Scattered Spider, a sophisticated cybercriminal group known for employing phishing tactics, has caught the attention of U.S. cybersecurity and intelligence agencies.
U.S. cybersecurity and intelligence agencies have recently released a joint advisory warning about a cybercriminal group called Scattered Spider. This group is notorious for using sophisticated phishing tactics to infiltrate targets and engage in data theft for extortion. The agencies have highlighted the group's recent use of the BlackCat/ALPHV ransomware alongside their usual tactics. Scattered Spider has gained notoriety in the cybersecurity world and was the subject of an extensive profile by Microsoft last month, which referred to the group as “one of the most dangerous financial criminal groups.” In this article, we will delve into the tactics employed by Scattered Spider and explore the measures being recommended by the U.S. government to protect against their activities.
Social Engineering Tactics and Gen Z Cybercrime Ecosystem
Scattered Spider, also known as Muddled Libra, Octo Tempest, 0ktapus, Scatter Swine, Star Fraud, and UNC3944, is considered an expert in social engineering. The group relies on phishing, prompt bombing, and SIM swapping attacks to obtain credentials, install remote access tools, and bypass multi-factor authentication (MFA). It is believed to be part of a larger cybercrime ecosystem, the Com (alternately spelled Comm), associated with violent activity and swatting attacks.
Impersonation and Remote Access Tools
One notable tactic Scattered Spider employs is the impersonation of IT and help desk staff. The group uses phone calls or SMS messages to target employees and gain elevated network access. Once initial access is gained, Scattered Spider deploys legitimate remote access tunneling tools such as Fleetdeck.io, Ngrok, and Pulseway. They also utilize remote access trojans and stealers like AveMaria (aka Warzone RAT), Raccoon Stealer, and Vidar Stealer.
Living-off-the-Land Techniques and Proactive Intrusion
They scattered Spider leverages living-off-the-land (LotL) techniques to evade detection and navigate compromised networks. The group actively joins incident remediation, response calls, and teleconferences to identify how security teams are hunting them and develop new avenues of intrusion in response to victim defenses. This proactive approach makes them a formidable adversary in the cybersecurity landscape.
Affiliation with BlackCat Ransomware Gang
As of mid-2023, Scattered Spider has acted as an affiliate for the BlackCat ransomware gang. This partnership allows them to monetize their access to victims for extortion-enabled ransomware and data theft. The collaboration between these two groups poses an even more significant threat to organizations and individuals targeted by Scattered Spider.
The U.S. government is urging companies to take proactive measures to protect against the activities of Scattered Spider. Implementing phishing-resistant multi-factor authentication (MFA), enforcing recovery plans, maintaining offline backups, and adopting application controls to prevent the execution of unauthorized software on endpoints are some of the recommended steps. As cybercriminal groups like Scattered Spider evolve tactics, organizations must stay vigilant and implement robust cybersecurity measures to safeguard their sensitive information.
