| Computer users face hard choice _ pay ransom or lose files | |

NEW YORK (AP) -- It's a chilling moment: A message appears on a computer screen, saying the files are encrypted and the only way to access them is by paying a ransom. It happened at Jeff Salter's home health care business last December. The network of nearly 30 computers at Caring Senior Service was infected with ransomware, malicious software that hackers use to try to extort money from people and businesses by preventing them from opening or using documents, pictures, spreadsheets and other files. If computer users don't pay, there's no way they can access their files. Ransomware is one of the fastest-growing forms of hacking, cybersecurity experts say. Anyone from a home computer user to a Fortune 500 company can be infected. It can also attack smartphones. The smaller the users, the more vulnerable they are to losing their files — unless they have a secure backup for their system or go through the complicated process of paying cybercriminals. Salter thought he was prepared for such an invasion. Most of his files were backed up in a place hackers couldn't access, and he was able to restore his information. But one machine wasn't; it contained marketing materials for his San Antonio-based franchise chain with 55 locations. Salter paid a $500 ransom. "It would have cost us $50,000 to try to spend the time to recreate the stuff," Salter says. "It would have been pretty devastating if we'd lost all that." EVERYONE'S AT RISK Like many hackers' tools, ransomware can arrive in emails with links or attachments that, when clicked on, unleash software into files. Attacks can also occur when users visit websites; cybercriminals can attach computer code even to well-known sites operated by tech-savvy companies, says technology consultant Greg Miller of CMIT Solutions of Goshen, New York. |
