MacOS Malware
macOS malware includes viruses, trojan horses, worms and other types of malware that affect macOS, Apple's current operating system for Macintosh computers. macOS (previously Mac OS X and OS X) is said to rarely suffer malware or virus attacks, and has been considered less vulnerable than Windows. There is a frequent release of system software updates to resolve vulnerabilities. Utilities are also available to find and remove malware. History Early examples of macOS malware include MP3Concept (discovered 2004, a benign proof of concept for a trojan horse), Leap (discovered in 2006, also known as Oompa-Loompa) and RSPlug (discovered in 2007). An application called MacSweeper (2009) misled users about malware threats in order to take their credit card details. The trojan MacDefender (2011) used a similar tactic, combined with displaying popups. In 2012, a worm known as Flashback appeared. Initially, it infected computers through fake Adobe Flash Player install prompts, but i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Virus
A computer virus is a type of malware that, when executed, replicates itself by modifying other computer programs and Code injection, inserting its own Computer language, code into those programs. If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses. Computer viruses generally require a Computer program, host program. The virus writes its own code into the host program. When the program runs, the written virus program is executed first, causing infection and damage. By contrast, a computer worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the Computer program, host program, but can run independently and actively carry out attacks. Virus writers use social engineering (security), social engineering deceptions and exploit detailed knowledge of vulnerability (computing), security vulnerabilities to initially infect systems an ...

A graphical user interface was originally added in OS X Mountain Lion (10.8) but was backported to Lion with the 10.7.5 update. Functions Configuration In the security & privacy panel of System Preferences, the user has three options, allowing apps downloaded from: The command-line utility provides granular controls, such as custom rules and individual or blanket permissions, as well as an option to turn Gatekeeper off.

KeRanger
KeRanger (also known as OSX.KeRanger.A) is a ransomware trojan horse targeting computers running macOS. Discovered on March 4, 2016, by Palo Alto Networks, it affected more than 7,000 Mac users. KeRanger is remotely executed on the victim's computer from a compromised installer for Transmission, a popular BitTorrent client downloaded from the official website. It is hidden in the .dmg file under General.rtf. The .rtf is actually a Mach-O format executable file packed with UPX 3.91. When users click these infected apps, their bundle executable Transmission.app/Content/MacOS/Transmission will copy this General.rtf file to ~/Library/kernel_service and execute this "kernel_service" before any user interface appearing. It encrypts the files with RSA and RSA public key cryptography, with the key for decryption only stored on the attacker's servers. The malware then creates a file, called "readme_to_decrypt.txt", in every folder. When the instructions are opened, it gives the victim dire ...

Difficult-to-trace Digital currency, digital currencies such as paysafecard or Bitcoin and other cryptocurrency, cryptocurrencies are commonly used for the ransoms, making tracing and prosecuting the perpetrators difficult. Sometimes the original files can be retrieved without paying the ransom due to implementation mistakes, leaked cryptographic keys or a complete lack of encryption in the ransomware. Ransomware attacks are typically carried out using a Trojan horse (computing), Trojan disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. However, one high-profile example, the WannaCry worm, traveled automatically between computers without user interaction. Starting as early as 1989 with the first documented ransomware known as the AIDS (Trojan horse), AIDS trojan, the use of ransomware scams grew inter ...

Keydnap
OSX.Keydnap is a MacOS X based Trojan horse that steals passwords from the iCloud Keychain of the infected machine. It uses a dropper to establish a permanent backdoor while exploiting MacOS vulnerabilities and security features like Gatekeeper, iCloud Keychain and the file naming system. It was first detected in early July 2016 by ESET researchers, who also found it being distributed through a compromised version of Transmission Bit Torrent Client. Technical details Download and installation OSX.Keydnap is initially downloaded as a Zip archive. This archive contains a single Mach-O file and a Resource fork containing an icon for the executable file, which is typically a JPEG or text file image. Additionally, the dropper takes advantage of how OS X handles file extensions by putting a space behind the extension of the file name for example – as “keydnap.jpg ” instead of “keydnap.jpg”. Usually commonly seen icon images and names are used to exploit users' willingne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
