Your Antivirus Has A Blind Spot, And Advanced Persistent Threats (APTs) Know Where It Is

Advanced Persistent Threats (APTs) are a type of cyber threat characterized by long-term infiltration aimed at stealing sensitive data or surveilling communications, often orchestrated by well-funded groups. Unlike traditional malware, which seeks immediate disruption, APTs employ a methodical approach, spending weeks mapping out networks and identifying valuable credentials. Traditional antivirus solutions often fail to detect APTs because they rely on signature-based detection, which is ineffective against custom malware. APTs frequently use legitimate tools already present on systems, making detection challenging, and some forms of APTs operate directly from memory without writing to disk, evading traditional scans. To combat APTs, a multifaceted strategy is recommended, including behavioral detection, network monitoring for unusual patterns, and a mindset of skepticism towards all network activities.

Microsoft Warns of GigaWiper Backdoor Built to Destroy Windows PCs

Microsoft has unveiled a destructive Windows backdoor named GigaWiper, which allows operators remote control over compromised systems to execute irreversible damage. GigaWiper originated from cyberattacks in October 2025 and is a composite of code from at least three malware families. It maintains its presence through a scheduled task disguised as “OneDrive Update,” executing at startup and every minute. GigaWiper can obliterate partition information, overwrite physical drives, and restart systems. It also mimics ransomware by encrypting files with the .candy extension, using randomly generated keys that are not stored, making recovery impossible. The malware has connections to the Crucio ransomware and resembles FlockWiper, with rewritten code in Go. GigaWiper features 20 command codes for various functions, including executing PowerShell instructions, managing processes, capturing screenshots, and remote access similar to VNC. It can remain on a system for surveillance until its destructive functions are activated. Microsoft Defender includes detection capabilities for GigaWiper, and users are advised to enable tamper protection and monitor for suspicious activities.

7 Habits That Are More Important Than Using Antivirus on Your Phone

Antivirus software was once standard on personal computers, but modern smartphones have evolved with enhanced security measures from Apple and Google, making them less vulnerable to traditional malware. Smartphones isolate applications, allowing them only to access user-permitted information, and if a malicious app infiltrates, it faces significant challenges due to built-in defenses. Apple requires thorough vetting of apps through the App Store, which enhances security but limits antivirus capabilities. Android allows sideloading apps from outside the Google Play Store, which introduces risks but also includes built-in security features like Google Play Protect and regular updates. Despite these advancements, smartphones can still be compromised, and cybercriminals increasingly target user accounts through phishing tactics rather than malware. Security experts recommend focusing on phishing awareness, strong passwords, and two-factor authentication. For enhanced security, users should keep devices updated, download apps from official sources, review app permissions, use strong passwords, utilize a password manager, enable two-factor authentication, and be cautious with unexpected communications. While most users may not need antivirus apps, those who frequently sideload or download from unfamiliar sites may benefit from additional security tools.

Ex-Microsoft engineer rebuilds Notepad in 2.5KB using nothing but stuff Windows already had

Dave Plummer, a former Microsoft engineer, is recreating Notepad in 2.5 kilobytes with a project called TinyRetroPad, which includes features like Open, Save, Find and Replace, printing, font selection, word wrap, and unsaved changes prompt. TinyRetroPad leverages existing Windows infrastructure, utilizing built-in resources to function efficiently. It is based on Matt Power’s Dave’s Tiny Editor and operates as a wrapper around RICHEDIT50W. The size of TinyRetroPad increased with each feature added, reaching 2,476 bytes with printing. The project uses Crinkler, a compression linker, to optimize the executable. TinyRetroPad currently lacks a dedicated Releases page and may trigger false positives from antivirus software. Users have reported issues such as excessive memory usage and compatibility problems with older Windows versions. In contrast, the modern Notepad in Windows 11 has grown to approximately 352KB, with a total disk footprint nearing 5MB, leading to user backlash over its complexity. Windows 11 LTSC retains the classic Notepad, while TinyRetroPad aims to demonstrate the potential of leveraging existing OS capabilities rather than adding unnecessary features.
