Finance & Security in Crypto: Protect Your Assets from Hackers and Scams

When you invest in cryptocurrency, you're not just buying coins—you're entering a world where Finance & Security, the system that keeps digital assets safe and transactions trustworthy. Also known as crypto safety, it's what stops thieves from draining your wallet and ensures your money stays yours. Unlike banks, there’s no customer service line to call if something goes wrong. If your keys are stolen, your crypto is gone. That’s why understanding Finance & Security isn’t optional—it’s survival.

One major threat? State-backed hacking. In 2025, North Korean cyber units stole over $2.1 billion in crypto by posing as IT contractors and slipping malware into crypto firms’ systems. The U.S. Treasury responded with OFAC sanctions, a powerful financial tool that freezes assets and blocks transactions tied to illegal actors. These sanctions hit not just wallets, but companies and individuals helping the hackers. It’s the first time a government has used financial pressure this aggressively against crypto theft—and it’s changing how everyone thinks about cryptocurrency theft, the act of stealing digital assets through hacking, phishing, or insider fraud.

Security isn’t just about government action. It’s about your habits. Are you using a hardware wallet? Do you know how to spot a fake airdrop? Is your exchange insured? These aren’t tech questions—they’re money questions. The same hackers who hit North Korea’s targets are now going after small investors with simple scams: fake apps, rigged giveaways, and phishing links that look real. You don’t need to be a coder to stay safe. You just need to know what to look for.

What you’ll find below isn’t theory. It’s real cases, real tools, and real steps people took to protect themselves. From how OFAC’s moves affect your exchange choices to how to check if a token is legit before you buy—this collection gives you the facts without the fluff. No jargon. No hype. Just what works.
