Recently, Jérôme Segura forwarded me a link to a fake virus scam page that seemed to be Mac-related. I began to look into it, and very quickly found myself in a deep rabbit-hole of Mac crapware, all from a major developer of Mac PUPs (potentially unwanted programs), PCVARK.

A colleague referred me to an article on a piece of cross-platform malware, called Adwind RAT (short for “remote access tool”), that was going undetected.
This is often code for “this malware was written in Java,” which doesn’t necessarily mean that it actually drops a Mac payload. So I was a bit skeptical, and said so. But, hey, new malware to play with… how could I resist taking a peek?

A new piece of malware for Mac OS X has been discovered, according to a blog post from Bitdefender.
This malware, which Bitdefender is calling Backdoor.MAC.Eleanor, is only the second piece of true Mac malware spotted so far in 2016, the first being the KeRanger ransomware. (Of course, this is not taking the widespread and increasing plague of Mac adware into account.)

Graham Cluley drew my attention the other day to an issue that has apparently been known to some for years, but was new to me: clipboard poisoning, an issue where a website can replace what you think is on your clipboard with something else.
Although this seems like an insignificant issue on first glance, it turns out that there are some very serious implications.

Ransomware – malicious software that encrypts your files and then demands payment to unlock them – has become a major scourge of the Windows world.
Mac users just had their first brush with such threats last week, with the appearance of the KeRanger ransomware. However, shortly before KeRanger, I encountered a ransomware event in the Mac world far worse than anything seen for Windows.
This hack seems to have turned an iMac into an expensive paperweight.

On Saturday, Apple quietly added detection of something called “KeRanger” to the XProtect anti-malware definitions in OS X. It was revealed on Sunday by Claud Xiao of Palo Alto Networks that KeRanger is the first real Mac ransomware, and it’s not just theoretical. It’s in the wild.

Much has been said in the security world about the recent release of data on vulnerabilities discovered in 2015. Due to the way this data has been presented, many news outlets have been reporting that Mac OS X was the “most vulnerable” OS in 2015. But was it really?

Kromtech, the developer of MacKeeper, has suffered a major breach that has exposed more than 13 million users’ data.
Chris Vickery, a security researcher who has uncovered a number of similar data breaches in the past, found that a Kromtech database full of sensitive data was accessible over the internet… without any login required.

Mac users began to have problems opening apps downloaded from the App Store Wednesday morning. This caused messages that the apps were damaged and would need to be re-downloaded from the App Store.
It turned out that the problem was an expired cryptographic certificate at Apple, used to verify the legitimacy of these apps. Apple didn’t renew it in time, and when it expired, App Store apps failed.

It seems that MacUpdate, long considered to be one of the only remaining trustworthy download aggregation sites for the Mac, has succumbed to the same plague that has ruined most of the others: adware.
