Cybersecurity researchers have discovered a nascent Android remote access trojan (RAT) called PlayPraetor that has infected more than 11,000 devices, primarily across Portugal, Spain, France, Morocco, Peru, and Hong Kong. "The botnet's rapid growth, which now exceeds 2,000 new infections per week, is driven by aggressive campaigns focusing on Spanish and French speakers, indicating a strategic shift away from its previous common victim base," Cleafy researchers Simone Mattia, Alessandro Strino, and Federico Valentini said in an analysis of the malware. PlayPraetor, managed by a Chinese command-and-control (C2) panel, doesn't significantly deviate from other Android trojans in that it abuses accessibility services to gain remote control and can serve fake overlay login screens atop nearly 200 banking apps and cryptocurrency wallets in an attempt to hijack victim accounts. PlayPraetor was first documented by CTM360 in March 2025, detailing the operation's u...

Cybersecurity researchers have discovered a new, large-scale mobile malware campaign that's targeting Android and iOS platforms with fake dating, social networking, cloud storage, and car service apps to steal sensitive personal data. The cross-platform threat has been codenamed SarangTrap by Zimperium zLabs. Users in South Korea appear to be the primary focus. "This extensive campaign involved over 250 malicious Android applications and more than 80 malicious domains, all disguised as legitimate dating and social media applications," security researcher Rajat Goyal said . The bogus domains, which impersonate legitimate app store listing pages, are used as a lure to trick users into installing these apps, resulting in the exfiltration of contact lists and images, all while keeping up an illusion of legitimacy. Once installed, the Android apps also prompt the victim to enter an invitation code, after which it's validated against a command-and-control (C2) server. ...

Cybersecurity researchers have unearthed new Android spyware artifacts that are likely affiliated with the Iranian Ministry of Intelligence and Security (MOIS) and have been distributed to targets by masquerading as VPN apps and Starlink, a satellite internet connection service offered by SpaceX. Mobile security vendor Lookout said it discovered four samples of a surveillanceware tool it tracks as DCHSpy one week after the onset of the Israel-Iran conflict last month. Exactly how many people may have installed these apps is not clear. "DCHSpy collects WhatsApp data, accounts, contacts, SMS, files, location, and call logs, and can record audio and take photos," security researchers Alemdar Islamoglu and Justin Albrecht said . First detected in July 2023, DCHSpy is assessed to be the handiwork of MuddyWater , an Iranian nation-state group tied to MOIS. The hacking crew is also called Boggy Serpens, Cobalt Ulster, Earth Vetala, ITG17, Mango Sandstorm (formerly Mercury), Se...

Cybersecurity researchers have discovered a new hacking technique that exploits weaknesses in the eSIM technology used in modern smartphones, exposing users to severe risks. The issues impact the Kigen eUICC card. According to the Irish company's website, more than two billion SIMs in IoT devices have been enabled as of December 2020. The findings come from Security Explorations, a research lab of AG Security Research company. Kigen awarded the company a $30,000 bounty for their report. An eSIM, or embedded SIM, is a digital SIM card that's embedded directly into a device as software installed onto an Embedded Universal Integrated Circuit Card (eUICC) chip. eSIMs allow users to activate a cellular plan from a carrier without the need for a physical SIM card. eUICC software offers the ability to change operator profiles, remote provisioning, and management of SIM profiles. "The eUICC card makes it possible to install the so-called eSIM profiles into the target chi...

Cybersecurity researchers have discovered an Android banking malware campaign that has leveraged a trojan named Anatsa to target users in North America using malicious apps published on Google's official app marketplace. The malware, disguised as a "PDF Update" to a document viewer app, has been caught serving a deceptive overlay when users attempt to access their banking application, claiming the service has been temporarily suspended as part of scheduled maintenance. "This marks at least the third instance of Anatsa focusing its operations on mobile banking customers in the United States and Canada," Dutch mobile security company ThreatFabric said in a report shared with The Hacker News. "As with previous campaigns, Anatsa is being distributed via the official Google Play Store." Anatsa, also referred to as TeaBot and Toddler, has been known to be active since at least 2020, typically delivered to victims via dropper apps. Early last year, An...

Google has been ordered by a court in the U.S. state of California to pay $314 million over charges that it misused Android device users' cellular data when they were idle to passively send information to the company. The verdict marks an end to a legal class-action complaint that was originally filed in August 2019. In their lawsuit, the plaintiffs argued that Google's Android operating system leverages users' cellular data to transmit a "variety of information to Google" without their permission, even when their devices are kept in an idle state. "Although Google could make it so that these transfers happen only when the phones are connected to Wi-Fi, Google instead designed these transfers so they can also take place over a cellular network," they said. "Google's unauthorized use of their cellular data violates California law and requires Google to compensate Plaintiffs for the value of the cellular data that Google uses for its own be...

A mobile ad fraud operation dubbed IconAds that consisted of 352 Android apps has been disrupted, according to a new report from HUMAN. The identified apps were designed to load out-of-context ads on a user's screen and hide their icons from the device home screen launcher, making it harder for victims to remove them, per the company's Satori Threat Intelligence and Research Team. The apps have since been removed from the Play Store by Google. The ad fraud scheme accounted for 1.2 billion bid requests a day, at the height of its activity. The vast majority of IconAds-associated traffic originated from Brazil, Mexico, and the United States. It's worth noting that IconAds is a variant of a threat that's also tracked by other cybersecurity vendors under the names HiddenAds and Vapor , with the malicious apps repeatedly slipping past the Google Play Store since at least 2019 . Some of the common characteristics of these apps include the use of obfuscation to conceal...

Microsoft has said that it's ending support for passwords in its Authenticator app starting August 1, 2025. Microsoft's move is part of a much larger shift away from traditional password-based logins. The company said the changes are also meant to streamline autofill within its two-factor authentication (2FA) app, making the experience simpler and more secure. Over the past few years, Microsoft has been pushing for a passwordless future using technologies like passkeys , Windows Hello, and FIDO2-based authentication. These methods offer better protection against phishing and password reuse, which are still major attack vectors. While it may feel like a hassle at first, this change is actually aimed at reducing your risk in the long run. "Starting July 2025, the autofill feature in Authenticator will stop working, and from August 2025, passwords will no longer be accessible in Authenticator," Microsoft said in a support document for Authenticator. It's worth noti...

The U.S. House of Representatives has formally banned congressional staff members from using WhatsApp on government-issued devices, citing security concerns. The development was first reported by Axios. The decision, according to the House Chief Administrative Officer (CAO), was motivated by worries about the app's security. "The Office of Cybersecurity has deemed WhatsApp a high-risk to users due to the lack of transparency in how it protects user data, absence of stored data encryption, and potential security risks involved with its use," the CAO said in a memo, according to Axios. To that end, House staff are prohibited from downloading the app on any device issued by the government, including its mobile, desktop, or web browser versions. WhatsApp has pushed back against these concerns, stating messages sent on the platform are end-to-end encrypted by default, and that it offers a "higher level" of security than most of the apps on CAO's approved ...

Meta Platforms on Wednesday announced that it's adding support for passkeys, the next-generation password standard, on Facebook. "Passkeys are a new way to verify your identity and login to your account that's easier and more secure than traditional passwords," the tech giant said in a post. Support for passkeys is expected to be available "soon" on Android and iOS mobile devices. The feature is also coming to its Messenger platform in the coming months. The company said passkeys can also be used to auto-fill payment information when making purchases using Meta Pay. Meta previously rolled out passkeys support for WhatsApp on Android in October 2023, and on iOS a few months later in April 2024. There is no word yet on when it plans to bring passkeys to Instagram. Passkeys, backed by the FIDO Alliance, is a passwordless authentication solution that allows users to securely sign in to online services by using biometrics or the device lock PIN code. ...

A growing number of malicious campaigns have leveraged a recently discovered Android banking trojan called Crocodilus to target users in Europe and South America. The malware, according to a new report published by ThreatFabric, has also adopted improved obfuscation techniques to hinder analysis and detection, and includes the ability to create new contacts in the victim's contacts list. "Recent activity reveals multiple campaigns now targeting European countries while continuing Turkish campaigns and expanding globally to South America," the Dutch security company said . Crocodilus was first publicly documented in March 2025 as targeting Android device users in Spain and Turkey by masquerading as legitimate apps like Google Chrome. The malware comes fitted with capabilities to launch overlay attacks against a list of financial apps retrieved from an external server to harvest credentials. It also abuses accessibility services permissions to capture seed phrases as...

Three security vulnerabilities have been disclosed in preloaded Android applications on smartphones from Ulefone and Krüger&Matz that could enable any app installed on the device to perform a factory reset and encrypt an application. A brief description of the three flaws is as follows - CVE-2024-13915 (CVSS score: 6.9) - A pre-installed "com.pri.factorytest" application on Ulefone and Krüger&Matz smartphones exposes a "com.pri.factorytest.emmc.FactoryResetService" service that allows any installed application to perform a factory reset of the device. CVE-2024-13916 (CVSS score: 6.9) - A pre-installed "com.pri.applock" application on Kruger&Matz smartphones allows a user to encrypt any application using user-provided PIN code or by using biometric data. The app also exposes a "com.android.providers.settings.fingerprint.PriFpShareProvider" content provider's "query()" method that permits any malicious app already ...

Qualcomm has shipped security updates to address three zero-day vulnerabilities that it said have been exploited in limited, targeted attacks in the wild. The flaws in question, which were responsibly disclosed to the company by the Google Android Security team, are listed below - CVE-2025-21479 and CVE-2025-21480 (CVSS score: 8.6) - Two incorrect authorization vulnerabilities in the Graphics component that could result in memory corruption due to unauthorized command execution in GPU microcode while executing a specific sequence of commands CVE-2025-27038 (CVSS score: 7.5) - A use-after-free vulnerability in the Graphics component that could result in memory corruption while rendering graphics using Adreno GPU drivers in Chrome "There are indications from Google Threat Analysis Group that CVE-2025-21479, CVE-2025-21480, CVE-2025-27038 may be under limited, targeted exploitation," Qualcomm said in an advisory. "Patches for the issues affecting the Adreno Grap...

A new malware campaign is distributing a novel Rust-based information stealer dubbed EDDIESTEALER using the popular ClickFix social engineering tactic initiated via fake CAPTCHA verification pages. "This campaign leverages deceptive CAPTCHA verification pages that trick users into executing a malicious PowerShell script, which ultimately deploys the infostealer, harvesting sensitive data such as credentials, browser information, and cryptocurrency wallet details," Elastic Security Labs researcher Jia Yu Chan said in an analysis. The attack chains begin with threat actors compromising legitimate websites with malicious JavaScript payloads that serve bogus CAPTCHA check pages, which prompt site visitors to "prove you are not [a] robot" by following a three-step process, a prevalent tactic called ClickFix . This involves instructing the potential victim to open the Windows Run dialog prompt, paste an already copied command into the "verification window"...

Apple on Tuesday revealed that it prevented over $9 billion in fraudulent transactions in the last five years, including more than $2 billion in 2024 alone. The company said the App Store is confronted by a wide range of threats that seek to defraud users in various ways, ranging from "deceptive apps designed to steal personal information to fraudulent payment schemes that attempt to exploit users." The tech giant said it terminated more than 46,000 developer accounts over fraud concerns and rejected an additional 139,000 developer enrollment as part of efforts to prevent bad actors from submitting their apps to the App Store. Furthermore, the company said it rejected over 711 million customer account creations and deactivated nearly 129 million customer accounts last year with an aim to block these accounts from conducting nefarious activity, such as spamming or manipulating ratings and reviews, charts, and search results that could compromise the integrity of the App S...

Threat hunters have exposed a novel campaign that makes use of search engine optimization (SEO) poisoning techniques to target employee mobile devices and facilitate payroll fraud. The activity, first detected by ReliaQuest in May 2025 targeting an unnamed customer in the manufacturing sector, is characterized by the use of fake login pages to access the employee payroll portal and redirect paychecks into accounts under the threat actor's control. "The attacker's infrastructure used compromised home office routers and mobile networks to mask their traffic, dodging detection and slipping past traditional security measures," the cybersecurity company said in an analysis published last week. "The adversary specifically targeted employee mobile devices with a fake website impersonating the organization's login page. Armed with stolen credentials, the adversary gained access to the organization's payroll portal, changed direct deposit information, and re...

Cybersecurity researchers have discovered a new campaign that employs malicious JavaScript injections to redirect site visitors on mobile devices to a Chinese adult-content Progressive Web App (PWA) scam. "While the payload itself is nothing new (yet another adult gambling scam), the delivery method stands out," c/side researcher Himanshu Anand said in a Tuesday analysis. "The malicious landing page is a full-blown Progressive Web App ( PWA ), likely aiming to retain users longer and bypass basic browser protections." The campaign is designed to explicitly filter out desktop users, primarily focusing on mobile users. The activity has been described as a client-side attack that uses third-party JavaScript and only triggers on mobile devices. The use of PWAs, a type of application built using web technologies that provide a user experience similar to that of a native app built for a specific platform like Windows, Linux, macOS, Android, or iOS, is seen as an at...

Google on Thursday announced it's rolling out new artificial intelligence (AI)-powered countermeasures to combat scams across Chrome, Search, and Android. The tech giant said it will begin using Gemini Nano , its on-device large language model (LLM), to improve Safe Browsing in Chrome 137 on desktops. "The on-device approach provides instant insight on risky websites and allows us to offer protection, even against scams that haven't been seen before. Gemini Nano's LLM is perfect for this use because of its ability to distill the varied, complex nature of websites, helping us adapt to new scam tactics more quickly," the company said . Google noted that it's already using this AI-driven approach to tackle remote tech support scams, which often seek to trick users into parting with their personal or financial information under the pretext of a non-existent computer problem. This works by evaluating the web pages using the LLM for potential signals that are...
