3. Hacker claims to have decrypted Apple's Secure Enclave, destroying key piece of iOS mobile security by Brandon Vigliarolo

This week, a hacker going by xerub, released a full decryption key for Apple’s Secure Enclave Processor (SEP). The SEP operates separately from the rest of the device and generates the device’s Unique ID. It also handles Apple’s Touch ID transactions. With the decryption key, the SEP firmware’s code will be exposed as well as its vulnerabilities. This could be a hit to Apple’s mobile security, though xerub claims his intention for releasing the key was to add to the security of SEP. It’s too early to tell what the effects will be but there is still a ton of work that would need to go into exploiting this decryption and being able to compromise customer data.

The Group has been sending spear-phishing emails containing Word documents disguised with job descriptions and internal policies. There were several similarities in this series of attacks to past Lazarus Group campaigns, and with Trump’s recent nuclear threats against North Korea, it’s not a far leap.
