Cloudflare neutralized powerful multi-vector DDoS attack

Published

The power of the cyberattack has reached almost 2 Tbit / s.

Cloudflare specialists neutralized a multi-vector distributed denial of service (DDoS) attack with a maximum capacity of almost 2 Tbps.

The attack lasted one minute, involved DNS amplification and UDP flooding, and was carried out using approximately 15,000 bots. The bots ran a variant of the Mirai malicious code on compromised IoT devices and GitLab instances containing the CVE-2021-22205 vulnerability. A critical vulnerability allows remote code execution. The problem received a maximum score of 10 on the CVSS scale. In April of this year, a patch was released for this vulnerability, but according to researchers, the problem is still present on thousands of systems.

As noted in Cloudflare, the total number of DDoS attacks of terabit power increased in the third quarter of the year. The number of incidents at the network level increased by 44% compared to the previous quarter.

We will remind, earlier, Microsoft specialists recorded a DDoS attack with a capacity of 2.4 Tbit / s in August this year. The attack targeted a Microsoft Azure client in Europe and was 140% higher than the maximum attack throughput recorded by Microsoft in 2020. The attack lasted over 10 minutes, with short bursts of traffic reaching peak power of 2.4 Tbps, 0.55 Tbps, and 1.7 Tbps. Azure was able to stay online throughout the entire attack.

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.
