Catelites

There has been one hacking group, which has contributed to the development of Android-based Banking Trojans, and this is the Cron hacking group. They are believed to originate from Russia, and despite the success of their campaigns, which garnered them heaps of cash, they ended up being caught by the Russian law-enforcement authorities in 2017. However, some of their hacking tools are still being propagated online by other ill-minded actors. One of these tools is the Catelites Android Banking Trojan (also known as Catelites Bot). Poses as a Legitimate Application The creators of the Catelites Banking Trojan have made sure to put some effort into making this threat appear as an authentic application. It is likely that the Catelites Trojan is hosted on shady application stores or third-party web pages that host dubious content. In...

Marcher

The Marcher Trojan is a strain of Android malware that has been active since 2013 and is also known under the alias Rahunok. Throughout the years, a number of updates have been introduced to the Marcher project, making it even more threatening. At first, the Marcher Trojan served to collect Google Playstore login credentials. However, with some of the recent upgrades, the Marcher Trojan has also been enabled to access the text messages of the user, thus having the ability to bypass the two-factor authentication that some websites have. Propagation Methods It appears that the main propagation methods involved in the spreading of the Marcher Android Trojan are bogus application downloads, spam text messages and shady application stores.

Peta Ransomware

There are more and more ransomware threats popping up each day as malware experts struggle to study and analyze them. Many cyber crooks choose to spare their efforts, and instead of building a data-locking Trojan from the ground up, they decide to borrow the code of an already established threat and only slightly change it. Propagation and Encryption This is the case of the newly uncovered Peta Ransomware. Once discovered, it was quickly revealed that this threat belongs to the infamous STOP Ransomware family. It is not yet known what propagation methods are the attackers employing. Some speculate that the most commonly used infection vectors may be at play in the spreading of the Peta Ransomware – spam emails containing macro-laced attachments alongside fake software updates and bogus pirated copies of popular applications.

MGS Ransomware

More and more cyber crooks turn to ransomware threats as an easy way to generate a quick buck.

Tiny.z

It is not an unexpected practice for the cybercriminals to sell or rent their hacking tools to other shady individuals online. This is exactly the case of the Tiny.z Android Banking Trojan.

Ares Botnet

The creation of botnets has been a widespread practice in the world of cybercrime. However, with more and more devices becoming 'smart' and thus connected to the Internet, a new niche for exploitation has opened up, and cyber crooks around the world have not failed to notice. This has lead to the creation of botnets, which consist exclusively of IoT (Internet-of-Things) devices. These devices are particularly vulnerable to cyber attacks as they often lack any security measures or have very weak ones in place. Among the most recently detected IoT botnets is the Ares Botnet. Apparently, the creators of the Ares Botnet have been wildly successful as this botnet's activity makes up more than 11% of all IoT botnet activity globally. Can Use Brute-Force to Get Login Credentials The creators of the Ares Botnet propagate their malware via...

Necro

The Android OS takes up about 88% (according to a Statista report) of the global market share, making it the most popular OS for smartphones with a huge leading margin. The largest application platform for Android is the Google Play Store. Having in mind the sheer number of Android devices in the world and the countless applications tailored for them it is easy to see how the Google Play Store is struggling to keep off all the potentially malicious apps which may end up on their platform. Among these malicious applications that have slipped between the cracks is the 'CamScanner' app, which has managed to get over 100,000 downloads. Its software is supposed to be able to convert a photo of a document into a PDF file which the user will be able to edit. New Update Contains a Trojan The free variant of the application displays ads, which...

Able to Bypass Two-Factor Authentication Many banking portals and applications have employed two-factor authentication to guarantee maximum security to their users. However, cleverly designed banking Trojans like the Hqwar threat are...
