Leaks of user credentials can have long-term consequences. Cybercriminals often rely on online hacking forums to purchase such leaked credentials for use in their attacks. In the last 24 hours, the instances of Deliveroo account hacks are tell-tale signs of how attackers abuse these stolen credentials for financial gains and other motives. On the other hand, data breaches continue to torment organizations and individuals alike. Personal information of thousands of Tennessee students was compromised after a database operated by a third-party vendor, Graduation Alliance, suffered a breach. 

Meanwhile, the Chinese threat actor group APT 15 has been found using a previously undocumented backdoor called Okrum. The backdoor is used to inject the Ketrican malware and has the ability to download/upload files, execute binaries, run shell commands, update itself, and more.

The Palo Alto GlobalProtect Gateway products were found to be affected by a critical remote code execution vulnerability. The vulnerability can be exploited by sending a specially crafted request to a vulnerable SSL VPN.
