Critical Cosmos Database Flaw Affected Thousands of Microsoft Azure Customers

Cloud infrastructure security company Wiz on Thursday revealed details of a now-fixed Azure Cosmos database vulnerability that could have been potentially exploited to grant any Azure user full admin access to other customers' database instances without any authorization. The flaw, which grants read, write, and delete privileges, has been dubbed " ChaosDB ," with Wiz researchers noting that "the vulnerability has a trivial exploit that doesn't require any previous access to the target environment, and impacts thousands of organizations, including numerous Fortune 500 companies." Cosmos DB is Microsoft's proprietary  NoSQL database  that's advertised as "a fully managed service" that "takes database administration off your hands with automatic management, updates and patching." The Wiz Research Team reported the issue to Microsoft on August 12, after which the Windows maker took steps to mitigate the issue within 48 hours of r

Can Data Protection Systems Prevent Data At Rest Leakage?

Protection against insider risks works when the process involves controlling the data transfer channels or examining data sources. One approach involves preventing USB flash drives from being copied or sending them over email. The second one concerns preventing leakage or fraud in which an insider accesses files or databases with harmful intentions. What's the best way to protect your data? It seems obvious that prevention is the best way to solve any problem. In most cases, DCAP (data-centric audit and protection) and DAM (database activity monitoring) is sufficient. Both serve the purpose of protecting data at rest. The following example illustrates the approach we found in the Russian legal system. An employee of the Federal Migration Service in one of the Russian regions was approached by his friend, who asked him to hide information about two offenses in his file in the migrant database. The employee knew that this could be done remotely, accessed the database from home,

In what's likely to be a goldmine for bad actors, personal information associated with approximately 533 million Facebook users worldwide has been leaked on a popular cybercrime forum for free—which was harvested by hackers in 2019 using a Facebook vulnerability. The  leaked data  includes full names, Facebook IDs, mobile numbers, locations, email addresses, gender, occupation, city, country, marital status broken, account creation date, and other profile details broken down by country, with over 32 million records belonging to users in the U.S., 11 million users the U.K., and six million users in India, among others. Also included in the leak are  phone numbers  from Facebook CEO Mark Zuckerberg, and co-founders Chris Hughes, and Dustin Moskovitz, who are the fourth, fifth, and sixth members to have registered on Facebook. Interestingly, it appears that the same phone number is also registered to his name on the privacy-focussed messaging app Signal. "Mark Zuckerberg als

A week after cybersecurity researchers disclosed a flaw in the popular GO SMS Pro messaging app, it appears the developers of the app are silently taking steps to fix the issue from behind the scenes. The  security misstep  made it possible for an attacker to come up with a trivial script to access media files transferred between users, including private voice messages, photos, and videos, stored on an unauthenticated, publicly accessible server. Although the behavior was observed on version 7.91 of GO SMS Pro for Android, the app makers have since released three subsequent updates, two of which (v7.93 and v7.94) were pushed to the Google Play Store after public disclosure of the flaw and Google's removal of the app from the marketplace. Google reinstated the app back to the Play Store on November 23. Now following an analysis of the updated versions, Trustwave researchers said , "GOMO is attempting to fix the issue, but a complete fix is still not available in the app.&
