A hacker can implement 71% of events that are unacceptable for business

Published

An attacker can not only penetrate the local network of 93% of companies, but also implement 71% of events that are unacceptable for business.

Experts analyzed the results penetration testing and found that in 93% of cases, an external attacker can penetrate the network perimeter and gain access to local network resources, and it takes an average of two days to penetrate the company’s internal network. In 100% of the companies surveyed, an internal attacker could gain complete control over the infrastructure.

The study was carried out among financial organizations (29%), fuel and energy organizations (18%), government (16%), industrial (16%) and IT companies (13%), as well as companies from some other industries.

While analyzing the protection against an external attacker, Positive Technologies experts managed to overcome the network perimeter in 93% of projects. According to the company’s experts, this indicator is already many years remains at a high level and confirms that for almost any corporate infrastructure, criminals will be able to pick up the key and get inside.

“In 20% of projects, verification of information security events unacceptable for companies was carried out,” says Yekaterina Kilyusheva, head of the research group of the information security analytics department at Positive Technologies. – In these projects, the companies, on average, designated six unacceptable events that needed to be implemented. According to our clients, the greatest danger for them is represented by events related to disruption of technological processes, service delivery processes, theft of money and important information. In total, it was possible to confirm the possibility of implementing 71% of the designated events. It is noteworthy that an attack that will lead to the implementation of an invalid event will take an attacker no more than a month. The development of attacks on some systems can even happen in a matter of days. “

Despite the fact that financial institutions are considered one of the most protected, within the framework of verification of unacceptable events in each bank, specialists managed to perform actions that disrupt the bank’s business processes and affect the quality of services provided.

For example, access to the ATM management system was obtained with the possibility of stealing funds.

The path of an attacker from external networks to target systems begins by crossing the network perimeter. According to the research, on average, it takes two days to penetrate a company’s internal network. Experts called the selection of credentials (71% of projects) the main way to penetrate the corporate network, primarily attributing this to the fact that employees like to set simple passwords, including for accounts used to administer systems.

An attacker with credentials with domain administrator privileges could gain many other credentials to horizontally navigate the corporate network and gain access to key computers and servers. Administrative, virtualization, protection, or monitoring tools often help an intruder gain access to isolated network segments. According to the research, in most companies there is no network segmentation by business processes, which makes it possible to develop several vectors of attacks until several invalid events are implemented simultaneously.

“To build an effective protection system, you need to understand what unacceptable events are relevant for a particular company, – comments by Ekaterina Kilyusheva. – Moving along the path of the business process from unacceptable events to target and key systems, you can trace the relationship and determine the sequence of applied protection measures. To make it harder for an attacker to move within the corporate network towards the target systems, we propose a number of interchangeable and complementary measures, including the separation of business processes, configuration security control, enhanced monitoring and lengthening the attack chain. The choice of these or those solutions should be based on the capabilities of the company and its infrastructure. “

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.
