New Malware Targets Crypto Users with Fake Ads, Steals Keys

A new strain of malware is targeting cryptocurrency enthusiasts through deceptive online advertisements that mimic legitimate promotions for crypto wallets and trading platforms. This malware, described as a multi-stage infostealer, begins with an ad redirect that prompts users to download a fake update or extension. Once installed, it monitors clipboard activity to copy and alter cryptocurrency addresses, redirecting funds to attackers' wallets. The malware can evade detection by many antivirus solutions and is often hosted on platforms like GitHub disguised as open-source tools. Victims may not realize they have been compromised until their funds are stolen. Experts recommend using ad blockers, verifying URLs, utilizing hardware wallets, keeping software updated, and employing multi-factor authentication as protective measures. Regular system scans with advanced tools like Malwarebytes and training for employees on malvertising risks are also advised for enterprises.

ANDROID MALWARE POSING AS INDIAN BANK APPS

The report discusses a sophisticated Android malware targeting users in India, which disguises itself as legitimate banking applications to steal credentials and conduct unauthorized financial activities. The malware employs advanced techniques such as silent installation, exploitation of Android permissions, and remote command execution to avoid detection. It utilizes Firebase for command-and-control operations and phishing pages that mimic real banking interfaces. The malware consists of a modular architecture with a dropper and a main payload. The dropper requests several Android permissions, including ACCESSNETWORKSTATE, REQUESTINSTALLPACKAGES, and QUERYALLPACKAGES, which facilitate reconnaissance and persistence. The dropper uses a silent installation mechanism to load additional payloads without user awareness. The main payload requests permissions that enable data theft and stealthy operation, such as READSMS, SENDSMS, and RECEIVEBOOTCOMPLETED. It hides itself from the user's app list and employs separate classes for specific malicious tasks, including harvesting user credentials and collecting debit card information. The phishing page mimics a legitimate banking app to capture user data effectively. The malware also monitors incoming SMS messages, extracts critical metadata, and can silently forward calls to an attacker-controlled number. A specific APK sample impersonating an Indian banking application was observed on April 3, 2025, highlighting ongoing trends in mobile-based credential theft and financial fraud. Recommendations include enforcing stricter mobile application security standards, launching public awareness campaigns, implementing threat intelligence-driven filtering, and deploying mobile endpoint detection solutions.

Fake Indian Banking Apps on Android Steal Login Credentials from Users

A recently discovered malicious Android application poses significant risks by masquerading as legitimate banking apps in India. It facilitates credential theft, conducts surveillance, and executes unauthorized financial transactions. The malware operates on a modular architecture with a dropper and primary payload, employing deceptive user interfaces and silent installation techniques to evade detection. The dropper requests extensive permissions, including ACCESSNETWORKSTATE, REQUESTINSTALLPACKAGES, and QUERYALLPACKAGES, to monitor connectivity, install secondary APKs without user awareness, and profile installed apps. It loads a hidden payload and initiates installation using an INSTALL_NOW flag, bypassing app store scrutiny. The main payload requests additional permissions such as READSMS, SENDSMS, and RECEIVESMS for intercepting one-time passwords (OTPs) and two-factor authentication (2FA) codes. It also requests REQUESTIGNOREBATTERYOPTIMIZATIONS, READPHONESTATE, and READPHONENUMBERS for uninterrupted execution, device fingerprinting, and potential call forwarding abuse. Data exfiltration occurs through Firebase Realtime Database, storing user IDs and intercepted SMS metadata. The malware uses Firebase for command-and-control operations and generates phishing pages resembling authentic banking interfaces. Delivery methods include smishing, email phishing, WhatsApp bots, vishing calls, SEO-poisoned websites, malvertising, Trojanized utilities, QR/NFC attacks, preloaded malware on counterfeit devices, and exploitation of accessibility service vulnerabilities. Indicators of compromise include specific SHA256 hashes for the base payload and main payload.

Microsoft Windows Warning—Do Not Install This Critical Update

A significant alert has been issued regarding a new browser update threat targeting Microsoft Windows users, as reported by Palo Alto Networks’ Unit 42. Attackers are injecting malicious JavaScript into legitimate websites, misleading users into believing they need to update their browsers. These deceptive messages often use realistic branding and create urgency, prompting users to download and execute scripts that enable malware to retrieve the NetSupport RAT code. This malware allows for remote device control, data exfiltration, and modification of the Windows Registry, complicating its removal. On February 18, 2025, the NetSupport RAT delivered StealC, a credential-stealing malware designed to capture sensitive login information. The SmartApeSG campaign highlights the risks of social engineering and fileless attack techniques, exploiting trusted software update mechanisms. Recommended mitigation strategies include blocking domains linked to SmartApeSG, deploying signatures to detect malicious JavaScript, monitoring anomalous process relationships, restricting PowerShell execution policies, and educating employees about fake update prompts. Users are advised to follow conventional methods for browser updates, check for updates through their browsers, and ensure automatic updates are enabled.

SilentSelfie Exploited 25 Websites To Deploy Malicious Android Application

Researchers uncovered a cyber espionage campaign called “SilentSelfie” targeting Kurdish communities, exploiting 25 compromised websites with four variants of malicious JavaScript. The campaign, active since late 2022, utilized watering hole attacks and a covert Android application disguised as a news app to collect sensitive data, including location and contacts. The attackers employed obfuscation techniques and used compromised web servers for communication. A total of 21 Kurdish websites were affected, primarily linked to “Rojava” and Kurdish political entities. The campaign remained undetected for over 18 months, with potential links to Turkish intelligence, Syrian government agencies, and the Kurdistan Regional Government of Iraq. Compromised sites included ‘RojNews’ and ‘YPG Rojava.’
