The Usual Suspects
Leading the charge was LockBit, a notorious ransomware gang that hit hard, racking up a hefty share of attacks. But even the big dogs stumble—law enforcement swooped in later in the year, clipping their wings and slowing them down. Enter RansomHub, the new kid on the block, picking up speed with a steady climb in heists that kept companies on edge. And then there were the others—Play, Qilin, Akira, and Black Basta—each leaving their mark like a rogues’ gallery of cyber villains.
- LockBit: A prominent ransomware collective responsible for a significant portion of extortion attacks. However, its activity reduced later in the year due to law enforcement actions.
- RansomHub: Emerged as a significant threat, showing a consistent upward trajectory in attacks.
- Other Operations: Included Play, Qilin, Akira, and Black Basta.
The Weak Spots
How did they get in? Picture a fortress with rusty gates: attackers slipped through vulnerabilities in network appliances, exploited unpatched software, and poked at misconfigured systems like they were picking locks. Widely used tech had its weak points exposed, and without strong defenses—like multi-factor authentication (MFA) for cloud services—companies were sitting ducks.
- Exploitation of vulnerabilities in network appliances, unpatched software, misconfigured systems, and weaknesses in widely used technologies served as entry points for ransomware deployment.
- Lack of robust authentication and access controls, particularly the lack of multi-factor authentication (MFA) for cloud services, also contributed to successful ransomware attacks.
The Masterminds
Behind the chaos were financially motivated cybercrime crews, working with slick affiliates to pull off these capers. They often teamed up with Initial Access Brokers (IABs), shadowy figures who’d sneak into networks first and hand over the keys. Even some nation-state actors got in on the game, blurring the lines between crime and espionage.
- Financially motivated cybercrime groups and their affiliates are the primary threat actors behind ransomware attacks.
- Initial Access Brokers (IABs) often provide access to victim networks that ransomware actors then exploit.
- Some nation-state actors have also been linked to ransomware activities.
The Break-In
The crooks had a bag of tricks: zero-day flaws in edge devices were like secret trapdoors, while known software bugs and abused remote access tools were their crowbars. Phishing emails? Those were the baited hooks, reeling in victims to kick off the whole operation.

9. Insider Threats: The Betrayal Within
The Hidden Enemy
Picture 2024 as a year where the biggest dangers didn’t come knocking—they were already inside the house. Insider threats turned trusted employees and contractors into ticking time bombs, whether they meant harm or not. With legit access to systems and data, these folks held the power to unravel an organization from the inside out, making every handshake a potential risk.
- Insider threats, whether malicious or unintentional, remained a concern in 2024.
- Individuals with legitimate access to an organization’s systems and data can pose a significant risk.
The Rogue Players
The culprits were a mixed bag. The FAMOUS CHOLLIMA group had sneaky insiders sniffing around multiple sectors, hunting opportunities like corporate moles. Some operatives pulled a bolder con—grabbing software dev jobs with stolen or fake IDs, then either siphoning off data or just cashing paychecks like cyber freeloaders. And then there were the regular Joes—employees with IT access—who caught the eye of outside crooks looking for a puppet to pull strings.
- FAMOUS CHOLLIMA Group: Malicious insiders opportunistically seeking access across multiple sectors.
- Fraudulent Operatives: Using stolen or fake identities to land software development jobs, then exfiltrating data or simply collecting salaries.
- Targeted Employees: Potential for those with IT environment access to be targeted by external threat actors.
The Open Doors
How’d this happen? Legit credentials were the golden ticket—employees and contractors could swipe data, crash systems, or hand the keys to outsiders without breaking a sweat. Shaky access controls, zero monitoring of what folks were up to, and skimpy background checks left the vault wide open for anyone with a grudge or a greedy streak.
- Organizations are vulnerable due to the legitimate access granted to employees, contractors, and other trusted individuals, which can be abused to steal data, disrupt systems, or facilitate external attacks.
- Lack of proper access controls, insufficient monitoring of employee activity, and inadequate background checks increase this vulnerability.
The Puppet Masters
Malicious insiders—think disgruntled workers or ex-staff—were the obvious villains, striking from within. But external hackers got crafty too, either hijacking insider accounts or sweet-talking recruits into doing their dirty work. FAMOUS CHOLLIMA stood out, playing insiders like chess pieces for cash or chaos, depending on the day.
- Malicious employees, contractors, or former employees can intentionally cause harm.
- External threat actors may compromise insider accounts or recruit insiders to gain access.
- The FAMOUS CHOLLIMA group demonstrates a focus on leveraging insiders for various motivations.
The Inside Job
The tricks were straight out of a spy flick. Insiders used their own logins to sneak into sensitive systems, pilfering data or planting malware like digital landmines. Some even built backdoors for later. Outside actors leaned on social engineering—phishing or smooth-talking—to turn insiders into unwilling accomplices, handing over access or flipping the switch on mayhem.
- Insiders can use their legitimate credentials to access sensitive data and systems for unauthorized purposes.
- They may intentionally introduce malware or create backdoors.
- Social engineering can be used by external actors to manipulate insiders into granting access or performing malicious actions.
The Fallout

In some cases, these operatives snagged code or intellectual property, walking off with the company jewels. It was a slow burn of betrayal, proving the enemy within could hit just as hard as any outsider.
- CrowdStrike observed FAMOUS CHOLLIMA’s malicious insiders opportunistically pursuing insider access across multiple sectors, potentially driven by salary rather than specific targeting.
- In some cases, FAMOUS CHOLLIMA operatives were observed exfiltrating code or intellectual property.
10. Phishing and Social Engineering: The Trust Trap
The Human Hook
Picture 2024 as the year cybercriminals turned people into their secret weapon. Security’s strongest link—us humans—was also its weakest, tripping over scams, clicking the wrong links, or just zoning out on best practices. Social engineering, with phishing as its star player, snuck into nearly every email threat, proving that exploiting trust was the fastest way past the gates. A whopping 71% of working adults fessed up to risky moves that left them wide open, and attackers knew it—playing on negligence, curiosity, or even a rare spiteful streak. Phishing held its crown as the top break-in trick for the second year running, now turbocharged by generative AI that made every lure slicker than ever.
