Hackers steal Discord accounts with RedTiger-based infostealer

Discord data targeted by the malware

Attackers are using the open-source red-team tool RedTiger to build an infostealer that collects Discord account data and payment information.

The malware can also steal credentials stored in the browser, cryptocurrency wallet data, and game accounts.

RedTiger is a Python-based penetration testing suite for Windows and Linux that bundles options for scanning networks and cracking passwords, OSINT-related utilities, Discord-focused tools, and a malware builder.

Discord-related tools in RedTigeron GitHub, its free and unconditional distribution and the lack of any safeguards allow easy abuse.

RedTiger's malware buildera report from Netskope, threat actors are now abusing RedTiger”s info-stealer component, primarily for targeting French Discord account holders.

The attackers compiled RedTiger’s code using PyInstaller to form standalone binaries and gave those gaming or Discord-related names.

Once the info-stealer is installed on the victim’s machine, it scans for Discord and browser database files. It then extracts plain and encrypted tokens via regex, validates the tokens, and pulls the profile, email, multi-factor authentication, and subscription information.

Next, it injects custom JavaScript into Discord’s index.js to intercept API calls and capture events such as login attempts, purchases, or even password changes. It also extracts payment information (PayPal, credit cards) stored on Discord.

Discord data targeted by the malware

If you suspect compromise, revoke Discord tokens, change passwords, and reinstall your Discord desktop client from the official site. Also, clear saved data from browsers and enable MFA everywhere.

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.
