In this paper we examine how, even when faced with this statistical improbability, ISE discovered 732 private keys as well as their corresponding public keys that committed 49,060 transactions to the Ethereum blockchain. Additionally, we identified 13,319 Ethereum that was transferred to either invalid destination addresses, or wallets derived from weak keys that at the height of the Ethereum market had a combined total value of $18,899,969. In the process, we discovered that funds from these weak-key addresses are being pilfered and sent to a destination address belonging to an individual or group that is running active campaigns to compromise/gather private keys and obtain these funds. On January 13, 2018, this “blockchainbandit” held a balance of 37,926 ETH valued at $54,343,407.
Password managers allow the storage and retrieval of sensitive information from an encrypted database. Users rely on them to provide better security guarantees against trivial exfiltration than alternative ways of storing passwords, such as an unsecured flat text file. In this paper we propose security guarantees password managers should offer and examine the underlying workings of five popular password managers targeting the Windows 10 platform: 1Password 7 , 1Password 4 , Dashlane , KeePass , and LastPass . We anticipated that password managers would employ basic security best practices, such as scrubbing secrets from memory when they are not in use and sanitization of memory once a password manager was logged out and placed into a locked state. However, we found that in all password managers we examined, trivial secrets extraction was possible from a locked password manager, including the master password in some cases, exposing up to 60 million users that use the password managers in this study to secrets retrieval from an assumed secure locked state.
The research results from our assessment of 12 healthcare facilities, 2 healthcare data facilities, 2 active medical devices from one manufacturer, and 2 web applications that remote adversaries can easily deploy attacks that target and compromise patient health. We demonstrated that a variety of deadly remote attacks were possible within these facilities, of which four attack scenarios are presented in this report. To understand these ecosystems, a two year study was performed from January, 2014 through January, 2016 of critical elements within these facilities as they relate to securing patient health. Our goal was to create a blueprint --a step-by-step action plan-- that all medical facilities can follow as the foundational element in reaching full security readiness. The research was driven by a handson analysis of various healthcare systems, applications, and budgets, interviews with hospital, data center, and medical device manufacturer employees, and sourcing industry knowledge from thought leaders on our advisory board. The findings show an industry in turmoil: lack of executive support, insufficient talent, improper implementations of technology, outdated understanding of adversaries, lack of leadership, and a misguided reliance upon compliance. These findings illustrate our greatest fear: patient health remains extremely vulnerable. The output of the research is the production of a modern patient-health focused attack model, and a blueprint that advocates a phased approach to security design and implementation for healthcare facilities that focuses on the protection of patient health assets.

ISE security analysts considered the increasing prevalence of SSL inspection on corporate networks, threats to the certificate authority model that could allow SSL inspection to spread to other types of networks in the future, and how built-in browser key generation capabilities could be leveraged to achieve mutual authentication and greatly frustrate, if not prevent, mass-scale, automated SSL inspection.
ISE identified 21 (70% of sites tested) financial, healthcare, insurance and utility account sites that failed to forbid browsers from storing cached content on disk, and as a result, after visiting these sites, unencrypted sensitive content is left behind on end-users' machines.
ISE researchers discovered critical security vulnerabilities in numerous small office/home office (SOHO) routers and wireless access points. These vulnerabilities allow a remote attacker to take full control of the router's configuration settings; some allow a local attacker to bypass authentication directly and take control. This control allows an attacker to intercept and modify network traffic as it enters and leaves the network.
