Nasty Mac malware can steal your passwords and credit cards — what to do
Nasty Mac malware tin can steal your passwords and credit cards — what to do
Cybercriminals are corrupting Mac applications at the source, poisoning otherwise benign open-source projects with malware that contains 2 previously unseen zero-day exploits.
When you lot run the infected apps, they may direct y'all to dangerous websites, change the addresses on your cryptocurrency wallets, take screenshots of what you're looking at or steal your credit cards.

The malware also replaces Safari with a malicious version of Apple'southward browser, infects all other major browsers, steals Google, Apple ID and PayPal usernames and passwords, steals data from Skype, Telegram, Evernote and WeChat, and may even install ransomware.
To protect yourself, make sure you're running some of the best Mac antivirus software, because Apple'southward built-in defenses may not exist able to catch the malware. You too might desire to install apps just from Apple tree's own App Store for the fourth dimension existence.
The antivirus maker Trend Micro, whose researchers discovered the malware, calls information technology "a rabbit hole of malicious payloads" in a web log post last calendar week.
Browser massacre
Once the malware, which Trend Micro calls XCSSET, is in full force, it profiles the arrangement and infects any versions of the Brave, Firefox, Opera, 360 and Yandex browsers that may exist installed. If Google Chrome is installed, the malware replaces information technology with an older version of Chrome that has weaker security.
That's nada compared to what it does with Safari, however. The malware downloads and installs a malicious version of Safari and makes sure any internal links to the real Safari go to the imitation i instead.
"Functionally, this ways that the simulated Safari browser runs instead of the legitimate version of Safari," states a Trend Micro white newspaper on the XCSSET malware.
Then far, Trend Micro has seen XCSSET infecting only two Mac open-source projects, one from Republic of india and the other from China. It has not seen it infecting any iOS apps, although that would certainly exist possible.
It'due south happened earlier
If this sounds familiar, it'southward happened before. In 2015, a malicious version of Apple'due south development platform Xcode was distributed in China. The result was that any Mac or iOS apps created with the corrupted version of Xcode were themselves corrupted. Apple tree swiftly removed the tainted apps from its app stores.
Then how is information technology happening again? This time, the crooks are striking a fleck farther downstream. Instead of attacking Xcode itself, they're checking online code repositories similar GitHub, where dozens or hundreds of developers who don't really know each other tin can use Xcode to collaborate on a unmarried open-source projection.
"Malicious code is injected into local Xcode projects so that when the projection is congenital, the malicious code is run," Tendency Micro said.
Because the unwitting software developers release the applications with their own authorized signatures, the infected apps will non always be stopped by Apple tree's own built-in security safeguards.
"Methods to verify the distributed file (such every bit checking hashes) would not aid as the developers would be unaware that they are distributing malicious files," Trend Micro added.
