Hackers Disable Endpoint Protection and Deploy Sliver Across Compromised Windows Domain

The Hunter's Ledger tracked campaign UTA-2026-024 using Sliver C2, Domain Admin account creation, and Ethereum-based C2 rotation to compromise a US organization's Windows domain.

The Hunter's Ledger tracked an intrusion at one unnamed US organization as UTA-2026-024, staged from exposed server 193.233.202.17 with a Sliver beacon. Operators created a non-expiring Domain Admin account, enabled RDP with NLA disabled, dumped SAM, SYSTEM and SECURITY hives plus LSASS memory, and disabled eight endpoint protection services. A Node.js implant resolved its C2 server from an Ethereum smart contract that rotated domains five times in five months, while SYSTEM scheduled tasks with backdated dates and DNS allowlist manipulation provided persistence. The infrastructure ties to a confirmed ransomware incident, but no encryptor deployment was proven in this intrusion.

ownCloud Flaw Exploited to Steal Nuclear Records From Philippine Research Body

A Chinese-speaking actor exploited ownCloud CVE-2023-49105 to steal 176 nuclear research files from Philippine organizations, prompting CISA to add the flaw to KEV.

CISA added CVE-2023-49105 (CVSS 9.8), an ownCloud WebDAV API authentication bypass fixed in version 10.13.1, to the KEV catalog after Hunt.io found an open directory hosting custom Python exploit scripts and tools including Sliver, Metasploit, and Mettle. The actor downloaded 176 files (~372 MB) from a Philippine nuclear research body, including nuclear-material account records, 2023-2028 strategic plans, BitLocker keys, and a KeePass database; a second intrusion exploited LiteSpeed Cache CVE-2024-28000 at a shipbuilding firm serving the Philippine Navy, with XML-RPC brute-force and an EtherHiding/ClickFix component. FCEB agencies must patch by August 30, 2026. CISA also added Linux Kernel CVE-2026-53362 and Artifactory CVE-2026-66384 after OpenAI said its AI agents exploited them against internal infrastructure.

Nearly 800 Malicious npm Packages Deliver Cross

Nearly 800 typo-squatted npm packages deliver WEL1DROPPER, a cross-platform downloader installing RAT and infostealer payloads on Windows, macOS, Linux.

Researchers found roughly 800 npm packages with AI-generated typo-squat names that trigger a WEL1DROPPER downloader when loaded via require() rather than install hooks. The downloader fetches payloads from Cloudflare Workers hosts, falling back to DNS TXT records from wel1.ru, then achieves persistence, sandbox checks, ETW/AMSI patching and Sliver C2 deployment on Linux. Domains like tcsbank.ru suggest targeting of Russian financial institutions; Sonatype tracks the campaign as Flooding Dropper, a possible evolution of the Moika dependency-confusion campaign. Unit 42 separately documented npm/PyPI crypto stealers and malicious Chrome extensions that turn browsers into residential proxy crawlers.

    Improper Authentication in ownCloud Server Allows Unauthenticated File Access
    ownCloud Server versions from 10.6.0 up to (but not including) 10.13.1 accept WebDAV pre-signed URLs even when no signing key is configured for the file owner, an improper authentication flaw (CWE-287). A remote attacker who knows a victim's username can therefore access, modify, or delete that user's files without any credentials, with no privileges or user interaction required (CVSS 9.8). Any organization running a self-hosted ownCloud Server instance in the affected version range is exposed, especially internet-facing deployments. CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-08-27, confirming exploitation in the wild, and EPSS assigns a 43.2% probability of exploitation within 30 days (99th percentile). No public proof-of-concept code is known, but recent press reports of attacks against ownCloud (including theft of records at a Philippine research body) indicate active targeting of ownCloud flaws.

    Out-of-Bounds Write in Linux Kernel IPv6 Stack via UDPv6 MSG_SPLICE_PAGES
    CVE-2026-53362 is an out-of-bounds write (CWE-787) in the Linux kernel's IPv6 output path: __ip6_append_data() mis-accounts fraggap bytes on the paged-allocation branch, leaving the new skb's linear area undersized so the copy of carried-over fragment-gap data spills past skb->end into the trailing skb_shared_info. An unprivileged local user can trigger the corruption by sending over a UDPv6 socket using MSG_MORE combined with MSG_SPLICE_PAGES; the bad accounting was introduced by commit 773ba4fe9104 ('ipv6: avoid partial copy for zc') and became triggerable when commit ce650a166335 allowed the MSG_SPLICE_PAGES case to proceed instead of returning -EINVAL. Successful triggering causes kernel memory corruption that, per the high confidentiality/integrity/availability scores, can lead to loss of data confidentiality, integrity and availability — potentially local privilege escalation or a system crash. Any Linux system running a kernel with the affected code is exposed; the source data provides no specific affected version numbers, only the introducing and trigger commits. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-08-27, indicating known in-the-wild exploitation (ransomware use unknown), with EPSS at 0.5% and no public PoC known.

    Authenticated Path Traversal Write in JFrog Artifactory Exploited in the Wild
    CVE-2026-66384 is a directory/path-restriction bypass (CWE-22) in JFrog Artifactory in which an authenticated user can write data outside the intended Docker cache path when specific remote-repository conditions are met. The attack is carried out over the network using valid low-privilege credentials and requires no user interaction, but the triggering conditions are specific enough that the CVSS vector rates exploit complexity as high. A successful attacker gains unauthorized modification of files outside the cache directory (integrity impact only per the CVSS vector, with no confidentiality or availability impact scored), potentially tampering with stored content or system files depending on the deployment. Any organization running JFrog Artifactory with Docker remote repositories is potentially affected. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-08-27, confirming exploitation in the wild; no public proof-of-concept is known and ransomware use is not confirmed.
