LastPass says malware used to hack DevOps engineer in 2022 password vault breach

Password supervisor LastPass US LP reeled from a number of knowledge breaches in 2022 when hackers accessed delicate info from databases, and immediately the company revealed how attackers used that info to focus on a senior DevOps engineer with malware to “launch a coordinated second assault” that breached password vaults.

LastPass introduced the first security breach in August, saying the corporate detected uncommon exercise inside parts of the corporate’s improvement setting. The attacker gained entry to the corporate’s supply code and proprietary technical info.

On the time of the primary assault, the corporate mentioned that there was no proof that the incident concerned any buyer knowledge or encrypted password vaults.

Nonetheless, a second assault that happened in December did result in the attacker having access to encrypted passwords and encrypted backup knowledge and the corporate is now revealing the mechanics behind that assault. The corporate was fast to level out that the decryption keys weren’t stolen, so it could be tough, however not unimaginable, for the knowledge to be learn by an attacker.

“The risk actor leveraged info stolen in the course of the first incident, info accessible from a third-party knowledge breach, and a vulnerability in a third-party media software program bundle to launch a coordinated second assault,” the corporate mentioned.

Based on LastPass, its safety controls over its on-premises knowledge middle installations have been too strict for the attacker to beat, so it focused one of many 4 DevOps engineers who had entry to the cloud infrastructure.

The attacker managed to get malware onto the engineer’s residence laptop through a weak third-party media software program bundle and put in a bit of software program known as a keylogger. This allowed the attacker to observe each keystroke the engineer typed into the pc whereas working remotely and thus captured the login info and grasp password whereas interacting with the corporate’s cloud setting.

After having access to the corporate’s cloud utilizing the worker’s high-security entry, the attacker then stole vault entries and shared folders and encryption keys to the AWS S3 LastPass manufacturing backups and different cloud storage. That led to the attacker having access to encrypted knowledge vaults.

“That is an rising vector of refined cyberattacks: concentrating on sufferer’s staff, who’ve privileged entry to inner techniques, as a substitute attacking the victims instantly,” Dr. Ilia Kolochenko, founder and chief government of ImmuniWeb SA, which offers synthetic intelligence software safety, instructed SiliconANGLE.

Kolochenko defined that over the previous three years, a number of devastating supply-chain assaults have focused corporations, affecting their software program supply code and community protocols. Now, most organizations lock down their on-premises infrastructure and code extraordinarily tightly and consequently, attackers have begun to search for completely different chinks of their safety.

“Inventive cybercriminals have, nevertheless, found one other low-handing-fruit assault vector, a grim derivate of the pandemic and working-from-home development: the sufferer’s staff,” Kolochenko mentioned.

Firms corresponding to LastPass maintain extraordinarily essential assets corresponding to passwords, which in flip unlock even bigger potential treasures for hackers are particularly profitable targets for hackers.

These incidents aren’t the primary time the corporate has been hacked. In 2015, attackers broke into the corporate’s community, stole e mail addresses, password reminders and authentication hashes. Though on the time the corporate mentioned that grasp passwords weren’t stolen, it nonetheless urged customers to alter them.

Kolochenko believes that this yr cyber gangs will proceed to observe this development of concentrating on staff through the use of beforehand stolen info to focus on staff after which use their inner entry to realize additional traction into networks. Because of this, organizations ought to pay extra consideration to what sort of entry they’re offering to their staff and the kind of safety evaluate they’re doing.

“In 2023, we must always count on a surge of refined assaults on privileged tech staff aimed toward stealing their entry credentials and having access to the crown jewels,” Kolochenko mentioned. “Organizations ought to urgently contemplate reviewing their inner entry permissions and implement extra patterns to be monitored as anomalies, corresponding to extreme entry by a trusted worker or standard entry throughout nonbusiness hours.”
