ATTACKS & VULNERABILITIES

TLDR InfoSec

WHEN THE IMPERSONATION FUNCTION GETS USED TO IMPERSONATE USERS (FORTINET FORTIWEB AUTH. BYPASS CVE-2025-64446)

Fortinet FortiWeb appliances are being actively exploited via CVE-2025-64446, a pre-auth RCE chain combining path traversal and authentication bypass that allows attackers to reach privileged CGI functions and impersonate users by crafting a base64-encoded CGIINFO header containing admin credentials. The vulnerability was silently patched in version 8.0.2 and affects multiple FortiWeb versions. It enables complete appliance compromise through administrative account creation. WatchTowr released a detection tool on GitHub to identify vulnerable hosts.

MAKING SERIALIZATION GADGETS BY HAND - .NET

Creating deserialization gadgets for .NET by hand requires understanding the structure of .NET serialization streams, which are composed of sequential records that define objects and references. By breaking down these records, including headers, class information, member types, and values, it becomes possible to craft custom gadget chains directly in code, without relying on pre-generated payloads or Windows-only tools. The approach presented demonstrates how to reconstruct objects, assign values, and embed complex references, providing insight into the safe and dynamic generation of deserialization payloads.

BE CAREFUL RESPONDING TO UNEXPECTED JOB INTERVIEWS

Attackers are impersonating legitimate recruiters via LinkedIn and email, luring victims with fake job interviews that redirect to malicious sites hosting RMM tools disguised as meeting software updates. The phishing campaign uses social engineering tactics, including spoofed recruiter names from real companies, Gmail sender addresses instead of corporate domains, and shortened URL redirects to phishing infrastructure. Security teams should alert users to verify unsolicited recruitment contacts independently, scrutinize sender domains and meeting URLs, and block known malicious RMM tool distributions through endpoint security controls.

GOOGLE TO FLAG ANDROID APPS WITH EXCESSIVE BATTERY USAGE ON THE GOOGLE PLAY STORE

Google has announced that it will begin flagging apps on the Google Play Store that pass a defined bad behavior threshold. The Android vitals system will track partial wake locks, the cumulative time the app spends with background work while the screen is off, and prevent the device from entering sleep mode. Flagged apps will have a warning on their Play Store page and be excluded from prominent discovery surfaces such as recommendations.
