Hackers claim to have stolen confidential files belonging to the Jones Day law firm, which once represented former-president Donald Trump. The hackers allegedly posted sensitive files on the dark web, but the law firm denies the breach occurred.
DataBreaches.net initially reported the attack, which is thought to involve the Clop ransomware gang. The hackers claimed to have obtained 100GB of data from the law firm and published redacted files to prove their attack. The gang has demanded a $20 million ransom payment in return for a decryption key.
The law firm disputed the hackers' claims that they breached its network. However, it did say a file-transfer platform it used was recently compromised, affecting the firm’s data. The compromised platform belongs to California-based cloud computing company Accellion.
“Jones Day has been informed that Accellion’s FTA file transfer platform, which is a platform that Jones Day—like many law firms, companies, and organizations—used was recently compromised and information taken,” a spokesperson for the firm said in a statement to Bloomberg Law.
“Jones Day continues to investigate the breach and has been, and will continue to be, in discussion with affected clients and appropriate authorities.”
The Wall Street Journal said it’s not only seen some breached files, but it could also “see the existence of many more files — mammoth in size — also purported to belong to Jones Day.”
James McQuiggan, Security Awareness Advocate at KnowBe4, told IT Pro that like the SolarWinds supply-chain attack, the cyber criminals are focusing their attacks on those third parties and service providers that support many customers.
“These organizations will want to review and elevate their security programs to ensure they do not suffer a breach, leading to a similar compromise. These attacks damage the organization’s customers and clients and damage the reputation and possible bottom line for that organization,” McQuiggan said.
“With an organization that provides large file transfers, one consideration for them to protect their data is to encrypt the data before transferring it and to protect it from the third-party provider. Upon delivery to the receiver, they would have the key to decrypt and view the data."
Martin Jartelius, CSO at Outpost24, told IT Pro what we’re seeing now are the effects of the Accellion intrusion from December.
“It’s an external file sharing solution that’s decades-old and has been used by several organizations. As we are seeing more and more data related to the breach hitting the news, other organizations that have used the services should review and prepare processes to inform any clients and any individuals for whom data has been processed on this platform,” Jartelius said.
“Noting that we are approaching a two-month mark from when the breach likely occurred, those who suspect they may be affected should consider informing any affected data subjects at the soonest in line with current privacy legislation and not wait and hope for the best.”
