Key service for malware developers taken offline

The takedown of AVCheck, a major Counter Antivirus (CAV) service used by cybercriminals, disrupts their ability to test malware against antivirus detection, thereby hindering successful attacks. Matthijs Jaspers from the High Tech Crime Team highlighted that this operation is crucial in combating organized cybercrime, as it prevents early-stage criminal activities. The investigation revealed connections between AVCheck and other services like Cryptor.biz and Crypt.guru. Additionally, law enforcement has taken proactive measures, including deploying a fake login page to deter AVCheck users and collaborating with Project Melissa to target malware services. The need for coordinated efforts among various sectors is emphasized to effectively combat cybercrime.

Study offers a national report on antivirus software trends

Nearly half of Mac users have encountered viruses despite having protective software installed, challenging the belief that Apple products are immune to malware. The report highlights that 71% of Android users have antivirus software, but only 49% seek third-party tools. More than half of Americans do not use additional security measures beyond antivirus. Among iOS users, 38% are unaware of third-party antivirus options. While 84% have antivirus on computers, only 68% have it on smartphones and 60% on tablets. Despite widespread adoption, only 16% of antivirus users feel their software is ineffective. The virus encounter rates are 44% for Mac users, 36% for Windows users, and 30% for other platforms.

Microsoft Copilot+ Recall: who should disable it, and how

Microsoft's Recall feature for Copilot+ PCs was initially announced a year ago but delayed due to privacy concerns raised by cybersecurity experts. The updated version was released in April 2025 for Windows Insider Preview builds and rolled out more broadly in May. Key updates include requiring user permission for activation, encrypting database files with hardware-based Trusted Platform Module (TPM), and implementing a filter to prevent saving sensitive information. Recall is enabled on a per-user basis, can be uninstalled, does not require a Microsoft account, and processes data locally. However, it still has vulnerabilities, such as allowing access with a regular Windows PIN after initial biometric authentication and failing to consistently filter sensitive data. Recall can log interactions during calls and capture self-destructing messages, posing privacy risks. It can impact performance and battery life, especially during gaming. Users handling sensitive data or frequently using video conferencing may want to disable or remove Recall. Instructions for disabling or removing Recall are provided, along with precautions for those who choose to use it.

Microsoft starts final Windows Recall testing before rollout

Microsoft is gradually introducing its AI-powered Windows Recall feature to Insiders in the Release Preview channel, with plans to extend it to all Windows users with Copilot+ PCs. Recall captures screenshots of active windows at regular intervals, allowing Windows 11 users to search for text within these snapshots using natural language. Users can opt-in to save snapshots and must authenticate via Windows Hello to access their data. Recall is currently being rolled out to Windows 11 Insiders with Build 26100.3902 (KB5055627). The feature faced privacy concerns upon its introduction in May 2024, leading Microsoft to implement measures to enhance user privacy, such as filtering out sensitive information and allowing users to adjust storage settings. The rollout of the first Recall preview began in November 2024 for Snapdragon Copilot+ PCs, followed by Intel and AMD Copilot+ PCs a month later.

What Is Signal, the App Used by Trump Staff, and Is It Safe?

The Trump administration is under scrutiny for officials using the messaging app Signal for discussions about sensitive military operations, revealed in an article by Jeffrey Goldberg on March 24. Secretary of Defense Pete Hegseth and others discussed military actions in Yemen via Signal, despite prior warnings from the U.S. government against using such applications for official communications. Democratic lawmakers, including Senator Chuck Schumer, are calling for an investigation into potential national security breaches. Signal, launched in 2014, emphasizes privacy through end-to-end encryption and has gained popularity among activists. However, its use in government contexts is contentious, with previous reprimands for non-compliance with federal record preservation requirements. Concerns have been raised about sharing sensitive information on Signal, although intelligence officials stated that no classified information was exchanged in the Trump officials' conversations. The Pentagon has warned military personnel about using Signal due to risks from Russian hackers, and experts suggest that government-specific communication tools would provide a higher level of security.

Kapersky Internet Security and Antivirus Review 2025

Kaspersky Anti-Virus features a user-friendly interface organized into four main sections: scan, database update, reports, and an on-screen keyboard. The on-screen keyboard enhances privacy when entering sensitive data, protecting against keyloggers. The Reports section provides an overview of scanning activities and includes data from the System Watcher feature, which can mitigate malware attacks. The Database Update section allows for automatic updates to keep the software current with the latest threats, with options for manual scheduling. The scan menu includes a Quick Scan that completes in about seven minutes and a Full Scan that can take several hours; both scans detected all actual malware during testing. Additional scanning options include selective scans and removable drive scans. The software allows for high customization, including a "Gamer Mode" that defers scheduled scans during full-screen applications. It also postpones tasks during battery operation or high disk activity and offers an option to opt out of promotional offers.

Evolving Snake Keylogger Variant Targets Windows Users

Cybersecurity researchers at Fortinet have identified a new variant of the Snake Keylogger malware, which has blocked over 280 million infection attempts globally. This malware captures sensitive user information, including credentials and browser data, and has the highest infection rates in China, Turkey, Indonesia, Taiwan, and Spain. The Snake Keylogger operates in three phases: distribution through phishing emails, data collection by capturing keystrokes and extracting credentials from browsers, and data transmission to command-and-control servers via encrypted channels. It employs advanced evasion techniques, such as process hollowing and persistence mechanisms, to operate stealthily. The malware uses obfuscation tools like AutoIt scripting to evade antivirus defenses and specifically targets browser-stored credentials. Security experts recommend caution with emails, using updated antivirus software, and regular patching of systems to mitigate risks.
