New web targets for the discerning hacker
We kick off this month’s bug bounty roundup with some dramatic payout news – a record $2 million paid by blockchain technology company Polygon for a ‘double spend’ smart contract vulnerability.
The flaw, discovered by ethical hacker Gerhard Wagner, would have enabled an attacker to double the amount of cryptocurrency they intend to withdraw up to 233 times. In this way, a deposit of just $4,500 could have allowed a hacker to withdraw $1 million.
“The opportunities in crypto as a hacker are tremendous,” says Wagner. “I predict we will see high, single-digit, million dollar bounties announced from projects and white hats claiming them in a not-too-distant future.”
Meanwhile, a newly launched bug bounty platform in India is encouraging cybersecurity professionals and enthusiasts to sign up, and is promising free training and access to exclusive programs for its top 100 ethical hackers.
Cyber3ra, based in Nagpur, says the top three will also receive exclusive merchandising and early access to programs.
Researchers ‘s1r1us’ and ‘BlackFan’ have documented prototype pollution vulnerabilities found in more than 1,000 popular websites and 18 widely used JavaScript libraries, including Apple.com, Jira Service Management, HubSpot Analytics, and Segment Analytics.
The researchers believe that prototype pollution is being neglected: “We hope our blog gives more light to this attack surface and helps people mitigate these issues at scale,” they said.
And finally, we caught up with YouTube educator and security expert Katie Paxton-Fear during a Q&A session we held on Twitter for our readers.
She advises those at the start of their careers to play the field a little: “I think my biggest advice is not to get attached to one field right away, spend some time figuring out what about security really sparks joy for you,” she says.
Katie recommends IDORs as a good area of focus for newbies: they’re one of the most common bugs, she says, and can be ‘high’ or ‘critical’ in severity.
“[The] best way to find them is to sign up with two accounts and see if you can do actions to account A while using the cookies of account B,” she says.
