Cybercriminals are taking greater risks by hitting high-profile targets to get bigger payoffs and boost their online
reputational clout, cybersecurity experts say, after a weekend hack crippled airport check-in systems across Europe and stranded thousands of passengers.
The European Union’s cybersecurity agency ENISA confirmed on Monday that the hack on Collins Aerospace,
owned by RTX, was a ransomware attack, but did not say where the attack originated from. The outage, which hit ch
eck-in and baggage drop services, has affected dozens of flights since Friday.
“Broadly, the majority of ransomware activity is still geared towards extortion through data encryption and th
eft,” said Rafe Pilling, Director of Threat Intelligence at Sophos, a British cybersecurity firm.

“The subset of attacks deliberately engineered for maximum disruption
n, often by Western-based groups, are the outliers, but they are becoming more visible and more ambitious,” he added.
It was not clear which group was behind the hack. Ransomware gangs regularly publicize attacks and leak stolen data on
dark web “leak sites,” but websites that monitor those portals did not, as of Monday, detect any group claiming Collins Aerospace, or RTX, as a target.

Ransomware is malicious software used by cybercriminals t
o encrypt a company’s data and demand payment for its release. They typically operate in the shadows, and ghosts
ny try to avoid targets which might earn them unwanted attention from law enforcement agencies.
Other groups, however, are becoming more brazen in the kind of targets they choose, cybersecurity experts say.
In April, a group of hackers dubbed Scattered Spider was widely reported to be behind an attack that crippled B
British retailer Marks & Spencer, preventing one of the best-known names in British retailing from taking online orders for weeks.
Last Thursday, Britain’s National Crime Agency charged two teenagers over a 2024 cyberattack on London’s Transport
for London, which it said caused “significant disruption and millions in losses.”
The NCA said investigators believed the TfL attack was carried out by members of Scattered Spider.
The FBI has said Scattered Spider was involved with approximately 120 network intrusions, and has earned around $115 million in ransom payments.
“It’s clear from the number of recent cyberattacks and their impact that this is a problem that will grow, possibly rap
idly, until software developers get much better at writing secure software and company IT staff get much better at evaluating the security of software their company choses
to purchase or to use remotely,” said Martyn Thomas, Emeritus Professor of IT at Gresham College, London.
“We have been lucky so far, as the motivation of cyber criminals has been disrupted or financially gained,” Thomas said. “If they were to decide to cause serious injury
ry or many deaths, the same attack strategies could be used on critical systems in healthcare or major infrastructure.”
One potential factor adding to the rise in higher profile and more criminally risky ransomware targets is the pursuit
of reputation within criminal circles: The bigger the target, the more online clout cybercriminals have with other hackers.
“A small but determined set of largely Western-based cybercriminals are honing their skills and becoming emboldened
ed by their past success and the success of others,” said Pilling at Sophos.
“Their motivation isn't only financial though and pulling off a high-impact breach also brings social standing and credibility within their peer networks.”
