Web Skimming
Web skimming, also known as e-skimming or Magecart attacks, is a cyberattack where malicious code is injected into a website's checkout or payment page to steal sensitive customer information, such as credit card details, names, addresses, and even login credentials. This stolen data is then transmitted to the attacker, often to be sold on the dark web or used for fraudulent purposes.
How ThreatNG Helps Combat Web Skimming
ThreatNG's comprehensive capabilities make it a valuable asset in detecting and mitigating web skimming risks:
Superior Discovery and Assessment:
Domain Intelligence: Uncovers subdomains and potential vulnerabilities in the organization's website structure, highlighting potential entry points for skimming code.
Web Application Hijack Susceptibility: This assesses explicitly the risk of a website being compromised and injected with malicious code, such as web skimmers.
Sensitive Code Exposure: This feature detects exposed secrets, such as API keys, in code repositories that attackers could use to gain unauthorized access to the website and inject skimming code.
Search Engine Exploitation: Finds leaked sensitive information related to the website that might signal a compromise or presence of skimmers.
Technology Stack: Identifies the website's specific technologies, allowing targeted analysis for known vulnerabilities exploited by web skimming attacks.
Application Discovery: This process identifies all web applications associated with the organization, providing a comprehensive overview of potential targets for web skimming.
Web Application Firewall Discovery: This detects whether the organization uses a WAF, which could help prevent web skimming attacks. ThreatNG can assess the WAF configuration for effectiveness.
Continuous Monitoring:
Dark Web Presence: Monitors for mentions of the organization or its website on the dark web, signaling potential compromises or stolen data being offered for sale.
Social Media: Tracks brand mentions and sentiment to identify reports or discussions about potential web skimming incidents.
Archived Web Pages: Detects archived web page code changes, revealing unauthorized modifications that could indicate injected skimming code.
Intelligence Repositories:
Compromised Credentials: Alerts on leaked credentials that could be used to gain unauthorized access to the website's backend to inject skimming code.
Working with Complementary Solutions
ThreatNG complements and integrates with other security solutions, such as:
Web Application Firewalls (WAFs): WAFs protect against web application attacks, including skimming attempts. ThreatNG can help prioritize patching vulnerabilities identified by WAFs and assess their overall configuration.
Content Security Policy (CSP): CSP is a browser-based security mechanism that can prevent unauthorized scripts from executing, which can help mitigate web skimming. ThreatNG can assess the organization's CSP implementation for effectiveness.
Client-side Security Solutions: These solutions monitor website traffic on the client-side (user's browser) and can detect anomalies that might indicate the presence of a web skimmer. ThreatNG can complement these solutions by providing a broader view of the website's security posture.
Example: Detecting Web Skimming
ThreatNG's Domain Intelligence discovers a suspicious new script loaded on the checkout page.
Continuous Monitoring of archived web pages reveals that this script wasn't present in previous versions of the page.
Dark Web Presence monitoring discovers an offer to sell credit card data related to the organization's customers.
ThreatNG alerts the security team, providing details about the suspected skimming activity and potential data leakage. The team can then take immediate action to remove the malicious script, investigate the breach, and notify affected customers.
ThreatNG's powerful combination of discovery, assessment, continuous monitoring, and intelligence capabilities makes it a valuable asset in combating web skimming. By proactively identifying vulnerabilities and monitoring for suspicious activity, ThreatNG enables organizations to detect and respond to web skimming attacks swiftly, minimizing potential financial and reputational damage.
