Juniper Threat Labs discovered a new Trojan-delivered spyware that uses Telegram to exfiltrate stolen information. Using Telegram as a Command and Control (CnC) channel allows the malware some anonymity, as Telegram is a legitimate messaging application with 200 million monthly active users. The malware is being advertised on black market forums as “Masad Clipper and Stealer”. It steals browser data, which might contain usernames, passwords and credit card information. Masad Stealer also automatically replaces cryptocurrency wallets from the clipboard with its own.
On August 7, 2019, Juniper Threat Labs started seeing attacks on PHP-FPM (FastCGI Process Manager) on port 9000. This attack works by passing PHP configuration options that allows injection of a PHP script to a listening PHP-FPM service. The attack payload is a base64 encoded PHP script that collects system information, presumably as part of a reconnaissance stage.
I recently had the pleasure of participating in a panel discussion at the Cyber Security Summit USA in Denver, CO, on the topic of cloud INsecurity. The panel needed to cover the common pitfalls that organizations make when moving to the cloud and how to avoid them. Joined by several distinguished panelists from the security industry, we tackled some key questions and I wanted to share the key takeaways with those who were not so fortunate to join us live during the event.
Juniper Threat Labs has been monitoring a campaign that delivered multiple stages of malware to install a cryptocurrency miner and ransomware. On March 16, 2019, we identified a surge in attacks that target an Apache Struts vulnerability to deliver their payload.
Juniper Threat Labs recently discovered an attack campaign that installs a cryptominer and also spreads on the network. This campaign is interesting as one of its technique is using the infamous EternalBlue exploit and DoublePulsar backdoor.
The attack campaign starts with an HTTP request that attempts to exploit several vulnerabilities of Web Application servers. Recently, this group has been active as they have added the ThinkPHP exploit to their arsenal. This exploit was seen to be used for other campaigns as well as seen by an earlier Alibaba threat report. The following section will detail the exploits and malware the threat actors are using for this campaign.
Juniper Threat Labswas recently investigating and analyzing the resurgence of Troldesh ransomware and during our investigation, we gained a few insights into their operation. What we found is that the threat actors implemented a coordinated operation by using other modules to distribute their malware. They use a CMS bruteforcer module that is responsible for infecting loosely configured CMS sites that are used as download servers. They monetized their operation via ransomware and cryptomining. They also use TOR for all of their network communication to give them anonymity.
