Summary
SeriousNND (also known as NND or NoNameDiamond) is a highly active but widely discredited threat actor, self-proclaimed data broker, and conman operating within Telegram-based cybercrime and OSINT communities. Despite a grandiose bio claiming to be an “Ex CIA Cyber Security Officer & IT Engineer” and the CEO of “Umbrella Security,” chat logs reveal a consistent pattern of extreme LARPing (Live Action Role-Playing), serial fabrications, and fundamental technical incompetence.
He is primarily known for attempting to sell exorbitant, subscription-based access to “Umbrella Cloud”—a purported 669TB database of breached data—while simultaneously advertising absurd and fictitious services such as “DNA Editing,” “Aimbot Drones,” and “Directed Energy Weapons.” Due to his frequent spamming, scam accusations, and inability to demonstrate basic IT skills, he is regularly mocked and banned by administrators in prominent Telegram groups.

Notes
- Technical Incompetence: Despite his bio asserting he is an elite 14+ year veteran hacker and ex-CIA officer, logs repeatedly show him asking for basic IT help. He is observed asking how to search within `.7z` files, begging for help with database indexing, asking others to provide an NTLite serial key, and failing to understand the difference between standard hash algorithms.
- Geographic Origin vs. Claims: He claims to operate on “Washington-DC Timezone EDT.” However, logs from 2020 and 2022 show him speaking fluent Serbian/Croatian and deeply understanding Balkan cultural nuances. Peers frequently identify him as a “Balkan/Slav” actor pretending to be American.
- Grandiose Fabrications: SeriousNND routinely claims to possess impossible, sci-fi technologies. Among his documented claims: inventing a proprietary compression algorithm that shrinks files by “71 times” with zero data loss, possessing the unreleased source code and weights to Grok 4 and GPT-5, and having methods to read human brainwaves via 4G/5G cell towers.
- Scam Tactics & Hypocrisy: He uses high-pressure sales tactics for his “Umbrella Cloud,” asking for up to €9,000 in Monero/USDT for “VIP” access. Ironically, while claiming to generate millions of dollars and possessing elite hardware, he is frequently seen begging community members to donate spare SSDs and hard drives to him because he “struggles to afford 4 ssd's.”
