New web targets for the discerning hacker
The otherwise typically low-key month of August also brings infosec’s most renowned conference: Black Hat USA, which this year brought a word of warning for bug bounty hunters.
Dylan Ayrey, CEO of Truffle Security, cited a number of cases in which poor research and shoddy data governance has led to the leak of users’ personally identifiable information. In some cases, the data is still available long after the corresponding ticket has been closed, he warned.
“These privacy leaks in bug bounties are really common, and for every example that we can share publicly there are 100 examples that can’t be shared publicly,” said Ayrey.
In another, alleged example of suboptimal bug bounty practices CrowdStrike came under fire recently over its vulnerability disclosure process.
Pascal Zenker, a partner of Swiss security analyst service Modzero AG, claimed the Texas-based cybersecurity firm’s bug bounty program, run through HackerOne, is “NDA-ridden”, while the disclosure process “turned unprofessional in the end”.
CrowdStrike, however, defended its actions and countered that Modzero had not responded to attempts to “continue the dialogue” until six weeks had elapsed.
Among the most notable new bug bounty programs this month is Google’s latest VRP, this time focused on its open source projects, such as Golang, Angular, and Fuchsia.
Announced on August 30, the Open Source Software Vulnerability Rewards Program (OSS VRP) is designed to stem the rising tide of attacks against the software supply chain.
There were several notable payouts on existing Google VRPs, most notably when Alesandro Ortiz netted $20,000 from the tech giant – giving $4,000 to a collaborator – for unearthing a bug in the Chromium project. This allowed attackers to bypass site isolation protection through iFrames and popup windows to steal private information, read and modify cookies, and gain access to microphone and camera feeds, among other exploits.
Meanwhile, researcher ‘NDevT’ discovered two XSS vulnerabilities in Google Cloud, DevSite, and Google Play that could lead to account hijacks. They won $3,000 and $5,000 in bug bounties for their pains.
And there was a $5,000 payout for a third Google issue, with Adi Cohen discovering an XSS in AMP for Email that involved tricking Gmail’s dynamic email feature into a rendering context that the browser would not use to render a given piece of code.
Finally, in non-Google payout news, there were $4,000 and $5,000 rewards respectively for serious GitHub Pages and Reddit issues, while a Yahoo hackathon paid out $218,121 for 218 bug submissions related to its text search engine tool Vespa.
