JFrog researchers found multiple campaigns planting millions of malicious "imageless" containers on Docker Hub over the past five years, highlighting how open source registries can enable supply chain attacks. More than four million Docker Hub repositories are imageless and contain only the repository documentation, according to JFrog security researcher Andrey Polkovnichenko. The documentation is unrelated to the container. Instead, it is a page that directs users to phishing or malware sites.

According to security researchers at Sophos, average ransom payments surged by 500% in the past year to reach $2m per payment. This compares to an average payment of $400,000 calculated by Sophos in its 2023 study, demonstrating that ransomware operators are seeking increasingly large payoffs from victims. The researchers noted that nearly two-thirds (63%) of ransom demands made in the past year were $1m or more, with 30% of demands demanding over $5m. This is despite a reduction in the rate of organizations being hit by ransomware in the past year, at 59%.
