Quote:Czech antivirus vendor Avast on Monday warned that hackers were able to access its internal network using a temporary VPN account.
 
Avast said that it believes that the intrusion, first detected on Sept. 25, was likely targeting its CCleaner business in a supply chain attack. CCleaner, which is software that fights infections in PCs, was previously infiltrated by attackers in 2017 and led to the compromise of 2.27 million people’s systems.
 
“From the insights we have gathered so far, it is clear that this was an extremely sophisticated attempt against us that had the intention to leave no traces of the intruder or their purpose, and that the actor was progressing with exceptional caution in order to not be detected,” said Jaya Baloo, chief information security officer with Avast in a post on Monday. “We do not know if this was the same actor as before and it is likely we will never know for sure, so we have named this attempt ‘Abiss’.”
