If they succeed in accessing the domain controller, the attacker can then deploy ransomware such as Ryuk, which encrypts the organization’s data and demands the ransom. This second layer of malware then spreads laterally through the company, stealing credentials, deploying backdoors and, perhaps most importantly, trying to access the domain controller.
But attackers can also use it to spread other malware, like TrickBot or Qbot.

If the recipient opens the attached file or clicks on the URL, they unknowingly download the trojan, which then has the power to steal sensitive data. Trojans like Emotet are primarily spread through spam mails.

Emotet is a particularly infamous trojan that was first identified in 2014, and has recently reared its ugly head in a series of attacks that cause it to be one of the most prevalent ongoing threats that organizations are currently facing, according to a warning issued by the CISA. A trojan is a type of malware that tricks victims into thinking it’s harmless by disguising itself as legitimate software. In both cases, the attacker demands payment, threatening to publish sensitive information or permanently remove data from the system if the victim fails to pay up.īut how does ransomware get onto your system in the first place? Locker-ransomware works in much the same way, except that it prevents users from accessing the files instead of encrypting them, before demanding a ransom for the data to be “unlocked”. Crypto-ransomware encrypts an organization’s data and demands a ransom in order to have the files decrypted and safely returned. There are two main types of ransomware: crypto-ransomware and locker-ransomware. With bad actors constantly finding new ways to evade security layers, it’s inevitable that most companies will face a ransomware attack at some point.īut how do attackers find their way into your systems in the first place, and what can you do to recover from a ransomware attack? What Is Ransomware And How Does It Work? And unfortunately, attack incidents aren’t only on the rise they’re also becoming increasingly sophisticated.
The same study found that the number of ransomware attacks saw a global year-to-date increase of 148%, making 2021 the most dangerous and costly year for ransomware the company has ever recorded. Notoriously difficult to keep patched against vulnerability exploits, IoT devices can create a huge weakness within a company’s infrastructure when not properly managed-and when connected to the network without permission from the IT team, these vulnerabilities can easily go unnoticed.
But 2021 saw a global 33% increase in malware targeting IoT devices. IoT devices are becoming increasingly popular in the workplace, as organizations welcome the use of smart devices, such as security cameras and coffee machines, that are designed to help us live and work more efficiently. And if any of those devices are infected, that threat can easily spread to other systems once the device is reconnected to the corporate network.īut that’s not the only risk organizations are currently facing. These employees are bringing devices with them that may have been connected to unsecured networks, used for personal purposes, or shared with partners over the last two years-all of which leave them vulnerable to malware exploits. Once downloaded to the user’s device, the malware holds corporate data hostage, locking users out or rendering it indecipherable through encryption, until the organization pays a ransom to restore it.Ĭybercriminals are known to take advantage of uncertainty and change, and the global workplace has experienced huge changes in recent years first, as the COVID-19 pandemic catalyzed the shift to remote work, and now, as many organizations welcome their employees back into the office in a hybrid working format.
Ransomware is a type of cyberattack involving malware.
