This week starts small

Monday opens with a trust problem. A mail server flaw is under active use. A network control system was targeted. Trusted packages were poisoned. A fake model page pushed a stealer. Then came the familiar ransom claim: the data was returned and deleted

Chaotic Eclipse, the security researcher behind the recently disclosed Windows flaws, YellowKey and GreenPlasma, has released a proof-of-concept (PoC) for a Windows privilege escalation zero-day flaw that grants attackers SYSTEM privileges on fully patched Windows systems

Not every cloud breach starts with malware or a zero-day. In this incident, attackers discovered an exposed Spring Boot Actuator endpoint, harvested credentials from leaked configuration data, then used the OAuth2 Resource Owner Password Credentials (ROPC) flow to authenticate without MFA.

This week is not about one big event. It shows where things are moving. Network systems, cloud setups, AI tools, and common apps are all being pushed in different ways. Small gaps in access control, exposed keys, and normal features are being used as entry points

This week’s recap shows how small gaps are turning into big entry points. Not always through new exploits, often through tools, add-ons, cloud setups, or workflows that people already trust and rarely question

Mitigation: SSO Access Restricted After Attackers Compromised Fully Patched DevicesNetwork security giant Fortinet locked out cloud customers from its single sign-on service until they update device firmware with a patch against active attacks exploiting an improper access control zero day. Only Fortinet devices running the latest, patched firmware versions can use Fortinet SSO.

A newly patched security flaw impacting Broadcom VMware Tools and VMware Aria Operations has been exploited in the wild as a zero-day since mid-October 2024 by a threat actor called UNC5174, according to NVISO Labs

Cybersecurity never stops—and neither do hackers. While you wrapped up last week, new attacks were already underway

Cybersecurity researchers are calling attention to malicious activity orchestrated by a China-nexus cyber espionage group known as Murky Panda that involves abusing trusted relationships in the cloud to breach enterprise networks

Two critical vulnerabilities affect the security vendor's management console, one of which is under active exploitation. The company has updated cloud-based products but won't have a patch for its on-premises version until mid-August.

The French cybersecurity agency on Tuesday revealed that a number of entities spanning governmental, telecommunications, media, finance, and transport sectors in the country were impacted by a malicious campaign undertaken by a Chinese hacking group by weaponizing several zero-day vulnerabilities in Ivanti Cloud Services Appliance (CSA) devices

Cyberbaddies are coming for your M365 creds, US infosec agency warns The Cybersecurity and Infrastructure Security Agency (CISA) is warning that SaaS companies are under fire from criminals on the prowl for cloud apps with weak security.…

Google Cloud's Hultquist on How State Hackers Exploit Code and Corporate HiringJohn Hultquist, chief analyst at Google Threat Intelligence Group, Google Cloud, discussed how China and North Korea are transforming cyberattacks into organized, factory-like operations. Alongside zero-day exploits, North Korean IT operatives are quietly infiltrating Fortune 500 companies under false identities.

Every week, someone somewhere slips up—and threat actors slip in. A misconfigured setting, an overlooked vulnerability, or a too-convenient cloud tool becomes the perfect entry point. But what happens when the hunters become the hunted? Or when old malware resurfaces with new tricks? Step behind the curtain with us this week as we explore breaches born from routine oversights—and the unexpected

A threat actor posted data on Breachforums from an alleged supply-chain attack that affected more than 140K tenants, claiming to have compromised the cloud via a zero-day flaw in WebLogic, researchers say.

They're good at zero-day exploits, too Silk Typhoon, the Chinese government crew believed to be behind the December US Treasury intrusions, has been abusing stolen API keys and cloud credentials in ongoing attacks targeting IT companies and state and local government agencies since late 2024, according to Microsoft Threat Intelligence.…

Vulnerabilities Can Apparently Be Chained Together to Execute a Hypervisor EscapeBroadcom's VMware cloud infrastructure software division has issued updates to patch three actively exploited zero-day vulnerabilities in all supported versions of its ESXi hypervisor operating system, which can be used to escape from the hypervisor, in what's also known as a virtual machine escape.

Cloud software firm VMware has issued a critical security advisory, detailing three zero-day vulnerabilities being actively exploited in the wild

Suspected nation-state actors are spotted stringing together three different zero-days in the Ivanti Cloud Services Application to gain persistent access to a targeted system.
