Thousands of Asus routers are being hit with stealthy, persistent backdoors

GreyNoise said it detected the campaign in mid-March and held off reporting on it until after the company notified unnamed government agencies. That detail further suggests that the threat actor may have some connection to a nation-state.

The company researchers went on to say that the activity they observed was part of a larger campaign reported last week by fellow security company Sekoia. Researchers at Sekoia said that Internet scanning by network intelligence firm Censys suggested as many as 9,500 Asus routers may have been compromised by ViciousTrap, the name used to track the unknown threat actor.

The attackers are backdooring the devices by exploiting multiple vulnerabilities. One is CVE-2023-39780, a command-injection flaw that allows for the execution of system commands, which Asus patched in a recent firmware update, GreyNoise said. The remaining vulnerabilities have also been patched but, for unknown reasons, have not received CVE tracking designations.

The only way for router users to determine whether their devices are infected is by checking the SSH settings in the configuration panel. Infected routers will show that the device can be logged in to by SSH over port 53282 using a digital certificate with a truncated key of: ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAo41nBoVFfj4HlVMGV+YPsxMDrMlbdDZ…

To remove the backdoor, infected users should remove the key and the port setting.

People can also determine if they’ve been targeted if system logs indicate that they have been accessed through the IP addresses 101.99.91[.]151, 101.99.94[.]173, 79.141.163[.]179, or 111.90.146[.]237. Users of any router brand should always ensure their devices receive security updates in a timely manner.

Feds charge 16 Russians allegedly tied to botnets used in cyberattacks and spying

Biz & IT, botnet, russian hacking, Security, syndication / /

The hacker ecosystem in Russia, more than perhaps anywhere else in the world, has long blurred the lines between cybercrime, state-sponsored cyberwarfare, and espionage. Now an indictment of a group of Russian nationals and the takedown of their sprawling botnet offers the clearest example in years of how a single malware operation allegedly enabled hacking operations as varied as ransomware, wartime cyberattacks in Ukraine, and spying against foreign governments.

The US Department of Justice today announced criminal charges today against 16 individuals law enforcement authorities have linked to a malware operation known as DanaBot, which according to a complaint infected at least 300,000 machines around the world. The DOJ’s announcement of the charges describes the group as “Russia-based,” and names two of the suspects, Aleksandr Stepanov and Artem Aleksandrovich Kalinkin, as living in Novosibirsk, Russia. Five other suspects are named in the indictment, while another nine are identified only by their pseudonyms. In addition to those charges, the Justice Department says the Defense Criminal Investigative Service (DCIS)—a criminal investigation arm of the Department of Defense—carried out seizures of DanaBot infrastructure around the world, including in the US.

Aside from alleging how DanaBot was used in for-profit criminal hacking, the indictment also makes a rarer claim—it describes how a second variant of the malware it says was used in espionage against military, government, and NGO targets. “Pervasive malware like DanaBot harms hundreds of thousands of victims around the world, including sensitive military, diplomatic, and government entities, and causes many millions of dollars in losses,” US attorney Bill Essayli wrote in a statement.

Since 2018, DanaBot—described in the criminal complaint as “incredibly invasive malware”—has infected millions of computers around the world, initially as a banking trojan designed to steal directly from those PCs’ owners with modular features designed for credit card and cryptocurrency theft. Because its creators allegedly sold it in an “affiliate” model that made it available to other hacker groups for $3,000 to $4,000 a month, however, it was soon used as a tool to install different forms of malware in a broad array of operations, including ransomware. Its targets, too, quickly spread from initial victims in Ukraine, Poland, Italy, Germany, Austria, and Australia to US and Canadian financial institutions, according to an analysis of the operation by cybersecurity firm Crowdstrike.

Researchers cause GitLab AI developer assistant to turn safe code malicious

AI, Artificial Intelligence, Biz & IT, chatbots, large language models, Security / /

Marketers promote AI-assisted developer tools as workhorses that are essential for today’s software engineer. Developer platform GitLab, for instance, claims its Duo chatbot can “instantly generate a to-do list” that eliminates the burden of “wading through weeks of commits.” What these companies don’t say is that these tools are, by temperament if not default, easily tricked by malicious actors into performing hostile actions against their users.

Researchers from security firm Legit on Thursday demonstrated an attack that induced Duo into inserting malicious code into a script it had been instructed to write. The attack could also leak private code and confidential issue data, such as zero-day vulnerability details. All that’s required is for the user to instruct the chatbot to interact with a merge request or similar content from an outside source.

AI assistants’ double-edged blade

The mechanism for triggering the attacks is, of course, prompt injections. Among the most common forms of chatbot exploits, prompt injections are embedded into content a chatbot is asked to work with, such as an email to be answered, a calendar to consult, or a webpage to summarize. Large language model-based assistants are so eager to follow instructions that they’ll take orders from just about anywhere, including sources that can be controlled by malicious actors.

The attacks targeting Duo came from various resources that are commonly used by developers. Examples include merge requests, commits, bug descriptions and comments, and source code. The researchers demonstrated how instructions embedded inside these sources can lead Duo astray.

“This vulnerability highlights the double-edged nature of AI assistants like GitLab Duo: when deeply integrated into development workflows, they inherit not just context—but risk,” Legit researcher Omer Mayraz wrote. “By embedding hidden instructions in seemingly harmless project content, we were able to manipulate Duo’s behavior, exfiltrate private source code, and demonstrate how AI responses can be leveraged for unintended and harmful outcomes.”

Destructive malware available in NPM repo went unnoticed for 2 years

Biz & IT, code repositories, malware, npm, Security / /

Some of the payloads were limited to detonate only on specific dates in 2023, but in some cases a phase that was scheduled to begin in July of that year was given no termination date. Pandya said that means the threat remains persistent, although in an email he also wrote: “Since all activation dates have passed (June 2023–August 2024), any developer following normal package usage today would immediately trigger destructive payloads including system shutdowns, file deletion, and JavaScript prototype corruption.”

Interestingly, the NPM user who submitted the malicious packages, using the registration email address 1634389031@qq[.]com, also uploaded working packages with no malicious functions found in them. The approach of submitting both harmful and useful packages helped create a “facade of legitimacy” that increased the chances the malicious packages would go unnoticed, Pandya said. Questions emailed to that address received no response.

The malicious packages targeted users of some of the largest ecosystems for JavaScript developers, including React, Vue, and Vite. The specific packages were:

Anyone who installed any of these packages should carefully inspect their systems to make sure they’re no longer running. These packages perfectly mimic legitimate development tools, so it may be easy for them to have remained undetected.

“Microsoft has simply given us no other option,” Signal says as it blocks Windows Recall

Biz & IT, microsoft, privacy, recall, Security, signal messenger, Windows / /

But the changes go only so far in limiting the risks Recall poses. As I pointed out, when Recall is turned on, it indexes Zoom meetings, emails, photos, medical conditions, and—yes—Signal conversations, not just with the user, but anyone interacting with that user, without their knowledge or consent.

Researcher Kevin Beaumont performed his own deep-dive analysis that also found that some of the new controls were lacking. For instance, Recall continued to screenshot his payment card details. It also decrypted the database with a simple fingerprint scan or PIN. And it’s unclear whether the type of sophisticated malware that routinely infects consumer and enterprise Windows users will be able to decrypt encrypted database contents.

And as Cunningham also noted, Beaumont found that Microsoft still provided no means for developers to prevent content displayed in their apps from being indexed. That left Signal developers at a disadvantage, so they had to get creative.

With no API for blocking Recall in the Windows Desktop version, Signal is instead invoking an API Microsoft provides for protecting copyrighted material. App developers can turn on the DRM setting to prevent Windows from taking screenshots of copyrighted content displayed in the app. Signal is now repurposing the API to add an extra layer of privacy.

“We hope that the AI teams building systems like Recall will think through these implications more carefully in the future,” Signal wrote Wednesday. “Apps like Signal shouldn’t have to implement ‘one weird trick’ in order to maintain the privacy and integrity of their services without proper developer tools. People who care about privacy shouldn’t be forced to sacrifice accessibility upon the altar of AI aspirations either.”

Signal’s move will lessen the chances of Recall permanently indexing private messages, but it also has its limits. The measure only provides protection when all parties to a chat—at least those using the Windows Desktop version—haven’t changed the default settings.

Microsoft officials didn’t immediately respond to an email asking why Windows provides developers with no granular control over Recall and whether the company has plans to add any.

Windows 11’s most important new feature is post-quantum cryptography. Here’s why.

Biz & IT, Encryption, microsoft, NIST, quantum computing, Security / /

Microsoft is updating Windows 11 with a set of new encryption algorithms that can withstand future attacks from quantum computers in a move aimed at jump-starting what’s likely to be the most formidable and important technology transition in modern history.

Computers that are based on the physics of quantum mechanics don’t yet exist outside of sophisticated labs, but it’s well-established science that they eventually will. Instead of processing data in the binary state of zeros and ones, quantum computers run on qubits, which encompass myriad states all at once. This new capability promises to bring about new discoveries of unprecedented scale in a host of fields, including metallurgy, chemistry, drug discovery, and financial modeling.

Averting the cryptopocalypse

One of the most disruptive changes quantum computing will bring is the breaking of some of the most common forms of encryption, specifically, the RSA cryptosystem and those based on elliptic curves. These systems are the workhorses that banks, governments, and online services around the world have relied on for more than four decades to keep their most sensitive data confidential. RSA and elliptic curve encryption keys securing web connections would require millions of years to be cracked using today’s computers. A quantum computer could crack the same keys in a matter of hours or minutes.

At Microsoft’s BUILD 2025 conference on Monday, the company announced the availability of quantum-resistant algorithms to SymCrypt, the core cryptographic code library in Windows. The updated library is available in Build 27852 and higher versions of Windows 11. Additionally, Microsoft has updated SymCrypt-OpenSSL, its open source project that allows the widely used OpenSSL library to use SymCrypt for cryptographic operations.

FBI warns of ongoing scam that uses deepfake audio to impersonate government officials

AI, deepfake, fbi, Federal Bureau of Investigation, Security / /

The FBI is warning people to be vigilant of an ongoing malicious messaging campaign that uses AI-generated voice audio to impersonate government officials in an attempt to trick recipients into clicking on links that can infect their computers.

“Since April 2025, malicious actors have impersonated senior US officials to target individuals, many of whom are current or former senior US federal or state government officials and their contacts,” Thursday’s advisory from the bureau’s Internet Crime Complaint Center said. “If you receive a message claiming to be from a senior US official, do not assume it is authentic.”

Think you can’t be fooled? Think again.

The campaign’s creators are sending AI-generated voice messages—better known as deepfakes—along with text messages “in an effort to establish rapport before gaining access to personal accounts,” FBI officials said. Deepfakes use AI to mimic the voice and speaking characteristics of a specific individual. The differences between the authentic and simulated speakers are often indistinguishable without trained analysis. Deepfake videos work similarly.

One way to gain access to targets’ devices is for the attacker to ask if the conversation can be continued on a separate messaging platform and then successfully convince the target to click on a malicious link under the guise that it will enable the alternate platform. The advisory provided no additional details about the campaign.

The advisory comes amid a rise in reports of deepfaked audio and sometimes video used in fraud and espionage campaigns. Last year, password manager LastPass warned that it had been targeted in a sophisticated phishing campaign that used a combination of email, text messages, and voice calls to trick targets into divulging their master passwords. One part of the campaign included targeting a LastPass employee with a deepfake audio call that impersonated company CEO Karim Toubba.

In a separate incident last year, a robocall campaign that encouraged New Hampshire Democrats to sit out the coming election used a deepfake of then-President Joe Biden’s voice. A Democratic consultant was later indicted in connection with the calls. The telco that transmitted the spoofed robocalls also agreed to pay a $1 million civil penalty for not authenticating the caller as required by FCC rules.

After latest kidnap attempt, crypto types tell crime bosses: Transfers are traceable

abduction, crime, crypto, france, Paris, Security / /

The sudden spike in copycat attacks in France, Belgium, and Spain over the last few months suggests that crypto robbery as a tactic has caught the attention of organized crime. (This week’s abduction attempt is already being investigated by the organized crime unit of the Parisian police.)

Crypto industry insiders seem convinced that organized crime likes these attacks because of a (mistaken) belief that crypto transfers are untraceable. So people like Chainalysis CEO Jonathan Levin are trying to clue in the crime bosses.

“For whatever reason, there is a perception that’s out there that crypto is an asset that is untraceable, and that really lends itself to criminals acting in a certain way,” Levin said at a recent conference covered by the trade publication Cointelegraph.

“Apparently, the [knowledge] that crypto is not untraceable hasn’t been received by some of the organized crime groups that are actually perpetrating these attacks, and some of them are concentrated in, you know, France, but not exclusively.”

Spies hack high-value mail servers using an exploit from yesteryear

Biz & IT, cross-site scripting, Security, sednit, webmail, xss / /

Threat actors, likely supported by the Russian government, hacked multiple high-value mail servers around the world by exploiting XSS vulnerabilities, a class of bug that was among the most commonly exploited in decades past.

XSS is short for cross-site scripting. Vulnerabilities result from programming errors found in webserver software that, when exploited, allow attackers to execute malicious code in the browsers of people visiting an affected website. XSS first got attention in 2005, with the creation of the Samy Worm, which knocked MySpace out of commission when it added more than one million MySpace friends to a user named Samy. XSS exploits abounded for the next decade and have gradually fizzled more recently, although this class of attacks continues now.

Just add JavaScript

On Thursday, security firm ESET reported that Sednit, a Kremlin-backed hacking group also tracked as APT28, Fancy Bear, Forest Blizzard, and Sofacy—gained access to high-value email accounts by exploiting XSS vulnerabilities in mail server software from four different makers. Those packages are: Roundcube, MDaemon, Horde, and Zimbra.

The hacks most recently targeted mail servers used by defense contractors in Bulgaria and Romania, some of which are producing Soviet-era weapons for use in Ukraine as it fends off an invasion from Russia. Governmental organizations in those countries were also targeted. Other targets have included governments in Africa, the European Union, and South America.

RoundPress, as ESET has named the operation, delivered XSS exploits through spearphishing emails. Hidden inside some of the HTML in the emails was an XSS exploit. In 2023, ESET observed Sednit exploiting CVE-2020-43770, a vulnerability that has since been patched in Roundcube. A year later, ESET watched Sednit exploit different XSS vulnerabilities in Horde, MDaemon, and Zimbra. One of the now-patched vulnerabilities, from MDaemon, was a zero-day at the time Sednit exploited it.

Google introduces Advanced Protection mode for its most at-risk Android users

advanced protection mode, android, Biz & IT, Google, hacking, Security / /

Google is adding a new security setting to Android to provide an extra layer of resistance against attacks that infect devices, tap calls traveling through insecure carrier networks, and deliver scams through messaging services.

On Tuesday, the company unveiled the Advanced Protection mode, most of which will be rolled out in the upcoming release of Android 16. The setting comes as mercenary malware sold by NSO Group and a cottage industry of other exploit sellers continues to thrive. These players provide attacks-as-a-service through end-to-end platforms that exploit zero-day vulnerabilities on targeted devices, infect them with advanced spyware, and then capture contacts, message histories, locations, and other sensitive information. Over the past decade, phones running fully updated versions of Android and iOS have routinely been hacked through these services.

A core suite of enhanced security features

Advanced Protection is Google’s latest answer to this type of attack. By flipping a single button in device settings, users can enable a host of protections that can thwart some of the most common techniques used in sophisticated hacks. In some cases, the protections hamper performance and capabilities of the device, so Google is recommending the new mode mainly for journalists, elected officials, and other groups who are most often targeted or have the most to lose when infected.

“With the release of Android 16, users who choose to activate Advanced Protection will gain immediate access to a core suite of enhanced security features,” Google’s product manager for Android Security, Il-Sung Lee, wrote. “Additional Advanced Protection features like Intrusion Logging, USB protection, the option to disable auto-reconnect to insecure networks, and integration with Scam Detection for Phone by Google will become available later this year.”

AI agents that autonomously trade cryptocurrency aren’t ready for prime time

AI, Biz & IT, chatbots, context manipulation, large language models, prompt injections, Security / /

The researchers wrote:

The implications of this vulnerability are particularly severe given that ElizaOSagents are designed to interact with multiple users simultaneously, relying on shared contextual inputs from all participants. A single successful manipulation by a malicious actor can compromise the integrity of the entire system, creating cascading effects that are both difficult to detect and mitigate. For example, on ElizaOS’s Discord server, various bots are deployed to assist users with debugging issues or engaging in general conversations. A successful context manipulation targeting any one of these bots could disrupt not only individual interactions but also harm the broader community relying on these agents for support

and engagement.

This attack exposes a core security flaw: while plugins execute sensitive operations, they depend entirely on the LLM’s interpretation of context. If the context is compromised, even legitimate user inputs can trigger malicious actions. Mitigating this threat requires strong integrity checks on stored context to ensure that only verified, trusted data informs decision-making during plugin execution.

In an email, ElizaOS creator Shaw Walters said the framework, like all natural-language interfaces, is designed “as a replacement, for all intents and purposes, for lots and lots of buttons on a webpage.” Just as a website developer should never include a button that gives visitors the ability to execute malicious code, so too should administrators implementing ElizaOS-based agents carefully limit what agents can do by creating allow lists that permit an agent’s capabilities as a small set of pre-approved actions.

Walters continued:

From the outside it might seem like an agent has access to their own wallet or keys, but what they have is access to a tool they can call which then accesses those, with a bunch of authentication and validation between.

So for the intents and purposes of the paper, in the current paradigm, the situation is somewhat moot by adding any amount of access control to actions the agents can call, which is something we address and demo in our latest latest version of Eliza—BUT it hints at a much harder to deal with version of the same problem when we start giving the agent more computer control and direct access to the CLI terminal on the machine it’s running on. As we explore agents that can write new tools for themselves, containerization becomes a bit trickier, or we need to break it up into different pieces and only give the public facing agent small pieces of it… since the business case of this stuff still isn’t clear, nobody has gotten terribly far, but the risks are the same as giving someone that is very smart but lacking in judgment the ability to go on the internet. Our approach is to keep everything sandboxed and restricted per user, as we assume our agents can be invited into many different servers and perform tasks for different users with different information. Most agents you download off Github do not have this quality, the secrets are written in plain text in an environment file.

In response, Atharv Singh Patlan, the lead co-author of the paper, wrote: “Our attack is able to counteract any role based defenses. The memory injection is not that it would randomly call a transfer: it is that whenever a transfer is called, it would end up sending to the attacker’s address. Thus, when the ‘admin’ calls transfer, the money will be sent to the attacker.”

DOGE software engineer’s computer infected by info-stealing malware

Biz & IT, CISA, credentials, cybersecurity and infrastructure security agency, department of government efficiency, kyle schutt, passwords, Policy, Security / /

Login credentials belonging to an employee at both the Cybersecurity and Infrastructure Security Agency and the Department of Government Efficiency have appeared in multiple public leaks from info-stealer malware, a strong indication that devices belonging to him have been hacked in recent years.

Kyle Schutt is a 30-something-year-old software engineer who, according to Dropsite News, gained access in February to a “core financial management system” belonging to the Federal Emergency Management Agency. As an employee of DOGE, Schutt accessed FEMA’s proprietary software for managing both disaster and non-disaster funding grants. Under his role at CISA, he likely is privy to sensitive information regarding the security of civilian federal government networks and critical infrastructure throughout the US.

A steady stream of published credentials

According to journalist Micah Lee, user names and passwords for logging in to various accounts belonging to Schutt have been published at least four times since 2023 in logs from stealer malware. Stealer malware typically infects devices through trojanized apps, phishing, or software exploits. Besides pilfering login credentials, stealers can also log all keystrokes and capture or record screen output. The data is then sent to the attacker and, occasionally after that, can make its way into public credential dumps.

“I have no way of knowing exactly when Schutt’s computer was hacked, or how many times,” Lee wrote. “I don’t know nearly enough about the origins of these stealer log datasets. He might have gotten hacked years ago and the stealer log datasets were just published recently. But he also might have gotten hacked within the last few months.”

Lee went on to say that credentials belonging to a Gmail account known to belong to Schutt have appeared in 51 data breaches and five pastes tracked by breach notification service Have I Been Pwned. Among the breaches that supplied the credentials is one from 2013 that pilfered password data for 3 million Adobe account holders, one in a 2016 breach that stole credentials for 164 million LinkedIn users, a 2020 breach affecting 167 million users of Gravatar, and a breach last year of the conservative news site The Post Millennial.
