Existing low-level access for security solutions will undergo a rework
Microsoft observed North Korean threat actor Citrine Sleet exploiting the CVE-2024-7971 zero-day vulnerability in Chromium. Citrine Sleet targets the cryptocurrency sector for financial gain.
A vulnerability in Microsoft Copilot Studio could be exploited to access sensitive information on the internal infrastructure used by the service, Tenable reports.
The flaw, tracked as CVE-2024-38206 (CVSS score of 8.5) and described as a ‘critical’ information disclosure bug, has been fully mitigated, Microsoft said in an August 6 advisory.
An adversary could exploit these vulnerabilities by injecting malicious libraries into Microsoft's applications to gain their entitlements and user-granted permissions.
Microsoft researchers found multiple vulnerabilities in OpenVPN that could lead to an attack chain allowing remote code execution and local privilege escalation. This attack chain could enable attackers to gain full control over targeted endpoints, potentially resulting in data breaches, system compromise, and unauthorized access to sensitive information.
Discover how Iran is allegedly targeting the 2024 US election, the potential impacts, and the measures being taken to safeguard the democratic process.
Researcher showcases hack against Microsoft Windows Update architecture, turning fixed vulnerabilities into zero-days.
Delta CEO Ed Bastian said the company plans to seek compensation from Microsoft and CrowdStrike.
o you have problems configuring Microsoft's Defender? You might not be alone: Microsoft admitted that whatever it's using for its defensive implementation exacerbated yesterday's Azure instability.
No one has blamed the actual product named "Windows Defender," we must note.
According to Microsoft, the initial trigger event for yesterday's outage, which took out great swathes of the web, was a distributed denial-of-service (DDoS) attack. Such attacks are hardly unheard of, and an industry has sprung up around warding them off.
Microsoft confirmed today that a nine-hour outage on Tuesday, which took down and disrupted multiple Microsoft 365 and Azure services worldwide, was triggered by a distributed denial-of-service (DDoS) attack.
Microsoft researchers have uncovered a vulnerability in ESXi hypervisors being exploited by several ransomware operators to obtain full administrative permissions on domain-joined ESXi hypervisors. ESXi is a bare-metal hypervisor that is installed directly onto a physical server and provides direct access and control of underlying resources. ESXi hypervisors host virtual machines that may include critical servers in a network. In a ransomware attack, having full administrative permission on an ESXi hypervisor can mean that the threat actor can encrypt the file system, which may affect the ability of the hosted servers to run and function. It also allows the threat actor to access hosted VMs and possibly to exfiltrate data or move laterally within the network.
In this blog post, we examine the recent CrowdStrike outage and provide a technical overview of the root cause. We also explain why security products use kernel-mode drivers today and the safety measures Windows provides for third-party solutions. In addition, we share how customers and security vendors can better leverage the integrated security capabilities of Windows for increased security and reliability. Lastly, we provide a look into how Windows will enhance extensibility for future security products.
Microsoft has started responding with changes it wants to see in the wake of the CrowdStrike botched update. It looks like Windows kernel access is on the agenda.
On July 18, CrowdStrike, an independent cybersecurity company, released a software update that began impacting IT systems globally. Although this was not a Microsoft incident, given it impacts our ecosystem, we want to provide an update on the steps we’ve taken with CrowdStrike and others to remediate and support our customers.
On patch Tuesday last week, Microsoft released an update for CVE-2024-38112, which they said was being exploited in the wild. We at the Trend Micro Zero Day Initiative (ZDI) agree with them because that’s what we told them back in May when we detected this exploit in the wild and reported it to Microsoft. However, you may notice that no one from Trend or ZDI was acknowledged by Microsoft. This case has become a microcosm of the problems with coordinated vulnerability disclosure (CVD) as vendors push for coordinated disclosure from researchers but rarely practice any coordination regarding the fix. This lack of transparency from vendors often leaves researchers who practice CVD with more questions than answers.
[German]A Microsoft software developer has accidentally shared internal PlayReady source code with the public (a developer forum). The data leak of 4 GByte is sufficient to compile the required DLL from the source code. This could be a real boon for people who want to reverse engineering or crack PlayReady. What is PlayReady? PlayReady is...
A novel command execution technique dubbed 'GrimResource' uses specially crafted MSC (Microsoft Saved Console) and an unpatched Windows XSS flaw to perform code execution via the Microsoft Management Console.
