The DHS issued an alert on ongoing attacks aimed at global managed service providers (MSPs) that are carried out by an advanced APT group.
Managed services is the practice of outsourcing on a proactive basis certain processes and functions intended to improve operations and cut expenses. It is an alternative to the break/fix or on-demand outsourcing model where the service provider performs on-demand services and bills the customer only for the work done.
The use of MSP is increasing the attack surface for attackers, the DHS’ alert TA18-276B, is related to activity that was uncovered by DHS’ National Cybersecurity and Communications Integration Center (NCCIC) in April 2017.
“The National Cybersecurity and Communications Integration Center (NCCIC) is aware of ongoing APT actor activity attempting to infiltrate the networks of global managed service providers (MSPs).” reads the alert issued by DHS.
“Since May 2016, APT actors have used various tactics, techniques, and procedures (TTPs) for the purposes of cyber espionage and intellectual property theft. APT actors have targeted victims in several U.S. critical infrastructure sectors, including Information Technology (IT), Energy, Healthcare and Public Health, Communications, and Critical Manufacturing.”
The group has been active at least since 2009, in April 2017 experts from PwC UK and BAE Systems uncovered a widespread hacking campaign, tracked as Operation Cloud Hopper, targeting managed service providers (MSPs) in multiple countries worldwide.
In July 2018, FireEye observed a series of new attacks of the group leveraging spear-phishing emails using weaponized Word documents that attempt to deliver the UPPERCUT backdoor, also tracked as ANEL.
The ANEL malware was already seen in the previous attack as a beta version or release candidate. In September, researchers from FireEye uncovered and blocked a campaign powered by the Chinese APT10 cyber espionage group aimed at Japanese media sector
DHS alert also provides technical information on detection, response and mitigation for this specific threat.
