Discord Invite Link Hijacking: A New Threat

A recent malware campaign is leveraging vulnerabilities in Discord’s invitation system to distribute the AsyncRAT remote access trojan and a new information stealer known as Skuld. This attack, reported by Check Point, reveals how attackers can redirect users via hijacked invite links to malicious servers, posing serious risks to cybersecurity.

Key Details

• Who: Attackers exploiting Discord’s invite mechanisms; Check Point researchers reported the findings.
• What: Skuld and AsyncRAT malware are being used, targeting sensitive information, particularly related to cryptocurrency.
• When: The discovery comes on the heels of other phishing campaigns earlier this year.
• Where: Primarily affects users on Discord across various regions, including the US and Europe.
• Why: The exploitation of expired or deleted links in Discord allows attackers to silently redirect users to malicious sites.
• How: By reusing old invite codes attached to vanity links, users unknowingly join fake servers, where they are prompted to execute malware disguised as verification steps.

Why It Matters

This threat impacts various facets of IT infrastructure:

• Enterprise Security: Existing security measures could be bypassed if users click on compromised links, leading to unauthorized access.
• Multi-Cloud Strategies: Reliance on platforms like Discord for communication means vulnerabilities can have widespread implications.
• Data Protection: If cryptocurrency-related assets are targeted, policies around data protection need immediate review.

Takeaway for IT Teams

IT professionals should educate users to be cautious with invite links from trusted sources that may become compromised. Consider implementing additional security training and updating access protocols to mitigate risks associated with malicious redirects.
