Last Tuesday, aerospace and energy equipment manufacturer Honeywell, a Fortune 100 firm, declared they noticed a malware intrusion that disrupted a limited number of its information technology systems.

The ongoing investigation into the Honeywell cyberattack shows there is no evidence that the hacker accomplished to withdraw data from systems that store customer information. Nevertheless, based on its statement, it cannot completely rule out that some customer data may have been compromised.

Industrial giant Honeywell, which reported some $33 billion in sales last year, published an announcement on March 23, 2021, saying:

At this time, we do not expect this incident will have a material impact on Honeywell. We promptly took steps to address the incident, including partnering with Microsoft to assess and remediate the situation. Our systems have since been secured, we identified the point of entry, and all unauthorized access has been revoked.


The company announced the malware attack was detected “recently” and only a “limited number” of IT systems were disrupted. We don’t know yet if ransomware was involved or who was responsible.

Law enforcement has been informed and affected services are working properly at the moment, according to Honeywell.

The news about Honeywell comes shortly after Canada-based IoT company Sierra Wireless disclosed that some of its internal IT systems were recently hit by ransomware. Sierra, which also provides solutions for industrial organizations, said the incident forced it to suspend production at its manufacturing sites.

Other big organizations that recently announced disruption to production operations due to a cyberattack are Molson Coors, a multinational drink and brewing company, and WestRock, a corrugated packaging company.
