Stay informed and pay close attention to the language used in emails or on the websites you visit, especially if they ask you to download software. It’s better to be skeptical and double-check that you know what you are downloading or clicking on, so you don’t risk downloading a counterfeit program. After successfully doing that, the application was once again updated with a benign version so as not to stir suspicion.īecause the concept behind a Trojan is to trick users in an undetectable manner, they’re not always easy to catch, and Trojan infections are on the rise. After the malicious update reached the device and gained system privileges, it had the ability to covertly install applications from third-party marketplaces potentially malicious without the user’s knowledge. The application was submitted as a perfectly legitimate color block game, following which attackers would update it with malicious code. For example, there have even been rooting Trojans that managed to slip into Google Play. While some users might want to root their devices to either delete pre-installed applications that normally cannot be removed or even change the Android version the device is running, rooting Trojans are usually installed without a user’s” knowledge. Rooting Trojans are designed to take full remote control over a device, enabling the attacker to access any type of stored information, as if actually holding the device. While SMS-sending Trojans are usually quite popular, especially since they present an easy way of making money, rooting Trojans are among the most devious threats. If threats were traditionally targeting Windows and macOS, with more than 3 billion active Android devices in the world in 2022, it makes sense for cybercriminals to develop threats for Android smartphones. Whatever the vector, Trojans are the biggest single threat to Macs, and most of those attempted attacks were picked up in the US, which registered 36% of Trojan activity targeting macOS globally in 2021 – unsurprisingly so, considering the US has the biggest macOS install base in the world.Īndroid is no stranger to Trojans. On Macs, a fair amount of Trojan infections also occur through warez sites – hotbeds for pirated downloads. In 2021, despite international efforts to dismantle big-name Trojans like Trickbot, Emotet, Dridex and AgentTesla, cybercriminals continued to leverage this infamous malware family. Trojans are used extensively against high-profile Windows targets and remain on the map of the top threats to Windows computers globally. The delivery method for Trojans on any given platform typically involves social engineering techniques like spam and phishing, infected websites, or scams leveraging the victim’s favorite social networks. Trojans are the most common type of malware on both Mac and Windows. Ransomware is a species of malware specialized in encrypting user data and asking for ransom in exchange for the decryption key. Remote Access Trojans (RATs) are usually popular on Android, as they enable attackers to leverage seemingly legitimate applications to exploit vulnerabilities within the mobile operating system and take control of it.Īs of late 2014, a new family of Trojans made headlines in the media: ransomware. These malicious applications are highly specialized: they can provide remote access to a computer or smartphone, can be used to launch denial-of-service attacks, download other Trojans for other cyber-criminals or send spam e-mails from the infected devices. Trojans account for the bulk of currently existing malware and, unlike viruses or worms, they can neither infect files nor propagate across a network without user intervention. For instance, a Trojan operator would attempt to trick the user trying to watch video content (usually downloaded via P2P networks) to install a “special codec”, that ultimately proves to be a backdoor or a piece of ransomware. Just as the original Trojan horse deceived the people of Troy, so does the computer Trojan deceive the user by posing as legitimate software.Ī Trojan is a specific breed of malware that impersonates an application, utility, or software product in order to deceive the user into running it. Following the same analogy, a Trojan is a malicious program a hacker will use to break into a computer. The Trojan horse was a sly trick the ancient Greeks used to infiltrate their troops in Troy to ultimately conquer the city.
