New Rokarolla Android Trojan Targets 217 Banking and Crypto Apps

Zimperium’s zLabs researchers have analyzed a newly identified Android banking trojan named Rokarolla, which targets 217 distinct banking and cryptocurrency applications. It is distributed through malicious websites that impersonate popular platforms like TikTok and Google Chrome, with one identified distribution point being hxxps://infocontablidades[.]it[.]com/. The malware uses a dropper disguised as Google Play Protect to install a second-stage payload and gain Accessibility Services access, allowing it to simulate user interactions and manipulate on-screen elements. Rokarolla downloads counterfeit HTML login pages for targeted applications and overlays them to capture user credentials, including sensitive card information. It can also deploy a fraudulent PIN entry screen, read and send SMS messages, intercept one-time codes from banks, and block incoming calls. The malware rewrites the clipboard, operates a keylogger and screen content logger, and scrapes WhatsApp contact data. It captures screenshots without alerting users and has a resilient command-and-control infrastructure with multiple fallback domains. No product flaws are exploited, and defenses against it include installing apps only from Google Play and being cautious with Accessibility Services. Zimperium’s Mobile Threat Defense and zDefend products can detect Rokarolla, and a list of indicators of compromise is available on their GitHub repository.

Automate Amazon Aurora PostgreSQL major or minor version upgrade using AWS Systems Manager and Amazon EC2

Managing upgrades for the Aurora PostgreSQL-Compatible Edition can be labor-intensive and error-prone when done manually. Automating Amazon Aurora PostgreSQL upgrades can reduce manual effort by up to 80% and minimize downtime risks through consistent procedures. The automation solution uses AWS Systems Manager, Amazon EC2, and AWS Secrets Manager, structured around two modules: PREUPGRADE for readiness checks and UPGRADE for the actual upgrade process. The solution identifies upgrade candidates using database tags, creates safety backups with Copy-on-Write clones, manages the upgrade process with minimal human intervention, and offers real-time monitoring and email notifications. The workflow includes logging into the Systems Manager console, downloading the upgrade script, identifying Aurora PostgreSQL clusters based on tags, retrieving credentials from AWS Secrets Manager, executing pre-upgrade checks or upgrades, uploading log files to Amazon S3, and sending email notifications via Amazon SNS. Prerequisites include familiarity with the Aurora upgrade process, appropriate IAM permissions, creating a maintenance user, setting up AWS Secrets Manager, tagging Aurora clusters, creating an S3 bucket, and configuring an SNS topic for notifications. Implementation steps involve reviewing setup instructions, uploading the upgrade script to S3, creating an AWS Systems Manager automation document, executing the automation document, and monitoring the upgrade process through logs generated during pre-upgrade and upgrade phases. The logs provide detailed information on tasks performed, including replication slot status and configuration backups. After testing, it is recommended to clean up resources to avoid future charges.

Fake verification pages are stealing Steam accounts from players

Online gamers are being warned about a scam targeting Steam accounts through counterfeit FACEIT verification pages that look authentic. These fraudulent sites feature official branding and functional links, tricking users into entering their passwords. The scam is particularly aimed at FACEIT players, as it exploits the connection between FACEIT and Steam, where players link their accounts. The scam starts with a website mimicking an official FACEIT page, claiming to offer free identity verification. Scammers use lookalike URLs, such as faceit-discord.com and faceit-clubs-verify.com, to deceive users. The site may display subtle errors, like conflicting copyright dates, and encourages users to click a “Sign in through Steam” button, which leads to a fake login window designed to steal user credentials. To protect against this scam, users should verify the website address, be cautious of blurry QR codes, treat urgent messages as suspicious, navigate directly to official sites, and consider using tools like Malwarebytes Browser Guard. If users have already entered their details, they should change their Steam password, enable Steam Guard, and check for unauthorized activity. The scam's effectiveness lies in its convincing presentation and the use of Browser-in-the-Browser attacks, which manipulate the perceived address bar.

How We Test Antivirus and Security Software

Most software applications clearly indicate their functionality, but the effectiveness of antivirus utilities is often less tangible. PCMag rigorously evaluates antivirus products through comprehensive tests that validate their claims, including real-world malware samples and various protective measures. Each antivirus tool is assessed based on its on-demand scanner and real-time monitor capabilities. PCMag compiles fresh malware samples annually, analyzing them to ensure they are suitable for testing. The testing process includes evaluating malware-blocking capabilities and web-level protection against known malware-hosting sites. Phishing site detection is also tested using recent URLs, and antispam testing has been simplified due to the effectiveness of email providers. Performance impact tests have been discontinued as modern security suites show improved efficiency. Firewall protection is evaluated through program control, exploit defenses, and overall resilience against malware. Parental control features are tested for effectiveness in content filtering and monitoring. Ransomware protection is assessed by releasing real-world samples in a controlled environment. PCMag monitors independent antivirus lab tests from various organizations, including AV-Test, AV-Comparatives, SE Labs, MRG-Effitas, and AVLab, to inform their reviews. An aggregate testing score is calculated to summarize lab results. Testing methodologies do not include VPN evaluations, which are covered separately.

10,000 Users Exposed As Fake Document Reader App Delivers Anatsa Banking Trojan

Security researchers from ThreatLabz discovered a malicious document reader app on the Google Play Store that delivered the Anatsa Android banking trojan. The app, which had over 10,000 downloads before its removal, disguised itself as a legitimate file management tool using the package name com.groundstation.informationcontrol.filestationbrowsefilesreaddocs. It employed a "dropper" technique to hide its malicious code, connecting to an external server to retrieve the malware payload after installation. Anatsa is designed to steal financial information by overlaying a fake login screen over legitimate banking apps, capturing user credentials and enabling unauthorized transactions. Users are advised to delete the app and monitor their financial accounts. Technical indicators for identifying infections include the Anatsa Installer SHA256 (5c9b09819b196970a867b1d459f9053da38a6a2721f21264324e0a8ffef01e20), Payload URL (http://23.251.108[.]10:8080/privacy.txt), Payload SHA256 Hash (88fd72ac0cdab37c74ce14901c5daf214bd54f64e0e68093526a0076df4e042f), and Command and Control servers (http://172.86.91[.]94/api/ and http://193.24.123[.]18:85/api/).

New RecruitRat, SaferRat, Astrinox, Massiv Android Malware Found Targeting 800 Apps

Cybersecurity researchers from Zimperium zLabs have identified four families of Android malware—RecruitRat, SaferRat, Astrinox, and Massiv—targeting banking and cryptocurrency applications. These malware families can extract sensitive information from over 800 applications. They primarily use phishing and smishing to lure users into downloading malicious software. Phishing involves creating fake websites resembling legitimate login pages, while smishing uses urgent text messages with links to download harmful payloads. RecruitRat targets job seekers with fake employment websites, and SaferRat promises free access to premium video services. Astrinox mimics a business tool and has been linked to a fraudulent Apple App Store page, while Massiv's distribution methods remain unclear. Once installed, these malware applications initiate Overlay attacks, displaying counterfeit screens to capture user credentials. They also use a "blindfold" technique to obscure their activities by overlaying static images on the user's screen. The malware can intercept security codes, capture one-time passwords, and employ keylogging techniques. RecruitRat has a library of over 700 counterfeit login pages that activate with targeted apps. Researchers recommend avoiding links in urgent messages and downloading apps only from official sources.
