Recent Ransomware Attacks in 2024 (Updated October 2024)

After several notorious ransomware gangs were knocked out by law enforcement in 2023, ransomware attacks are on the rise again and soaring to all-time highs in 2024. Many gangs quickly reorganized and reformed, with leaders launching new platforms and expanding their web of bad actors. 

Ransomware attacks are bigger and bolder than ever this year, but even as attackers focus on new targets, small- and medium-sized enterprises (SMEs) remain under threat. With security breaches and ransom prices surging, it’s critical to stay on top of the latest attack tactics, gangs, and news. Let’s see who’s behind the most damaging ransomware attacks this year, and how you can protect your network, customers, and co-workers. 

Recent Ransomware Attacks In 2024

This year ransomware is on pace to cause over $40 billion in losses for organizations in the U.S. Ransoms, lost productivity, and system outages all factor in the equation. And large-scale breaches involving ransomware are not a phenomenon of 2024 at all. But even worse, people’s lives are increasingly put at risk by malicious attackers. These are some of the most alarming attacks of 2024.

September 2024

NHS London: Qilin ransom gang unleashed an attack that compromised the data of almost 1 million National Heathcare System patients in London hospitals. The attackers published personal information about patients with sensitive medical conditions like cancer and sexually transmitted diseases.

Stillwater Mining Company: In September, Stillwater company officials discovered the personal information of over 7,000 employees had been stolen using RansomHub RaaS (Ransomware as a Service). The attack first happened over the summer, but it took Stillwater months to catch on to the breach.

Kawasaki Motors Europe: RansomHub was also behind a major attack on Kawasaki’s European offices. Kawasaki swiftly shut its servers down to isolate the issue and perform recovery operations. RansomHub claims to have stolen almost 500 GB of data.

August 2024

City of Columbus, OH: Rhysida ransom group stole a massive 3TB of data from the City of Columbus, including sensitive employee records and data. After the city refused to meet Rhysida’s ransom price all the data was dumped onto the dark web.

Sumter County, FL Sheriff: Rhysida hit another government target, breaching the Sheriff’s Office systems and potentially compromising 150,000 citizens. Passports, SSNs, and other data was stolen. Rhysida demanded a payment of 7 bitcoin (worth almost half a million dollars).

Keytronic: Electronics manufacturing firm Keytronics reported losing over $17 million due to a ransomware attack by Black Basta, that disrupted production and office operations at its facilities in the U.S. and Mexico.

July 2024

Disney: NullBulge Group stole 1TB of data from Disney’s internal Slack platform and leaked it online. The breach included unreleased Disney projects, concepts, artwork, and code. The hackers asserted they were acting in the name of “artists’ rights.”

Schneider Energy: Cactus ransomware stole terabytes of company data in a breach. The attack compromised over 2,000 enterprise clients including Walmart, PepsiCo, Hilton, and DuPont. It’s unknown whether ransom demands were met. 

Notable Ransomware Groups

Even after coordinated federal and international crackdowns, ransomware gangs are as powerful as ever. Groups that were previously broken up emerged under new criminal organizations, and newer gangs rose to prominence in some of the highest-profile attacks of the year. These are a few of the most dangerous names in ransomware. 

LockBit is a Russian gang with global reach that roared back with a vengeance in 2024 after suffering a defeat when law enforcement took down its platform. LockBit provides RaaS (Ransomware as a Service) and has been the most deployed ransomware since 2022. Because of LockBit’s popularity, attacks can vary greatly in tactics and techniques.

ALPHV/BlackCat was formed after a gang known as BlackMatter’s servers were taken down by a sting in 2021. ALPHV makes some of the most technically advanced ransomware out there, capable of evading even the top cybersecurity systems. They’re thought to have the most experienced and tech savvy network of affiliates, and attack both Windows and Linux systems. ALPHV is one of the only ransom gangs to use a “triple extortion” technique leveraging stolen data, encryption, and denial of service attacks.

Rhysida is a fast-rising, aggressive ransomware gang responsible for some of the most damaging attacks in 2024. Rhysida’s malware was initially considered to be novice, but it rapidly became more elaborate and difficult to detect. Rhysida has led the offensive against healthcare systems and government offices.

Hunters International, ShinyHunters, 8Base, and BlackSuit are other established ransomware gangs that thrived in 2024. DragonForce and RansomHub are newer names emerging as more formidable threats this year.

Latest Ransomware Trends

Several ransomware trends took hold this year, with attackers focusing on bigger targets and demanding bigger payouts to match. Attacks on infrastructure became more common — attackers went hard after healthcare systems, government offices, and supply chain vendors.

Like everyone else, hackers increasingly deployed AI to help them carry out attacks. AI allows malware to adapt in real time to evade security, or can be used to clone voices, email, or other communications to make phishing seem more legit.

Ransomware as a Service continued to grow in popularity, as ransomware providers made their platforms more accessible to bad actors with fewer technical skills. Ransomware also got more sophisticated across the board, taking advantage of zero-day vulnerabilities more frequently and utilizing remote access tools to improve the effectiveness of attacks.

As always, phishing attacks on individual employees were one of the most effective ways for ransomware gangs to exploit systems. Attackers often breached security through individuals in BYOD situations or on SaaS cloud platforms with fewer safeguards.

With ransomware becoming more accessible and sophisticated, it’s predicted that attacks will only get more frequent — and more disruptive — as we head into 2025.

Ransomware Prevention and Protection

Ransomware can be tough to defend against because it can infiltrate an entire network through just one user. The more you can do to protect your users and network, the better chance you’ll have to successfully fend off bad actors.

Best Practices for Preventing Ransomware

These are some tried-and-true methods to help prevent a ransomware attack and keep your network running securely.

• Use Zero Trust security policies following a “trust nothing, verify everything” principle.

• Secure your network with unique passwords and multi-factor authentication (MFA).

• Keep security patches up to date on all software and services like email, servers, and VPNs.

• Back up data frequently, on multiple different media formats and keep one off-site copy.

• Educate users about device safety and how to recognize the latest phishing scams.

• Utilize AI to fight malware or other malicious threats.

Choosing the Right Security Solutions

The most effective security solutions vary from organization to organization. By taking the time to analyze the specifics around the way your company uses technology, you’ll gain the insights to develop a rock-solid defense strategy.

• Map attack surfaces and be aware of the latest ransomware attack vectors to identify vulnerabilities and determine best defenses.

• Evaluate security risks of SaaS or other third-party platforms your organization is using.

• Evaluate vulnerabilities unique to remote work and BYOD.

• Consider access controls like single sign-on (SSO), conditional access, password management, or passwordless authentication to improve individual user security.

• Unify IT stacks to reduce exploitable security gaps.

Recovery and Response Strategies

No matter how good your defenses are, sometimes ransomware sneaks into your system. By having a response plan ready to go, you can mitigate attacks quickly and stave off major damage.

• Create an incident response plan with standardized protocols for identifying and managing breaches.

• Isolate the infected system to prevent ransomware from spreading.

• Remove ransomware with antivirus and antimalware software, then clean the infected system.

• Restore data from a clean backup source. Refrain from using backups that were made while the system was under attack as they could contain encrypted files that could relaunch the attack.

• Review your security response and make improvements where vulnerabilities are detected.

• Explore insurance coverage against ransomware and other cyberattacks.

If considering a ransom payment, be aware that meeting attackers’ demands usually encourages future attacks.
