CA security finds Android Trojan which records phone calls A new Android Trojan is capable of recording phone conversations, according to a CA security researcher . The trojan is triggered when the Android device places or receives a phone call. It saves the audio file and related information to the phone's microSD card, and includes a configuration file with information on a remote server and settings used by the trojan. The malware also " drops a 'configuration' file that contains key information about the remote server and the parameters ," CA security researcher Dinesh Venkatesan writes in a blog, perhaps suggesting that the recorded calls can be uploaded to a server maintained by an attacker. According to the post, the trojan presents itself as an " Android System Message " that requires users to press an "Install" button for it to insert itself in the phone.

The Dridex banking trojan that is widely being used by cyber criminals to distribute malware onto users' machines has now been found distributing a security software. A portion of the Dridex banking Trojan botnet may have been hacked or compromised by an unknown Whitehat Hacker, who replaced the malicious links with  Avira Antivirus  installers. What is Dridex Banking Trojan? How it Works? Dridex malware – also known as Bugat and Cridex – is believed to have been created by cyber criminals in Eastern Europe in an effort to harvest online banking details. Even after a high-profile takedown operation in late 2015, the Dridex botnet seems to be active again. The Dridex virus typically distributes itself through spam messages or emails that include malicious attachments, most often a Microsoft Office file or Word document integrated with malicious macros.

Mac trojan poses as PDF to open botnet backdoor There's another Mac OS X Trojan out in the wild, and it might be heading your way.If you open the file, which could appear as an emailed attachment or as a Web link, the document, written in traditional Chinese ideograms, does indeed display. But a Trojan silently installs itself in the background as you try to sort out centuries-old territorial claims.The Trojan doesn't really do anything yet. But F-Secure, the Finnish security firm that discovered it, notes that it lays the groundwork for much more sophisticated attacks against Macs. The malware in question has been identified as Trojan-Dropper:OSX/Revir.A, which installs a backdoor, Backdoor:OSX/Imuler.A, onto the user's Mac. Currently, however, the backdoor doesn't communicate with anything. The command-and-control center for this particular malware is apparently a bare Apache installation, which has been sitting at its current domain since May of this year. Beca
