Warshipping: Hacking The Mailroom, Jackson Szwast, Bryson Payne

KSU Proceedings on Cybersecurity Education, Research and Practice

Everyone knows what package shipping is, but not everyone knows what warshipping is. Corporate mailrooms are rarely considered as part of the cybersecurity attack surface of most organizations, but they offer physical access to millions of uninspected packages daily. UPS shipped 5.5 billion items last year, with their daily average being 21.9 million items and operating through 1,800 locations in 2020. FedEx shipped 6.5 million packages daily and operates 2,150 locations. The United States Postal Service delivered 143 billion pieces of mail in 2019. Increasingly the world’s consumers are relying on e-commerce, and during the recent COVID-19 pandemic, package deliveries …

Tidal And Wave Energy: A Viability Overview, Visar Bejta

UBT International Conference

The global quiescent capacity of tidal energy is utterly prodigious. A potential wide-ranging output of electric power from thalassic tideway and waves — besides the inherent wind resource — is appealing as it provides, amongst other things, adequate grounds for an industrial viability analysis. Apropos, in recent years, vast improvements have been observed in the domain of tidal energy exploitation. Furthermore, economic viability is gradually gaining ground in a process that comprises considerable funding from sphere trendsetters and frontrunners. Palpable technical development, besides the favorable treatment from the communications industry, has boosted the validity of this particular renewable energy arrangement.
