New web targets for the discerning hacker

Bug Bounty Radar - The latest bug bounty programs for April 2022

With all eyes on Ukraine this month, HackerOne has been forced to apologize after bug bounty hunters in the country were temporarily locked out of their accounts, preventing access to their funds.

Chief hacking officer and CISO Chris Evans blamed the problem on delays in backend payment systems. The problem occurred following sanctions in the region, with HackerOne first suggesting that payments to bug bounty hunters in Russia and Belarus would be automatically donated to charity. It later backtracked, saying the money would be held in their accounts.

Meanwhile, concerns have been raised over a plan by Estonia-based bug bounty platform HackenProof to unearth critical vulnerabilities in the digital infrastructure of both the Ukrainian and Russian governments, with the aim of bolstering Ukraine’s defenses. Hackers said they were concerned that the plan could potentially escalate the conflict.

In other news, Password manager 1Password has upped its maximum bug bounty reward to $1 million – one of the biggest potential payouts in the industry. It says logic issues are likely to net the biggest rewards, and that one researcher has managed to claim nearly half of the total payouts to date by looking for issues such as this.

There was a second bite of the cherry this month for security researcher Youssef Sammouda – last year, he netted $126,000 for discovering three flaws in Facebook’s Canvas technology, used for embedding online games and interactive apps in its platform. Sammouda has now won an extra $98,000 for revealing problems with Facebook’s initial attempt at a fix.

And finally, Chromium developers have patched an inappropriate implementation in HTML parser which was discovered by Michał Bentkowski, a penetration tester for Polish cybersecurity firm Securitum. The medium-severity bug meant that websites thought to be XSS-protected could have been unintentionally exposed to XSS attacks in Chrome sessions.
