Cloud systems are attacked within minutes of exposure, with weak passwords and cryptomining being the biggest causes of breaches and hidden costs.

Cloud attackers arrive within minutes, not days

Google’s Cloud Threat Intelligence report shows that once a cloud server is exposed online, attackers can find and target it in as little as 30 minutes, meaning there is almost no safe window after deployment.

Weak passwords remain the biggest entry point for cloud breaches

Nearly half of cloud intrusions (around 48%) happen due to weak or missing passwords, making poor authentication the most common security failure in cloud environments.

Unpatched software and leaked credentials also contribute significantly

About 26% of attacks exploit unpatched vulnerabilities, while some incidents happen due to accidental exposure of secrets or API keys, often through public code repositories like GitHub.

Most cloud attacks are silent—not ransomware

Instead of obvious ransomware attacks, most intrusions are quiet and focused on long-term abuse of resources rather than immediate disruption.

Cryptomining is the most common post-breach activity

Around 86% of compromised cloud systems are used for cryptomining, where attackers secretly use the victim’s compute power to generate cryptocurrency profits.

Compromised servers are also used to attack others

Hackers often turn infected cloud servers into tools for scanning, DDoS attacks, spam distribution, and malware hosting, expanding their criminal operations.

Cloud misuse leads to direct financial loss

Because cloud billing depends on usage, attackers can silently increase costs by consuming resources, causing victims to pay for malicious activity without realizing it.
