Fileless Malware and Email Authentication Gaps

Fileless malware operates stealthily within networks, utilizing legitimate system tools like PowerShell and Windows Management Instrumentation (WMI) to execute malicious code in memory without leaving traces on disk. Traditional antivirus solutions struggle to detect these threats due to their reliance on file signatures. The primary vector for fileless malware is email, where attackers use spoofed messages to trick users into activating malicious scripts. Misconfigurations in Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) records create vulnerabilities that attackers exploit to deliver spoofed emails. Traditional endpoint protection mechanisms are inadequate against fileless attacks, necessitating a shift towards behavioral analysis for detection. Organizations must assess their preparedness by ensuring proper email authentication configurations and enhancing endpoint security capabilities. Integration among security teams and updated employee security awareness programs are also essential. Sendmarc helps organizations mitigate vulnerabilities by providing visibility into SPF, DKIM, and DMARC configurations and enforcing DMARC to block unauthenticated messages.

Another spyware maker caught distributing fake Android snooping apps

The Italian digital rights organization Osservatorio Nessuno has revealed a new malware called Morpheus, used by government agencies for surveillance. Morpheus is disguised as a phone updating application and can extract various data from targets' devices. The spyware is linked to IPS, an Italian firm specializing in lawful interception technologies, which claims to operate in over 20 countries. Morpheus is categorized as "low cost" due to its straightforward infection method, which involves tricking targets into installing the software. Authorities collaborated with the target's mobile service provider to obstruct data and send an SMS prompting the installation of the malware. Once installed, Morpheus exploits Android's accessibility features to access extensive information and masquerades as the WhatsApp application to solicit biometric data. The spyware's code contains Italian phrases and references to "Gomorra," indicating its connection to the Italian spyware industry. The attack is likely linked to political activism in Italy. IPS is among several Italian spyware manufacturers that have emerged following the decline of Hacking Team.

Take Control: Customer-Managed Keys for Lakebase Postgres

Encryption at rest is essential for cloud environments, especially in regulated sectors. Lakebase offers Customer Managed Keys (CMK), allowing organizations to control their encryption keys from preferred Key Management Services (KMS) like AWS KMS, Azure Key Vault, or Google Cloud KMS. Lakebase CMK manages both persistent storage and ephemeral compute, ensuring data security. Lakebase's architecture separates storage and compute layers, enabling elastic scaling and serverless operations. The storage layer maintains persistent data, while the compute layer consists of dynamic Postgres instances. This separation poses encryption challenges, addressed by Lakebase CMK through a hierarchical Envelope Encryption model. The key hierarchy includes: 1. Customer Managed Key (CMK): The Root of Trust in the cloud KMS, never accessed in plaintext by Databricks. 2. Key Encryption Key (KEK): A transient key for wrapping data keys. 3. Data Encryption Keys (DEKs): Unique keys for each data segment, stored in an encrypted state. When data access is needed, Lakebase retrieves DEKs by unwrapping keys from the KMS. If a key is revoked, access to the data is denied, and ephemeral compute instances are terminated. In practice, CMK applies to: 1. Persistence Layer (Storage): All data segments are encrypted with keys controlled by the CMK. 2. Ephemeral Layer (Compute): Each compute instance generates a unique ephemeral key, and upon revocation, the instance is terminated, destroying in-memory keys. CMK implementation follows a delegation model, allowing Security Admins to manage keys without accessing data. The process includes key configuration, workspace binding, and lifecycle management. Key rotation is seamless, requiring no data re-encryption. All cryptographic operations involving the CMK are logged by the cloud provider's audit service. Lakebase CMK is available for Enterprise tier customers, allowing organizations to manage their encryption keys effectively.

Engineering secure passkey sync in Microsoft Password Manager

Passkeys are a new form of authentication that replace traditional passwords, providing a phishing-resistant and streamlined sign-in process. Microsoft Password Manager allows users to save and synchronize passkeys across devices linked to their Microsoft accounts, enhancing accessibility. The architecture for passkey syncing includes confidential computing for sensitive operations, hardware-rooted key protection for encryption keys, tamper-evident recovery storage, and encrypted synchronization across devices. Sensitive passkey operations are executed in Azure's confidential computing environments, ensuring cryptographic materials are processed securely. The encryption keys are protected using Azure Managed HSM, with access governed by attestation-based mechanisms. Registration and recovery processes require user authentication and enforce security measures within confidential computing boundaries, including a lockout state after consecutive incorrect PIN attempts. The system aims to provide a secure and user-friendly experience as part of a transition to a passwordless future.

Trojanized Android App Fuels New Wave of NFC Fraud

A new variant of the NGate malware family has emerged, using a trojanized Android application to capture payment card data and personal identification numbers (PINs). This modified version of HandyPay, a legitimate NFC relay app, has been distributed since November 2025, primarily targeting users in Brazil. The malware intercepts NFC payment card data and allows fraudulent transactions. Two distinct malware samples have been observed, delivered through phishing infrastructure that impersonates a Brazilian lottery site and a Google Play listing for a card protection tool. The trojanized app captures NFC data, requests the victim's card PIN, and transmits this information to attacker-controlled infrastructure. It requires minimal permissions, leveraging its role as the default payment application to evade detection. Evidence suggests that generative AI tools may have been used in its development, indicated by emoji markers in debug logs. ESET has reported its findings to Google, and Google Play Protect can detect known versions of the malware. The developer of HandyPay is investigating the misuse of its application.

NGate Android malware uses HandyPay NFC app to steal card data

A new variant of the NGate malware targets Android users by disguising itself within a trojanized version of the HandyPay app, which is a legitimate mobile payment processing application. This malware, documented since mid-2024, siphons payment card information through the mobile device's near-field communication (NFC) chip and sends the stolen data directly to attackers, who create virtual cards for unauthorized purchases or cash withdrawals from NFC-enabled ATMs. The new variant has been injected with malicious code into the HandyPay app, which has been available on Google Play since 2021. The code includes emojis, indicating the possible use of a generative AI tool in its development. The shift from previous iterations, which used an open-source tool named NFCGate, to HandyPay is likely motivated by financial considerations and the need for evasion, as HandyPay is more affordable and requires fewer permissions. This NGate variant has been active since November 2025, primarily targeting Android devices in Brazil. It employs two main distribution methods: a counterfeit app named “Proteção Cartão” hosted on a fraudulent Google Play page and a fake lottery website that redirects users to WhatsApp to download the malicious APK. Upon installation, the app prompts users to set it as their default NFC payment application, requests their card PIN, and instructs them to tap their card on the phone for reading, transmitting all collected information to an attacker's email address. To protect against such threats, Android users are advised to avoid downloading APKs from outside Google Play, disable NFC when not in use, and use Play Protect to scan for threats.
