Analysis of recent linux malware:

Today we received a linux malware sample for analysis.
MD5: 26413FD652A4ABB3FCA4A936DE6A4736

remnux@remnux:~/Downloads$ file ntpd
ntpd: ELF 32-bit MSB  executable, MIPS, MIPS-I version 1 (SYSV), statically linked, not stripped

This sample appears to be attacking bot. Let's look at the strings:

IOC details
  • hxxp://majestic12(.)co(.)uk/bot.php
  • hxxp://89.38.96(.)67/tftp
  • 89.38.96(.)67

Analysis of Brazilian Banker malware

Executive summary
Brazilian banker malware is one of the popular banking malware which targets South America and referred by malware researchers as SA-Banker or Brazilian Banker. Many campaigns were used by malware actors to reach the victim and lure them to give their credentials in the application. Once the fake application get the banking credentials which will be acquired by the malware authors. Last week, we got the attention of banking malware which uses campaigns using Facebook’s content delivery network (CDN).
Campaign using FB CDN:

Security researchers worried on the latest campaign using Facebook’s CDN so it makes harder for the security products to block.

Figure 1 CDN used in Brazilian banking malware
The last week data from malware hunter team says that around 200 thousand people opened the email from Brazil. Refer the following image from malware hunter team:

Figure 2 Email Infection stats

Our researchers dig deeper and get the malware samples for analysis. This is purely targeted on Brazil banking customers.
File MD5: 76E3E02AD689AF06699205D5BE956894
Size of the file: 752 KB

Figure 3 File submission

This sample was submitted to the system, two days back only and like we said the origin or source of the submission is Brazil. And the file type is dll.

Figure 4 Banker detection
We load the sample to PEid for checking the export details.
Figure 5 Export details of the malware sample
Further analysis will be published in the next post.

Locky download links for analysis (Pastebin link)

In our last postLocky Ransomware Latest Infection - Indicator of Compromise: ( we posted the details of IOC - indicator of compromise of famous Locky ransomware. Security researchers added few more details in the following pastebin link:

You can visit and get the links. But we copied those links as image.

Note: This is purely for research purpose and malware analysis purpose - Not for abusing this.

                                                                          Locky urls

IOC for latest locky ransomware infection:

Locky Infection URL:


Regex created for this php file is \/w\/[0-9a-z]{4}\.php.

Fake Dropbox landing page which serve locky ransomware:

Fake Dropbox link in the mail


Fake Dropbox landing page
It is advised to block these malicious url in the firewall, if you find any of these urls in your proxy logs or firewall that it is an indication of your system has been infected.

Linux/Tsunami Malware Captured from honeypot

Today we got a shell file which was captured from honeypot and submitted to VT. We checked the detection for that file and flagged as Linux/Tsunami.NJH. We directly look in to the contents of shell script and it is generic downloader as it seem.
Figure 1 Linux/Tsunami.NJH
 The script contains same IP address throughout the file: 46.218.149(.)85. We checked this IP address with those file directories in VT and it actually download malicious ELF file. We moved to the detection page and it got similar hits where Eset detects it as a variant of Linux/Tsunami.NCD. The family description for this variant says that it is a backdoor and can be controlled remotely. The main purpose of this malware is to download other malware files from the server, DDoS attack and shell command execution.

Downloaded files - analysis

Based on the details, we manually downloaded the important files and started our analysis. We started with the string analysis of these file to get any idea. All the three files which we downloaded have junk strings. And there is two line of strings which at least look like a Japanese words. Refer the below snapshot:

Figure 2 Strings of all the three files

·         0000000A5069   0000000A5069    nandemo shiranai wa yo,
·         0000000A5084   0000000A5084                    shitteru koto dake

String analysis – Based on Google search results

When we read that string it spell like Japanese words, we need to check in google. Yes it is Japanese word and it means “I don’t know anything” and “only I know”. But the plain google search leads to some interesting posts like funtime ninja codes and DDoS router malware.

Figure 3 Funtimes Ninja Malware

TFTP is a protocol for transferring data servers use to boot diskless workstations, X-terminals, and routers by using User Data Protocol (UDP). TFTP was primarily designed to read or write files by using a remote server. Here busybox is found in all the loops. It giving a hint that it could attack on limited resource linux machine (aka linux on embedded systems).

Let’s move on to the next one DDoS router malware article where we found the following yara rule to detect the presence of router DDoS malware:

import “elf”
rule STD
 author = “Akamai SIRT”
 description = “Kaiten/STD DDoS malware”
 $s0 = “shitteru koto dake”
 $s1 = “nandemo wa shiranai wa yo,”
 elf.number_of_sections == 0 and
 elf.number_of_segments == 2 and
 $s0 and $s1

This yara rule was created by researchers from Akamai for Kaiten/STD router DDoS malware.

Figure 4 DDoS Campaign
The above graph is from Akamai on the DDoS campaign from different locations across the globe.

Static analysis of the downloaded files

We ran the file command to check the file properties of these files, and resulted as valid elf file.

Figure 5 File command elf

Figure 6 ELF Header
When we try to disassemble these files we are facing following warnings:
·         Warning: read (shdr) at 0xffff
·         Warning: Cannot initialize section headers
·         Warning: Cannot initialize strings table

Using the initial script, tweaked few lines related to download, now it’s throwing error as exec format error.
Figure 7 Execution error

Based on the AV detection and string analysis, these files are found to be backdoor with DDoS functionalities. It is highly recommended to block the malicious IP address in the firewall and proxy. A good SOC with better threat intelligence feed will minimise the attack and even stop the attack before it creates any damage.
