Hackers Launching Ransomware and CryptoMiner via Love_You MalSpam Campaign

The worst alliance of Ransomware and the CryptoMiner family in a spread spree, early January 2019. Malware Spam or MalSpam is the term used to designate malware that is delivered via email messages.

Malicious spam (MalSpam) using zipped JavaScript (.js) files as email attachments–this is a well-established tactic used by cybercriminals to distribute malware. The infection traffic included GandCrab ransomware, a Monero (XMRig) cryptocurrency miner, and Phorpiex spambot traffic.

The email will be delivered with the initial JavaScript and it extracts an “exe” file. This file will download the dropper and the dropper gets the rest of the payloads from Command and Control.

In the last 2 days, there were many samples found and many are uploading new samples in public sandboxes. In “” a public sandbox, there are nearly 1200samples are uploaded and the spread seems to be high.

This GandCrab ransomware with CryptoMining seems to be critical and new variants of 2019. Get the IOC’s from your Cyber Intel and public sandboxes. The purpose of GandCrab, as with other ransomware, is to encrypt all or many files on an infected system and insist on payment to unlock them. The developer requires payment in cryptocurrency, primarily DASH, because of it complex to track, or Bitcoin.

Evolution of GandCrab Ransomware

                GandCrab v1 Ransomware, were discovered earlier in 2018. In nearly one month, over 50000 endpoints were infected and encrypted. Unusually, this ransomware asked to pay ransom in the cryptocurrency format “DASH”.

                GandCrab v2 Ransomware, were discovered in May 2018. With the new encryption extension of “.CRAB” and used more sophiscated domains as CnC.

                GandCrab v3 and v3.1 Ransomware were discovered in later 2018 with more antivirus evading techniques.

                GandCrab v4 Ransomware, brought many changes in the workflow and the endpoint communication patterns. The new extension “.KRAB” has been used and the creators have used new encryption algorithm. Surprisingly this variant, doesn’t connect a CnC.

                GandCrab v5 & v5.0.4 Ransomware brought many changes in the communication patterns and very advanced in the encryption standards. In later 2018, this created a greater impact and the increase of victims were huge.

What is CryptoMining Malware?

CryptoMining malware, or cryptocurrency mining malware or simply crypto jacking. Nowadays, Cyber criminals have increasingly turned to CryptoMining malware, as it’s a way to harness the processing power of large numbers of computers, smartphones and other electronic devices to help them generate revenue from cryptocurrency mining.

Therefore, they are infecting machines, utilize the device, encrypt using ransomware, destroy the traces and complete their actions. Cyber attackers are finding more ways in creating an alliance of various malware and combining them to achieve their goals.

 4.) Ensure your SOC team are monitoring for the traces of ransomware activity.

5.) Ensure your SOC team is monitoring for the abnormal activity of Powershell Executions.
