Necro Trojan Sneaks into Google Play with up to 11m Victims

Published

In late August 2024, Kaspersky experts identified a new version of the Necro Trojan that had infiltrated several popular applications on Google Play and modified applications on unofficial platforms, including Spotify, WhatsApp and Minecraft.

Necro is an Android downloader that downloads and runs other malicious components on infected devices based on commands issued by the Trojan’s creators. Kaspersky’s solutions recorded* Necro attacks targeting users in Russia, Brazil, Vietnam, Ecuador, and Mexico as part of this malicious campaign.

Capabilities of the Necro Trojan 

The variant of Necro discovered by Kaspersky experts can download modules onto infected smartphones that display ads in invisible windows and click on them, download executable files, install third-party applications, and open arbitrary links in invisible WebView windows to execute JavaScript code.

Based on its technical characteristics, the Trojan is also likely capable of subscribing users to paid services. Additionally, the downloaded modules allow attackers to redirect Internet traffic through the victim’s device. This enables cybercriminals to visit prohibited or desired resources using the victim’s device, potentially utilising it as part of a proxy botnet.

Infected Apps on Unofficial Platforms

The first discovery of Necro by company’s experts was in a modified version of Spotify Plus. The creators of the app claimed that it was safe for devices and offered additional features not found in the official music streaming app.

Subsequently, experts also found a modified version of WhatsApp containing the Necro downloader, followed by infected versions of popular games, including Minecraft, Stumble Guys, and Car Parking Multiplayer. Necro was embedded into these applications via an unverified ad module.

Infected Apps on Google Play

The Necro campaign extended beyond third-party platforms and was also discovered on Google Play. The malicious downloader was found in the Wuta Camera app and Max Browser.

According to Google Play statistics, the combined downloads of these apps exceeded 11 million. On this platform, Necro was also distributed via an unverified ad module. Following Kaspersky’s report to Google, the malicious code was removed from Wuta Camera, and Max Browser was taken down from the store. However, users still risk encountering Necro on unofficial platforms.

“Users often download unofficial, modified apps to bypass restrictions in official applications or to access additional free features. Cybercriminals exploit this behaviour, spreading malware with these apps as there is no moderation on third-party platforms,” comments Dmitry Kalinin, cybersecurity expert at Kaspersky.

“It is also noteworthy that the version of Necro embedded in these applications used steganography techniques, hiding its payload within images to remain undetected – a very rare method for mobile malware.”

Kaspersky Cybersecurity Experts Warn of Evolving Holiday Scams

Kindly share this post

With the holiday season here, it’s not only a time for magic and celebration but also a prime opportunity for fraudsters to exploit the festive rush for gifts and bargains.

Kaspersky Cybersecurity Experts Warn of Evolving Holiday Scams

Amid the sparkle of year-end celebrations, cybersecurity experts at Kaspersky have identified several prominent scams targeting consumers across various regions and languages.

Fake holiday shops

Deceptive online stores mimic the look and feel of legitimate e-commerce sites, offering seasonal items such as decorations, gifts, and even trees at steep discounts.

These sites often appear highly localised, adapting their language and currency based on the user’s geographic location, leveraging data extracted from browsers.

Victims typically encounter these stores by following links in ads or pop-ups.

These sites aim to steal funds. Often, these fraudulent stores exist only for a short period, as they get flagged by the vendors of goods.

Free mobile data offer

This scam plays on the allure of free services, claiming to provide free mobile data valid across all major telecom providers.

In order to receive the free data, victims are required to share the promotion link with 10–15 contacts via WhatsApp, ensuring the scam spreads exponentially.

After sharing, victims are prompted to enter their personal details — name, phone number, and email — into a form.

The collected data is then sold on the Dark Web or used in other fraudulent activities.

In some cases, victims unknowingly download malware that compromises their devices, leading to further exploitation.

Holiday payments on behalf of government agencies

Fraudsters impersonate government authorities, promising fictitious payments in celebration of the holidays.

This scam has been reported in several African countries, including Kenya and Nigeria.

To receive payment, victims are directed to fill out a survey which requires personal details like name and phone number.

Once the survey is completed the user is asked to share the link to the announcement with their connections via WhatsApp.

These details are collected and added to fraudulent databases, then sold to third parties or used for phishing attacks and identity theft.

This scam exploits trust in government systems and the festive spirit of giving.

Christmas recipe scam

This scam begins with a seemingly harmless email promoting a holiday cake recipe.

Victims are encouraged to pay a small fee to access the recipe.

Once payment is made, the victim’s credit card information is stolen. The fraudsters also collect other personal information essential for accessing banking services.

“Holiday scams are not a new phenomenon, but they have evolved to become increasingly sophisticated, leveraging regional traditions and technology to exploit unsuspecting victims.

The rush of the holidays makes people more vulnerable — they’re distracted, eager to grab a deal, or trust promotions that align with festive themes. Cybercriminals are not just stealing money — they’re building massive databases of personal information that fuel future fraudulent schemes.

The holiday season is a time for joy and giving, but users need to remain vigilant to ensure they’re not unknowingly giving fraudsters the tools to exploit them further,” said Olga Svistunova, Senior Web Content Analyst at Kaspersky.

Cybercriminals have persisted in targeting Nigerian government websites, with the most recent attack on the National Bureau of Statistics (NBS).

Hackers Seize NBS Newly Redesigned Website

The NBS confirmed the development in a brief statement posted on its X (formerly Twitter) account

It said that its newly redesigned official website has been hacked.

The NBS disclosed the incident and assured the public that efforts are underway to recover the website.

It urged the public to disregard any messages or reports posted until the full recovery of its website.

The statement on X read: “This is to inform the public that the NBS website has been hacked, and we are working to recover it. Please disregard any message or report posted until the website is fully restored.”

The NBS plays a vital role in Nigeria’s development, serving as the official statistical agency responsible for collecting, analyzing, and disseminating statistical data on the country’s economy, governance, and development

This marks the latest in a series of attacks on Nigerian government websites, a trend that has been ongoing for some years.

From government ministries to officials, cyberattacks in Nigeria have surged to alarming levels, with even financial institutions falling victim.

The Nigerian Communications Commission (NCC) and National Information Technology Development Agency (NITDA) frequently issue warnings of cybercriminals targeting individuals, government entities, banks, and telecom companies.
