Over Dozen Popular Email Clients Found Vulnerable to Signature Spoofing Attacks

Over Dozen Popular Email Clients Found Vulnerable to Signature Spoofing Attacks

April 30, 2019Swati Khandelwal
A team of security researchers has discovered several vulnerabilities in various implementations of OpenPGP and S/MIME email signature verification that could allow attackers to spoof signatures on over a dozen of popular email clients. The affected email clients include Thunderbird, Microsoft Outlook, Apple Mail with GPGTools, iOS Mail, GpgOL, KMail, Evolution, MailMate, Airmail, K-9 Mail, Roundcube and Mailpile. When you send a digitally signed email, it offers end-to-end authenticity and integrity of messages, ensuring recipients that the email has actually come from you. However, researchers tested 25 widely-used email clients for Windows, Linux, macOS, iOS, Android and Web and found that at least 14 of them were vulnerable to multiple types of practical attacks under five below-mentioned categories, making spoofed signatures indistinguishable from a valid one even by an attentive user. The research was conducted by a team of researchers from Ruhr University Bochum and
Facebook Collected Contacts from 1.5 Million Email Accounts Without Users' Permission

Facebook Collected Contacts from 1.5 Million Email Accounts Without Users' Permission

April 18, 2019Swati Khandelwal
Not a week goes without a new Facebook blunder. Remember the most recent revelation of Facebook being caught asking users new to the social network platform for their email account passwords to verify their identity? At the time, it was suspected that Facebook might be using access to users' email accounts to unauthorizedly and secretly gather a copy of their saved contacts. Now it turns out that the collection of email contacts was true, Facebook finally admits. In a statement released on Wednesday, Facebook said the social media company "unintentionally" uploaded email contacts from up to 1.5 million new users on its servers, without their consent or knowledge, since May 2016. In other words, nearly 1.5 million users had shared passwords for their email accounts with Facebook as part of its dubious verification process. A Facebook spokesperson shared information with Business Insider that the company was using harvested data to "build Facebook'

Hackers Compromise Microsoft Support Agent to Access Outlook Email Accounts

April 13, 2019Swati Khandelwal
If you have an account with Microsoft Outlook email service, there is a possibility that your account information has been compromised by an unknown hacker or group of hackers, Microsoft confirmed The Hacker News. Earlier this year, hackers managed to breach Microsoft's customer support portal and access information related to some email accounts registered with the company's Outlook service. Yesterday, a user on Reddit publicly posted a screenshot of an email which he received from Microsoft warning that unknown attackers were able to access some information of his OutLook account between 1 January 2019 and 28 March 2019. Another user on Reddit also confirmed that he/she too received the same email from Microsoft. According to the incident notification email, as shown below, attackers were able to compromise credentials for one of Microsoft's customer support agents and used it to unauthorisedly access some information related to the affected accounts, but not

Facebook Caught Asking Some Users Passwords for Their Email Accounts

April 03, 2019Swati Khandelwal
Facebook has been caught practicing the worst ever user-verification mechanism that could put the security of its users at risk. Generally, social media or any other online service asks users to confirm a secret code or a unique URL sent to the email address they provided for the account registration. However, Facebook has been found asking some newly-registered users to provide the social network with the passwords to their email accounts, which according to security experts is a terrible idea that could threaten privacy and security of its users. First noticed by Twitter account e-Sushi using the handle @originalesushi, Facebook has been prompting users to hand over their passwords for third-party email services, so that the company can "automatically" verify their email addresses. However, the prompt only appears for email accounts from certain email providers which Facebook considers to be suspicious. "Tested it myself registering 3 times with 3 differe

September 25, 2017Unknown
Another day, another data breach. This time one of the world's "big four" accountancy firms has fallen victim to a sophisticated cyber attack. Global tax and auditing firm Deloitte has confirmed the company had suffered a cyber attack that resulted in the theft of confidential information, including the private emails and documents of some of its clients. Deloitte is one of the largest private accounting firms in the U.S. which offers tax, auditing, operations consulting, cybersecurity advisory, and merger and acquisition assistance services to large banks, government agencies and large Fortune 500 multinationals, among others. The global accountancy firm said Monday that its system had been accessed via an email platform from October last year through this past March and that "very few" of its clients had been affected, the Guardian reports .

Yahoo Confirms 500 Million Accounts Were Hacked by 'State Sponsored' Hackers

September 23, 2016Mohit Kumar
500 million accounts — that's half a Billion users! That's how many Yahoo accounts were compromised in a massive data breach dating back to 2014 by what was believed to be a "state sponsored" hacking group. Over a month ago, a hacker was found to be selling login information related to 200 million Yahoo accounts on the Dark Web , although Yahoo acknowledged that the breach was much worse than initially expected. "A recent investigation by Yahoo! Inc. has confirmed that a copy of certain user account information was stolen from the company's network in late 2014 by what it believes is a state-sponsored actor," reads the statement . Yahoo is investigating the breach with law enforcement agency and currently believes that users' names, email addresses, dates of birth, phone numbers, passwords, and in some cases, encrypted and unencrypted security questions-answers were stolen from millions of Yahoo users. However, the company does not believe

Hacker is Selling 272 Million Email Passwords for Just $1

May 05, 2016Wang Wei
A massive database of 272 million emails and passwords for popular email services, including Gmail, Microsoft, and Yahoo, are being offered for sale on the Dark Web for less than $1, media reports. An anonymous Russian hacker, who goes by the moniker " the Collector ," was first spotted by cybersecurity firm Hold Security advertising 1.17 Billion user records for email accounts on a dark web forum. The stolen credentials apparently came from some of the world’s biggest email providers, including Gmail, Yahoo, Microsoft and Russia’s Mail.ru. When security analysts at Hold Security reached out to the hacker and began negotiating for the dataset to verify the authenticity of those records, the hacker only asked for 50 Rubles (less than a buck) in return of the complete dump. However, it seems that there is actually nothing to worry about. Hold Security CEO Alex Holden said that a large number of those 1.17 Billion accounts credentials turned out to be duplicate an
What is SMTP STS? How It improves Email Security for StartTLS?

What is SMTP STS? How It improves Email Security for StartTLS?

March 24, 2016Swati Khandelwal
Despite so many messaging apps, Email is still one of the widely used and popular ways to communicate in this digital age. But are your Emails secure? We are using email services for decades, but the underlying 1980s transport protocol used to send emails, Simple Mail Transfer Protocol (SMTP), is ancient and lacks the ability to secure your email communication entirely. However, to overcome this problem, SMTP STARTTLS was invented in 2002 as a way to upgrade an insecure connection to a secure connection using TLS. But, STARTTLS was susceptible to man-in-the-middle attacks and encryption downgrades. But worry not. A new security feature is on its way!!! SMTP STS: An Effort to Make Email More Secure Top email providers, namely Google, Microsoft, Yahoo!, Comcast, LinkedIn, and 1&1 Mail & Media Development, have joined forces to develop a new email standard that makes sure the emails you send are going through an encrypted channel and cannot be sniffed. Dubbed SMT

Deleting WhatsApp Messages Before 90 Days Could Land you in Jail

While the Indian people continue to struggle for Net Neutrality, a new problem surrounded them with the release of the latest policy for ‘ National Encryption Policy ’ by the Indian Government. If you delete your WhatsApp Messages or Emails that you receive or send before 90 days, it might be a crime and you can End-up In Jail. If the new National Encryption Policy implements that come up with weird suggestions — one should not delete WhatsApp conversation, Gmail or any email for 90 days, it would be an Internet Disaster. With the aim to ‘provide confidentiality of information’ and ensure ‘protection of sensitive or proprietary information’, the draft policy, proposed by an so-called ‘ expert panel ’ from the Department of Electronics and Information Technology ( DeitY ) , requires: Access to your Private Data The government wants to have access to all your encrypted information including your personal emails, text and voice messages, and data stored in a privat

'Undo Send' — How to Unsend Emails in Gmail

June 24, 2015Swati Khandelwal
Sending an important and confidential email to one of my friends and mistakenly clicked send to someone else. Holy crap! This is something experienced by everyone of us at some point. When we accidentally hit the reply-all button, send an email to the wrong person, or sometimes forget to attach a file, and then left only with an instant pain of regret. It feels like there is no going back. Isn't it? But to make you go back and rectify your mistakes, Google has rolled out a new feature that delays sending your email for 30 seconds after you hit Send, so that you can recall it if you want to make some changes. You Have 30 Seconds to Unsend an Email After the feature remained in public beta for six years, Google has finally brought this life-saving " Undo Send " feature to the main settings on the Web version of Google's Gmail service. Once enabled, the Undo Send feature offers you up to 30-second window to "undo" sending an outgoing ema
Tor-Based Dark Web Email Service Targeted by Government Spies

Tor-Based Dark Web Email Service Targeted by Government Spies

April 25, 2015Swati Khandelwal
The administrator of the popular Darknet email service , SIGAINT , is warning its users that the email service has become a target of a suspected law enforcement agency who tried to compromise it. About a week ago, SIGAINT has been targeted by an attacker who tried to hack the service by using nearly 70 bad Tor exit nodes , one of the service's administrator informed its users via the tor-talk mailing list on Thursday. Before jumping on the news, Let’s first understand what are Exit Nodes? As I said, SIGAINT uses TOR anonymization network which means when an email sent from one user to any destination, the email routed through multiple relays/nodes that actually aren't aware of the sender's identity. The last machine that processes the email known as a Tor exit relay or Tor exit node. The end user who receives that email can see the IP of the exit node instead of the IP address of the original sender. And this is how, SIGAINT allows you to send

Google Releases Chrome Extension for End-To-End Email Encryption

Google Releases Chrome Extension for End-To-End Email Encryption

December 18, 2014Mohit Kumar
Back in june this year, Google announced an alpha Google Chrome extension called " End-to-End " for sending and receiving emails securely, in wake of former NSA contractor Edward Snowden’s revelations about the global surveillance conducted by the government law-enforcements. Finally, the company has announced that it made the source code for its End-to-End Chrome extension open source via GitHub . Google is developing a user-friendly tool for individuals to implement the tough encryption standard known as Pretty Good Privacy (PGP) in an attempt to fully encrypt people’s Gmail messages that can’t even be read by Google itself, nor anyone else other than the users exchanging the emails. PGP is an open source end-to-end encryption standard for almost 20 years, used to encrypt e-mail over the Internet providing cryptographic privacy and authentication for data communication, which makes it very difficult to break. But implementing PGP is too complicated for m

Google Admits that It Reads your Emails

April 16, 2014Swati Khandelwal
Google has updated its privacy terms and conditions on Monday to offer more transparency regarding its email-scanning practices. One of the world’s biggest Web internet giant, Google, made it clear that the information its users submit and share with its systems is all analyzed. Last year, Google was accused of its illegal interception of all electronic communications sent to Gmail account holders and using the gathering data to sell and place advertisements in order to serve related ads to its users. Practically, the more information you let Google collect about you, the more accurate its adverts become. But Google has long insisted that its scanning practices are outlined in its terms of service. So, finally admitting the accusation, Google has made some changes in its terms of service res a new paragraph that explains the manner in which its software automatically scans and analyzes the content of Gmail messages when they are sent, received, and stored.

Yahoo Mail turns on HTTPS encryption by default to protect users

Yahoo Mail turns on HTTPS encryption by default to protect users

January 09, 2014Wang Wei
After the release of NSA Secret spying over Internet communications, I am expecting from all tech companies to make surveillance significantly harder. Yahoo has HTTPS encryption support since late 2012, but users had to opt in to use the feature. Documents revealed by the Edward Snowden shows that the NSA secretly accessed data from several tech giants, including Yahoo, by intercepting unencrypted Internet traffic in a program called Muscular. As promised back in October 2013,  Yahoo  has finally enabled the HTTPS connections by default for their users, that will now automatically encrypts the connections between users and its email service. Jeff Bonforte , senior vice-president of communication products at Yahoo announced  in a blog post: It is 100% encrypted by default and protected with 2,048 bit certificates. This encryption extends to your emails, attachments, contacts, as well as Calendar and Messenger in Mail. HTTPS by default is really a good news for Yahoo users, that will
