More than 500 million digital identities were stolen or exposed in 2015, suggests a report from security firm Symantec.
In addition, it said, fake technical support scams rose by 200% and crypto-based ransomware attacks grew by 35%.
Hackers also made more use of unknown software bugs to make sure attacks work, said the annual threat report.
It said the gangs behind the attacks had become more professional and now resembled legitimate software firms.
“They have extensive resources and highly skilled technical staff that operate with such efficiency that they maintain normal business hours and even take the weekends and holidays off,” said Kevin Haley, director of Symantec security response in a statement.Posted by Calibre Web Team Posted on 13 Apr
