Google Play Store Fails Vetting Again…

In case you haven’t noticed, I like beating up on the Google Play Store just a bit. More fake apps were released onto the Play Store. Instead of stealing personal information through phony banking apps, attackers are now spamming users with ads through fake WhatsApp messenger lookalikes.

Oracle Identity Manager Hacked through a Critical Flaw

 

Based in Redwood, California, Oracle Corporation is the largest software company whose primary business is database products. Historically, Oracle has targeted high-end workstations and minicomputers as the server platforms to run its database systems. Its relational database was the first to support the SQL language, which has since become the industry standard.

A exploit was found in Oracle’s identity management system. This exploix has been marked as CVE-2017-10151, it has been assigned the highest CVSS score of 10 and is easy to exploit without any user interaction.

This CVE is due to a security loophole involving a default account that allows an unathenticated attacker on the same network to compromise the Oracle Identity Manager through HTTP.

The full details of this vulnerability have not yet been released by Oracle.

“This vulnerability is remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials,” Oracle’s advisory reads.

The easily exploitable vulnerability affects Oracle Identity Manager versions 11.1.1.7, 11.1.1.9, 11.1.2.1.0, 11.1.2.2.0, 11.1.2.3.0 and 12.2.1.3.0.

Oracle has already released patches for all versions of the products that were affected by this CVE. all users should update to the latest version of Oracle to patch the vulnerability before a hacker has the chance to exploit it.

Encryption system used to exploit protected Wifi networks

Everyone knows that they could be a potential target for cyber-crime; as it often appears in the news almost every day. But just how vulnerable is an individual? CERT recently made a statement about how your Wifi network could be exploited if proper precautions are not taken.

On October 16th, 2017, the Computer Emergency Readiness Team made an announcement that addresses the protection of your sensitive information. In short, its advice is to update all your devices when security advancements are available. The reason for this is that a widely used encryption system used on wireless networks can lead to a breach of your credit card information, emails, passwords, etc.

Essentially, the system allows a hacker to gain access to the internet traffic that occurs between computers. Once in, the hacker can manipulate the data that is recovered. Depending on the target’s network configurations, it is even possible for the attacker to inject malware into the network. The unsettling part about this encryption system is that it has the capability of effecting a very wide range of devices including Android, Apple, Linux, and Windows.

Companies such as Intel, Microsoft, Google, and Apple have heeded this advice and have released updates that will help protect people with their devices from this issue.

Hackers Exploit Microsoft Servers to Mine Cryptocurrency

Mining for cryptocurrency is becoming an extremely profitable investment. One of the most popular currencies, bitcoin, is skyrocketing in value. One bitcoin is currently worth $4297 U.S. dollar. These currencies are becoming more and more popular to use online for illegal activity because it’s more difficult to trace, and increasing in value so quickly.

Now to this recent attack on servers running Windows server 2003. An exploit in this software was discovered in March of this year (2017), the exploit targets the web server in Windows server 2003. Hackers have now taken to attacking servers that have not patched to the most recent update that fixes the exploit. The exploit infects the server and adds it to a botnet for the hacker to control and mine for cryptocurrency. In this attack the hackers were mining for a currency called Monero, this currency is completely untraceable and anonymous. Hackers prefer mining for Monero because it uses an algorithm called CryptoNight which works on CPUs and GPUs and unlike Bitcoin requires no special hardware to begin mining. This currency is currently significantly less valuable than bitcoin, at the time of writing 1 Monero is worth $90 U.S. dollars but, like all cryptocurrency the value fluctuates quite frequently. This attack gained the hackers $63,000 worth of Monero in 3 months. There are quite a few pieces of malware that exploit servers to mine this currency. One piece of malware called Adylkuzz uses the EternalBlue exploit, which was actually created by the NSA and released by a group called the Shadow Brokers this exploit was used in the WannaCry ransomware attack. BondNet is another form of malware that also creates a botnet to mine Monero.

BlueBorne, a Bluetooth Vulnerability

Armis has identified a new threat to almost every device we own. There are eight vulnerabilities that have been identified, four of which are critical. These vulnerabilities affect over 5 billion Android, Windows, iOS, and Linux devices. This vulnerability is known as BlueBorne.

What makes this vulnerability different than most cyber attacks is that there is no link that a user has to click on or a malicious file that the user has to download to become a victim. The user doesn’t even have to be connected to the internet. Instead, BlueBorne is spread through a devices Bluetooth connection. The attack doesn’t require the targeted device to be paired to the attackers device or even for the targeted device to be set to discoverable mode.

This all contributes to BlueBorne being easily spread to devices at a possible unprecedented rate. Bluetooth processes have high privileges on all operating systems which allows this exploit to completely take over the device. Android devices are vulnerable to remote code execution, information leaks, and Man-in-The-Middle attacks. Windows devices are vulnerable to the Man-in-The-Middle attack. Linux devices running BlueZ are affected by the information leak vulnerability, and Linux devices from version 3.3-rc1 (released in October 2011) are affected by the remote code execution vulnerability (This includes many smart watches, smart tvs, and smart refrigerators). iPhone, iPad and iPod touch devices with iOS 9.3.5 and lower, and AppleTV devices with version 7.2.2 and lower are affected by the remote code execution vulnerability, but this vulnerability was already patched for users running iOS 10. Even networks that are “air gapped” are at risk of this attack, and includes industrial systems, government agencies, and critical infrastructure.

Examples of attacks:

  • Taking a picture on a phone and sending it to the hacker
  • Listening to a conversation through a wearable device
  • Redirecting a user to a fake login page to steal their login information
  • Cyber espionage
  • Data theft
  • Ransomware
  • Creating large botnets out of IoT devices

Many companies are pushing out updates for their users, but for many it is too late, and for others they have older devices that will not receive the updates.

As of 9/13/17:

  • Apple users with iOS 10 are safe
  • Google has released a patch for this vulnerability for Android Marshmallow and Nougat, but it might be weeks before the patch is available to some Android users
  • Microsoft patched the vulnerabilities in July
  • A patch for Linux is expected to be released soon

The problem is that even with these patches, there are many users who are unaware of this exploitation and/or do not update their devices regularly. For users that haven’t updated their devices or do not have an update for their device, the safest thing to do is to turn Bluetooth off on your phone and leave it off until there is a patch for your device
