploit vulnerabilities and use remote access tools to avoid detection, and continuously evolve their own strategies and threat arsenal to better compromise target systems.

Behind the New Advisory

So, why is the U.S. government writing up Cybersecurity Advisories about threat groups that have been active for over a year?

The press release contains all of the so-called tactics, techniques, and procedures (what they officially refer to as TTPs) that are the most up-to-date regarding this threat actor group. Not only does it have the most relevant information about who they are targeting, and how; but this report

The FBI and CISA urge organizations to implement the following mitigations to reduce the risk of a Scattered Spider attack:

  • Educate employees about social engineering techniques and how to identify and avoid phishing scams.
  • Follow strong password policies and enable multi-factor authentication (MFA) wherever possible.
  • Monitor networks for suspicious activity and implement security controls to detect and block unauthorized access.
  • Regularly back up data so that it can be restored in the event of a ransomware attack.

The FBI and CISA also encourage organizations to report any suspected Scattered Spider activity to the FBI’s Internet Crime Complaint Center (IC3).
