Telnet, UPnP and SMB site visitors

The most important percentage of site visitors all over H1 2019 was once led by means of Telnet with over 760m assault occasions logged or round 26 % of site visitors. UPnP was once the following maximum widespread with 611m assaults adopted by means of SSH, which could also be used to focus on IoT gadgets, at 456m assaults.


IoT gadgets which have been inflamed with malware akin to Mirai are most likely assets of this site visitors as Mirai was once the most typical malware circle of relatives seen by means of F-Safe’s honeypots. Mirai objectives and infects routers, safety cameras and different IoT gadgets which use manufacturing facility default credentials.

F-Safe additionally discovered that site visitors to SMB port 445 accounted for 556m assaults. The prime stage of SMB site visitors signifies that the Everlasting circle of relatives of exploits, which have been first utilized in 2017’s WannaCry ransomware outbreak, are nonetheless being utilized by cybercriminals taking a look to focus on thousands and thousands of machines that experience now not but been patched.

Major researcher at F-Safe, Jarno Niemal equipped additional perception at the record’s findings, announcing:

“3 years after Mirai first gave the impression, and two years after WannaCry, it presentations that we nonetheless haven’t solved the issues leveraged in the ones outbreaks. The lack of confidence of the IoT, for one, is handiest getting extra profound, with an increasing number of gadgets cropping up always after which being co-opted into botnets. And the job on SMB signifies there are nonetheless too many machines in the market that stay unpatched.”
