Trojan For Mac Os
2021年2月27日Download here: http://gg.gg/ogrm0
A Trojan Horse, in the computer world, is a potentially devastating type of malware that disguises itself as something desirable in order to be installed or downloaded onto a computer system. Once the Trojan program has been installed, it goes to work with its true purpose, executing malicious activities that greatly compromise the overall security of the system. If your Mac has been infected by a Trojan Horse, the program could do any number of things to the system—from initiating the installation of other viruses or malware programs, to giving a hacker complete remote control of your system.Needless to say, a Trojan Horse is bad news for both you and your computer. But what can you do to avoid this type of malware and the headache it brings, or to detect and delete it from your Mac once you

Read on to learn more about this particularly malicious type of malware.The Root of the “Trojan Horse” NameDuring the Trojan War, after a lengthy siege of Troy, the Greeks decided to try to trick their enemies in order to get inside the seemingly impregnable walls of the city. Pretending to sail away in defeat, the Greeks constructed a giant horse and secretly hid soldiers inside. The Trojans, thinking themselves victorious in the war, pulled the horse inside the walls of Troy as a trophy of their triumph. At nightfall, the host of Greek soldiers hiding in the horse emerged and opened the gates of Troy, letting the rest of their army into the city, catching the Trojans off guard, slaughtering the Trojan army, and winning the war.Trojan Horse programs use the same basic concept as the Greeks did to get inside Troy. These programs work by tricking a computer user into willfully downloading and running a disguised piece of malware, which activates malicious processes on your computer once it has been installed. The Trojan can be disguised as anything you might want to download, from a music or video file on a torrent site, to a third-party program. In other words, the best way to avoid a Trojan Horse is to be careful about what you are downloading and where you are downloading it from. Don’t click links from people or websites you don’t trust, download your software from the Mac App Store instead of from the internet, and avoid torrent sites and other P2P download networks.Trojans on Mac: Do You Need to Worry?While Trojan Horses are nowhere near as common for Mac OS X as they are for Microsoft Windows, that doesn’t mean Mac users never have to deal with these kinds of covert attacks. On the contrary, back in 2012, a Mac-based Trojan called “Flashback” made a bunch of headlines—including this Mashable article, which claimed that over 600,000 Mac computers had been infected. In that case, the Trojan disguised itself as an installer for the Adobe Flash Player. Once implemented on a Mac machine, the Flashback Trojan would go to work searching the computer for passwords and personal information. The good news in the case of Flashback is that Apple was quick to solve the problem. Shortly after the Trojan Horse was discovered, Apple released a software update with a security patch that specifically prevented the Trojan from activating its malicious processes. In other words, users could protect themselves from the Trojan or cure the issue by simply staying on top of all OS X software updates. Users should take this story as a lesson to always install updates promptly when they become available, as doing so may be the easiest and best way to take care of any past or future Mac Trojan problems.Other Types of Trojan HorsesWhile the Flashback Trojan was used for password and data theft, that use is just one of the many applications for which hackers have written Trojan Horse programs over the years. Trojans can also crash your computer, corrupt your files, connect with and infect other computers or devices on your network, hold your computer ransom and demand that you pay a fee to “unlock” your files, watch what you are doing on your screen, log your keystrokes, access your webcam, or install any other type of malware on the system—just to name a few possible effects of infection.Trojan Virus On MacAvoiding Trojan Horses on MacAs with other types of malware, you can detect most Trojans using a standard anti-virus or anti-malware program. With that said, keeping your Mac system updated is arguably an even more important safeguard for preventing Trojan Horse infection. It’s also not a bad idea to Google “Mac Trojans” every once in awhile, just to see if there are any types of Trojans that are currently causing problems for a lot of Mac users. Since Trojans are still relatively and blissfully unusual on Macs, most of the bigger Trojan programs that can infect OS X will be reported on by major tech publications. Staying aware of the cyber threats that are out there will help you be more conscious of your internet behavior and more tuned into any unusual symptoms your computer may be exhibiting.
(Editor’s note: This story corrects an earlier report that stated that the Macintosh operating system had become a target of a malicious Trojan Horse.)
Security experts on Friday slammed security firm Intego for exaggerating the threat of what the company identified as the first Trojan for Mac OS X.
On Thursday, Intego issued a press release saying it had found OS X’s first Trojan Horse, a piece of malware called MP3Concept or MP3Virus.Gen that appears to be an MP3 file. If double-clicked and launched in the Finder, the Trojan accesses certain system files, the company claimed.Trojan Mac Os X
While Intego said the Trojan was benign, it said future versions could be authored to delete files or hijack infected machines. In the release, and in subsequent telephone interviews, Intego was vague about the purported Trojan’s workings and its origins.
On Friday, Mac programmers and security experts accused the company of exaggerating the threat to sell its security software.
’They gave the impression that this is a threat, but it isn’t,’ said Dave Schroeder, a systems engineer with the University of Wisconsin. ’It is a benign proof of concept that was posted to a newsgroup. It isn’t in the wild, and can’t be spread in the wild. It’s a non-issue.’
’They are spreading FUD to sell their software,’ said Ryan Kaldari, a programmer from Nashville, Tennessee, referring to the shorthand for fear, uncertainty and doubt.
Rob Rosenberger of Vmyths said he’d seen virus hype many, many times, and if antivirus companies put out alarmist press releases, it’s for one of two reasons: ’Either they’re delusional or they’re trying to own the hysteria,’ he said. ’This has been going on for 16 years now.’
Rachel Keiserman, a tech-support person at Intego, denied on Friday that her company exaggerated the threat or was attempting a publicity stunt. ’It’s not a hoax or anything like that.’ She declined to comment further and pointed to a press release listing questions and answers, which defended the company’s decision to classify the issue as a threat.
’While the first versions of this Trojan Horse that Intego has isolated are benign, this technique opens the door to more serious risks,’ the company said. ’The exploit that it uses is both insidious and dangerous, and it is our duty as a vendor of Macintosh security solutions to protect our users. We don’t believe in waiting until the damage occurs, unlike some of our competitors.’
Technically, the threat isn’t a Trojan Horse by the standard definition: It isn’t a working piece of malicious code and can’t easily be spread to other computers, experts said. Instead, it is a demonstration of a possible threat.
’We’re talking about theoreticals here,’ said Schroeder. ’It is possible for OS X to be infested with Trojans, viruses and security issues, but until it is, they aren’t justified in raising the alarm.’
The demonstration contains a real MP3 file of someone laughing. When launched in jukebox software like iTunes, the MP3 file plays and nothing else happens. But if double-clicked in the Finder, the MP3 file plays and a warning is displayed.
The program can’t be spread by e-mail or through a file-sharing network unless it is compressed using software like Aladdin’s Stuffit. Failing to compress the MP3 file before sending it renders the software inoperative.
The program exploits a vulnerability that goes back to the original Mac operating system: The system allows programs to appear as a file. Programs can have any icons, names or file extension. In other words, users could be tricked into activating a malicious program, thinking they were opening a document, picture or song.
The vulnerability was exploited several times by Trojans authored for previous versions of the Mac OS.
Mac programmer Bo Lindbergh wrote the threat demonstration and posted a link on the comp.sys.mac.programmer.misc newsgroup on March 20. The link leads to a site in Sweden. The file has now been removed. Lindbergh didn’t respond to an e-mail requesting comment.
Symantec on Friday said it was aware of the software. ’It is a proof-of-concept Trojan that does affect the Mac platform; however, it is currently not present in the wild,’ the company said in a statement. It said it would continue to monitor the situation.Trojan Macos Client
Likewise, Apple spokeswoman Natalie Sequeira said the company was investigating. ’We are aware of the potential issue identified by Intego and are working proactively to investigate it,’ she said.
