Verisource Services, an employee benefits administration service provider, has determined that a previously announced data breach was far worse than initially thought and has affected up to 4 million individuals. The Houston, Texas-based company detected a hacking incident on February 28, 2024, that disrupted access to some of its systems. Third-party cybersecurity and incident response experts were engaged to investigate the incident and determine the nature and scope of the unauthorized activity.
The forensic investigation confirmed hackers had access to its network and exfiltrated files on February 27, 2024. At the time of the initial announcement, Verisource Services said names, dates of birth, genders, and Social Security numbers had been stolen. The affected individuals included employees and dependents of clients who used its services, which include HR outsourcing, benefits enrollment, billing, and administrative services.
The data breach was initially reported as affecting 1,382 individuals, but as the investigation progressed, it became clear that the breach was worse than initially thought. In August 2024, the data breach was reported to the HHS’ Office for Civil Rights (OCR) as involving the protected health information of 112,726 individuals. The most recent notification to the Maine Attorney General indicates up to 4 million individuals have been affected, a sizeable increase from previous estimates. The OCR breach portal still lists the incident as affecting 112,726 patients and plan members of its HIPAA-regulated entity clients, although that total may well be updated in the coming days.
Verisource Services explained in the breach notice that the data review was not completed until April 17, 2025, almost 14 months after the security incident was detected. Verisource Services reported the security incident to the Federal Bureau of Investigation, and several additional security measures have been implemented to improve its security posture. Notification letters had previously been sent to some affected individuals; however, the bulk of the notification letters have only recently been mailed. Verisource Services said complimentary credit monitoring and identity theft protection services have been offered to the affected individuals, who will also be protected with a $1,000,000 identity theft insurance policy.
Hitachi Vantara, a subsidiary of Japanese multinational conglomerate Hitachi, was forced to take servers offline over the weekend to contain an Akira ransomware attack.
The company provides data storage, infrastructure systems, cloud management, and ransomware recovery services to government entities and some of the world's biggest brands, including BMW, Telefónica, T-Mobile, and China Telecom.
In a statement shared with BleepingComputer, Hitachi Vantara confirmed the ransomware attack, saying it hired external cybersecurity experts to investigate the incident's impact and is now working on getting all affected systems online.
"On April 26, 2025, Hitachi Vantara experienced a ransomware incident that has resulted in a disruption to some of our systems," Hitachi Vantara told BleepingComputer.
"Upon detecting suspicious activity, we immediately launched our incident response protocols and engaged third-party subject matter experts to support our investigation and remediation process. Additionally, we proactively took our servers offline in order to contain the incident.
"We are working as quickly as possible with our third-party subject matter experts to remediate this incident, continue to support our customers, and bring our systems back online in a secure manner. We thank our customers and partners for their patience and flexibility during this time."
Following news of cyber incidents impacting UK retailers, the NCSC can confirm it is working with organisations affected.
NCSC CEO Dr Richard Horne said:
“The disruption caused by the recent incidents impacting the retail sector are naturally a cause for concern to those businesses affected, their customers and the public.
“The NCSC continues to work closely with organisations that have reported incidents to us to fully understand the nature of these attacks and to provide expert advice to the wider sector based on the threat picture.
“These incidents should act as a wake-up call to all organisations. I urge leaders to follow the advice on the NCSC website to ensure they have appropriate measures in place to help prevent attacks and respond and recover effectively.”

HALIFAX, Nova Scotia--(BUSINESS WIRE)-- Emera Inc. and Nova Scotia Power today announced, on April 25, 2025 they discovered and are actively responding to a cybersecurity incident involving unauthorized access into certain parts of its Canadian network and servers supporting portions of its business applications.
Immediately following detection of the external threat, the companies activated their incident response and business continuity protocols, engaged leading third-party cybersecurity experts, and took actions to contain and isolate the affected servers and prevent further intrusion. Law enforcement officials have been notified.
There remains no disruption to any of our Canadian physical operations including at Nova Scotia Power’s generation, transmission and distribution facilities, the Maritime Link or the Brunswick Pipeline, and the incident has not impacted the utility’s ability to safely and reliably serve customers in Nova Scotia. There has been no impact to Emera’s U.S. or Caribbean utilities.
Emera will release its Q1 Financial Statements and Management Disclosure and Analysis on May 8, 2025, as planned. At this time, the incident is not expected to have a material impact on the financial performance of the business.
Our IT team is working diligently with cyber security experts to bring the affected portions of our IT system back online.
The individuals operating under the DragonForce banner and attacking UK high street retailers are using social engineering for entry. I think it’s in the public interest to break down what is happening.
The attacks on Marks and Spencer, Co-op and Harrods are linked. DragonForce’s lovely PR team claim more are to come.
Defenders should urgently make sure they have read the CISA briefs on Scattered Spider and LAPSUS$ as it’s a repeat of the 2022–2023 activity which saw breaches at Nvidia, Samsung, Rockstar and Microsoft amongst many others. More info below.
I am not saying it is Scatter Spider; Scattered Spider has become a dumping ground for e-crime groups anyway. The point is they — the threat actor — are entering using the front door, via the helpdesk to get MFA access — those are very good guides from defenders about what to do, links below.

DragonForce is a white label cartel operation housing anybody who wants to do e-crime. Some of them are pretty good at e-crime.
While organisations are away at RSA thinking about quantum AI cyber mega threats — the harsh reality is most organisations do not have the foundations in place to do be worrying about those kind of things. Generative AI is porn for execs and growth investment — threat actors are very aware that now is the time to launch attacks, not with GenAI, but foundational issues. Because nobody is paying attention.
Once they get access, they are living off the land — using Teams, Office search to find documentation, the works. Forget APTs, now you have the real threat: Advanced Persistent Teenagers, who have realised the way to evade most large cyber programmes is to cosplay as employees. Last time this happened, the MET Police ended up arresting a few under-18 UK nationals causing incidents to largely drop off.
The uptick began in the fourth quarter of 2024 and continued into 2025, with the increases largely attributed to Clop’s exploitation of a popular file sharing service.
Jonathan Braley, director of cyber information sharing organization Food and Ag-ISAC, spoke at the RSA Conference on Thursday and warned of not only the increase in ransomware incidents but the continued lack of visibility into the full scope of the problem.
“A lot of it never gets reported, so a ransomware attack happens and we never get the full details,” he told Recorded Future News on the sidelines of the conference. “I wish companies would be more open in talking about it and sharing ‘Here's what they use, here's how we fixed it,’ so the rest of us can prevent that.”
The uptick began in the fourth quarter of 2024 and continued into 2025, with the increases largely attributed to Clop’s exploitation of a popular file sharing service. But Braley noted that even when they took out the attacks attributed to Clop, groups like RansomHub and Akira were still continuing to attack the food industry relentlessly.
The Food and Ag-ISAC obtained its numbers through a combination of open-source sites, dark web monitoring, member input and information sharing between National Council of ISAC members.
The industry saw 31 attacks in January and 35 in February before a dip to 18 attacks in March.
The 84 attacks seen from January to March were more than double the number seen in Q1 2024.
Another day, another edge device being targeted - it’s a typical Thursday!
In today’s blog post, we’re excited to share our previously private analysis of the now exploited in-the-wild N-day vulnerabilities affecting SonicWall’s SMA100 appliance. Over the last few months, our client base has fed us rumours of in-the-wild exploitation of SonicWall systems, and thus, this topic has had our attention for a while.
Specifically, today, we’re going to be analyzing and reproducing:
CVE-2024-38475 - Apache HTTP Pre-Authentication Arbitrary File Read
Discovered by Orange Tsai
Although this is a CVE attached to the Apache HTTP Server, it is important to note that due to how CVEs are now assigned, a seperate CVE will not be assigned for SonicWall's usage of the vulnerable version.
This makes the situation confusing for those responding to CISA's KEV listing - CISA is referring to the two vulnerabilities in combination being used to attack SonicWall devices.
You can see this evidenced in SonicWall's updated PSIRT advisory: https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2024-0018
CVE-2023-44221 - Post-Authentication Command Injection
Discovered by "Wenjie Zhong (H4lo) Webin lab of DBappSecurity Co., Ltd”
As of the day this research was published, CISA had added these vulnerabilities to the Known Exploited Vulnerabilities list.
Do you know the fun things about these posts? We can copy text from previous posts about edge devices:
Luxury department store is forced to shut some systems but website and shops continue to operate.
Harrods has been hit by a cyber-attack, just days after Marks & Spencer and the Co-op were targeted.
The luxury department store is understood to have been forced to shut down some systems, but said its website and all its stores, including the Knightsbridge flagship, H beauty and airport outlets, continued to operate. It is understood the retailer first realised it was being targeted earlier this week.
Harrods said in a statement: “We recently experienced attempts to gain unauthorised access to some of our systems. Our seasoned IT security team immediately took proactive steps to keep systems safe and as a result we have restricted internet access at our sites today.”
The retailer said it was not asking customers to take any action, indicating that it did not suspect data had been accessed. It added: “We will continue to provide updates as necessary.”
Recent Western government revelations about EvilCorp flesh out how Russian ransomware actors and the Russian government use each other to navigate a world they perceive as dangerous.
Note added April 30 2025:
Originally posted October 16, 2024 in a very different global geopolitical context, this analysis remains relevant today. Subsequent revelations, especially a set of leaked messages from the Black Basta group – a successor to the Conti group – reaffirm the complexity of relations between Russian ransomware actors and security officials. (The Natto Team discussed the value of leaks here). The Black Basta leaks show that group's members as:
Receiving Protection: Black Basta chief “Tramp” – who chose as his moniker the Russian version of the current US president’s name – boasted of receiving high-level help from Russian authorities after Armenian officials arrested him in June 2024.
But Still Vulnerable: Tramp speculated in July 2024 that someone from their circle had snitched on him, “tempted” by the rewards the US State Department has offered for information on Tramp. He also received tipoffs from criminal acquaintances and from “my law enforcement people,” telling him that Russian officials faced international pressure to crack down on Russian cybercriminals: “those who get paid by Interpol here will start making our lives hell.” In September 2024, Black Basta coder “YY” told Tramp that Russian officials had raided YY's home, impounded his car, and “marinated” him in custody for a time.
Under Pressure to Work for the Russian State: In a November 14 2022 chat, “Tramp” said, “I have guys in Lubyanka [FSB headquarters] and the GRU [military intelligence agency] – I have been “feeding” them for a long time. They only want to take people on to work for them. They won’t even talk about [prison] sentences or anything. You can go in to work every day at 8 am and leave at 6 pm, just like in a ‘white’ [legitimate] job.”
Tracking Geopolitics: In May 2024, after Black Basta paralyzed IT systems at US-based Ascension Healthcare, Black Basta ransom negotiator “Tinker” pondered the group's extortion strategy in light of US election-year politics. He mused that, if anyone died as a result of the group’s attack on a healthcare entity – particularly a Christian hospital system like Ascension – US citizens would demand that their government do whatever it took to induce Russia to crack down on the criminals. Tinker speculated that the Joe Biden administration might make serious concessions to Russia, such as reducing military aid to Ukraine, in return for Russia’s cracking down on the criminals. For the Natto Team’s own assessment of Russian-US “ransomware diplomacy,” see here and here.
It will be interesting to observe how Russian cybercriminals interpret recent developments in US-Russian relations.
Bitdefender researchers have uncovered a surge in subscription scams, both in scale and sophistication, spurred by a massive campaign involving hundreds of fraudulent websites.
Ledger has warned that scammers are mailing letters that appear to be from the company to users of its hardware wallets in an attempt to swipe crypto.
Scammers are mailing physical letters to the owners of Ledger crypto hardware wallets asking them to validate their private seed phrases in a bid to access the wallets to clean them out.
In an April 29 X post, tech commentator Jacob Canfield shared a scam letter sent to his home via post that appeared to be from Ledger claiming he needed to immediately perform a “critical security update” on his device.
The letter, which uses Ledger’s logo, business address, and a reference number to feign legitimacy, asks to scan a QR code and enter the wallet’s private recovery phrase under the guise of validating the device.
Cell C, South Africa’s fourth largest mobile network operator, said on Wednesday morning that RansomHouse had unlawfully disclosed data after a security breach for which RansomHouse is claiming responsibility.
The operator, with 7.7 million subscribers as of February, was attacked in early November 2024 and RansomHouse acquired 2TB of data, which has been corroborated by files posted on the dark web, according to security company PFortner.
Data accessed included:
Full names and contact details (email, phone numbers)
ID numbers
Banking details (if stored for billing purposes)
Driver’s License Numbers
Medical Records (if supplied for closure of accounts on death of a family member)
Passport details
It is not clear how many people were affected.
On April 26, an unauthorized user exploited a vulnerability with a GitHub workflow to gain unauthorized access to tokens, all of which have now been invalidated. At this time, our investigation has found no evidence of code modifications, unauthorized access to production systems, exposure of customer data, or access to personal information.
Socket’s Threat Research Team uncovered malicious Python packages designed to create a tunnel via Gmail. The threat actor’s email is the only potential clue as to their motivation, but once the tunnel is created, the threat actor can exfiltrate data or execute commands that we may not know about through these packages. These seven packages:
Coffin-Codes-Pro
Coffin-Codes-NET2
Coffin-Codes-NET
Coffin-Codes-2022
Coffin2022
Coffin-Grave
cfc-bsb
use Gmail, making these attempts less likely to be flagged by firewalls and endpoint detection systems since SMTP is commonly treated as legitimate traffic.
These packages have since been removed from the Python Package Index (PyPI).
Researchers say the behavior amounts to a persistent backdoor.
rom the department of head scratches comes this counterintuitive news: Microsoft says it has no plans to change a remote login protocol in Windows that allows people to log in to machines using passwords that have been revoked.
Password changes are among the first steps people should take in the event that a password has been leaked or an account has been compromised. People expect that once they've taken this step, none of the devices that relied on the password can be accessed.
The Remote Desktop Protocol—the proprietary mechanism built into Windows for allowing a remote user to log in to and control a machine as if they were directly in front of it—however, will in many cases continue trusting a password even after a user has changed it. Microsoft says the behavior is a design decision to ensure users never get locked out.
Independent security researcher Daniel Wade reported the behavior earlier this month to the Microsoft Security Response Center. In the report, he provided step-by-step instructions for reproducing the behavior. He went on to warn that the design defies nearly universal expectations that once a password has been changed, it can no longer give access to any devices or accounts associated with it.

Malware Analysis Report - LockBit Ransomware v4.0
In this blog post, I’m going over my analysis for the latest variant of LockBit ransomware - version 4.0. Throughout this blog, I’ll walk through all the malicious functionalities discovered, complete with explanations and IDA screenshots to show my reverse engineering process step by step. This new version of LockBit 4.0 implements a hybrid-cryptography approach, combining Curve25519 with XChaCha20 for its file encryption scheme.
This version shares similarities with the older LockBit Green variant that is derived from Conti ransomware. While the multi-threading architecture seems more streamlined than previous versions, it still delivers an encryption speed that outpaces most other ransomware families.
As always, LockBit is still my most favorite malware to look at, and I certainly enjoyed doing a deep dive to understand how this version works.
Some Marks & Spencer (M&S) stores have been left with empty food shelves as the retailer continues to struggle with a cyber attack affecting its operations.
Online orders have been paused on the company's website and app since Friday, following problems with contactless pay and Click & collect over the Easter weekend.
The BBC understands food availability should be back to normal by the end of the week.
Meanwhile, security experts say a cyber crime group calling itself DragonForce is behind the mayhem.
This Google Threat Intelligence Group report presents an analysis of detected 2024 zero-day exploits.
Google Threat Intelligence Group (GTIG) tracked 75 zero-day vulnerabilities exploited in the wild in 2024, a decrease from the number we identified in 2023 (98 vulnerabilities), but still an increase from 2022 (63 vulnerabilities). We divided the reviewed vulnerabilities into two main categories: end-user platforms and products (e.g., mobile devices, operating systems, and browsers) and enterprise-focused technologies, such as security software and appliances.
Vendors continue to drive improvements that make some zero-day exploitation harder, demonstrated by both dwindling numbers across multiple categories and reduced observed attacks against previously popular targets. At the same time, commercial surveillance vendors (CSVs) appear to be increasing their operational security practices, potentially leading to decreased attribution and detection.
We see zero-day exploitation targeting a greater number and wider variety of enterprise-specific technologies, although these technologies still remain a smaller proportion of overall exploitation when compared to end-user technologies. While the historic focus on the exploitation of popular end-user technologies and their users continues, the shift toward increased targeting of enterprise-focused products will require a wider and more diverse set of vendors to increase proactive security measures in order to reduce future zero-day exploitation attempts.
