AI is already part of digital forensics and incident response work, with or without a policy in place to govern it. The issue is that these tools are growing more confident in their own output faster than practitioners are developing reliable ways to verify it. Without governance models and validation standards in place, that gap compounds and rarely stays contained to a workstation: an
The credential-theft campaign known as GhostAction has ramped up, targeting more than 30,000 repositories across 3,000 users and organizations. The spike, according to GitGuardian, was observed on October 8 and 9, 2026. "This resulted from compromising the GitHub accounts of about 1,900 users. It attempted to extract 3,174 secrets from public repositories' CI," security researchers Gaetan
Threat actors are exploiting a critical security flaw in Langflow, according to an alert from Previdian. Langflow is an open-source platform that allows developers to build artificial intelligence (AI) applications and agentic workflows. In February 2025, DataStax, the parent company of Langflow, was acquired by IBM. The vulnerability in question is CVE-2026-105740 (CVSS score: 9.9), a case of
Palo Alto Networks on Wednesday issued security updates for a high-severity flaw in PAN-OS software that has come under active exploitation. The vulnerability, tracked as CVE-2026-0322 (CVSS score: 8.6), is a case of remote code execution in the management interface. "A remote code execution (RCE) vulnerability in the management interface of Palo Alto Networks PAN-OS software enables an
We investigated an intrusion where attackers exploited CVE-2024-47575 to target 500+ firewalls and deploy PEERSTITCH, a memory-resident ARM64 malware. The post Unit 42 Uncovers PEERSTITCH, a Stealthy FortiGate Implant appeared first on Unit 42.
U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Microsoft Windows Shell flaw to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a Microsoft Windows Shell flaw, tracked as CVE-2026-96951 (CVSS score of 8.8), to its Known Exploited Vulnerabilities (KEV) catalog. Microsoft Patch Tuesday security updates for October 2026 address a record 1,415 vulnerabilities, including a zero-day under active attack. The flaw, tracked as CVE-2026-96951, is a Windows Shell command injection vulnerability that allows an unauthorized attacker to bypass security protections over a network. Exploitation can evade Mark of the Web (MOTW) defenses, which help protect users from potentially dangerous files downloaded from the internet. Microsoft confirmed that the flaw is being actively exploited. “An attacker who successfully exploited the vulnerability could evade Mark of the Web (MOTW) defenses.” reads the advisory. “In an email or instant message attack scenario, the attacker could send the targeted user a specially crafted file that is designed to exploit the vulnerability. In any case an attacker would have no way to force a user to view attacker-controlled content. Instead, an attacker would have to convince a user to take action. For example, an attacker could entice a user to either click a link that directs the user to the attacker’s site or send a malicious attachment.” 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 flaw by October 16, 2026. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) also added an Ivanti Connect Secure FortiMail flaw, tracked as CVE-2026-104935 (CVSS score of 8.6), to its Kev Catalog. The vulnerability is an authentication bypass issue caused by spoofing in ICS versions before 25.1.3.0 that could allow a remote, unauthenticated attacker to execute arbitrary commands. ICS versions 22.7R2.14 and earlier are not affected. Follow me on Twitter: @securityaffairs and Facebook and Mastodon Pierluigi Paganini (SecurityAffairs – hacking, CISA)
The U.S. Department of Justice (DoJ) has disrupted the Famous Chollima threat group’s operations by arresting two suspects, charging 14 individuals, and seizing nearly 187 laptops used in North Korean remote IT worker schemes. Famous Chollima (a.k.a. WageMole) is commonly tracked as a North Korean threat actor associated with fraudulent IT-worker schemes that generate revenue for the DPRK regime. Because North Korea is subject to extensive international sanctions, its operatives seek technology jobs at companies worldwide, often using stolen, rented, or fabricated identities. In some cases, they also attempt to compromise employers’ networks to steal sensitive data, deploy malware, or obtain cryptocurrency and other assets. As part of an operation in Texas codenamed “Lonestar Roundup,” the FBI searched 40 residences suspected of hosting laptop farms between September 21 and 25.
Attackers are exploiting a critical flaw in Cisco Secure Email Gateway that lets a sender with no login write files to the appliance's operating system, Cisco said in an advisory on Wednesday. The attacker sends an email with a crafted attachment through the gateway and, if it succeeds, could then run commands as root. The appliance filters an organization's email for spam, malware,
Ledger is asking resellers and distributors in Southeast Asia and Hong Kong to halt wallet sales and remove products from shelves while it investigates hardware implant incidents. The company announced the decision in response to discovering that devices purchased from CryptoBilis had been modified to steal seed phrases used to access crypto assets and send them to an unauthorized party over an LTE connection. Ledger sells physical cryptocurrency wallets that securely store private keys used for managing and authorizing digital asset transactions. Following reports of cryptocurrency losses from multiple users, Ledger launched an investigation on October 9 and confirmed that some devices sold by CryptoBilis had been tampered with. Yesterday, Ledger’s Donjon security arm shared more details about the hardware implant found inside devices from the reseller , largely confirming earlier reports by Mark Karpelès and Tibane Labs.
Cisco has patched another actively exploited zero-day flaw in its Secure Email Gateway (SEG) that lets remote unauthenticated attackers execute commands with root privileges. Tracked as CVE-2026-76519, this vulnerability stems from a relative path traversal weakness in SEG's Advanced Malware Protection (AMP) feature, caused by improper handling of email attachments. Threat actors can exploit this issue by sending an email with a maliciously crafted attachment through an unpatched device. "A successful exploit could allow the attacker to write arbitrary files and execute commands with root privileges on the underlying operating system," Cisco said in a Wednesday advisory. "In October 2026, the Cisco PSIRT became aware of active exploitation of this vulnerability." CVE-2026-76519 affects SEG instances where the File Reputation service is enabled and assigned to a mail policy, and the Content Scanner Tools version is earlier than 25.3.0.5525.
