Joint worldwide advisory warns of evolving social engineering techniques and new DragonForce ransomware deployment concentrating on business amenities
A collaboration of worldwide cybersecurity businesses issued an pressing up to date advisory on July 29, 2025, highlighting the escalating menace posed by the Scattered Spider cybercriminal group, which has intensified assaults in opposition to important infrastructure and business amenities sectors with more and more subtle techniques and new ransomware variants.
The joint advisory, launched by the Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Safety Company (CISA), Royal Canadian Mounted Police (RCMP), Australian Alerts Directorate’s Australian Cyber Safety Centre (ACSC), Australian Federal Police (AFP), Canadian Centre for Cyber Safety (CCCS), and United Kingdom’s Nationwide Cyber Safety Centre (NCSC-UK), offers complete techniques, methods, and procedures (TTPs) obtained by way of FBI investigations as not too long ago as June 2025.
Scattered Spider, also referred to as UNC3944, Scatter Swine, Oktapus, Octo Tempest, Storm-0875, and Muddled Libra, has considerably developed for the reason that advisory was initially printed in November 2023.
The group, which primarily consists of native English audio system believed to function from the USA, the UK, and Canada, has change into one of the crucial subtle social engineering operations concentrating on giant enterprises.
“Scattered Spider menace actors usually have interaction in knowledge theft for extortion and in addition use a number of ransomware variants, most not too long ago deploying DragonForce ransomware alongside their normal TTPs,” the advisory states. “Whereas some TTPs stay constant, Scattered Spider menace actors typically change TTPs to stay undetected.”
Distribution of MITRE ATT&CK methods employed by Scattered Spider throughout totally different techniques
The group’s hallmark stays its subtle social engineering capabilities, which have change into more and more refined. In contrast to conventional cybercriminals who pose as IT helpdesk employees to focus on workers, Scattered Spider has now reversed this method, impersonating workers to persuade third-party IT and helpdesk personnel to supply delicate info, reset passwords, and switch multi-factor authentication (MFA) tokens to attacker-controlled gadgets.

The group employs a number of assault vectors, together with “push bombing” (overwhelming customers with MFA notifications till they approve entry), subscriber id module (SIM) swap assaults to hijack cellphone numbers, and elaborate vishing campaigns enriched with private info gathered from social media, open-source intelligence, and business intelligence instruments.

ESXi Infrastructure Below Siege
Most regarding is Scattered Spider’s latest deal with VMware ESXi hypervisors, which function important infrastructure for virtualized environments.
In keeping with the advisory, the group has been noticed encrypting VMware ESXi servers utilizing DragonForce ransomware, a tactic that permits them to cripple whole digital machine infrastructures with minimal effort.
The group’s assaults on ESXi environments observe a calculated sample: preliminary entry by way of social engineering, privilege escalation to achieve administrative management, deployment of distant monitoring instruments, and eventually, ransomware execution that encrypts core directories and renders digital machines inoperable.
Current investigations reveal that Scattered Spider has expanded its concentrating on to incorporate Snowflake cloud environments, the place it could possibly exfiltrate huge volumes of information rapidly by operating hundreds of queries instantly upon entry.
The group has additionally been noticed infiltrating firm communications platforms like Slack, Microsoft Groups, and Change On-line to watch safety response efforts and even take part in incident response calls to know how safety groups hunt them.
To take care of persistence and evade detection, the group creates fictitious identities backed by pretend social media profiles, makes use of proxy networks, and continuously rotates machine names. They’ve additionally been noticed exfiltrating knowledge to a number of places, together with MEGA.NZ and U.S.-based knowledge facilities akin to Amazon S3.
The authoring businesses strongly suggest organizations implement phishing-resistant multifactor authentication, keep offline backups saved individually from supply techniques, and deploy utility controls to handle software program execution. Organizations must also improve monitoring for “dangerous logins” and unauthorized account misuse.
With Scattered Spider’s assaults inflicting tons of of tens of millions in damages and their techniques persevering with to evolve, the up to date advisory serves as a important useful resource for organizations looking for to defend in opposition to one in all at the moment’s most subtle cybercriminal operations.
