ReliaQuest’s recently published report reveals disturbing methods employed by cyber attackers to exploit cloud environments, shedding light on some sophisticated tactics they use to bypass security measures. Analyzing true-positive alerts from December 2023 to September 2024, the report particularly focuses on how initial access and discovery commands are executed against public-facing cloud APIs. Notably, 28% of these alerts originated from self-service password reset requests, signaling determined attempts to gain administrator privileges. Within Kubernetes environments, the GetVersion command emerged in 31% of alerts, indicating active probing for software vulnerabilities.
A significant revelation from the report points to the extensive use of known malicious IP addresses in over half of the analyzed attacks, illustrating frequent scanning for exploitable vulnerabilities. A novel phishing technique has also come to light, involving the use of cloud-storage SaaS platforms like OneNote through SharePoint or Google Drive to host malicious links. Attackers skillfully employ phishing emails to direct recipients to these legitimate platforms, which complicates detection efforts for traditional security systems.
The Evolution of Phishing Tactics
Phishing, constituting 71.1% of the observed techniques in 2023, exploits users’ trust in familiar platforms such as Google Drive or Dropbox. Traditional email filtering systems may not consistently recognize these emails as malicious, permitting them to evade initial lines of defense. Recognizing this, ReliaQuest has developed detection rule libraries and GreyMatter containment and response playbooks to bolster security measures, operating independently of standard email tools.
The report underscores the menace of cloud environment hijacking, which could lead to misuse for activities like cryptocurrency mining or launching additional phishing schemes utilizing compromised resources. To counter these threats, strict monitoring and effective management of API keys are imperative. Implementing API gateways equipped with SSL certificates is recommended for added layers of identity verification, providing a more secure shield against potential intrusions.
Strategic Security Enhancements
ReliaQuest’s latest report uncovers alarming methods cyber attackers use to compromise cloud environments, highlighting sophisticated tactics to bypass security defenses. Analyzing true-positive alerts from December 2023 to September 2024, the report emphasizes the strategies used in initial access and discovery commands targeting public-facing cloud APIs. Strikingly, 28% of these alerts stemmed from self-service password reset requests, suggesting determined efforts to acquire administrator privileges. In Kubernetes systems, the GetVersion command appeared in 31% of alerts, signifying active probing for software weaknesses.
The report also highlights the pervasive use of known malicious IP addresses in over half of the analyzed attacks, underscoring frequent scans for vulnerabilities. Additionally, a new phishing technique has emerged, leveraging cloud-storage SaaS platforms like OneNote via SharePoint or Google Drive to host malicious links. Attackers craft phishing emails directing victims to these legitimate platforms, complicating detection for traditional security systems. This evolving threat landscape underscores the need for enhanced security measures to protect cloud environments.
