Introduction
PrestaShop, as a widely-used ecommerce platform, is a frequent target for attackers seeking to compromise online shops and their customers. JavaScript injections, particularly obfuscated and “fileless” types are a common method used to evade detection and inflict maximum damage. In this article, we analyze a real-world obfuscated JavaScript snippet discovered on a compromised PrestaShop site, examine its purpose, decode its payload, and provide expert advice on cleaning and securing infected ecommerce environments. We’ll also introduce the MoeSec Website Security Platform to protect your business.
Malware Sample Overview
The following snippet was discovered in a compromised PrestaShop website (often injected into template files, JavaScript files, or even directly into the database):
Key features:
- Stealth: Uses a 1×1 pixel SVG to avoid visual detection.
- Obfuscation: Payload is string-encoded, reversed, and XOR-encrypted.
- Execution: Payload is dynamically evaluated within the browser context.
Threat Explanation
How it works:
- The SVG’s
onloadevent runs obfuscated code. - The payload is decoded at runtime and executed in the browser.
- Can be injected via PHP templates, JavaScript files, or directly into the PrestaShop database (e.g. in CMS content, product descriptions, or configuration options).
Potential Risks:
- Data theft: Credit card skimming, credential theft.
- Redirection: Sending customers to phishing or scam sites.
- Session hijacking: Stealing admin/customer sessions.
- Further infection: Loading additional malware from remote servers.
Through technical analysis and live investigation, it was determined that the decoded JavaScript payload connects to the following malicious server in real time:
wss : // wsocket[.]store/soket
The following malicious domains were found to be involved and used in this malicious campaign and it’s variants:
- jscode[.]cloud
- elementatorprof[.]info
- orristhekyone[.]site
- ghanamusthi[.]xyz
