Microsoft announced last year of extended support for Windows 7

Published

on

Microsoft announced that it will end support for Windows 7 for all users on January 10, 2023.

Windows 7 has long since expired and is not receiving security updates, but Microsoft continues to release critical patches through its Extended Security Update (ESU) program.

Available only to companies still using Windows 7, these updates can only be installed by paid customers, and the cost of an ESU subscription increases over time.

On February 8, 2022, Windows 7 will enter the third and final year of ESU, after which Microsoft will finally stop supporting the OS for all users.

Microsoft reported that on January 10, 2023, Windows 7 will permanently shut down, so devices still running Windows 7 will need to be updated to continue receiving updates.

The company also announced that Windows Server 200 SP2 will receive another additional year of support, and users will be able to receive ESU updates through January 2024.

“For Windows Server 2008 R2 SP1, Windows Server 2008 SP2, Windows Server 2008 R2 SP1 for Embedded Systems and Windows Server 2008 SP2 for Embedded Systems running on Microsoft Azure, ESU will receive an additional year of extended support starting February 14, 2023 and ending January 9, 2024, “Microsoft said.

Upgrading to newer versions of Windows is slowly but surely becoming the only solution, although upgrading to Windows 10 or Windows 11 will mean new hardware costs for many.

Vulnerability found in the Apple M1 processor that cannot be

Specialists from the Computer Science and Artificial Intelligence Laboratory (CSAIL) from the Massachusetts Institute of Technology said that they were able to develop a PACMAN attack technique, which is possible due to a hardware vulnerability in the Apple M1 processor. Moreover, it cannot be closed by software.

The attack itself is carried out using software and hardware, and it can be performed remotely. The PACMAN attack makes it possible to gain access to the kernel of the operating system. At the same time, potentially the same vulnerabilities can be in Qualcomm and Samsung processors, but this has not yet been confirmed.

The technical side of the attack is based on the Pointer Authentication function. It is used to check Pointer Authentication Codes (PACs), allowing only code-signed software to run. However, the PACMAN method allows you to select the necessary PAC values. In part, this technique is similar to Specter and Meltdown in Intel processors.

At the same time, Apple spokesman Scott Radcliffe said that the vulnerability does not pose an immediate threat to users and is not sufficient in itself to bypass operating system protections.

A few years ago, a vulnerability was already found in Arm processors that allows an attacker to gain unauthorized access to data.

So much for Unisoc Companies have discovered a vulnerability in

Unisoc is actively capturing the market for single-chip systems, although it does so exclusively in the budget segment itself. However, it turned out that these platforms have a critical vulnerability.

So much for Unisoc.  Companies have discovered a vulnerability in single-chip systems

According to the source, the problem is in the modem’s firmware and affects both 4G and 5G platforms. The vulnerability, numbered CVE-2022-20210, was discovered while scanning Non-Access Stratum (NAS) message handlers. This vulnerability could be used to neutralize or block the device’s cellular capabilities.

The vulnerability was first discovered in the Motorola Moto G20 smartphone based on the Unisoc T700 SoC. But in the end it turned out that the same vulnerability occurs in other platforms, however, the source did not provide a list.

The Check Point specialists who discovered the vulnerability notified Unisoc back in May, and the company has already released a fix, so smartphone owners should not worry now if they update the software of their devices.

New vulnerability in Microsoft Office is heavily exploited by hackers

A serious vulnerability has been found in the Microsoft Office suite that could potentially allow attackers to execute arbitrary code.

New vulnerability in Microsoft Office is heavily exploited by hackers

She was assigned the number CVE-2022-30190, and among the researchers they gave the name Follina. As noted in Kaspersky Lab, the most unpleasant thing is that there is no fix yet, and in the meantime, the vulnerability is already being actively exploited by attackers. Vulnerability CVE-2022-30190 threatens all operating systems of the Windows family, both regular and server.

While the update is being developed, experts recommend that all Windows users and administrators take advantage of temporary workarounds. As a Microsoft workaround recommends disable the MSDT URL protocol.

The CVE-2022-30190 vulnerability itself is contained in the Microsoft Windows Support Diagnostic Tool (MSDT), but due to the implementation of this tool, a single malicious office document is enough to exploit the vulnerability.

The scheme could be like this. Attackers create a malicious office document and slip it to the victim, for example by sending an email with an attachment. The infected file contains a link to an HTML file that contains JavaScript code that executes malicious code on the command line via MSDT. As a result, attackers are able to install programs, view, modify or destroy data, as well as create new accounts – that is, do everything that the privileges of the user who opened the infected file allow.
