A new phishing attack is leveraging Facebook Messenger to propagate messages with malicious attachments from a "swarm of fake and hijacked personal accounts" with the ultimate goal of taking over the targets' Business accounts. "Originating yet again from a Vietnamese-based group, this campaign uses a tiny compressed file attachment that packs a powerful Python-based stealer dropped in a multi-stage process full of simple yet effective obfuscation methods," Guardio Labs researcher Oleg Zaytsev  said  in an analysis published over the weekend. In these attacks, dubbed MrTonyScam, potential victims are sent messages that entice them into clicking on the RAR and ZIP archive attachments, leading to the deployment of a dropper that fetches the next-stage from a GitHub or GitLab repository. This payload is another archive file that contains a CMD file, which, in turn, harbors an obfuscated Python-based stealer to exfiltrate all cookies and login credentials from d...

There are several encrypted messaging apps for mobile and desktop platforms that shipped with "The Most Secure" tagline but ends up in de-anonymizing the real identity of its users in some or the other way. In fact, very few encrypted messaging apps available today deal with the core problem of Metadata .  The majority of apps offer end-to-end encryption that kept the content of your messages away from prying eyes, but your metadata will still be accessible to them, which is enough to know who you really are, and who you're talking to. But, one messenger app stands out of the crowd by providing superb anonymity to its users, and it is dubbed as " Ricochet ." Ricochet is a peer-to-peer instant messaging system available for Windows, Mac, and Linux and you can trust it as the app has already cleared its first professional security audit carried out by cyber security company NCC Group . What's so Promising about Ricochet? Unlike ...

Cybersecurity researchers over the weekend disclosed new security risks associated with link previews in popular messaging apps that cause the services to leak IP addresses, expose links sent via end-to-end encrypted chats, and even unnecessarily download gigabytes of data stealthily in the background. "Links shared in chats may contain private information intended only for the recipients," researchers Talal Haj Bakry and Tommy Mysk  said . "This could be bills, contracts, medical records, or anything that may be confidential." "Apps that rely on servers to generate link previews may be violating the privacy of their users by sending links shared in a private chat to their servers." Generating Link Previews at the Sender/Receiver Side Link previews are a common feature in most chat apps, making it easy to display a visual preview and a brief description of the shared link. Although apps like  Signal  and  Wire  give users the option to turn on/off l...

Meta on Tuesday said it's launching new tools to protect Messenger and WhatsApp users from potential scams. To that end, the company said it's introducing new warnings on WhatsApp when users attempt to share their screen with an unknown contact during a video call so as to prevent them from giving away sensitive information like bank details or verification codes. On Messenger, users can opt to enable a setting called "Scam detection" by navigating to Privacy & safety settings. Once it's turned on, users are alerted when they receive a potentially suspicious message from an unknown connection that may contain signs of a scam. "Because detection happens on your device, chats with end-to-end encryption stay secure," Meta said in a support document. "If you’re notified that a chat may contain signs of a scam, we'll ask if you'd like to send recent messages you received to AI review. Messages that are shared with AI are no longer end-...

Security, trust, and stability — once the pillars of our digital world — are now the tools attackers turn against us. From stolen accounts to fake job offers, cybercriminals keep finding new ways to exploit both system flaws and human behavior. Each new breach proves a harsh truth: in cybersecurity, feeling safe can be far more dangerous than being alert. Here’s how that false sense of security was broken again this week. ⚡ Threat of the Week Newly Patched Critical Microsoft WSUS Flaw Comes Under Attack — Microsoft released out-of-band security updates to patch a critical-severity Windows Server Update Service (WSUS) vulnerability that has since come under active exploitation in the wild. The vulnerability in question is CVE-2025-59287 (CVSS score: 9.8), a remote code execution flaw in WSUS that was originally fixed by the tech giant as part of its Patch Tuesday update published last week. According to Eye Security and Huntress, the security flaw is being weaponized to drop a .N...

"Respect for your privacy is coded into our DNA," opens WhatsApp's  privacy policy . "Since we started WhatsApp, we've aspired to build our Services with a set of strong privacy principles in mind." But come February 8, 2021, this opening statement will no longer find a place in the policy. The Facebook-owned messaging service is alerting users in India of an update to its  terms of service  and  privacy policy  that's expected to go into effect next month. The "key updates" concern how it processes user data, "how businesses can use Facebook hosted services to store and manage their WhatsApp chats," and "how we partner with Facebook to offer integrations across the Facebook Company Products." The mandatory changes allow WhatsApp to  share  more user data with other Facebook companies, including account registration information, phone numbers, transaction data, service-related information, interactions on the platform,...

If you receive an image file sent by someone, even your friend, on your Facebook Messenger, LinkedIn or any other social media platform, just DO NOT CLICK ON IT. Even JPG image file could eventually infect your computer with the infamous Locky Ransomware . Earlier this week, we reported a new attack campaign that used Facebook Messenger to spread Locky Ransomware via .SVG image files, although Facebook denied this was the case. Now, researchers have discovered that the ongoing spam campaign is also using boobytrapped .JPG image files in order to download and infect users with the Locky Ransomware via Facebook, LinkedIn, and other social networking platforms. Security researchers from Israeli security firm Check Point have reportedly discovered how cyber criminals are hiding malware in image files, and how they are executing the malware code within these images to infect social media users with Locky variants. According to researchers, malware authors have discovered secu...

Malwares are getting updated during the age of social networking. FortiGuard Labs researchers have discovered a new malware called ' Rodpicom Botnet ' that spreads via messaging applications such as Skype and MSN Messenger. Dubbed W32/Rodpicom.A - Rodpicom Botnet sends a message to the victim with a link to a malicious site that leads to downloadable content. When the user clicks the link, the attack downloads another strain of malware, known as Dorkbot . Once the target machine is infected, it checks to see if the victim is using any messaging applications such as Skype or MSN Messenger.  It is revealed that, the malware employs new stealth tactics, including an exception handling technique that generates its own error to dodge analysis and relies on an anti-emulator that attacks the heuristic-scanning capabilities in antivirus software and enables its code to jump around several hundred times. The malware is enough smart to checks the language of the installed operating...

The North Korea-linked  Kimsuky hacking group  has been attributed to a new social engineering attack that employs fictitious Facebook accounts to targets via Messenger and ultimately delivers malware. "The threat actor created a Facebook account with a fake identity disguised as a public official working in the North Korean human rights field," South Korean cybersecurity company Genians  said  in a report published last week. The multi-stage attack campaign, which impersonates a legitimate individual, is designed to target activists in the North Korean human rights and anti-North Korea sectors, it noted. The approach is a departure from the typical email-based spear-phishing strategy in that it leverages the social media platform to approach targets through Facebook Messenger and trick them into opening seemingly private documents written by the persona. The decoy documents, hosted on OneDrive, is a Microsoft Common Console document that masquerades ...

Luring users on social media to visit lookalike version of popular websites that pop-up a legitimate-looking Chrome extension installation window is one of the most common modus operandi of cybercriminals to spread malware. Security researchers are again warning users of a new malware campaign that has been active since at least March this year and has already infected more than 100,000 users worldwide. Dubbed Nigelthorn, the malware is rapidly spreading through socially engineered links on Facebook and infecting victims’ systems with malicious browser extensions that steal their social media credentials, install cryptocurrency miners, and engage them in click fraud. The malware was pushed through at least seven different Chrome browser extensions—all were hosted on Google's official Chrome Web Store. These malicious Chrome browser extensions were first discovered by researchers at cybersecurity firm Radware, after a "well-protected network" of one of its custo...

Pretty good news for privacy-oriented people! BitTorrent unwraps its new instant messaging program that doesn’t store your metadata and helps you with encrypted communication to keep your online conversations private, whether its voice or text communications. BitTorrent named its Online chat service as " Bleep ", a decentralised peer-to-peer voice and text communications platform that offers end-to-end encryption, therefore is completely safe from the prying eyes. In order to spread users’ voice and text conversations, Bleep make use of the BitTorrent distributed network rather than a centralised server. Unlike Skype or Google Hangouts, Bleep comes with with a completely decentralized design, giving you extremely strong anonymity. WHY BLEEP? " We never see your messages or metadata, " said Jaehee Lee, the senior product manager for Bleep, in a blog post announcing the new app on Wednesday. " As far as we're concerned, anything you say is 'bleep'...

If you rely on messaging apps to remain in contact with your family members and friends, then you may have to switch back to old-fashioned text messaging service in matter of weeks due to a new law currently going through Parliament. WhatsApp and Facebook Messenger to Ban in UK The popular messaging applications, including WhatsApp, Snapchat, iMessage and Facebook Messenger, could all potentially be banned in the UK under the controversial ' Snoopers Charter '. The Investigatory Powers Bill -- the so-called Snoopers Charter -- mentioned in the 2015 Queen's Speech , would allow UK government to eradicate instant messaging apps that refuse to switch off end-to-end encryption from their services. Earlier this year in light of the Charlie Hebdo shootings in Paris, Prime Minister David Cameron hinted at the crackdown when he claimed that he would ban encrypted messaging apps like Snapchat, WhatsApp and Messenger unless they didn't comply with new surve...

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...

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...

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,...

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...

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 ...
