Patch for Windows Defender 0-day could allow attackers to fill hard disk

A recent Microsoft patch addressing the RoguePlanet vulnerability (CVE-2026-50656) in its Defender security engine has raised concerns about disk space issues for Windows users. The vulnerability allows remote attackers to gain administrative control over Windows 10 and 11 systems. The patch, which updates the Microsoft Malware Protection Engine, is automatically installed without user action. However, it may enable attackers to fill a hard drive by writing excessive data due to changes in the mpengine.dll driver. These changes can cause a data leak of 8 bytes when opening a file and involve new functionalities in SpyNet, which could lead to mass file-writing behavior. Typically, Defender limits file sizes during scanning, but the spynet functions may maintain a local copy of the Zone.Identifier Alternate Data Stream file, potentially exhausting disk space.

Why identity theft protection now matters just as much as antivirus

Cybercrime has shifted focus from targeting individual devices to stealing credentials and personal data for identity theft. In 2024, consumer losses due to fraud reached billion, a 25% increase from the previous year, with over a million identity theft reports filed. Stolen passwords and session cookies are central to most breaches, making credential theft the primary enabler of attacks. Password reuse is a significant vulnerability, with 65% of individuals reusing passwords, leading to increased risk of account takeovers through credential stuffing. Bitdefender offers features like Scam Protection Pro, which protects against fraud across email, chat, and SMS, and identity monitoring in Ultimate Security that alerts users to data leaks in real-time. In 2025, researchers identified approximately 2 billion unique leaked credentials, emphasizing the need for identity protection alongside traditional antivirus solutions.

Meta pauses controversial employee-tracking program after security review

Meta has suspended its employee-tracking program after an internal security review revealed excessive accessibility to sensitive data collected from staff laptops. The program, part of the Model Capability Initiative (MCI), aimed to gather detailed information on employee interactions with work devices, including mouse movements, click locations, keystrokes, and screen content. Concerns arose regarding the privacy and security of the collected data, which included AI prompts, transcriptions, private conversations, and performance-related information. The initiative faced backlash, particularly after an engineer criticized "laptop surveillance," leading to a petition for its termination. The monitoring software was deployed on US workers’ laptops without an opt-out option, capturing comprehensive behavioral datasets. The situation highlighted significant legal and regulatory challenges, as well as the risks associated with managing sensitive data. Access controls, data minimization, and retention policies are critical to mitigate potential breaches.

Unsecured AI apps are leaking personal data of Android users

Many unregulated or inadequately secured AI applications on platforms like the Google Play store pose significant privacy risks to users. A specific Android application, "Video AI Art Generator & Maker," linked to a data leak, compromised 1.5 million user images, over 385,000 videos, and millions of AI-generated media files due to a misconfiguration in a Google Cloud Storage bucket. Another app, IDMerit, exposed sensitive know-your-customer data from users in 25 countries, including full names, addresses, birthdates, IDs, and contact information, totaling a terabyte of data. Both developers addressed the vulnerabilities after being alerted by researchers. However, cybersecurity experts warn that lax security among AI applications is a widespread issue, with 72 percent of analyzed Google Play apps exhibiting security flaws, including the practice of "hardcoding secrets" in their source code.

Why Should Small Businesses Invest In Antivirus Protection?

53% of UK businesses experience cybercrime attempts at least once a month. 70% of business owners anticipate a cyber attack in the near future, but only about 35% feel prepared. 43% of cyberattacks are directed at small businesses, and over half of these may face closure due to the damage. Antivirus software can prevent data breaches, is cost-effective, reduces the likelihood of ransomware, and protects devices of remote workers.
