As more and more people rely on their mobile devices for work and personal use, the risk of cyber attacks targeting these devices has become increasingly prevalent. One particularly dangerous type of attack that can cause significant damage is ransomware. In this article, we will explore the various techniques used by attackers to deploy ransomware on iOS and Android devices, as well as some best practices for protecting against such attacks.
Introduction
Before diving into the specific techniques used by attackers to deploy ransomware on mobile devices, it is important to understand what ransomware is and how it works. Ransomware is a type of malicious software that encrypts a victim’s files and data, rendering it inaccessible. The attacker then demands payment from the victim in exchange for providing the decryption key to unlock their files. This payment is often demanded in cryptocurrency, as it allows the attacker to remain anonymous and difficult to trace.
Types of Ransomware Targeting Mobile Devices
There are several different types of ransomware that can target mobile devices, including:
- Locky
- WannaCry
- Petya
- Samas
Locky
Locky is a ransomware strain that primarily targets Windows-based systems, but it has also been known to infect Android devices. It encrypts files on the victim’s device and demands payment in exchange for the decryption key.
WannaCry
WannaCry is a highly virulent ransomware strain that was first identified in 2017. It can target both Windows and Linux-based systems, as well as Android devices. WannaCry encrypts files on the victim’s device and demands payment in exchange for the decryption key.
Petya
Petya is another highly virulent ransomware strain that was first identified in 2016. It can target both Windows and Linux-based systems, as well as Android devices. Petya encrypts the victim’s device and demands payment in exchange for the decryption key.
Samas
Samas is a ransomware strain that primarily targets Windows-based systems, but it has also been known to infect Android devices. It encrypts files on the victim’s device and demands payment in exchange for the decryption key.
Attack Techniques Used by Attackers
Now that we have a better understanding of the different types of ransomware that can target mobile devices, let’s take a closer look at the techniques used by attackers to deploy these malicious programs.
- Phishing
- Exploits
- Malicious Apps
- Social Engineering
- Ransomware as a Service (RaaS)
Phishing
Phishing is a technique used by attackers to trick victims into clicking on a malicious link or attachment that downloads ransomware onto their device. This can be done through email, social media, or even text messages.
Exploits
Exploits are vulnerabilities in software that can be exploited by attackers to gain access to a victim’s device and install ransomware. These exploits can be found in both the operating system and third-party applications.
Malicious Apps
Malicious apps are apps that have been modified by attackers to include ransomware. These apps can be downloaded from untrusted sources, such as third-party app stores, and can infect a victim’s device without their knowledge.
Social Engineering
Social engineering is the practice of manipulating people into divulging sensitive information or taking certain actions that can lead to the installation of ransomware on their device. This can be done through phone calls, in-person interactions, or even fake job interviews.
Ransomware as a Service (RaaS)
Ransomware as a Service is a business model where attackers create and distribute ransomware, allowing other criminals to use it to infect victims and collect payments. This allows attackers to focus on developing new and more sophisticated malware, while the RaaS providers handle the distribution and support.
