Despite a global decrease in overall ransomware statistics in 2022, annual trend reports show that the UK saw a 17% annual increase in attacker-reported ransomware incidents last year. This increase indicates that ransomware attacks are still common and pose a significant threat to UK businesses.
According to Jumpsec, data from the first half of 2023 indicates that ransomware compromises will continue to rise this year.
The re-emergence of LockBit poses a significant global and local threat, accounting for more than 30% of all UK ransomware incidents and 52% of global incidents in 2023.
LockBit's rise to prominence is attributed to high-profile attacks on Royal Mail, Ion Trading, and Pendragon, and makes LockBit's success in the UK a cause for concern for businesses and organisations.
Karakurt, believed to be an offshoot or rebrand of Conti, has also emerged as a threat to any large UK organisations with assets exceeding £20 million.
Karakurt is responsible for multiple attacks on large UK organisations and is a significant threat to businesses with cash-in-the-bank assets. Their dark web site currently promises that “Lots of summer leaks are coming”.
Vice Society has continued to be a serious threat to the UK education sector, making it by far the most targeted sector in 2022, followed by legal and retail.
SonicWall's report earlier this year claimed that global ransomware volumes declined by 21% year-on-year in 2022, although those in the UK rose 112%.
The rise in UK ransomware volumes is a significant concern and highlights the need for businesses and organisations to take steps to protect themselves against these threats.
The statistics above, and rise in prominence of groups such as LockBit, Karakurt, and Vice Society indicate a trend towards UK organisations.
Building effective best practice cyber-resilience strategies is essential to mitigate the risks of ransomware attacks, and organisations must take this issue seriously.
Organisations should consider the risk posed by third party providers and affiliated organisations when sharing data and access to their services.
