Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
Fluent use reflect-metadata
for reflection and you need two conditions for proper functioning:
"experimentalDecorators": true
to your tsconfig.json file"emitDecoratorMetadata": true
to your tsconfig.json fileThis component has an identical implementation approach as ASP.NET Core
and has a number of inconveniences.
The reflection can not be realized without decorators and therefore it is necessary to use the @Injectable()
decorator for all classes to use dependency injection.
Example of usage:
@Injectable()
export class PingService {
}
This decorator only emit metadata and does not process anything.
The service collection is carried out with the help of the ServiceCollection
class and it has three main methods that add the right lifetime:
addSingleton()
- an instance of a service is always the sameaddScope()
- an instance of a service is always the same if its call occurs in one scopeaddTransient()
- the service instance is always uniqueExample of usage:
@Main()
export class Startup {
configureServices(services: ServiceCollection) {
services.addSingleton(PingService);
}
}
You can also get an instance of the service in the constructor:
@Injectable()
export class PongService {
constructor(pingService: PingService) {
}
}
When calling PongService
the instance will receive PingService
as constructor argument.
