Beware of Fake Telegram Messenger App Hacking PCs with Purple Fox Malware

Beware of Fake Telegram Messenger App Hacking PCs with Purple Fox Malware

Jan 04, 2022
Trojanized installers of the Telegram messaging application are being used to distribute the Windows-based Purple Fox backdoor on compromised systems. That's according to new research published by Minerva Labs, describing the attack as different from intrusions that typically take advantage of legitimate software for dropping malicious payloads. "This threat actor was able to leave most parts of the attack under the radar by separating the attack into several small files, most of which had very low detection rates by [antivirus] engines, with the final stage leading to Purple Fox rootkit infection," researcher Natalie Zargarov  said . First discovered in 2018, Purple Fox comes with rootkit capabilities that allow the malware to be planted beyond the reach of security solutions and evade detection. A March 2021 report from Guardicore  detailed  its worm-like propagation feature, enabling the backdoor to spread more rapidly. Then in October 2021, Trend Micro researche
Signal is Most Secure Messenger, 'Useless Data' Obtained by FBI Proves It All

Signal is Most Secure Messenger, 'Useless Data' Obtained by FBI Proves It All

Oct 04, 2016
Do you trust your messaging app even though it uses end-to-end encryption? As I previously said end-to-end encryption doesn't mean that your messages are secure enough to hide your trace. It's because most of the messaging apps still record and store a lot of metadata on your calls and messages that could reveal some of your personal information including dates and durations of communication, as well as the participants' phone numbers. Apple's iMessage app is the most recent and best example of this scenario. Just recently it was reported that the company stores a lot of information about its end-to-end encrypted iMessage, that could reveal your contacts and location, and even share this data with law enforcement via court orders. But if you are using open source end-to-end encrypted Signal   app, you are on the safer side. Trust me! As we previously reported that the Signal app, which is widely considered the most secure of all other encrypted messaging a

Researcher Found TextSecure Messenger App Vulnerable to Unknown Key-Share Attack

Nov 03, 2014
Do you use  TextSecure Private Messenger  for your private conversations? If yes, then Are you sure you are actually using a Secure messaging app? TextSecure , an Android app developed by Open WhisperSystems , is completely open-source and claims to support end-to-end encryption of text messages. The app is free and designed by keeping privacy in mind. However, while conducting the first audit of the software, security researchers from Ruhr University Bochum found that the most popular mobile messaging app is open to an Unknown Key-Share attack . After Edward Snowden revealed state surveillance programs conducted by the National Security Agency, and meanwhile when Facebook acquired WhatsApp , TextSecure came into limelight and became one of the best alternatives for users who want a secure communication. " Since Facebook bought WhatsApp , instant messaging apps with security guarantees became more and more popular ," the team wrote in the paper titled,
Skype Finally Adds End-to-End Encryption for Private Conversations

Skype Finally Adds End-to-End Encryption for Private Conversations

Jan 12, 2018
Good news for Skype users who are concerned about their privacy. Microsoft is collaborating with popular encrypted communication company Signal to bring end-to-end encryption support to Skype messenger. End-to-end encryption assured its users that no one, not even the company or server that transmits the data, can decrypt their messages. Signal Protocol is an open source cryptographic protocol that has become an industry-wide standard—which is used in  Facebook Messenger , Whatsapp , and Google Allo for secure messaging. Dubbed Private Conversations , the new feature which is about to be introduced in Skype will offer end-to-end encryption for audio calls, text, and multimedia messages like videos and audio files. "Skype Private Conversations give you enhanced security through end-to-end encryption with an additional layer of security for conversations between you and your friends and family," the company announced .  "Private Conversations can only be betwe

Lookalike Telegram and WhatsApp Websites Distributing Cryptocurrency Stealing Malware

Mar 17, 2023 Cryptocurrency / Mobile Security
Copycat websites for instant messaging apps like Telegram and WhatApp are being used to distribute trojanized versions and infect Android and Windows users with cryptocurrency clipper malware . "All of them are after victims' cryptocurrency funds, with several targeting cryptocurrency wallets," ESET researchers Lukáš Štefanko and Peter Strýček said in a new analysis. While the first instance of clipper malware on the Google Play Store dates back to 2019, the development marks the first time Android-based clipper malware has been built into instant messaging apps. "Moreover, some of these apps use optical character recognition (OCR) to recognize text from screenshots stored on the compromised devices, which is another first for Android malware," the Slovak cybersecurity firm added. The attack chain begins with unsuspecting users clicking on fraudulent ads on Google search results that lead to hundreds of sketchy YouTube channels, which then direct them

Facebook Helps FBI to shuts down Butterfly botnet theft $850 millions

Dec 12, 2012
The U.S. Department of Justice said on Tuesday that they've arrested 10 suspects from from Bosnia and Herzegovina, Croatia, Macedonia, New Zealand, Peru, the United Kingdom, and the United States involved in a global botnet operation that infected more than 11 million systems. The ring is said to have caused more than $850m in losses in one of the largest cyber crime hauls in history. Officials said international cyber crime rings linked to Butterfly (aka Mariposa) botnet, first discovered in December 2008 and shut down a year later, infected over 12 million PCs worldwide and was spread primarily through file-sharing and instant messaging attacks. It also harvested financial information from over 800,000 victims. FBI said , " Facebook's security team provided assistance to law enforcement throughout the investigation by helping to identify the root cause, the perpetrators, and those affected by the malware. Yahos targeted Facebook users from 2010 to October 2012, and security sy

New Variant of Emotet Banking Malware targets German Users

Jan 07, 2015
A new Spam email campaign making the rounds in Germany are delivering a new variant of a powerful banking malware , a financial threat designed to steal users' online banking credentials, according to security researchers from Microsoft. The malware, identified as Emotet , was first spotted last June by security vendors at Trend Micro. The most standout features of Emotet is its network sniffing ability , which enables it to capture data sent over secured HTTPS connections by hooking into eight network APIs, according to Trend Micro. Microsoft has been monitoring a new variant of Emotet banking malware , Trojan:Win32/Emotet.C , since November last year. This new variant was sent out as part of a spam email campaign that peaked in November. Emotet has been distributed through spam messages, which either contain a link to a website hosting the malware or a PDF document icon that is actually the malware.

A Single-Character Message Can Crash Any Apple iPhone, iPad Or Mac

Feb 16, 2018
Only a single character can crash your iPhone and block access to the Messaging app in iOS as well as popular apps like WhatsApp, Facebook Messenger, Outlook for iOS, and Gmail. First spotted by Italian Blog Mobile World, a potentially new severe bug affects not only iPhones but also a wide range of Apple devices, including iPads, Macs and even Watch OS devices running the latest versions of their operating software. Like previous 'text bomb' bug, the new flaw can easily be exploited by anyone, requiring users to send only a single character from Telugu—a native Indian language spoken by about 70 million people in the country. Once the recipient receives a simple message containing the symbol or typed that symbol into the text editor, the character immediately instigates crashes on iPhones, iPads, Macs, Apple Watches and Apple TVs running Apple's iOS Springboard. Apps that receive the text bomb tries to load the character, but fails and refuses to function prope

30 Million Facebook Accounts Were Hacked: Check If You're One of Them

Oct 13, 2018
Late last month Facebook announced its worst-ever security breach that allowed an unknown group of hackers to steal secret access tokens for millions of accounts by taking advantage of a flaw in the 'View As' feature. At the time of the initial disclosure, Facebook estimated that the number of users affected by the breach could have been around 50 million, though a new update published today by the social media giant downgraded this number to 30 million. Out of those 30 million accounts, hackers successfully accessed personal information from 29 million Facebook users, though the company assured that the miscreants apparently didn't manage to access any third-party app data . Here's How Facebook Classified the Stolen Data: Facebook vice president of product management Guy Rosen published a new blog post  Friday morning to share further details on the massive security breach, informing that the hackers stole data from those affected accounts, as follows: For about 1

Spammers using Facebook Messenger to Spread Locky Ransomware

Nov 21, 2016
If you came across any Facebook Message with an image file (exactly .SVG file format) send by any of your Facebook friends, just avoid clicking it. An ongoing Facebook spam campaign is spreading malware downloader among Facebook users by taking advantage of innocent-looking SVG image file to infect computers. If clicked, the file would eventually infect your PC with the nasty Locky Ransomware , a family of malware that has quickly become one of the favorite tools among criminals due to its infecting capabilities. Discovered by malware researcher Bart Blaze , the attack campaign uses Facebook Messenger to spread a malware downloader called Nemucod that takes the form of .SVG image files. Why SVG file? Hackers considered SVG (or Scalable Vector Graphics) files for spreading the malware downloader, because SVG has the ability to contain embedded content such as JavaScript, and can be opened in a modern web browser. Crooks added their malicious JavaScript code right inside th
