Top ten viruses - April 2005.A report compiled from Sophos's global network of monitoring stations, shows that Zaft-D, which first appeared at the end of 2004, continues its reign at the top of the list for the fifth month running, accounting for 46.6% of all reports. Only one new threat--Mytob-Z--has managed to break into the chart for April, appearing in seventh place. The top ten viruses in April 2005 were as follows: 1. W32/Zafi-D 46.6% Fifth Month at Number 1 2. W32/Netsky-P 20.6% 3. W32/Zafi-B 4.5% 3. W32Netsky-D 4.5% 5. W32/Netsky-Z 2.5% 6. W32/Netsky-B 2.4% 7. W32/N4ytob-Z 1.3% New Entry 8. W32/MyDoom-O 1.2% 9. W32/Netsky-C 1.1% 10. W32/Netsky-Q 1.0% Others: 14.3% Comment: Old viruses are still taking advantage of poorly protected computers in April. The Zafi family of viruses accounts for over 50% of all the viruses reported to Sophos in the last month. Perhaps the success of these worms lies in their ability to spread in multiple languages, catching out unwary users all over the world. Although Mytob-Z only accounts for a required a DESkey USB Token An authentication token that plugs into the USB port of a computer. See authentication token. to operate, DESlock+ Version 3.00 now supports a software Key -File as a low cost alternative, and has been designed to allow transparent encryption of emails, files, folders and other information across the network and includes: and plug-in components for Microsoft Outlook For the e-mail and news client bundled with certain versions of Microsoft Windows, see . Microsoft Outlook or Outlook (full name Microsoft Office Outlook and Lotus Notes Messaging and groupware software from IBM Lotus that was introduced in 1989 for OS/2 and later expanded to Windows, Mac, Unix, NetWare, AS/400 and S/390. Notes provides e-mail, document sharing, workflow, group discussions and calendaring and scheduling. , DESlock+ minimises the steps required to work with encrypted data and email. Where previous versions have required a DESkey USB Token to operate, DESlock+ Version 3.00 now supports a software Key -File as a low cost alternative, and has been designed to allow transparent encryption of emails, files, folders and other information across the network and includes: * Hardware or software keys DESlock+ 3.00 works with either a licensed software key-file or a DESkey USB Token * AES, Triple DES See DES. (cryptography) triple DES - A product cipher which, like DES, operates on 64-bit data blocks. There are several forms, each of which uses the DES cipher 3 times. Some forms use two 56-bit keys, some use three. The DES "modes of operation" may also be used with triple-DES. and Blowfish A secret key cryptography method that uses a variable length key from 32 to 448 bits long. It uses the block cipher method, which breaks the text into 64-bit blocks before encrypting them. algorithms are used for high-speed, data encryption data encryption, the process of scrambling stored or transmitted information so that it is unintelligible until it is unscrambled by the intended recipient. Historically, data encryption has been used primarily to protect diplomatic and military secrets from foreign with RSA (1) (Rural Service Area) See MSA. (2) (Rivest-Shamir-Adleman) A highly secure cryptography method by RSA Security, Inc., Bedford, MA (www.rsa.com), a division of EMC Corporation since 2006. It uses a two-part key.
