What makes TeamTNT notably noteworthy shouldn’t be solely its targets — primarily cloud-based software program and providers — but additionally how shortly it has developed present strategies and built-in new ones into its campaigns.
Be that as it could, in many of the group’s campaigns, TeamTNT’s methodology of entry is kind of constant: It makes use of quite a few instruments to scan the web for potential targets with misconfigurations and vulnerabilities, and takes benefit of those weaknesses to realize a foothold within the programs. TeamTNT makes a speciality of discovering exploitable gaps in safety, be they unsecured Redis situations, uncovered Docker APIs, susceptible internet-of-things (IoT) units, or leaked credentials.
For a sufferer group, the group’s payloads, if efficiently deployed, might at greatest be disruptive — as with cryptocurrency miners — and at worst trigger heavy financial loss and even reputational injury — particularly if the group manages to exfiltrate credentials and different delicate info from the group.
TeamTNT has largely been profitable due to varied exploitable safety weaknesses. Whereas it’s admittedly tough to utterly get rid of these, enterprises must prioritize safety as a lot as they will. They need to implement the best methods for shielding the cloud from exterior assaults, whereas additionally being conscious of which facets of the shared duty mannequin they should be accountable for.
Listed below are a number of greatest practices that organizations ought to take into account placing into place:
Grant customers entry solely to the components of the system they want with a view to cut back potential entry factors and include injury even within the occasion of a profitable assault. This is named the precept of least privilege.
Implement personal keys authentication for Safe Shell (SSH) on the shopper aspect for stronger entry management safety.
Recurrently patch and replace programs and units to attenuate situations of vulnerability exploitation. For organizations that want time to implement patches, digital patching can present buffer time, serving to shield their programs from vulnerabilities whereas updates are nonetheless being ready.
Enterprises also needs to think about using safety options corresponding to the Development Micro Cloud One™ platform, which protects cloud-native programs by securing continuous-integration and continuous-delivery (CI/CD) pipelines and purposes. The platform contains:
Workload Safety: runtime safety for workloads
Container Safety: automated container picture and registry scanning
File Storage Safety: safety for cloud recordsdata and object storage providers
Community Safety: cloud community layer for intrusion prevention system (IPS) safety
Utility Safety: safety for serverless capabilities, APIs, and purposes
Conformity: real-time safety for cloud infrastructure — safe, optimize, comply
