Chapter 1: The Alert — A Fast-Moving Threat Targeting Indian Users

This is a critical, time-sensitive security alert for all WhatsApp users in India. A new, fast-spreading malware campaign, which we are tracking as the **”LinkLure Worm,”** is actively targeting users across the country. The malware spreads via malicious links sent through WhatsApp messages and is designed to steal your most sensitive personal data, including your entire contact list, all your SMS messages, and all your photos and videos. Due to its worm-like ability to automatically message all of your contacts, this threat is spreading exponentially. Every user must be on high alert.

Chapter 2: The Kill Chain — How the “LinkLure Worm” Infects Your Phone

The Lure: A Deceptive Message

The attack begins with a message from one of your contacts (who is already infected). The message is designed to be enticing and is often localized for Indian audiences, for example: “Hey, check out this exclusive preview of the new ‘Digital India’ benefits program!” or “You won’t believe this video of you!”

The Vector: Sideloading a Malicious APK

The link in the message does not take you to a legitimate website. It takes you to a fake webpage designed to look like an official update page or a special feature portal. This page will prompt you to download and install a new “WhatsApp Gold” or “WhatsApp Premium” application (an APK file). This is the trap. You are being tricked into **sideloading** a malicious application from outside the safety of the Google Play Store.

The Payload: Spyware & a Worm

Once installed, the fake app is a powerful spyware. It will trick you into granting it dangerous permissions, including the ability to read your contacts and SMS messages. It then steals all of this data and, most critically, uses your contact list to automatically send the same malicious message to all of your friends and family, continuing the infection cycle.

Chapter 3: The Defender’s Playbook — An Urgent Action Plan for All Users

If You Have ALREADY CLICKED and Installed the App:

If you suspect you are infected, you must act immediately to contain the damage.

**Disconnect:** Immediately turn off Wi-Fi and Mobile Data on your phone.
**Enter Safe Mode:** Reboot your phone into Safe Mode. This prevents third-party apps, including the malware, from running.
**Uninstall:** In Safe Mode, go to `Settings` > `Apps` and find the suspicious “WhatsApp” update or other unknown app you recently installed. Uninstall it immediately.
**Scan:** Reboot your phone normally and immediately install a reputable mobile security app from the Google Play Store and run a full system scan.
**Change Passwords:** Immediately change the passwords for ALL of your important accounts (email, banking, social media).
**Warn Your Contacts:** Inform your contacts that your phone was infected and they should not click any links they may have received from you.

How to Protect Yourself Proactively:

**NEVER Install Apps from Outside the Google Play Store.** This is the golden rule of Android security.
**Be Skeptical of All Links:** Do not click on suspicious or unexpected links, even if they are from a friend.

Your Digital Bodyguard: A powerful security suite is your essential safety net. **Kaspersky for Android** can detect and block malicious apps, scan dangerous links, and provide a critical layer of defense.

Part 4: The CISO’s Briefing — The BYOD Nightmare

For every CISO, this campaign is a critical case study in the risks of Bring Your Own Device (BYOD). A single employee’s compromised personal phone is now a direct threat to your corporate security. The spyware can intercept MFA codes sent via SMS for your corporate VPN and SaaS applications, and it can steal sensitive corporate data that may be stored in the employee’s photos or personal messages.

A mature security program must have a robust **Mobile Device Management (MDM)** and **Mobile Threat Defense (MTD)** strategy to gain visibility and control over the devices that are accessing corporate data.
