Washer Electrical Equipment Bond. WEEB or Washer Electrical Equipment Bond is a type of electrical component that allows the connection of various metals to a copper conductor.

Because of galvanic corrosion, dissimilar metals exposed to an electrolyte and electrically bonded together are unstable: the interface between the two materials will corrode one of them, and the structure will eventually fail. Copper is commonly used as an electrical bonding conductor because of its electrical properties. However, copper reacts galvanically with common structural materials like aluminium and zinc-coated steel.

The Washer Electrical Equipment Bond addresses the engineering problem by sandwiching a chemically non-reactive interface of 304 stainless steel between the metal structural element and the bonding electrical component. The stainless steel interface uses sharp protrusions to dig into the structural metal's surface oxide layer and bond electrically with the metal body. On the other side of the interface, a clamp, constructed of a conductive material compatible with copper, provides the physical attachment to the bare conductor cable. The attachment comes usually in the form of a screw terminal.

Uses
The WEEB is commonly used to provide electrical bonding for exterior metal structures like solar panel installations.

Aluminium arsenide antimonide. Aluminium arsenide antimonide, or AlAsSb (AlAs1-xSbx), is a ternary III-V semiconductor compound. It can be considered as an alloy between aluminium arsenide and aluminium antimonide. The alloy can contain any ratio between arsenic and antimony. AlAsSb refers generally to any composition of the alloy.

Preparation 
AlAsSb films have been grown by molecular beam epitaxy and metalorganic chemical vapor deposition on gallium arsenide, gallium antimonide and indium arsenide substrates. It is typically incorporated into layered heterostructures with other III-V compounds.

Structural and Electronic Properties 

The room temperature (T = 300 K) bandgap and lattice constant of AlAsSb alloys are between those of pure AlAs (a = 0.566 nm, Eg = 2.16 eV) and AlSb (a = 0.614 nm, Eg = 1.62 eV). Over all compositions, the bandgap is indirect, like it is in pure AlAs and AlSb. AlAsSb shares the same zincblende crystal structure as AlAs and AlSb.

Applications 
AlAsSb can be lattice-matched to GaSb, InAs and InP substrates, making it useful for heterostructures grown on these substrates.

AlAsSb is occasionally employed as a wide-bandgap barrier layer in InAsSb-based infrared barrier photodetectors. In these devices, a thin layer of AlAsSb is grown between doped, smaller-bandgap InAsSb layers. These device geometries are frequently referred to as "nbn" or "nbp" photodetectors, indicating a sequence of an n-doped layer, followed by a barrier layer, followed by an n- or p-doped layer. A large discontinuity is introduced into the conduction band minimum by the AlAsSb barrier layer, which restricts the flow of electrons (but not holes) through the photodetector in a manner that reduces the photodetector's dark current and improves its noise characteristics.

Initial access broker. Initial access brokers (or IABs) are cyber threat actors who specialize in gaining unauthorized access to computer networks and systems and then selling that access to other threat actors such as ransomware. IABs are parts of ransomware as a service economy, also called "cybercrime as a service economy".

Description 
IABs use a variety of methods to gain initial access, including exploiting vulnerabilities in remote access services like RDP and VPNs, bruteforcing login credentials, and leveraging malware that steals account information. Access are often sold on auctions in underground criminal forums or directly provided to ransomware affiliate groups to expedite attacks. 

IABs seek access to virtual private networks, remote desktop protocol, Web applications, and email servers. Email services will be used to commit spear phishing and business email compromise (BEC).

In 2020, the average price for a network access is $5,400. The median price is $1,000.

By providing initial access, IABs allow other cyber criminals like ransomware groups to more quickly infiltrate networks and launch attacks without wasting time to gain entry themselves. This access as a service model - in analogy to the software as a service model - provides scalability and efficiency to cybercriminal operations. Ransomware in particular has benefited from collaboration with IABs.
