In this advisory we include information on the discovery of malicious encryptors on Apple computers, Google Chrome zero day vulnerability, and some tips for good data privacy practice.
Discovery of Ransomware Samples in Apple Macs
Samples of ransomware encryptors have been discovered purportedly from the LockBit ransomware gang, marking the first known example of a prominent ransomware group toying with macOS versions of its malware.
LockBit appears to have created both a version of the encryptor targeting newer Macs running Apple processors and older Macs that ran on Apple’s PowerPC chips.
Researchers say the LockBit MacOS encryptors appear to be in a very early phase rather than anything that’s fully functional and ready to be used but it could be an indicator of future plans.
