Hacking Facebook users just from chat box using multiple vulnerabilities

Apr 17, 2013
Nir Goldshlager , Founder/CEO at Break Security known for finding serious flaws in Facebook once again on The Hacker News for  sharing his new finding i.e Stored Cross-site Scripting (XSS) in Facebook Chat, Check In and Facebook Messenger. Stored Cross-site Scripting ( XSS ) is the most dangerous type of Cross Site Scripting. Web applications where the injected code is permanently stored on the target servers, such as in a database, in a message forum, visitor log, comment field, etc 1.) Stored XSS In Facebook Chat: This vulnerability can be used to conduct a number of browser-based attacks including, Hijacking another user's browser, Capturing sensitive information viewed by application users, Malicious code is executed by the user's browser etc. When a user starts a new message within Facebook that has a link inside, a preview GUI shows up for that post. The GUI is used for presenting the link post using a parameter i.e  attachment[params][title],attac

YAHOO! Now Encrypts Everything; Encrypted Yahoo Messenger Coming Soon

Apr 03, 2014
ON HIGH-PRIORITY YAHOO! is finally rolling out encryption implementation over their site and services in order to protect users. Yahoo is rapidly becoming one of the most aggressive supporters of encryption, as in January this year Yahoo enabled the HTTPS connections by default, that automatically encrypts the connections between users and its email service. November last year, Yahoo revealed plans to encrypt all information that moves between its data centers and finally from 31st March Yahoo has taken another leap in user-data protection through the deployment of new encryption technologies. NSA TARGET LIST -  GMAIL, YAHOO, ... many more. Last year, It was revealed by  Edward Snowden  that under MUSCULAR program , the spy agency NSA was infiltrating the private data links between Google and Yahoo data centers. After finding themselves in the NSA's target list, Yahoo! and Google forced to think hard about the security and privacy of its users. Google had replied back
Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Apr 15, 2024Active Directory / Attack Surface
To minimize the risk of privilege misuse, a trend in the privileged access management (PAM) solution market involves implementing just-in-time (JIT) privileged access. This approach to  privileged identity management  aims to mitigate the risks associated with prolonged high-level access by granting privileges temporarily and only when necessary, rather than providing users with continuous high-level privileges. By adopting this strategy, organizations can enhance security, minimize the window of opportunity for potential attackers and ensure that users access privileged resources only when necessary.  What is JIT and why is it important?   JIT privileged access provisioning  involves granting privileged access to users on a temporary basis, aligning with the concept of least privilege. This principle provides users with only the minimum level of access required to perform their tasks, and only for the amount of time required to do so. One of the key advantages of JIT provisioning
Facebook Adds End-to-End Encryption for Audio and Video Calls in Messenger

Facebook Adds End-to-End Encryption for Audio and Video Calls in Messenger

Aug 14, 2021
Facebook on Friday said it's extending end-to-end encryption (E2EE) for voice and video calls in Messenger, along with testing a new opt-in setting that will turn on end-to-end encryption for Instagram DMs. "The content of your messages and calls in an end-to-end encrypted conversation is protected from the moment it leaves your device to the moment it reaches the receiver's device," Messenger's Ruth Kricheli  said  in a post. "This means that nobody else, including Facebook, can see or listen to what's sent or said. Keep in mind, you can report an end-to-end encrypted message to us if something's wrong." The social media behemoth said E2EE is becoming the industry standard for improved privacy and security. It's worth noting that the company's flagship messaging service gained support for E2EE in text chats in 2016, when it added a " secret conversation " option to its app, while communications on its sister platform What

Signal Messenger Bug Lets Callers Auto-Connect Calls Without Receivers' Interaction

Signal Messenger Bug Lets Callers Auto-Connect Calls Without Receivers' Interaction

Oct 04, 2019
Almost every application contains security vulnerabilities, some of which you may find today, but others would remain invisible until someone else finds and exploits them—which is the harsh reality of cybersecurity and its current state. And when we say this, Signal Private Messenger —promoted as one of the most secure messengers in the world—isn't any exception. Google Project Zero researcher Natalie Silvanovich discovered a logical vulnerability in the Signal messaging app for Android that could allow malicious caller to force a call to be answered at the receiver's end without requiring his/her interaction. In other words, the flaw could be exploited to turn on the microphone of a targeted Signal user's device and listen to all surrounding conversations. However, the Signal vulnerability can only be exploited if the receiver fails to answer an audio call over Signal, eventually forcing the incoming call to be automatically answered on the receiver's device
Facebook Starts WhatsApp Integration for Android Users

Facebook Starts WhatsApp Integration for Android Users

Apr 06, 2015
Is Facebook planning to integrate WhatsApp Messenger into its ' Facebook for Android ' app? Yes, this might be possible soon. According to latest rumours, Facebook is reportedly working on it. The social network giant, Facebook has begun testing a new feature in its Facebook app for Android that includes the first integration of WhatsApp Messenger, according to a blogger. WHATSAPP INTEGRATION INTO FACEBOOK APP According to this update, a year after of acquiring WhatsApp Messenger, Facebook has only added a 'Send' button with the WhatsApp icon. This WhatsApp ' send ' will work as part of the status actions options that appear under each status update. It means that Facebook for Android users soon may have this particular version of Facebook app with a dedicated WhatsApp button that would allow an Android user to share posts, status and anything else directly through WhatsApp by just clicking the Share button. If rumours are true, th
Telegram Calling Feature Leaks Your IP Addresses—Patch Released

Telegram Calling Feature Leaks Your IP Addresses—Patch Released

Oct 01, 2018
The desktop version of the security and privacy-focused, end-to-end encrypted messaging app, Telegram , has been found leaking both users' private and public IP addresses by default during voice calls. With 200 million monthly active users as of March 2018, Telegram promotes itself as an ultra-secure instant messaging service that lets its users make end-to-end encrypted chat and voice call with other users over the Internet. Security researcher Dhiraj Mishra uncovered a vulnerability (CVE-2018-17780) in the official Desktop version of Telegram (tdesktop) for Windows, Mac, and Linux, and Telegram Messenger for Windows apps that was leaking users' IP addresses by default during voice calls due to its peer-to-peer (P2P) framework. To improve voice quality, Telegram by default uses a P2P framework for establishing a direct connection between the two users while initiating a voice call, exposing the IP addresses of the two participants. Telegram Calls Could Leak Your
Facebook Introduces New Features for End-to-End Encrypted Messenger App

Facebook Introduces New Features for End-to-End Encrypted Messenger App

Jan 24, 2023 Encryption / Privacy
Meta Platforms on Monday announced that it has started to expand global testing of end-to-end encryption ( E2EE ) in Messenger chats by default. "Over the next few months, more people will continue to see some of their chats gradually being upgraded with an extra layer of protection provided by end-to-end encryption," Meta's Melissa Miranda  said . The social media behemoth said it intends to notify users in select individual chat threads as the security feature is enabled, while emphasizing that the process of choosing and upgrading the conversations to support E2EE is random. "It's designed to be random so that there isn't a negative impact on our infrastructure and people's chat experience," Miranda further explained. Along with flipping the switch on E2EE, Meta has also added more features into its encrypted chat experience, including support for themes, custom emojis and reactions, group profile photos, link previews, and active status.

Sometimes I receive emails from our readers who wanted to know how to hack Facebook account , but just to delete some of their messages they have sent to their friends or colleagues mistakenly or under wrong circumstances like aggression. How to hack a Facebook account? It is probably the biggest "n00b" question you will see on the Internet. The solution for this query is hard to find — but recently researchers have shown that how you can modify or alter your messages once you have pressed the SEND button in Facebook Messenger. According to the researcher  Roman Zaikin  from cyber security firm Check Point , a simple HTML tweak can be used to exploit Facebook online chat as well as its Messenger app, potentially allowing anyone to modify or delete any of his/her sent message, photo, file, and link. Though the bug is simple, it could be exploited by malicious users to send a legitimate link in a Facebook chat or group chat, and later change it to a malicious link t

Facebook Fired An Intern After He Exposes How to Track Users' Location

Aug 14, 2015
Previously, we posted about a privacy issue in Facebook messenger ; Aran Khanna , a Harvard University student, discovered ' A Marauder's Map ' that could sense and give the geolocations of your friends on the messenger. Khanna had received an opportunity to work as an intern for Facebook… …But destiny had planned something else for him, as after publicly stating the risk associated with the app; Facebook withdrew his candidature as a summer intern. Why Facebook Fired Him? Khanna himself confessed to be an avid user of the Facebook Messenger app , as it is an integral part of his social life. However, one day, while going through his chat history he found that a location is attached to each message he has sent and received from his device. Also, the location is shared with the ' power of default ' even if you choose to turn the location sharing option off. This made him look for the complete inside story, which brought him to a strange thing while writing the
WhatsApp 'Delete for Everyone' Doesn't Delete Media Files Sent to iPhone Users

WhatsApp 'Delete for Everyone' Doesn't Delete Media Files Sent to iPhone Users

Sep 16, 2019
Mistakenly sent a picture to someone via WhatsApp that you shouldn't have? Well, we've all been there, but what's more unfortunate is that the 'Delete for Everyone' feature WhatsApp introduced two years ago contains an unpatched privacy bug, leaving its users with false sense of privacy. WhatsApp and its rival Telegram messenger offer "Delete for Everyone," a potentially life-saving feature on which millions of people today rely to escape the awkwardness of mistakenly sending messages / pictures / videos to the wrong person. As the name indicates, the ' Delete for Everyone ' feature is intended to unsend mistakenly sent inappropriate messages—including text, photos and videos—from the recipient's phone, or from the phones of all members of a group. In the case of WhatsApp, the feature is only available within 1 hour, 8 minutes, and 16 seconds of sending a message you want to delete, which is fine and a fair use case. However, it tur

Vietnamese Hackers Deploy Python-Based Stealer via Facebook Messenger

Sep 11, 2023 Malware / Social Media
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
Ricochet — Most Secure Peer-to-Peer Encrypted Messenger that Sends No Metadata

Ricochet — Most Secure Peer-to-Peer Encrypted Messenger that Sends No Metadata

Feb 23, 2016
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 .

Experts Warn of Privacy Risks Caused by Link Previews in Messaging Apps

Experts Warn of Privacy Risks Caused by Link Previews in Messaging Apps

Oct 26, 2020
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
