ESET Researchers Spot DoubleLocker ‘Innovative’ Android Ransomware

By peter oluka
ESET researchers have spotted the first-ever ransomware misusing Android accessibility services. On top of encrypting data, it also locks the device.
Detected by ESET products as Android/DoubleLocker.A, the ransomware is based on the foundations of a particular banking Trojan, known for misusing accessibility services of the Android operating system.
However, DoubleLocker doesn’t have the functions related to harvesting users’ banking credentials and wiping out their accounts. Instead, it has received two powerful tools for extorting money from its victims.
DoubleLocker can change the device’s PIN, preventing victims from accessing their devices, and also encrypts the data it finds in them – a combination that has not been seen previously in the Android ecosystem.
“Given its banking malware roots, DoubleLocker may well be turned into what could be called ransom-bankers. Two-stage malware that first tries to wipe your bank or PayPal account and subsequently locks your device and data to request a ransom… Speculation aside, we spotted a test version of such a ransom-banker in the wild as long ago as May, 2017,” comments Lukáš Štefanko, the ESET malware researcher who discovered DoubleLocker.
Distribution
DoubleLocker spreads in the very same way as its banking parent does. It is distributed mostly as a fake Adobe Flash Player through compromised websites.
Once launched, the app requests activation of the malware’s accessibility service, named “Google Play Service”. After the malware obtains the accessibility permissions, it uses them to activate device administrator rights and set itself as the default Home application, in both cases without the user’s consent.
“Setting itself as a default home app – a launcher – is a trick that improves the malware’s persistence. Whenever the user clicks on the home button, the ransomware gets activated and the device gets locked again. Thanks to using the accessibility service, the user doesn’t know that they launch malware by hitting Home,” explains Štefanko.
Locking Both Device And Data
DoubleLocker, once executed on the device, creates two reasons for the victims to pay.
First, it changes the device’s PIN, effectively blocking the victim from using it. The new PIN is set to a random value which the attackes neither store nor send anywhere, so it’s impossible for the user or a security expert to recover it. After the ransom is paid, the attacker can remotely reset the PIN and unlock the device.
Second, DoubleLocker encrypts all files from the device’s primary storage directory. It utilizes the AES encryption algorithm, appending the extension “.cryeye”. “The encryption is implemented properly, which means that, unfortunately, there is no way to recover the files without receiving the encryption key from the attackers,” says Štefanko.
The ransom has been set to 0.0130 BTC (approximately USD 54 at time of writing) and the message highlights that it must be paid within 24 hours. However, if the ransom is not paid, the data will remain encrypted and will not be deleted.
How To Get Rid Of It?
In the ransom note, the user is warned against removing or otherwise blocking DoubleLocker: “Without [the software], you will never be able to get your original files back”.
To prevent unwanted removal of the “software”, the crooks even recommend disabling the user’s antivirus software.
“Such advice is irrelevant: all those with a quality security solution installed on their devices are safe from DoubleLocker,” explains Štefanko.
The only viable option to clean the device of the DoubleLocker ransomware is via a factory reset.
For rooted devices, however, there is a method to get past the PIN lock without a factory reset. For the method to work, the device needed to be in the debugging mode before the ransomware got activated.
If this condition is met, then the user can connect to the device by ADB and remove the system file where the PIN is stored by Android. This operation unlocks the screen so that the user can access their device. Then, working in safe mode, the user can deactivate device administrator rights for the malware and uninstall it. In some cases, a device reboot is needed.
As for the data stored on the device, there is no way to recover it, as mentioned earlier.
“DoubleLocker serves as just another reason for mobile users to have a quality security solution installed, and to back up their data on a regular basis,” concludes Štefanko.

Privacy Crisis May Undermine Local Hosting of Data by Banks, Fintechs

Nigeria’s weak data protection guardrails may undermine the recent directive by Central Bank of Nigeria (CBN) to banks, fintech firms, and other payment service providers to store payment transaction data generated within the country local servers.

CBN said that the new rule will start from January 1, 2027, as part of new measures to strengthen oversight of the fast-growing digital payments ecosystem.
This will also provide the country greater control over critical data infrastructure, allowing authorities to easily access records, conduct audits, enforce compliance, and investigate, especially in cases where criminal offenses are involved, reducing delays often caused by intermediation between local and foreign entities.
Apart from data sovereignty, the CBN added that moving transaction records from foreign servers will help drive investments in local data centers and cloud storage capacity.
Though reliable estimates are hard to come by, it is believed that Nigeria loses over N60 billion in hosting data in foreign servers.
But a coalition of civil society organizations (CSOs), has raised concerns over safety measures in place to protect data of Nigerians, despite having data protection laws in place.
The coalition, comprising Media Rights Agenda, Paradigm Initiative, Digital Rights Lawyers Initiative, and Accountability Lab Nigeria, among others, released the “Protected From the State, Not By It: Nigeria’s Data Protection Crisis Is a Crisis of Implementation,” where they criticized regulators’ failure to effectively enforce data protection laws, which led to rising cases of digital fraud and rampant illegal sale of sensitive information.
There have been leaks of sensitive voter, financial, and personal records.
For instance, there was alleged unauthorized access to the Continuous Voter Registration (CVR) database of the Independent National Electoral Commission (INEC) during a nationwide CVR exercise.
INEC earlier released the preliminary findings of its investigation into the matter, saying that it found no external breach of its systems and that the personal information of over 90 million registered voters was not compromised.
Despite this, CSOs argued that the incident underscored the lack of oversight, adding that it showed that while data privacy laws are in place, sensitive information can be easily moved from a secure government database and into the hands of private political entities.
The coalition also pointed out regulators’ failure to conduct human rights impact assessments on public surveillance systems before related programs were deployed, urging the government to act on these issues by subjecting public institutions to the same compliance requirements as private organizations.
“This is the asymmetry at the heart of the crisis: citizens are under-protected from data abuse and over-exposed to state monitoring and punishment,” the CSOs stated.

AI-Powered Scams are Biggest Payment Fraud Threat -Visa Report

Visa, a multinational firm into payment card services says Artificial intelligence enabled scams have emerged as the fastest-growing source of consumer payment fraud globally as cybercriminals increasingly target people.

Visa stated this in its Mid-year 2026 Biannual Threats Report released on Wednesday in Lagos.
The report said scammers were increasingly using AI tools and social engineering tactics to manipulate consumers into authorising fraudulent payments themselves.Premier League Fixtures
It indicated that from July to December 2025, Visa identified nearly one billion dollars in scam-related activity, making scams the largest category of consumer payment fraud.
According to the report, fraudsters now impersonate trusted brands and institutions, create a sense of urgency and deceive victims into completing seemingly legitimate transactions.
The report said stronger network-level security had reduced opportunities for direct system compromises, forcing criminals to shift their focus to exploiting human trust.
It revealed that fraud involving device tokens declined by 9.6 per cent between July and December 2025, compared with the same period in 2024.
The report identified accelerating scams, growing use of AI in fraud, migration of attacks from technology to people, and evolving ransomware trends as key developments shaping payment security.
It stated that global ransomware activity rose by 26 per cent during the review period compared with the corresponding period in 2024.
However, only 23 per cent of ransomware victims paid ransoms, the lowest level on record, reflecting improved resilience and recovery capabilities, according to the report.
Commenting, Mr Paul Fabara, chief Risk and Client Services officer, Visa, said that payments at network level continued to get safer, but threats were evolving faster than ever
Fabara said criminals were increasingly using deception, urgency and AI-enabled tools to exploit trust, requiring stronger collaboration across the payments ecosystem.
Also, Andrew Uaboi, vice president and Cluster head, Visa West Africa, said AI had significantly lowered the barriers to entry for fraudsters.
“What once required deep technical skill can now be executed with a prompt,” Uaboi said.
He said intelligence-driven defence and coordinated action across the ecosystem were becoming increasingly critical to protecting consumers from emerging threats.

How to Build a Safer Cyberworld for People, Business, and Society

Kaspersky has released its Sustainability Report for 2024–2025, outlining how the company is working toward a safer and more resilient digital future.

The report reflects Kaspersky’s broader commitment to responsible business — protecting people and organisations from cyberthreats, supporting law enforcement cooperation, investing in secure technologies, and helping strengthen the digital resilience of societies and economies.
In 2024-2025, the company continued advancing digital sustainability and strengthening global cyber resilience, reducing thedisruption, financial losses and social risks caused by cyber incidents, and enabling safer and more stable conditions for digital adoption across economies and societies.
Over the period, the number of detected advanced persistent threat (APT) groups and operations has increased significantly — by 74% compared to 2023, supported by intelligence gathered through five dedicated Expertise Centers.
Building a safer cyberworld
A significant part of Kaspersky’s social impact comes from the company’s cooperation with global law enforcement agencies. During the reporting period, the company contributed to joint operations with INTERPOL and AFRIPOL that resulted in the arrest of more than 2,600 suspected cybercriminals.
From a sustainability perspective, this shrinks the opportunities attackers can exploit — making digital environments safer for governments, businesses and individuals, and lowering the long-term economic and social costs associated with cyber incidents.
During the reporting period, Kaspersky formalised its collaborations with AFRIPOL, signing a five-year cooperation agreement, and delivered cybersecurity training to law enforcement representatives from 23 African countries, covering the fundamentals of Security Operations Center (SOC) operations and advanced threat hunting techniques.
This capacity-building work has a compounding effect: as local teams become more capable of independently detecting and responding to threats, the overall resilience of the digital ecosystem increases, while the cost and duration of cyber incidents decrease over time.
Implementing future tech
To effectively protect people, businesses and public institutions from evolving cyberthreats, Kaspersky constantly improves its security solutions and conducts cybersecurity research to stay one step ahead of attackers.
In 2024–2025 the company was granted 155 patents, including 135 AI-related ones. Its global R&D team of around 3,000 employees also produced 373 research publications. Together, these efforts help advance the baseline of secure technologies available to the market.
This reduces systemic vulnerability in digital infrastructure and supports more stable technological adoption at scale.
Responsible innovation frameworks further reinforce this effect. By joining the European Commission’s AI Pact and supporting the UN Global Digital Compact, Kaspersky has aligned its development practices with emerging global governance standards.
This contributes to sustainability by helping reduce the risks of unsafe AI deployment, such as misuse, bias or system exploitation, which could otherwise undermine trust in digital transformation.
The company’s Cyber Immunity approach, implemented through KasperskyOS, adds another layer of long-term sustainability impact by shifting security from reactive protection to architectural resilience.
Instead of repeatedly patching vulnerabilities, systems are designed to be inherently resistant to compromise, which reduces maintenance overhead, lifecycle risk and resource inefficiency in securing digital environments.
Among the new product launches, the Kaspersky eSIM Store expanded the company’s offering beyond cybersecurity into mobile connectivity. By reducing reliance on physical SIM cards and making global mobile access more seamless, the solution supports more sustainable travel and digital lifestyles.
Together with that, Kaspersky also released Kaspersky Cloud Workload Security for protecting cloud workloads wherever they reside: on servers or virtual machines, or in private, public, or hybrid clouds, etc.
“At Kaspersky, we see cybersecurity not only as a technology issue, but as a social one. Every day, people rely on digital services to work, communicate, study, receive services and manage their lives and they need to be able to do this safely.
“That is why our sustainability agenda starts with our core expertise: protecting people, organisations and critical systems from cyberthreats. But it also goes further — through responsible innovation, transparency, partnerships and support for communities.
“This report shows how our technologies, research and cooperation with partners translate into practical impact: fewer risks, stronger resilience and a safer digital environment for everyone,” said Maria Losyukova, Head of ESG & Sustainability at Kaspersky.
