If you travel with your laptop, you are going to want data encryption to protect your privacy and important files in the event that your laptop is lost or stolen. With 16,000 laptops lost or stolen in International airports every week, business travelers need data encryption more than ever. Dell's Laptop Data Encryption is a SaaS (Software As A Service) cloud-based service that automatically encrypts your important data. Security is a top concern for today's businesses and Dell's Secureworks and Laptop Data Encryption technologies have made the company a leader in information security and threat protection.

CryptoLocker was a ransomware trojan which targeted computers running Microsoft Windows and was first observed by Dell SecureWorks in September 2013. CryptoLocker propagated via infected email attachments, and via an existing botnet; when activated, the malware encrypts certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware's control servers. The malware then displays a message which offers to decrypt the data if a payment (through either Bitcoin or a pre-paid cash voucher) is made by a stated deadline, and threatened to delete the private key if the deadline passes. If the deadline is not met, the malware offered to decrypt data via an online service provided by the malware's operators, for a significantly higher price in Bitcoin. Although CryptoLocker itself is readily removed, files remained encrypted in a way which researchers considered infeasible to break. Many said that the ransom should not be paid, but did not offer any way to recover files; others said that paying the ransom was the only way to recover files that had not been backed up. Some victims claimed that paying the ransom did not always always lead to the files being decrypted. This video is targeted to blind users.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Operation Tovar is an international collaborative operation carried out by law enforcement agencies from multiple countries against the Gameover ZeuS botnet, which is believed by the investigators to have been used in bank fraud and the distribution of the CryptoLocker ransomware. Participants include the U.S. Department of Justice, Europol, the FBI and the U.K. National Crime Agency, South African Police Service, together with a number of security companies and academic researchers, including Dell SecureWorks, Deloitte Cyber Risk Services, Microsoft Corporation, Abuse.ch, Afilias, F-Secure, Level 3 Communications, McAfee, Neustar, Shadowserver, Anubisnetworks, Symantec, Heimdal Security, Sophos and Trend Micro, and academic researchers from Carnegie Mellon University, the Georgia Institute of Technology, VU University Amsterdam and Saarland University. Other law enforcement organizations involved include the Australian Federal Police; the National Police of the Netherlands' National High Tech Crime Unit; the European Cybercrime Centre (EC3); Germany’s Bundeskriminalamt; France’s Police Judiciaire; Italy’s Polizia Postale e delle Comunicazioni; Japan’s National Police Agency; Luxembourg’s Police Grand Ducale; New Zealand Police; the Royal Canadian Mounted Police; and Ukraine’s Ministry of Internal Affairs' Division for Combating Cyber Crime. The Defense Criminal Investigative Service of the U.S. Department of Defense also participated in the investigation. In early June 2014, the U.S. Department of Justice announced that Operation Tovar had temporarily succeeded in cutting communication between Gameover ZeuS and its command-and-control servers. The criminals attempted to send a copy of their database to a safe location, but it was intercepted by agencies already in control of part of the network. Russian Evgeniy Bogachev, aka "lucky12345" and "slavik", was charged by the US FBI of being the ringleader of the gang behind Gameover Zeus and Cryptolocker. The database indicates the scale of the attack, and it makes decryption of CryptoLocked files possible. In August 2014 security firms involved in the shutdown, Fox-IT and FireEye, created a portal, called Decrypt Cryptolocker, which allows any of the 500,000 victims to find the key to unlock their files. Victims need to submit an encrypted file without sensitive information, which allows the unlockers to deduce which encryption key was used. It is possible that not all CryptoLocked files can be decrypted, nor files encrypted by different ransomware. Analysis of data which became available after the network was taken down indicated that about 1.3% of those infected had paid the ransom; many had been able to recover files which had been backed up, and others are believed to have lost huge amounts of data. Nonetheless, the gang was believed to have extorted about US$3m.

CryptoLocker is a ransomware trojan which targets computers running Microsoft Windows and first surfaced in September 2013. A CryptoLocker attack may come from various sources; one such is disguised as a legitimate email attachment. When activated, the malware encrypts certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware's control servers. The malware then displays a message which offers to decrypt the data if a payment is made by a stated deadline, and threatens to delete the private key if the deadline passes.
