mSeven Software is warning current and former mSecure password manager customers to change passwords, reset two-factor authentication, and remove passkeys following a cyberattack that reportedly exposed an encrypted customer database. [...]
A 3AM ransomware affiliate targeted a school estate in the UK and successfully encrypted around 37 of nearly 50 machines reached from an unmanaged host. [...]
Synology is urging customers to update the DiskStation Manager (DSM) software powering its Network Attached Storage (NAS) devices following ransomware attacks. The Taiwanese vendor said it observed threat actors exploiting a vulnerability patched in December 2024 to target devices running outdated versions of DSM. "These attacks aim to encrypt data and extort ransom," it said in a statement
A critical flaw in Canonical's LXD and MicroCloud let an attacker log in as a trusted client without holding that client's private key. To do it, the attacker had to reach their HTTPS API over the network and have the trusted client's public certificate. Once in, the attacker would act as that client, with access to the cluster and its virtual machines. If the impersonated account is
A malicious ChatGPT share link could run an attacker's code in the logged-in session of anyone who opened it, allowing them to read their private conversations, researchers at the security firm Parameter showed. The researchers reported the flaw through OpenAI's bug bounty program on October 18, and OpenAI fixed it eight days later and rated it P1, its most serious category.
Chinese state-sponsored threat actors have been observed using a Go-based artificial intelligence (AI)-powered penetration testing framework called ARTEX in attacks aimed at high-value targets simultaneously. The activity has been attributed by CrowdStrike to a China-based "targeted intrusion adversary" it tracks under the moniker Vapor Panda (previously VexatiousTemper). First identified in
Cisco released security updates to patch a denial-of-service zero-day in Adaptive Security Appliance (ASA) and Threat Defense (FTD) software that attackers are exploiting to remotely crash vulnerable firewall devices. [...]
Hackers exploited a critical Cisco Catalyst SD-WAN flaw, fixed in February, to plant custom malware inside the systems that control an organization's SD-WAN network. The malware, called KeyDrift, is designed to copy the keys that encrypt traffic between sites and store them for later use, Cisco Talos said on October 28. Talos calls the attacks historical but does not specify when they
Microsoft has released out-of-band (OOB) Windows updates to remove trust in certificates tied to compromised eMudhra certificate authority keys, protecting systems that do not receive automatic certificate trust updates. [...]
The GoAhead embedded web server loaded a certificate revocation list into its default TLS backend but never turned revocation checking on, so a revoked client certificate could still pass login on affected setups. The flaw is in builds that use the OpenSSL backend with mutual-TLS, where the server checks a client certificate and vice versa, and a revocation list is configured to block revoked
The North Korea-linked Lazarus Group has been attributed to a cyber espionage campaign dubbed Operation FlashHole targeting at least three organizations in South Korea spanning the construction, software, and wire-communication equipment manufacturing sectors. According to Russian cybersecurity company Kaspersky, the campaign has been active since at least July 2025. It's assessed to pick up
OpenAI's compaction feature, which shrinks a long conversation to save space, could be turned into a way to copy a model's hidden reasoning out in plain text, security firm Xint has shown. OpenAI's reasoning models work through a problem before answering, and the service normally returns only the raw reasoning as an encrypted item the user cannot read. The method got past
Cybersecurity researchers have disclosed a Microsoft 365 campaign that has been observed leveraging an adversary-in-the-middle (AitM) relay to capture sign-in sessions and then replay the stolen tokens to break into email accounts at 79 organizations. Huntress, which observed the activity between July 14 and September 22, 2026, said it detected 497 successful Microsoft 365 sign-in events across
eMudhra, an Indian certificate authority (CA), will withdraw from its global SSL/TLS certificate business, its board decided on Thursday. The decision came five days after a researcher reported recovering the private keys of eight of its intermediate CA certificates. eMudhra said it will replace affected customers' certificates with free ones from partners, though its
Platform-as-a-Service (PaaS) provider Railway on Wednesday disclosed "anomalous activity" related to systems that store customer environment variables. Upon further investigation, the company found that an unauthorized third party may have gained access to encrypted environment variables, and, in some cases, obtained the decrypted contents. The impact, it said, is limited to a "subset of users,
North Korean hackers are using a post-quantum cryptographic mechanism to secure malicious payload delivery in new operations that combine old and new malware. [...]
Certificate authority eMudhra revoked eight compromised intermediate certificates after researchers found their private keys were so weak that anyone could recover them almost instantly and use them to forge trusted certificates for legitimate websites. [...]
The private keys of eight eMudhra intermediate certificate authority (CA) certificates are compromised, Mozilla and Google's Chrome Root Program confirms on October 20. An intermediate CA signs the certificates that websites present, so anyone holding one of these keys could issue a certificate for any website that a browser would accept. A researcher reported the
Cybersecurity researchers have released a proof-of-concept (PoC) exploit for a recently patched critical security flaw impacting Fortinet FortiSIEM that could result in arbitrary code execution. The vulnerability, tracked as CVE-2026-106173 (CVSS score: 9.4), is a critical path traversal flaw that could allow an unauthenticated attacker to execute unauthorized code or commands via specially
Go 1.27.3 and Go 1.26.10, released on October 20, make Go's certificate verifier reject any certificate chain that passes through one of eight intermediate certificate authority keys. Programs built on the new release will refuse connections to sites and services whose certificates were issued under those keys. The Go team says the keys belong to one certificate authority it has not
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
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
NGINX released versions 1.30.6 and 1.31.7 on October 14 to fix five vulnerabilities, one of them present in every release since May 2005. There are three memory bugs that F5, the company behind NGINX, says could crash a worker process or possibly let an attacker run code, and each requires a specific configuration to exploit. A fourth lets an attacker forge a TLS session that could
A Saudi National and employee of OpenAI has been arrested for allegedly planting a hidden recording device in an executive conference room at the company's San Francisco offices to covertly record sensitive conversations. Abdulrahman Alfozan, 35, has been charged with using or endeavoring to use an electronic, mechanical, or other device to intercept oral communications. He was arrested by
