A phishing campaign is impersonating more than 30 well-known brands, including Adobe, Netflix, Coca-Cola, and OpenAI, in fake job-interview lures aimed at marketing professionals, with the goal of stealing their Google account credentials. Posing as recruiters from desirable companies, the attackers draw targets into a process that leads to a convincing Google sign-in page under their control. Because marketers often manage valuable brand, advertising, and analytics accounts tied to Google, a stolen login can open the door to ad fraud, data access, and further impersonation. The lure works by exploiting excitement about a career opportunity to lower the target's guard.
A use-after-free flaw in Linux's KVM hypervisor, nicknamed Januscape and hidden in the code for about 16 years, lets a virtual machine attack the physical host it runs on. Tracked as CVE-2026-53359, it sits in the shadow memory code that KVM uses on both Intel and AMD systems when nested virtualization is enabled. From inside a guest with root, an attacker can corrupt host kernel memory: the public proof-of-concept crashes the entire host, taking down every other tenant on that machine, and the researcher says a private exploit can run code as root on the host. The fix reached mainline Linux in June, and distributions are shipping updated kernels now.
Attackers have started probing a critical flaw in Gitea's official Docker images, the self-hosted Git service used by many development teams. The images shipped a configuration that trusted the X-WEBAUTH-USER header from any source address, so with reverse-proxy login enabled, anyone who could reach the port could send that header and be authenticated as any user, no password required. Tracked as CVE-2026-20896 and rated 9.8, it was fixed in version 1.26.3 late last month, which removes the wildcard and makes reverse-proxy authentication opt-in. Sysdig reported the first exploitation attempt 13 days after disclosure, so far just reconnaissance, against some of the roughly 6,200 internet-facing Gitea instances.
One of the critical ColdFusion vulnerabilities Adobe patched last week is now being exploited in the wild. The flaw, CVE-2026-48282, is a path-traversal issue rated 10.0 that lets an attacker run arbitrary code on a ColdFusion server, and it was among seven top-severity bugs Adobe fixed in ColdFusion 2025 and 2023. Adobe had flagged the update as high priority given ColdFusion's history as an attacker and ransomware target, and exploitation has followed quickly. Organizations that had not yet applied the update are now in an active-threat window, especially any ColdFusion servers reachable from the internet, which are the most exposed to opportunistic attacks.
Researchers at the Hong Kong University of Science and Technology showed that the static scanners meant to vet add-on "skills" for AI coding agents like Claude Code can be fooled while the malware keeps working. Their technique, SkillCloak, either rewrites the tell-tale bytes a scanner looks for, using look-alike characters and line breaks, or hides the whole payload in a directory scanners skip, such as .git, behind a decoder that rebuilds it only when the agent runs the skill. Across eight scanners and 1,613 real malicious skills, the packing trick evaded detection more than 90 percent of the time. The researchers argue static scanning is not enough and released a runtime checker.
Zscaler found attackers using search-engine poisoning and hidden instructions on malicious websites to manipulate AI agents into making cryptocurrency payments. In one case, a hidden element on the page tells an AI agent that it must "resolve an error" by completing a payment, alongside code that starts a crypto transfer to a hardcoded wallet; the same page also shows human visitors ordinary payment options. Another campaign typosquats a decentralized-finance portfolio tracker and uses hidden prompts to convince agents the fake site is the real one. The attacker is seeding the scheme through several GitHub repositories, showing how autonomous agents that browse and act can be steered by content they read.
LevelBlue detailed QuimaRAT, a new Java-based remote access trojan sold as a service that runs across Windows, Linux, and macOS from the same codebase. Subscriptions range from about $150 for a month to $1,200 for lifetime access, lowering the bar for attackers to get cross-platform reach. Built around a modular design, it expands its capabilities through encrypted plugins that operators can load, update, or remove from their command server on the fly. It also uses several obfuscation techniques to keep changing how it looks to security tools without altering its behavior, so signatures based on its appearance are likely to go stale quickly.
Researchers found a flaw in Opera GX, the gaming-focused version of the Opera browser, that let a malicious website silently install a browser add-on, known as a mod, and use it to pull specific data from the pages the victim later visited. In a proof of concept, they reconstructed a signed-in user's full Gmail address from a single visit, with no clicks required. The issue stemmed from how the browser handled automatic mod installation, giving a hostile page more power than it should have. Opera has patched the flaw and says it found no evidence of exploitation before the fix, but users should update.
Arctic Wolf detailed how affiliates of the Anubis ransomware group break in and stay hidden, drawing on intrusions across healthcare, finance, and manufacturing this year. Initial access came from stolen VPN credentials and from exploiting CitrixBleed 2, a NetScaler flaw that leaks session tokens from memory and lets attackers bypass multi-factor authentication. Once inside, the affiliates leaned on legitimate remote-management software such as ScreenConnect, Zoho Assist, and MeshAgent to blend in with normal IT activity, moving through networks with RDP and PsExec toward domain controllers, backups, and storage devices. They stole data using common cloud-transfer tools before encrypting anything, which is exactly where defenders have the best chance to catch them.
Medtronic has begun notifying about 3.8 million people that their data was exposed in the breach of its corporate IT systems earlier this year, giving a concrete scale to the ShinyHunters attack it first disclosed in April. The exposed information includes names, contact details, dates of birth, Social Security numbers, and health-related data, a more sensitive set than the company initially detailed. The intrusion, which the extortion group claimed involved around nine million records, was limited to corporate systems, with Medtronic saying its products, patient safety, and device networks were not affected. Affected individuals are being offered credit monitoring, and several class-action lawsuits have followed.
