In recent times, the level of danger of ransomware attacks is increasing. Businesses “have a headache” with the choice of whether to pay the hacker ransom or not. Without understanding how to attack, businesses are easy to fall victim to them. Understanding that, the following article will share about 10 ways ransomware attacks are considered the most dangerous. And introduce to readers the solution VNIS (VNETWORK Internet Security) to help protect businesses against the most dangerous ransomware attacks.
Top 10 most dangerous ransomware attacks that VNIS has to face
In the past, ransomware was a relatively simple matter. Attackers only infiltrate the organization’s systems and encrypt important data. Without backups, that organization would face paying a hefty ransom in the hope of decrypting those data.
But now, businesses have regularly backed up important data. So the risk of paying a ransom is much lower than it used to be. As a result, cybercriminals have turned to other more dangerous tricks to demand ransom.
1. Data Disclosure Statement
Disclosure of data (double blackmail) is a very common tactic used by hackers. The obtained data will be publicized by hackers or even auctioned if the victim does not pay the ransom. Therefore, even if there are backups, the victim will still choose to pay the ransom.
2. Direct contact with staff
To put pressure on an organization, cybercriminals will contact employees or senior executives of the business to make threats. They warn that personal data will be leaked if the organization / business does not pay the ransom.
3. Reach out to partners, customers and the media
In other cases, attackers will reach business partners, business customers or even the media. This urges the injured party to promptly pay the ransom.
4. Warn victims not to contact the authorities
Many businesses will seek help from the authorities or other organizations. As a result, they can recover their data without paying a ransom. At the same time, through this way they can bring the attacker to justice. Therefore, to avoid those consequences, cybercriminals will warn victims to keep them quiet.
5. Bribing insiders
Cybercriminals will bribe the employees of organizations to help them infiltrate the systems of that business. As a result, they can easily perform ransomware attacks. In return, the attackers promise to pay these people a sizable amount of money. Specifically, they will find employees who are dissatisfied with the company. Or dishonest employees who are willing to betray the business.
6. Change the password
After entering the system, many ransomware operations will set up a new administrator account. At the same time they will change the passwords of all the administrator accounts of the enterprise. This makes it impossible for them to log into the system, solve problems or restore encrypted files from backups.
7. Deployment of fraudulent activities
As noted by a security organization from the UK, hackers will send phishing emails to employees in the company. The purpose is to trick them into installing malware. They will then infiltrate and hijack email accounts. The attacker will communicate with other employees in the business using that email account. If they don’t pay the ransom, they will continue to carry out other attacks.
8. Delete backups
Attackers will delete backups or remove backup software of the enterprise once they have infiltrated the system. In some cases, hackers hijack the administrator account’s access. They then access the server that stores the victim’s online backups and delete the backups.
9. Mass distribution of ransom notices
Some cybercriminals will flood offices with ransom notes. They will send ransom notices to printers or terminals of businesses and businesses.
10. Incorporating Distributed Denial of Service (DDoS) Attacks
To force “stubborn” organizations to pay ransom, some ransomware gangs have combined with DDoS attacks. These attacks will bring down the enterprise’s web servers. And the team of technicians must allocate resources to handle the problem. Leads to disruption of their daily work and that of the business.
Ransomware Warning
Therefore, to protect your business against ransomware attacks, you can adopt some of the following methods:
- Train employees so they can distinguish emails that have been infected with ransomware.
- 24/7 monitoring to report suspicious activities.
- Check for spying activities in the company.
- Continuously monitor and update the network security situation of the enterprise. From there, come up with effective ransomware prevention plans.
- Disable all sessions of the Internet-connected Remote Desktop Protocol (RDP) to prevent hacker access. If employees need remote access, put it behind a VPN or untrusted connection. Also make sure multi-factor authentications are still working.
- Regularly back up important data, at least one offline. Combine applying the 3-2-1 method when backing up. Specifically, backing up 3 copies of data using two different systems. Including 1 offline version.
- To prevent attackers from disabling security, switch to software or apps that have a cloud storage management console that offers MFA. And you can do role-based administration to restrict access.
- Develop effective incident response plans and update as needed.
