CTM360 Reveals Global WhatsApp Account-Hacking Campaign

🔒 CTM360 reports a large-scale campaign, dubbed HackOnChat, that deploys deceptive web portals and impersonation pages to compromise WhatsApp accounts worldwide. Attackers rapidly create thousands of malicious URLs on inexpensive domains and web-building platforms, luring users with fake security alerts and lookalike login pages. Once accounts are taken, they are abused to defraud contacts, harvest sensitive data, and expand the scam.

Sturnus Android Trojan Steals Messages and Controls Devices

🔒Sturnus is a new Android banking trojan discovered by ThreatFabric that can capture decrypted messages from end-to-end encrypted apps like Signal, WhatsApp, and Telegram. It abuses Accessibility services and on-screen capture to read message content and deploys HTML overlays to harvest banking credentials. The malware also supports real-time, AES-encrypted VNC remote control and obtains Android Device Administrator privileges to resist removal while targeting European financial customers with region-specific overlays.

WhatsApp flaw allowed discovery of 3.5B registered numbers

🔍 Researchers from the University of Vienna and SBA Research found a flaw in WhatsApp's contact discovery that let them enumerate valid numbers globally, confirming about 3.5 billion registered accounts. By abusing the lookup mechanism they could probe numbers across 245 countries at rates exceeding 100 million checks per hour from a single IP. The technique also exposed public (non-private) keys, timestamps, profile photos and About text, enabling inference of device OS, account age and linked secondary devices, prompting Meta to add rate limits and tighter visibility rules.

Python WhatsApp Worm Spreads Eternidade Stealer Across Brazil

📲 Trustwave SpiderLabs describes a Python-based WhatsApp worm that propagates a Delphi credential stealer named Eternidade Stealer across Brazilian devices. The campaign begins with an obfuscated Visual Basic Script dropper that installs both a Python WPPConnect-based propagator and an MSI/AutoIt installer which injects the stealer into svchost.exe. Operators use IMAP to fetch dynamic C2 addresses and apply Brazilian Portuguese geofencing to limit infections to the target region.

Eternidade Stealer: WhatsApp Worm Targets Brazil's Ecosystem

🔒 Trustwave SpiderLabs has identified Eternidade Stealer, a multi-component banking Trojan that combines a Python-based WhatsApp-propagating worm, a Delphi stealer and an MSI dropper to harvest financial credentials and spread laterally. The campaign uses an obfuscated VBScript to deliver two payloads, dynamically retrieves command-and-control via IMAP and activates only on systems using Brazilian Portuguese. Defenders should watch for unexpected MSI or script executions, suspicious WhatsApp messages and indicators linked to the campaign.

Meta Expands WhatsApp Security Research Effort

🛡️ Meta has provided selected long‑time bug bounty researchers with a new tool, WhatsApp Research Proxy, to streamline analysis of WhatsApp's network protocol and reduce barriers to in‑depth research. The company is also running a pilot that invites research teams to focus on platform abuse with internal engineering and tooling support.

Maverick Banking Malware Spreads via WhatsApp Web in Brazil

⚠️ Threat hunters report a .NET banking trojan dubbed Maverick propagating via WhatsApp Web, with analyses noting significant code overlaps with the Coyote family and attribution to the actor known as Water Saci. The campaign uses a self-propagating component named SORVEPOTEL to distribute a ZIP containing an LNK that launches PowerShell/cmd to fetch loaders from zapgrande[.]com. The loader installs modules only after geo/linguistic checks confirm the victim is in Brazil and then deploys banking-targeted credential-stealing and web-injection capabilities.

LandFall Spyware Abused Samsung DNG Zero-Day via WhatsApp

🔒 A threat actor exploited a Samsung Android image-processing zero-day, CVE-2025-21042, to deliver a previously unknown spyware called LandFall using malicious DNG images sent over WhatsApp. Researchers link activity back to at least July 23, 2024, and say the campaign targeted select Galaxy models in the Middle East. Unit 42 found a loader and a SELinux policy manipulator in the DNG files that enabled privilege escalation, persistence, and data exfiltration. Users are advised to apply patches promptly, disable automatic media downloads, and enable platform protection features.

Samsung Zero-Click Flaw Exploited to Deploy LANDFALL Spyware

🔒 A now-patched out-of-bounds write in libimagecodec.quram.so (CVE-2025-21042, CVSS 8.8) was used as a zero-click vector to deliver commercial-grade Android spyware known as LANDFALL. The campaign appears to have used malicious DNG images sent via WhatsApp to extract and load a shared library that installs the spyware. Unit 42 links activity to targets in Iraq, Iran, Turkey, and Morocco and notes samples dating back to July 2024. The exploit also deployed a secondary module to modify SELinux policy for persistence and elevated privileges.

WhatsApp screen-sharing scam: risks and protections

🔒 A growing scam exploits WhatsApp’s screen-sharing feature to trick users into exposing verification codes, passwords and banking details during video calls. Attackers pose as banks, service providers or contacts, create urgency, then request screen sharing or the installation of remote-access apps like AnyDesk or TeamViewer. Once granted, they capture OTPs, install malware or coerce transfers, enabling account takeover and financial theft. Stay skeptical: never share screens, passwords or verification codes with strangers.

WhatsApp Adds Passwordless Passkey Chat Backups now

🔒 WhatsApp is rolling out passkey-encrypted chat backups on iOS and Android, allowing users to secure backups with biometrics or a device screen lock instead of a password. Passkeys rely on a device-generated private/public key pair so the private key never leaves the device, reducing exposure to credential theft. Users can enable the feature under Settings > Chats > Chat backup > End-to-end encrypted backup. Meta has begun a global rollout that will reach users over the coming weeks and months.

Privacy rankings of popular messaging apps — 2025 Report

🔒 Incogni's Social Media Privacy Ranking 2025, summarized by Kaspersky, evaluates 15 platforms across 18 criteria to compare messaging apps on privacy and data handling. Overall scores place Discord, Telegram and Snapchat near the top, but a subset of practical criteria ranks Telegram first, followed by Snapchat and Discord. The analysis highlights default settings, data collection by mobile apps, handling of government requests, and encryption differences, noting that only WhatsApp provides end-to-end encryption for all chats by default.

Meta launches new anti-scam tools for WhatsApp, Messenger

🛡️ Meta is rolling out new anti-scam features for Messenger and WhatsApp to help users detect and avoid fraud.

WhatsApp will display warnings about screen-sharing with unknown callers. These protections are enabled by default.

Meta Adds Scam Warnings to WhatsApp and Messenger Apps

🔒 Meta is rolling out new anti-scam features for WhatsApp and Messenger. On WhatsApp, users will receive warnings when attempting to share their screen with unknown contacts during video calls to help prevent accidental exposure of bank details or verification codes. On Messenger, an opt-in Scam detection setting flags potentially suspicious messages from unknown senders; detection runs on-device to preserve end-to-end encryption unless users choose to submit recent messages for AI review, which removes E2EE. Meta also said it has taken action against thousands of impersonating pages and disrupted millions of accounts tied to organized scam centers.

131 Chrome Extensions Hijack WhatsApp Web for Spam

🔍 Cybersecurity researchers uncovered a coordinated operation that used 131 rebranded Chrome extensions—about 20,905 active users—to inject automation code into WhatsApp Web and conduct large-scale spam campaigns targeting Brazilian users. Socket found the add-ons share a common codebase, design patterns, and infrastructure and are primarily published under WL Extensão variants. The extensions pose a high spam risk by automating bulk outreach and scheduling to evade WhatsApp rate limits and violate Chrome Web Store policies.

WhatsApp-Based Self-Spreading Malware Hits Brazil Nationwide

⚠️ Trend Micro has uncovered a self-propagating malware campaign named SORVEPOTEL that primarily targets Brazilian Windows users via WhatsApp. The attack is delivered through convincing phishing messages with malicious ZIP attachments that contain LNK shortcuts which trigger PowerShell to download a batch payload. The payload establishes persistence by copying itself to the Windows Startup folder and contacts a command-and-control server, and if WhatsApp Web is active the malware automatically forwards the infected ZIP to contacts and groups, causing rapid spread and frequent account bans. Researchers report no evidence of data exfiltration or file encryption so far.

WhatsApp phishing: fake vote pages hijack accounts

🔒 Kaspersky analyzed a global phishing campaign that uses convincing fake voting pages to hijack WhatsApp accounts. Attackers lure victims with personalized requests and multilingual scam pages; when users click Vote they’re prompted for the phone number linked to their account and shown a single‑use verification code. Victims who then enter or paste that code in their WhatsApp app inadvertently activate a remote WhatsApp Web session, giving attackers full access. Immediately check Linked devices, disconnect unknown sessions, and follow Kaspersky’s recovery and prevention guidance.

🔒 The article argues that personal threat modeling must adapt as governments increasingly combine their extensive administrative records with corporate surveillance data. It details what kinds of government-held data exist, how firms augment those records, and the distinct dangers of targeted versus mass surveillance. Practical mitigations are discussed—encryption, scrubbing accounts, burner devices—and the piece stresses that every defensive choice is a trade-off tied to individual goals.

WhatsApp Adds Message Translation to iPhone and Android

🌐 WhatsApp has begun rolling out a new message translation feature for Android and iPhone that translates messages in chats, groups, and channel updates. On iOS, users can translate individual messages via long-press and tapping 'Translate', while Android users can also enable automatic translation to convert all messages in a thread. Initial language support differs by platform and the rollout will be gradual.

Whistleblower Lawsuit Alleges WhatsApp Security Failures

🛡️ Attaullah Baig, former head of security at WhatsApp, has filed a whistleblower lawsuit alleging that Facebook knowingly failed to fix multiple security flaws in breach of its 2019 settlement with the FTC. The complaint asserts that in 2022 roughly 100,000 accounts were compromised daily, rising to as many as 400,000 daily lockouts by last year, and that inadequate anti-scraping protections exposed profile data at scale. Baig invokes the whistleblower-protection provisions of the Sarbanes-Oxley Act, and the filing has prompted wider media coverage and potential regulatory scrutiny.
