January 12, 2021

The SolarWinds attack leaves many unanswered questions and the most prominent amongst them is the question of how the attacker entered internal systems of SolarWinds network and was able to infiltrate and move inconspicuously across the development chain. The malware was able to camouflage its activity among the highly secure network of the prominent organization for an extended period of time, evading all their security detection and prevention defenses. In this particular blog, our team will mainly focus on the chain of events that occurred, and the evasive methods employed to remain completely stealthy despite moving around and compromising a highly secure network environment.

On December 13, 2020, FireEye reported a global campaign that targeted a large sector of industries by threat actors who inserted malicious code within a software component used by the popular network management software SolarWinds. It is not yet known how the threat actors managed to gain access to the development environment in which they added and distributed this malicious code as part of an update to the software. This trojanized version of the dynamic-link library (DLL) has been given the name ‘Sunburst’ by FireEye. Surprisingly enough, researchers have found evidence of the presence of a second backdoor in the SolarWinds product.

The National Security Agency published a list of 25 CVEs (Common Vulnerabilities and Exposures) that were most exploited by threat actors in recent times. Some of these CVE’s were used to deliver malicious software that allowed monitoring remote networks, maintaining continued access to remote networks, and, in some cases, using these CVEs to pivot to other systems within the internal network. For example, CVE-2019-11510 was used to gain access to sensitive VPN information of user accounts and then use the credentials to deliver ransomware like Sodinokibi. Similarly, CVE-2019-0803 was used to establish a backdoor to gain and maintain access to…

After several weeks of quiet, especially during the Christmas holidays, the Emotet malware bot is up and running again, and it seems stronger and smarter. Several IT security firms have reported seeing phishing emails delivering Emotet via malicious Word documents and even delayed holiday e-greetings. Cyber-attackers using Emotet seem to have used this brief hiatus to improve the malware’s social engineering abilities, with almost a fourth of infected emails being sent as replies to existing email threads. Designed initially as a banking malware, the Emotet Trojan was first identified by security researchers in 2014. The malware delivery botnet spreads itself…

Server Message Block or SMB is a protocol used extensively by windows. It allows windows computers to communicate, locate file servers, locate and communicate with windows networks services and even communicate with other operating systems that understand the SMB protocol. The latest version of SMB is SMB version 3 which is affected. Over the years numerous vulnerabilities were discovered in the protocol which were actively exploited and used by malware authors to build ransomware, cryptominers, SCADA malware etc. MS08-067 saw the rise of the Conficker worm, MS10-061 was used by the infamous Stuxnet malware and MS17-061 was used by ransomware’s…

Versa Security Lab recently analyzed couple of malware samples which arrives on a computer through phishing emails containing documents with embedded link which eventually leads to the download of the malware. Some of these may arrive through websites pretending to provide information on the recent Corona virus outbreak. The past few months have seen several malicious webservers and domains being set up, purportedly serving information on the Covid-19 virus outbreak. Most of these sites are hosts to ransomware and other malware types. In this blog we are going to look at one sample which encrypts files contents and updates the…

Universal Plug-n-Play – (UPnP) is a suite of protocols that enables a device to discover other devices on a network, configure itself to operate in the network, and advertise its services. This allows a device to locate routers, printers and other resources on a network. UPnP runs on UDP port 1900 and communicates using SOAP messages over HTTP. The actual configuration and management interface are implemented using a SOAP-based HTTP service running over a dynamically allocated TCP port. The UPnP protocol allows management of aspects of a device’s operation to extend support by the protocol implementation on the device and its…

The recent surge in cryptomining is providing cyber criminals with more vectors to attack, at the expense of legitimate users. This year has seen a huge increase in the deployment of numerous malwares, with cryptominers as primary or secondary payloads. Cryptominers are becoming easy targets, that allow attackers to go a step further to disguise themselves as the miner in the form of a flash update. Palo Alto Networks reported a list of collected samples, some dating back to August 2018[1]. The author further adds that installers from the Adobe website were legitimate, and the malicious ones were mostly Windows…

October 5, 2018

Lateral Movement Definition: Lateral movement is a technique used by cyber attackers to infiltrate and move through a network with the intent of obtaining secure data. The Cause The term “Lateral Movement” has been around for a little over four years and was in the news when ransomware like WannaCry and APT’s like APT28 and APT29 used lateral movement techniques.  Most often an attacker may not have direct access to a machine or resource on the internal network, which the attacker considers a prized trophy. The prized trophy may be the domain controller, a machine hosting confidential information, or the…
