CYBERBRIEFING | April 21, 2026
Welcome to Cyber Briefing, your daily source for all things cybersecurity. We bring you the latest advisories, alerts, incidents, and news every weekday.
Today’s edition highlights a surge in sophisticated cyber threats and high-stakes breaches, notably the PureRAT malware campaign using steganography to hide payloads in images and the $290 million Kelp DAO crypto heist. Major organizational risks are also detailed, including the Gentlemen ransomware targeting hypervisors and a significant API flaw in the Lovable AI builder that exposed source code and credentials.
On the corporate and regulatory front, the landscape is shifting with ServiceNow’s $7.75 billion acquisition of Armis to bolster asset security and Poste Italiane’s €12.5 million fine for data privacy violations. Additionally, new compliance measures like PlayStation’s age-gating in the UK and offers professional growth opportunities through medical device cybersecurity summits and free youth AI camps.
