The Danger of Minimum Exposures: Understanding Cross-App Information Leaks on iOS through Multi-Side-Channel Learning.

Article Synopsis
- Research has primarily focused on single-channel side-channel leaks (like memory or network traffic), while the risks of using multiple channels together have been less explored.
- The study introduces a novel technique called Mischief that employs probabilistic searches to find the best combination of side channels to extract the most information about target activities (such as app usage and web visits) on iOS devices.
- Findings show that Mischief effectively identifies activities with high confidence, suggesting that current Apple protections are insufficient, and highlighting the need for improved, comprehensive security measures against information leaks.
Immobilized microorganism technology has attracted increasing attention for high concentration of microbes, low cell loss and high resistance to impact of environment. The microbial reduction of nitrate in the presence of sediment-based biochar (SBC) and nanoscale zero-valent iron (nZVI) was investigated in four different free systems. NZVI-SBC/bacteria system realized the best nitrate removal of 97.

Therefore, we prepared nanoscale zerovalent iron loaded on sediment-based biochar (nZVI-SBC) to conduct nitrate and phosphate removal at the same time. The characterization demonstrated that nZVI-SBC was successfully synthesized, which had obvious advantages for larger specific surface area and better dispersion compared with pure nZVI.
