BazarLoader’s ingenious social engineering tactic that uses malicious call centers to spread the malware, aka BazarCall method, is back in action. This time, users are being tricked into a false subscription with movie-streaming service BravoMovies, which they have never signed up for. The ultimate purpose of the loader is to deploy ransomware and other types of malware onto the victim’s system.

A new design flaw in Apple’s popular new chip (M1) for Macbooks and iMac has raised concern. Identified as M1RACLES, the flaw can allow two apps running on the same device to covertly exchange data via a secret channel at the CPU level.

It is not just Apple users who are in trouble following the discovery of this new flaw, users of the Checkbox Survey online tool are also at risk due to a remote code execution vulnerability exploited in the wild.

Top Vulnerabilities Reported in the Last 24 Hours

A newly found M1RACLES bug has been found impacting Apple M1 chips. Tracked as CVE-2021-30747, the bug allows two apps running on the same device to exchange data between one another via a secret channel at the CPU level, without using memory, sockets, files, or any other normal operating system features.

Vulnerable Visual Studio Code extensions fixed
Severe security flaws fixed in popular Visual Studio Code extensions can lead to compromise of local machines, as well as build and development systems. Some of the extensions in question are LaTex Workshop, Rainbow Fart, Open in Default Browser, and Instant Markdown. These vulnerable extensions can be exploited to run arbitrary code on a developer’s system remotely, which could ultimately lead to supply chain attacks.

Checkbox Survey flaw exploited
A Checkbox Survey vulnerability tracked as CVE-2021-27852 is being exploited in the wild. The flaw is related to the insecure deserialization of view state data and can allow a remote attacker to execute arbitrary code without authentication. Users are encouraged to upgrade to Checkbox survey version 7.0 or later.

Siemens addresses code execution flaw
Siemens has released an advisory for several vulnerabilities affecting its Solid Edge product. The flaws include four high-severity memory corruption issues and one medium-severity XXE bug. The vulnerabilities can be exploited by tricking users into processing malicious CATPart, 3DXML, STP, PRT, or JT files.

Overlooked flaws in GraphQL
Endpoints using GraphQL may be at risk due to failures to mitigate cross-site request forgery vulnerabilities. In total, there are 14 such flaws that remain unpatched.

Top Scams Reported in the Last 24 Hours

Steam used in a phishing attack
A new type of phishing attack that targets the popular gaming platform Steam has been uncovered by users.
