On Jan. 9, 2024, U.S. authorities arrested a 19-year-old Florida man charged with wire fraud, aggravated identification theft, and conspiring with others to make use of SIM-swapping to steal cryptocurrency. Sources near the investigation inform KrebsOnSecurity the accused was a key member of a prison hacking group blamed for a string of cyber intrusions at main U.S. expertise firms through the summer season of 2022.

Prosecutors say Noah Michael City of Palm Coast, Fla., stole not less than $800,000 from not less than 5 victims between August 2022 and March 2023. In every assault, the victims noticed their e-mail and monetary accounts compromised after struggling an unauthorized SIM-swap, whereby attackers transferred every sufferer’s cell phone quantity to a brand new system that they managed.
The federal government says City glided by the aliases “Sosa” and “King Bob,” amongst others. A number of trusted sources instructed KrebsOnSecurity that Sosa/King Bob was a core member of a hacking group behind the 2022 breach at Twilio, an organization that gives providers for making and receiving textual content messages and telephone calls. Twilio disclosed in Aug. 2022 that an intrusion had uncovered a “restricted quantity” of Twilio buyer accounts by means of a classy social engineering assault designed to steal worker credentials.
Shortly after that disclosure, the safety agency Group-IB published a report linking the attackers behind the Twilio intrusion to separate breaches at greater than 130 organizations, together with LastPass, DoorDash, Mailchimp, and Plex. A number of safety corporations quickly assigned the hacking group the nickname “Scattered Spider.”
Group-IB dubbed the gang by a special identify — 0ktapus — which was a nod to how the prison group phished staff for credentials. The missives requested customers to click on a hyperlink and log in at a phishing web page that mimicked their employer’s Okta authentication web page. Those that submitted credentials have been then prompted to offer the one-time password wanted for multi-factor authentication.

0ktapus used newly-registered domains that usually included the identify of the focused firm, and despatched textual content messages urging staff to click on on hyperlinks to those domains to view details about a pending change of their work schedule. The phishing websites used a Telegram on the spot message bot to ahead any submitted credentials in real-time, permitting the attackers to make use of the phished username, password and one-time code to log in as that worker at the actual employer web site.
0ktapus typically leveraged info or entry gained in a single breach to perpetrate one other. As documented by Group-IB, the group pivoted from its entry to Twilio to assault not less than 163 of its prospects. Amongst these was the encrypted messaging app Sign, which said the breach may have let attackers re-register the telephone quantity on one other system for about 1,900 customers.
Additionally in August 2022, a number of staff at e-mail supply agency Mailchimp supplied their distant entry credentials to this phishing group. In line with an Aug. 12 blog post, the attackers used their entry to Mailchimp worker accounts to steal information from 214 prospects concerned in cryptocurrency and finance.
On August 25, 2022, the password supervisor service LastPass disclosed a breach during which attackers stole some supply code and proprietary LastPass technical info, and weeks later LastPass mentioned an investigation revealed no buyer information or password vaults have been accessed.
Nevertheless, on November 30, 2022 LastPass disclosed a much more critical breach that the corporate mentioned leveraged information stolen within the August breach. LastPass mentioned prison hackers had stolen encrypted copies of some password vaults, in addition to different private info.
In February 2023, LastPass disclosed that the intrusion concerned a extremely complicated, focused assault in opposition to a DevOps engineer who was one in all solely 4 LastPass staff with entry to the company vault. In that incident, the attackers exploited a safety vulnerability in a Plex media server that the worker was working on his dwelling community, and succeeded in putting in malicious software program that stole passwords and different authentication credentials. The vulnerability exploited by the intruders was patched again in 2020, however the worker by no means up to date his Plex software program.
Because it occurs, Plex introduced its personal information breach someday earlier than LastPass disclosed its preliminary August intrusion. On August 24, 2022, Plex’s safety group urged customers to reset their passwords, saying an intruder had accessed buyer emails, usernames and encrypted passwords.
KING BOB’S GRAILS
A evaluation of 1000’s of messages that Sosa and King Bob posted to a number of public boards and Discord servers over the previous two years exhibits that the individual behind these identities was primarily targeted on two issues: Sim-swapping, and buying and selling in stolen, unreleased rap music recordings from standard artists.
Certainly, these messages present Sosa/King Bob was obsessive about discovering new “grails,” the slang time period utilized in some cybercrime dialogue channels to explain recordings from standard artists which have by no means been formally launched. It stands to purpose that King Bob was SIM-swapping necessary folks within the music business to acquire these information, though there’s little to assist this conclusion from the general public chat information obtainable.
“I bought essentially the most music within the com,” King Bob bragged in a Discord server in November 2022. “I bought 1000’s of grails.”
King Bob’s chats present he was notably enamored of stealing the unreleased works of his favourite artists — Lil Uzi Vert, Playboi Carti, and Juice Wrld. When one other Discord person requested if he has Eminem grails, King Bob mentioned he was uncertain.
“I’ve two folders,” King Bob defined. “One with Uzi, Carti, Juicewrld. After which I’ve ‘each different artist.’ Each different artist is unorganized as fuck and has 1000’s of random shit.”
King Bob’s posts on Discord present he shortly grew to become a celeb on Leaked[.]cx, one in all most lively boards for buying and selling, shopping for and promoting unreleased music from standard artists. The extra grails that customers share with the Leaked[.]cx neighborhood, the extra their standing and entry on the discussion board grows.
The final cache of Leaked dot cx listed by the archive.org on Jan. 11, 2024.
And King Bob shared a lot of his purloined tunes with this neighborhood. Nonetheless others he tried to promote. It’s unclear what number of of these gross sales have been ever consummated, however it isn’t uncommon for a prized grail to promote for wherever from $5,000 to $20,000.
In mid-January 2024, a number of Leaked[.]cx regulars started complaining that they hadn’t seen King Bob shortly and have been actually lacking his grails. On or round Jan. 11, the identical day the Justice Division unsealed the indictment in opposition to City, Leaked[.]cx began blocking individuals who have been attempting to go to the positioning from america.
Days later, annoyed Leaked[.]cx customers speculated about what could possibly be the reason for the blockage.
“Probs blocked as a part of king bob investigation i believe?,” wrote the person “Plsdontarrest.” “Doubt he solely hacked US artists/ppl which is why it’s taking place in a number of international locations.”
FORESHADOWING
On Sept. 21, 2022, KrebsOnSecurity instructed the story of a “Foreshadow,” the nickname chosen by a Florida teenager who was working for a SIM-swapping crew when he was abducted, beaten and held for a $200,000 ransom. A rival SIM-swapping group claimed that Foreshadow and his associates had robbed them of their fair proportion of the income from a latest SIM-swap.
In a video launched by his abductors on Telegram, a bloodied, battered Foreshadow was made to say they’d kill him until the ransom was paid.
As I wrote in that story, Foreshadow seems to have served as a “holder” — a time period used to explain a low-level member of any SIM-swapping group who agrees to hold out the riskiest and least rewarding function of the crime: Bodily protecting and managing the assorted cell gadgets and SIM playing cards which can be utilized in SIM-swapping scams.
KrebsOnSecurity has since realized that Foreshadow was a holder for a very lively SIM-swapper who glided by “Elijah,” which was one other nickname that prosecutors say City used.
Shortly after Foreshadow’s hostage video started circulating on Telegram and Discord, a number of identified actors within the SIM-swapping area instructed everybody within the channels to delete any earlier messages with Foreshadow, claiming he was absolutely cooperating with the FBI.
This was not the primary time Sosa and his crew have been hit with violent assaults from rival SIM-swapping teams. In early 2022, a video surfaced on a preferred cybercrime channel purporting to point out attackers hurling a brick by means of a window at an tackle that matches the spacious and upscale home of Urban’s parents in Sanford, Fl.
“Brickings” are among the many “violence-as-a-service” offerings broadly available on many cybercrime channels. SIM-swapping and adjoining cybercrime channels are replete with job affords for in-person assignments and duties that may be discovered if one searches for posts titled, “In the event you reside close to,” or “IRL job” — brief for “in actual life” job.
Plenty of these categorised advertisements are in service of performing brickings, the place somebody is employed to go to a particular tackle and toss a brick by means of the goal’s window. Different typical IRL job affords contain tire slashings and even drive-by shootings.
THE COM
Sosa was identified to be a prime member of the broader cybercriminal neighborhood on-line often called “The Com,” whereby hackers boast loudly about high-profile exploits and hacks that just about invariably start with social engineering — tricking folks over the telephone, e-mail or SMS into giving freely credentials that enable distant entry to company inner networks.
Sosa additionally was lively in a very damaging group of achieved prison SIM-swappers often called “Star Fraud.” Cyberscoop’s AJ Vicens reported final yr that people inside Star Fraud have been doubtless concerned within the high-profile Caesars Leisure an MGM Resorts extortion assaults.
“ALPHV, a longtime ransomware-as-a-service operation regarded as primarily based in Russia and linked to assaults on dozens of entities, claimed accountability for Caesars and MGM assaults in a word posted to its web site earlier this month,” Vicens wrote. “Consultants had mentioned the assaults have been the work of a gaggle tracked variously as UNC 3944 or Scattered Spider, which has been described as an affiliate working with ALPHV made up of individuals in america and Britain who excel at social engineering.”
In February 2023, KrebsOnSecurity revealed information taken from the Telegram channels for Star Fraud and two different SIM-swapping teams displaying these crooks targeted on SIM-swapping T-Cell prospects, and that they collectively claimed access to T-Mobile on 100 separate occasions over a 7-month period in 2022.
The SIM-swapping teams have been in a position to swap focused telephone numbers to a different system on demand as a result of they continually phished T-Cell staff into giving up credentials to employee-only instruments. In every of these instances the aim was the identical: Phish T-Cell staff for entry to inner firm instruments, after which convert that entry right into a cybercrime service that could possibly be employed to divert any T-Cell person’s textual content messages and telephone calls to a different system.
Allison Nixon, chief analysis officer on the New York cybersecurity consultancy Unit 221B, mentioned the rising brazenness of many Com members is a operate of how lengthy it has taken federal authorities to go after guys like Sosa.
“These incidents present what occurs when it takes too lengthy for cybercriminals to get arrested,” Nixon mentioned. “If governments fail to prioritize this supply of menace, violence originating from the Web will have an effect on common folks.”
NO FIXED ADDRESS
The Daytona Seashore Information-Journal reports that City was arrested Jan. 9 and his trial is scheduled to start within the trial time period beginning March 4 in Jacksonville. The publication mentioned the decide overseeing City’s case denied bail as a result of the defendant was a robust flight threat.
At City’s arraignment, it emerged that he had no fastened tackle and had been utilizing an alias to remain at an Airbnb. The decide reportedly mentioned that when a search warrant was executed at City’s residence, the defendant was downloading applications to delete laptop information.
What’s extra, the decide defined, regardless of telling authorities in Might that he wouldn’t have any extra contact together with his co-conspirators and wouldn’t interact in cryptocurrency transactions, he did so anyway.
City entered a plea of not responsible. City’s court-appointed legal professional mentioned her shopper would don’t have any remark right now.
Prosecutors charged City with eight counts of wire fraud, one rely of conspiracy to commit wire fraud, and 5 counts of aggravated identification theft. In line with the federal government, if convicted City faces as much as 20 years in federal jail on every wire fraud cost. He additionally faces a minimal obligatory penalty of two years in jail for the aggravated identification offenses, which can run consecutive to another jail sentence imposed.
