Denso confirmed that cybercriminals leaked stolen, categorized information and facts from the Japan-dependent car-parts company soon after an attack on 1 of its workplaces in Germany.
A multibillion supplier to important automotive corporations like Toyota, Mercedes-Benz and Ford verified Monday that it was the target of a cyberattack over the weekend – affirmation that came immediately after the Pandora ransomware group started leaking data that attackers claimed was stolen in the incident.
The attack on Japan-based Denso occurred at a company place of work in Germany, which was “illegally accessed by a third occasion on March 10,” the company stated in a press assertion on its web-site.
“After … detecting the unauthorized obtain, Denso instantly reduce off the network link of gadgets that been given unauthorized entry and confirmed that there is no impression on other Denso facilities,” the corporation said in the statement.
Denso is a person of the world’s major suppliers of automotive components – which include powertrain regulate and electronics components – to best vehicle makes these kinds of as Toyota, Mercedes-Benz, Ford, Honda, Volvo, Fiat and Typical Motors. The Japan-primarily based supplier noted $44.6 billion in profits last yr and has additional than 200 subsidiaries with 168,391 workforce around the globe.
Denso is at the moment investigating the incident with appropriate authorities and creation carries on at “all plants as usual,” in accordance to the assertion.
Toyota Facts Leaked
On the other hand, categorised info from Toyota stolen in the attack on Denso currently has been leaked on the dark web by Pandora, in accordance to Japanese security firm Mitsui Bussan Safe Directions.
The corporation advised Japanese news outlet NHK that Pandora posted a concept on the dark web on Sunday afternoon, Japan time, professing to have stolen far more than 157,000 merchandise amounting to 1.4 terabytes of data belonging to the Toyota Motor group. This is the 2nd time in a couple months that Toyota has been strike: In late February, the auto maker was compelled to shut down its Japan plants after a suspected cyberattack.
On Saturday, Japanese time, the dark-web felony intelligence business DarkTracer tweeted a screenshot of the Denso listing on Pandora’s leak portal. Studies explained that the dump incorporates acquire orders, e-mails, non-disclosure agreements, technological drawings and other categorised facts.

It’s unclear at this time if Pandora managed to encrypt files ahead of the most new attack was detected, nor how a lot, if any, ransom is getting demanded, in accordance to stories. The a single-two punch of equally encrypting data files and then threatening to leak or really leaking documents is a acknowledged ransomware tactic dubbed “double extortion.”
Offer-Chain Under Attack
The Denso attack is the second provide-chain cyber incident that has impacted Toyota this yr. In February, an attack on Toyota supplier Kojima Industries Corp. pressured the company to shut down its Japanese plants.
These incidents show the threat of assaults to the provide chain of multinational organizations, stressing the want to maintain and regulate the exact same security at the principal company throughout all partners and small business units, one security experienced reported.
“Cybercriminals will generally exploit the weakest hyperlink, and in today’s interconnected networks can do sizeable injury from compromising even a smaller small business unit,” Chris Clements, vice president of remedies architecture at security business Cerberus Sentinel, wrote in an email to Threatpost on Monday. “It’s no extended more than enough for organizations to only aim on their means to stop or get well from a ransomware attack as attackers now routinely steal mass quantities of details as component of their functions.”
Indeed, the knowledge theft included in double-extortion assaults can be even extra unsafe than simply just a classic encryption-based mostly ransomware attack due to the unpredictability of attackers at the time they get their arms on sensitive and proprietary info, he mentioned.
“There is no way to verify that the attacker will really delete the facts instead of trying to resell it on the dark web or simply just release it publicly,” Clements reported.
Rising Ransomware Menace
The Pandora group is comparatively new on the ransomware scene, emerging earlier this month as a new player in the danger landscape that makes use of this unsafe process of double extortion to blackmail targets.
Pandora’s designers have made the ransomware to encrypt sensitive documents to prohibit access by appending the .pandora extension to filenames to protect against victims from opening impacted files, in accordance to investigate from Malware Warrior.
Considering the fact that Pandora is this kind of a new risk, it’s not yet regarded how cybercriminals breach company networks to infect programs with the ransomware. On the other hand, clues may be identified in formerly energetic ransomware teams and their procedures, researchers reported.
A single security researcher with the Twitter deal with pancak3 believes Pandora is a re-branding of Rook ransomware, which in transform borrows code from Babuk ransomware. That now-defunct ransomware-as-a-support (RaaS) group – which is most likely marketing its products and services for other cybercriminals to use – also utilized double extortion in its attacks in the course of its heyday.
