Certo Software warns that the capability, designed for convenience, can easily be used to spy on online activity. The post Security researchers find stalkers abusing Chrome’s sync feature appeared first on CyberScoop.

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.

Researchers at Jamf Threat Labs detail CrashStealer, which steals passwords, cryptocurrency wallets and more

Old Unix Symlink Trick Lets Malicious Code Bypass User ChecksWiz researchers found that six popular AI coding assistants can be tricked into modifying sensitive files, including SSH keys, while their approval prompts display a harmless filename. The GhostApproval technique exploits a decades-old Unix symlink behavior to mislead users.

Researchers at the AI Now Institute developed a proof-of-concept exploit showing common AI tools used for security could backfire

A China-linked threat cluster has been exploiting vulnerable Roundcube servers at U.S. and Canadian universities to steal credentials and deploy backdoor malware. [...]

Proofpoint researchers said attackers targeted physics and engineering departments, and warn that the campaign is likely ongoing. The post Suspected Chinese espionage group used a Roundcube exploit chain to burrow into universities appeared first on CyberScoop.

Attackers wasted little time targeting the latest memory disclosure flaw in Citrix's NetScaler products, after researchers published a proof-of-concept exploit (PoC).

Security firm Sysdig says it has found what it believes is the first ransomware attack run from start to finish by an AI agent

Attackers are hiding a data-stealing trojan inside fake exploit code aimed at the people who hunt bugs for a living. The malware, called ChocoPoC, travels in Python proof-of-concept (PoC) repositories on GitHub that claim to exploit hot new CVEs

RustDuck is a small, evolving DDoS botnet migrating to Rust. It uses advanced encryption, anti-analysis evasion, and exploits known IoT flaws. Since February 2026, researchers at QiAnXin’s XLab have been tracking a new malware family, called RustDuck, that hijacks routers, cameras, Android set-top boxes, and exposed servers, then uses them to flood targets with junk […]

DirtyClone: a Linux kernel privilege escalation that silently rewrites executables in memory, leaving no disk trace. Patch now. JFrog Security Research published a working exploit walkthrough on June 25 for CVE-2026-43503 (CVSS score of 8.8), a Linux kernel privilege escalation they call DirtyClone. It’s the fourth vulnerability in the DirtyFrag family, all sharing the same […]

DirtyClone is a new Linux kernel privilege escalation in the DirtyFrag family. JFrog Security Research published a working exploit walkthrough for the flaw on June 25, the first public demonstration for this variant

Security researchers at Paradigm Shift have published a working exploit, dubbed usbliter8, that achieves arbitrary code execution inside the SecureROM of Apple's A12 and A13 chips

Owners of affected iPhones can stop checking for patches now: the fix for this SecureROM bug comes in a new handset

Microsoft researchers have detailed an exploit chain, named AutoJack, that turns an AI browsing agent into a delivery vehicle for remote code execution

AutoJack is a novel exploit chain showing how a single malicious webpage can turn an AI browsing agent into a remote code execution vector on the host machine. By abusing trust in localhost, missing authentication, and unsafe parameter handling, attackers can trigger arbitrary process execution through AutoGen Studio’s MCP WebSocket. The research highlights a broader pattern - when agents can browse untrusted content and access local services, traditional boundaries like localhost are no longer secure. The post AutoJack: How a single page can RCE the host running your AI agent  appeared first on Microsoft Security Blog.

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 […]

Security researchers have published a detailed, working exploit for a Linux kernel use-after-free that lets an unprivileged local user escalate to root and break out of a container

Gamaredon exploits a WinRAR flaw to drop modular, nearly fileless malware on Ukrainian targets, hiding payloads in Windows streams and resolving C2s via Telegram. Sekoia’s Threat Detection & Research team dropped a YARA rule in late December 2025 to hunt for new initial access vectors, and by January 2026 it had already generated a dozen […]
