Alert: Ransomware are on the loose. Know what precautions you should take to prevent data loss
October 22, 2013

A few weeks back we had informed our readers about CryptoLocker – a new type of a ransomware that has been let loose on the Internet. This post discusses some more important facts about this malware, and steps you must take to prevent it from affecting your computer.

What is a Ransomware?
A ransomware is a malicious program that freezes or locks up the victim’s computer, and makes it nonfunctional. The malware demands the victim to pay up a certain sum of money (ransom) to unlock the compromised machine. Because of this nature of demanding money and releasing the hijacked computer, this program is known as ransomware. Some ransomware also work by encrypting all your documents and data files and ask for ransom to decrypt the same.

What is CryptoLocker?
CryptoLocker is a type of ransomware that is actively spreading on Internet. After it invades the targeted machine, it starts encrypting all kinds of files on the machine such as images, videos, documents, presentations and spreadsheets. Once it has encrypted the files, it reveals itself in the form of a pay page. The page informs the user that the files on their computer have been encrypted. To recover the files, the user must purchase a private key. The typical ransom demanded by the CryptoLocker is $300. Also, the user has a limited time period to pay up the ransom, after which the private key will be destroyed and the hijacked files will be lost forever.

Unfortunately, once CryptoLocker has encrypted your files, there is no way to recover them until you have the private key. So, should you pay the ransom? We would like to go with a resounding and bold NO.

You are dealing with outright criminals here, who are extorting money from you. And there is no saying if they will hand over your files even after you have made the payment. Of course, the data that you have lost may be crucial. But, you can lose you data in several other ways.

There is one good news though. The files that are encrypted by CryptoLocker, are not accessed by the hackers. The files remain where they are – on your system, but in an encrypted form.

How Can you Prevent a CryptoLokcer Catastrophe?
Nothing would fit the scenario of CryptoLocker than the saying, “Prevention is better than cure”. That’s right! The only way you can recover from a CryptoLocker attack is to take the right precautions way before time. For your easy reference, we have outlined them for you:

• Backup is important, but with nefarious malware like CryptoLocker around, it can be lifesaver. The malware directly goes for your personal and important files. So, the loss of such files can only be managed with regular backups. Take backups of every file that is important to you and take the backup offline.

• Ensure that your computer is running an antivirus software that gives multilayered protection, and is always up to date. Understand the fact that, if your computer is already infected with a backdoor [a means of access to a computer program that bypasses security mechanisms], then it can be used by hackers to install CrytoLocker. So, using a reliable antivirus significantly reduces the risks of a CryptoLocker attack and that of other malware also.

• Same goes for your computer’s operating system, software, and browsers. Keep them patched and updated. This is another layer of precaution that you must take. Malware can gain entry into your computer via compromised websites, security holes in Internet browsers, and malicious software. And as mentioned, CryptoLocker only needs an existing malware in your system to make its entry.

• We strongly recommend you to avoid using administrator accounts for your daily work. A malware that attacks a high-privileged account can do irreparable damage. It is like somebody shooting you with your own gun that is fully loaded. Therefore, prefer using a typical user account (your gun that is empty or not fully loaded). For instructions on how to set up a new account with standard or low privileges, please follow these links, depending on the OS you are running: Windows 7, Windows Vista, Windows XP. [source: http://www.it.cornell.edu/]

• Because infected or compromised Web sites can also let CryptoLocker into your machine, it is a good idea to have the Sandbox protection feature. It is an advanced security feature formulated for safe browsing. Once the feature is activated, it takes your Internet browser into a virtual environment. While you browse inside the Sandbox, your PC’s operating system, memory locations, files, and other vital areas are screened away from the browser. So, even if any infection does take place, it will remain confined inside the virtual environment without affecting the real PC.

• CryptoLocker may also attack you in the form of email attachments. A simple way to avoid this risk, is to trash unsolicited and unwanted emails. Be particularly careful against unexpected emails that talk about lottery, unsent courier and those from banks and financial institutions.

Note: Recently we came across a new ransomware that goes by the name Anti-Child Porn Spam Protection. It states that the target’s computer is spamming links of child pornography Web sites. And it claims that it has encrypted the computer’s data, in order to protect the user, and others from such spams. This message is followed by their demand for a certain sum of money to get a password for recovering the data. Even in such cases, please do not pay any kind of money.

Given the increasing cases of ransomware and its variants, we urge our readers to strongly consider taking the precautionary measures listed in this post.

    May you tell me what is Sandbox ? Is it available on Quick Heal Total Security 2013 ? If yes, then how to enable this ?

    • Hi Prasant,

      Browser Sandbox protection is a special protection for your PC from malicious websites. This feature creates a virtual environment and executes your Internet browser within this environment inside your PC. When you are surfing the Internet through the browser that is executed in the virtual environment, it protects your real PC from any infection that your PC may catch from an infected or malicious website. You can read this post for more details on the Browser Sandbox feature.

      Yes, Quick Heal Total Security 2013 does provide the Browser Sandbox protection. To activate the feature, follow these steps:

      Open Quick Heal
      Click Internet & Network
      Find the Browser Sandbox option
      Turn it ON

      • I’m using Quick Heal Total Security 2013. But there is no option like “Browser Stand-box” in Internet and Network. All the options available in Internet and Network are:
        1. Firewall Protection
        1. Browsing Protection
        1. Malware Protection
        1. Phishing Protection
        1. News Alert
        And all of the above options are already turned on!

        Please tell me how to enable “Browser Standbox” now?

        • Hello Remo,

          On the Quick Heal dashboard, you will find the Internet & Network section.
          Click this section, and in the page that comes up, the second last option would be Browser Sandbox. You can then turn it ON if it is OFF.

          For any assistance with this, kindly contact our support team at 0-927-22-33-000.

          You can also raise a query at http://www.quickheal.com/submitticket.asp. Our support team will get back to you to resolve the issue you are facing.

    is it affecting windows 8? and quickheal total security is able to manage this problem?

    Reply
    • Hi Sagnik biswas,

      Yes, Windoews 8 is also vulnerable to CryptoLocker. Quick Heal detects this family of ransomware as Trojan.Crilock.A. Although it cannot recover any files encrypted by CryptoLocker, it can remove it from the infected machine. Keeping your Quick Heal updated, and taking preventive measure reduce the risk of this malware significantly.

    Can encryption of our drives prevent this Cryptolocker??Should we encrypt our files before such ransomware do???Is it possible fr such malware to re-encrypt our drives once we have totaly encrypted our drives f pc??

    Reply
    • Hi Sananda,

      It is a safe practice to encrypt all important files in your computer. However, it cannot be said for certain that doing so may prevent CryptoLocker from re-encrypting the files. For the time being, the best method is to take regular backups, and follow the precautionary measures such as the ones mentioned in this post.

    • Hi Gemar,

      At present, CryptoLocker only affects Windows PC. As mentioned in the post, CryptoLocker uses existing malware in targeted PCs. Keeping your Quick Heal updated will prevent all types of malware infection. And this reduces the risk of CryptoLocker attacking your PC. You can further reduce the risk, by following the precautionary measures we have listed down in the blog post. Also, Quick Heal detects this family of ransomware as Trojan.Crilock.A. Although it cannot recover any files encrypted by CryptoLocker, it can remove it from the infected machine.

    (1) You are exhorting us not to pay any money (ransom). Good, but even if we want, most Indians would not be able pay in dollars/euros/pounds because of remittance/currency restrictions. Payment by Indian Rupee cards are not accepted by American/European Banks. Payment from Indian Rupee Bank Accounts to foreign Banks dealing in dollars/euros/pounds are also not permitted.(2)Since the Robbers are getting the money through Bank accounts, are the Police of the related country/ies not able to catch them?–just a doubt!

    • Hi D. Suriyamoorthy,

      We have strongly recommended our readers not to pay any kind of money. So, the question of being able to pay in local or foreign currency should not arise in the first place. Cyber security officials are doing their job to nab the criminals. What we can do is follow the right preventive measures and stay alert.

    • Hi Vijay,

      Quick Heal Anti Virus for Windows server offers browser protection and firewall protection. Browser protection filters HTTP traffic coming from Web sites on the Internet. Firewall protection blocks malware from reaching the system. So, these two features when combined by the preventive measures mentioned in the post, should significantly reduce the threat of CryptoLocker.

    im a firefox user , and few months months ago while surfing the net, a green outline formed outside the border of my firefox browser. What could it be ?

    I went through a post by another user few weeks ago , and he experienced the same thing . And one of the quickheal guys replied to him, that its because the sandbox feature was turned on.

    So my question to you is , if its because of the sandbox feature that the green line is appearing around the browser, then why can’t i see any green line around my browser right now ??
    I mean , i just opened my quick heal and turned on the sandbox feature, yet i don’t see any green line around my browser . Please help me on this issue.

    Also i would like to know one thing , and that is , why quickheal is not providing any anti-rootkit feature for 64-bit systems ??
    I mean back in 2009 there was anti-rootkit in quickheal internet security, so why not Now for 64-bit systems?? Thanks.

    • Hi RedMonster,

      When Browse Sandbox is enabled, you must see a green border around the Internet browser. Browser Sandbox supports Internet Explorer, Mozilla Firefox, and Google Chrome.

      If your Browser Sandbox is ‘ON’ but the green border does not appear, then we advise you to contact our Technical Support Center at 0-927-22-33-000.
      You can also raise a query at http://www.quickheal.com/submitticket.asp. Our support team will get back to you to resolve the issue you are facing.

      In response to your second query, due to some technical limitations, Anti-Rootkit is not currently supported by 64-bit operating systems. We may release it in future.

      We are sorry to learn about this incident. Unfortunately, files that get encrypted by CryptoLocker cannot be recovered without the private key. However, Quick Heal can remove the malware from your system. Kindly contact our support team at 0-927-22-33-000 for any assistance.

  61. Yeah everything looks fine.
    you said it encrypts the file and ask for money and you say not to give them the money.
    Then how can someone get back the files.
    Tell me any way to handle such issue after it has occurred.

    • Hi Kamlesh,

      Any file, once encrypted by CryptoLocker cannot be recovered, unless the private key is obtained. And we have recommended our readers not to pay any kind of money demanded by the malware, because it is not certain that the malware author would oblige and hand over the private key. As mentioned in the post, the best way to deal with a CryptoLocker is to prevent it from attacking your system. And we have discussed in this post how you can do so.

      Regards,

  64. Recently when I started my PC for first time in morning.; it went(directly) to native (boot) scan WITHOUT me having chosen that option…during that scan it detected Trojan WD.cw6 and deleted it !!!
    Is QH so sophisticated that when it detects PC not starting correctly it goes on Auto Boot scan ?? !!!
    Remarkable product and Desi too !!!

      Unfortunately, files that are encrypted by CryptoLocker cannot be recovered without the private key, as mentioned in the post. If you have a backup of all these files, then you can recover them from the same. We would like to inform you that the Quick Heal 2014 series can detect and remove 90% of CryptoLocker samples. If you wish to receive a free upgrade, then please follow this link – http://www.quickheal.com/upgrade/

    Recommending a bold NO is dumb. If a business has its operational database and quickbooks files locked, you suggest just letting it go?

    While I agree backing up is the best method, but it doesn’t help when your backup is also locked.

    Maybe try a post that actually helps..

    • Hi Commenter,

      As we have mentioned, there are several other ways any organization can lose its data. It is true that letting go of the data encrypted by the CryptoLocker can be detrimental. But the bigger question is, “Can we trust criminals?” There is no silver bullet for ransomware. The best we can do is taking regular backups offline and storing them away in a safe place, and follow basic preventive measures such as the ones described in the post.

      Regards,
