- Scalable and agile deployment: Assault infrastructure is usually light-weight and simply deployed on cloud platforms comparable to Firebase, Oracle Cloud, GitHub, and so on. This makes these campaigns simple to scale and tougher for defenders to establish and dismantle shortly.
- Lowered obstacles to entry: Toolkits like LogoKit are available on underground boards, offering even much less tech-savvy people with the instruments wanted to launch assaults.
