ATTACKS & VULNERABILITIES

TLDR InfoSec

HACKING GROUP CLAIMS THEFT OF 1 BILLION RECORDS FROM SALESFORCE CUSTOMER DATABASES

A hacking group known by several names, including Scattered Spider and ShinyHunters, claims to have stolen approximately a billion records from companies using Salesforce cloud databases. The group is extorting victims with threats to leak stolen data unless ransoms are paid. Multiple major companies are affected. Salesforce denies any breach of its platform or vulnerabilities in its systems.

RESEARCHERS WARN OF SELF-SPREADING WHATSAPP MALWARE NAMED SORVEPOTEL

SORVEPOTEL is a self-propagating malware campaign targeting Brazilian users that spreads through WhatsApp by exploiting social trust and sending malicious ZIP file attachments disguised as receipts or health app files. The attack chain begins with phishing messages from compromised contacts, which leads victims to open Windows shortcut files that execute PowerShell scripts to download payloads from external servers and establish persistence via the Windows Startup folder. Once installed, the malware automatically detects active WhatsApp Web sessions and mass-distributes the malicious ZIP files to all contacts and groups, prioritizing rapid propagation over data theft and frequently resulting in account bans due to spam violations.

POINTER LEAKS THROUGH POINTER-KEYED DATA STRUCTURES

Google Project Zero demonstrated a novel technique to remotely leak memory addresses without memory safety violations by exploiting pointer-keyed data structures in Apple's NSKeyedArchiver serialization. The attack works by crafting specific NSDictionary objects with carefully chosen NSNumber keys to control hash bucket placement, then using the serialized ordering of an NSNull singleton (whose hash is its memory address) to determine its location in the shared cache. While theoretical and requiring a deserialize-reserialize attack surface, this technique demonstrates how pointer-based hashing in keyed data structures can leak addresses even without timing attacks. Organizations should audit serialization endpoints and consider using keyed hash functions instead of raw pointer addresses for object hashing.

SIGNAL PROTOCOL AND POST-QUANTUM RATCHETS

Signal's Sparse Post Quantum Ratchet (SPQR) is part of a new "Triple Ratchet" protocol that combines its existing Double Ratchet with quantum-resistant ML-KEM cryptography to protect against future quantum computing threats while maintaining forward secrecy and post-compromise security. The implementation uses erasure coding and state machines to efficiently transmit large ML-KEM keys (over 1,000 bytes) in small chunks, includes a graceful downgrade mechanism for backward compatibility during rollout, and employs formal verification using ProVerif and F* to ensure protocol correctness. Security professionals should note that this represents a practical approach to post-quantum migration, which preserves existing security guarantees while introducing quantum resistance. The protocol automatically upgrades conversations without requiring user intervention.

VED 2026: AFTER CFI - DATA ONLY

Modern kernel privilege escalation attacks have shifted from traditional control flow methods like ROP to more stealthy, stable data-only attacks that bypass Control Flow Integrity (CFI), prompting the development of advanced defense systems like VED (Vault Exploit Defense). Novel techniques, such as DirtyPipe, cred-jar heap spray, and pipe primitives, exploit weaknesses in kernel memory handling to corrupt authentication data or page buffers, directly overwriting critical structures, including credential jars and pipe buffers, while evading detection by typical CFI solutions. VED counters these threats through multiple integrity measures, including shadow data tracking, hash monitoring, slab poisoning, and specialized protections for core patterns and pipe buffers, aiming to detect stealthy modifications and strengthen kernel security against increasingly sophisticated data-centric exploits while minimizing performance impact.

GREYNOISE DETECTS 500% SURGE IN SCANS TARGETING PALO ALTO NETWORKS PORTALS

GreyNoise detected a 500% surge in scanning activity targeting Palo Alto Networks login portals on October 3, with over 1,285 IP addresses (93% suspicious and 7% malicious) conducting coordinated reconnaissance that mirrors previous Cisco ASA scanning patterns and shares TLS fingerprints linked to Netherlands infrastructure, potentially signaling upcoming vulnerability disclosures since historical patterns show Palo Alto scan spikes often precede new flaw announcements within six weeks.

COMETJACKING: ONE CLICK CAN TURN PERPLEXITY'S COMET AI BROWSER INTO A DATA THIEF

CometJacking affects Perplexity's Comet AI browser by allowing attackers to use a malicious link to inject hidden prompts and steal sensitive user data, such as emails and calendars, by exploiting the browser's own access. Experts warn that this demonstrates the broader risks of AI-driven browsers and have urged stricter agent prompt security to prevent future data theft campaigns
