Vulnerabilities exploited

1 CVE Mallory has correlated with this family across public research and vendor advisories. Each row links to the full Mallory page for that vulnerability.

1 CVES
CVE-2023-4863Heap Buffer Overflow in libwebp WebP Decoder

The code also includes specific routines for browser exploitation (such as targeting CVE-2023-4863), uses a hardcoded Discord webhook for data exfiltration and displays a ransomware WinLocker screen demanding Bitcoin. | This particular sample that Check Point uncovered is a Python Flask application that targets Android users. It’s named InfernoGrabber 9000, and VirusTotal calls it a “fully functional information stealer and ransomware toolkit.”

MITRE ATT&CK

Techniques & procedures

10 distinct techniques documented for this family, organized by ATT&CK tactic.

Initial Access

1 technique
T1566PhishingEvidence1

Instead, it uses social engineering - tricking a user into clicking on a malicious button - combined with a legitimate permission prompt exposed by the File System Access API in Chrome.

Execution

2 techniques
T1203Exploitation for Client ExecutionEvidence1

The code also includes specific routines for browser exploitation (such as targeting CVE-2023-4863)

T1204User ExecutionEvidence1

The code presents a victim-facing lure disguised as a Discord avatar AI upscaler. Clicking on the lure is intended to execute a slew of silent, harmful actions that run entirely inside the browser process.

Stealth

1 technique
T1027Obfuscated Files or InformationEvidence1

What's most concerning is that code obfuscation used in these attacks makes them difficult to spot, so there's a real possibility that attacks using this technique are already occurring in the wild but going unnoticed.

Credential Access

2 techniques
T1056.001KeyloggingEvidence1

These include stealing Discord tokens, harvesting credit card numbers and cryptocurrency seed phrases, logging keystrokes, and capturing unauthorized webcam and microphone feeds.

T1539Steal Web Session CookieEvidence1

These include stealing Discord tokens, harvesting credit card numbers and cryptocurrency seed phrases, logging keystrokes, and capturing unauthorized webcam and microphone feeds.

Collection

3 techniques
T1056.001KeyloggingEvidence1

These include stealing Discord tokens, harvesting credit card numbers and cryptocurrency seed phrases, logging keystrokes, and capturing unauthorized webcam and microphone feeds.

T1123Audio CaptureEvidence1

These include stealing Discord tokens, harvesting credit card numbers and cryptocurrency seed phrases, logging keystrokes, and capturing unauthorized webcam and microphone feeds.

T1125Video CaptureEvidence1

These include stealing Discord tokens, harvesting credit card numbers and cryptocurrency seed phrases, logging keystrokes, and capturing unauthorized webcam and microphone feeds.

Exfiltration

1 technique
T1567Exfiltration Over Web ServiceEvidence1

The code also includes specific routines for browser exploitation (such as targeting CVE-2023-4863), uses a hardcoded Discord webhook for data exfiltration and displays a ransomware WinLocker screen demanding Bitcoin.

Impact

1 technique
T1486Data Encrypted for ImpactEvidence1

The team had to remove some of the more explicit terms - like ransomware - from the prompt, but ultimately produced the same functionality: 'a web page that asks the user for access to local files, processes them inside the browser, and leaves the user unable to recover the original content.'
