McAfee released its McAfee Labs Threats Report: June 2018, examining the growth and trends of new malware, ransomware, and other threats in Q1 2018. McAfee Labs saw on average five new threat samples every second, including growth in cryptojacking and other cryptocurrency mining malware, and notable campaigns demonstrating a deliberate drive to technically improve upon the most sophisticate established attacks of 2017.
“There were new revelations this quarter concerning complex nation-state cyber-attack campaigns targeting users and enterprise systems worldwide,” said Raj Samani, chief scientist at McAfee. “Bad actors demonstrated a remarkable level of technical agility and innovation in tools and tactics. Criminals continued to adopt cryptocurrency mining to easily monetize their criminal activity.”
Cybercriminals extended their operations in cryptojacking and other cryptocurrency mining schemes, where perpetrators hijack victims’ browsers or infect their systems to secretly use them to mine for legitimate cryptocurrencies such as Bitcoin. This category of coin miner malware grew a stunning 629% in the first quarter of 2018, rocketing from around 400,000 total known samples in Q4 2017 to more than 2.9 million the next quarter. This suggests that cybercriminals are continuing to warm to the prospect simply infecting users’ systems and collecting payments without having to rely on third parties to monetize their crimes.
“Cybercriminals will gravitate to criminal activity that maximizes their profit,” said Steve Grobman, chief technology officer at McAfee. “In recent quarters we have seen a shift to ransomware from data-theft, as ransomware is a more efficient crime. With the rise in value of cryptocurrencies, the market forces are driving criminals to crypto-jacking and the theft of cryptocurrency. Cybercrime is a business, and market forces will continue to shape where adversaries focus their efforts.”
