NetScaler vulnerability exploited, AdaptHealth suffers breach, new Android malware

The Cybersecurity and Infrastructure Security Agency (CISA) warned of a critical vulnerability in NetScaler, identified as CVE-2026-19490, with a CVSS score of 9.3, which has been exploited and affects all NetScaler ADC and Gateway appliances. Citrix has patched this vulnerability as of August 19. AdaptHealth reported a data breach affecting over 4.1 million individuals, compromising personal, health, and insurance information, but not Social Security numbers or financial data. A new strain of Android malware, MantaxOtax, attributed to Indonesian threat actors, combines ransomware and spyware, stealing sensitive information and affecting older Android versions. The Gigabud banking trojan has evolved to evade detection by installing a secondary app that hides the malicious application. CISA acting director Nick Andersen emphasized the need for swift adaptation to cybersecurity threats and highlighted staffing improvements within CISA. Russian e-commerce giant Wildberries experienced disruptions from a DDoS attack affecting payments to sellers, following claims of a cyber operation by Ukraine's military intelligence. McKesson faced a cyberattack exposing sensitive data of 6.4 million individuals, with the ShinyHunters group releasing this data after a failed extortion attempt. IDScan confirmed a data breach affecting 150 million individuals, resulting in the theft of personally identifiable information and government-issued documents.

Beware of fake Indeed interview apps used to install spyware

Scammers are exploiting the Indeed platform to target job seekers by using counterfeit Android "interview" applications. Users in the UK and Brazil reported being instructed by supposed employers to download fraudulent apps like MyInterview, which compromised their devices. These scammers post fake job listings and prompt applicants to install apps that mimic Indeed's login page and establish a VPN connection. The malicious apps, classified as Trojan.Droppers, can install additional untrusted software and gain control over devices, complicating uninstallation efforts. Indeed confirmed that their interview process does not require downloading any separate app and warned job seekers against such scams. Indicators of compromise include specific MD5 hashes and package names associated with the Trojan droppers and dropped malware payloads.

Do you really need antivirus software on your Android phone? – Innovation Village

The landscape of mobile security has shifted away from traditional third-party antivirus software, as modern Android devices are equipped with built-in security features. Key components of this security framework include Google Play Protect, which blocked 27 million malicious apps in 2025; application sandboxing that isolates apps; proactive permissions that enhance user privacy; AI-powered threat detection for sophisticated attacks; and strict sideloading policies to limit risks from off-market malware. Despite these defenses, threats such as social engineering, phishing, malicious push notifications, and unsecured public Wi-Fi remain prevalent, often evading traditional antivirus solutions. However, certain scenarios, such as frequent sideloading, using older devices, connecting to public Wi-Fi, or suspected infections, may warrant the use of third-party antivirus apps for additional protection. Overall, the built-in security features of Android provide a strong defense for most users, with user education being crucial for effective smartphone protection.

Android Spyware Asin Targets Arabic Users via Fake News, PDF and War Map Apps

Arabic-speaking users are the target of a new Android spyware called Asin, identified by ESET in early 2025. The malware is distributed through fraudulent websites that mimic legitimate services, including: - govlens[.]net, registered on May 27, 2025, impersonating a government news source. - pdf-reader[.]help, registered on May 29, 2025, claiming to be a secure PDF editor. - live-war-map[.]com, registered on January 20, 2025, providing updates on military incidents. Two of these domains are promoted via social media accounts on Facebook and Telegram. The spyware combines legitimate functionality with covert capabilities, and its campaigns may target journalists and OSINT researchers in Arabic-speaking regions. Artifacts linked to Asin include an upload to VirusTotal from Türkiye in October 2025, an APK downloaded from c-pdf[.]net in December 2025, and a sample disguised as "Syria Defense Map" detected in January 2026. Users must manually install the applications and grant permissions for the spyware to operate.

Fake ‘Cockroach Janta Party’ Android app flagged as critical malware threat, report warns

A cybersecurity report released on May 22, 2026, identifies a counterfeit Android application posing as the official app of the Cockroach Janta Party as a significant malware threat. The malicious app, known as Cockroach.Janta.Party, functions as a Remote Access Trojan (RAT) and can infiltrate Android devices, steal sensitive information, intercept communications, and control infected smartphones. The genuine Cockroach Janta Party has no affiliation with this app and is a victim of brand impersonation. The app is distributed through WhatsApp, Telegram, and misleading websites, particularly a rogue domain, cockroachjantaparty[.]org. It targets Android devices running versions 8.0 to 14 and requests elevated permissions, including access to camera, SMS, call logs, and contacts, while misusing the Android Accessibility Service to read on-screen content and grant itself additional permissions. The app contains multiple malicious modules for data exfiltration and uses a Command and Control infrastructure based on the Telegram Bot API. Users are advised to uninstall the app, disable Accessibility permissions, reset banking credentials, enable two-factor authentication, and conduct a full mobile security scan. The legitimate Cockroach Janta Party is encouraged to issue a formal clarification regarding the impersonation.

MiningDropper Android Malware Exploits Lumolight App

Researchers at Cyble Research and Intelligence Labs (CRIL) have discovered an Android malware framework called MiningDropper, which is being used in various campaigns to distribute malicious payloads such as cryptocurrency miners, infostealers, Remote Access Trojans (RATs), and banking malware. Over 1,500 MiningDropper samples were detected in one month, with many showing minimal antivirus detection. MiningDropper operates as a multi-stage delivery framework that employs techniques like XOR-based obfuscation and AES encryption to evade detection. A recent variant uses a trojanized version of the Lumolight application as the initial infection vector, often spread through phishing links and fraudulent websites. The malware executes a series of stages, starting with decrypting an embedded asset and loading additional payloads, including a counterfeit Google Play update interface to deceive users. Two main campaign clusters have been identified: an infostealer campaign targeting Indian users by impersonating trusted entities, and a global campaign distributing the BTMOB RAT, which enables credential theft and device takeover. The final payload capabilities include extracting sensitive data, enabling full device compromise, facilitating financial fraud, and unauthorized cryptocurrency mining. MiningDropper's modularity allows it to adapt and scale across various campaigns while maintaining low detection rates.

Using Windows 10? Do This Now to Lower Your Risk of Being Hacked

Support for Windows 10 officially ended last year, and Microsoft recommends users transition to Windows 11 or buy new computers. Users will no longer receive security updates, and any issues encountered will not be supported by Microsoft. Windows Update will indicate that devices are no longer receiving updates, leaving users to manage security vulnerabilities themselves. Microsoft Defender Antivirus will continue to receive updates until October 2028, and users can enroll in Extended Security Updates (ESU) for an additional year of security updates until October 13, 2026, under certain conditions. Windows 11 installations surpassed Windows 10 in June 2025, with Windows 11 at 53.7% and Windows 10 at 42.7%. Users opting to stay on Windows 10 should implement third-party security solutions to mitigate risks from the lack of official updates.

Kimsuky Spreads DocSwap Android Malware via QR Phishing Posing as Delivery App

A new Android malware campaign has been launched by the North Korean threat actor Kimsuky, introducing a variant called DocSwap. This malware is distributed via QR codes on phishing websites that impersonate CJ Logistics. Attackers use QR codes and notification pop-ups to lure victims into downloading the malware, which decrypts an embedded APK and activates Remote Access Trojan (RAT) capabilities. The malicious app is disguised as a legitimate application to bypass Android's security measures. Victims are tricked into installing the app through smishing texts or phishing emails that mimic delivery companies. The app downloads an APK named "SecDelivery.apk," which then loads the malware. It requests permissions to access various device functions and registers a service that simulates an OTP authentication screen. The app connects to an attacker-controlled server, allowing execution of commands such as logging keystrokes, capturing audio, and gathering sensitive information. Additionally, two other malicious samples have been identified, disguised as a P2B Airdrop app and a trojanized version of the BYCOM VPN app. The campaign also includes phishing sites mimicking popular South Korean platforms to capture user credentials.
