The Russian Interior Ministry announced on Monday the arrest of 20 individuals from a major cybercriminal gang that had stolen nearly $900,000 from bank accounts after infecting over one million Android smartphones with a mobile Trojan called "CronBot." Russian Interior Ministry representative Rina Wolf said the arrests were part of a joint effort with Russian IT security firm Group-IB that assisted the massive investigation. The collaboration resulted in the arrest of 16 members of the Cron group in November 2016, while the last active members were apprehended in April 2017, all living in the Russian regions of Ivanovo, Moscow, Rostov, Chelyabinsk, and Yaroslavl and the Republic of Mari El. Targeted Over 1 Million Phones — How They Did It? Group-IB first learned of the Cron malware gang in March 2015, when the criminal gang was distributing the Cron Bot malware disguised as Viber and Google Play apps. The Cron malware gang abused the popularity of SMS-banking ...

Here's some bad news for Android users again. Certain low-cost Android smartphones and tablets are shipped with malicious firmware, which covertly gathers data about the infected devices, displays advertisements on top of running applications and downloads unwanted APK files on the victim's devices. Security researchers from Russian antivirus vendor Dr.Web have discovered two types of downloader Trojans that have been incorporated in the firmware of a large number of popular Android devices operating on the MediaTek platform, which are mostly marketed in Russia. The Trojans, detected as Android.DownLoader.473.origin and Android.Sprovider.7 , are capable of collecting data about the infected devices, contacting their command-and-control servers, automatically updating themselves, covertly downloading and installing other apps based on the instructions it receives from their server, and running each time the device is restarted or turned on. The list of Android devic...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Here's some bad news for Android users again. Nearly 3 Million Android devices worldwide are vulnerable to man-in-the-middle (MITM) attacks that could allow attackers to remotely execute arbitrary code with root privileges, turning over full control of the devices to hackers. According to a new report from security rating firm BitSight, the issue is due to a vulnerability in the insecure implementation of the OTA (Over-the-Air) update mechanism used by certain low-cost Android devices, including BLU Studio G from US-based Best Buy. Backdoor/Rootkit Comes Pre-installed The vulnerable OTA mechanism, which is associated with Chinese mobile firm Ragentek Group, contains a hidden binary — resides as /system/bin/debugs — that runs with root privileges and communicates over unencrypted channels with three hosts. According to the researchers, this privileged binary not only exposes user-specific information to MITM attackers but also acts as a rootkit, potentially allowing ...

Do you own an Android smartphone? You could be one of those 700 Million users whose phone is secretly sending text messages to China every 72 hours. You heard that right. Over 700 Million Android smartphones contain a secret 'backdoor' that surreptitiously sends all your text messages, call log, contact list, location history, and app data to China every 72 hours. Security researchers from Kryptowire discovered the alleged backdoor hidden in the firmware of many budget Android smartphones sold in the United States, which covertly gathers data on phone owners and sends it to a Chinese server without users knowing. First reported on by the New York Times on Tuesday, the backdoored firmware software is developed by China-based company Shanghai AdUps Technology, which claims that its software runs updates for more than 700 Million devices worldwide. Infected Android Smartphone WorldWide Moreover, it is worth noting that AdUps provides its software to much larger ha...

A dangerous backdoor has been discovered in the MediaTek processor that could be exploited to hack Android devices remotely. MediaTek is a Taiwan-based hardware company that manufacture hardware chips and processor used in the smartphones and tablets. The backdoor was discovered by security researcher Justin Case , who already informed MediaTek about the security issue via Twitter, as the chipset manufacturer had no proper vulnerability reporting mechanism in place. The vulnerability is apparently due to a debug tool that was opened up for carriers to test the device on their networks, but unfortunately, it was left open in the shipped devices, thus leaving the serious backdoor open to hackers. If exploited, the debug feature could allow hackers to compromise personal data of an Android device, including user's private contacts, messages, photos, videos and other private data. MediaTek acknowledged the issue, saying "We are aware of this issue, and it has bee...
