Attackers accessed a VPN account that was no longer in use to freeze the company’s network in a ransomware attack whose repercussions are however vibrating.
It took only 1 dusty, no-lengthier-utilized password for the DarkSide cybercriminals to breach the network of Colonial Pipeline Co. past thirty day period, resulting in a ransomware attack that brought on sizeable disruption and continues to be less than investigation by the U.S. govt and cybersecurity authorities.
Attackers made use of the password to a VPN account that was no for a longer period in use but continue to allowed them to remotely accessibility Colonial Pipeline’s network, Charles Carmakal, senior vice president at FireEye’s cybersecurity consulting company Mandiant, told Bloomberg in an job interview, in accordance to a revealed report on the information outlet’s site.
The news the moment all over again highlights the worth of password security, as it comes on the heels of a different report that hackers leaked the major password selection to day – a 100 gigabyte file identified as “RockYou2021” made up of 8.4 billion passwords – on a common hacker forum previously this week.

“We really do not see any evidence of phishing for the personnel whose credentials ended up utilized,” Carmakal instructed Bloomberg. “We have not seen any other evidence of attacker action ahead of April 29.”
He speculated that perhaps the password may possibly have gotten into the incorrect fingers when a Colonial staff utilized it on one more account that was previously hacked, according to the report.
The news once again highlights the inherent insecurity of what is still the most frequently used security process for enabling workers to entry corporate networks, even while there are numerous multi-factor authentication and id-management procedures obtainable to organizations for securing delicate data.
It also exhibits how easy it is for any person with nefarious intent to obtain obtain to someone’s password and use it for economical gain or disruption, with huge caches of passwords lifted from cyberattacks continually remaining dumped on the internet by hackers, observed just one security specialist.
“The bar is now ridiculously low for attackers to come into get in touch with with such massive sums of knowledge, just about undetected,” Mike Puglia, chief system officer at unified IT administration program company Kaseya, said in an email to Threatpost. “It necessitates small technological potential, and the fiscal value to carry attacks out is negligible.”
Buying credential lists and attack kits can be completed by “anyone” and produce .2 p.c .5 percet achievement charges on targets that comprise “a modest variety of environments that anyone uses,” he explained.
“As lengthy as the achievement rates remain significant and the expense and work stays very low, these attacks will continue on to increase,” Puglia reported.
Colonial Pipeline, which serves the jap U.S., to start with described that it was the target of a ransomware attack on May 7. The attack shut down a pipeline that covers the full jap seaboard as much north as New York as perfectly as southern states and prompted key disruption, including fuel shortages throughout the location, a sharp increase in fuel prices and airlines scrambling for fuel.
The attack’s results were so dire that President Joe Biden declared a state of emergency, and Colonial Pipeline finished up paying out the ransom – about $4.4 million in Bitcoin – to the DarkSide ransomware gang for a decryption tool so it could restore techniques disabled in the attack.
In fact, economical obtain was always the inspiration for the attack, with DarkSide publicly stating in the times pursuing the incident that the disruption it induced was mere collateral problems and not the group’s primary intent.
The FBI and Section of Justice managed to track Colonial Pipeline’s ransom payment as a result of a selection of cryptocurrency wallets managed by DarkSide and have now clawed back about $2.3 million value of bitcoin from the ransomware-as-a-assistance (RaaS) gang’s electronic wallet, they mentioned before this week.
