Cyber attackers have noticed as mobile devices have gained greater acceptance as work tools EDR. As a result, an unprecedented surge of malware designed specifically to exploit smartphones and tablets has occurred.
Attackers can target Android and Apple devices, though Jailbroken iPhone owners are especially susceptible. Most attacks use phishing and spam tactics to deliver malicious code to compromised phones.
Drive-by downloads
Nonconsensual malware attacks on mobile devices occur when the device accesses an infected website that hosts malware downloads without user consent, including ransomware, keyloggers, backdoors, and even personal and banking details that can access personal accounts. These unwarranted downloads can deliver almost any malicious software onto an affected device, including ransomware, keyloggers, and backdoors that can ultimately compromise network systems and potentially access personal and financial details without user knowledge or consent.
Hackers employ drive-by downloads to spread malware by exploiting vulnerabilities in Web browsers, plug-ins, and operating systems that users fail to apply promptly as security updates emerge. Exploit kits offer prepackaged collections of attacks and exploits for hackers looking to take advantage of such vulnerabilities.
Attackers can deliver these threats through phishing emails, text messages, and social media posts that look legitimate but contain malicious downloads that install themselves while the victim browses the internet. Such campaigns could also use this tactic to persuade victims to install fake antivirus software or other harmful applications on their devices.
Though no attack can be prevented entirely, innovative cybersecurity practices can significantly decrease the risk. Installing security updates promptly, staying away from untrusted websites, and using tools like NoScript and an ad blocker all help mitigate attack vectors that attackers could exploit.
Avoid sketchy websites, particularly those dealing with pirated or adult content, as cybercriminals can easily compromise these. Furthermore, users are advised against logging in as admins as this reduces how many read and write privileges malware has once it infiltrates their device.
Ensure employees are running the latest versions of their browsers and extensions - drive-by downloads can happen through older software products that contain vulnerabilities that attackers exploit; making sure all employees use current plug-in versions will dramatically reduce infection risks.
Mobile Malware Phishing
Attackers typically employ deception to lure victims into clicking on malicious links or attachments and downloading malware, using email, SMS messages (Smishing), in-app messaging services such as WhatsApp, and insecure Wi-Fi networks - even USB drives containing infected material can deliver such attacks.
Once an infected device has been compromised, malware can easily record phone calls and access sensitive data stored on it - such as contacts, browser history, and applications - before gathering GPS coordinates and uploading them back to an attacker's command-and-control server. Such tools are known as remote-access tools (RATs) and provide criminals with valuable intelligence about device owners and users.
Organizations reliant on mobile devices to conduct business or permit employees and visitors to bring in their mobile phones must ensure adequate protection, especially with phishing attacks increasing at an alarming rate.
Attackers can leverage users' tendencies not to investigate sources for links on smartphones as much, making it easier for them to click if something looks tempting. This attack could result in credential theft, device compromise, and ransomware infections - potentially serious issues for businesses and users.
Utilizing secure Wi-Fi can be an easy and effective way to protect against these threats and may prevent third parties from spying on your connection and performing man-in-the-mobile exploits. Furthermore, password-protected VPNs prevent attackers from hijacking and accessing data that passes over it.
Mobile malware not only steals information but can also use its devices to steal user credentials. Banking trojans have become an increasing threat, targeting those who prefer conducting financial transactions from their smartphones - such as money transfers and bill payments - over other channels. They may sneak into trusted applications or fake versions of bank apps to intercept login and password information before it reaches a bank server.
Many attacks can be prevented with three simple steps - using caution when accessing content, installing an antivirus program, and reporting any phishing attacks that come your way.
Businesses reliant on mobile devices to conduct their work should implement a comprehensive threat detection and response solution incorporating mobile device management (MDM), machine learning capabilities, and detection. This approach offers maximum protection against potential phishing attempts in their tracks.
Mobile Malware Rooting
Rooting gives malware complete access to an operating system, enabling it to install malicious apps without restriction or monitoring. Malware can then steal information, modify the firmware, and even erase memory - while hackers could use their mobile devices as an attack platform against local networks. As more mobile devices enter workplace environments, cyber attackers have taken notice and developed numerous attack methods against mobiles - though overall mobile malware volumes may be lower than desktops but remain an existential threat.
At times, attackers take advantage of known vulnerabilities in mobile operating systems to exploit and spread different forms of mobile malware, such as worms, Trojan horses, spyware, and ransomware. Such exploits can be found anywhere, ranging from third-party app stores and official software sources to third-party app stores and stores selling apps that provide them.
Though these techniques are widespread, mobile malware can spread in many other ways. One method involves stealing users' credentials and sending them directly to a remote server for processing, typically found embedded into legitimate apps that users download and open or launch; this form of mobile malware activates when the user opens the file or application.
Other threats include synchronizing calendars, notes, or sensitive information with remote servers for processing; certain Trojans even demand money to decrypt it!
Malware may even be installed onto mobile devices by manufacturers; one study revealed that more than half of Android phones sold in China were preloaded with malware.
Mobile malware can also spread via unauthorized app downloads. This typically involves installing apps from Google Play and Amazon Appstore that appear helpful but contain malware - for instance, CopyCat was spread through apps posing as password managers, app launchers, and data savers downloaded over 10,000 times from these stores alone!
Mobile malware spread through other means involves abusing operating system permissions by granting too many permissions to applications. You must read over their permission requests before authorizing them to access personal or system files on your device.
Mobile Malware Adware
Adware is software that displays pop-up ads, redirects users to malicious websites, and uses device data for targeting advertisements. It typically generates income for cyber criminals via pay-per-click ads, pay-per-view videos, or pay-per-install schemes. It may steal login credentials, account information, and locations so hackers can use them against users.
Mobile Adware can be hard to detect because it often hides within legitimate apps that appear safe. Social engineering techniques used in mobile Adware may make users click without realizing they have. Fake close buttons, strategically placed accept function keys and unexpected pop-ups are deception tactics used to trick unsuspecting users into clicking malicious links. Keep an eye out for suspicious charges on your bank statement if you believe you may have contracted mobile Adware.
Many users are unaware that free apps downloaded from an app store could contain Adware. Hackers use vulnerabilities in operating systems or software to hide Adware on computers and mobile devices, giving hackers access to personal data and passwords. Attacks typically begin with emails or text messages masquerading as legitimate entities to gain trust before coaxing victims into downloading an unsafe app or visiting malicious websites that install malware onto their systems.
Once installed, Adware takes complete control of a user's device and starts communicating with one or more command and control servers, managed, and controlled by cybercriminals known as botmasters who extract login details before sending instructions directly to infected devices. Some mobile adware is tailored specifically for use on cell phones, including viruses, worms, Trojan spyware, or ransomware.
Mac users had long enjoyed relative peace of mind as cyber criminals predominantly targeted Windows devices to spread infections at scale. As more mobile users opt for MacBooks over desktop PCs, hackers have started targeting them too; fortunately, Apple's anti-malware technology, Gatekeeper, protects Macs against unwanted programs like Adware from installing themselves onto Mac computers.
