Google announced new AI-powered defenses against scam messages and call-forwarding abuse on Android, currently rolling out to eligible devices. The new measures aim to address the increased sophistication of scams targeting mobile users, including fraudulent bank alerts and voice-cloning attacks. “Mobile scams have evolved far beyond basic robocalls and phishing texts, turning into sophisticated operations that use spoofed numbers, fake bank alerts, and AI voice cloning,” Google says. “With scams growing harder to spot, it’s nearly impossible for users to catch every red flag themselves,” added the tech giant. Google says its existing Phone and Messages scam detection flags more than 5 million suspected scam calls and texts monthly, but the new measures are expected to catch even more threats.
U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Palo Alto Networks PAN-OS, Ahsay AhsayCBS, and Cisco Secure Email Gateway flaws to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the following vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog: CVE-2026-0322 Palo Alto Networks PAN-OS Code Injection Vulnerability CVE-2026-76519 Cisco Secure Email Gateway Relative Path Traversal Vulnerability CVE-2026-105133 Ahsay AhsayCBS Improper Authentication Vulnerability CVE-2026-105134 Ahsay AhsayCBS Command Injection Vulnerability Cisco confirmed this week that threat actors are exploiting a critical vulnerability in Cisco Secure Email Gateway, tracked as CVE-2026-76519 (CVSS score of 9.8). An attacker can exploit the flaw by sending a crafted email attachment through the gateway and, if it lands right, writing arbitrary files to the underlying operating system. The flaw CVE-2026-0322 (CVSS score: 8.6) is a high-severity code injection vulnerability in the management interface of Palo Alto Networks PAN-OS. It could allow an authenticated attacker with network access and high-level privileges to execute arbitrary code with root privileges on an affected firewall. The vulnerability affects PA-Series and VM-Series firewalls and Panorama appliances. Palo Alto Networks confirmed that limited exploitation has been observed targeting the management interface. The company recommends restricting access to trusted internal IP addresses and installing the relevant security updates. The flaw CVE-2026-105133 (CVSS score: 5.5) is an improper authentication vulnerability in AhsayCBS, a backup management platform. The flaw affects the checkSysPwd function in the product’s API and could allow a remote attacker to bypass authentication by manipulating the random parameter. Starting on October 7, 2026, attackers used it to bypass authentication before exploiting a second vulnerability, CVE-2026-105134, to execute commands on affected servers. Huntress reported that at least five organizations had been targeted by October 8. The flaw CVE-2026-105134 (CVSS score: 9.3) is a critical operating system command injection vulnerability in the Replication Receiver component of AhsayCBS. The flaw affects the /rps/api/json/UpdateReceivers.do endpoint and could allow an unauthenticated remote attacker to execute arbitrary commands on the underlying system. The vulnerability is being actively exploited in the wild. Attackers have chained it with CVE-2026-105133 to gain remote code execution with NT AUTHORITY\SYSTEM privileges, deploy JSP web shells and install XMRig cryptocurrency miners disguised as Microsoft Edge processes. Huntress observed attacks against at least five organizations by October 8, 2026. According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog. Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure. CISA orders federal agencies to fix the flaws by October 17, 2026.

A proxyjacking campaign has impacted devices in 34 countries, monetizing victims’ internet connections through a commercial residential proxy network. The operator installed Pawns.app, a legitimate bandwidth-sharing application that lets users earn money by sharing their internet connections, on devices without the owners’ consent. Pawns.app account holders are rewarded for allowing traffic from other users to flow through their network, provided it runs on trusted, non-blocking IP addresses. By installing the app on multiple systems, the attacker likely accumulated larger payouts. Threat intelligence company GreyNoise discovered the campaign while investigating suspicious activity at an unnamed organization, and identified at least 143 compromised devices worldwide. According to the researchers, the attacker leveraged several vulnerabilities to breach edge devices and install the Pawns.app software:
Singapore-based Ahsay Backup has released security updates to address two security flaws in AhsayCBS that have been exploited by bad actors to drop web shells and XMRig cryptocurrency miners. The vulnerabilities in question are CVE-2026-105133 and CVE-2026-105134, which could be chained to sidestep authentication and execute arbitrary commands on affected systems. In a report published earlier
Palo Alto Networks has released security updates for a high-severity PAN-OS RCE zero-day, tracked as CVE-2026-0322, that has been exploited in attacks targeting firewalls. The vulnerability affects the PAN-OS management interface and lets authenticated attackers with network access execute code as root on vulnerable devices. Palo Alto Networks confirmed in a security advisory published Wednesday that it has seen limited exploitation of the flaw in attacks. "Very limited exploitation has been observed targeting the Palo Alto Networks management interface," the company said. The vulnerability has a severity score of 8.6 and affects PA-Series and VM-Series firewalls, as well as Panorama virtual and M-Series appliances. Palo Alto says Cloud NGFW and Prisma Access are not affected. To exploit the vulnerability, attackers need existing credentials and network access to the PAN-OS management interface.
Microsoft has resolved a known issue that caused Always On VPN connection issues after installing the September 2026 Windows 11 security updates. The Always On VPN remote access solution replaced the legacy DirectAccess technology and works with domain-joined, non-domain-joined, and Microsoft Entra ID–joined Windows 10, Windows 11, and Windows Server devices. Always On VPN runs in the background and automatically establishes a secure tunnel back to the corporate network whenever a device connects to the internet. As Microsoft first acknowledged in a service alert sent to IT administrators in late September, the bug triggered Always On VPN failures if the initial connection fails (e.g., when using automatic protocol selection with IKEv2 and SSTP) on up-to-date systems running Windows 11 24H2 and later.
AI-powered penetration testing can uncover complex attack paths, but safety restrictions and network limitations leave many assets and vulnerabilities untested. Picus Security explains how combining agentic pentesting with exposure validation and breach simulation can help close these gaps.
A massive cybercriminal ecosystem facilitating more than a billion malicious messages targeting over 75,000 organizations across 150 countries has been disrupted by law enforcement agencies and partners worldwide. Since the start of the year, more than 750 million malicious messages have been aimed at Microsoft customers via email and SMS texts. Following an investigation initiated by Microsoft and Japan’s National Police Agency (NPA) into a wave of fraudulent activity, "a sprawling Chinese-language cybercrime marketplace" was discovered, with tools and services for phishing campaigns. The investigators traced the malicious activity to YAM Store (Storm-3119), an underground infrastructure marketplace, then linked it to the CoGUI, Haozi, and Iron Man System phishing kits, collectively tracked as Storm-2990.
A new Android malware called Hirudo steals bank account credentials by replacing legitimate banking apps with modified versions that disable security checks.
Cybersecurity researchers have disclosed details of a new Android banking trojan called Hirudo that works by replacing legitimate banking apps with purpose-built patched versions designed to bypass security checks from inside the app itself, marking a new escalation in financial fraud. Dutch mobile security company ThreatFabric said it identified replacements for eight Indonesian banking
