🔒 Microsoft has expanded the .NET Bounty Program, increasing maximum awards to $40,000 and broadening coverage to include all supported .NET and ASP.NET versions, adjacent technologies like F#, templates, and GitHub Actions. The program simplifies award tiers, aligns impact categories with other Microsoft bounty programs, and defines report quality as complete (working exploit) or not complete, encouraging detailed, actionable submissions.

ToolShell SharePoint Zero-Days Exploited in the Wild

🔒 Microsoft and ESET reported active exploitation of a SharePoint Server vulnerability cluster called ToolShell, comprising CVE-2025-53770 (remote code execution) and CVE-2025-53771 (server spoofing). Attacks began on July 17, 2025, and target on-prem SharePoint Subscription Edition, SharePoint 2019 and SharePoint 2016; SharePoint Online is not affected. Operators deployed webshells — notably spinstall0.aspx (detected as MSIL/Webshell.JS) and several ghostfile*.aspx samples — to bypass MFA/SSO, exfiltrate data and move laterally across integrated Microsoft services. Microsoft and ESET confirmed patches were released on July 22, and ESET published IoCs and telemetry to assist defenders.

Fake Reservation Links Target Travel and Hospitality Industry

✈️ A longtime threat group tracked as TA558 has resumed phishing campaigns that spoof hotel or reservation notices to lure travelers into downloading malware. Campaigns increasingly deliver ISO and RAR container files via URLs that, when decompressed, execute batch scripts and PowerShell helpers to fetch RATs such as AsyncRAT. TA558 has shifted from macro-laden Office documents to containerized attachments after Microsoft limited macros. Travel organizations and customers should be wary of unexpected reservation emails and avoid opening unknown archives.
