Scattered Lapsus$ Hunters Take Aim At Zendesk Users – Against Invaders

Scattered Lapsus$ Hunters Take Aim At Zendesk Users - Against Invaders

The Scattered Lapsus$ Hunters group may be targeting Zendesk users in a new campaign, after a fresh batch of phishing domains and malicious helpdesk tickets were discovered, according to ReliaQuest.

The threat intelligence firm said it found over 40 typosquatted Zendesk domains and URLs featuring different organizations’ names or brands(i.e.,organization-zendesk.com) that were created over the past six months.

Some domains, like znedesk[.]com and vpn-zendesk[.]com, host phishing pages like Zendesk single sign-on (SSO) portals designed to harvest credentials.

All domains observed by ReliaQuest were registered through NiceNicand have US and UK registrant information and Cloudflare-masked nameservers.

“These elements are reminiscent of the recent Scattered Lapsus$ Hunters campaign that targeted customer relationship management platform Salesforce in August 2025,” ReliaQuest explained.

“The domains we uncovered while investigating the August campaign shared similarities with the Zendesk domains: formatting, registry characteristics, and the use of deceptive SSO portals.”

The firm also claimed to have evidence that the threat group is submitting fraudulent tickets to Zendesk portals operated by clients of the SaaS customer service platform.

“These fake submissions are crafted to target support and help-desk personnel, infecting them with remote access trojans (RATs) and other types of malware,” it said.

“Targeting help-desk teams with these kinds of tactics often involves well-crafted pretexts, like urgent system administration requests or fake password reset inquiries. The goal is to trick support staff into handing over credentials or compromising their endpoints.”

Discord the First to Fall?

The campaign may already have its first victim, after Discord revealed a breach via a third-party customer service provider last month. Threat actors compromised its Zendesk-based support system, stealing user data including names, email addresses, billing information, IP addressesand government-issued ID information, ReliaQuest said.

The attacks on Zendesk customers follow those targeting Salesforce, Salesloft Driftand Gainsight, described as “high-value SaaS platforms with widespread organizational adoption and access to downstream customer data” by Reliaquest.

However, the Zendesk campaign could also be the work of a copycat group, the companyadmitted.

The security vendor urged organizations to:

  • Require multi-factor authentication (MFA)with hardware security keys, as well as IP allowlistingand session timeout policies for all Zendesk administrative and support accounts
  • Conduct domain monitoring and DNS filteringto detect and block typosquatted Zendesk domains before they can be used in phishing campaigns
  • Secure Zendesk chatby limiting which employees can receive direct messages through it, and deploying content filtering to spot phishing links and credential-request patterns

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
