GOOGLE UNCOVERS PROMPTFLUX MALWARE THAT USES GEMINI AI TO REWRITE ITS CODE HOURLY

Google identified PROMPTFLUX, an experimental malware, using a hardcoded Gemini API key to query Google's LLM with prompts for code obfuscation and AV evasion. It was able to self-modify and rewrite its source code to evade detection. Believed to be in testing by a financially-motivated actor, the malware includes a "Thinking Robot' that logs AI responses, persists via Windows Startup, and attempts propagation through drives and network shares, though it currently has no real attack capabilities. Security teams should monitor LLM-assisted malware like other variants, implement API key rotation, and be aware of threat actors bypassing AI safety via social engineering.

OAUTH DEVICE CODE PHISHING: AZURE VS. GOOGLE COMPARED

Device code phishing exploits OAuth 2.0's legitimate device authorization flow to steal access tokens by tricking victims into authenticating attacker-generated device codes, with Microsoft Azure allowing attackers to request powerful scopes (including Primary Refresh Tokens) through undocumented "Family of Client IDs" while Google severely restricts device flow to only YouTube and Google Drive scopes. Azure's implementation enables attackers to use legitimate Microsoft URLs and APIs throughout the entire attack chain without requiring client authentication, making phishing campaigns highly effective at bypassing MFA and gaining initial access with tokens scoped to Graph API, Intune enrollment, or other sensitive resources. Security teams should implement Conditional Access policies that restrict device code authentication, monitor suspicious device code flow usage patterns in Azure sign-in logs, educate users about the risks of entering codes from unsolicited communications, and consider Google's restrictive scope model as a defensive blueprint for limiting OAuth attack surface.

FIXING THE BLINDSPOT IN ENDPOINT SECURITY

Deploying Mobile Device Management (MDM) solutions to developer endpoints often presents complications, as security tools are sometimes not well-suited to developer workflows. This leads to many organizations putting in extensive exemptions for developer endpoints, significantly weakening their security posture. This post advocates for a developer MDM that operates by injecting visibility using existing agents such as Zscaler and CrowdStrike.

ACUNETIX (PRODUCT)

Acunetix is a comprehensive web application vulnerability scanner that performs in-depth testing of modern, JavaScript-heavy apps, APIs, and traditional web platforms to identify issues such as SQL injection, XSS, and complex logic flaws, all with low false positives through automated verification. It seamlessly integrates into CI/CD pipelines to enable continuous security testing during development and offers compliance reporting for standards such as PCI DSS, HIPAA, GDPR, and OWASP Top 10. Security teams can utilize Acunetix for pre-production assessments, embed it into DevSecOps workflows for early testing, and leverage its API scanning capabilities to secure microservices and GraphQL endpoints that are often missed by traditional scanners.

GOOGLE EXPANDS CHROME AUTOFILL TO PASSPORTS AND LICENSES, BUT IS IT SAFE?

Google Chrome now supports autofill for sensitive documents like passports and driver's licenses, with encryption and user consent. However, security experts warn that this centralizes critical identity data in a vulnerable location, contradicting cybersecurity advice against storing such info in browsers. Malware like Shuyal Stealer targets browser-stored credentials, and Chrome autofill data isn't stored securely. Security teams should advise against storing sensitive IDs in autofill, enforce policies to restrict this in workplaces, monitor for info-stealer malware, and recommend dedicated password managers with stronger encryption instead of browser storage.

CLOUDFLARE SCRUBS AISURU BOTNET FROM TOP DOMAINS LIST

The Aisuru botnet, with hundreds of thousands of compromised IoT devices and 30 Tbps DDoS power, manipulated Cloudflare's domain rankings by switching from Google's 8.8.8.8 DNS to Cloudflare's 1.1.1.1 in October. This caused malicious domains, mainly in the .su TLD, to outrank major companies like Amazon and Google due to massive DNS queries. The incident revealed vulnerabilities in trust-based domain ranking systems, which treat highly-ranked domains as trustworthy, and attackers used mainly US-based compromised devices from ISPs such as AT&T and Verizon. Security teams should monitor DNS connections to the .su TLD, block it if needed, and avoid relying solely on domain popularity for trust, as DNS query volume can be artificially inflated by botnets.
