"Ransomware Trojan Horse" will be the main trend of the virus this year

According to an antivirus expert: Cybercriminals are shifting from methods that once used large-scale attacks on businesses to encrypting their data, and then asking companies for ways to decrypt costs. According to the head of Kaspersky Lab, Eugene, speaking at the RSA Conference on Tuesday, local time: The so-called "ransomware Trojans (trojan horses)" will become a major trend in 2007.

This virus software can infect PCs, encrypt some data, and then send warning messages to users, telling these PC-infected users to spend money to obtain the keys needed to re-access these data. Malware like this is not a new discovery. Cryzip discovered in March 2006 and GPCode discovered in May 2005 belong to this category. Although Cryzip and GPCode did not cause large-scale losses to users at that time, however, according to Eugene, computer criminals will further increase their ability to use "Trojan Horses for Ransomware" this year.

According to Eugene: The latest version of GPCode uses a 660-bit encrypted password. It takes a powerful PC to run it for 30 years to crack it, but in fact Kaspersky quickly cracked this password. Eugene explained: This is because the hackers have not fully mastered the encryption technology, otherwise the anti-virus manufacturer will be unable to crack the password and restore the user's data.
