PyPI – Library pymafka Expose data via open backdoor
A malicious library pymafka has been released on PyPI with the intent to exfiltrate data
PyKafka is a widely used Apache Kafka client that counts over four million downloads on the PyPI registry.
The library implemented the attack known as typosquatting where users mistake the library capital for lowercase
The library was fortunately promptly removed, nonetheless there are 325 users who downloaded the library
the infection begins with the execution of the ‘setup.py’ script found in the package.
This script detects the host operating system and, depending on whether it is Windows, Linux, or Darwin (macOS), fetches a compatible malicious payload that is executed on the system.
For Linux systems, the Python script connects to a remote URL at 39.107.154.72 and pipes the output to the bash shell. Unfortunately, that host is down at the time of this writing, so it is unclear what commands are executed, but it is believed to open a reverse shell.
For Windows and macOS, the payload is a Cobalt Strike beacon, which provides remote access to the infected device.
Cobalt Strike is a widely abused penetration testing suite that features powerful traits such as command execution, keylogging, file actions, SOCKS proxying, privilege escalation, credential stealing, port scanning, and more.

To avoid similar attacks always check if the package has description and is from a reputable author as well as checking for typos
Software developers should scrutinize package names and details and double-check their selection of building blocks when something appears funky.

IOS – Remote Execution of malware via Bluetooth
Security researchers were able to exploit successfully vulnerability in the Bluetooth, NFC, and ultra-wideband (UWB) that are all hardwired to the phone’s secure element. The researchers were able to write to the Bluetooth chip in an iPhone 13 by exploiting a legacy feature that requires iOS to be able to write to the executable RAM regions using a vendor-specific host-controller interface (HCI) command.
Workaround: disable the Find My network as a device policy this can be implemented as policy for your workforce with iPhones running iOS 15
