A local privilege escalation exploit published today gains root on OpenBSD 7.9 by chaining a roughly 37-year-old integer overflow with a separate kernel flaw, bypassing OpenBSD's KARL kernel-address randomization and its SMAP and SMEP hardware protections. Security firm Calif, which found and reported the flaws, published a detailed writeup and full proof-of-concept code after OpenBSD shipped
Attackers repeatedly changed the files that AOMEI Backupper fetches from the vendor's own update servers, in windows of five to ten minutes at a time between May and July 2026, so that any copy of the Windows backup program that checked for an update during one of those windows would download and run a backdoor.

Cybersecurity researchers have disclosed details of an advanced persistent threat (APT) spear-phishing campaign that has targeted individuals affiliated with Taiwan research organizations to direct victims to an adversary-in-the-middle (AitM) phishing framework designed to harvest their Google account credentials and multi-factor authentication (MFA) codes. The activity is being tracked by
OpenAI has disclosed seven new incidents in which its artificial intelligence (AI) models exhibited misaligned behavior, including one case where its research model, after not having funds on an Ethereum test network, spent test cryptocurrency from a third-party's wallet without authorization to complete a coding task. The incident, the AI company said, involved an internal research model part
The China-nexus cyber espionage group tracked as Armory Castle (previously UNC5221 or Warp Panda) exploited a newly disclosed security flaw in BeyondTrust Remote Support (formerly Bomgar) as a zero-day in late August 2026. The vulnerability, tracked as CVE-2026-102764 (CVSS score: 9.3), is a case of improper origin validation in an internal messaging component that could be exploited by a
AI agents being tested online reached the live systems of Indian organizations and read business records, including personal data and confidential material, CERT-In said in an advisory on October 15. The agents went beyond their assigned tasks, and none of the organizations detected the unauthorized access. After internal reviews, the AI companies whose models were being tested
A suspected advanced threat actor has been observed exploiting a security flaw in Fortinet FortiOS to deliver a previously unreported memory-resident ARM64 malware known as PEERSTITCH. The attack involves the exploitation of CVE-2025-61624 (CVSS score: 5.4), a path traversal flaw in the command line interpreter of FortiOS, FortiPAM, FortiProxy, and FortiSwitchManager that could allow a
Our analysis an AI-powered espionage campaign targeting government Linux infrastructure with custom malware, web shells, and advanced credential theft. The post AI-Powered Espionage Campaign Targets Government Linux Infrastructure appeared first on Unit 42.
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.
