Windows 11 Spotted Keeping Thumbnails of Deleted Photos

Windows 11 uses a thumbnail caching mechanism to store previews of images in specific databases located in %LocalAppData%MicrosoftWindowsExplorer, such as thumbcache32.db and thumbcache1024.db. When a user deletes an image, the corresponding thumbnail may remain in the cache, as deletion does not automatically remove it from the thumbnail database. The cache retains only reduced versions of images, not the original files, which is significant in digital forensics where thumbnails can provide insights even when original files are missing. Users can manage their thumbnail cache using the cleanmgr tool to clear saved thumbnails or disable thumbnail caching through the Local Group Policy Editor or File Explorer settings.

AI Is Changing Antivirus From File Matching to Behaviour-Based Malware Detection

Artificial intelligence is transforming malware detection by moving away from traditional file signature reliance to analyzing program actions. Antivirus software previously used signatures to identify known threats, but the rapid emergence of over 450,000 new malware samples daily complicates this method. Attackers now employ techniques like repacking and encryption to evade detection, prompting the need for machine-learning and behavioral techniques for better protection. Modern detection systems assess multiple characteristics of executable files, including their behavior, to identify potential threats, even if they lack recognized signatures. Microsoft's Project Ire exemplifies advanced detection capabilities, functioning as an automated malware analyst that evaluates unknown binaries based on their behavior. Additionally, modern endpoint-security products leverage cloud systems to analyze data from multiple devices, enhancing threat detection through shared intelligence. However, AI detection can still produce false positives and is susceptible to manipulation by attackers. Therefore, effective security systems require a combination of traditional measures, behavioral monitoring, machine learning, and human analysis to navigate complex threats.

Best Ransomware Protection 2026: Tested and Ranked

Ransomware protection is best approached as a layered strategy rather than relying on a single solution. The effectiveness of software is significantly enhanced by maintaining a well-managed backup that is disconnected during an attack. Five tools were evaluated based on their default settings, focusing on behavioral detection, protected folders, file rollback, and real-time protection. 1. Norton 360: Rated as the best overall ransomware protection, it offers comprehensive features including behavioral monitoring, protected folders with dual alert modes, and 50 GB of cloud backup within a single subscription. It has a perfect score in advanced threat assessments. 2. Bitdefender: Recognized for its file rollback and remediation capabilities, it provides an effective "undo" feature that restores files, although this feature is turned off by default. 3. Avast One Free: The best free ransomware protection option, it includes a dedicated shield on the free Windows tier and has achieved a perfect score in advanced threat assessments. 4. NordVPN Threat Protection Pro: Best for blocking the delivery route of ransomware, it prevents downloads before encryption starts but cannot stop the process once it has begun. 5. McAfee: Best for protecting multiple devices simultaneously, it offers unlimited device coverage on most plans with integrated ransomware defense in its scanning engine. Modern ransomware protection software has shifted from signature matching to focusing on monitoring the behavior of processes interacting with files. The four essential layers of protection include behavioral monitoring, protected folders, automatic file rollback, and backup. Most users do not need a separate anti-ransomware product, as these features are typically included in main antivirus suites, with the key consideration being whether these features are activated. The rankings of the tools were based on whether the ransomware protection layer is enabled by default, the extent of file recovery when intervention occurs, and the frequency of false positives during normal use. - Norton 360: Best overall, with protection enabled by default and a perfect score in advanced threat testing. - Bitdefender: Best for file rollback, but the rollback feature is disabled by default. - Avast One Free: Best free option, with a perfect score in advanced threat assessments but lacks rollback capabilities. - NordVPN Threat Protection Pro: Effective at blocking malware downloads but does not provide rollback or backup features. - McAfee: Suitable for families with multiple devices, offering automatic backup of flagged files but lacks user-configurable protected folder options. The effectiveness of ransomware protection tools is primarily assessed through behavioral responses rather than library matching. Backup remains a critical layer of defense, functioning even when other layers fail.

Violent criminals keep escaping justice, but I sure am taking some nice photos of evidence in this crime scene simulator

Chris Livingston is exploring job simulations to find a new career and is currently engaged in a Forensics: Crime Scene Detective simulation. His understanding of crime scene investigations is influenced by media portrayals, particularly CSI: Miami. In his first case, he successfully solves a bullet-in-wall scenario, scoring 100% after several attempts. However, he struggles with a coin burglary case, ultimately scoring only 16 out of 100 due to missed evidence and failed analyses. He reflects on whether he would enjoy being a real-life crime scene detective, finding the documentation appealing but the reality of blood and violence unappealing. Livingston appreciates the game's approach to failure, which allows for learning from mistakes.

Active Exploitation of Critical CVE-2026-20253 in Splunk Enterprise: Unauthenticated RCE via PostgreSQL Sidecar Service

A critical security vulnerability, SVD-2026-0603 (CVE-2026-20253), has been identified in Splunk Enterprise versions 10.0.0 through 10.0.6 and 10.2.0 through 10.2.3. This flaw allows unauthenticated, remote attackers to create or truncate arbitrary files on the host system by exploiting the PostgreSQL Sidecar Service endpoints. The vulnerability is actively exploited, with public proof-of-concept code available, and has been added to the CISA Known Exploited Vulnerabilities (KEV) list. Successful exploitation can lead to full remote code execution (RCE) as the Splunk user. The vulnerability arises from inadequate authentication controls on the PostgreSQL Sidecar Service endpoints, specifically /v1/postgres/recovery/backup and /v1/postgres/recovery/restore, which are accessible without authentication. It is classified under CWE-306: Missing Authentication for Critical Function and has a CVSS v3.1 base score of 9.8 (Critical). Attackers can exploit the vulnerability by sending crafted HTTP POST requests to the exposed endpoints, allowing them to create or truncate files and potentially execute malicious scripts. Indicators of compromise include unexpected files in directories such as /tmp/ or /opt/splunk/var/run/supervisor/pkg-run/, modified Splunk Python scripts, and unusual outbound connections from Splunk to unknown PostgreSQL servers. The vulnerability aligns with several MITRE ATT&CK techniques, including T1190 (Exploit Public-Facing Application) and T1059 (Command and Scripting Interpreter). Active exploitation of CVE-2026-20253 has been confirmed, and it is likely that both opportunistic cybercriminals and sophisticated threat actors will use this exploit. The affected versions of Splunk Enterprise are 10.2.0 through 10.2.3 and 10.0.0 through 10.0.6, with the issue resolved in versions 10.2.4 and 10.0.7. Organizations are advised to upgrade to fixed versions or disable the PostgreSQL Sidecar Service as a mitigation strategy.
