Top Cyber Stories of the Last Week

  • UK Organisations, Ukraine's Allies Warned of Potential "Massive" Cyber Attacks By Russia

The head of the UK National Cyber Security Centre (NCSC) Lindy Cameron has given an update on Russia’s cyber activity amid its war with Ukraine. Her speech at Chatham House last week came just a few days after Ukraine’s military intelligence agency issued a warning that Russia was “preparing massive cyber attacks on the critical infrastructure of Ukraine and its allies.” This coincides with a new Forrester report that reveals the extent to which the cyber impact of the Russia-Ukraine conflict has expanded beyond the conflict zone with malware attacks propagating into European entities.

Addressing Russian cyber activity this year, Cameron stated that, while we have not seen the “cyber-Armageddon” some predicted, there has been a “very significant conflict in cyber space – probably the most sustained and intensive cyber campaign on record – with the Russian State launching a series of major cyber attacks in support of their illegal invasion in February.”

Russian cyber forces from their intelligence and military branches have been busy launching a huge number of attacks in support of immediate military objectives.

Since the start of the year, the NCSC has been advising UK organisations to take a more proactive approach to cyber security in light of the situation in Ukraine. “There may be organisations that are beginning to think ‘is this still necessary?’ as in the UK we haven’t experienced a major incident related to the war in Ukraine. My answer is an emphatic yes,” Cameron said.

In response to significant recent battlefield set-backs, Putin has been reacting in unpredictable ways, and so we shouldn’t assume that just because the conflict has played out in one way to date, it will continue to go the same way, Cameron added. “There is still a real possibility that Russia could change its approach in the cyber domain and take more risks – which could cause more significant impacts in the UK.” UK organisations and their network defenders should therefore be prepared for this period of elevated alert with a focus on building long-term resilience, which is a “marathon not a sprint,” she said.

  • Cyber Criminals See Allure in BEC Attacks Over Ransomware

While published trends in ransomware attacks have been contradictory — with some firms tracking more incidents and other fewer — business email compromise (BEC) attacks continue to have proven success against organisations.

BEC cases, as a share of all incident-response cases, more than doubled in the second quarter of the year, to 34% from 17% in the first quarter of 2022. That's according to Arctic Wolf's "1H 2022 Incident Response Insights" report, published on 29 September, which found that specific industries — including financial, insurance, business services, and law firms, as well as government agencies — experienced more than double their previous number of cases, the company said.

Overall, the number of BEC attacks encountered per email box has grown by 84% in the first half of 2022, according to data from cyber security firm Abnormal Security.

Meanwhile, so far this year, threat reports released by organisations have revealed contradictory trends for ransomware. Arctic Wolf and the Identity Theft Resource Center (ITRC) have seen drops in the number of successful ransomware attacks, while business customers seem to be encountering ransomware less often, according to security firm Trellix. At the same time, network security firm WatchGuard had a contrary take, noting that its detection of ransomware attacks skyrocketed 80% in the first quarter of 2022, compared with all of last year.

The surging state of BEC landscape is unsurprising because BEC attacks offer cyber criminals advantages over ransomware. Specifically, BEC gains do not rely on the value of cryptocurrency, and attacks are often more successful at escaping notice while in progress. Threat actors are unfortunately very opportunistic.

For that reason, BEC — which uses social engineering and internal systems to steal funds from businesses — continues to be a stronger source of revenue for cyber criminals. In 2021, BEC attacks accounted for 35%, or $2.4 billion, of the $6.9 billion in potential losses tracked by the FBI's Internet Crime Complaint Center (IC3), while ransomware remained a small fraction (0.7%) of the total.

  • Most Hackers Need 5 Hours or Less to Break Into Enterprise Environments

A new survey of 300 ethical hackers provides insight into not only the most common means of initial access, but how a complete end-to-end attack happens.

Around 40% of ethical hackers recently surveyed by the SANS Institute said they can break into most environments they test, if not all. Nearly 60% said they need five hours or less to break into a corporate environment once they identify a weakness.

The SANS ethical hacking survey, done in partnership with security firm Bishop Fox, is the first of its kind and collected responses from over 300 ethical hackers working in different roles inside organisations, with different levels of experience and specialisations in different areas of information security. The survey revealed that on average, hackers would need five hours for each step of an attack chain: reconnaissance, exploitation, privilege escalation and data exfiltration, with an end-to-end attack taking less than 24 hours.

The survey highlights the need for organisations to improve their mean time-to-detect and mean-time-to-contain, especially when considering that ethical hackers are restricted in the techniques they're allowed to use during penetration testing or red team engagements. Using black hat techniques, like criminals do, would significantly improve the success rate and speed of attack.

When asked how much time they typically need to identify a weakness in an environment, 57% of the polled hackers indicated ten or fewer hours: 16% responded six to ten hours, 25% three to five hours, 11% one to two hours and 5% less than an hour.

  • Global Firms Deal with 51 Security Incidents Each Day

Security operations (SecOps) teams are struggling to respond to dozens of cyber security incidents every single day, according to a new report from Trellix.

The security vendor polled 9000 security decision makers from organisations with 500+ employees across 15 markets to compile its latest study, ‘XDR: Redefining the future of cyber security’.

It found that the average SecOps team has to manage 51 incidents per day, with 36% of respondents claiming they deal with 50 to 200 daily incidents. Around half (46%) agreed that they are “inundated by a never-ending stream of cyber-attacks.”

Part of the problem is the siloed nature of security and detection and response systems, the study claimed. Some 60% of respondents argued that poorly integrated products mean teams can’t work efficiently, while a third (34%) admitted they have blind spots. It’s perhaps no surprise, therefore, that 60% admitted they can’t keep pace with the rapid evolution of security threats.

This could be having a major impact on the bottom line. The vast majority (84%) of security decision makers that Trellix spoke to estimated that their organisation lost up to 10% of revenue from security breaches in the past year.

Medium size businesses ($50–$100m in revenue) lost an average of 8% in revenue, versus 5% for large businesses with a turnover of $10bn–$25bn. That could mean hundreds of millions of dollars are being thrown away each year due to inadequate SecOps.

  • Phishing Attacks Crushed Records Last Quarter, Driven by Mobile

Last quarter saw a record-shattering number of observed phishing attacks, fuelled in large part by attempts to target users on their mobile devices.

The latest Anti-Phishing Working Group (APWG) "Phishing Activity Trends Report" for the second quarter of 2022 found 1,097,811 observed phishing attacks, the most the group has ever measured in its history.

The financial sector remained the top target for phishing lures (27.6%), along with other bombarded sectors, including webmail and software-as-a-service providers, social media sites, and cryptocurrency.

But much of the rise in phishing volume is due to a new threat actor focus on mobile devices, specifically vishing (voice phishing) and smishing (SMS phishing) attacks, the report noted.

  • Why Paying the Ransom is Still the Most Common Response to a Ransomware Attack

According to new data from Databarracks, 44% of the organisations who experienced a ransomware assault paid the demanded ransom. 22% made use of ransomware decryption software, while 34% restored data from backups.

The Databarracks 2022 Data Health Check produced the results. The annual report has been collecting data on ransomware, cyber, backup, disaster recovery, and business continuity from more than 400 UK IT decision-makers since 2008.

From the victim’s standpoint, it’s logical why you may pay a ransom. You are unable to handle orders or provide customer support, and losses mount swiftly. Downtime expenses can easily surpass the ransom.

Organisations may believe that paying the ransom will solve the issue more quickly, allowing them to resume operations as usual. This strategy is faulty for a number of causes.

First of all, there is no assurance that your data will be returned. Second, once criminals know an organisation is an easy target, they frequently attack it again. Finally, it conveys the incorrect message. By paying, you are assisting the crooks by demonstrating that their strategies are effective.

  • Ransomware Attacks Continue Increasing: 20% of All Reported Attacks Occurred in the Last 12 Months

Nearly a quarter of businesses have suffered a ransomware attack, with a fifth occurring in the past 12 months, according to a latest annual report from cyber security specialist Hornetsecurity.

The 2022 Ransomware Report, which surveyed over 2,000 IT leaders, revealed that 24% have been victims of a ransomware attack, with one in five (20%) attacks happening in the last year.

Cyber attacks are happening more frequently. Last year's ransomware survey revealed one in five (21%) companies experienced an attack; this year it rose by three percent to 24%.

Attacks on businesses are increasing, and there is a shocking lack of awareness and preparation by IT pros. The survey shows that many in the IT community have a false sense of security as bad actors develop new techniques.

The 2022 Ransomware Report highlighted a lack of knowledge on the security available to businesses. A quarter (25%) of IT professionals either don't know or don't think that Microsoft 365 data can be impacted by a ransomware attack.

Just as worryingly, 40% of IT professionals that use Microsoft 365 in their organisation admitted they do not have a recovery plan in case their Microsoft 365 data was compromised by a ransomware attack.

Microsoft 365 is vulnerable to phishing attacks and ransomware attacks, but with the help of third-party tools, IT admins can back up their Microsoft 365 data securely and protect themselves from such attacks.

Industry responses showed the widespread lack of preparedness from IT professionals and businesses. There has been an increase in businesses not having a disaster recovery plan in place if they do succumb to the heightened threat of a cyber attack.

In 2021, 16% of respondents reported having no disaster recovery plan in place. In 2022, this grew to 19%, despite the rise in attacks.

  • More Than Half of Security Pros Say Risks Higher in Cloud Than On Premise

A recent survey from machine identity solutions provider Venafi aimed to explore the complexity of cloud environments and the resulting impact on cyber security.

Venafi surveyed 1,101 security decision makers (SDMs) in firms with more than 1,000 employees and found that eighty-one percent of companies have experienced a cloud security incident in the last year. Forty-five percent have suffered at least four security incidents in the same period. More than half of security decision makers believe that security risks are higher in the cloud than on-premise.

Twenty-four percent of the firms have more than 10,000 employees. Ninety-two percent of the SDMs are at manager level or above, with 49% at c-suite level or higher.

Most of the firms surveyed believe the underlying issue is the increasing complexity of their cloud deployments. Since these companies already host 41% of their applications in the cloud, and expect to increase this to 57% over the next 18 months, the problem is only likely to worsen in the future.

The ripest target of attack in the cloud is identity management, especially machine identities. Each of these cloud services, containers, Kubernetes clusters and microservices needs an authenticated machine identity – such as a TLS certificate – to communicate securely. If any of these identities is compromised or misconfigured, it dramatically increases security and operational risks.

Respondents reported that the most common cloud incidents are security incidents during runtime (34%), unauthorised access (33%), misconfigurations (32%), vulnerabilities that have not been remediated (24%), and failed audits (19%).

Their primary operational concerns are hijacking of accounts, services or traffic (35%), malware or ransomware (31%), privacy/data access issues such as those from GDPR (31%), unauthorised access (28%), and nation state attacks (26%).

  • How To Outsmart Increasingly Complex Cyber Attacks

Threat detection is harder today than it was two years ago. Next year will be harder than this year. Why? It’s a compounding effect from skills shortages and threat varieties that’s making it more challenging for any one product to handle key security wins. And cyber security is a constantly evolving sector with 2022 a devastating year for cyber security. Both hackers and security experts are always in a battle to outsmart each other.

Even for businesses with good IT departments, data protection can too quickly become an afterthought. Today’s threat landscape is growing, not just in the frequency of attacks (and the number of high-profile breaches recorded in the media) but so is the complexity of any given threat. A recent piece of research found that in 93 percent of cases, an external attacker can breach an organisation’s network perimeter and gain access to local network resources. Following increasing levels of cyber-attacks, it’s a case of “not if I will be hit by a ransomware attack,” but “when…” Organisations need to do something to mitigate the risk and protect their businesses, and they need to do it now. 

Planning and executing a better defence to outsmart attackers and win more security battles doesn’t have to feel like a military operation – but it does require the right service coverage to remove blind spots and reduce emerging risks before they escalate.

  • Top Issues Driving Cyber Security: Growing Number of Cyber Criminals, Variety of Attacks

Fortifying cyber security defences remains a work in progress for many organisations, who acknowledge their shortcomings but have yet to commit the necessary resources to the effort, according to new research from CompTIA.

While a majority of respondents in each of seven geographic regions feels that their company’s cyber security is satisfactory, CompTIA’s “State of Cybersecurity” shows that a much smaller number rank the situation as “completely satisfactory.” Nearly everyone feels that there is room for improvement.

“Companies are aware of the threats they face and the potential consequences of an attack or breach,” said Seth Robinson, VP of industry research, CompTIA. “But they may be underestimating their exposure and how much they need to invest in cyber security. Risk mitigation is the key, the filter through which everything should be viewed.”

Two of the top three issues driving cyber security considerations are the growing volume of cyber criminals, cited by 48% of respondents, and the growing variety of cyber attacks (45%). Additionally, ransomware and phishing have quickly become major areas of concern as digital operations have increased and human error has proven more costly.

“Digital transformation driven by cloud and mobile adoption requires a new strategic approach to cyber security, but this poses significant challenges, both tactically and financially,” Robinson said. “As IT operations and strategy have grown more complex, so has the management of cyber security.”

As cyber security is more tightly integrated with business objectives, zero trust is the overarching policy that should be guiding modern efforts, though its adoption will not take place overnight because it requires a drastically different way of thinking and acting. The report suggests there is small progress in recognising a holistic zero trust approach, but better progress in adopting some elements that are part of an overarching zero trust policy.

  • Cyber Threats Top Business Leaders' Biggest Concerns

Cyber threats are the number one concern for business decision makers, beating worries over economic uncertainty, rising energy costs and hiring, according to insurance provider Travelers. The firm polled over 1200 business leaders to compile its 2022 Travelers Risk Index report.

This is the third time in four years that cyber has emerged as the top concern, with more than half (57%) of respondents believing a future cyber-attack on their organisation is inevitable. A quarter (26%) said their company had already been a breach victim, the seventh successive year this figure has risen.

The top two cyber-related concerns were suffering a security breach (57%), and a system glitch causing computers to crash (55%). Becoming a cyber-extortion victim rose from eighth position to third this year.

However, despite general concern about cyber-threats, business decision-makers may also be guilty of overconfidence in their organisation’s security posture.

Nearly all respondents (93%) said they’re confident their company has implemented best practices to prevent or mitigate a cyber event. Yet most have not deployed endpoint detection and response tools (64%), they haven’t conducted a vendor cyber-assessment (59%), and don’t have an incident response plan (53%). Further, while 90% said they’re familiar with multi-factor authentication (MFA), only 52% had implemented it for remote access. This increasingly matters, not only to mitigate cyber-risk but also to reduce insurance premium costs and increase coverage.

Cyber attacks can shut down a company for a long period of time or even put it out of business, and it’s imperative that companies have a plan in place to mitigate any associated operational and financial disruptions.

Effective measures that have proven to reduce the risk of becoming a cyber victim are available, but based on these survey results, not enough companies are taking action. It’s never too late, and these steps can help businesses avoid a devastating cyber-event.

  • Fired Admin Cripples Former Employer's Network Using Old Credentials

After being laid off, an IT system administrator disrupted the operations of his former employer, a high-profile financial company in Hawaii, hoping to get his job back.

Casey K Umetsu, aged 40, worked as a network admin for the company between 2017 and 2019, when his employer terminated his contract. The US Department of Justice says in a press release that the defendant pled guilty to accessing his former employer's website and making configuration changes to redirect web and email traffic to external computers.

To prolong the business disruption for several more days, Umetsu performed additional actions that essentially locked out the firm's IT team from the website administration panel. In the end, the victimised company learned who was responsible for the sabotage after reporting the cyber security incident to the FBI.

Umetsu is awaiting sentence for his wrongdoings on January 19, 2023. He faces a maximum of 10 years of prison time and a fine of up to $250,000.

While Umetsu's actions are condemnable, the company's security practices cannot be overlooked since Umetsu used credentials that should have been invalidated the moment he got fired.

Black Arrow Cyber Advisory 30/09/2022 – Microsoft SQL Servers Targeted by FARGO Ransomware

Black Arrow Cyber Advisory 30/09/2022 – Microsoft SQL Servers Targeted by FARGO Ransomware

Executive Summary

Unsecured Microsoft SQL servers have been identified as the target for FARGO Ransomware (aka Mallox, aka TargetCompany). This ransomware strain attempts to shut down various processes and services on affected machines before encrypting the data and supplying a ransom note, which contains a warning that data may be published on the public domain if payment is not received.

What’s the risk to me or my business?

At current the threat actors appear to be targeting vulnerable Microsoft SQL servers and gain initial access through either credential brute forcing or through known vulnerabilities that have not been patched. If the threat actor gains access to this server and successfully delivers the ransomware, then data could be encrypted and published on the public domain.

What can I do?

Ensure that leading practices are followed for securing Microsoft SQL servers, including both timely patching of security vulnerabilities when made available, and ensuring that server administrator accounts are protected with strong passwords and multi-factor authentication where available.

Technical Summary

The attack unfolds by first a threat actor having initial access to the MS-SQL process, allowing them to execute a .net file through either CMD or Powershell. This file downloads additional malware, which then generates a .BAT file that shuts down certain processes and services. The ransomware is then injected into AppLaunch.exe, which is a normal windows program. It attempts to delete a registry key, executes recovery deactivation and closes some additional processes including the MS-SQL server. This allows access to the database offline, which allows for the files to be encrypted with the .FARGO3 extension. A ransomware note named ‘RECOVERY FILES.TXT’ is then generated, detailing payment, with a warning that data will be published on the public domain if the payment is not received.

Further information on this ransomware strain is available here, including Indicators of Compromise: FARGO Ransomware (Mallox) Being Distributed to Unsecured MS-SQL Servers - ASEC BLOG (ahnlab.com)
