An Iranian nation-state hacking group typically referred to as Charming Catan has been observed deploying a C++ variant of a well-known malware known as BellaCiao.
Russian cybersecurity agency Kaspersky, which dubbed the model new mannequin. Bella cpptalked about it discovered the sample as part of a “newest” investigation proper right into a compromised machine in Asia that was moreover contaminated with the BellaCiao malware.
