ATTACKS & VULNERABILITIES

TLDR InfoSec

GITHUB COPILOT CHAT FLAW LEAKED DATA FROM PRIVATE REPOSITORIES

A vulnerability in GitHub Copilot Chat allowed attackers to combine Content Security Policy bypass with remote prompt injection to leak sensitive data from private repositories, including AWS keys and zero-day vulnerabilities. The attack exploited hidden HTML comments and GitHub's Camo proxy system by creating a dictionary of pre-generated Camo URLs for each alphabet character, allowing data to be exfiltrated when victims clicked on malicious URLs. GitHub addressed the issue on August 14 by preventing Camo from being used to leak sensitive user information.

CYBERCRIME OBSERVATIONS FROM THE FRONTLINES: UNC6040 PROACTIVE HARDENING RECOMMENDATIONS

UNC6040 is a financially motivated threat group that uses voice phishing (vishing) to trick employees into authorizing malicious Salesforce Data Loader applications, enabling large-scale data theft from corporate Salesforce instances. The attackers impersonate IT support personnel to manipulate victims into granting OAuth access to fake connected apps, then systematically exfiltrate sensitive data using legitimate Salesforce tools. Organizations should implement phishing-resistant MFA, restrict API access to approved applications only, enforce network-based login restrictions, and deploy real-time detection rules that monitor for suspicious OAuth authorizations followed by bulk data exports.

ORACLE E-BUSINESS SUITE ZERO-DAY EXPLOITED IN WIDESPREAD EXTORTION CAMPAIGN

A threat actor linked to the CL0P group exploited a previously unknown vulnerability in Oracle E-Business Suite, stealing sensitive data from targeted organizations and launching a mass extortion email campaign. Attackers leverage sophisticated multi-stage Java payloads and compromised third-party accounts. Although Oracle issued critical emergency patches to mitigate the risk, this is still being actively exploited.

MICROSOFT: WINDOWS BACKUP NOW AVAILABLE FOR ENTERPRISE USERS

Microsoft's Windows Backup for Organizations is an enterprise-grade backup tool that backs up Windows settings, preferences, and Microsoft Store apps to Exchange Online cloud storage, simplifying Windows 10 to Windows 11 migrations. The feature is opt-in and disabled by default, requiring IT administrator configuration through backup and restore policy settings on Entra-joined devices. Microsoft encrypts the backed-up data but retains access for troubleshooting and legal compliance purposes under strict management oversight.

BROKEN AUTHORIZATION IN APIS: INTRODUCING AUTOSWAGGER

Intruder's Autoswagger is a free open-source tool that automatically scans APIs for authorization vulnerabilities by parsing OpenAPI/Swagger documentation to identify endpoints lacking proper authentication checks. The tool discovered critical security flaws across major organizations during bug bounty testing, including exposed credentials, customer data, and database access at companies like Microsoft, multinational tech firms, and beverage corporations. Autoswagger highlights how self-documenting APIs increase attack surface by providing attackers with detailed endpoint information, making these simple authorization weaknesses easier to exploit at scale.

CALIFORNIA ENACTS LAW GIVING CONSUMERS ABILITY TO UNIVERSALLY OPT OUT OF DATA SHARING

California Governor Gavin Newsom signed a law requiring browsers to make it easier for Californians to opt out of allowing third-party data sharing. The California Consumer Privacy Act (CCPA) requires websites to allow Californians to opt out of data sharing, but it also mandates that browsers universally support this. Previously, this had to be done using third-party extensions.
