Android Users: Specially for you. Be alert

This is specially for all Android users, because now a days android is so popular so attackers targeted this mobile operating system. Guys be secure and safe while accessing through your mobile phones. Read furthermore to secure your privacy. :)


Android user be safe

In Android phone, more malware distributed through mobile ad networks. You are confusing what is mobile ad network? Answer is : Advertising network or Ad network is a company that connects advertisers to publishers or web sites that want to host advertisement. Examples are - AdBuddiz, admob etc.

Mobile ad-network can provide a loophole to serve malware to Android devices, according to researchers from security firm Palo Alto Networks who have found new Android threats being distributed in this manner. That's is vulnerable for the surfing.

Most mobile developers embed advertising frameworks into their applications in order to generate revenue. Unlike ads displayed inside Web Browsers, ads displayed within mobile apps are served by code that's actually part of those applications. (Generate revenue through the ads display as well as the number of visitors).

The embedding of code for the advertising network into a mobile application itself ensures that ads get tracked and the developers get paid, but at the same time the third-party code represents a backdoor into the device, said Wade Williamson, senior security at Palo Alto Networks.

"If the mobile ad network turns malicious, then a completely benign application could begin bringing down malicious content to the device" Williamson said. There are precedents for this type of attack.  In April, mobile security firm Lookout identified 32 apps hosted on Google Play that were using a rogue ad network later dubbed BadNews. The apps were benign, but the malicious ad networks was designed to push all fraud malware targeting Russian speaking users through this apps.

In Asia, similar type of attack involved using a rouge ad network to push malicious code through other apps without being detected by mobile antivirus vendors.

The malicious payload pushed by the ad network runs quietly in the device memory and waits for users to initiate the installation of any other application. At this time, it prompts users to also install and grant permissions to the malware, appearing as if it's part of the new application's installation process.

This is very decent approach where end users does not need to do anything wrong. Once the malware installed, is has ability to interact and hide received text messages, as well as to send text messages in order to sign up users for premium rate mobile services, Palo Alto Networks said in a description of the attack sent via email.

Bogdan Botezatu, a senior e-threat analyst at antivirus vendor BitDefender, said that, this malware is based upon geographical region. They also expects the distribution through mobile ad-network to become more common, especially in countries where mobile devices can't access the official GooglePlay store or where users have difficulties in purchasing applications in a legitimate manner, casing most Android device to be configured to accept APKs(Android Application Packages) from unknown sources.

Google Play checks APKs for malware before approving them, so getting an infected APK uploaded there can be very hard, Botezatu said. Continue with their thought that users are more likely to fall victim to "malvertising" --malicious advertising --attacks launched through mobile apps than Web browsers. 

So, Android users should make sure that their devices are not configured to allow the installation of apps from unknown sources and should run a mobile antivirus product, which might be able to detect malicious apps delivered through ad networks.

Tips :
1) Don't install app outside the Google Play store
2) Always install antivirus.
3) Clear your browser cache memory (Your surfing data store into this memory)
4) Don' install other app store which allows malware app to be installed.
5) Before installing apps check it out properly.

Be Alert: Google Chrome exposes Users Password

Hello Every One, Be alert while saving your password into "Google Chrome". Google Chrome browser displays user password in plain text in its setting.

Google is taking some serious hear for the way Chrome can reveal all your saved passwords to anyone with access to you computer. Yet Google has defended the move, with Chrome's security tech lead arguing that further password protection measures would only provide a "false sense of security".

The issue has to do with the way Chrome stores passwords that the user has decide to save. So, now be aware of this while saving your password. Because hacker may interest the bug and can take the control of your account. All of these passwords are the listed in chrome://settings/passwords. Clicking on a password in this list, and then clicking the "Show" button, exposes the password in the plain text. You can test it. (Just type chrome://settings/passwords in your address bar and click on show password).

This isn't a new "feature" (in a language of taunt) of Chrome, but it was brought to light recently by "Software Developer Elliot Kember".
"[users] don't " expect it to be this easy to see their passwords (password can be stored in any other or its on encoding/decoding pattern)," Kember wrote in a blog post. "Every day, millions of normal, every-day users are saving their password in Chrome. So, if password is revealed or exposed it can not be acceptable."

Justin Schuh, head of the Chrome Security, defended the practice, saying that if someone has access to your computer and OS-level account, your security is already compromised. (In my opinion, everyone is not able to crack the code or find out your password. Totally disagree with their point). At that point, Schuh said and attacker could install malware at the system level or access other sensitive data. "Beyond that, however, we've found that boundaries within the OS user account just aren't reliable, and are mostly just theater," Schuh wrote.

Schuh has a point in terms of fending off serious attackers. But what about causal snooping --say (by infoworld), by an untrustworthy friend, sibling, spouse or co-worker? It seems unlikely that any of those users would go so far as to install malware, but a quick glance at someone's facebook or Twitter password doesn't seem out of the question, Schuh doesn't  address that point.

Here's the other problem with Schuh's logic: He sees Chrome merely as Software that exists within another operating system. But increasingly, Chrome is an operating system within an operating system, hosting troves of sensitive data in Web apps like Dropbox and Google Drive. Someone with brief access to your computer might be able to glace at these apps, but someone with your password could continually monitor your accounts from any other machine. Chrome makes it easy for the people near you to get these passwords.

Important: You can prevent this Just Do following steps.

If any of this sounds disturbing, you have a couple of option,
First => You can avoid saving passwords in Chrome by going to Settings > Advance Settings and unchecking the "Offer to save Passwords" box under "Passwords and forms". Click "Manage saved passwords" to its right to dive in and clear out all the password Chrome has saved already, or just to see this "vulnerability" in action.

If you hate re-entering passwords, consider using a password managers tool, or you could sing in to Websites using Google, Facebook or Twitter authentication when possible --  though that opens a new can of worms if someone malicious manages to seize your social media profile. The other option is to  "Disconnect your Google account" in Chrome's settings whenever you are letting someone else borrow your computer.

Ideally,though, Google should just add another sign in requirement when a user tries to view password. That won't stop a hacker to access to your PC, but it'll keep out prying eyes at no major expense to user. Firefox, which would also display passwords in plain text, gives users a "Master  Password" option that does just that -- though only if you take the time to set up the feature.
