No more ransomware project

July 28th, 2021

The No More Ransom project celebrates its fifth anniversary today after helping over six million ransomware victims recover their files and saving them almost €1 billion in ransomware payments.

No More Ransom is an online portal launched in July 2016 as a public-private partnership created by law enforcement and industry leaders (Europol’s European Cybercrime Centre, the National High Tech Crime Unit of the Netherlands’ police, McAfee, and Kaspersky).

Today, the No More Ransom project includes 170 partners worldwide, including BleepingComputer, who joined the project in 2018. https://www.nomoreransom.org/

“The decryptors available in the No More Ransom repository have helped more than six million people to recover their files for free,” Europol said.

“This prevented criminals from earning almost a billion euros through ransomware attacks. Currently offering 121 free tools able to decrypt 151 ransomware families, it unites 170 partners from the public and private sector.”

How does it work?

No More Ransom aims to help victims recover their encrypted files, raise awareness of the ransomware threat, and provide ransomware victims and the general public with direct links to report attacks.

To get a decryptor, you have to upload two encrypted files and the ransomware note via No More Ransom’s Crypto Sheriff, which will try to match them against a list of available decryption tools.

Should a match be found you will get a link to a suitable ransomware decryptor that comes with detailed instructions on how to unlock files.

When no decryptor is available, you are advised to check again for a match in the future since new unlock tools are added to the database regularly.

Ransomware victims are advised to never pay as this will finance the criminals future attacks but, instead to take measures to both prevent and to lessen the damage of such attacks:

  • Regularly back up data stored on your computer. Keep at least one copy offline.
  • Do not click on links in unexpected or suspicious emails.
  • Browse and download only official versions of software and always from trusted websites.
  • Use robust security products to protect your system from all threats, including ransomware.
  • Ensure that your security software and operating system are up-to-date.
  • Be wary while browsing the internet and do not click on suspicious links, pop-ups or dialogue boxes.
  • Do not use high privilege accounts (accounts with administrator rights) for daily business.
  • If you become a victim, do not pay! Report the crime and check No More Ransom for decryption tools

GDPR _ Microsoft’s Windows diagnostic data processor feature is GA

July 13th, 2021

Microsoft introduced a new capability in some of its products to help organizations ensure their compliance with data privacy regulations, in particular the European Union’s General Data Protection Regulation (GDPR).

The “Windows diagnostic data processor configuration” became generally available this week, Microsoft announced, It’s enabled in certain Microsoft tools, namely “Desktop AnalyticsUpdate ComplianceMicrosoft Managed Desktop, and the Windows Update for Business deployment service,” .

Data Controller Oversight
Windows collects diagnostic information, and organizations have had rather non-transparent ways of limiting what gets collected. They can just select a pre-set data collection level. Microsoft’s current data collection levels include “Diagnostic Data Off” (previously called “Security”), “Required” (previously called “Basic”) and “Optional” (previously called “Full”). Organizations that use the Windows Update service to keep systems patched need to use the Required option. These nuances, and more, are described here https://docs.microsoft.com/en-us/windows/privacy/configure-windows-diagnostic-data-in-your-organization#enable-windows-diagnostic-data-processor-configuration

Microsoft is positioning the Windows diagnostic data processor configuration capability, as being equivalent to having data controller oversight as required by the GDPR.

From the “Configure Windows Diagnostic Data” document:

The Windows diagnostic data processor configuration enables you to be the controller, as defined by the European Union General Data Protection Regulation (GDPR), for the Windows diagnostic data collected from your Windows devices that meet the configuration requirements.

According to a European Union glossary entry, “the data controller is the party that, alone or jointly with others, determines the purposes and means of the processing of personal data.” The glossary entry adds that “the actual processing may be delegated to another party, called the data processor.”

It seems that Windows diagnostic data processor configuration capability is mostly conceived as a means for organizations to become compliant with the GDPR with regard to their customers. It’s also an assurance about Microsoft’s data collection practices.

Now generally available, the Windows diagnostic data processor configuration further empowers you to manage your organization’s diagnostic data. It provides you familiar tools to support data subject rights, including managing, exporting, or deleting data stored securely in your Azure tenant. It also lets you benefit from our technology without compromise.

The capability also helps organizations to elete data should they get a customer request to do so, which is also a GDPR prerogative. The customer, in GDPR lingo, is known as the “data subject” in such cases.

Handling data subject requests happens though “the admin portal,” according to a note in this “Windows 10 and Privacy Compliance” document.

Prerequisites to Using Diagnostic Data Configuration
There are prerequisites to using the Windows diagnostic data processor configuration capability, which is just supported on devices using “Windows 10 Pro, Education or Enterprise editions, version 1809 with July 2021 update or newer.” In addition, the Windows devices “must be joined to Azure Active Directory.”

The Windows diagnostic data processor configuration capability just applies to data collection by Windows components. It doesn’t apply to the apps running on top of Windows, which have their own data collection practices.

Identity theft

June 28th, 2021

In recent years, there has been a huge rise in the number of cases of identity theft. Around 49 million people have reported falling victim to crimes under this category. Identify fraud caused a total loss of approximately $56 billion in 2020 alone. This spike in identity theft has caused more and more people to think seriously about how they can better protect their identity.

Ransomware – are you ready for the inevitable attack?

June 12th, 2021

The question about whether your organization will be hit with a ransomware attack is not “if” but “when.” Ransomware attacks are still on the rise, and can hit anything from critical infrastructure to smaller enterprises that try to stay under the radar of cybercriminals. An epidemic of security breaches involving ransomware and other types of malware is hitting large companies. In some cases, including the May ransomware attack on Colonial Pipeline, hackers first gained access using compromised accounts. Many such credentials are available for sale online. The ransomware attackers prompted major disruptions to gasoline and jet fuel supplies in the Southeastern US.

Ransomware attacks in North America have soared by 158% and globally by 62% since 2019, according to the 2021 SonicWall Cyber Threat Report

Earlier this month, JBS, the largest US supplier of meat, temporarily shut down its US plants following a ransomware attack on its network.

Game-maker Electronic Arts and the Presque Isle Police Department in Maine are responding to an event they had both been dreading: the theft of gigabytes of private data by hackers who breached their Internet-connected networks.

In EA’s case, the theft included 780GB of source code and tools for FIFA 21,

In another recent incident around 200GB of private data belonging to the Presque Isle Police Department was dumped online by a ransomware group known as Avaddon. The police department was hacked on April 18 and given 10 days to pay a ransom. The department was able to rebuild its network using data backups, and it declined to pay. Earlier this week, Avaddon posted the data on its website hosted on the dark web. The haul included 15,000 emails, according to leak site Distributed Denial of Secrets, which is making the data available to journalists and researchers. The Avaddon site also showed a sampling of police reports and witness statements that date back to at least 2011. The files document incidents of domestic violence, shoplifting, and physical assault and in many cases provide phone numbers, addresses, and other personal information belonging to victims and defendants.

Researchers have discovered yet another massive trove of sensitive data, a dizzying 1.2TB database containing login credentials, browser cookies, autofill data, and payment information extracted by malware that has yet to be identified.

In all, researchers from NordLocker said on Wednesday, the database contained 26 million login credentials, 1.1 million unique email addresses, more than 2 billion browser cookies, and 6.6 million files. In some cases, victims stored passwords in text files created with the Notepad application.

The stash also included over 1 million images and more than 650,000 Word and .pdf files. Additionally, the malware made a screenshot after it infected the computer and took a picture using the device’s webcam. Stolen data also came from apps for messaging, email, gaming, and file-sharing. The data was extracted between 2018 and 2020 from more than 3 million PCs.

Dark web ads for these viruses promise that they can build a virus to attack virtually any app the buyer needs. Once infected, a PC will regularly send pilfered data to a command and control server operated by the attacker. The files can be useful in piecing together the habits and interests of the victims, and if the cookies are used for authentication, they give access to the person’s online accounts.

If you want to determine whether your data was swept up by the malware check the Have I Been Pwned breach notification service, which has uploaded a list compromised accounts.

So what can you do to protect yourself. There is some good advice here https://www.eweek.com/enterprise-apps/how-can-you-prevent-ransomware/

In Theordore Levitt’s book, Thinking About Management, he says managers should ask simple questions. Why do we do it this way? What are the alternatives? What are the potential business costs? Who does it better? It is time for CEOs to start asking these kinds of simple questions about their firm’s security posture.

Contingency plans are part of sound preparedness. One of them should be that, in the case of a ransomware attack: How can the company ensure near-instantaneous recovery if the ransomware attack is ignored? Secondly, how can the company ensure that the data is not corrupted? Knowing and strategizing to have contingency plans in place to address these challenges will give a company’s leadership greater confidence to move forward.

IT executives need to have a seat at the crisis management table and be empowered to speak the truth, even if the other executives are reluctant to hear it. In the midst of a cyber attack, the communication within a company can easily be disrupted, fragmented, and isolated. Weaknesses in internal communication, and a disconnect between business executives and IT executives, is exposed. When business executives have limited information and do not have a full, clear picture of what the company can and can’t do, knee-jerk decisions are made, that lead to financial loss, reputation damage, and business disruption, when with preparation it can be avoided. 

Ransomware criminals have unlimited dollars and every tool and technology needed to succeed. 

Are you ready?

IFRS 17 and IFRS9 – Insurance contracts – are you ready? Ask Synergy Software Systems

June 1st, 2021

IFRS 17 is the newest IFRS standard for insurance contracts and replaces IFRS 4 on January 1st 2022. Mainly to make the financial statement easier to compare across insurance companies and among industries

It states which insurance contracts items should by on the balance and the profit and loss account of an insurance company, how to measure these items and how to present and disclose this information.

This is a big change for insurance companies because data administration, financial presentation and actuarial calculations will need to change!

IFRS 9 explains the classification and the measurement of financial instruments. Hence IFRS 9 helps to improve the information disclosure around financial instrument. Many perceive the information disclosure around financial instruments during the financial crisis as inaccurate for example impairments on financial instruments were taken too late and the amounts were too little.
IFRS 9 makes the classification of each financial instrument more logical and principle based. There are two questions which need to be answered for the classification:
• Why is the company holding the asset; just for collecting the cash flows from the underlying asset, or is the asset also held for trading?
• What kind of asset is the financial asset? Is it a derivative, an equity or a debt instrument? With the SPPI (solely payment of principal and interest) model it can be tested whether an instrument is really a debt instrument.
The classification determines:
• which accounting principle is used;
• should the instrument be measured at fair value or at amortized cost
• and whether earnings and losses should go through the profit and loss account or through the OCI (other comprehensive income) account.
IFRS 9 also includes a more dynamic credit loss model instructing when an insurer should take an impairment on financial assets. The model is forward looking thereby also expected future losses should be taken into account with the impairment.
IFRS 9 also makes hedge accounting possibilities more rule based, thereby being in line with how risks are managed within insurers.

Why are IFRS 9 and IFRS 17 implemented together?
• The insurance liability (IFRS 17) is always closely connected to the financial instruments (IFRS 9) within insurers.
• When a client buys an insurance, the insurance liability is created and with the paid premiums are financial instruments bought.
• Insurers want to reduce the volatility in their earnings and there are some choices within IFRS 9 and IFRS 17 which they can make which can impact the volatility.
• Under IFRS 17 insurers can decide whether results of changing financial risk assumption go through OCI or through the profit and loss account.
• Under IFRS 9 insurers can decide whether changes in equity will go through profit and loss or through OCI.
Both standards will impact earning volatility and hence balance sheet management choices are connected. Consequently, the IFRS board decided it is better that insurers are granted the option to implement both standards together.

Likely impacts
• New concepts and terms are introduced. for example components like unbiased Cash Flows, Risk Adjustment, Discount Rate and CSM
• The standards will have an impact on the presented numbers. Under IFRS 17 the insurance liability needs to be based on updated assumptions which is currently not the case with IFRS 4.
• Faster disclosure is needed, which needs faster processes within the organization
• Insurance liability needs to be specified in a different way, the importance of gross written premiums disappears, while equity will be impacted.
• Risk engines are needed to calculate the CSM and cope with all the different groups
• The general ledger system will change as new measurements are introduced
• Big impact on presentation of the balance and P&L
• More data is needed. with finer granularity and with more history, which challenges internal data quality and consistency and IT performance.
• Reporting timelines are also shortened. both challenging the systems but also the cooperation between different departments.
• Staff training will be needed.

Hostage data – another cybercrime threat.

May 19th, 2021

Hostage Data

Ransomware continues to evolve with new threats. In a recent incident data was not only encrypted, but was also copied back to the criminals. Apple was the target through a supplier. The ransom note stated that without a payment, the data would be auctioned off.

So not only m business issues where you can’t access data, but also the stress of the data possibly being released or sold and who knows what GDPR and other compliance issues and costs.

While you may not work in organizations where data is worth $millions, it is still worth a significant amount, especially when its customer data. Ensure that you already have local data encrypted, and without the keys present, so that criminals can’t read your data.

With SQL Server and TDE the certificate is inside the local master database, and If someone should attach it and get access to the master database, then they could read your databases. An SMK and a DMK, might not offer adequate protection, .
.
Always Encrypted will help, unless you have lots of servers or other machines on your network with the certificates, in which case someone might be able to piece together the keys and read data.

Attacks are increasingly more numerous and creative. Backups might protect against some ransomware, but not when copies of your files are sent to criminals. So consider whether the access you allow from servers to the outside world needs to be more restricted. A challenge administrators, but they have to protect systems.

A cyber-criminal gang that took a major US fuel pipeline offline over the weekend acknowledged the incident in a public statement. “Our goal is to make money and not creating problems for society,” DarkSide wrote on its website.

The US issued emergency legislation on Sunday after Colonial Pipeline was hit by a ransomware cyber-attack. The pipeline carries 2.5 million barrels a day – 45% of the East Coast’s supply of diesel, petrol and jet fuel. The operator took itself offline on Friday after the cyber-attack.

A number of cyber-security researchers, speculated that the cyber-criminal gang could be Russian, because their software avoids encrypting any computer systems where the language is set as Russian.

The incident highlights the risk ransomware can pose to critical national industrial infrastructure, not just businesses.

In addition to a notice on their computer screens, victims of a DarkSide attack receive an information pack informing them that their computers and servers are encrypted. The gang lists all the types of data it has stolen, and sends victims the URL of a “personal leak page” where the data is already loaded, waiting to be automatically published, should the company or organisation not pay before the deadline is up. DarkSide also tells victims it will provide proof of the data it has obtained, and is prepared to delete all of it from the victim’s network.

It has a website on the dark web where it lists all the companies it has hacked and what was stolen, and an “ethics” page where it says which organisations it will not attack. DarkSide also works with “access brokers” – nefarious hackers who work to harvest the login details for as many working user accounts on various services as they can find. Rather than break int accounts and alert users or the service providers, these brokers sit on the usernames and passwords and sell them off to the highest bidders – cyber-criminal gangs who want to use them to carry out much larger crimes.

According to Digital Shadows, a London-based cyber-security firm, DarkSide operates like a business. DarkSide might have bought account login details for remote desktop software such as TeamViewer and Microsoft Remote Desktop. the cyber-criminal gang is likely to be based in a Russian-speaking country, as it avoids attacking companies in post-Soviet states including Russia, Ukraine, Belarus, Georgia, Armenia, Moldova, Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan.

Damages related to cybercrime is set to hit $6 trillion according to Cybersecurity.  Security experts now estimate that cyberattacks cost businesses $1.6 million to recover. Even scarier: in 2019 the average time it took to identify a breach was 7 months according to IBM. According to the FBI, an average of 4,000 ransomware incidents occur daily at an annual cost of $1 billion.

In 2019 his year, following a ransomware attack, the US city of Baltimore estimated its impact at more than $18 million – a much higher cost than the approximately $70,000 ransom, which the city refused to pay.

The arms race between sysadmins that protect infrastructure and criminals that attack it has taken yet another a leap forward.

Snaplogic iPaaS now even better – ask Synergy Software Systems

April 29th, 2021

We’re excited to announce the ‘February 2021’ release of the SnapLogic Intelligent Integration Platform. In this release, there are a number of new Snap Packs: for Marketo and Hubspot. for Marketing Automation, for Microsoft Teams and Power BI for team communication and analytics rly, and OpenAPI to connect to any OpenAPI compliant endpoints.

There is also support for Azure Synapse analytics to our ELT capability. Platform enhancements include :

  • higher productivity through expanded Universal search,
  • platform notifications to Slack,
  • better reliability through Snaplex level scheduling, and more.

Hassle-free connectivity with NEW Snap Packs

New Snap Packs provide out-of-the-box connectivity to key enterprise endpoints.  For example the new Marketo and Hubspot Snap Packs allow you to connect seamlessly to these marketing automation systems. Easily manage marketing assets/campaigns or leads that enter your marketing funnel. While HubSpot Snap Pack supports CRUD (create, read, update, delete) operations, the Marketo Snap Pack allows you to do bulk operations on leads.

With these Snap Packs, quickly sync your assets and leads data across Marketing, Sales, and other functional areas and easily connect to event/survey applications such as Eventbrite, SurveyMonkey, or to Demand Generation tools such as Google Ads, Linkedin, and Analytics endpoints such as Microsoft Power BI and Tableau.

The  Microsoft Power BI Snap Pack is also new and allows you to connect your Power BI instance to hundreds of data sources to bring your data to life with live dashboards and reports. Visualize your data and share insights across teams or embed these in your app or website. The Snap Pack helps you to post, push datasets, read, and edit so that you can easily query data, create/bind entities, import files, and update entities.

For an organization that has a heavy investment in the Microsoft ecosystem, the next Snap Pack the new Microsoft Teams Snap Pack allows you to easily integrate your Microsoft Teams into your enterprise workflows for customers, employees, and teams. This Snap Pack supports accounts such as OAuth2 User, Application, and Dynamic accounts to adhere to your enterprise security standards. Use it to send messages, perform channel operations, and perform team operations. . 

Another key new Snap Pack with this release is the OpenAPI Snap Pack. Most API endpoints today adhere to the OpenAPI specification version 2 or 3. Leverage this Snap Pack to connect to any API endpoint with the published OpenAPI specification so that users can get all the needed documentation while they build their automated workflows. More efficiently connect to any generic endpoint without the need for specific Snaps.

Improved connectivity with other Snap Pack enhancements

Google Sheets Snap Pack now supports JSON based version 4 of the API rather than XML based version 3

Kafka Snap Pack updates now support reading/writing record headers and timestamps, provide option to choose one output document per batch. The later feature allows systems that don’t natively support streaming data to effectively work with Kafka messages by batching them together.

Amazon Redshift and Amazon SQS Snap Packs provide cross-account IAM support that allows organizations to trust and allocate roles with specific access privileges to specific groups or users.

Pushdown to any cloud data warehouse including Azure Synapse 

Over previous releases, Snaplogic has introduced ELT support for Snowflake, Redshift cloud data warehouses so that you can do both ETL and ELT on a single platform. The ELT support is extended to Azure Synapse with this release. With ELT for Azure Synapse, you can accelerate data loading into Azure Synapse to provide ultimate flexibility to transform data by use of all computing resources across SnapLogic and Azure Synpase, thus reducing TCO and enabling a faster time-to-value. 

With the SnapLogic platform yextract data from SaaS applications and databases with a vast number of Snaps. Once the data is in the staging area in Azure Cloud Storage, visually define data transformations, no need to write SQL. These visual transformations are converted into SQL statements and pushed to Azure Synapse for execution.

New features added to SnapLogic ELT make it easy to discover schema and SQL functions in the target cloud data warehouse. The platform provides suggestions for column names during LOAD, INSERT SELECT or MERGE INTO operations. The platform also provides SQL function suggestions when working with your target cloud data warehouse. To deal with large number of SQL functions various cloud data warehouses support, are grouped into different categories to simplify discovery.

Better Ease of Use and improved resiliency with the Platform Updates

The SnapLogic Intelligent Integration platform continues to evolve to make it easy for integration developers, whether they are technical or non-technical, to build and monitor integrations. 

Universal Search, as the name suggests helps you search everything related to SnapLogic, all from a single search box. With the February release, it now performs pipeline searches in addition to the searches in Community, Configured Snaps and Documentation. This is not just a simple text based search. The Iris AI integration assistant provides more relevant search results across generic content (in community and documentation) and specific content from your org (such as pipelines or configured Snaps that you have access to). T

Figure 1: Universal search now supports pipeline searches

To efficiently monitor your integrations use the platform notifications to Slack. Users then get notified via Slack for any notifications from SnapLogic platform such as Daily API Usage, Snaplex Congestion, CPU usage, user activity, in addition to email notifications. Send notifications either on Slack Channels or directly to users.

Figure 2: Configuring Notifications to Slack

Enable Snaplex levels scheduling for all the scheduled tasks. This update reduces the time difference between the scheduled time of task execution and the actual time of task execution. With this update, your scheduled tasks won’t be affected by network disruption of the control plane helping your reliably deliver data that advances business processes and delivers insights.

10 X Faster Reports on SQL! Run Time from 30 Mins to 3 Mins! Ask Synergy Software Systems

April 27th, 2021

The performance degradation of applications running on Windows, and VMs is getting inherently worse. This includes latency issues, queries or reports timing out, crashes, missed SLAs, back office batch jobs bleeding over into production hours, and the litany of “shadow IT” problems that wreak havoc.

Even after migrating to a brand-new flash array, performance problems return because the root source of the problem still exists. The fact is, 30-40% of performance is being robbed by small, fractured, random I/O being generated due to operating system I/O inefficiencies. This is a software problem that is solved by our software.

DymaxIO™ fast data software will quickly:

  • Increase performance automatically – no tuning required. Simply install and watch performance problems disappear.
  • Optimizes writes so maximum payload is carried with every I/O operation.
  • Speed up I/O intensive applications like MS-SQL/Oracle, CRM, ERP, File Servers, Imaging, Web Servers, Backups, VDI.

Install our software on your most troublesome servers and see 30-50% or more of the noisy, garbage I/O offloaded and performance dramatically improved.

Microsoft’s April 2021 Patch Tuesday

April 17th, 2021

Update Tuesday is a monthly cycle when Microsoft releases patches for vulnerabilities . As a best practice, Micorosft encourage customers you to turn on automatic updates.

Security hygiene and patch management are as important as ever as to protect from both sophisticated and common cybercriminal activity. Customers should ensure they are on the latest version of software with current security updates. . It is common for attackers to shift their efforts to exploit recently disclosed vulnerabilities before the latest updates or patches are installed, which is why it is so important that customers migrate to the latest supported software.

This month’s release includes a number of critical vulnerabilities to prioritize, including updates to protect against new vulnerabilities in on-premise Exchange Servers. Given the recent focus on Exchange vulnerabilities, we recommend customers install the updates as soon as possible to ensure they remain protected. Customers using Exchange Online are already protected and do not need to take any action.

More details on all of this month’s updates can be found in the Security Update Guide.. More information on best practice can be found in the following resources:

Critical Windows fix

February 14th, 2021

A critical flaw was discovered in Windows 10 that could allow hackers to unleash a devastating attack on PCs and render the devices useless. Customers who have automatic updates enabled are automatically protected from these vulnerabilities.

Last week Microsoft released a set of fixes affecting Windows TCP/IP implementation that include two Critical Remote Code Execution (RCE) vulnerabilities (CVE-2021-24074, CVE-2021-24094) and an Important Denial of Service (DoS) vulnerability (CVE-2021-24086). The two RCE vulnerabilities are complex which make it difficult to create functional exploits, so they are not likely in the short term. We believe attackers will be able to create DoS exploits much more quickly and expect all three issues might be exploited with a DoS attack shortly after release. Thus, we recommend customers move quickly to apply Windows security updates this month.

The DoS exploits for these CVEs would allow a remote attacker to cause a stop error. Customers might receive a blue screen on any Windows system that is directly exposed to the internet with minimal network traffic.

It is essential that customers apply Windows updates to address these vulnerabilities as soon as possible. If applying the update quickly is not practical, workarounds are detailed in the CVEs that do not require restarting a server. These three vulnerabilities are unique and require separate workarounds depending on the exposure of an affected system; however, they can be thought of in terms of Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) solutions.

The IPv4 workaround simply requires further hardening against the use of Source Routing, which is disallowed in Windows default state. This workaround is documented in CVE-2021-24074 and can be applied through Group Policy or by running a NETSH command that does not require a reboot. The IPv6 workarounds are documented in CVE-2021-24094 and CVE-2021-24086, and require blocking IPv6 fragments, which may negatively impact services with dependencies on IPv6.

It is important that affected systems are patched as quickly as possible because of the elevated risk associated with these vulnerabilities, and downloads for these can be found in the Microsoft Security Update Guide.
