The TA575 constellation sends thousands of emails to hundreds of organizations.
Proofpoint specialists discovered a malicious campaign in which cybercriminals from the TA575 group spread Dridex malware using emails about the hit Netflix series Squid Game.
The emails contain messages such as “The Squid Game is back, watch the new season before everyone else”, “Client invitations to access the new season,” “Previews of commercials for the new season of the Squid Game,” etc.
Experts have identified thousands of honeypot emails targeted at various industries in the United States. Some emails attempt to lure victims into offering a role in the series if the user downloads and fills out an attached document.
“Attachments are Microsoft Excel documents with macros that, when enabled, download the partner ID of the banking Trojan Dridex 22203 from Discord URLs,” the experts explained.
Dridex is a banking Trojan used to steal funds directly from the victim’s bank account. The malware is also used to gather information or act as a downloader for malware, including ransomware.
“The TA575 sends an average of thousands of emails for every campaign that affects hundreds of organizations. TA575 also uses the Discord Content Delivery Network (CDN) to host and distribute Dridex, ”said the experts.
Attackers actively target users through mobile channels such as SMS, social media platforms, third-party messaging apps, games, and even dating apps.
Vulnerability found in the Apple M1 processor that cannot be closed programmatically
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 single-chip systems
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.
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.
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.
