Risk and financial advisory solutions provider Kroll on Friday disclosed that one of its employees fell victim to a "highly sophisticated" SIM swapping attack. The incident, which took place on August 19, 2023, targeted the employee's T-Mobile account, the company said. "Specifically, T-Mobile, without any authority from or contact with Kroll or its employee, transferred that employee's phone number to the threat actor's phone at their request," it  said  in an advisory. This enabled the unidentified actor to gain access to certain files containing personal information of bankruptcy claimants in the matters of BlockFi , FTX , and Genesis. SIM swapping (aka SIM splitting or simjacking), while generally a benign process, could be exploited by threat actors to fraudulently activate a SIM card under their control with a victim's phone number. This makes it possible to intercept SMS messages and voice calls and receive MFA-related messages that cont

A U.K. citizen who took part in the massive July 2020 hack of Twitter has been sentenced to five years in prison in the U.S. Joseph James O'Connor (aka PlugwalkJoe), 24, was awarded the sentence on Friday in the Southern District of New York, a little over a month  after  he  pleaded guilty  to the criminal schemes. He was  arrested  in Spain in July 2021. The infamous Twitter breach allowed the defendant and his co-conspirators to obtain unauthorized access to backend tools used by Twitter, abusing them to hijack 130 popular accounts to perpetrate a crypto scam that netted them about $120,000 in illegal profits. "In other instances, the co-conspirators sold access to Twitter accounts to others," the U.S. Department of Justice (DoJ)  said . "O'Connor communicated with others regarding purchasing unauthorized access to a variety of Twitter accounts, including accounts associated with public figures around the world." The defendant has also been accused o

A financially motivated cyber actor has been observed abusing Microsoft Azure  Serial Console  on virtual machines (VMs) to install third-party remote management tools within compromised environments. Google-owned Mandiant attributed the activity to a threat group it tracks under the name  UNC3944 , which is also known as Roasted 0ktapus and Scattered Spider. "This method of attack was unique in that it avoided many of the traditional detection methods employed within Azure and provided the attacker with full administrative access to the VM," the threat intelligence firm  said . The emerging adversary, which first came to light late last year, is known to  leverage SIM swapping attacks  to breach telecommunications and business process outsourcing (BPO) companies since at least May 2022. Subsequently, Mandiant also  found  UNC3944 utilizing a loader named STONESTOP to install a malicious signed driver dubbed POORTRY that's designed to terminate processes associated

A U.K. national has pleaded guilty in the U.S. in connection with the July 2020 Twitter attack affecting numerous high-profile accounts and defrauding other users of the platform. Joseph James O'Connor, who also went by the online alias PlugwalkJoe , admitted to "his role in cyberstalking and multiple schemes that involve computer hacking, including the July 2020 hack of Twitter," the U.S. Department of Justice (DoJ) said. The 23-year-old individual was extradited from Spain on April 26 after the Spanish National Court, in February,  approved  the DoJ request to hand over O'Connor to face 14 criminal charges in the U.S. The  massive hack , which took place on July 15, 2020, involved O'Connor and his co-conspirators seizing control of 130 Twitter accounts, including those belonging to Barack Obama, Bill Gates, and Elon Musk, to perpetrate a cryptocurrency scam that netted them $120,000 in a few hours. The attack was made possible by using social engineering te

A persistent intrusion campaign has set its eyes on telecommunications and business process outsourcing (BPO) companies at lease since June 2022. "The end objective of this campaign appears to be to gain access to mobile carrier networks and, as evidenced in two investigations, perform  SIM swapping  activity," CrowdStrike researcher Tim Parisi  said  in an analysis published last week. The financially motivated attacks have been attributed by the cybersecurity company to an actor tracked as Scattered Spider. Initial access to the target environment is said to be undertaken through a variety of methods ranging from social engineering using phone calls and messages sent via Telegram to impersonate IT personnel. This technique is leveraged to direct victims to a credential harvesting site or trick them into installing commercial remote monitoring and management (RMM) tools like Zoho Assist and Getscreen.me. Should the target accounts be secured by two-factor authenticati

Telecom company T-Mobile on Friday confirmed that it was the victim of a security breach in March after the LAPSUS$ mercenary gang managed to gain access to its networks. The acknowledgment came after investigative journalist Brian Krebs  shared  internal chats belonging to the core members of the group indicating that LAPSUS$ breached the company several times in March  prior to the arrest  of its seven members. T-Mobile, in a statement, said that the incident occurred "several weeks ago, with the "bad actor" using stolen credentials to access internal systems. "The systems accessed contained no customer or government information or other similarly sensitive information, and we have no evidence that the intruder was able to obtain anything of value," it added. The VPN credentials for initial access are said to have been obtained from illicit websites like Russian Market with the goal of gaining control of T-Mobile employee accounts, ultimately allowing

Spain's National Police Agency, the Policía Nacional, said last week it dismantled an unnamed cybercriminal organization and arrested eight individuals in connection with a series of SIM swapping attacks that were carried out with the goal of financial fraud. The suspects of the crime ring masqueraded as trustworthy representatives of banks and other organizations and used traditional phishing and smishing techniques to obtain personal information and bank data of victims before draining money from their accounts. "They usurped the identity of their victims through the falsification of official documents and tricked employees of telephone stores into getting the duplicate of SIM cards, cards where they received security confirmation messages from banks that allowed them to empty their victims' accounts," the authorities  said . Seven of the arrests were made in Barcelona and one in Seville. As many as 12 bank accounts were frozen as part of the illicit operation.

A sixth member associated with an international hacking group known as  The Community  has been sentenced in connection with a multimillion-dollar SIM swapping conspiracy, the U.S. Department of Justice (DoJ) said. Garrett Endicott, 22, from the U.S. state of Missouri, who pleaded guilty to charges of wire fraud and aggravated identity theft following an indictment in 2019, was  sentenced  to 10 months in prison and ordered to pay an amount totaling $121,549.37 in restitution. SIM swapping , also called SIM hijacking, refers to an identity theft scheme wherein malicious parties persuade phone carriers into porting their victims' cell services to SIM cards under their control, often facilitated by bribing an employee of a mobile phone provider or by contacting the service provider's customer support by posing as the victim and requesting that the phone number be swapped to a SIM card operated by the group. The goal is to leverage the phone numbers as a gateway to hijack dif

Ten people belonging to a criminal network have been arrested in connection with a series of SIM-swapping attacks that resulted in the theft of more than $100 million by hijacking the mobile phone accounts of high-profile individuals in the U.S. The Europol-coordinated  year-long investigation  was jointly conducted by law enforcement authorities from the U.K., U.S., Belgium, Malta, and Canada. "The attacks orchestrated by this criminal gang targeted thousands of victims throughout 2020, including famous internet influencers, sport stars, musicians and their families," Europol  said  in a statement. "The criminals are believed to have stolen from them over $100 million in cryptocurrencies after illegally gaining access to their phones." The eight suspects, aged 18 to 26, are said to be part of a larger ring, two members of which were nabbed previously in Malta and Belgium. The latest arrests were made in England and Scotland. The sweep comes almost a year afte

Europol, along with the Spanish and the Romanian national police, has arrested 26 individuals in connection with the theft of over €3.5 million ($3.9 million) by hijacking people's phone numbers via SIM swapping attacks. The law enforcement agencies arrested 12 and 14 people in Spain and Romania, respectively, as part of a joint operation against two different groups of SIM swappers, Europol said . The development comes as SIM swapping attacks are emerging as one of the biggest threats to telecom operators and mobile users alike. The increasingly popular and damaging hack is a clever social engineering trick used by cybercriminals to persuade phone carriers into transferring their victims' cell services to a SIM card under their control. The SIM swap then grants attackers access to incoming phone calls, text messages, and one-time verification codes (or one-time passwords ) that various websites send via SMS messages as part of the two-factor authentication (2FA) proc

It appears that at least the United States has started taking the threat of Sim Swapping attacks very seriously. Starting with the country's first-ever conviction for 'SIM Swapping' this February, U.S. Department of Justice has since then announced charges against several individuals for involving in the scheme to siphon millions of dollars in cryptocurrency from victims. In the latest incident, the U.S. authorities on Thursday arrested two more alleged cybercriminals from Massachusetts, charging them with stealing $550,000 in cryptocurrency from at least 10 victims using SIM swapping between November 2015 and May 2018. SIM Swapping, or SIM hijacking, is a technique that typically involves the social engineering of a target's mobile phone provider. An attacker makes a phony call posing as their targets and convinces the mobile phone provider to port the target's phone number to a SIM card belonging to the attacker. Once successful, the attacker can t

Twitter today finally decided to temporarily disable a feature, called ' Tweeting via SMS ,' after it was abused by a hacking group to compromise Twitter CEO Jack Dorsey last week and sent a series of racist and offensive tweets to Dorsey's followers. Dorsey's Twitter account was compromised last week when a hacker group calling itself "Chuckling Squad" replicated a mobile phone number associated with the CEO account and abused this particular feature to post racist, offensive messages and bomb threats from it via SMS. Replicating a mobile phone number associated with someone else is a technique known as " SIM swapping ," where attackers social engineer a victim's mobile phone provider and trick the telecom company to transfer target's phone number to their own SIM card. Once they social engineered an AT&T employee and gained access to Dorsey's phone number, the Chuckling Squad hackers used the 'Tweeting via SMS' feat

The U.S. Department of Justice today announced charges against nine individuals, 6 of which are members of a hacking group called "The Community" and other 3 are former employees of mobile phone providers who allegedly helped them steal roughly $2.5 million worth of the cryptocurrency using a method known as "SIM Swapping." According to the 15-count indictment unsealed today, five Americans and an Irishman related to The Community hacking group are charged with conspiracy to commit wire fraud, as well as wire fraud and aggravated identity theft. Another three Americans, who reportedly are the former employees of mobile phone providers, are charged in a criminal complaint with the wire fraud. SIM Swapping , or SIM Hijacking , is a type of identity theft that typically involves fraudulently porting of the same number to a new SIM card belonging to the attacker. In SIM swapping, attackers social engineer a victim's mobile phone provider by convincing it

A 20-year-old college student who stole cryptocurrency worth more than $5 million by hijacking victims' phone numbers has pleaded guilty and accepted a sentence of 10 years in prison. Ortiz was arrested last year on charges of siphoning millions of dollars in cryptocurrency from around 40 victims using a method commonly known as " SIM swapping ," which typically involves fraudulently porting of the same number to a new SIM card belonging to the attacker. In SIM swapping, attackers social engineer a victim's mobile phone provider by making a phony call posing as their target and claiming that their SIM card has been lost and that they would like to request a SIM swap. The attackers attempt to convince the target's telecommunications company that they are the actual owner of the phone number they want to swap by providing required personal information on the target, like their SSNs and addresses, eventually tricking the telecoms to port the target's pho
