Hacking, AppSec, and Bug Bounty newsletter
2017-05-15 | WannaCry, Twitter IDOR, and cyber insurance lawsuits
Monday, May 15
Welcome to CyberAttack Monday (may the rest of your week be better than today)!
Holy ransomware batman: WannaCry targets span the globe: NHS hospitals across England hit by large-scale cyber-attack and an accidental hero but new variants detected. This is a plot that reads like a bad cyber spy novel. Good news though, Microsoft has guidance for the WannayCrypt attacks (update your ish). And don’t say we didn’t warn you this could happen.
Arbitrary Local-File Read from Admin - Restore From Backup due to Symlinks [29 upvotes] - $512 bounty for this report to Discourse by @Ziot. Manually modifying the tar archive and adding a symlink, you are able to read any arbitrary file that the user has permission to.
[IDOR][translate.twitter.com] Opportunity to change any comment at the forum [27 upvotes] - $1,120 bounty for this report to Twitter by @kedrisch. Reported, fixed, and bountied 6 months ago but publicly disclosed over the weekend (playbook for other co’s looking to leverage benefit of public disclosure - statutory period of 6-months? Just a thought).
You can see all the latest and greatest disclosures and bounties on www.hackerone.com/hacktivity.
