Because Windows Defender comes with all the newer versions of Windows operating systems, no cyber-security company can ever dream of having an image of today's malware scene, as Microsoft does.
As the year ends, we read it report securityMicrosoft to get an idea of what happened to malware and the security front for Windows users of 2019.
According to data compiled by Microsoft, the number of ransomware, cryptominers and malware scans - as a whole - has dropped this year, compared to the same period last year or even the last two years.
“Some possible reasons for the overall decline in malware encounters in 2018 [and 2019] are the increase in adoption of Windows 10 and its increased use Windows Defender for protection, ”Microsoft said.
Both Windows 10 and Windows Defender have received significant security enhancements over the past five years, improvements that make malware campaigns less efficient when targeting modern Windows 10 systems.
According to the table below, Microsoft says the number of Windows machines detected as malware has been reduced from 6-7% of the total ecosystem of Windows at the beginning of 2017 to 4,15% in October of 2019.
A similar decline was also observed for cryptominers - malware that specializes in mining encryption without the consent or knowledge of users - which were particularly popular in crooks the 2017.
According to Microsoft data, this decline began in January at 2018, when crawls reached 0,3% of all Windows systems and then slowed to a low today's 0,09%, recorded in October at 2019.
Ransomware detections also fell into a similar pattern, reducing their detection in January of 2018 to 0,11% of all Windows systems to a low 0,04% in October of 2019.
The fall is in line with what has been reported elsewhere by many security researchers - that ransomware gangs have abandoned end-users (home users, consumers, regular users) and have moved in the direction of business networks, where they can request more ransom than they could ask from a regular user.
So while the scans are low, that doesn't mean the ransomware is dead. In fact, ransomware has been a scourge for service administrators, US schools, local governments this year. USA and, more recently, for the European business scene, causing huge financial losses themselves, but affecting fewer users overall.
The company notes that while the number of malware detection has decreased in the last two years, but malicious campaigns have not stopped completely.
According to the Microsoft Security Report, the criminal gangs at cyberspace have responded by modifying "modus operandi", moving on activities that do not involve use malware - As the Phishing, the attacks DDoS and stuffing credentials.
For example, Microsoft stated that the percentage of emails identified as phishing attempts increased from 0,2% in January to 2018 to about 0,6% in October to 2019, while the size of average TCN-based DDoS attacks increased from 75 Gbps in May over 200 Gbps October of this year.
Microsoft has found that more than 44 millions of users are reusing it passwords, putting their respective accounts at risk of hacking through a technique known as credential stuffing.
