Top Highlights
- Attackers increasingly use stolen credentials and access tokens to infiltrate systems, making breaches harder to detect and more costly.
- Extended, unnoticed activity from compromised accounts can lead to severe damage including data theft, financial loss, and reputational harm.
- Effective detection must focus on understanding and responding to suspicious account activity directly within identity systems, especially in cloud and remote work environments.
Threat Overview, Techniques, and Targets
Hackers are increasingly using stolen passwords, usernames, and access tokens to infiltrate company systems. Unlike traditional malware attacks, these cybercriminals log in with legitimate credentials. This makes their activity harder to detect, as they appear as normal users at first. Industry research shows that the use of stolen credentials surged by 71% in 2023. This type of attack accounts for about 30% of incidents reported by IBM’s Threat Intelligence Index. Targets include customer data, internal messages, financial systems, and other sensitive resources. As more employees, contractors, and third-party apps access company systems, each login becomes a potential risk. The attack technique relies on credential theft and misuse, which allows access without raising immediate alarms.
Impact, Security Implications, and Remediation Guidance
When stolen credentials go unnoticed, companies face serious consequences. They risk data breaches, operational downtime, financial loss, legal issues, and damage to reputation. Longer activity periods mean more damage. Therefore, quick detection and context are crucial. Detection systems need to move closer to where the threat exists—inside identity systems. Such systems should understand not only that a login occurred but also whether the activity is unusual. This approach can help security teams respond faster and prevent widespread damage. Currently, specific remediation guidance is not provided here. Organizations should consult their security vendors or authoritative sources to develop effective countermeasures to address credential-based threats.
