Q2 2018 news includes: non-standard use of old vulnerabilities, new botnets, the cutthroat world of cryptocurrencies, a high-profile DDoS attack (or not) with a political subtext, the slashdot effect, some half-baked attempts at activism, and a handful arrests.
Technical discovery of note is the potential for creating botnets using the UPnP protocol; although evidence for them exists, they are still extremely rare in the wild, fortunately.
Windows botnet activity decreased: in particular, Yoyo activity experienced a multifold drop, and Nitol, Drive, and Skill also declined. Meanwhile, Xor for Linux significantly increased its number of attacks, while another infamous Linux botnet, Darkai, scaled back slightly. As a result, the most popular type of attack was SYN flooding.
The total attack duration changed little since the previous quarter, but the share of medium-duration attacks increased, while the share of shorter ones decreased. The intensity of attacks also continues to grow. The most lucrative targets for cybercriminals seem to be cryptocurrencies, but we can soon expect to see high-profile attacks against e-sports tournaments as well as relatively small ransoms targeting individual streamers and players. Accordingly, there will be market demand for affordable individual anti-DDoS protection.
