hacking-team-pwn2own
The Tencent Keen Security Lab Team from China has won a total prize money of $215,000 in the 2016 Mobile Pwn2Own contest run by Trend Micro’s Zero Day Initiative (ZDI) in Tokyo, Japan. Despite the implementation of high-security measures in current devices, the famous Chinese hackers crew has successfully hacked both Apple’s iPhone 6S as well as Google’s Nexus 6P phones. For hacking Apple’s iPhone 6S, Keen Lab exploited two iOS vulnerabilities – a use-after-free bug in the renderer and a memory corruption flaw in the sandbox – and stole pictures from the device, for which the team was awarded $52,500.The iPhone 6S exploit successfully worked despite the iOS 10 update rolled out by Apple this week.

openssl-ddos-attackThe OpenSSL Foundation has patched over a dozen vulnerabilities in its cryptographic code library, including a high severity bug that can be exploited for denial-of-service (DoS) attacks. OpenSSL is a widely used open-source cryptographic library that provides encrypted Internet connections using Secure Sockets Layer (SSL) or Transport Layer Security (TLS) for the majority of websites, as well as other secure services. The vulnerabilities exist in OpenSSL versions 1.0.1, 1.0.2 and 1.1.0 and patched in OpenSSL versions 1.1.0a, 1.0.2i and 1.0.1u. The Critical-rated bug (CVE-2016-6304) can be exploited by sending a large OCSP Status Request extension on the targeted server during connection negotiations, which causes memory exhaustion to launch DoS attacks, the OpenSSL Project said.

nsa-hacking-tool-exploitsIf you are a hacker, you might have enjoyed the NSA’s private zero-day exploits, malware and hacking tools that were leaked last month. But the question is: How these hacking tools ended up into the hands of hackers? It has been found that the NSA itself was not directly hacked, but a former NSA employee carelessly left those hacking tools on a remote server three years ago after an operation and a group of Russian hackers found them, sources close to the investigation told Reuters. The leaked hacking tools, which enable hackers to exploit vulnerabilities in systems from big vendors like Cisco Systems, Juniper, and Fortinet, were dumped publicly online by the group calling itself “The Shadow Brokers.”

hack-mysql-databaseTwo critical zero-day vulnerabilities have been discovered in the world’s 2nd most popular database management software MySQL that could allow an attacker to take full control over the database. Polish security researcher Dawid Golunski has discovered two zero-days, CVE-2016-6662 and CVE-2016-6663, that affect all currently supported MySQL versions as well as its forked such as MariaDB and PerconaDB. Golunski further went on to publish details and a proof-of-concept exploit code for CVE-2016-6662 after informing Oracle of both issues, along with vendors of MariaDB and PerconaDB.Both MariaDB and PerconaDB had fixed the vulnerabilities, but Oracle had not. The vulnerability (CVE-2016-6662) can be exploited by hackers to inject malicious settings into MySQL configuration files or create their own malicious ones.

e-Voting

Threats to our electoral process can come from outside the country or nefarious insiders. Our country needs to be better prepared. After Russian state security personnel were accused of hacking the Democratic National Committee, the possibility of outsiders manipulating the American political process became a reality. With the reliance on computers to collect votes, report results, communicate campaign strategies, and coordinate voter registration activities, the electoral process has new vulnerabilities. In addition, rogue countries aren’t the only threats; insiders are also capable of manipulating election results. Here are six ways that elections can be hacked.

NSA-Exploits-Cisco-extrabacon-modifiedRecently released NSA exploit from “The Shadow Brokers” leak that affects older versions of Cisco System firewalls can work against newer models as well. Dubbed ExtraBacon, the exploit was restricted to versions 8.4.(4) and earlier versions of Cisco’s Adaptive Security Appliance (ASA) – a line of firewalls designed to protect corporate, government networks and data centers. However, the exploit has now been expanded to 9.2.(4) after researchers from Hungary-based security consultancy SilentSignal  were able to modify the code of ExtraBacon to make it work on a much newer version of Cisco’s ASA software. Both Cisco and Fortinet have confirmed their firewalls are affected by exploits listed in the Shadow Brokers cache that contained a set of “cyber weapons” stolen from the Equation Group.

Cyber security concep with lock.Android has Fallen! Yet another set of Android security vulnerabilities has been discovered in Qualcomm chipsets that affect more than 900 Million Android smartphones and tablets worldwide. What’s even worse: Most of those affected Android devices will probably never be patched. Dubbed “Quadrooter,” the set of four vulnerabilities discovered in devices running Android Marshmallow and earlier that ship with Qualcomm chip could allow an attacker to gain root-level access to any Qualcomm device. The chip, according to the latest statistics, is found in more than 900 Million Android tablets and smartphones. That’s a very big number. The vulnerabilities have been disclosed by a team of Check Point researchers at the DEF CON 24 security conference in Las Vegas.

Lastpass

Password managers seem like a great idea, given rampant password reuse, poor abilities to create strong passwords by the average user and the sheer number of credentials we’re supposed to remember. But major vulnerabilities have been found in LastPass—opening the door to a full remote compromise for its users.

Independent security researcher Tavis Ormandy said that the zero-day flaw can be exploited using a drive-by technique with a malicious website. If successful, the attacker gains the digital keys to the kingdom—all of the credentials that the user has stored for online services.

“Are people really using this lastpass [sic] thing?” Ormandy tweeted. “I took a quick look and can see a bunch of obvious critical problems.”

One Ormandy Twitter follower responded, “I’m perplexed anyone uses an online service to store passwords”—to which Ormandy responded, “Yeah, me too.”

Linux-KernelHow to Hack an Android device? It is possibly one of the most frequently asked questions on the Internet. Although it’s not pretty simple to hack Android devices and gadgets, sometimes you just get lucky to find a backdoor access. Thanks to Allwinner, a Chinese ARM system-on-a-chip maker, which has recently been caught shipping a version of Linux Kernel with an incredibly simple and easy-to-use built-in backdoor. Chinese fabless semiconductor company Allwinner is a leading supplier of application processors that are used in many low-cost Android tablets, ARM-based PCs, set-top boxes, and other electronic devices worldwide.

OpenSSL-Vulnerability
OpenSSL has released a series of patches against six vulnerabilities, including a pair of high-severity flaws that could allow attackers to execute malicious code on a web server as well as decrypt HTTPS traffic. OpenSSL is an open-source cryptographic library that is the most widely being used by a significant portion of the Internet services; to cryptographically protect their sensitive Web and e-mail traffic using the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocol. One of the high-severity flaws, CVE-2016-2107, allows a man-in-the-middle attacker to initiate a “Padding Oracle Attack” that can decrypt HTTPS traffic if the connection uses AES-CBC cipher and the server supports AES-NI. A Padding Oracle flaw weakens the encryption protection by allowing attackers to repeatedly request plaintext data about an encrypted payload content. The Padding Oracle flaw (exploit code) was discovered by Juraj Somorovsky using his own developed tool called TLS-Attacker, which allows developers to test their TLS servers with specific TLS messages.
