DoppelPaymer Ransomware Sells Victims' Data on Darknet if Not Paid
February 3, 2020
https://www.bleepingcomputer.com/ne...re-sells-victims-data-on-darknet-if-not-paid/

The DoppelPaymer Ransomware is the latest family threatening to sell or publish a victim's stolen files if they do not pay a ransom demand.

This new tactic started in November 2019 when Maze Ransomware publicly released stolen files belonging to Allied Universal for not paying a ransom.
Since then, Sodinokibi/REvil published stolen data and the Nemty Ransomware announced in their RaaS affiliate panel that they would start doing it as well.

It is now DoppelPaymer's turn, who has told BleepingComputer that they have sold victim's data on the darknet in the past when they did not pay the ransom.

DoppelPaymer claims to sell victim's data
When looking at the DoppelPaymer Tor payment site, BleepingComputer noticed that they had recently started to tell victims that they have stolen their data and will to publish or sell it if a ransom is not paid.

In emails with the DoppelPaymer Ransomware operators, the threat actors told BleepingComputer that for almost a year they have been stealing data from their victims. They also claimed to have anonymously sold stolen files on the darknet in the past when a victim chose not to pay the ransom.
DoppelPaymer begins using a new extension
Recent versions of the DoppelPaymer ransomware have also switched to a new dedicated .doppeled extension for encrypted files.
BleepingComputer was told by the DoppelPaymer operators that this was done to make it easier for victims to know what ransomware encrypted their network.

Warning to law firms: a ransomware group is stealing data and posting it online
February 3, 2020
https://blog.emsisoft.com/en/35486/...group-is-stealing-data-and-posting-it-online/

Five law firms have been hit by a notorious ransomware group known as Maze – three within the last 72 hours alone. It is highly likely Maze will target more law firms in the days and weeks ahead. While only U.S. firms have so been hit, firms in other countries are equally at risk.
In staying true to Maze’s typical modus operandi, the cybergang didn’t simply encrypt the law firms’ data – they also stole it.

Maze initially names its victims and, if that is not sufficient to extract payment, publishes a small portion of their data online. This simply serves as proof that they have the data and is the equivalent of a kidnapper sending a pinky finger.
In regard to the recent attacks, Maze has already posted a portion of least two of the firms’ stolen data, which includes client information.

While Maze claims that the stolen data will be deleted upon payment, it would be a mistake to assume that that this will be done. Why would a criminal enterprise delete data that it may be able to further monetize?

Maze Ransomware Hackers Extorting Providers, Posting Stolen Health Data
February 4, 2020
https://healthitsecurity.com/news/m...xtorting-providers-posting-stolen-health-data

Recent reports have shown the hacking group behind Maze ransomware has been steadily posting the data of its victims online after the organizations fail to pay the ransom demand. A compiled list of victims shows the data of several healthcare organizations are included in those postings, despite a lack of public reporting of those incidents.

The FBI issued a warning in early January that the hackers behind Maze ransomware have increased targeted attacks on the private sector.
Beginning late last year, the Maze hackers began notifying sites like DataBreaches.net that it exfiltrated the data from its victims during the ransomware attacks and had been holding onto that sensitive information to later publish, if those organizations did not respond to their extortion demands.

In one of the most notable cases, Southwire, a cable and wire manufacturer out of Georgia, fell victim to Maze ransomware and refused to pay the $1.7M or 200 BTC demand. The hackers then went on to publish the stolen data [...]The site was taken down in less than 24 hours after the judge issued the order. However, Maze hackers registered two site domains and continued publishing the stolen data from Southwire.

One of the largest medical data postings appears to be from New Jersey’s Medical Diagnostics Laboratories (MD Lab).
When MD Lab refused to pay the extortion demand, the hackers went on to publish 9.5 GB of research data in an attempt to force negotiations with the provider.

About 29 companies are listed on the Maze website as organizations that have not paid the hackers. And the actors still have samples posted of the data they have claimed to have stolen.

Backing up is no panacea when blackmailers publish stolen data
Ransomware makers seem to be following a new trend, publishing data from companies that refuse to pay them
February 6, 2020
https://www.kaspersky.com/blog/ransomware-data-disclosure/32410/

Backing up data has been one of the most effective, though labor-intensive, safeguards against encrypting ransomware so far. Now, malefactors seem to have caught up with those who rely on backups. The creators of several ransomware programs, confronted with victims refusing to pay the ransom, shared their data online.
Maze was the first
Unlike its predecessors, the group behind Maze ransomware delivered on its promises in late 2019 — more than once. In November, when Allied Universal refused to pay up, the criminals leaked 700MB of internal data online including contracts, termination agreements, digital certificates, and more.
Next came Sodinokibi, Nemty, BitPyLock
Other cybercriminals followed. [...]

It is worrisome that there is no safeguarding oneself against these attacks with backups. If you are infected, there is no way for you to avoid losses, which will not necessarily be limited to ransom; blackmailers provide no guarantees. The only way to protect yourself is not to let malware into your systems.

Visser, a parts manufacturer for Tesla and SpaceX, confirms data breach
March 1,2020
https://techcrunch.com/2020/03/01/visser-breach/

A precision parts maker for space and defense contractors has confirmed a “cybersecurity incident,” which TechCrunch has learned was likely caused by ransomware.

Visser Precision, a Denver, Colorado-based manufacturer, makes custom parts for a number of industries, including automotive and aeronautics. In a brief statement, the company confirmed it was “the recent target of a criminal cybersecurity incident, including access to or theft of data.”
The company said it “continues its comprehensive investigation of the attack, and business is operating normally,” a spokesperson told TechCrunch.

Security researchers say the attack was caused by the DoppelPaymer ransomware, a new kind of file-encrypting malware which first exfiltrates the company’s data. The ransomware threatens to publish the stolen files if the ransom is not paid.

Brett Callow, a threat analyst at security firm Emsisoft, first alerted TechCrunch to the website that was publishing files stolen by the DoppelPaymer ransomware.

“Data theft is a strategy that multiple groups have now adopted and, consequently, ransomware incidents should be treated as data breaches until it can be established they are not,” said Callow.

Maze posts data allegedly stolen from PEI in ransomware attack

Brett Callow, a British Columbia-based threat analyst for Emsisoft who has seen the files, said they were posted over the weekend. That’s a week after PEI discovered and stopped a ransomware attack 90 minutes after it started.

In the PEI case the posted spreadsheets, PDFs, text and ZIP files are under a headline that reads”Proofs.” Callow says the files he’s seen include person’s names and social insurance numbers, copies of provincial bank statements, audits and budgets.
The public Maze site has listed a number of alleged successful ransomware attacks, but later some of their names have been erased. That suggests those organizations paid up, Callow said.

The Nemty Ransomware is the latest cybercrime operation to create a data leak site to punish victims who refuse to pay ransoms.

Once Maze Ransomware followed through with their threat and posted stolen files, other ransomware families such as DoppelPaymer and Sodinokibi started to launch leak sites to extort victims in a similar manner.
In a new site shared with BleepingComputer by Damien, the Nemty Ransomware operators have started to punish their non-paying victims by releasing files that were stolen before devices were encrypted.

As more ransomware operators begin to utilize this extortion tactic, victims will need to consider all ransomware attacks a data breach. This means file noticed with the government, alerting affected people, and sending out breach notifications.

A new ransomware called Nefilim that shares much of the same code as Nemty has started to become active in the wild and threatens to release stolen data.

Nefilim became active at the end of February 2020 and while it not known for sure how the ransomware is being distributed, it is most likely through exposed Remote Desktop Services.
Head of SentinelLabs Vitali Krimez and ID Ransomware's Michael Gillespie both told BleepingComputer that Nefilim and Nemty 2.5 share much of the same code.
Nefilim threatens to release data
In the Nefilim ransom note, the attackers state that if a user does not pay the ransom in seven days they will release data that was stolen from the network.

A large amount of your private files have been extracted and is kept in a secure location.
If you do not contact us in seven working days of the breach we will start leaking the data.
After you contact us we will provide you proof that your files have been extracted.

Unfortunately, a brief analysis by Gillespie indicates that this ransomware appears to be secure, which means that there is no current way to recover files for free.

Ransomware victims who do not pay a ransom and have their stolen files leaked are now facing a bigger nightmare as other hackers and criminals sell and distribute the released files on hacker forums.

Recently, the Sodinokibi Ransomware operators published over 12 GB of stolen data allegedly belonging to a company named Brooks International for not paying the ransom.
While making the data publicly accessible is bad enough, BleepingComputer has been told by cyber-intelligence firm Cyble that other hackers and criminals have started to distribute and sell this data on hacker forums.

From screenshots of the files shared with BleepingComputer, this stolen data is very valuable to hackers as it contains user names and passwords, credit card statements, alleged tax information, and much more.

Kimchuk, a medical and military electronics maker, has been hit by data-stealing ransomware, TechCrunch has learned.

Its systems were infected and knocked offline earlier this month by DoppelPaymer, a newer strain of ransomware that exfiltrates data out of an infected network before encrypting user files. If a victim doesn’t pay the ransom to decrypt their files, the DoppelPaymer group will begin publishing the contents of their victim’s network.
When the company did not pay, the hackers began publishing portions of Kimchuk’s network.

It isn’t known precisely when the ransomware attack happened. But a screenshot of a directory of stolen files seen by TechCrunch puts the most recent file at March 5, suggesting the attack happened on or around then.

EDP Group is one of the largest European operators in the energy sector (gas and electricity) and the world's 4th largest producer of wind energy.
Attackers threaten to leak 10 TB of stolen documents
During the attack, the Ragnar Locker ransomware operators claim to have stolen over 10 TB of sensitive company files and they are now threatening the company to leak all the stolen data unless the ransom is paid.

"We had downloaded more than 10TB of private information from EDP group servers," a new post on Ragnarok's leak site says.
Among the already leaked files published as a sign of what's to come, the attackers included an edpradmin2.kdb file which is a KeePass password manager database.

‘Double Extortion’ Ransomware Attacks Spike
More ransomware operators are setting up pages where they threaten to publish compromised data from victims
April 16, 2020
https://threatpost.com/double-extortion-ransomware-attacks-spike/154818/

Victims of ransomware attacks now face a double whammy of headaches. Cybercriminals are increasingly inflicting more pain on ransomware victims by threatening to leak compromised data or use it in future spam attacks, if ransom demands aren’t met.

The ransomware tactic, call “double extortion,” first emerged in late 2019 by Maze operators – but has been rapidly adopted over the past few months by various cybercriminals behind the Clop, DopplelPaymer and Sodinokibi ransomware families.

“Double Extortion is a clear and growing ransomware attack trend,” Lotem Finkelsteen, manager of threat intelligence with Check Point Research, said in a Thursday analysis. “We saw a lot of this in Q1 of 2020. In this tactic, threat actors corner their victims even further by dripping sensitive information into the darkest places in the web to substantiate their ransom demands.”
Click to expand...

A November 2019 ransomware attack against Allied Universal, a large American security staffing company, set the precedent for “double extortion.”
To prove the validity of the threat, the threat actors leaked 700 MB worth of data [...]

Now, researchers say that, TA2101, the group behind the Maze ransomware, have since created a dedicated web page which lists the identities of their non-cooperative victims and regularly publishes samples of the stolen data.

Research experts warn that “double extortion” attacks will continue to hit ransomware victims in 2020 [...]
“We’re especially worried about hospitals having to face this threat,” said researchers. “With their focus on coronavirus patients, addressing a double extortion ransomware attack would be very difficult. We issue caution to hospitals and large organization, surging them to back up their data and educate their staff.”

Maze Ransomware – What you Need to Know
April 23, 2020
https://www.tripwire.com/state-of-security/featured/maze-ransomware-what-you-need-to-know/

Maze is a particularly sophisticated strain of Windows ransomware that has hit companies and organisations around the world, demanding a cryptocurrency payment be made in return for the safe recovery of encrypted data.
But what makes Maze more dangerous is that it also steals the data it finds, exfiltrating it to servers controlled by malicious hackers who then threaten to release it if a ransom is not paid. Increasingly other ransomware (such as REvil, also known as Sodinokibi) has been observed using similar tactics.
HOW MUCH INFORMATION DOES THE MAZE RANSOMWARE TYPICALLY STEAL FROM A COMPANY?
It’s hard to say – as only the companies concerned and the criminals themselves will know how much has been taken. However, the Maze website has this to say:

“Usually we have over 100Gb of data from single client. Sometimes up to 10Tb of commercial and private information. We are looking for NDA marked information and everything that can be used as a base for the lawsuit agains our client.
WAIT. YOU MENTIONED THIS BEFORE. THE MAZE GUYS HAVE A WEBSITE?
The website includes details of when victims had their computer systems hit by the Maze ransomware, as well as links to downloads of stolen data and documents as “proof.”
There are even convenient buttons on the website to share details of breaches via social media.

Online leak undermines Torrance’s claim that no personal data was affected by cyberattack
April 22, 2020
https://www.scmagazine.com/home/sec...no-personal-data-was-affected-by-cyberattack/

BleepingComputer has reported that the attackers demanded a 100 ransom — which falls a bit short of $700,000 — after decrypting key files and exfiltrating breached data under the threat of publishing it.

In a March 1 press release set up on a temporary website, Torrance acknowledged the attack in generic terms, referring to an incident as a “digital compromise interrupting email accounts and server function,” resulting in the disruption of some city business services. Ransomware was not specifically cited as the cause.
In that statement, the city asserted that “Public personal data has not been impacted.” But if DoppelPaymer’s new post is, indeed, authentic, then this statement is wrong.

“I don’t know why governments make these hasty claims,” Callow told SC Media. “A more accurate statement would be, ‘We’ve been hit by a ransomware group which is known to steal data, but cannot yet say whether our data was stolen. [...]'”

However, Michael Smith, public information officer with Torrance, told SC Media that “Our initial press release still stands [on] its merits,” also noting that “there’s no update at this point.”
