Zoom Bug Allowed Snoopers Crack Private Meeting Passwords in Minutes

Zoom Bug Allowed Snoopers Crack Private Meeting Passwords in Minutes
July 30, 2020Ravie Lakshmanan
Popular video conferencing app Zoom recently fixed a new security flaw that could have allowed potential attackers to crack the numeric passcode used to secure private meetings on the platform and snoop on participants. Zoom meetings are by default protected by a six-digit numeric password, but according to Tom Anthony, VP Product at SearchPilot who identified the issue , the lack of rate limiting enabled "an attacker to attempt all 1 million passwords in a matter of minutes and gain access to other people's private (password protected) Zoom meetings." It's worth noting that Zoom began requiring a passcode for all meetings back in April as a preventive measure to combat Zoom-bombing attacks, which refers to the act of disrupting and hijacking Zoom meetings uninvited to share obscene and racist content. Anthony reported the security issue to the company on April 1, 2020, along with a Python-based proof-of-concept script, a week after which Zoom patched the flaw

October 07, 2017Swati Khandelwal
Another day, Another data breach disclosure. This time the popular commenting system has fallen victim to a massive security breach. Disqus, the company which provides a web-based comment plugin for websites and blogs, has admitted that it was breached 5 years ago in July 2012 and hackers stole details of more than 17.5 million users. The stolen data includes email addresses, usernames, sign-up dates, and last login dates in plain text for all 17.5 million users. What's more? Hackers also got their hands on passwords for about one-third of the affected users, which were salted and hashed using the weak SHA-1 algorithm. The company said the exposed user information dates back to 2007 with the most recently exposed from July 2012. According to Disqus, the company became aware of the breach Thursday (5th October) evening after an independent security researcher Troy Hunt, who obtained a copy of the site's information, notified the company. Within about 24 hours,

December 16, 2016Mohit Kumar
Recently Yahoo disclosed a three-year-old massive data breach in its company that exposed personal details associated with more than 1 Billion user accounts , which is said to be the largest data breach of any company ever. The new development in Yahoo!'s 2013 data breach is that the hacker sold its over Billion-user database on the Dark Web last August for $300,000, according to Andrew Komarov, Chief Intelligence Officer (CIO) at security firm InfoArmor. Komarov told the New York Times that three different buyers, including two "prominent spammers" and the third, is believed to be involved in espionage tactics paid $300,000 to gain control of the entire database. The hacker group that breached Yahoo and sold the database is believed to based in Eastern Europe, but the company still does not know if this information is accurate or not. Beside full names, passwords, date of births and phone numbers of 1 Million Yahoo users, the database also includes backup em

DailyMotion Hacked — 85 Million User Accounts Stolen
December 05, 2016Swati Khandelwal
Another day, another data breach. This time a popular video sharing platform DailyMotion has allegedly been hacked and tens of millions of users information have been stolen. Breach notification service LeakedSource announced the data breach on Monday after the company obtained 85.2 Million records from Dailymotion. According to LeakedSource, the DailyMotion data breach appears to have taken place on October 20, 2016, which means it is possible that hackers have been circulating the data for over a month. The stolen data consists of 85.2 Million unique email addresses and usernames and around 20 percent of the accounts (more than 18 Million users) had hashed passwords tied to them. The passwords were protected using the Bcrypt hashing algorithm with ten rounds of rekeying, making it difficult for hackers to obtain user's actual password. Bcrypt is a cryptographic algorithm that makes the hashing process so slow that it would literally take centuries to actual brute-

Warning! 32 Million Twitter Passwords May Have Been Hacked and Leaked

Warning! 32 Million Twitter Passwords May Have Been Hacked and Leaked
June 09, 2016Swati Khandelwal
The world came to know about massive data breaches in some of the most popular social media websites including LinkedIn , MySpace , Tumblr , Fling, and VK.com when an unknown Russian hacker published the data dumps for sale on the underground black marketplace. However, these are only data breaches that have been publicly disclosed by the hacker. I wonder how much more stolen data sets this Russian, or other hackers are holding that have yet to be released. The answer is still unknown, but the same hacker is now claiming another major data breach, this time, in Twitter. Login credentials of more than 32 Million Twitter users are now being sold on the dark web marketplace for 10 Bitcoins (over $5,800). LeakedSource, a search engine site that indexes leaked login credentials from data breaches, noted in a blog post that it received a copy of the Twitter database from Tessa88, the same alias used by the hacker who provided it hacked data from Russian social network VK.com

VK.com HACKED! 100 Million Clear Text Passwords Leaked Online
June 06, 2016Swati Khandelwal
Another day, another Data Breach! Now, Russia's biggest social networking site VK.com is the latest in the line of historical data breaches targeting social networking websites. The same hacker who previously sold data dumps from MySpace , Tumblr , LinkedIn , and Fling.com, is now selling more than 100 Million VK.com records for just 1 Bitcoin ( approx. US$580 ). The database contains information like full names ( first names and last names ), email addresses, plain-text passwords, location information, phone numbers and, in some cases, secondary email addresses. Yes, plain-text passwords. According to Peace, the passwords were already in plain text when the VK.com was hacked. So, if the site still stores passwords in cleartext today, this could be a real security risk for its users. The data breach has initially been reported by LeakedSource search engine, which received portions of the database from one of the people who bought it. The company has already analyzed t

New Citadel Trojan Targets Your Password Managers

New Citadel Trojan Targets Your Password Managers
November 21, 2014Mohit Kumar
Unless we are a human supercomputer, remembering password is not an easy task and that too, if you have a different password for every different site. But luckily to make the whole process easy, there is a growing market for password managers which provides an extra layer of protection. Wait! Wait! Seriously?? Security researchers have discovered a new variant of data-stealing Citadel Trojan program used by cybercriminals to slurp up users' master passwords for a number of password management applications and other authentication programs, which will let you think twice before using one. Citadel Trojan malware program has typically been used to steal online banking credentials and other financial information by masquerading itself as legitimate banking sites when victims open it in their local browser, which is also known as a man-in-the-browser attack . The malware has previously targeted users' credentials stored in the password management applications included

Keeping the Bots at Bay: How to Detect Brute Force Attacks

Keeping the Bots at Bay: How to Detect Brute Force Attacks
November 20, 2014Swati Khandelwal
Thanks to recent events involving certain celebrities' stolen pictures, "brute-force attack" is now one of the hot buzz words making its rounds. As an IT professional - do you know what a brute force attack is, how to spot one when it happens, and how to prevent it? A brute-force attack is, simply, an attack on a username, password, etc. that systematically checks all possible combinations until the correct one is found. Scripts are usually used in these attacks to automate the process of arriving at the correct username/password combination. This is why time is of the essence when it comes to detecting and stopping a brute force attack – the more time the attacker has, the more passwords can be tried. Brute force attacks are one of the few hacks detectable by their volume, rather than their type. In your web (or proprietary app) logs, you'll usually see a crazy amount of failed login attempts, usually originating from the same IP address. You might even see the same accoun

Hacking Traffic Lights is Amazingly Really Easy

Hacking Traffic Lights is Amazingly Really Easy
August 21, 2014Swati Khandelwal
Hacking Internet of Things (IoTs) have become an amazing practice for cyber criminals out there, but messing with Traffic lights would be something more crazy for them. The hacking scenes in hollywood movies has just been a source of entertainment for the technology industry, like we've seen traffic lights hacked in Die Hard and The Italian Job , but these movies always inspire hackers to perform similar hacking attacks in day-to-day life. Security researchers at the University of Michigan have not only hacked traffic light signals in real life, but also claimed that it's actually shockingly easy to perform by anyone with a laptop and the right kind of radio. If we compare the traffic light hacks in movies and real life, the reality is much easier. In a paper study published this month, the security researchers describe how a series of major security vulnerabilities in traffic light systems allowed them to very easily and very quickly seized control of the whole system of at

How to Weaponize your Cat to Hack Neighbours' Wi-Fi Passwords

How to Weaponize your Cat to Hack Neighbours’ Wi-Fi Passwords
August 10, 2014Swati Khandelwal
What do you expect from your cat to come back with?? Perhaps with a mouse or a bird – none of your use. But what if she come back with your neighbours' wifi details? Really Interesting! A creative security researcher has found a way to use his pet cat mapping dozens of vulnerable Wi-Fi networks in his neighborhood. Gene Bransfield , a security researcher with Tenacity, managed to turn his wife's grandmother's pet cat Coco into a roaming detector for free Wifi networks by just using a custom-built collar , which was made from a Wi-Fi card, GPS module, Spark Core chip, battery and some fetching leopard print fabric. Bransfield dubbed his experiment " Warkitteh " – on the concept of " Wardriving ", where hackers used unsecured Wi-Fi connections from a parked car. He decided to turn his cat into a hacker because he found the idea amusing, and also because cats are the one that consumes as much as 15 per cent of internet traffic, with the popularity among the internet users.

Oops... Popular Password Managers Are Not As Secure As You Think
July 14, 2014Swati Khandelwal
Just few days ago, we reported about two critical vulnerability in mobile version of the most popular password manager application from a popular Password management company RoboForm , which manages your passwords for different websites. Now, researchers have published a detailed explanation on the security vulnerabilities discovered in five different and popular password managers , including RoboForm, that could allow cybercriminals to grab your credentials. The serious security holes were found and reported by the University of California Berkeley researchers named: Zhiwei Li, Warren He, Devdatta Akhawe and Dawn Song . The critical vulnerabilities were discovered in the popular password managers that includes RoboForm, LastPass, My1Login, PasswordBox and NeedMyPassword . " Our attacks are severe: in four out of the five password managers we studied, an attacker can learn a user's credentials for arbitrary websites, " Researchers wrote in the paper (PDF) tit

Securing Passwords with Bcrypt Hashing Function

Securing Passwords with Bcrypt Hashing Function
April 10, 2014Anonymous
Passwords are the first line of defense against cyber criminals. It is the most vital secret of every activity we do over the internet and also a final check to get into any of your user account, whether it is your bank account, email account, shopping cart account or any other account you have. We all know storing passwords in clear text in your database is ridiculous. Many desktop applications and almost every web service including, blogs, forums eventually need to store a collection of user data and the passwords, that has to be stored using a hashing algorithm. Cryptographic hash algorithms MD5, SHA1, SHA256, SHA512, SHA-3 are general purpose hash functions, designed to calculate a digest of huge amounts of data in as short a time as possible. Hashing is the greatest way for protecting passwords and considered to be pretty safe for ensuring the integrity of data or password. The benefit of hashing is that if someone steals the database with hashed passwords, they o

Tesla Cars Can Be Hacked to Locate and Unlock Remotely
March 31, 2014Swati Khandelwal
Smart Phones, Smart TVs, Smart Refrigerators, even Smart Cars! When it comes to Smart devices, we simply provide them the master control of various tasks to make our life easy and more comfortable, unaware about its worst impact. At the starting of last month we reported that by using a $20 toolkit called CAN Hacking Tool (CHT) , hackers can hack your Smart Cars, giving entire control of your car to an attacker from windows and headlights to its steering and brakes. Now a new research carried out on the  Tesla Smart car  has proved that the hackers are able to remotely locate or unlock the Tesla Motors Inc. electric vehicles, just by cracking a six-character password using traditional hacking techniques. At the Black Hat Asia security conference in Singapore on Friday, Nitesh Dhanjani , a corporate security consultant and Tesla owner, said a recent study conducted by him on the Tesla Model S sedan pointed out several design flaws in its security system, and there wasn&

Crowd-Funding site Kickstarter Hacked! It's time to change your Password
February 16, 2014Wang Wei
If you have an account at the popular crowd funding site Kickstarter , it's time to change your account's password. Kickstarter's CEO Yancey Strickle r says that the company has been hacked by an unknown hacker earlier this week. Kickstarter said in a blog post that no credit card information was stolen in Data Breach , but users' personal information has been compromised and they also haven't found evidence of unauthorized activities on accounts. Data accessed and stolen by hackers included usernames, email addresses, mailing addresses, phone numbers and encrypted passwords of the users. Facebook usernames and logins were not compromised for those who use that log-in system to get on Kickstarter. According to a Kickstarter's team member, the older users' passwords were encrypted using salted SHA1  and newer users' passwords are encrypted with a stronger hashing algorithm called ' bcrypt '. Hackers could attempt to crack the encrypted pa

Cryptography Hacks - Hash Encryption using DuckDuckGo Search Engine
January 30, 2014Mohit Kumar
Over the past several months, it has become clear that the Internet and our Privacy have been fundamentally compromised. A Private search engine DuckDuckGo claims that when you click on one of their search results, they do not send personally identifiable information along with your request to the third party. Like Google dorks (advance search patterns), there are thousands of similar, but technically more useful search hacks are also available in DuckDuckGo called DuckDuckGoodies . Today I am going to share about Handy " Cryptography " using DuckDuckGo search engine . Whether you are a Hacker, Cracker or a Researcher, you need to face a number of hash strings in your day to day life. Hashing is a one way encryption of a plain text or a file, generally used to secure passwords or to check the integrity of the file. There is a certain set of hashing algorithms, e.g.md5, sha1, sha-512 etc. A hash function generates the exact output if executed n numbe

Hackers behind TARGET data breach looking for Pro-cracker to decrypt Credit card PINs

Hackers behind TARGET data breach looking for Pro-cracker to decrypt Credit card PINs
January 10, 2014Swati Khandelwal
I think you haven't forgotten the massive data breach occurred at TARGET , the third-largest U.S. Retailer during last Christmas Holidays. People shop during Black Friday sales in which over 40 million Credit & Debit cards were stolen, used to pay for purchases at its 1500 stores nationwide in the U.S. TARGET officially confirmed that the encrypted PINs (personal identification numbers) of payment cards were stolen in the breach, since the stolen pin data were in encrypted form so they were confident that the information was " Safe and Secure ", because PIN cannot be decrypted without the right key. The Breach was caused by a malware attack, that allowed the criminals to manipulate Point of Sale (PoS) systems without raising red flags and the card numbers compromised in the breach are now flooding underground forums for sale. Possibly a group of Eastern European cyber criminals who specializes in attacks on merchants and Point-of-Sale terminals either attached a physical device
