Over Dozen Popular Email Clients Found Vulnerable to Signature Spoofing Attacks

Over Dozen Popular Email Clients Found Vulnerable to Signature Spoofing Attacks

Apr 30, 2019
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 ...
Rapidly Growing Electrum Botnet Infects Over 152,000 Users; Steals $4.6 Million

Rapidly Growing Electrum Botnet Infects Over 152,000 Users; Steals $4.6 Million

Apr 30, 2019
An ongoing attack against Electrum Bitcoin wallets has just grown bigger and stronger with attackers now targeting the whole infrastructure of the exchange with a botnet of over 152,000 infected users, raising the amount of stolen users' funds to USD 4.6 million. Electrum has been facing cyber attacks since December last year when a team of cybercriminals exploited a weakness in the Electrum infrastructure to trick wallet users into downloading the malicious versions of the software. In brief, the attackers added some malicious servers to the Electrum peer network which were designed to purposely display an error to legitimate Electrum wallet apps, urging them to download a malicious wallet software update from an unofficial GitHub repository. The phishing attack eventually allowed attackers to steal wallet funds (almost 250 Bitcoins that equals to about $937,000 at the time) and take full control over the infected systems. To counter this, the developers behind Electrum...
Unprotected Database Exposes Personal Info of 80 Million American Households

Unprotected Database Exposes Personal Info of 80 Million American Households

Apr 30, 2019
A team of security researchers has claims to have found a publicly-accessible database that exposes information on more than 80 million U.S. households—nearly 65 percent of the total number of American households. Discovered by VPNMentor's research team lead by hacktivists Noam Rotem and Ran Locar, the unsecured database includes 24GB of extremely detailed information about individual homes, including their full names, addresses, ages, and birth dates. The massive database which is hosted on a Microsoft cloud server also contains coded information noted in "numerical values," which the researchers believe correlates to homeowners' gender, marital status, income bracket, status, and dwelling type. Fortunately, the unprotected database does not contain passwords, social security numbers or payment card information related to any of the affected American households. The researchers verified the accuracy of some data in the cache, but they did not download the ...

Docker Hub Suffers a Data Breach, Asks Users to Reset Password

Docker Hub Suffers a Data Breach, Asks Users to Reset Password

Apr 27, 2019
Docker Hub, one of the largest cloud-based library of Docker container images, has suffered a data breach after an unknown attacker gained access to the company's single Hub database. Docker Hub is an online repository service where users and partners can create, test, store and distribute Docker container images, both publicly and privately. The breach reportedly exposed sensitive information for nearly 190,000 Hub users (that's less than 5 percent of total users), including usernames and hashed passwords for a small percentage of the affected users, as well as Github and Bitbucket tokens for Docker repositories. Docker Hub started notifying affected users via emails informing them about the security incident and asking them to change their passwords for Docker Hub, as well as any online account using the same password. "On Thursday, April 25th, 2019, we discovered unauthorized access to a single Hub database storing a subset of non-financial user data. Upon ...

New York, Canada, Ireland Launch New Investigations Into Facebook Privacy Breaches

Apr 27, 2019
Facebook has a lot of problems, then there are a lot of problems for Facebook—and both are not going to end anytime sooner. Though Facebook has already set aside $5 billion from its revenue to cover a possible fine the company is expecting as a result of an FTC investigation over privacy violations, it seems to be just first installment of what Facebook has to pay for continuously ignoring users' privacy. This week, Facebook has been hit with three new separate investigations from various governmental authorities—both in the United States and abroad—over the company's mishandling of its users' data . New York Attorney General to Investigate Facebook Email Collection Scandal New York Attorney General is opening an investigation into Facebook's unauthorized collection of the email contacts of more than 1.5 million users during site registration without their permission. Earlier this month, Facebook was caught practicing the worst ever user-verification mechanism...
