Meta's Rush to Topple Twitter Sets Up Looming Privacy Debate
Meta has a history of conflict with regulators, owing to its liberal approach to consumer privacy. The EU has already fined the media giant to the tune of nine figures or more on multiple occasions.
Judging by its entry in the Apple app store, it's no wonder that Threads is being shielded from EU scrutiny.
Browsing history, geolocations, health and financial information, and much more are all up for grabs.
There's even a dedicated category for "sensitive information" which, according to Apple's documentation, includes "racial or ethnic data, sexual orientation, pregnancy or childbirth information, disability, religious or philosophical beliefs, trade union membership, political opinion, genetic information, or biometric data".

CISA and FBI warn of Truebot infecting US and Canada based organizations
Several hours after the initial infection, Truebot has been observed injecting Cobalt Strike beacons into memory.
The beacons remain in a dormant mode for the first few hours prior to initiating additional operations.
“Based on confirmation from open-source reporting and analytical findings of Truebot variants, the authoring organizations assess cyber threat actors are leveraging both phishing campaigns with malicious redirect hyperlinks and CVE-2022-31199 to deliver new Truebot malware variants.” concludes the joint report published by CISA, the FBI and MS-ISAC and the Canadian Centre for Cyber Security".

Scientists Propose An All-Optical Labeling Method for Encrypted Fiber Optic Tags
The fiber optic tag is based on a fiber Bragg grating array prepared by femtosecond laser direct writing.
By cleverly utilizing the spatial distribution, reflectivity, and reflection wavelength of the gratings, the tag can carry rich information.
When using an optical time-domain reflectometer for reading, a specific administrator can perform complete and error-free information recovery.
The team prepared a fiber Bragg grating array using femtosecond laser multi-pulse exposure, which can control the characteristics of different grating fragments, such as reflectivity.
By utilizing the reflected signal of the grating to increase the number of switch states that the fiber optic tag can represent, the storage capacity of the fiber tag is improved.
