The British Library has published its lessons learned from the devastating cyber attack that struck in October 2023.

In an eighteen-page report which shows an impressive commitment to transparency, but makes for painful reading, the organisation details how it was compromised by the Rhysida ransomware group during a traumatic timeline of events. In a subsequent press release, the Library also states it hopes other institutions will learn from its findings in the wake of a ‘deeply damaging criminal attack.’

Unfortunately, the report makes clear that in response to tighter security standards, the organisation ceased to be Cyber Essentials Plus certified in 2022, pending replacement of some older systems. In section six, sixteen ‘lessons learned’ form the basis of its future plans and guidance to other organisations:

• Enhance network monitoring capabilities
• Retain on-call external security expertise
• Fully implement multi-factor authentication: Multi-factor authentication needs to be in place on all internet-facing endpoints, regardless of any technical difficulties in doing so.
• Enhance intrusion response processes
• Implement network segmentation
• Practice comprehensive business continuity plans
• Maintain a holistic overview of cyber-risk
• Manage systems lifecycles to eliminate legacy technology
• Prioritise remediation of issues arising from legacy technology
• Prioritise recovery alongside security
• Cyber-risk awareness and expertise at senior level
• Regularly train all staff in evolving risks
• Proactively manage staff and user wellbeing
• Review acceptable personal use of IT
• Collaborate with sector peers
• Implement Government standards, review and audit policies and processes regularly

The exact origin of the hack – which took Library systems offline for months – is unconfirmed, in part due to the scale of the destruction. However the Library’s independent security investigators believe the original breach was caused by either a spear-phishing, brute force or other credential compromise. This allowed hackers access to a remote session on a terminal server that was not yet subject to Multi-Factor Authentication for a user to login.

From there, around 600GB of data (or half a million documents) were exfiltrated, with searches for sensitively-named content such as ‘passport’ and ‘confidential’. Backup copies of twenty-two databases were also made, and removed from the network. Ransomware was also deployed, and the encrypted data used for attempted extortion.

At several points Rhysida are believed to have made their own actions difficult to track – deleting log files and destroying servers to prevent a swift recovery. In a classic ‘double-extortion’ the group also leaked employee and customer data for auction on the dark web in November, with a starting value of 20 Btc (then approximately £600,000). The British Library insists that in line with guidance given by the National Cyber Security Centre, no attempt was made to communicate with the attackers, nor any ransom paid.

The Rhysida ransomware group are also reported to, or have claimed responsibility for, hacks carried out in Chile, Portugal, Kuwait and the United States in the latter half of 2023. Cyber security professionals believe the hackers are Russian-speaking, although evidence is limited.

Lengthy and costly, the cleanup effort has clearly been difficult. The report details that the Library convened Gold and Silver level crisis-management committees, with both private sector and UK state cyber security assistance – although senior staff at the BL were at one point forced to communicate via an emergency WhatsApp call in the absence of official systems. The Library’s main catalogue, containing more than 36-million records, only returned online in ‘read-only’ format in January, and the report states ‘Many staff have been unable to perform significant parts of their roles’ (for more than 3 months.)

The Financial Times have speculated that the recovery costs may eventually total over £7m, which would represent around 40% of the institution’s known financial reserves, although the Library’s Chief Executive, Sir Roly Keating, told the BBC it was too early to calculate the true value.

Ransomware provider LockBit has been taken offline by a joint operation involving law enforcement agencies from eleven countries.

As of the 20th February, a banner on LockBit’s website declares that the site is now under the control of the UK’s National Crime Agency, part of a coordinated operation to take down the group’s ‘command and control’ infrastructure.

Authorities from the NCA, the FBI, Europol and others from around the world swooped on a number of individuals believed to be involved with Lockbit – making arrests in Poland, Ukraine, and in the United States. Two further named individuals are believed to be Russian nationals.

The combined operation (‘Operation Cronos’) also froze more than two hundred cryptocurrency accounts, took down 34 servers and closed 14,000 rogue accounts.

LockBit made headlines as one of the world’s most successful ‘Ransomware-as-a-service’ providers: offering a toolkit any would-be cyber criminal could use to launch their own cyber extortion operation, demanding more than $120m in ransoms for unlocking encrypted data.

The group behind LockBit, which first emerged on Russian forums in 2020, did not respond to Reuters following requests for comment, but published messages on an encrypted messaging app stating it has backup servers not yet ‘touched’ by law enforcement. Investigations by police in numerous countries also revealed copies of stolen data the group claimed to have deleted after negotiating ransom payments.

More than 1,700 organisations are believed to have been compromised by LockBit, many of which are now listed online – and include Royal Mail, the NHS, Boeing and ICBC, China’s largest bank, among many others.

Decryption tools have so far been released to victims of LockBit in 37 languages, as part of the ‘No More Ransom’ project, with UK authorities pledging to reach out to organisations affected by the ransomware.

British intelligence services are actively providing advance warnings to potential ransomware targets in order to thwart impending cyber attacks. On average, every seventy-two hours for the last three months, a team of cyber security experts within GCHQ has been identifying the initial stages of new ransomware attacks targeting British entities, alerting intended victims and preventing attacks from being carried out.

An innovative system known as ‘Early Warning’, overseen by the National Cyber Security Centre (NCSC), is already believed to have thwarted major attacks, and draws on a range of unknown information sources including exclusive intelligence community feeds, public data, commercial inputs, and proprietary resources not available to the public.

This proactive approach, disclosed by several unnamed sources who spoke to Recorded Future News on the condition of anonymity, demonstrates the potential to curtail a significant number of successful cyber breaches. However, it has been noted by insiders that broader participation from organisations is needed to fully capitalise on the benefits of this system.

Currently, the scheme still has its challenges. Only a small fraction of organisations receive alerts – and it is estimated only 2% of those alerted act on the potential threat.

Ironically, a spokesperson from NCSC acknowledged the difficulties faced, stating, “We often struggle to find the correct contact information, or the person believes they’re speaking to a scammer.” The agency has taken steps to provide guidance on distinguishing official communications from criminal attempts to extract money or sensitive data.

In some cases, the delay in notifying potential victims has been so substantial that by the time NCSC establishes contact with the relevant parties, the ransomware attack has already been unleashed.

However, GCHQ clearly has big plans for developing the scheme further, and is encouraging organisations to sign up for Early Warning. As of the close of 2022, a mere 7,819 organisations had registered for the original service, but the NCSC’s annual report reveals that the system alerted over 5,900 user organisations about threats, more than 2,200 about vulnerabilities on their networks, and 56 received early alerts about ransomware attacks.

The National Cyber Security Centre (NCSC) has released its annual ‘Cyber Security Breaches Survey’.

The survey is used to inform government policy on digital security, educate British businesses, and ensure UK cyber space remains safe.

Data collected across over 2,400 business and 850 charities produced some startling statistics concerning the ever-looming threat of cyber-attacks infiltrating UK businesses’ digital footprint.

The report discovered that 39% of UK businesses detected an incoming cyber-attack during 2021. Phishing attacks made up a fifth of all threats identified – the most frequent type of malicious attack.

Organisations also revealed that ransomware was being recognised as a serious digital threat with 56% of businesses stating they have installed or will be introducing a company policy to not pay ransoms to cyber criminals.

Whilst 58% of small and medium businesses disclosed to outsourcing their IT Support service, only 23% of surveyed businesses had a cybersecurity incident management strategy in place that is more advanced than a basic endpoint antivirus.

NCSC promote a blend of regular cyber security learning and training processes within your business to better inform the deployment of traditional cybersecurity software measures across all the organisation’s IT systems.

This multi-layered approach aims to counteract the report’s discovery that a lack of cyber technical expertise amongst UK businesses is to blame for threats going undetected.

Similarly, a company-wide policy of digital hygiene erodes the false assumption that managed cybersecurity strategies are a cost to the business rather than a strategic, protective investment.

31% of business admitted being attacked at least once a week showing that any weak link in an organisation’s cyber defence can have grievous financial implications.

To mitigate this, we recommend organisations follow the NCSC’s guidance and adopt Cyber Essentials and Cyber Essentials +. The scheme requires businesses to meet or exceed an assured set of security requirements each year to protect against common forms of online crime, technology dangers and digital threats.

It is estimated that a Cyber Essentials certification can reduce your organisation’s risk of a cyberattack by 98.5% – contact Lineal to assist with your organisation’s application and to help you meet the requirements for a successful certification or re-certification today.

Bitdefender have released a free decryption tool rescuing those affected by recent versions of GandCrab ransomware.

The free tool enables stricken users to recover data encrypted by various versions of GandCrab without paying a ransom to cybercriminals.

In a joint announcement with Europol, Romanian Police and other law-enforcement agencies, the cybersecurity provider detailed how a team of experts were recently able to gain access to the GandCrab control server, and access decryption keys for the ransomware that would allow safe recovery of data.

Blackhat developers behind GandCrab have claimed to have exploited more than $2 billion in ransom payments worldwide, and appeared to have enjoyed mocking the cybersecurity industry’s attempts to bring them to justice.

GandCrab became the latest nasty ransomware threat in January 2018 – following a disturbing trend of businesses and organisations worldwide struck by malicious encryption software.

Bitdefender’s previous attempts to quash the ransomware resulted in new versions being released by cyber criminals, but the latest recovery of private keys resulted in GandCrab’s developers announcing their ‘retirement’ – allegedly having exploited more than $150m in personal profit over five major versions of the ransomware.

Bitdefender’s recovery tool and instructions for use is available for download from the Bitdefender Labs here. In order to use the tool successfully, affected users must have a working internet connection and at least one copy of the ‘ransom note’ file present on the affected device.

fake invoices

This week’s IT security alert from Lineal – fake invoices which ask users to run a dangerous piece of code.

The example above comes from a fake Word document emailed with a typical text line, such as ‘Please check this invoice’ or ‘Double check my numbers for me’, to an unsuspecting user.

Upon opening, the document appears to load a popup from Office 2016 prompting the user to ‘Enable Content’ for compatibility purposes, before they can view the detail of the ‘invoice.’

In fact, the display is just an image within the word file, and the ‘Enable Content’ content button instead runs a piece of Visual Basic code downloading unknown malware from the internet.

The scam relies on users’ curiosity at the unusual $1999.00 charge, and upon reaching a user still running an outdated version of Microsoft Office.

Several measures can be taken to prevent this kind of attack:

• Don’t click any popup that doesn’t visibly pop ‘open’ in Microsoft and don’t ‘Enable Content’ you can’t see in a document.

• Consider an email filtering service like Barracuda – in the above example, Barracuda had recognised this email as malicious and stripped the code from the document before placing it in the correct email inbox for the intended recipient.

• Invest in a high-quality antivirus and IT security software like ESET – using sophisticated heuristics and live scanning ESET can block this kind of threat, and advanced versions operate a comprehensive watchlist of fake ‘phishing’ scams which might try to imitate legitimate companies online.

• Move to Microsoft Office 365 – Microsoft’s cloud subscription model now ensures that you’ll always have the most up-to-date version of Microsoft Office, and therefore that if a document gives you this kind of message, it may be a scam.
