Fileless Malware and Email Authentication Gaps

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.

Australia probes Roblox and Minecraft over child safety

Australia's eSafety regulator has issued legally enforceable transparency notices to gaming companies, including Microsoft and Roblox, requiring them to detail their measures against sexual exploitation and radicalisation. The eSafety Commissioner, Julie Inman Grant, highlighted that 90% of Australians aged eight to seventeen engage in online gaming, which poses risks such as grooming and radicalisation. Non-compliance with the notices could lead to penalties. Microsoft is reviewing the notice, while Roblox is facing over 140 lawsuits in U.S. federal courts for allegedly facilitating child sexual exploitation. Roblox has reached settlements in Alabama and West Virginia and plans to introduce tailored accounts for younger users.

Quarter Muncher: My love-hate relationship with Minecraft

Minecraft, developed by Mojang Studios, was released in May 2009 and has become one of the best-selling games of all time. It features two primary modes: survival and creative. The game has undergone nearly 16 years of updates while maintaining its core simplicity. The author reflects on their personal journey with Minecraft, starting from childhood and shifting interests over the years, including a period of decreased engagement due to the popularity of Fortnite in 2017. They experienced a resurgence of interest in late 2022 and early 2023 through survival mode but found playing alone less enjoyable. In late 2024, they attempted to create a new realm with friends, which lasted about a month. Despite their ongoing passion for Minecraft, the author struggles with the lack of enthusiasm from friends, leading to short-lived gaming experiences.

Best Free Antivirus 2026: Keep Your Devices Safe With These Free Tools

Many free antivirus services monetize user attention or data, and caution is advised when selecting these options. Recommended free antivirus tools should be free of ads or spyware. Trustworthy antivirus providers present clear privacy policies detailing data collection and sharing practices. Effective free antivirus tools offer real-time protection, on-demand malware scans, and user-friendly features. While free antivirus software is generally sufficient, paid options provide additional cybersecurity tools. The best free antivirus tools consume less than 5% of system resources, with active scans ideally not exceeding 40% CPU usage. Avast faced backlash for selling customer data to over 100 third parties and was fined million by the FTC in 2024. Kaspersky was banned in the U.S. in 2024 due to concerns about potential intelligence exploitation, and it cannot be recommended at this time.

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.
