Meet the Worlds Biggest Bulletproof Hoster

krebsonsecurity.com/2019/07/meet-the-worlds-biggest-bulletproof-hoster/ In a talk given at the Black Hat security conference in 2017, researchers from cyber intelligence firm Intel 471 labeled Yalishanda as one the top tier bulletproof hosting providers worldwide, noting that in just one 90-day period in 2017 his infrastructure was seen hosting sites tied to some of the most advanced malware contagions at the time, including the Dridex and Zeus banking trojans, as well as a slew of ransomware operations.. His current bulletproof hosting service is called Media Land LLC. This finding is supported by documents maintained by Rusprofile.ru, which states that an Alexander Volosovik is indeed the director of a St. Petersburg company by the same name.. However, occasionally big-time bulletproof hosters from those CIS countries do get disrupted and/or apprehended. On July 11, law enforcement officials in Ukraine announced theyd conducted 29 searches and detained two individuals in connection with a sprawling bulletproof hosting operation.. [Upcoming paper on this, Platforms in Everything: Analyzing Ground-Truth Data on the Anatomy and Economics of Bulletproof Hosting, to be presented in the Usenix conference on 2019-08-15]

www.wired.com/story/medtronic-insulin-pump-hack-app/ TWO YEARS AGO, researchers Billy Rios and Jonathan Butts discovered disturbing vulnerabilities in Medtronic’s popular MiniMed and MiniMed Paradigm insulin pump lines. An attacker could remotely target these pumps to withhold insulin from patients, or to trigger a potentially lethal overdose. And yet months of negotiations with Medtronic and regulators to implement a fix proved fruitless. So the researchers resorted to drastic measures. They built an And. The FDA’s Schwartz says, though, that while the relevant models of MiniMed pump are not widely used in the US anymore, they have “a lot of usage worldwide.” Part of the reason it took time to announce the voluntary recall, she says, was the difficulty of coordinating with regulatory agencies around the world to coordinate the voluntary recall on an international level.

Topinambour & Windows event logs

www.cert.at/services/blog/20190716140317-2501_en.html “Now let me raise a question: “Is it normal for a standard user to run ‘cmd.exe /c net use \\$IP-ADDRESS\…’?” I would say it’s not and therefore seeing this in an event log can be considered an investigative hint, or can be an event triggering an investigation in a SOC team.. ” I’m not saying building up a centralized monitoring of Windows client event logs including relevant events is easy or that using event logs is the only way for detection. What I’m saying is: if you don’t do it, you are missing a lot of incredibly useful information for SOC teams as well as client administrators.
