While it is certainly a valid exercise to benchmark a cybersecurity program against a framework, such as NIST, these paper-work efforts articulate the To truly test the effectiveness of an organization's detect and response capabilities to a cyberattack, it's necessary to provide a sparring partner.This session will discuss the process of cycling the SOC and IR team through a realistic adversary simulation (from a prepared red team), and then observing the organization's response, from the eyes of an experienced blue team.This general technique can also adapt to various code contexts and lead to protocol smuggling and SSRF bypassing.Several scenarios will be demonstrated to illustrate how URL parsers can be exploited to bypass SSRF protection and achieve RCE (Remote Code Execution), which is the case in our Git Hub Enterprise demo.These attacks can randomly choose victims or target a given victim.We verified these attacks with our own phones in operators' network in a small controllable scale.The experiments proved the vulnerability really exists.Finally, the countermeasures are proposed and now we are collaborating with operators and terminal manufactures to fix this vulnerability.
In this presentation, one vulnerability in CSFB (Circuit Switched Fallback) in 4G LTE network is introduced.Understanding the basics of this technique, the audience won't be surprised to know that more than 20 vulnerabilities have been found in famous programming languages and web applications aforementioned via this technique.For years, the cybersecurity industry has struggled with how to measure the cyber-readiness of an organization.Since the first Black Hat conference 20 years ago, the security community, industry and the world have changed to the point that it's time to re-examine whether we're living up to our responsibilities and potential.
Long gone are the days when "hacking" conjured up a sense of mischief and light-heartedness, with limited risks and harm.
We named this attack as 'Ghost Telephonist.' Several exploitations can be made based on this vulnerability.
