This vulnerability is comparable to the Rapid Reset attack vector.&lt;/li&gt;&#10;&lt;li&gt;Two vulnerabilities (CVE-2025-8875 and CVE-2025-8876) in N-able N-central remote monitoring and management (RMM) platform are being actively exploited as zero-days. These allow local code execution and command injection after authentication.&lt;/li&gt;&#10;&lt;li&gt;Xerox FreeFlow Core print orchestration software contained path traversal and XML external entity (XXE) injection flaws enabling unauthenticated remote code execution. Patches have been released.&lt;/li&gt;&#10;&lt;li&gt;Researchers demonstrated that passkey (FIDO/WebAuthn) authentication can be bypassed via manipulation of the WebAuthn process, allowing attackers to impersonate users.&lt;/li&gt;&#10;&lt;li&gt;A downgrade attack technique has been shown to allow phishing kits to bypass FIDO authentication, enabling credential theft even with strong authentication mechanisms.&lt;/li&gt;&#10;&lt;/ul&gt;&#10;&lt;h2 id="notable-threat-actor-activity"&gt;Notable Threat Actor Activity&lt;/h2&gt;&#10;&lt;ul&gt;&#10;&lt;li&gt;The Crypto24 ransomware group is targeting large organisations using custom utilities for endpoint detection and response (EDR) evasion, data exfiltration, and file encryption.&lt;/li&gt;&#10;&lt;li&gt;Threat actors are using the CrossC2 command-and-control framework to expand Cobalt Strike Beacon capabilities to Linux and macOS environments, as observed by JPCERT/CC.&lt;/li&gt;&#10;&lt;li&gt;A new Android banking trojan, PhantomCard, is abusing NFC relay attacks, call hijacking, and root exploits to conduct fraudulent transactions.&lt;/li&gt;&#10;&lt;li&gt;A phishing campaign is distributing malware by leveraging a Japanese hiragana character (“ん”) in URLs to impersonate Booking.com, making malicious links appear legitimate.&lt;/li&gt;&#10;&lt;li&gt;Scammers are targeting jobseekers with fake Netflix job offers to steal Facebook login credentials.&lt;/li&gt;&#10;&lt;/ul&gt;&#10;&lt;h2 id="trends-tools-or-tactics-of-interest"&gt;Trends, Tools, or Tactics of Interest&lt;/h2&gt;&#10;&lt;ul&gt;&#10;&lt;li&gt;The Picus Blue Report 2025 notes that only 3% of data exfiltration attempts are stopped, indicating a trend toward stealthy ransomware and infostealer operations focused on data theft rather than encryption.&lt;/li&gt;&#10;&lt;li&gt;MailSniper, a PowerShell tool for Exchange, is being used in red team operations to search mailboxes for credentials, network intelligence, and usernames.&lt;/li&gt;&#10;&lt;li&gt;SNI5GECT research demonstrates the ability to sniff and inject traffic in 5G networks without rogue base stations, highlighting risks to 5G infrastructure.&lt;/li&gt;&#10;&lt;li&gt;Budget constraints are impacting cybersecurity teams, particularly in healthcare, professional services, retail, and hospitality, while financial services, insurance, and tech sectors see budget growth above 5%.&lt;/li&gt;&#10;&lt;li&gt;Google Chrome Enterprise is enhancing browser security for enterprise environments, with a focus on extending protections from browser to operating system.&lt;/li&gt;&#10;&lt;/ul&gt;&#10;&lt;h2 id="regulatory-or-policy-developments"&gt;Regulatory or Policy Developments&lt;/h2&gt;&#10;&lt;ul&gt;&#10;&lt;li&gt;State and local leaders in the US are lobbying Congress for increased cybersecurity resources following federal funding cuts to the Multi-State Information Sharing and Analysis Center (MS-ISAC), potentially affecting over 18,000 organisations’ access to basic cybersecurity services.&lt;/li&gt;&#10;&lt;/ul&gt;</description></item></channel></rss>
