Unit 42 continuously hunts for new and unique malware samples that match known advanced persistent threat (APT) patterns and tactics. On May 19, one such sample was uploaded to VirusTotal, where it received a benign verdict from all 56 vendors that evaluated it. Beyond the obvious detection concerns, we believe this sample is also significant in terms of its malicious payload, command and control (C2), and packaging.

Severity: High The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation.

Flubot is an Android based malware that has been distributed in the past 1.5 years in Europe, Asia and Oceania affecting thousands of devices of mostly unsuspecting victims. Like the majority of Android banking malware, Flubot abuses Accessibility Permissions and Services in order to steal the victim’s credentials, by detecting when the official banking application is open to show a fake web injection, a phishing website similar to the login form of the banking application. An important part of the popularity of Flubot is due to the distribution strategy used in its campaigns, since it has been using the infected devices to send text messages, luring new victims into installing the malware from a fake website. In this article we detail its development over time and recent developments regarding its disappearance, including new features and distribution campaigns.

The SMS claims that in order to restore mobile data connectivity, the target must install the carrier app and includes a link to download and install this fake app.
