Ransomware levels have soared by more than 120% over the past year as hackers grow ever more determined and attacks are carried out on an industrial scale, according to Intel Security.
The firm’s McAfee Labs Threats Report August 2015 marks five years since the chip giant first signaled its intent to acquire the security giant.
It revealed that the number of new ransomware samples rose 58% from the first three months of the year to Q2 2015, while the figure rocketed to 127% year-on-year.
The rise is attributed to fast-growing malware families including CTB-Locker and Cryptowall. Virtual currencies like Bitcoin and anonymizing networks such as Tor have helped the cyber-criminals stay hidden from law enforcement – “making it commercially viable and spurring unexpectedly high growth.”
The report continued:
“Another indicator of cybercrime business maturity has been the drop in technical skills required to participate in the industry. Off-the-shelf toolkits for malware, affiliate programs for ransomware, fill-in-the-blank attack-creation programs, and other familiar business offerings have been showing up in the dark web to support faster, simpler and broader distribution of attacks. It now takes very little skill to be a cyber-criminal.”
Other notable Q2 stats in the report include 6.7 million attempts every hour to trick Intel Security customers into connecting to “risky” URLs.
In addition, every hour more than 19.2 million infected files were exposed to customers’ networks, while seven million Potentially Unwanted Programs (PUPs) attempted to install or launch.
But it wasn’t all bad news. Although the number of mobile malware samples grew 17% in Q2, mobile malware infection rates dropped around 1% during the quarter, 4% in North America, McAfee Labs said.
In fact, the firm’s EMEA CTO, Raj Samani, admitted that despite surging growth in the number of devices on the market, most new malware samples discovered over the past year have had a relatively low impact.
