Being protected against ransomware has stopped being a question of antivirus and become a question of architecture and process. Ransomware is no longer a threat exclusive to large corporations. Today, any company—regardless of its size or sector—can fall victim to an attack that encrypts its files, paralyzes its operations, and demands a multi-million dollar ransom to regain access to its own information.
In Latin America, ransomware attacks have increased significantly in recent years, and Argentina is no exception. If your company handles sensitive data, operates internet-connected systems, or simply uses corporate email, you are vulnerable. The question isn’t if you will be attacked, but when and how prepared you will be .
What is ransomware and why is it so dangerous?
Ransomware is a type of malware that, once installed on a system, encrypts the files on the computer or the entire network, rendering them inaccessible. Attackers then demand payment—usually in cryptocurrency—in exchange for the decryption key.
What makes it especially dangerous is its ability to spread laterally through an organization’s internal network in a matter of minutes, affecting not just a single computer, but servers, databases, and entire critical systems.
5 characteristics of modern ransomware that every company should know
1. It is mainly distributed through phishing
Most ransomware attacks begin with a seemingly legitimate email. A malicious attachment, a link that redirects to a fake website, or an invoice from a “known supplier” can be the entry point. Employees are the first link, and also the most vulnerable.
2. Exploit unpatched vulnerabilities
Operating systems and applications with pending updates are prime targets. Attackers constantly monitor which known vulnerabilities haven’t been patched and exploit them automatically. Having outdated software on your network is essentially leaving the door ajar.
3. Operates silently before activating
Modern ransomware doesn’t act immediately. It can remain dormant on the network for days or weeks, mapping systems, escalating privileges, and exfiltrating data before executing the encryption. By the time the attack becomes visible, the damage is already done.
4. It also attacks backups
One of the most critical developments in modern ransomware is its ability to identify and delete or encrypt local backups before activating. Companies that rely solely on their internal backups discover, at the worst possible moment, that those backups have also been compromised.
5. It combines encryption with data extortion.
The “double extortion” model is becoming increasingly common: in addition to encrypting files, attackers steal them and threaten to publish them if the ransom is not paid. This makes the attack not only an operational problem, but also a reputational and regulatory compliance issue.
How to protect your company? Heimdal Security has the answer.
Given such a sophisticated threat landscape, traditional antivirus solutions are no longer sufficient. A layered security approach is needed, with real-time detection and response capabilities, vulnerability management, and DNS traffic control.
Heimdal Security is a Danish cybersecurity platform recognized worldwide for its proactive approach and unified architecture. Unlike conventional solutions, Heimdal doesn’t just detect known threats; it anticipates and neutralizes attacks before they can be executed.
What makes Heimdall different:
→ DNS Protection and Malicious Traffic Filtering: Heimdal intercepts network traffic at the DNS level, blocking communication with command and control servers used by ransomware. This stops the attack in its preparation phase, before encryption is activated.
→ Automatic Patch and Vulnerability Management. Its Patch & Asset Management module automates the updating of operating systems and over 120 third-party applications, eliminating vulnerabilities that attackers exploit. No manual intervention, no delays.
→ Endpoint Detection and Response (EDR) Heimdal monitors process behavior in real time. If a process starts behaving suspiciously—such as encrypting files en masse—it automatically stops it before it causes harm.
→ Privileges and access control Through its PAM (Privileged Access Management) module, Heimdal limits user and application permissions, drastically reducing the potential impact of an attack that manages to enter the system.
→ Centralized management panel Everything from a single console: complete visibility of the organization’s security status, real-time alerts and detailed reports for IT and compliance teams.

The 3-2-1-1-0 backup rule against ransomware
Because modern ransomware attacks the backup before encrypting production, the classic 3-2-1 rule is no longer enough. The current version is 3-2-1-1-0: three copies of the data, on two different media types, one off site, one immutable or offline, and zero errors on restore verification.
The last two numbers are the ones most often missing in practice. The immutable copy is what stops a compromised credential from deleting or encrypting the backup along with everything else. And zero errors means actually testing a restore, not just confirming the job ran — many companies discover their backup does not restore on precisely the day they need it.
What to do in the first hours of an incident
The first decision is containment: isolate affected machines from the network without powering them off, because shutting down can destroy evidence held in memory and, in some cases, the encryption key itself. Then cut off access for compromised accounts and preserve the logs before automatic rotation erases them.
The decision on whether to pay should be made before the incident, in writing, with legal and leadership. Mid-crisis, with operations halted, nobody decides it well. Worth remembering: paying does not guarantee the key, does not prevent disclosure of data already exfiltrated, and in several jurisdictions creates legal exposure of its own.

Frequently asked questions about ransomware
What is ransomware?
It is an attack that encrypts a company’s data and demands payment to release it. Modern variants combine that with extortion: before encrypting, the attackers copy the data and threaten to publish it, so having a backup no longer removes the leverage.
Is having a backup enough protection?
No, because modern ransomware targets the backup first. At least one copy must be immutable or offline, beyond the reach of a compromised credential — and the restore has to be genuinely tested, not merely confirmed by the job report.
What is the 3-2-1-1-0 rule?
Three copies of the data, on two different media types, one off site, one immutable or offline, and zero errors on restore verification. It is the evolution of the classic 3-2-1 rule, adapted to the fact that backups themselves became a target.
What should you do in the first hours of an attack?
Isolate affected machines from the network without powering them off, so evidence in memory is not destroyed; cut access for compromised accounts; and preserve logs before automatic rotation. The decision on whether to pay should already exist in writing, agreed with legal and leadership before any incident.
Which protection layers should you buy, and where?
The three that reduce risk most are endpoint protection with behavioural detection, backup with an immutable copy, and patch management. Aufiero Informática distributes security, backup and asset management software across Latin America with local support, and helps assemble those three layers in proportion to the size of the operation.
