“An Amazon email scam can look exactly like a real Amazon email, or can be poorly crafted, and everything in between,” according to Alex Hamerstone, a director with the security-consulting ...
The vertex-connectivity statement of Menger's theorem is as follows: . Let G be a finite undirected graph and x and y two nonadjacent vertices. Then the size of the minimum vertex cut for x and y (the minimum number of vertices, distinct from x and y, whose removal disconnects x and y) is equal to the maximum number of pairwise internally disjoint paths from x to y.
Technical support scams rely on social engineering to persuade victims that their device is infected with malware. [15] [16] Scammers use a variety of confidence tricks to persuade the victim to install remote desktop software, with which the scammer can then take control of the victim's computer.
In the undirected edge-disjoint paths problem, we are given an undirected graph G = (V, E) and two vertices s and t, and we have to find the maximum number of edge-disjoint s-t paths in G. Menger's theorem states that the maximum number of edge-disjoint s-t paths in an undirected graph is equal to the minimum number of edges in an s-t cut-set.
Tech expert Kurt “CyberGuy" Knutsson says a tech support scam used a fake Windows Defender pop-up, tricking the victim to call and download software. ... Read more of my review of the best ...
A package redirection scam is a form of e-commerce fraud, where a malicious actor manipulates a shipping label, to trick the mail carrier into delivering the package to the wrong address. This is usually done through product returns to make the merchant believe that they mishandled the return package, and thus provide a refund without the item ...
The edge connectivity of is the maximum value k such that G is k-edge-connected. The smallest set X whose removal disconnects G is a minimum cut in G . The edge connectivity version of Menger's theorem provides an alternative and equivalent characterization, in terms of edge-disjoint paths in the graph.
Placards and a papier-mâché Jeff Bezos head at London "Make Amazon Pay" protest in 2021. Amazon has been criticized on many issues, including anti-competitive business practices, its treatment of workers, offering counterfeit or plagiarized products, objectionable content of its books, and its tax and subsidy deals with governments.
