Finland’s Most-Needed Hacker Nabbed in France – Krebs on Safety

Julius “Zeekill” Kivimäki, a 25-year-old Finnish man charged with extorting a neighborhood on-line psychotherapy follow and leaking remedy notes for greater than 22,000 sufferers on-line, was arrested this week in France. A infamous hacker convicted of perpetrating tens of 1000’s of cybercrimes, Kivimäki had been in hiding since October 2022, when he failed to indicate up in courtroom and Finland issued a global warrant for his arrest.

In late October 2022, Kivimäki was charged (and “arrested in absentia,” based on the Finns) with making an attempt to extort cash from the Vastaamo Psychotherapy Heart. In that breach, which occurred in October 2020, a hacker utilizing the deal with “Ransom Man” threatened to publish affected person psychotherapy notes if Vastaamo didn’t pay a six-figure ransom demand.

Vastaamo refused, so Ransom Man shifted to extorting particular person sufferers — sending them focused emails threatening to publish their remedy notes until paid a 500-euro ransom.

When Ransom Man discovered little success extorting sufferers straight, they uploaded to the darkish net a big compressed file containing the entire stolen Vastaamo affected person data.

However as documented by KrebsOnSecurity in November 2022, safety consultants quickly found Ransom Man had mistakenly included a whole copy of their house folder, the place investigators discovered many clues pointing to Kivimäki’s involvement. From that story:

“Amongst those that grabbed a replica of the database was Antti Kurittu, a workforce lead at Nixu Company and a former legal investigator. In 2013, Kurittu labored on an investigation involving Kivimäki’s use of the Zbot botnet, amongst different actions Kivimäki engaged in as a member of the hacker group Hack the Planet (HTP).”

“It was an enormous opsec [operational security] fail, as a result of they’d plenty of stuff in there — together with the person’s non-public SSH folder, and plenty of recognized hosts that we might take an excellent have a look at,” Kurittu informed KrebsOnSecurity, declining to debate specifics of the proof investigators seized. “There have been additionally different tasks and databases.”

Based on the French news site, Kivimäki was arrested round 7 a.m. on Feb. 3, after authorities in Courbevoie responded to a home violence report. Kivimäki had been out earlier with a girl at a neighborhood nightclub, and later the 2 returned to her house however reportedly received right into a heated argument.

Police responding to the scene had been admitted by one other lady — probably a roommate — and located the person inside nonetheless sleeping off a protracted evening. After they roused him and requested for identification, the 6′ 3″ blonde, green-eyed man offered an ID that said he was of Romanian nationality.

The French police had been uncertain. After consulting data on most-wanted criminals, they shortly recognized the person as Kivimäki and took him into custody.

Kivimäki initially gained notoriety as a self-professed member of the Lizard Squad, a primarily low-skilled hacker group that specialised in DDoS assaults. However American and Finnish investigators say Kivimäki’s involvement in cybercrime dates again to no less than 2008, when he was launched to a founding member of what would quickly turn into HTP.

Finnish police stated Kivimäki additionally used the nicknames “Ryan”, “RyanC” and “Ryan Cleary” (Ryan Cleary was really a member of a rival hacker group — LulzSec — who was sentenced to jail for hacking).

Kivimaki and different HTP members had been concerned in mass-compromising net servers utilizing recognized vulnerabilities, and by 2012 Kivimäki’s alias Ryan Cleary was promoting entry to these servers within the type of a DDoS-for-hire service. Kivimäki was 15 years outdated on the time.

The DDoS-for-hire service allegedly operated by Kivimäki in 2012.

In 2013, investigators going by way of units seized from Kivimäki discovered laptop code that had been used to crack greater than 60,000 net servers utilizing a beforehand unknown vulnerability in Adobe’s ColdFusion software program.

KrebsOnSecurity detailed the work of HTP in September 2013, after the group compromised servers inside knowledge brokers LexisNexis, Kroll, and Dun & Bradstreet.

The group used the identical ColdFusion flaws to interrupt into the Nationwide White Collar Crime Heart (NWC3), a non-profit that gives analysis and investigative help to the U.S. Federal Bureau of Investigation (FBI).

As KrebsOnSecurity reported on the time, this small ColdFusion botnet of information dealer servers was being managed by the identical cybercriminals who’d assumed management over ssndob[.]ms, which operated one of many underground’s most dependable companies for acquiring Social Safety Quantity, dates of delivery and credit score file info on U.S. residents.

A number of legislation enforcement sources informed KrebsOnSecurity that Kivimäki was accountable for making an August 2014 bomb threat in opposition to former Sony On-line Leisure President John Smedley that grounded an American Airways aircraft. That incident was extensively reported to have began with a tweet from the Lizard Squad, however Smedley and others stated it began with a name from Kivimäki.

Kivimäki additionally was concerned in calling in a number of pretend bomb threats and “swatting” incidents — reporting pretend hostage conditions at an tackle to immediate a closely armed police response to that location.

Kivimäki’s obvious indifference to hiding his tracks drew the curiosity of Finnish and American cybercrime investigators, and shortly Finnish prosecutors charged him with an array of cybercrime violations. At trial, prosecutors offered proof displaying he’d used stolen bank cards to purchase luxurious items and store vouchers, and took part in a cash laundering scheme that he used to fund a visit to Mexico.

Kivimäki was finally convicted of orchestrating greater than 50,000 cybercrimes. However largely as a result of he was nonetheless a minor on the time (17) , he was given a 2-year suspended sentence and ordered to forfeit EUR 6,558.

As I wrote in 2015 following Kivimäki’s trial:

“The hazard in such a choice is that it emboldens younger malicious hackers by reinforcing the already fashionable notion that there are not any penalties for cybercrimes dedicated by people underneath the age of 18.

Kivimäki is now crowing in regards to the sentence; He’s modified the outline on his Twitter profile to “Untouchable hacker god.” The Twitter account for the Lizard Squad tweeted the information of Kivimäki’s non-sentencing triumphantly: “All of the those who stated we might rot in jail don’t need to comprehend what we’ve been saying for the reason that starting, we now have free passes.”

One thing tells me Kivimäki received’t get off so simply this time, assuming he’s efficiently extradited again to Finland. An announcement by the Finnish police says they’re in search of Kivimäki’s extradition and that they anticipate the method to go easily.

Kivimäki couldn’t be reached for remark. However he has been discussing his case on Reddit utilizing his authorized first title — Aleksanteri (he stopped utilizing his center title Julius when he moved overseas a number of years in the past). In a put up dated Jan. 31, 2022, Kivimäki responded to a different Finnish-speaking Reddit person who stated they had been a fugitive from justice.

“Identical factor,” Kivimäki replied. “We could begin some form of membership? A help group for needed individuals?”
