The ShinyHunters data-theft wave against Oracle PeopleSoft, covered yesterday, now has a confirmed root cause: a zero-day. Oracle has issued an out-of-band emergency mitigation for CVE-2026-35273, a critical flaw (rated 9.8) in PeopleSoft PeopleTools that lets an unauthenticated attacker run code on the server over HTTP, with no login required. Google's Mandiant says the bug was exploited from May 27 to June 9, before any advisory existed, and notified more than 100 affected organizations, 68 percent of them universities. The exposed component is the Environment Management Hub. Affected versions are PeopleTools 8.61 and 8.62; a full patch is still pending.
The critical Ivanti Sentry flaw covered yesterday is now under active attack, with researchers reporting compromised gateways within about 24 hours of the patch and public patch analysis. CVE-2026-10520, rated a perfect 10, is an OS command injection in an internal configuration API that accepts commands from anyone who can reach it over the internet, granting remote code execution as root with no login. A second flaw, CVE-2026-10523, lets attackers create their own admin accounts. With exploitation confirmed and detection tooling public, the time to patch has effectively run out for internet-exposed appliances. Ivanti released fixes earlier this week.
The researcher known as Nightmare Eclipse has published a second unpatched Windows exploit in two days, this one defeating BitLocker disk encryption. Called GreatXML, it abuses the Windows Defender Offline Scan feature: any machine that has ever run an offline scan is left permanently vulnerable. An attacker with physical access copies a crafted unattend.xml file and a Recovery folder to the recovery partition, reboots into the Windows Recovery Environment with Shift plus Restart, and gets a privileged shell with full access to the encrypted drive, no login needed. Proof-of-concept code is public on GitHub, there is no patch yet, and Microsoft says it is investigating.
The Gentlemen, a ransomware-as-a-service operation tracked by Microsoft as Storm-2697, has been upgraded with a self-spreading mode and now claims 478 victims across dozens of countries and industries. Written in Go and obfuscated to evade analysis, its optional --spread switch turns a single-machine infection into a network worm that deploys the encryptor to every reachable system, using stolen or reused credentials to move laterally. A --wipe switch destroys recoverable data and forensic traces. On each host it disables Defender, weakens firewall and authentication settings, and adds scheduled tasks for persistence. Initial access often comes through compromised Fortinet edge-device credentials.
Kyushu Electric Power, one of Japan's largest utilities, has disclosed a physical security incident: a storage drive containing the personal data of more than 10.9 million customers went missing. Because the exposure stems from lost media rather than a network intrusion, the risk depends largely on whether the drive was encrypted, a detail that determines if the data is readable by whoever finds it. The incident is a reminder that data-governance failures, like unencrypted or poorly tracked portable storage, can expose as many records as a sophisticated hack. Affected customers should watch for fraud and phishing attempts referencing their utility account.
Fortinet has patched a critical flaw in FortiSandbox, the appliance that detonates suspicious files and feeds malware verdicts to the rest of a Fortinet security deployment. The bug (CVE-2026-25089, rated 9.8) is an OS command injection in the web interface that lets a remote, unauthenticated attacker run arbitrary commands by sending crafted HTTP requests. Compromising a sandbox is especially dangerous because attackers can both pivot deeper into the network and blind the very system meant to catch malware. Fixed versions are FortiSandbox 5.0.6 and 4.4.9, with matching updates for the Cloud and PaaS editions.
In an unusual misinformation campaign, fraudulent data-breach notices were submitted to Maine's official Attorney General breach portal and published before anyone verified them, forcing named companies to issue denials. One filing falsely claimed a Discord breach affecting more than 10 million people, submitted not by a company representative but by an individual using a personal Gmail address, a placeholder phone number, and impossible dates. Because the portal is public and a listing does not mean a breach is confirmed, the fakes can spread fear, damage reputations, and seed convincing phishing lures. It highlights how trusted disclosure channels can be weaponized.
Researchers at BlackFog have detailed OnyxC2, a new malware-as-a-service sold on cybercrime forums that packages professional-grade data theft for as little as $250 a month, with a $500 premium tier adding hidden-desktop control and a $6,000 buyout option. It ships with a polished control panel and ready-made lures disguised as FinePrint, Windows Settings, a fake Windows update, and a game installer. Its payloads slipped past VirusTotal scanning when first uploaded and were still undetected weeks later, and builds use AES-256 encryption. The low price and turnkey design lower the barrier for less-skilled criminals to run capable infostealing campaigns.
VulnCheck reports that attackers are actively exploiting an unpatched flaw in Langflow, a popular open-source platform for building AI applications. The bug (CVE-2026-5027, rated 8.8) is a path-traversal weakness: the file-upload endpoint does not clean the supplied filename, so an attacker can use directory-climbing sequences to write files anywhere on the server, a foothold that leads to remote code execution. Tenable, which found it, says the maintainers did not respond after three contact attempts in early 2026, and there is still no official fix. Early exploitation appears to be probing, with attackers writing harmless test files, but that usually precedes heavier attacks.
Microsoft has shipped the first full patch for an Exchange Server zero-day that attackers have been exploiting since May. The flaw (CVE-2026-42897) is a cross-site scripting bug in Outlook Web Access: an attacker emails a victim, and when the message is opened in OWA, malicious JavaScript runs inside the victim's authenticated session, allowing session-token theft and mailbox impersonation without ever touching the server. It affects Exchange Server 2016, 2019, and Subscription Edition, and CISA added it to its known-exploited list back in May. Until this week only temporary mitigations existed; the June security updates provide the permanent fix.
