Risky Business returns for 2026! Patrick Gray and Adam Boileau talk through the week’s cybersecurity news, including:

• Santa brings hackers MongoDB memory leaks for Christmas
• Vercel pays out a million bucks to improve its React2Shell WAF defences
• 39C3 delivers; the pink Power Ranger deletes nazis, while a catgirl ruins GnuPG
• Cambodian scam compound kingpin gets extradited to China, and we don’t think it’ll go well for him
