| Ransomware increased 58% in Q2, according to McAfee. |
The number of samples of ransomware has increased 127% in the last year and only 58% in the second quarter of 2015, according to the latest report from McAfee Labs Threat. This August the fifth anniversary of the announcement of the acquisition of McAfee is held by part of Intel; so in addition to presenting new data, the report includes a retrospective about the way the current threat landscape meets the expectations of five years ago.
McAfee attributes the enormous increase in samples of ransomware to the proliferation of new families as CTB-Locker and CryptoWall, the FBI claims to cost US citizens $ 18 million, approximately a year.
Some variants are specifically ransomware behind mobile devices. The mobile malware samples increased 17%, the report said, but rates of infection by malware for these devices decreased slightly because fell 4% in North America, they were unchanged in Africa and fell about 1% in all other regions.
In his retrospective of the past five years, the report's authors said that although the volume of mobile devices has increased more rapidly than anticipated, the evolution of "broad-based serious attacks" these devices has been giving less intense what they expected.
Some reasons for the delay, they wrote, could be that mobile devices are not prominent attack vectors for business, the value of the data stored in them is relatively low and common automatic backup capabilities offered by many mobile devices often facilitate remove contents and recover lost files.
But with that exception, the researchers note that the picture of attacks has grown at a faster rate than they thought. "Although we expected and we anticipate most of this growth, the rapid evolution of malware, the increase in the volume of large-scale attacks and attacks by nation states have been amazing," they say in the document.
Seeing future, they argue that "it is only a matter of time" before the devices based on the Internet of Things (IOT, for its acronym in English) a common target of attacks become (more specifically, data or capabilities gateway they own). McAfee researchers say the volume of IoT devices and the number of industries that are expected to expand are also higher than they had anticipated.
The report also delved into the subject of malware operating in the GPU, which has received renewed attention earlier this year when Team unveiled Jellyfish proof of concept code for a key logger, rootkit and a remote access Trojan They are operating in the GPU.
The appeal of malware for the GPU has been that it is supposedly more difficult to detect and more persistent as though the files hosts are removed from the CPU, the malware persists after a warm restart and does not have tools for effective security analyze the GPU.
"Threats to the GPU is a real concern. But this type of attack has not attained the status of perfect storm, "the report said.
Although reverse engineering and forensics malware GPU is much more challenging, researchers say the process of infecting the GPU through the CPU leaves evidence of an attack (even if the initial code is eliminated in the CPU) so that specific security tools that operate on the CPU might well detect these threats.
