Malware & other nasty IT / cyber things

[OUTLAW 09]

Experts from security firm Sixgill have discovered a new strain of the macOS Proton RAT that is offered for sale on Russian cybercrime underground.

The Dark Web is the right place where to find any kind of illegal products and services, malware such as banking trojan and spyware are very popular in cyber criminal underground.

Recently a new remote access tool (RAT) specifically designed to infect macOS systems is currently being advertised on Russian cybercrime underground. The researchers at security firm Sixgill discovered the advertising on crime forums and on a custom website, this threat is also described in videos published on YouTube.

The Proton homepage went down just after the experts at Sixgill published the report.

“Sixgill researchers have encountered a post in one of the leading, closed Russian cybercrime message boards. The author of the thread announced a RAT dubbed Proton, intended for installation exclusively on MAC OS devices. The author offered this product in one of the leading underground cybercrime markets.” reads a report published by Sixgill.

The Proton RAT first appeared in the threat landscape last year, the variant recently advertised on hacking forums includes many features such as the ability to execute console commands, access the user’s webcam, log keystrokes, capture screenshots and open SSH/VNC remote connections. The malicious code is also able to inject malicious code in the user’s browser to display popups asking victims information such as credit card numbers, login credentials, and others.

“The malware includes root-access privileges and features allowing an attacker to obtain full control of the victim’s computer. Its capabilities include: running real-time console commands and file-manager, keylogging, SSH/VNC connectivity, screenshots, webcam operation and the ability to present a custom native window requesting information such as a credit-card, driver’s license and more. The malware also boasts the capability of iCloud access, even when two-factor authentication is enabled.” continues the report.

According to the author, macOS Proton RAT is written in native Objective-C and it is fully undetected by any existing MAC OS antivirus solution.

Below the list of features described in the ad:

macOS Proton RAT

The Proton RAT has root access and is able to elude standard macOS security features, it is also able to bypass two-factor authentication on iCloud accounts.

Researchers speculate macOS Proton RAT leverages a zero-day vulnerability in macOS, but most interesting characteristic of the threat is that the malicious code is signed with genuine Apple code-signing certificates. It is likely the author has managed to falsify registration to Apple Developer ID Program or has stolend the credentials to an apple developer.

“The real threat behind the software is this: The malware is shipped with genuine Apple code-signing signatures. This means the author of Proton RAT somehow got through the rigorous filtration process Apple places on MAC OS developers of third-party software, and obtained genuine certifications for his program. Sixgill evaluates that the malware developer has managed to falsify registration to the Apple Developer ID Program or used stolen developer credentials for the purpose.” reads the report.

The price for the macOS Proton RAT ranged from $1,200 to $830,000 for the entire project (an absurd price). Below the version advertised on the Proton websites:

Standard Edition

I) License to control only ONE remote machine 1) 1 BTC — unsigned 2) 2 BTC — signed
II) License to control 20 remote machines 1) 10 BTC — unsigned 2) 11 BTC — signed
III) License to control infinite remote machines 1) 66 BTC — unsigned 2) 76 BTC — signed

Extended edition

I) License to control infinite remote machines 1) 166 BTC — unsigned 2) 200 BTC — signed
II) License to control infinite remote machines on your own server 1) 366 BTC — without source code 2) 666 BTC — with full source code

Researchers noticed that the authors of the malware try to disguise their spyware as legitimate surveillance software.

The Sundown EK has been inactive since early this year, the Terror EK is being very popular in the cybercriminal ecosystem.

One year ago the Angler EK and Nuclear EK disappeared from the threat landscape, while the Sundown EK was conquering the criminal underground.

What’s happening now?

The Sundown EK has been inactive since early this year, the Terror EK is being very popular in the cybercriminal ecosystem.

Last week, Cisco Talos published an analysis of Sundown EK, the expert detailed the improvements of the EK that presented many similarities with the RIG exploit kit.

“Sundown is an exploit kit in transition, it has stopped using calling cards and other easily ways to identify its activity. It is one of the few exploit kits adding any new exploits to their arsenal, albeit stolen. At the same time they consistently steal exploits and technologies from other people and competitors.” reads the analysis of the Talos group. “The exploit kit landscape has been struggling to find its footing since the major players have left. It still appears to be in transition with RIG and Sundown being the primary players left as an option for those looking to compromise random victims while browsing the web.”

The Sundown EK was not sophisticated like other large exploit kits.

Security experts at Talos were noticing a long inactivity of the Sundown EK, also variant of the kit was disappeared from the scene, including Bizarro and Greenflash.

This silence leads the experts into believing that threat actor ceased the operations.

“Many security researchers tracking exploit kits have noted the lack of Sundown EK activity for several weeks now. A post from Cisco’s Talos team came off as a bit of a surprise at the end of March (Threat Spotlight: Sundown Matures), but any doubts were squashed by this tweet on April 8th (Sundown (Beps) and Nebula out ? More than one month since last hits).” reads a blog post published by MalwareBytes.

“Also, whatever happened to Bizarro and Greenflash Sundown EKs? Whether this is a temporary break or yet another dead EK, time will tell.”

Recently experts observed a significant increase of hacking campaigns leveraging the Terror EK.

Because of similarities with Sundown EK, experts at MalwareBytes initially thought that the Terror EK was simply a new variant of Sundown, but further investigation revealed that it was actually from a different actor (so-called Terror EK by Trustwave).

The Terror EK was advertised on various underground forums by a hacker with the online moniker @666_KingCobra that is offering it for sale under different names (i.e. Blaze, Neptune, and Eris).

Experts at Malwarebytes Labs said that the Terror EK was used in a malvertising campaign distributing the Smoke Loader by exploiting Internet Explorer, Flash, and Silverlight exploits.

The Terror EK was also involved in a newer campaign using a different landing page that distributes the Andromeda malware.

The compromised websites are leveraged to redirect to the exploit kit landing page via server 302 redirect call and done via script injection.

Terror EK

“Sundown EK was notorious for stealing exploits from others and the tradition continues with more copy/paste from the ashes of dead exploit kits. If this harvesting was done on higher grade EKs, we would have a more potent threat but this isn’t the case here,” Malwarebytes concludes.
