Hacker Discloses Unpatched Windows Zero-Day Vulnerability (With PoC)

Hacker Discloses Unpatched Windows Zero-Day Vulnerability (With PoC)

Aug 28, 2018
A security researcher has publicly disclosed the details of a previously unknown zero-day vulnerability in the Microsoft's Windows operating system that could help a local user or malicious program obtain system privileges on the targeted machine. And guess what? The zero-day flaw has been confirmed working on a "fully-patched 64-bit Windows 10 system." The vulnerability is a privilege escalation issue which resides in the Windows' task scheduler program and occured due to errors in the handling of Advanced Local Procedure Call (ALPC) systems. Advanced local procedure call (ALPC) is an internal mechanism, available only to Windows operating system components, that facilitates high-speed and secure data transfer between one or more processes in the user mode. The revelation of the Windows zero-day came earlier today from a Twitter user with online alias SandboxEscaper, who also posted a link to a Github page hosting a proof-of-concept (PoC) exploit for the ...
Hacker Reveals Easiest Way to Hijack Privileged Windows User Session Without Password

Hacker Reveals Easiest Way to Hijack Privileged Windows User Session Without Password

Mar 20, 2017
You may be aware of the fact that a local Windows user with system rights and permissions can reset the password for other users, but did you know that a local user can also hijack other users' session, including domain admin/system user, without knowing their passwords? Alexander Korznikov, an Israeli security researcher, has recently demonstrated that a local privileged user can even hijack the session of any logged-in Windows user who has higher privileges without knowing that user's password, using built-in command line tools. This trick works on almost all versions of Windows operating system and does not require any special privileges. Korznikov is himself unable to figure out if it is a Windows feature or a security flaw. The issue discovered by Korznikov is not entirely new, as a French security researcher, namely Benjamin Delpy, detailed a similar user session hijacking technique on his blog some six years ago. Korznikov calls the attack a "privilege ...
How AI Is Transforming IAM and Identity Security

How AI Is Transforming IAM and Identity Security

Nov 15, 2024Machine Learning / Identity Security
In recent years, artificial intelligence (AI) has begun revolutionizing Identity Access Management (IAM), reshaping how cybersecurity is approached in this crucial field. Leveraging AI in IAM is about tapping into its analytical capabilities to monitor access patterns and identify anomalies that could signal a potential security breach. The focus has expanded beyond merely managing human identities — now, autonomous systems, APIs, and connected devices also fall within the realm of AI-driven IAM, creating a dynamic security ecosystem that adapts and evolves in response to sophisticated cyber threats. The Role of AI and Machine Learning in IAM AI and machine learning (ML) are creating a more robust, proactive IAM system that continuously learns from the environment to enhance security. Let's explore how AI impacts key IAM components: Intelligent Monitoring and Anomaly Detection AI enables continuous monitoring of both human and non-human identities , including APIs, service acc...
Hackers Selling Unpatched Microsoft Windows Zero-Day Exploit for $90,000

Hackers Selling Unpatched Microsoft Windows Zero-Day Exploit for $90,000

Jun 03, 2016
How much a Windows zero-day exploit that affects all versions of Windows operating system costs on the black market? It's $95,000, at least, for the one recently spotted by security researchers. Researchers from Trustwave's SpiderLabs team have uncovered a zero-day exploit on Russian underground malware forum exploit.in, affecting all versions of Microsoft Windows OS from Windows 2000 all the way up to a fully patched version of Windows 10. The zero-day exploit for the previously unknown vulnerability in " every version " of Windows is openly sold for $90,000 ( over £62,000 ). The security team originally discovered the zero-day exploit last month when the firm saw its ad on a Russian hacking forum for $95,000. However, the price has now been dropped to $90,000. The zero-day vulnerability in question claims to be a Local Privilege Escalation (LPE) bug in Windows that offers admin access to run malicious code on a victim's PC and is less dangerous th...

Ransom32 — First JavaScript-powered Ransomware affecting Windows, Mac and Linux

Ransom32 — First JavaScript-powered Ransomware affecting Windows, Mac and Linux

Jan 04, 2016
Here's New Year's first Ransomware: Ransom32 . A new Ransomware-as-a-service, dubbed Ransom32 , has been spotted that for the first time uses a ransomware written in JavaScript to infect Mac, Windows as well as Linux machines. Ransom32 allows its operators to deploy the malware very quickly and easily. It has a dashboard that enables operators to designate their Bitcoin addresses to which the ransom can be sent. The dashboard also shows stats about how much Bitcoins they have made. In short, this new ransomware-as-a-service is so simple, and efficient at the same time, that anyone can download and distribute his/her own copy of the ransomware executable as long as he/she have a Bitcoin address. The copy of Ransom32 was first analysed by Emsisoft, which found that the new ransomware family, which embedded in a self-extracting WinRAR archive, is using the NW.js platform for infiltrating the victims' computers, and then holding their files by encrypting the...
Patch Report: All Versions of Windows affected by Critical Vulnerability

Patch Report: All Versions of Windows affected by Critical Vulnerability

Oct 14, 2015
Microsoft has rolled out six security updates this Patch Tuesday , out of which three are considered to be " critical, " while the rest are marked as " important. " Bulletin MS15-106 is considered to be critical for Internet Explorer (IE) and affects absolutely all versions of Windows operating system. The update addresses a flaw in the way IE handles objects in memory. The flaw could be exploited to gain access to an affected system, allowing hackers to gain the same access rights as the logged-in user. A hacker could " take advantage of compromised websites, and websites that accept or host user-provided content or advertisements ," the advisory states. " These websites could contain specially crafted content that could exploit the vulnerabilities. " Therefore, the dependency here is that an IE user must knowingly click on the malicious link, which then be leveraged by an attacker to get the full control over a computer t...
