“Proper investigation is in order and necessary to fully understand the impact and take remediation actions. Targets included rm, Linksys,, and US-based internet provider GoDaddy.Īvast researchers say they are still investigating the incident and have reached out to all affected companies. A range of Samsung domains resulted in five infections, while Singapore telco Singtel and US-based tech firms Intel and VMware all suffered one infection each.Īttackers were interested in a number of other targets, however they were not infected by the second payload. Japan-based nsl.as.nec.co.jp was also hit, resulting in 10 infected PCs. Out of the 40 PCs, Taiwan-based suffered the most, with 13 infected PCs. This, according to Avast researchers, is a ‘truly targeted attack'. However, because CCleaner backup database failed after the server ran out of disk space, attackers managed to back up data from the crashed server to another one before rebuilding the database, Avast researchers say.Īfter analysing the database, researchers found that there were more than 5.6 million connections to the C-C server, equating to more than 1.6 million unique PCs.Ĥ0 unique PCs received the second payload. The C-C server showed exactly what hosts it was communicating with through both the first and second payloads. Furthermore, given the clear lack of traffic on Saturdays and Sundays, it would indicate that it wasn't an Arabic country,” researchers state. “Given the typical working day starts at 8AM or 9AM, this leads us to the most likely location of the attacker in the time zone UTC + 4 or UTC + 5, leading us to Russia or the eastern part of Middle East / Central Asia and India. Researchers suspect the attack originated from China, because there were several code sequences to a previous APT attack known to have come from China.Īn analysis of the times and dates of C-C connections suggest that the attacker or attackers were operating from Asia. The attack has now been called an Advanced Persistent Threat (APT) attack due to the nature of its communications with its Command and Control (C-C) server. New research from Avast Threat Labs suggests that the recent CCleaner supply chain hack was actually part of a plan to go after some of the world's biggest companies, including many Asia Pacific firms.Īccording to the company's blog, the attack was never intended for consumers, but instead went after companies such as NEC, Samsung, Asus, Fujitsu, Sony, Singtel, Intel and VMware.
