Security researchers have publicly disclosed an unpatched zero-day vulnerability in the firmware of AT&T DirecTV WVB kit after trying to get the device manufacturer to patch this easy-to-exploit flaw over the past few months. The problem is with a core component of the Genie DVR system that's shipped free of cost with DirecTV and can be easily exploited by hackers to gain root access and take full control of the device, placing millions of people who've signed up to DirecTV service at risk. The vulnerability actually resides in WVBR0-25 —a Linux-powered wireless video bridge manufactured by Linksys that AT&T provides to its new customers. DirecTV Wireless Video Bridge WVBR0-25 allows the main Genie DVR to communicate over the air with customers' Genie client boxes (up to 8) that are plugged into their TVs around the home. Trend Micro researcher Ricky Lawshae, who is also a DirecTV customer, decided to take a closer look at the device and found that Linksy...

The U.S. federal officials have arrested three hackers who have pleaded guilty to computer-crimes charges for creating and distributing Mirai botnet that crippled some of the world's biggest and most popular websites by launching the massive DDoS attacks last year. According to the federal court documents unsealed Tuesday, Paras Jha (21-year-old from New Jersey), Josiah White (20-year-old Washington) and Dalton Norman (21-year-old from Louisiana) were indicted by an Alaska court last week on multiple charges for their role in massive cyber attacks conducted using Mirai botnet. Mirai is a piece of nasty IoT malware that scans for insecure routers, cameras, DVRs, and other Internet of Things devices which are still using their default passwords and then add them into a botnet network, which is then used to launch DDoS attacks on websites and Internet infrastructure. According to his plea agreement, Jha " conspired to conduct DDoS attacks against websites and web ho...

Even after so many efforts by Google like launching bug bounty program and preventing apps from using Android accessibility services , malicious applications somehow manage to get into Play Store and infect people with malicious software. The same happened once again when security researchers discovered at least 85 applications in Google Play Store that were designed to steal credentials from users of Russian-based social network VK.com and were successfully downloaded millions of times. The most popular of all masqueraded as a gaming app with more than a million downloads. When this app was initially submitted in March 2017, it was just a gaming app without any malicious code, according to a blog post published Tuesday by Kaspersky Lab. However, after waiting for more than seven months, the malicious actors behind the app updated it with information-stealing capabilities in October 2017. Besides this gaming app, the Kaspersky researchers found 84 such apps on Google Play ...

A 19-year-old vulnerability has been re-discovered in the RSA implementation from at least 8 different vendors—including F5, Citrix, and Cisco—that can give man-in-the-middle attackers access to encrypted messages. Dubbed ROBOT ( Return of Bleichenbacher's Oracle Attack ), the attack allows an attacker to perform RSA decryption and cryptographic operations using the private key configured on the vulnerable TLS servers. ROBOT attack is nothing but a couple of minor variations to the old Bleichenbacher attack on the RSA encryption protocol. First discovered in 1998 and named after Swiss cryptographer Daniel Bleichenbacher, the Bleichenbacher attack is a padding oracle attack on RSA-based PKCS#1 v1.5 encryption scheme used in SSLv2. Leveraging an adaptive chosen-ciphertext attack which occurred due to error messages by SSL servers for errors in the PKCS #1 1.5 padding, Bleichenbacher attack allows attackers to determine whether a decrypted message is correctly padded. ...

Hackers always first go for the weakest link to quickly gain access to your online accounts. Online users habit of reusing the same password across multiple services gives hackers opportunity to use the credentials gathered from a data breach to break into their other online accounts. Researchers from security firm 4iQ have now discovered a new collective database on the dark web (released on Torrent as well) that contains a whopping 1.4 billion usernames and passwords in clear text. The aggregate database, found on 5 December in an underground community forum, has been said to be the largest ever aggregation of various leaks found in the dark web to date, 4iQ founder and chief technology officer Julio Casal noted in a blog post. Though links to download the collection were already circulating online over dark-web sites from last few weeks, it took more exposure when someone posted it on Reddit a few days ago, from where we also downloaded a copy and can now verify its auth...
