A malicious Android app with more than 500,000 downloads from the Google Play app store has been found hosting malware that stealthily exfiltrates users' contact lists to an attacker-controlled server and signs up users to unwanted paid premium subscriptions without their knowledge. The latest Joker malware was found in a messaging-focused app named  Color Message  ("com.guo.smscolor.amessage"), which has since been removed from the official app marketplace. In addition, it has been observed simulating clicks in order to generate revenue from malicious ads and connecting to servers located in Russia. Color Message "accesses users' contact list and exfiltrates it over the network [and] automatically subscribes to unwanted paid services," mobile security firm Pradeo  noted .

Cybersecurity researchers took the wraps off yet another instance of Android malware hidden under the guise of legitimate applications to stealthily subscribe unsuspecting users for premium services without their knowledge. In a report published by Check Point research today, the malware — infamously called Joker (or Bread) — has found another trick to bypass Google's Play Store protections: obfuscate the malicious DEX executable inside the application as Base64 encoded strings, which are then decoded and loaded on the compromised device. Following responsible disclosure by Check Point researchers, the 11 apps ( list and hashes here ) in question were removed by Google from the Play Store on April 30, 2020. "The Joker malware is tricky to detect, despite Google's investment in adding Play Store protections," said Check Point 's Aviran Hazum, who identified the new modus operandi of Joker malware.

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a
