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 researcher has found a way to impersonate Microsoft corporate email accounts, which could make phishing attacks harder to spot.
Former employee says software giant dismissed his warnings about a critical flaw because it feared losing government business. Russian hackers later used the weakness to breach the National Nuclear Security Administration, among others.
Morphisec researchers have identified a critical Microsoft Outlook vulnerability, CVE-2024-30103, and detail its technical impact and recommended actions.
Today is Microsoft's June 2024 Patch Tuesday, which includes security updates for 51 flaws, eighteen remote code execution flaws, and one publicly disclosed zero-day vulnerability.

Microsoft's education-focused flavor of its cloud productivity suite, Microsoft 365 Education, is facing investigation in the European Union. Privacy
If Microsoft intended the 2024 Build event to be overshadowed by controversy then it succeeded as calls intensify for the company to rethink its strategy around Recall.
The Windows Recall feature, still in preview, takes a snapshot of a Copilot+ PC user's screen every couple of seconds and then sends it to disk, letting the user scroll the archive of snapshots when looking for something or use an AI system to recall screenshots by text.
I wrote a piece recently about Copilot+ Recall, a new Microsoft Windows 11 feature which — in the words of Microsoft CEO Satya Nadella- takes “screenshots” of your PC constantly, and makes it into an…
In the ever-evolving landscape of cyberthreats, staying ahead of malicious actors is a constant challenge. The latest edition of Cyber Signals dives deep into the world of Storm-0539, also known as Atlas Lion, shedding light on their sophisticated methods of gift and payment card theft.
The Kaspersky GERT has detected a VBS script that has been abusing Microsoft Windows features by modifying the system to lower the defenses and using the local MS BitLocker utility to encrypt entire drives and demand a ransom.
