Think cybercrime is something that only happens to big corporations? Well, think again. Hackers don’t care whether you run a multinational company or manage a small online business. If there’s money, data, or even an opportunity to cause disruption, they’ll take it. The scariest part is that many of the most prominent hacking groups aren’t just random criminals; they’re highly organized, well-funded, and sometimes even backed by governments.
Some of these groups work silently, spying for years before making a move. Others operate like smash-and-grab gangs, stealing millions in minutes. A few do both. Understanding who they are and how they work isn’t just interesting; it’s necessary.

Lazarus Group
Lazarus Group is North Korea’s elite hacking team, and they’re all about money. Unlike groups focused on espionage, Lazarus funds a heavily sanctioned government. Their targets are usually banks, crypto platforms, and even entertainment companies.
In 2014, they hacked Sony Pictures, wiping data and leaking internal emails—a retaliation for The Interview, a movie mocking Kim Jong Un. But their biggest heist was the 2016 Bangladesh Bank hack. They tried to steal $1 billion but were stopped at $81 million.
Canada has also been a target of the Lazarus Group, North Korea’s notorious hacking unit. In 2017, WannaCry ransomware crippled the University of Montreal’s systems. Then, in 2022, they exploited the Log4Shell vulnerability to penetrate Canada’s energy infrastructure.
In the gaming industry, Stake.com lost about $41 million in crypto after its casino site was hacked. The attack bypassed multiple security layers before transferring Bitcoin and Ethereum to untraceable wallets.
Casino sites have introduced stricter verification protocols and enhanced encryption to boost their security and protect players. Online casinos in Canada, which are popular and have a large customer base, have added security measures to their operations to ensure players enjoy games in a safe environment. Seeing that other sectors have been hacked before in the country, the casino gaming industry can easily become a target.
REvil
REvil (short for “Ransomware Evil”) wasn’t about politics but about cash. They didn’t care who they hit as long as the ransom was hefty enough. Their biggest victim, JBS, the world’s largest meat processor, paid $11 million to regain its systems in 2021. Then there was Kaseya, an IT firm that got hit so hard thousands of businesses suffered. REvil demanded $70 million.
What made REvil different? They ran ransomware like a using a ransomware-as-a-service (RaaS) approach. Instead of hacking everything, they sold ransomware tools to other criminals. These affiliates broke into networks, deployed REvil’s software, and then split the profits.
They also pioneered “double extortion.” Instead of just locking up a company’s files, they stole copies first. That way, even if a company had backups, REvil could threaten to leak sensitive data.
Law enforcement cracked down on it, arrested members, and disrupted their networks. But the damage was done, and their tactics live on. If REvil proved anything, it’s that cybersecurity isn’t just about stopping hacks—it’s about preparing for when, not if, they happen.
Anonymous
Anonymous isn’t like other hacking syndicates. It has no leaders or organization, just a network of hackers striking whenever they feel like it. They’re digital vigilantes, going after corporations, governments, and institutions they see as corrupt.
Their methods include DDoS attacks (flooding sites until they crash), leaking documents, and defacing websites. In the 2000s, they targeted the Church of Scientology. Later, they attacked PayPal and Visa when they blocked WikiLeaks donations.
In 2022, when Russia invaded Ukraine, Anonymous declared “cyber war” on Russia. Suddenly, Russian government websites were offline, state media was getting hacked, and data was leaking.
Because Anonymous is so decentralized, predicting its next move is impossible. Anyone can claim to be Anonymous. They don’t always win, but they always make noise.
APT41 (Wicked Panda)
APT41, or Wicked Panda, is involved in both espionage and cybercrime. Linked to China, it hacks for political and financial gain. Most of its activities revolve around infiltrating foreign governments, stealing trade secrets in industries like tech, healthcare, and telecom, and hacking video game companies and financial institutions. They have also been linked to ransomware scams.
They use advanced tools to exploit software vulnerabilities before anyone knows they exist, making their attacks nearly impossible to stop in time. The U.S. indicted multiple APT41 members, but they’re still active. Their mix of espionage and crime proves how blurred the lines are in cyber warfare.
APT29 (Cozy Bear)
APT29, better known as Cozy Bear, is linked to Russian intelligence, likely the SVR. They’re not after cash but information. They’re spies, not thieves. Their biggest hit was the 2016 Democratic National Committee (DNC) hack.
They slipped into the system, grabbed thousands of emails, and leaked them, fueling U.S. political chaos. In 2020, they were accused of hacking COVID-19 vaccine research and trying to steal medical secrets.
What makes them dangerous is that they don’t just hack and run. They send phishing emails that look real. Once inside, they stay for months, sometimes years, watching and collecting data. Even if caught and kicked out, they adjust and try again.
Cozy Bear always adapts, no matter how much companies and governments upgrade security. The only real defense against them is training employees to spot phishing emails, locking down sensitive data, and using multi-layered security.
