A security researcher using the "Nightmare Eclipse" handle has released a Windows zero-day exploit dubbed LegacyHive that allows attackers to escalate privileges on up-to-date Windows systems. [...]
LegacyHive Is a Local Privilege Escalation BugThe vulnerability hunter in a feud with Microsoft released yet another Windows zero-day Tuesday as promised, though the touted "bone-shattering" disclosure was stripped down to prevent public exploitation. LegacyHive, exploits a profile-loading race condition to access another user's registry hive.
Researchers said the vulnerabilities, which attackers are chaining together, were first exploited three weeks before the vendor disclosed and patched the defects. The post SonicWall customers under threat as attackers exploit 2 zero-days appeared first on CyberScoop.
LegacyHive PoC exposes a Windows Privilege Escalation flaw affecting fully patched Windows desktop and server systems. Just hours after Microsoft’s July 2026 Patch Tuesday, security researcher Nightmare Eclipse, also known as Chaotic Eclipse, published a new Windows zero-day proof-of-concept called LegacyHive. This time, the target is the Windows User Profile Service (ProfSvc), and unlike the […]
Security researcher Chaotic Eclipse (aka Nightmare-Eclipse) has released a new proof-of-concept (PoC) exploit called LegacyHive
SonicWall has warned of active exploitation of two zero-day vulnerabilities impacting Secure Mobile Access (SMA) 1000 series appliances, one of which could be exploited to achieve arbitrary command execution
The researcher known as "Nightmare-Eclipse" published a proof-of-concept (PoC) exploit for the Windows Defender vulnerability in early June after dropping several other Microsoft zero-days.
Weeks after the exploit code dropped, Redmond has finally ships a fix for the Defender zero-day
Infosecurity spoke with the researcher who dumped over 30 proof-of-concept exploits without disclosing the vulnerabilities first
Mandiant detailed the incident in a blog post Wednesday, but it’s unclear who was behind it or if they managed to get broad visibility into the victim’s internal traffic. The post Malicious hackers exploit Cisco zero-day for highest access level at communications service provider appeared first on CyberScoop.
Breaches don't always start with a zero-day. An exposed admin panel can get brute-forced, or credentials reused from a previous attack. But when a vulnerability does drop — like MongoBleed earlier this year, which let attackers pull credentials and session tokens from server memory without authentication — anything internet-facing is immediately at risk
Stuff broke again. Not in a movie way. An old tool was left exposed. An abandoned package was abused. A deprecated feature was still running in prod
The ShinyHunters extortion crew exploited an unpatched flaw in Oracle PeopleSoft to break into enterprise systems, steal data, and demand payment to keep it private. The campaign hit universities hardest
Another day, another Windows exploit code
GreatXML bypasses BitLocker via Defender offline scan artifacts, giving SYSTEM shell in Recovery Mode. No patch exists. Any machine that ran an offline scan is vulnerable. On June 10, security researcher Chaotic Eclipse (aka Nightmare Eclipse) published a new working exploit dubbed GreatXML that bypasses BitLocker and opens a command shell with full SYSTEM privileges […]
The researcher Chaotic Eclipse released a PoC for the RoguePlanet Microsoft Defender zero-day, which can grant SYSTEM privileges on fully patched Windows systems. Security researcher Chaotic Eclipse, also known as Nightmare-Eclipse, has published a new proof-of-concept exploit for a RoguePlanet Microsoft Defender zero-day. The flaw relies on a race condition that can provide attackers with […]
The anonymous security researcher going by the name Chaotic Eclipse (aka Nightmare-Eclipse) has released a proof-of-concept (PoC) exploit for yet another Microsoft Defender zero-day named RoguePlanet
A security researcher has released a new Microsoft Defender zero-day exploit named "RoguePlanet" just hours after Microsoft fixed two previously disclosed flaws during June 2026 Patch Tuesday. [...]
A researcher publicly released a VS Code exploit within hours, citing past disputes with Microsoft over bug handling. The security researcher Ammar Askar found a new serious zero-day in Visual Studio Code, told a contact at GitHub about it, and published a working exploit one hour later. “Just by clicking a link, it’s possible for […]
Assume the breach. Zero-days keep shipping, AI is writing exploits faster than anyone patches, and "patch everything in time" stopped working years ago. Stop betting the org on winning that race. You don't control which bug lands. You control what it can reach once it does
