Campaigns spreading ERMAC malware

A team of Cyble researchers recently discovered a mass phishing campaign aimed at spreading the ERMAC banking trojan. The infection method is based on downloading fake apps that impersonate Google Wallet, PayPal, Snapchat, and others.

These fake apps are downloaded from fake domains with websites that impersonate some of the most popular Android markets. These impersonations also include fake domains based on the companies allegedly distributing the apps.

Once these fake apps are executed, the ERMAC malware proceeds to steal data such as contact and SMS information, as well as a list of apps in use by the device. Phishing pages are displayed on the victim’s screen via that latter function, which in turn sends the collected data to the malware’s Command & Control via POST requests.

Critical vulnerability in OpenSSL announced

The OpenSSL Project team has announced that it will release a new version of OpenSSL, version 3.0.7 on November 1st, which will include a security patch that has been classified as critical.

While no details have been released of the serious vulnerability that will be fixed in this release beyond the fact that it does not affect versions prior to 3.0, its mere existence has caused concern as it is the first critical vulnerability to be announced by OpenSSL since 2016.

Although the developers have announced the deployment of the new version and the bug in advance so that users have time to take inventories and prepare their systems, OpenSSL does not believe that this will be enough for attackers to discover the vulnerability, as Mark J. Cox, a member of the team, has stated.

Drinik: Android banking trojan re-emerges with advanced capabilities

Analysts at Cyble have detected a new version of the Drinik banking malware, targeting Android systems, and currently targeting 18 banking institutions in India.

According to Cyble’s report, the trojan poses as the country’s official tax administration app (iAssist) to steal victims’ personal information and banking credentials. Once installed on the victim’s device, the application requests permissions to write to external storage, receive, read and send SMS, and read the call log.

It will also request permission to make use of Android’s accessibility service, which will disable Google Play Protect and enable the malware to perform navigation gestures, record the screen and capture keystrokes and user credentials, displaying the legitimate Indian income tax site in the app.

As an end goal, Drinik redirects victims to an Income Tax Department phishing website where, under the guise of a refund in their favour, it will ask the user for their financial information, including account number, credit card number, CVV and PIN.

Drinik has been known since 2016 and has been evolving continuously improving its capabilities and targeting mass audiences, such as Indian taxpayers and bank customers in this case.
