Sounds great, right? Everyone working together for the greater good, sharing the fruits of their labor with each other.

For the most part, it is great. Any contribution to the source code is up for scrutiny, but there have been instances where malicious code has made its way to the end user.

To that point, in July of cryptomining malware was found inside of an app or "snap," as they call it in the world of Linux for Ubuntu and other Linux -based operating systems. Canonical, the developers of Ubuntu admitted, "It's impossible for a large-scale repository to only accept software after every individual file has been reviewed in detail. Malwarebytes Labs defines exploits as, "known vulnerabilities in software that can be abused to gain some level of control over the systems running the affected software.

So are backdoors and exploits one in the same? Exploits are accidental software vulnerabilities used to gain access to your computer and, potentially, deploy some sort of malware. To put it another way, exploits are just software bugs that researchers or cybercriminals have found a way to take advantage of. Backdoors, on the other hand, are deliberately put in place by manufacturers or cybercriminals to get into and out of a system at will.

Here's a look back at some of the most in famous backdoors, both real and fictional since the dawn of computers. One could argue backdoors entered the public consciousness in the science fiction film WarGames , starring Matthew Broderick in what feels like a test run for Ferris Bueller. Broderick as mischievous teenage hacker David Lightman uses a built-in backdoor to gain access to a military supercomputer designed to run nuclear war simulations.

Unbeknownst to Lightman, the schizophrenic computer can't tell reality from simulation. And also some genius decided to give the computer access to the entire United States nuclear arsenal.

Hilarity ensues as the computer threatens to blow up the entire world. In the NSA developed an encryption chip with a built-in backdoor for use in computers and phones.

Supposedly, the chip would keep sensitive communications secure while allowing law enforcement and government agencies to decrypt and listen in on voice and data transmissions when warranted. Hardware backdoors have big advantages over the software kind. Namely, they are harder to remove—you have to rip the hardware out or re-flash the firmware to do so.

The chip, however, was derailed over privacy concerns before seeing any kind of adoption. In Sony BMG got into the business of backdoors when they shipped millions of music CDs with a harmful copy protection rootkit. Designed to monitor your listening habits, the Sony BMG rootkit would also stop you from burning CDs and left a gaping vulnerability in your computer that cybercriminals could take advantage of.

Sony BMG paid out millions to settle lawsuits related to the rootkit and recalled even more millions of CDs. In several Netgear and Linksys routers were found to have built-in backdoors. SerComm, the third-party manufacturer that put the routers together, denied putting the backdoors in their hardware on purpose.

But when the patch SerComm released ended up hiding the backdoor instead of fixing it, it became clear the company was up to no good. Exactly what SerComm was trying to accomplish with the backdoor remains unclear. That same year software developers working on a spinoff of Google's Android operating system called Replicant discovered a backdoor on Samsung mobile devices, including Samsung's Galaxy series of phones.

The backdoor allegedly allowed Samsung or anyone else who knew about it remote access to all of the files stored on affected devices. In response to the discovery, Samsung referred to the backdoor as a "feature" that posed "no security risk.

The other famous phone maker, Apple, refuses to include backdoors in its products, despite repeated requests from the FBI and US Department of Justice to do so. Pressure mounted following the San Bernardino terrorist attacks in which the FBI recovered an iPhone owned by one of the shooters.

Instead of compromising the security of their iOS devices, Apple doubled down on privacy and made their iPhones and iPads even harder to crack. The FBI eventually withdrew their request when they were able to hack the older, less secure iPhone with the help of a mysterious third party. Plugins containing malicious hidden code for WordPress, Joomla, Drupal and other content management systems are an ongoing problem. In security researchers uncovered an SEO scam that affected more than , WordPress websites.

Once installed, Simply WordPress opened up a backdoor, allowing admin access to the affected websites. From there, the hacker responsible embedded hidden links to his sketchy payday loan website other websites linking back to your website is great for SEO. Download Microsoft Edge More info.

Furthermore, backdoors can allow code and commands to be executed on your device or monitor your web traffic.

Exploits are programs that contain data or code that take advantage of a vulnerability within an application on your computer. Rootkits are designed to conceal certain objects or activities in your system.

Often their main purpose is to prevent malicious programs being detected, in order to extend the period in which the programs can run on an infected computer. One of the best-known dropper Trojans is the Emotet malware, which has now been rendered harmless but which, in contrast to a backdoor Trojan, cannot execute any code on the PC itself.

Instead, it brings other malware with it, for example the banking Trojan Trickbot and the ransomware Ryuk. Droppers are therefore similar to downloader Trojans, the difference being that downloaders need a network resource to pull malware from the network. Droppers themselves already contain the other malicious components in the program package. Both types of Trojan can be remotely updated in secret by the programmers responsible, for example so that virus scanners cannot detect them with new definitions.

New functions can also be added in this way. Banking Trojans are among the most widespread Trojans. Given the increasing acceptance of online banking, as well as the carelessness of some users, this is no wonder — they are a promising method for attackers to get their hands on money quickly.

Their goal is to obtain the access credentials to bank accounts. To do this they use phishing techniques, for example by sending the alleged victims to a manipulated page where they are supposed to enter their access credentials.

Accordingly, when using online banking you should ensure that you use secure methods for verification, such as only the app of the respective bank, and never enter your access data on a web interface. Distributed denial-of-service DDoS attacks continue to haunt the web. In these attacks, a server or network is torpedoed with requests, usually by a botnet.

In mid-June , for example, Amazon fended off a record attack on its servers. For over three days, Amazon's web services were targeted with a data throughput of 2. There must be an enormous botnet to achieve that kind of computing power. Botnets consist of zombie computers, so to speak. On the face of it they are running normally, but they are also functioning silently as attackers.

The reason for this is a Trojan with a backdoor component that slumbers unnoticed on the computer and, if necessary, is activated by its operator. If a botnet attack or a DDoS attack is successful, websites or even entire networks are no longer accessible.

Fake antivirus Trojans are particularly insidious. Instead of protecting, they get every device into serious trouble. With alleged virus findings, they want to cause panic among unsuspecting users and persuade them to purchase effective protection by paying a fee.

But instead of a helpful virus scanner, the user only gets more problems, as their payment data is conveyed to the Trojan originator for further misuse. So if you suddenly get a virus warning in your browser when visiting a website, you should ignore this and only trust your system virus scanner.

This type of program steals user account information from online gamers. One could argue that these messengers are barely in use nowadays. However, even new messenger services are not immune to Trojans.
