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...

Own an Android smartphone? Hackers can secretly install malicious apps, games, and pop-up adverts on your smartphone remotely in order to make large sums of money. Security researchers at Cheetah Mobile have uncovered one of the world's largest and most prolific Trojan families, infecting millions of Android devices around the world. Dubbed Hummer , the notorious mobile trojan stealthily installs malicious apps, games, or even porn apps onto victim's phones and yields its creators more than $500,000 (£375,252) on a daily basis. First discovered in 2014 by Cheetah Mobile, Hummer gained traction in early 2016 when the Trojan family was infecting "nearly 1.4 Million devices daily at its peak" with 63,000 infections occurring daily in China, according to researchers at Cheetah Mobile Security Research Lab. "This Trojan continually pops up ads on victims' phones, which is extremely annoying," researchers wrote in a blog post. "It also pushe...

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...

Facebook users just Beware!! Don't click any porn links on Facebook. Foremost reason is that you have thousands of good porn sites out there, but there's an extra good reason right now. Rogue pornography links on the world's most popular social network have reportedly infected over 110,000 Facebook users with a malware Trojan in just two days and it is still on the rise, a security researcher warned Friday. The Facebook malware disguised as a Flash Player update and spreads itself by posting links to a pornographic video from the Facebook accounts of previously infected users. The malware generally tags as many as 20 friends of the infected user . "In the new technique, which we call it ' Magnet ,' the malware gets more visibility to potential victims by tagging the friends of the victim in the malicious post," said Mohammad Faghani, a senior consultant at PricewaterhouseCoopers, in a mailing list post to the Full Disclosure infosec hangout.  "A tag may...

A Chinese malware campaign called ' Beebus ' specifically targeting the aerospace and defense industries has been uncovered by FireEye security researchers. Beebus is designed to steal information, and begins its infiltration, as so many attacks do, with spear-phishing emails. Operation Beebus very related to Operation Shady RAT and was first detected in April 2011. The attacks carried out by  spear phishing attack and drive-by downloads as a means of infecting end users. malicious Whitepapers or PDFs were mailed to targets and by using known flaws, malware was able install Trojan backdoors on vulnerable systems. The malware communicates with a remote command and control (CnC) server. FireEye discovered the attacks on some of its customers in the aerospace and defence last March and the Vulnerability in the Windows OS known as DLL search order hijacking was used to drops a DLL called ntshrui.DLL in the C:\Windows directory.  It has modules ...
