Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber threat intelligence experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
Business Email Compromise Attacks Can Take Just Hours
Microsoft’s security intelligence team found that Business Email Compromise (BEC) attacks are moving rapidly, with some taking mere minutes. Microsoft found the whole process, from signing in using compromised credentials to registering typo squatting domains and hijacking an email thread, took threat actors only a couple of hours. Such a rapid attack leaves minimal time for organisations to identify and take preventative action. This is worrying when considering the cost of BEC is predicted to more than tens of billions.
Research Reveals ‘Password’ is Still the Most Common Term used by Hackers to Breach Enterprise Networks
In a report of over 800 million breached passwords, vendor Specops identified some worrying results. Some of the key findings from the report include 88% of passwords used in successful attacks consisting of 12 characters or less and the most common base terms used in passwords involving ‘password’, ‘admin’, ‘welcome’ and ‘p@ssw0rd’. The report found that 83% of the compromised passwords satisfied both the length and complexity requirements of cyber security compliance standards such as NIST, GDPR, HIPAA and Cyber Essentials.
Just 10% of Firms Can Resolve Cloud Threats in an Hour
Two-thirds (39%) of global organisations reported a surge in breaches over the past year, with IT complexity increasing and detection and response capabilities worsening, according to Palo Alto Networks. It found that as enterprises move more of their data and workloads to the cloud, they’re finding it increasingly difficult to discover and remediate incidents quickly. Over two-fifths (42%) reported an increase in mean time to remediate, while 90% said they are unable to detect, contain and resolve cyber-threats within an hour. Nearly a third (30%) reported a major increase in intrusion attempts and unplanned downtime. Part of the challenge appears to be the complexity of their cloud security environments – partly caused by tool bloat.

MSPs in the Crosshairs of Ransomware Gangs
Many attacks have heightened attention around third-party risk and the security obligations of MSPs in meeting multiple customers’ IT needs. Attacks such as the ones on RackSpace and LastPass show that some ransomware actors are now intentionally targeting MSPs to access sensitive customer data. It is now believed that some advanced persistent threat (APT) groups could be stepping up their attacks on MSP’s in order to gain sensitive customer data.

Stolen Credentials Increasingly Empower the Cyber Crime Underground
Threat Intelligence provider Flashpoint found that last year threat actors exposed or stole 22.62 billion credentials and personal records, which often make their way to underground forums and cyber criminal markets. This follows a significant increase in market activity; just last year Flashpoint recorded 190 new illicit markets emerge and the continual rise in attacks focused on stealing credentials only further empowers cyber crime underground.
It’s Time to Assess the Potential Dangers of an Increasingly Connected World
As global conflicts continue, cyber has become the fifth front of warfare. The world is approaching 50 billion connected devices, controlling everything from our traffic lights to our nuclear arsenal and we have already seen large-scale cyber attacks. Adding to this, a multitude of infrastructure runs on services ran by a handful of companies; Palo Alto Networks, Cisco and Fortinet control more than 50% of the market for security appliances. As such, an attack on one of these companies could cause a huge ripple effect on their customers.
Mounting Cyber Threats Mean Financial Firms Urgently Need Better Safeguards
According to the International Monetary Fund (IMF) 64% of banks and supervisory authorities do not mandate testing and exercising cyber security and 54% lack dedicated a cyber incident reporting regime. This increases the risk of experiencing a cyber attack. Regularly testing and exercising security will aid any organisation in its cyber resilience.
Insider Threat: Developers Leaked 10m Credentials Including Passwords in 2022
Security provider GitGuardian found that the rate at which developers leaked critical software secrets jumped by 0.5 to reach 5.5 out of every 1,000 commits to GitHub repositories; overall, this amounted to at least 10 million instances of secrets leaking to a public repository. Generic passwords accounted for the majority of leaked secrets (56%) and more than a third (38%) of leaks involved API keys, random number generator seeds and other sensitive strings. These leaks can have worrying consequences for organisations.
Cyber Threat Detections Surges 55% In 2022
Security Provider Trend Micro has said that it stopped 146 billion cyber threats in 2022, a 55% increase on the previous year and evidence of the increase of attacks ramping up. Trend Micro also found a 242% increase in the number of blocked malicious files and an 86% increase in backdoor malware detections with the latter showing an increase in attackers gaining initial access. Furthermore, the number of critical vulnerabilities in 2022 doubled compared to the previous year. Trend Micro noted that this is all likely due to an ever expanding attack surface of organisations.
https://www.infosecurity-magazine.com/news/cyberthreat-detections-surge-55/
European Central Bank Tells Banks to Run Cyber Stress Tests after Rise in Hacker Attacks
The European Central Bank (ECB) will ask all major lenders in the Eurozone to detail by next year, how they would respond to and recover from a successful cyber attack. The ECB is in the process of designing a scenario involving a theoretical breach of the financial system’s cyber defences, which will be sent to all of the 111 banks it assesses to see how they would react. The stress test stems from the increasing amount of cyber attacks. If cyber has shown us anything, it’s that anyone can be a target and performing a stress test would help any organisation prepare for the worst.

Employees Are Feeding Sensitive Business Data to ChatGPT
1 in 20 employees have put sensitive corporate data into popular AI tool ChatGPT, raising concerns that this could result in massive leaks of proprietary information. In some cases, this has involved employees cutting and pasting strategic documents and asking ChatGPT to make a PowerPoint.
Is Ransomware Declining? Not So Fast Experts Say
Security provider CrowdStrike have explained that the perceived decline in ransomware reflects the abilities of threat actors to adapt, splinter and regroup against defensive measures. CrowdStrike expand on this, stating that whilst ransom payments dipped slightly in 2022, there was an uprise in data extortion and ransomware as a service (RaaS).
Preventing Corporate Data Breaches Starts with Remembering that Leaks have Real Victims
The impact a data breach can have on an individual is devastating and ultimately there’s not much an individual can do themselves if the organisation that holds their data isn’t taking the right steps. To best protect themselves and their clients’ data, organisations should look to have appropriate defence in depth controls, including effective asset management, an open security culture, close monitoring of access, utilising strong authentication and maintaining an awareness of the ever changing threat landscape.
https://www.helpnetsecurity.com/2023/03/07/preventing-corporate-data-breaches/
Faced With Likelihood of Ransomware Attacks, Businesses Still Choosing to Pay Up
In a recent report Proofpoint found that globally 76% of organisations experienced ransomware attempts, with 64% eventually infected. Amongst those that had a cyber insurance policy, 82% of insurers stepped up to pay the ransom either in full or partially. The report found that with the rise in number and sophistication of attacks it is more important than ever for proper security training and awareness in organisations.
Experts See Growing Need for Cyber Security Workers as One in Six Jobs go Unfilled
A report by the Information and Communications Technology Council (ICTC) found that 1 in 6 cyber security jobs are unfulfilled and this is only expected to grow in the coming years. The ICTC stated that “This is not just about education or government funding, but about companies willing to provide hands-on training and experience to the next generation of cyber security experts”.

Black Arrow Cyber Advisory 07 March 2023 – Microsoft Word Proof of Concept Exploit Released for Recently Patched RCE Vulnerability
Black Arrow Cyber Advisory 07 March 2023 – Microsoft Word Proof of Concept Exploit Released for Recently Patched RCE Vulnerability
Executive Summary
CVE-2023-21716 is a Microsoft Word critical remote code execution vulnerability discovered last year, which has been patched in Microsoft’s February patch Tuesday. Security Researcher Joshua Drake has released a Proof of Concept (PoC) for the vulnerability and it’s so small it can fit in a tweet. The PoC requires the victim to simply just preview or open a malicious file, which could arrive in a multitude of ways, such as an email.
What’s the risk to my business?
Successful exploitation allows an attacker to remotely execute code, impacting the confidentiality, integrity and availability of the data held by an organisation.
What can I do?
The vulnerability was patched as part of Microsoft’s February patch Tuesday, so only unpatched versions of Microsoft Office Word remain vulnerable. It is therefore recommended to apply the patches if not done so already. Additionally, the impact can be mitigated by enabling protected view in Microsoft Office Word, which is enabled by default. Protected view is a read-only mode where most editing functions are disabled.

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
UK, US Intelligence Agencies Warn Managed Service Providers, including External IT Providers, Are Now Prime Targets for Cyber Attacks
The Five Eyes coalition of international cyber security authorities, this week issued an advisory to warn managed service providers (MSPs), including external IT providers, of an escalating threat of attack from both everyday cyber criminals and state-sponsored threat actors.
MSPs provide or operate information and communications technology services.
With input from cyber security leaders from Australia, Canada, New Zealand, the UK and the US, the NSA provided recommendations to help bolster their cyber defences, including:
Finding and disabling dormant accounts.
Implementing and enforcing multifactor authentication on accounts.
Ensuring contracts clearly map out who owns and is responsible for securing data.
Malicious actors are targeting MSPs to break into their customers' networks and deploy ransomware, steal data, and spy on them, the Five Eyes authorities have formally warned in a joint security alert.
"The UK, Australian, Canadian, New Zealand, and US cyber security authorities expect malicious cyber actors — including state-sponsored advanced persistent threat (APT) groups — to step up their targeting of MSPs in their efforts to exploit provider-customer network trust relationships," the alert warned.
These types of supply-chain or "island-hopping" attacks can prove very lucrative for cyber criminals because once they break into an MSP, they gain access to all of the customers' networks and data being managed, and in turn commit computer crimes and fraud against those customers' customers.
Wannacry – 5 Years On, 68% Of Enterprises Are Still at Risk
5 years on from one of the world’s most damaging ransomware attacks, research from network detection and response leader ExtraHop has found that 68% of enterprises are still running insecure protocol that were exploited by the North Korean ransomware.
The events of 12 May 2017 live on in cyber security lore. WannaCry revealed just how extensive the damage caused by ransomware can be if deployed in large scale – from downtime to ransom paid to reputational damage. Yet despite the danger, huge numbers of organisations are still running SMBv1, the protocol exploited in the WannaCry attacks that has been publicly deprecated since 2014.
You Can’t Eliminate Cyber Attacks, So Focus on Reducing the Blast Radius
Given it is impossible to prevent all cyber attacks, many organisations should look to reduce the size of the company’s attack surface and the limit the “blast radius” of a potential attack.
There is a danger that the biggest risk concerning cyber attacks is that we’re becoming desensitised to them. After all, businesses experience a ransomware attack every 11 seconds—the majority of which the public never hears about. Faced with this reality, it may seem like efforts to safeguard the enterprise are futile. But that’s all the more reason to strengthen your resolve—and switch up your cyber defence strategy.
The core of this strategy should be the concept of “reducing the blast radius” of an attack, and since you can’t completely eliminate cyber attacks, you need to take steps to contain the impact.
This strategy should contain basic blocking and also consider things such as Zero Trust for remote access, traffic inspection, software-based micro-segmentation and other practical measures to reduce your attack surface.

Just In Time? Bosses Are Finally Waking Up to The Cyber Security Threat
Boardrooms have a reputation for not paying much attention to cyber security, but it could be that executives are finally keen to take more interest in securing the systems and networks their businesses rely on.
Senior figures from American, British and Australian cyber security agencies have said that business execs are now more aware of cyber threats and are actively engaging with their chief information security officer (CISO) and information security teams.
Chief execs are starting to ask their CISOs the right questions, rather than leaving them to it because they don't have to understand complex technology. It does feel like a much more engaging strategic conversation, but there can still be a disconnect between knowing what needs to happen, then actually budgeting for and implementing a cyber security strategy.
https://www.zdnet.com/article/just-in-time-bosses-are-finally-waking-up-to-the-cybersecurity-threat/
Most Organisations Hit by Ransomware Would Pay Up If Hit Again
Almost nine in 10 organisations that have suffered a ransomware attack would choose to pay the ransom if hit again, according to a new report, compared with two-thirds of those that have not experienced an attack.
The findings come from a report titled "How business executives perceive ransomware threat" by security company Kaspersky, which states that ransomware has become an ever-present threat, with 64 percent of companies surveyed already having suffered an attack, but more worryingly, that executives seem to believe that paying the ransom is a reliable way of addressing the issue.
The report is based on research involving 900 respondents across North America, South America, Africa, Russia, Europe, and Asia-Pacific. The respondents were in senior non-IT management roles at companies between 50 and 1,000 employees.
Kaspersky claims that in 88 percent of organisations that have had to deal with a ransomware incident, business leaders said they would choose to pay the money if faced with another attack. In contrast, among those that have not so far suffered a ransomware attack, only 67 percent would be willing to pay, and they would be less inclined to do so immediately.

31,000 FTSE 100 Logins Found on Dark Web
Researchers with Outpost24 are reporting over 31,000 corporate credentials for many of the UK’s leading FTSE 100 firms on the dark web. These are the 100 biggest companies listed on the London Stock Exchange by market capitalisation. The researchers used their threat monitoring and auditing tool Blueliv to search dark web sites for the breached credentials.
Key findings from stolen and leaked credentials study:
The majority (81%) of the companies within the FTSE 100 had at least one credential compromised and exposed on the dark web
31,135 total stolen and leaked credentials detected for FTSE 100 companies, with 38% disclosed on the underground in the past 12 months
Nearly half (42%) of FTSE 100 companies have more than 500 compromised credentials exposed on the dark web
Up to 20% of credentials are stolen via malware infection and stealers
11% disclosed in the last 3 months (21% in the last 6 months and over 68% have been exposed for over 12 months)
Over 60% of stolen credentials came from 3 industries – IT/Telecom (23%), Energy and Utility (22%) and Finance (21%)
IT/Telecoms industry is the most at risk with the highest total amount (7,303) and average stolen credentials per company (730), they are most affected by malware infection and have the most amount of stolen credentials disclosed in the last 3 months
On average, healthcare has the highest number of stolen credentials per company (485) from data breach as they found themselves increasingly in the cyber criminals’ crosshairs since the pandemic.

Ransomware: How Executives Should Prepare Given the Current Threat Landscape
As the number of ransomware attacks continue to increase, the response at C-level must be swift and decisive.
Top executives are increasingly dreading the phone call from their fellow employee notifying them that their company has been hit by a cyber attack. Nearly every week in 2021 and early 2022, a prominent organisation has been in the media spotlight as their public relations team struggles to explain how they were attacked and how they can regain consumer confidence. A recent survey showed that 37 percent of organisations surveyed had been affected by ransomware attacks in the last year.
Worse, the days when executive leadership teams could fully delegate responsibility to a CISO are over. Regardless of reality, surveys have shown that about 40 percent of the public perception of fault for a ransomware attack lands squarely on the CEO’s shoulders, and that 36 percent of attacks result in the loss of C-level talent. While executive involvement in the security program does not guarantee a successful defence, it does give the executive leadership team (ELT) a degree of ownership of the final product, as well as the ability to speak confidently and knowledgeably to the public.
What Your Cyber Insurance Application Form Can Tell You About Ransomware Readiness
The annual cyber insurance application form shows what the carriers think you should be doing to best prevent and recover from ransomware attacks. Pay attention.
If it’s the time of year for you to fill out the annual cyber insurance policy application, you will see how the focus for insurance firms is changing. Each year you can get an insight into what insurance vendors are using to rate the risks and threats to your business and what they are stressing firms should have in place as best practice or what they are expecting you should have in place as a baseline set of controls. Not having them in place could affect insurance rates, whether you are able to get cyber coverage at all, or crucially whether they would pay out in the event of you having to make a claim.
This year you might find more questions specifically around ransomware prevention techniques and protections, from Multi Factor Authentication (MFA) to Endpoint Detection and Response (EDR), and email filtering protections to the robustness of your backups.
Make sure to review your cyber insurance policy and its related questionnaire. And ask whether you are doing everything you can to protect your firm and tailoring your actions to align with what your insurance provider has deemed as a best practice.
NCSC Shut Down 2.7 Million Scams in 2021
The UK National Cyber Security Centre (NCSC) removed 2.7 million online scams last year, it was revealed this week, four times as many scams compared to 2020.
The announcement comes as the security agency shared the most recent data from its Active Cyber Defence initiative at the CYBERUK summit earlier in the week.
According to the NCSC, neutralised scams included fake celebrity endorsements and spoof extortion emails.
It has also been revealed that fraud campaigns used common themes, with NHS vaccines and vaccine passports being particularly popular.
Some cyber criminals even posed as NCSC CEO Lindy Cameron – victims received an email claiming the NCSC had prevented £5m of their money from being stolen, and were urged to supply personal information to retrieve the funds.

Security Threats Targeting Remote Workers
Remote work offers great benefits, like reduced commute time, increased freedom, and more time to spend with loved ones. But there can be security downsides if sufficient controls are not in place to protect remote workers against the digital threats that come with working via unsecured connections.
Being on a home network lacks the layered network security of the company environment. Remote work itself is not new, but the dramatic shift to working from home over the past two years means there are more security-naive people who are not in the office.
Not all security threats are the fault of technology. Much of it also comes from human error.
Remote work greatly exacerbates human-activated risk, and people are working in more distracting environments where they may have to answer the door for deliveries or might multitask with household chores. That means mistakes are more likely to happen, like sending an email to the wrong recipient or falling for a malicious email attack.
Recent research by Egress found that 77% of IT leaders said they have seen an increase in security compromises since going remote two years ago.

Password Reuse Is Rampant Among Employees in All Sectors
SpyCloud published an annual analysis of identity exposure among employees of Fortune 1000 companies in key sectors such as technology, finance, retail and telecommunications.
Drawing on a database of over 200 billion recaptured assets, researchers identified over 687 million exposed credentials and PII tied to Fortune 1000 employees, a 26% increase from last year’s analysis.
Analysis of this data showed a 64% password reuse rate, widespread use of easy-to-guess passwords, and a spike in malware-infected devices –– all sources of cyber risk for both employers and consumers who rely on businesses to safeguard their personal data. With remote work blurring the lines between work and personal device use, a larger attack surface compounds the risk of cyber attacks proliferating beyond compromised employee and consumer identities to penetrate corporate networks.
