If cyber defenses are stronger than ever, why are attackers still stealing hundreds of millions of dollars?
That is the question many business leaders are asking after new reporting revealed that North Korea linked cybercriminals are now responsible for roughly 76% of all cryptocurrency stolen in 2026 so far. According to a recent report from <a href="https://www.darkreading.com/cybersecurity-analytics/crypto-stolen-2026-north-korea?shem=dsdf,sharefoc,agadiscoversdl,,sh/x/discover/m1/4">Dark Reading</a>, the attacks are becoming larger, more targeted, and increasingly difficult to stop before damage occurs.
While these attacks are focused on cryptocurrency platforms and decentralized finance systems, the lessons apply to every business. The same attack methods being used against crypto organizations are also being used against manufacturers, healthcare providers, law firms, financial firms, and small businesses every day.
The real story is not just about stolen cryptocurrency. It is about how modern attackers are bypassing traditional security models faster than organizations can respond.
So what exactly happened?
According to the Dark Reading report, North Korean threat actors stole an estimated $577 million during the first four months of 2026. Two attacks alone accounted for most of the losses:
- A $285 million attack against Drift Protocol
- A $292 million attack against KelpDAO
Researchers from <a href="https://www.theblock.co/post/399569/north-korea-accounts-for-76-of-2026-crypto-hack-losses-with-theft-since-2017-topping-6-billion-trm-labs">TRM Labs</a> found that North Korea linked groups are increasingly focused on fewer attacks with much larger payouts.
The attacks were not simple smash and grab operations. They involved advanced reconnaissance, social engineering, credential abuse, and deep understanding of the targeted environments.
The report also noted growing concerns that artificial intelligence may be helping attackers improve phishing campaigns, automate reconnaissance, and accelerate exploit development.
This is an important shift for businesses to understand. Attackers are no longer relying solely on noisy malware that triggers alerts immediately. They are using patience, deception, and legitimate tools to quietly move through environments before launching the final attack.
Why are attackers getting past security tools?
Many organizations still rely heavily on a “Detect and Respond” cybersecurity strategy.
That model assumes attackers will eventually get inside systems and that security teams will detect malicious activity quickly enough to stop the attack before serious damage occurs.
The problem is that attackers are moving faster than ever.
According to the <a href="https://www.verizon.com/business/resources/reports/dbir/">2026 Verizon Data Breach Investigations Report</a>, 31% of breaches now begin with vulnerability exploitation, surpassing stolen credentials for the first time. The report also warns that AI is shrinking attack timelines from months to hours.
At the same time, many attacks avoid traditional detection entirely by using:
- Legitimate administrator tools
- Stolen credentials
- Trusted applications
- Script-based attacks
- Living off the land techniques
- Security tool tampering
Modern ransomware and financially motivated attacks can move from initial access to widespread compromise in a matter of hours.
By the time alerts appear, the damage may already be underway.
What does this mean for businesses outside crypto?
Many executives assume these attacks only affect cryptocurrency firms or large enterprises.
That assumption is dangerous.
The tactics used in these attacks are now common across industries. Attackers target the easiest path into an organization, which often includes:
- Third-party vendors
- Remote access tools
- Employee credentials
- Weak endpoint controls
- Unrestricted application execution
- Unpatched systems
According to IBM related breach research, the average global data breach cost is now approximately $4.44 million, while U.S. organizations face average costs exceeding $10 million.
Those costs extend far beyond ransom payments or stolen funds. Businesses often experience:
- Operational downtime
- Lost productivity
- Regulatory investigations
- Reputation damage
- Customer distrust
- Legal exposure
- Incident recovery costs
- Cyber insurance complications
For many organizations, the business interruption itself becomes more damaging than the initial breach.
Could this happen even if we already have EDR?
Yes.
Endpoint Detection and Response tools remain valuable, but attackers increasingly know how to bypass or disable them.
That is especially true in attacks involving:
- Stolen administrator credentials
- PowerShell abuse
- Trusted applications
- Script-based execution
- AI enhanced phishing
- Remote management tools
North Korean linked attacks have repeatedly demonstrated that sophisticated threat actors understand how security teams operate and how traditional tools respond.
This is one reason many cybersecurity experts are shifting focus from detection alone toward prevention and containment.
Why are traditional defenses struggling?
Traditional cybersecurity strategies were built around the assumption that organizations could identify malicious behavior early enough to stop attackers before widespread compromise occurred.
But several realities have changed:
- Attackers automate reconnaissance
- AI accelerates phishing and exploit development
- Malware mutates rapidly
- Credentials are constantly stolen
- Remote work expanded attack surfaces
- Third-party risks continue to grow
The Verizon DBIR also reported that third-party supply chain breaches increased significantly and that mobile social engineering attacks are becoming more successful than traditional phishing.
The speed of modern attacks is exposing the limitations of response-based security models.
Organizations need security controls capable of preventing unauthorized actions before attackers gain momentum.
What is changing in endpoint security?
More organizations are recognizing that prevention must play a larger role in cybersecurity strategy.
That is where “Isolation and Containment” becomes important.
Rather than assuming malicious code will execute and then attempting to detect it afterward, Isolation and Containment focuses on preventing unauthorized activity from running in the first place.
This approach helps organizations:
- Restrict unauthorized applications
- Prevent malicious scripts from executing
- Limit lateral movement
- Reduce attacker access
- Shrink blast radius
- Stop encryption before ransomware spreads
- Contain compromise before operational disruption escalates
This is why many businesses are reevaluating prevention-first approaches alongside traditional detection technologies.
Solutions like AppGuard are increasingly part of those conversations because they focus on preventing attacks through Isolation and Containment rather than relying solely on detecting malicious behavior after execution. AppGuard is a proven endpoint protection solution with a 10-year track record focused on prevention through Isolation and Containment.
What Should Businesses Do Next?
Business leaders should assume that some attacks will bypass traditional detection tools.
That does not mean organizations are powerless. It means cybersecurity strategies must evolve.
Organizations should consider taking the following steps:
- Assume detection will eventually fail
- Add prevention-focused security layers
- Reduce unnecessary endpoint execution freedom
- Limit administrative privileges
- Segment critical systems and sensitive data
- Review third-party and vendor access
- Test incident response and business continuity plans
- Simulate ransomware and credential compromise scenarios
- Strengthen endpoint containment policies
- Focus on reducing attacker movement inside environments
Cybersecurity is no longer just about identifying threats. It is about preventing attackers from gaining the freedom to operate once they get inside.
The organizations that adapt fastest to this reality will be better positioned to reduce operational risk and business disruption.
Business owners who want to better understand how prevention-first security can stop attacks before damage occurs should talk with CHIPS about how AppGuard can help prevent incidents like this through Isolation and Containment.
