How to use screen mirroring on Roku with your Android phone

Owning a Roku TV or streaming box allows for seamless integration with existing tech setups, enhancing the viewing experience. Users can mirror their Android phone's screen to the Roku device, provided both support the Miracast protocol. Most Roku devices support screen mirroring, but some Android devices, like Google Pixels, do not support Miracast natively. Users can still cast individual apps such as YouTube or Netflix using the DIAL protocol. To mirror the screen, users must navigate to the settings menu on the Roku and select the screen mirroring mode. Samsung Galaxy users can easily mirror their screens by using the Smart View feature. While mirroring, a Smart View pill allows users to adjust settings and aspect ratios. If audio issues arise, users should check the volume on both devices. Samsung Galaxy smartphone users can utilize the DeX feature for a desktop-like experience when connected to a Roku. To activate DeX wirelessly, users can access quick settings and select the Wireless DeX toggle. Some lag may occur during wireless use, which can be mitigated by adjusting the TV's picture mode to gaming.

Microsoft will make it harder to illegally activate Windows and close a popular piracy loophole

Microsoft is requiring the use of TPM 2.0 security modules for Key Management Service (KMS) activation servers to combat unlicensed software and corporate piracy. KMS, used by organizations for mass activation of devices, has been targeted by hackers who create counterfeit servers. The new protocol mandates that KMS hosts validate their hardware credentials through the TPM 2.0 chip before activating client devices. This initiative will mainly affect illegal infrastructures in the corporate sector, while legitimate PC users will not be impacted. Starting in August 2026, Windows Server 2025 will introduce hardware readiness alerts to help system administrators prepare for these changes. TPM 2.0 has been required for Windows 11 since 2021, and its application is being expanded to address vulnerabilities in volume licensing.

ClamAV Setup: Linux Antivirus in 12 Steps [2026]

Malware can threaten Linux systems, which are often mistakenly believed to be immune to viruses. It can be introduced through email attachments, infected files, or compromised plugins, especially when Linux servers interact with Windows clients or handle internet uploads. ClamAV is an open-source antivirus engine maintained by Cisco Talos, designed for scanning mail traffic and file uploads. As of mid-2026, the stable release is ClamAV 1.5.x, with version 1.5.2 being the latest patch. To deploy ClamAV, users need root or sudo access on a compatible Linux machine, at least 2 vCPUs and 2GB of RAM, 5GB of free disk space, and outbound HTTPS access to ClamAV’s signature mirrors. The installation process involves several steps, including configuring freshclam for automatic updates, validating detection with the EICAR test file, and setting up cron jobs for regular scans. ClamAV can also be integrated with mail servers and a SIEM for enhanced security. Common pitfalls in deployment include skipping the initial freshclam run and using clamscan instead of clamdscan for repeated scans. ClamAV is free for commercial use and can also scan Windows systems, although it does not replace comprehensive endpoint protection solutions.

How Valve’s desperation to escape Windows 8 turned it into a Linux powerhouse

In 2012, Valve's CEO Gabe Newell expressed concerns about Microsoft's control over the PC market due to Windows 8, prompting the company to explore Linux and develop SteamOS. Valve addressed the "chicken and egg" issue of game compatibility on Linux by introducing Proton, a compatibility layer that allows Windows games to run on Linux without separate versions. The company also began contributing to the Linux ecosystem by upstreaming improvements in graphical rendering and developing the RADV open-source Vulkan driver for AMD GPUs. Valve has made SteamOS available for free download and installation on personal computers, aiming to compete with Windows in the gaming sector and promote broader Linux adoption. As a result, Valve has become a significant player in the Linux landscape, enhancing the gaming experience and benefiting the open-source community.

Scrappy RAT Malware Targets Chrome And Edge Users

A new remote access trojan (RAT) named msaRAT has been identified by Cisco Talos, linked to the Chaos ransomware group and built using Rust. It exploits Chrome and Edge browsers to disguise its traffic and evade detection. MsaRAT operates through a headless browser process, enabling remote code execution and facilitating ransomware deployment, data theft, and other malicious activities. It is typically installed via phishing emails or malicious files, making it resistant to standard browser patches. Cisco Talos recommends specific SNORT rules and a ClamAV signature for detection. Indicators of Compromise (IoC) include traffic to the IP address 172.86.126.18 and the domain is-01-ast.ols-img-12.workers.dev. The malware primarily targets large organizations, but individual users may also be at risk.

Cockroaches using apps that send messages without internet? Here is tech behind it

Delhi police are investigating the methods used by protesters in Central Delhi, particularly those associated with the Cockroach Janta Party (CJP), who are using specialized offline messaging applications to communicate despite internet restrictions and mobile network shutdowns. These apps utilize Bluetooth technology to create local networks, allowing communication without 4G, 5G, or Wi-Fi. One example is Bitchat, an app that enables message exchange via Bluetooth without the need for accounts or central servers. The messages are relayed between devices to form a mesh network, which is effective during internet shutdowns. The police are reaching out to app service providers for user information and are employing various investigative methods, including analyzing internet protocol device records and using facial recognition technology. This use of offline messaging apps has been observed in protests globally and during natural disasters.

BitTorrent исполнилось 25 лет. Как программа одного человека изменила интернет и поставила Голливуд в тупик

On July 2, 2001, Bram Cohen announced the operational status of his program, BitTorrent, on a mailing list for peer-to-peer network developers. BitTorrent revolutionized file sharing by segmenting files into smaller pieces, allowing users to download from multiple sources simultaneously and share already downloaded data, which improved download speeds as file popularity increased. Unlike earlier peer-to-peer networks, BitTorrent did not have a built-in catalog, relying on external websites for users to locate torrents. The first major torrent catalog, Suprnova, emerged in 2002, followed by The Pirate Bay in 2003, making the protocol widely accessible. By 2004, BitTorrent accounted for nearly a third of all internet traffic. In 2004, Cohen founded BitTorrent Inc., which acquired the client µTorrent in 2006. The company launched the BitTorrent Entertainment Network in 2007, but it closed in 2008 due to competition from free pirated content. BitTorrent Inc. later explored various technologies but struggled to establish a sustainable business model. The protocol evolved with decentralization features like the distributed hash table (DHT) and magnet links. In 2018, BitTorrent was acquired by the blockchain project TRON for an estimated 0 million. BitTorrent Inc. claims around 54 million active users per month, with additional users on independent clients. Despite a decline in torrent traffic from its peak, the network has been experiencing growth, attributed to rising streaming costs and fragmented content availability.

Active Exploitation Alert: Fake Bahrain Alert App Deploys Advanced Android Surveillance Malware Targeting Gulf Region Users

A cyber-espionage campaign has been identified involving a counterfeit Bahrain Alert Android application designed to surveil individuals in Bahrain and the Gulf region. The app masquerades as an official civil defense tool and employs social engineering tactics to compromise Android devices, extract sensitive data, and maintain remote access. It targets high-value individuals such as activists and journalists, particularly during civil unrest and missile alerts, leveraging trusted government branding to increase infection rates. The malware features a complex, multi-stage architecture with advanced evasion techniques and is distributed through phishing links and malicious websites. It initiates a four-stage infection process, ultimately installing a remote access trojan (RAT) that enables covert surveillance and encrypted communications. The malware can monitor device activity, capture credentials, and intercept communications, while also employing mechanisms to avoid detection and maintain persistence. The campaign primarily targets Bahraini citizens, exploiting fear during crises to encourage app installation. Although there are indications of Russian-speaking developers involved, there is no definitive attribution to a specific nation-state or APT group. Mitigation strategies include monitoring for suspicious app installations, user education on verifying app authenticity, and blocking known malicious domains.

Windows 11’s biggest updates may need multiple reboots, but that’s normal, don’t force shutdown

Users may experience double reboots when installing substantial Windows updates, such as the April and July 2026 Updates, due to factors like Secure Boot and .NET Framework updates. The July 2026 .NET Framework update specifically requires a separate reboot. Microsoft is still rolling out the Secure Boot 2023 certificate update, which may also lead to multiple reboots. Users are advised not to panic during these reboots and to allow the system time to complete the installation process. Additionally, Microsoft has warned against delaying updates for more than three days due to increasing update sizes related to security vulnerabilities. Some users may encounter SCEP certificate errors in the Event Viewer after the July 2026 Update, but these errors do not indicate a failure of the update process.
