US Congress Reveals Details of Cyberattack on JBS

Published

The REvil ransomware put heavy pressure on JBS during the attack.

At a Special Hearing in the U.S. Congress on Counter-Hacking Strategies, there was made public information about a cyberattack that halted the production processes of the world’s largest meat food producer JBS in the United States and Australia.

As the results of the investigation of the cyberattack showed, the attackers gained access to the old network administrator account, which was not deactivated and was protected only by a weak password. The company faced significant ransomware pressure, making it harder to stop the attack.

JBS paid a $ 11 million ransom in bitcoin to regain access to its systems. The FBI linked the attack on JBS to the REvil hacker group (also known as Sodinokibi).

“The pressure was compounded by assurances from the attackers that the ransom payment would resolve the situation and prevent negative publicity for the company. For example, after the initial JBS hack, REvil operators told the company, “We can unlock your data and keep everything secret. All we need is a ransom, ”said Carolyn B. Maloney, chair of the US Oversight and Government Reform Committee.

As JBS explained to the committee, in addition to the cost of restoring its systems from backups, the company faced other pressing challenges and potential costs, including obligations to customers and employees, and the need to process meat products at its facilities.

During the cyberattack, the attackers tried to present themselves as business partners or even “consultants.” REvil advised JBS not to panic as the group is “in business, not war.” REvil even provided recommendations for cryptocurrency exchanges where the company could buy cryptocurrency, highlighting that one of the exchanges does not need verification.

The company made the decision to pay the ransom despite having at least some system backups that were unaffected by the attacks. JBS later reported that the vast majority of its properties were in working order at the time the ransom was paid. JBS paid the ransom to “mitigate any unforeseen problems associated with the attack and to ensure the security of the data,” the company said.

As the cybercriminals assured during the negotiations, they are ready to provide the decryption key and delete copies of the stolen data if the company pays the required amount. They stressed that it was in their best interest to act in accordance with the agreement. However, the hackers never provided JBS with evidence that all copies of the stolen data were destroyed.

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.
