Because of the COVID-19 pandemic, the use of remote access technologies such as RDP and VPN is growing rapidly, because many companies have transferred their employees to remote work, and this usually involves a remote connection to internal networks.
By Shodan Search Engine Statistics, last Sunday, March 29, 2020, the number of RDP endpoints increased from 3,000,000 at the beginning of the year to almost 4,400,000. This data includes only endpoints running on the standard RDP 3389 port.
However, Shodan founder and CEO John Matherly writes that a similar surge in activity is also seen on port 3388, which is regularly used by system administrators to hide RDP from attacks. According to Motherly, in this case, activity increased by 36.8% (from 60,000 at the beginning of the year to 80,000 now).
Similarly, the number of different servers using VPN protocols is growing, such as IKE and PPTP: from 7,500,000 to almost 10,000,000 to date.
However, these figures reflect the situation only with corporate VPN servers, while the use of consumer-level VPNs is also growing rapidly. The fact is that since most users are now stuck at home, they are increasingly resorting to using VPN applications to bypass geographic blocking. For example, last week, NordVPN developers reported that since March 11, the number of users increased by 165% while Atlas VPN says about increased use VPN at 124% only among users from the United States.
These data are also confirmed by representatives of the Top10VPN website, which note the growth of the entire market as a whole and, in particular, record 65% increasee Demand for VPN in the US (compared to last quarter).
