JBS did not initially comment on whether it paid the attackers, and did not comment on its decision to close its North American plants for two days. The company was able to mitigate some of the damage of the attack using backups, but it was still forced to temporarily pause operations and suffer expensive downtime. JBS USA is the American subsidiary of JBS SA, a Brazil-based meat distribution firm. One month after Colonial Pipeline fell to hackers, the largest meat packing company in the world also suffered a debilitating attack. Mitigating the attack would be as simple as reaching into the malware and obtaining the decryption key it (still) contains. The malware would still contain its own copy of the data, which includes the decryption content. This would have interrupted the ransom process at its most critical moment. If Colonial Pipeline had deployed a data exfiltration solution, DarkSide’s malware would not have been able to exfiltrate its data to the C2 server. It exfiltrates this data to an attacker-specified C2 server before deleting its own copy and posting the ransom note.

It disables Windows services and targets terminated processes before recursively encrypting files until local and network shares are fully encrypted. Attackers infiltrated the network and sent a compressed malware executable into the system.ĭarkSide’s malware works by wiping the Recycle Bin and deleting volume copies using a non-restorable PowerShell script. Colonial Pipeline security professionals took the prudent action of taking down these systems before the attack spread, which contained the damage, but led to the sudden closure of a critical fuel pipeline, prompting a regional supply crunch that hurt consumers.ĭarkSide breached Colonial Pipeline’s systems using compromised account credentials from a legacy operational system that did not feature dual-factor authentication.
A Russia-based hacking group called DarkSide has claimed responsibility for the attack, which focused on SCADA systems that connect operational systems with traditional IT networks that are internet-connected.ĭarkSide successfully carried out their attack by focusing on Colonial Pipeline’s IT servers in its operational SCADA stack. The Colonial Pipeline attack is by far the most infamous of 2021 so far. Without this data, attackers could not have successfully launched their attack or proven access to sensitive data. Investigators determined that the attackers wanted to blackmail users with their sensitive data. It identifies sensitive data and then sends it outside the network before encrypting the data and launching the attack.ĭata exfiltration protection would have prevented Phoenix from copying, compressing, and sending data from the CNA environment to the hacker’s cloud account.
It tricks employees into installing the update, and then moves laterally throughout the network to gain higher privileges until it can successfully carry out phase two of the attack. The Phoenix ransomware executable works by posing as a browser update. It only revealed the specifics of the attack two months after paying the ransom, when it was obligated by law to do so. The group used a type of malware called Phoenix Locker, which is itself a variant of the more popular Hades ransomware executable.ĬNA Financials’ website remained closed for nearly two weeks after the attack. The company negotiated its ransom down from $60 million to $40 million, and paid for the decryption key that it needed to continue operations.Ī cybercrime syndicate called Phoenix claimed responsibility for the attack. The company announced the attack in late March 2021, stating that it had fallen victim to a sophisticated cyberattack.
Once inside, hackers are left effectively disarmed, unable to exfiltrate data or hide their tracks.ĬNA Financial is one of the largest insurance companies in the United States. This also prevents malware and ransomware applications from communicating with their command and control (C2) servers. It operates inside the network, preventing the unauthorized removal of data to external destinations. Anti data exfiltration (ADX) is a new technology that can protect against the sophisticated ransomware attacks that define today’s threat landscape.ĭata exfiltration protection is not a gateway solution. This underscores the fact that CISOs need to look beyond traditional best practices and start investing in a truly transformative approach to cybersecurity. Many of this year’s victims had endpoint security systems, gateway sandboxes, next-generation anti-virus solutions, and more – yet they still became victims nonetheless. Today’s cybersecurity solutions are not sufficient to prevent disruptive ransomware attacks. Looking at the year’s attacks, one thing is abundantly clear.
