Microsoft is getting ready to annoy its faithful Windows 10 user base with yet another prompt. From a report: This time, Microsoft wants Windows 10 users to switch from using a local account to their online Microsoft account. As first noticed by the outlet Windows Latest, the most recent Windows 10 update Release Preview includes some information about new notifications added to the operating system intended to make users switch from their local account to their Microsoft account. "New! This update starts the [roll out] of account-related notifications for Microsoft accounts in Settings > Home," reads the update, originally from the official Windows blog, which then lays out its case for using a Microsoft account.

U.S. telecom provider Frontier Communications shut down its systems after a cybercrime group breached some of its IT systems in a recent cyberattack. BleepingComputer reports: Frontier is a leading U.S. communications provider that provides gigabit Internet speeds over a fiber-optic network to millions of consumers and businesses across 25 states. After discovering the incident, the company was forced to partially shut down some systems to prevent the threat actors from laterally moving through the network, which also led to some operational disruptions. Despite this, Frontier says the attackers could access some PII data, although it didn't disclose if it belonged to customers, employees, or both.

"On April 14, 2024, Frontier Communications Parent, Inc. [..] detected that a third party had gained unauthorized access to portions of its information technology environment," the company revealed in a filing with the U.S. Securities and Exchange Commission on Thursday. "Based on the Company's investigation, it has determined that the third party was likely a cybercrime group, which gained access to, among other information, personally identifiable information." Frontier now believes that it has contained the breach, has since restored its core IT systems affected during the incident, and is working on restoring normal business operations.

An anonymous reader shares a report: A financially motivated criminal hacking group says it has stolen a confidential database containing millions of records that companies use for screening potential customers for links to sanctions and financial crime. The hackers, which call themselves GhostR, said they stole 5.3 million records from the World-Check screening database in March and are threatening to publish the data online.

World-Check is a screening database used for "know your customer" checks (or KYC), allowing companies to determine if prospective customers are high risk or potential criminals, such as people with links to money laundering or who are under government sanctions.The hackers told TechCrunch that they stole the data from a Singapore-based firm with access to the World-Check database, but did not name the firm. A portion of the stolen data, which the hackers shared with TechCrunch, includes individuals who were sanctioned as recently as this year.

An anonymous reader quotes a report from Futurism: In a new blog post from LastPass, the password management firm used by countless personal and corporate clients to help protect their login information, the company explains that someone used AI voice-cloning tech to spoof the voice of its CEO in an attempt to trick one of its employees. As the company writes in the post, one of its employees earlier this week received several WhatsApp communications -- including calls, texts, and a voice message -- from someone claiming to be its CEO, Karim Toubba. Luckily, the LastPass worker didn't fall for it because the whole thing set off so many red flags. "As the attempted communication was outside of normal business communication channels and due to the employee's suspicion regarding the presence of many of the hallmarks of a social engineering attempt (such as forced urgency)," the post reads, "our employee rightly ignored the messages and reported the incident to our internal security team so that we could take steps to both mitigate the threat and raise awareness of the tactic both internally and externally."

While this LastPass scam attempt failed, those who follow these sorts of things may recall that the company has been subject to successful hacks before. In August 2022, as a timeline of the event compiled by the Cybersecurity Dive blog detailed, a hacker compromised a LastPass engineer's laptop and used it to steal source code and company secrets, eventually getting access to its customer database -- including encrypted passwords and unencrypted user data like email addresses. According to that timeline, the clearly-resourceful bad actor remained active in the company's servers for months, and it took more than two months for LastPass to admit that it had been breached. More than six months after the initial breach, Toubba, the CEO, provided a blow-by-blow timeline of the months-long attack and said he took "full responsibility" for the way things went down in a February 2023 blog post.

404 Media: An online service is scraping Discord servers en masse, archiving and tracking users' messages and activity across servers including what voice channels they join, and then selling access to that data for as little as $5. Called Spy Pet, the service's creator says it scrapes more than ten thousand Discord servers, and besides selling access to anyone with cryptocurrency, is also offering the data for training AI models or to assist law enforcement agencies, according to its website.

The news is not only a brazen abuse of Discord's platform, but also highlights that Discord messages may be more susceptible to monitoring than ordinary users assume. Typically, a Discord user's activity is spread across disparate servers, with no one entity, except Discord itself, able to see what messages someone has sent across the platform more broadly. With Spy Pet, third-parties including stalkers or potentially police can look up specific users and see what messages they've posted on various servers at once. "Have you ever wondered where your friend hangs out on Discord? Tired of basic search tools like Discord.id? Look no further!" Spy Pet's website reads. It claims to be tracking more than 14,000 servers, 600 million users, and includes a database of more than 3 billion messages.

Cloudflare, in a blog post: Key insights from the first quarter of 2024 include:
1. 2024 started with a bang. Cloudflare's defense systems automatically mitigated 4.5 million DDoS attacks during the first quarter -- representing a 50% year-over-year (YoY) increase.
2. DNS-based DDoS attacks increased by 80% YoY and remain the most prominent attack vector.
3. DDoS attacks on Sweden surged by 466% after its acceptance to the NATO alliance, mirroring the pattern observed during Finland's NATO accession in 2023.

We've just wrapped up the first quarter of 2024, and, already, our automated defenses have mitigated 4.5 million DDoS attacks -- an amount equivalent to 32% of all the DDoS attacks we mitigated in 2023. Breaking it down to attack types, HTTP DDoS attacks increased by 93% YoY and 51% quarter-over-quarter (QoQ). Network-layer DDoS attacks, also known as L3/4 DDoS attacks, increased by 28% YoY and 5% QoQ. When comparing the combined number of HTTP DDoS attacks and L3/4 DDoS attacks, we can see that, overall, in the first quarter of 2024, the count increased by 50% YoY and 18% QoQ. In total, our systems mitigated 10.5 trillion HTTP DDoS attack requests in Q1. Our systems also mitigated over 59 petabytes of DDoS attack traffic -- just on the network-layer.

A crypto wallet maker claimed this week that hackers may be targeting people with an iMessage "zero-day" exploit -- but all signs point to an exaggerated threat, if not a downright scam. From a report: Trust Wallet's official X (previously Twitter) account wrote that "we have credible intel regarding a high-risk zero-day exploit targeting iMessage on the Dark Web. This can infiltrate your iPhone without clicking any link. High-value targets are likely. Each use raises detection risk." The wallet maker recommended iPhone users to turn off iMessage completely "until Apple patches this," even though no evidence shows that "this" exists at all. The tweet went viral, and has been viewed over 3.6 million times as of our publication. Because of the attention the post received, Trust Wallet hours later wrote a follow-up post. The wallet maker doubled down on its decision to go public, saying that it "actively communicates any potential threats and risks to the community."

UnitedHealth, parent company of ransomware-besieged Change Healthcare, says the total costs of tending to the February cyberattack for the first calendar quarter of 2024 currently stands at $872 million. From a report: That's on top of the amount in advance funding and interest-free loans UnitedHealth provided to support care providers reeling from the disruption, a sum said to be north of $6 billion. In its results for the quarter ended March 31, filed today, UnitedHealth stated that the total impact on the company from the attack in Q1 was $0.74 per share, which is expected to rise to a sum between $1.15 and $1.35 per share by the end of the year.

The remediation efforts spent on the attack are ongoing, so the total costs related to business disruption and repairs are likely to exceed $1 billion over time, potentially including the reported $22 million payment made to the ALPHV/BlackCat-affiliated criminals behind the attack. It's a charge that eclipsed that of casino group MGM, which didn't pay a ransom following an attack on its systems last year, and which faces recovery costs of $100 million to rebuild its systems and paying for the fallout from outages, operational disruptions, allegedly leaked data and more.

T-Mobile employees from around the country are reportedly receiving text messages offering them cash in exchange for swapping SIMs. SIM swapping is when cybercriminals trick a cellular service provider into switching a victim's service to a SIM card that they control, essentially hijacking the victim's phone number and gaining access to two-factor authentication codes. From the Mobile Report: The texts offer the employee $300 per SIM swap, and asks the worker to contact them on telegram. The texts all come from a variety of different numbers across multiple area codes, making it more difficult to block. The text also claims they acquired the employee's number "from the T-Mo employee directory." If true, it could mean T-Mobile's employee directory, with contact numbers, has somehow been accessed. It's also possible the bad actor has live/current access to this data, though we consider that less likely due to the fact that some impacted people are former employees who have not worked at the company in months.

Still, the biggest issue here is how this person (or multiple people) obtained the employee phone numbers. We're not sure yet which employees are impacted, but based on comments online it seems at least a few third-party employees are affected, and we've independently confirmed current corporate employees have also received the message. Though we can't say for certain, this likely means the information is not the same data as what was leaked during the Connectivity Source breach [from September]. We can't, however, eliminate that possibility. As mentioned, there are reports that some of the contacted people are former employees, and haven't been employed at T-Mobile for months, so the information being acted upon is likely a few months old at the very least. That being said, we're pretty confident based on corporate employees being included that this is a different source of data being used.

Roku has made two-factor authentication (2FA) mandatory for all users following two credential stuffing attacks that compromised approximately 591,000 customer accounts and led to unauthorized purchases in fewer than 400 cases. The Register reports: Credential stuffing and password spraying are both fairly similar types of brute force attacks, but the former uses known pairs of credentials (usernames and passwords). The latter simply spams common passwords at known usernames in the hope one of them leads to an authenticated session. "There is no indication that Roku was the source of the account credentials used in these attacks or that Roku's systems were compromised in either incident," it said in an update to customers. "Rather, it is likely that login credentials used in these attacks were taken from another source, like another online account, where the affected users may have used the same credentials."

All accounts now require 2FA to be implemented, whether they were affected by the wave of compromises or not. Roku has more than 80 million active accounts, so only a minority were affected, and these have all been issued mandatory password resets. Compromised or not, all users are encouraged to create a strong, unique password for their accounts, consisting of at least eight characters, including a mix of numbers, symbols, and letter cases. [...] Roku also asked users to remain vigilant to suspicious activity regarding its service, such as phishing emails or clicking on dodgy links to rest passwords -- the usual stuff. "In closing, we sincerely regret that these incidents occurred and any disruption they may have caused," it said. "Your account security is a top priority, and we are committed to protecting your Roku account."

The U.S. government is warning that smart locks securing entry to an estimated 50,000 dwellings nationwide contain hard-coded credentials that can be used to remotely open any of the locks. Krebs on SecurityL: The lock's maker Chirp Systems remains unresponsive, even though it was first notified about the critical weakness in March 2021. Meanwhile, Chirp's parent company, RealPage, Inc., is being sued by multiple U.S. states for allegedly colluding with landlords to illegally raise rents. On March 7, 2024, the U.S. Cybersecurity & Infrastructure Security Agency (CISA) warned about a remotely exploitable vulnerability with "low attack complexity" in Chirp Systems smart locks.

"Chirp Access improperly stores credentials within its source code, potentially exposing sensitive information to unauthorized access," CISA's alert warned, assigning the bug a CVSS (badness) rating of 9.1 (out of a possible 10). "Chirp Systems has not responded to requests to work with CISA to mitigate this vulnerability." Matt Brown, the researcher CISA credits with reporting the flaw, is a senior systems development engineer at Amazon Web Services. Brown said he discovered the weakness and reported it to Chirp in March 2021, after the company that manages his apartment building started using Chirp smart locks and told everyone to install Chirp's app to get in and out of their apartments.

Ubisoft has come under fire from players who claim the company has revoked access to a game they had previously purchased. Users attempting to launch "The Crew" on Ubisoft Connect are met with a message stating, "You no longer have access to this game. Why not check the Store to pursue your adventures?" The game has also been moved to a separate "inactive games" section in players' libraries.

While the game can still be launched, it reportedly only plays a limited demo version. Ubisoft has yet to comment on the matter, but some speculate that the decision may be related to the game's reliance on servers that are no longer operational. The incident has sparked concerns among gamers about the control platform holders have over digital purchases. Ubisoft's subscription boss, Philippe Tremblay, recently stated that players will need to get "comfortable" with not owning games.

An anonymous reader shares a report: Shakeeb Ahmed, a cybersecurity engineer convicted of stealing around $12 million in crypto, was sentenced on Friday to three years in prison. In a press release, the U.S. Attorney for the Southern District of New York announced the sentence. Ahmed was accused of hacking into two cryptocurrency exchanges, and stealing around $12 million in crypto, according to prosecutors.

Adam Schwartz and Bradley Bondi, the lawyers representing Ahmed, did not immediately respond to a request for comment. When Ahmed was arrested last year, the authorities described him as "a senior security engineer for an international technology company." His LinkedIn profile said he previously worked at Amazon. But he wasn't working there at the time of his arrest, an Amazon spokesperson told TechCrunch. While the name of one of his victims was never disclosed, Ahmed reportedly hacked into Crema Finance, a Solana-based crypto exchange, in early July 2022.

DOJ-Collected Information Exposed In Data Breach Affecting 340,000 Information Collected An anonymous reader shared this report from Security Week: Economic analysis and litigation support firm Greylock McKinnon Associates, Inc. (GMA) is notifying over 340,000 individuals that their personal and medical information was compromised in a year-old data breach. The incident was detected on May 30, 2023, but it took the firm roughly eight months to investigate and determine what type of information was compromised and to identify the impacted individuals.



According to GMA's notification letter to the affected individuals, a copy of which was submitted to the Maine Attorney General's Office, both personal and Medicare information was compromised in the data breach... "This information may have included your name, date of birth, address, Medicare Health Insurance Claim Number (which contains a Social Security number associated with a member) and some medical information and/or health insurance information," the notification letter reads.

The compromised data, GMA says, was obtained by the US Department of Justice "as part of a civil litigation matter". More than 340,000 individuals were affected by the data breach, the company told the Maine Attorney General's Office. The impacted individuals, however, are "not the subject of this investigation or the associated litigation matters", the company tells the affected individuals.

An anonymous reader shared this report from BleepingComputer: Researchers have demonstrated the "first native Spectre v2 exploit" for a new speculative execution side-channel flaw that impacts Linux systems running on many modern Intel processors. Spectre V2 is a new variant of the original Spectre attack discovered by a team of researchers at the VUSec group from VU Amsterdam. The researchers also released a tool that uses symbolic execution to identify exploitable code segments within the Linux kernel to help with mitigation.

The new finding underscores the challenges in balancing performance optimization with security, which makes addressing fundamental CPU flaws complicated even six years after the discovery of the original Spectre....

As the CERT Coordination Center (CERT/CC) disclosed yesterday, the new flaw, tracked as CVE-2024-2201, allows unauthenticated attackers to read arbitrary memory data by leveraging speculative execution, bypassing present security mechanisms designed to isolate privilege levels. "An unauthenticated attacker can exploit this vulnerability to leak privileged memory from the CPU by speculatively jumping to a chosen gadget," reads the CERT/CC announcement. "Current research shows that existing mitigation techniques of disabling privileged eBPF and enabling (Fine)IBT are insufficient in stopping BHI exploitation against the kernel/hypervisor."
