Unknown person stole $ 55 million from bZx DeFi platform

Representatives of bZx suggested that the hacker get in touch with them and discuss the possibility of a refund for a reward.

A hacker stole $ 55 million in cryptocurrency from the DeFi platform bZx, which allows users to borrow and lend and speculate on cryptocurrency fluctuations.

How reported bZx representatives, the platform developer received a phishing email containing a Word document with malicious macros disguised as a legitimate attachment. After opening a malicious attachment, a script was launched on the developer’s computer that compromised the mnemonic phrase for accessing his cryptocurrency wallet.

The attacker emptied the developer’s wallet and stole two private keys used to integrate the bZx platform with the Polygon and Binance Smart Chain (BSC) blockchains. Using these keys, the hacker stole bZx funds from Polygon and BSC, along with funds from a small number of users who approved unlimited spending transactions for both tokens in their accounts.

According to bZx representatives, the platform is currently still trying to establish the exact amount of the stolen funds. However, cybersecurity firm SlowMist estimates that it is in excess of $ 55 million.

In the aftermath of the incident, bZx disabled its site’s user interface in order to block users from depositing new funds. In addition, the platform cooperates with various cryptocurrency exchanges in order to track down the attacker and freeze the stolen funds.

Among other things, bZx approached the hacker, inviting him to contact representatives of the platform and discuss the possibility of returning the stolen cryptocurrency for a reward. bZx hopes to repeat the story of PolyNetwork, when a hacker returned all the $ 600 million stolen from the platform.

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.
