Here’s the second timeline of May covering the main cyber attacks occurred in the second half or the month (first timeline here).
The month of May 2017 will be remembered in the Infosec memory for the outbreak of WannaCry, which has overshadowed another remarkable event like the hack of Zomato, with 17 million accounts ending up for sale in the black market.
The second half of May has also confirmed the sustained activity of Russian hackers in the cyber space. Alleged malicious actors from Russia are behind another attack against energy networks of the Baltic States, a campaign carried on via malware laced Twitter messages against the US Department of Defense, a hacking and disinformation campaign against more than 200 gmail users (a campaign orchestrated by APT28 and called Tainted Leaks), and an attack against the Trump Organization.
Scroll down the rest of the list to have an idea of all the events happened in May, and if you want to have an idea of how fragile our electronic identity is inside the cyberspace, have a look at the timelines of the main Cyber Attacks in 2011, 2012, 2013, 2014, 2015 and 2016 (regularly updated).
