Malware like CryptoLocker can enter an un protected network through many possibilities, including email, file sharing sites, and downloads. The rise of ransomware means the total cost of damages related to attacks using cryptographic file-locking software will continue to increase as long as companies are paying the ransom.

Hackerpocalypse: A Cybercrime Revelation , suggests that individuals and organizations who feel they have no choice but to pay a fee to unlock their files have lead to the increasing rise of ransomware. If its working, it will continue just like anything else. In the end, good backup and a disaster recovery plan and return to operations is the most effective defense.

Disaster recovery planning is crucial to safe business operations. A disaster recovery plan is the steps taken before, during, and after a disaster. Defending against ransomware requires IT planning, certified technologists, and involvement from everyone at your company to be truly successful. Not quite. So how did CryptoLocker spread? To help it infect additional victims, the cybercriminals behind it made use of the now-notorious Gameover ZeuS botnet.

In other words, it was a readymade audience for a massive CryptoLocker ransomware infection. In mid, an international task force known as Operation Tovar finally succeeded in taking down Gameover ZeuS. CryptoLocker uses an asymmetric encryption method that makes it difficult to crack. This two-key system uses one public key for encryption and one private key for decryption, each linked to the other.

The sender encrypts a file with the public key , and the recipient decrypts it with their private key. When asymmetric encryption is used for above-board purposes, such as transmitting sensitive information, the receiver will give the public key to the sender so they can encrypt the data, but keep the private key to themselves. With ransomware like CryptoLocker, the operators hold onto both keys, including the private key that you need to decrypt your files.

As soon as the encryption process is complete, CryptoLocker makes its presence known with a ransom note. Note how the ransom note above actually instructs victims to re-download the malware in the event their own antivirus deleted it. To remove CryptoLocker from your computer, all you need to do is fire up a trusty antivirus program, such as Avast Free Antivirus. They may instead elect to abscond with your money, leaving you both poorer and still without your files.

Paying ransoms sends the message that using ransomware to extort people is a viable and profitable pursuit. Never pay a cybercriminal to recover your files. Instead, the most reliable way to recover your files is by restoring them from a backup. But first, remove the ransomware from the infected device:. How to remove ransomware from PC. How to remove ransomware from Mac. How to remove ransomware from iPhone.

How to remove ransomware from Android. Instead, and as described above, your best bet is to remove the ransomware and restore your files from a backup, if you have one. If not, do not delete your files! Due to its resounding success, the CryptoLocker name and a family of variations on this theme has been used by several other instances of ransomware.

CryptoWall, first appearing in , infects Windows 10 in addition to older editions. It was so successful that in , an FBI agent admitted that in many cases, the agency actually encouraged victims to pay the ransom in order to recover their files — the debateable soundness of this advice notwithstanding.

CryptoLocker can only encrypt the files and folders to which its user account has access. Though when it comes to protecting your personal computer, this CryptoLocker prevention strategy is not likely to have any relevance. Instead, be sure to always follow these anti-ransomware best practices to prevent CryptoLocker and other ransomware from infecting your computer:.

Back up your data. This tip comes first because it is the single most effective way to recover your files in the event that you get hit with ransomware. If you use an external drive, disconnect it after the backup is complete and store it in a safe place. If you leave it connected to your computer, the ransomware can encrypt it as well. You can and should also back up to cloud services.

Never download attachments from unknown senders. Aside from the Gameover ZeuS botnet, this is how CryptoLocker made its way onto the computers of its victims. No matter what, never download unknown attachments. The same advice applies here as to the above tip. Not only in emails, but on the internet as well, especially in comment sections and forums. The links may lead to malicious websites that automatically download malware, including ransomware, to your computer.

Download programs, apps, and content from verified sources. P2P file sharing can be a tempting method for obtaining the content you want, but you do so at your own risk. Always update your software. These often eliminate vulnerabilities that cybercriminals can otherwise exploit to get their malware onto your computer. Limit the personal information you give away or put online. The more of your personal info a cybercriminal has, the more accurately they can tailor a phishing attempt to you.

Be an active participant in maintaining your online privacy. Use security software.
