"We found almost 43 TB of data exposed and 1,000 apps affected by the HospitalGown vulnerability."
Echoing the findings of a similar recent report, Appthority has published investigation results that found nearly 43 TB of enterprise data was exposed on cloud back-ends, including personally identifiable information (PII).
The company's new "2017 Q2 Enterprise Mobile Threat Report" report (free upon providing registration info), Appthority found "data leakage" from mobile apps that send data to unsecured cloud back-ends. Appthority said mobile security concerns typically focus on a triad of other factors -- apps, device threats and network threats -- but unsecured back-ends are a new threat vector that goes hand-in-hand with cloud computing. This data leakage on the back-end was dubbed the "HospitalGown" threat by the company because of that garment's open back-end.
"In total, we found almost 43 TB of data exposed and 1,000 apps affected by the HospitalGown vulnerability," Appthority said in a blog post last week. "Looking at a subset of 39 apps, we still found 280 million records exposed, a total of about 163 GB of data. This is a staggering amount of leaked information, and in some cases represents the entirety of customer or operational data for an enterprise."
The report mirrors the findings of an earlier report by RedLock Inc., which revealed many security issues primarily caused by user misconfigurations on public cloud platforms, with Amazon Web Services Inc. (AWS) figuring prominently. RedLock claimed it found 82 percent of hosted databases remain unencrypted, among many other problems.
The AWS cloud was also mentioned in the new report from Appthority. One of the key findings of the report said: "The enterprise threat is real: The apps connect to unsecured databases on a range of popular enterprise services, including Elasticsearch and Amazon Web Services."
Unsecured Elasticsearch servers and MongoDB databases were prime targets of a series of ransomware attacks earlier this year that generated widespread publicity in the security field. However, that publicity apparently wasn't enough to significantly alleviate the issue.
"As our findings show, weakly secured back-ends in apps used by employees, partners and customers create a range of security risks including extensive data leaks of personally identifiable information (PII) and other sensitive data," the report states. "They also significantly increase the risk of spear phishing, brute force login, social engineering, data ransom, and other attacks. And, HospitalGown makes data access and exfiltration far easier than other types of attacks."
Key findings of the report as listed by the company include:
The company said its Mobile Threat Team identified the HospitalGown vulnerabilities with a combination of its dynamic app analysis tool and a new back-end scanning method, looking at the network traffic on more than 1 million enterprise mobile apps, both iOS and Android.
As with the misconfiguration problems identified in the RedLock report, Appthority emphasized that all cases of HospitalGown vulnerabilities were caused by human errors, not malicious intent or inherent infrastructure problems.
Appthority said it disclosed information about the exposed data to app developers and to affected providers, such as AWS.
"In some cases, the issues were remediated immediately," the company said. "Unfortunately, in others, we received no response and the data is still exposed."
