“Ransomware, not surprisingly, is one of the most widely reported cybercrimes in the public cloud. The most successful ransomware attacks include data in the public cloud, according to the State of Ransomware 2020 report, and attackers are shifting their methods to target cloud environments that cripple necessary infrastructure and increase the likelihood of payment,” said Chester Wisniewski, principal research scientist, Sophos. “The recent increase in remote working provides extra motivation to disable cloud infrastructure that is being relied on more than ever, so it’s worrisome that many organizations still don’t understand their responsibility in securing cloud data and workloads. Cloud security is a shared responsibility, and organizations need to carefully manage and monitor cloud environments in order to stay one step ahead of determined attackers.”
The Unintentional Open Door: How Attackers Break In
Accidental exposure continues to plague organizations, with misconfigurations exploited in 66% of reported attacks. Detailed in the SophosLabs 2020 Threat Report, misconfigurations drive the majority of incidents and are all too common given cloud management complexities.
Additionally, 33% of organizations report that cybercriminals gained access through stolen cloud provider account credentials. Despite this, only a quarter of organizations say managing access to cloud accounts is a top area of concern. Data from Sophos Cloud Optix, a cloud security posture management tool, further reveals that 91% of accounts have overprivileged identity and access management roles, and 98% have multi-factor authentication disabled on their cloud provider accounts.
The Silver Lining
Nearly all respondents (96%) admit to concern about their current level of cloud security, an encouraging sign that it’s top of mind and important. Appropriately, “data leaks” top the list of security concerns for nearly half of respondents (44%); identifying and responding to security incidents is a close second (41%). Notwithstanding this silver lining, only one in four respondents view lack of staff expertise as a top concern.
