Chinese-linked APTs have been linked to a recent RA World ransomware attack that used tools previously associated with espionage actors. The attackers demanded $2 million in ransom, reduced to $1 million if paid within three days.
The RA World ransomware attack was carried out by an independent actor linked to China-based Advanced Persistent Threat (APT) groups. The attackers exploited a Palo Alto PAN-OS vulnerability and used a toolset previously associated with China-linked espionage actors. The attack utilized ransomware and PlugX malware, with encryption keys similar to those used by Fireant, a China-based espionage group. The attackers demanded a $2 million ransom, reduced to $1 million if paid within three days. The incident suggests the threat actor may be using ransomware as a diversionary tactic while maintaining persistent access to the victim's systems. The attackers' use of proxy tools and encryption keys indicates a high level of sophistication.
In recent months, cybersecurity experts have been abuzz with the latest development in the world of cyber threats. A new actor has emerged, one that is linked to China-based Advanced Persistent Threat (APT) groups, but operates independently as a ransomware operator. This threat actor, identified by researchers at Broadcom, has been linked to a recent attack on an Asian software firm using a tool previously associated with China-linked espionage actors.
The RA World ransomware attack, which took place in late 2024, was notable for its use of a distinct toolset that had previously been used by a China-linked APT group. The attackers exploited a Palo Alto PAN-OS vulnerability (CVE-2024-0012) to gain access to the victim's systems, stole data from Amazon S3, and then deployed RA World ransomware. The attack also utilized a Toshiba executable to sideload PlugX malware, which is identical in compilation timestamps to the Thor PlugX variant tied to Fireant (aka Mustang Panda, Earth Preta), a China-based espionage group.
The use of this toolset by an independent actor suggests that the threat actor may not be affiliated with any known Chinese APT group. However, the similarity in the configuration structure and encryption key used by both variants reinforces their connection to the espionage group. The attackers also demanded a $2 million ransom from the victim, reduced to $1 million if paid within three days.
The circumstances of the attack suggest that the threat actor may be attempting to use ransomware as a means of extorting money while maintaining persistent access to the victim's systems. This is a common tactic employed by APT groups, who often use ransomware as a diversionary tactic to hide their true intentions.
Researchers at Broadcom have pointed out that tools belonging to China-linked APT groups are often shared resources, but many aren't publicly available and aren't usually associated with cybercrime activity. The fact that the attackers used a toolset previously associated with espionage actors suggests that they may be trying to maintain plausible deniability about their true intentions.
The RA World ransomware attack is also notable for its use of a proxy tool called NPS, which was previously used by Bronze Starlight (aka Emperor Dragonfly), a China-based group deploying various ransomware. SentinelOne has linked Bronze Starlight to other ransomware variants such as LockFile, AtomSilo, and NightSky.
The attackers may have prior ransomware involvement, according to evidence suggesting that Palo Alto linked the RA World attacks to Bronze Starlight. This suggests that the threat actor may not be a new player in the world of ransomware, but rather someone who has experience with this type of attack.
Another possibility is that the nation-state actor used the ransomware attack as a cover-up or diversion, but it failed to hide espionage tools and targeted an atypical organization. The attacker also actively pursued ransom negotiations, which is uncommon for mere deception.
The most likely scenario is that an actor, possibly one individual, was attempting to make some money on the side using their employer's toolkit. This theory is supported by the fact that the attackers demanded a large ransom, reduced to $1 million if paid within three days.
In conclusion, the recent RA World ransomware attack highlights the evolving nature of cyber threats in 2024. China-linked APTs are becoming increasingly sophisticated, and it's clear that independent actors are also taking note of these tactics. The use of proxy tools, encryption keys, and ransom demands all suggest a level of sophistication that is unmatched by most traditional malware.
As researchers continue to unravel the mysteries of this attack, one thing is clear: the world of cyber threats has become increasingly complex, and it's up to security experts to stay vigilant and adapt to new tactics.
