Unpacking Slack Hacks: 6 Ways to Protect Sensitive Data with Secure Collaboration

Unpacking Slack Hacks: 6 Ways to Protect Sensitive Data with Secure Collaboration

Aug 26, 2024 Data Security / Compliance
Nowadays, sensitive and critical data is traveling in everyday business channels that offer only the basic level of security and encryption, and companies are often oblivious to the risk. A case in point: Disney suffered a devastating data leak by a hacktivist group known as NullBulge that got hold of over 1.2 terabytes of data from Disney's internal Slack messaging channels. The breach exposed sensitive information, including: details about unreleased projects, computer code, login details and passwords, and Intellectual Property (IP) and corporate secrets. Slack breaches have also impacted companies like Uber, Rockstar, and Electronic Arts (EA). Cisco Webex used by the German Bundeswehr leaked data from hundreds of meetings, some classified. Outlook was breached by Chinese hackers last year. We have nothing against any of the tools above. They are all great collaboration tools. However, just like companies don't allow developers to use just any old tool to push code to p...
Signal Introduces Usernames, Allowing Users to Keep Their Phone Numbers Private

Signal Introduces Usernames, Allowing Users to Keep Their Phone Numbers Private

Feb 21, 2024 Secure Communication / Anonymity
End-to-end encrypted (E2EE) messaging app Signal said it's piloting a new feature that allows users to create unique usernames (not to be confused with profile names) and keep the phone numbers away from prying eyes. "If you use Signal, your phone number will no longer be visible to everyone you chat with by default," Signal's Randall Sarafa  said . "People who have your number saved in their phone's contacts will still see your phone number since they already know it." Setting a new username requires account holders to provide two or more numbers at the end of it (e.g., axolotl.99) in an effort to keep them "egalitarian and minimize spoofing." Usernames can be changed any number of times, but it's worth noting that they are not logins or handles. Put differently, a username is an anonymous way to initiate conversations on the chat platform without having to share phone numbers. The feature is opt-in, although Signal said it's also taking steps to hide by default users' phone ...
The Future of Serverless Security in 2025: From Logs to Runtime Protection

The Future of Serverless Security in 2025: From Logs to Runtime Protection

Nov 28, 2024Cloud Security / Threat Detection
Serverless environments, leveraging services such as AWS Lambda, offer incredible benefits in terms of scalability, efficiency, and reduced operational overhead. However, securing these environments is extremely challenging. The core of current serverless security practices often revolves around two key components: log monitoring and static analysis of code or system configuration. But here is the issue with that: 1. Logs Only Tell Part of the Story Logs can track external-facing activities, but they don't provide visibility into the internal execution of functions. For example, if an attacker injects malicious code into a serverless function that doesn't interact with external resources (e.g., external APIs or databases), traditional log-based tools will not detect this intrusion. The attacker may execute unauthorized processes, manipulate files, or escalate privileges—all without triggering log events. 2. Static Misconfiguration Detection is Incomplete Static tools that check ...
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...

Private Internet Access – Get a Secure VPN to Protect Your Online Privacy

Aug 28, 2017
Since most of us rely upon the Internet for day-to-day activities today, hacking and spying have become a prime concern, and so have online security and privacy. The Internet has become a digital universe with websites collecting your sensitive information and selling them to advertisers, hackers looking for ways to steal your data from the ill-equipped networks, websites, and PCs, and government conducting mass surveillance—every model has shifted to data collection. So, what's the solution and how can you protect your privacy, defend against government surveillance and prevent malware attacks? Virtual Private Network —Yes, one of the most efficient solutions to maximize your privacy is to use a secure VPN service.

Satellite Phone Encryption Calls Can be Cracked in Fractions of a Second

Satellite Phone Encryption Calls Can be Cracked in Fractions of a Second

Jul 10, 2017
Security researchers have discovered a new method to decrypt satellite phone communications encrypted with the GMR-2 cipher in "real time" -- that too in mere fractions of a second in some cases. The new attack method has been discovered by two Chinese security researchers and is based on previous research by German academicians in 2012, showing that the phone's encryption can be cracked so quickly that attackers can listen in on calls in real time. The research, disclosed in a paper published last week by the security researchers in the International Association for Cryptologic Research, focused on the GMR-2 encryption algorithm that is commonly being used in most modern satellite phones, including British satellite telecom Inmarsat, to encrypt voice calls in order to prevent eavesdropping. Unlike previous 2012 research by German researchers who tried to recover the encryption key with the help of 'plaintext' attacks, the Chinese researchers attempted ...
Telegram Messenger Adds AI-powered Encrypted Voice Calls

Telegram Messenger Adds AI-powered Encrypted Voice Calls

Mar 31, 2017
Joining the line with rival chat apps WhatsApp, Viber, Facebook Messenger, and Signal, the Telegram instant messaging service has finally rolled out a much-awaited feature for the new beta versions of its Android app: Voice Calling . And what's interesting? Your calls will be secured by Emojis, and quality will be better using Artificial Intelligence. No doubt the company brought the audio calling feature quite late, but it's likely because of its focus on security — the voice calls on Telegram are by default based on the same end-to-end encryption methods as its Secret Chat mode to help users make secure calls. Unlike Signal or WhatsApp, Telegram does not support end-to-end encryption by default; instead, it offers a 'Secret Chat' mode, which users have to enable manually, to completely secure their chats from prying eyes. However, the voice calling feature in Telegram supports end-to-end encryption by default, enabling users to secure their chats in a way ...
OpenSSL Releases Patch For "High" Severity Vulnerability

OpenSSL Releases Patch For "High" Severity Vulnerability

Nov 10, 2016
As announced on Tuesday, the OpenSSL project team released OpenSSL version 1.1.0c that addresses three security vulnerabilities in its software. The most serious of all is a heap-based buffer overflow bug (CVE-2016-7054) related to Transport Layer Security (TLS) connections using *-CHACHA20-POLY1305 cipher suites. The vulnerability, reported by Robert Święcki of the Google Security Team on September 25, can lead to DoS attack by corrupting larger payloads, resulting in a crash of OpenSSL. The severity of the flaw is rated "High" and does not affect OpenSSL versions prior to 1.1.0. However, the OpenSSL team reports there is no evidence that the flaw is exploitable beyond a DoS attack. The OpenSSL project also patches a moderate severity flaw (CVE-2016-7053) that can cause applications to crash. "Applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 ...

Facebook Messenger adds End-to-End Encryption (Optional) for Secret Conversations

Facebook Messenger adds End-to-End Encryption (Optional) for Secret Conversations

Jul 08, 2016
Facebook has begun rolling out end-to-end encryption for its Messenger app, thus making its users' conversations completely private. The end-to-end encryption feature, dubbed " Secret Conversations ," will allow Messenger users to send and receive messages in a way that no one, including the FBI with a warrant, hackers and not even Facebook itself, can intercept them. But, this new feature will currently be available only to a small number of users for testing. So if you are one of those lucky users, you will be able to send end-to-end encrypted Secret Conversations through your Messenger app. Rest of the Messenger users will get Secret Conversations feature later this summer or in early fall, the company wrote in a Facebook newsroom post published today. Sounds exciting, right? But, there's a catch: Your conversations on Messenger will not be end-to-end encrypted by default, like what WhatsApp and Apple are offering. Instead, Facebook will require ...

WhatsApp turns on End-to-End Encryption by default for its 1 Billion Users

Apr 05, 2016
WhatsApp is updating its messaging app so that every text message and voice call will be encrypted for the company's one billion users. Yes, Whatsapp has finally implemented full end-to-end encryption , as promised a year ago. This means, from now every message, image or voice call you made will be secured by end-to-end encryption so that only you and the person you're communicating with can read the content of the message, and nobody in between, not even WhatsApp. In other words, this also means that WhatsApp would not be able to comply with any court order that demands access to the content of any conversation happens over its service. Starting today, you will see a notification on your WhatsApp conversation screen as your messenger becomes end-to-end encrypted, as shown in the screenshot. "Message you send to this chat and calls are now secured with end-to-end encryption. Tap for more info."  "This is because your messages are secured with a lock, ...
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 .

Paris Attacks — NO! We Can't Blame Edward Snowden and Encryption for Terror Attacks

Nov 17, 2015
Terrorist groups are increasingly using high-grade, advanced end-to-end encryption technologies so that no law enforcement can catch them. The deadliest terror attacks in Paris that killed 129 people were the latest example of it. How did the Terrorists Communicate and Organize the Plot? The Paris terrorists almost certainly used difficult-to-crack encryption technologies to organize the plot – locking law enforcement out, FBI Director James B. Comey told Congress Wednesday.

Let's Encrypt Project issues its First Free SSL/TLS Certificate

Let's Encrypt Project issues its First Free SSL/TLS Certificate

Sep 16, 2015
Last fall the non-profit foundation EFF ( Electronic Frontier Foundation ) launched an initiative called Let's Encrypt that aimed at providing Free Digital Cryptographic Certificates (TLS) to any website that needs them. Today, Let's Encrypt – a free automated Open-source Certificate Authority (CA) – has signed its first certificate, hitting what it calls a major milestone to encrypt all of the Web. Let's Encrypt enables any Internet site to protect its users with free SSL/TLS (Secure Socket Layer/Transport Layer Security) certificates that encrypt all the data passed between a website and users. Not just free, but the initiative also makes HTTPS implementation easier for any website or online shopping site owner in order to ensure the security of their customers' data. "Forget about hours (or sometimes days) of muddling through complicated programming to set up encryption on a website, or yearly fees," EFF explains . "Let's Encr...
Ultra-secure Blackphone Vulnerability lets Hackers Decrypt Texts

Ultra-secure Blackphone Vulnerability lets Hackers Decrypt Texts

Jan 28, 2015
The makers of ultra secure BlackPhone titled by Silent Circle as, " world's first Smartphone which places privacy and control directly in the hands of its users ," have recently fixed a critical vulnerability in the instant messaging application that allows hackers to run malicious code on the handsets. BlackPhone was also hacked last year at the BlackHat security conference , but the interesting factor about the recent hack was that the attackers only needed to send just a message on a targeted phone number in order to compromise the device. The vulnerability was first discovered and disclosed by Mark Dowd , a principal security researcher at the Australia-based consultancy firm Azimuth Security. Dowd discovered the issue late in 2014, but waited to disclose it until Blackphone got their patches and fixes in place. The flaw actually resides in Silent Text application — the secure text messaging application bundled with the BlackPhone handsets, which is al...
