A 36-year-old Russian man recently identified by KrebsOnSecurity as the likely proprietor of the massive RSOCKS botnet has been arrested in Bulgaria at the request of U.S. authorities. At a court hearing in Bulgaria this month, the accused hacker requested and was granted extradition to the United States, reportedly telling the judge, “America is looking for me because I have enormous information and they need it.”

On June 22, KrebsOnSecurity published Meet the Administrators of the RSOCKS Proxy Botnet, which identified Denis Kloster, a.k.a. Denis Emelyantsev, as the apparent owner of RSOCKS, a collection of millions of hacked devices that were sold as “proxies” to cybercriminals looking for ways to route their malicious traffic through someone else’s computer.
A native of Omsk, Russia, Kloster came into focus after KrebsOnSecurity followed clues from the RSOCKS botnet master’s identity on the cybercrime forums to Kloster’s personal blog, which featured musings on the challenges of running a company that sells “security and anonymity services to customers around the world.” Kloster’s blog even included a group photo of RSOCKS employees.
“Thanks to you, we are now developing in the field of information security and anonymity!,” Kloster’s blog enthused. “We make products that are used by thousands of people around the world, and this is very cool! And this is just the beginning!!! We don’t just work together and we’re not just friends, we’re Family.”
The Bulgarian news outlet 24Chasa.bg reports that Kloster was arrested in June at a co-working space in the southwestern ski resort town of Bansko, and that the accused asked to be handed over to the American authorities.
“I have hired a lawyer there and I want you to send me as quickly as possible to clear these baseless charges,” Kloster reportedly told the Bulgarian court this week. “I am not a criminal and I will prove it in an American court.”
Launched in 2013, RSOCKS was shut down in June 2022 as part of an international investigation into the cybercrime service. According to the Justice Department, the RSOCKS botnet initially targeted Internet of Things (IoT) devices, including industrial control systems, time clocks, routers, audio/video streaming devices, and smart garage door openers; later in its existence, the RSOCKS botnet expanded into compromising additional types of devices, including Android devices and conventional computers, the DOJ said.
The Justice Department’s June 2022 statement about that takedown cited a search warrant from the U.S. Attorney’s Office for the Southern District of California, which also was named by Bulgarian news outlets this month as the source of Kloster’s arrest warrant.
When asked about the existence of an arrest warrant or criminal charges against Kloster, a spokesperson for the Southern District said, “no comment.”
Update, Sept. 24, 9:00 a.m. ET: Kloster was named in a 2019 indictment (PDF) unsealed Sept. 23 by the Southern District court.

24Chasa said the defendant’s surname is Emelyantsev and that he only recently adopted the last name Kloster, which is his mother’s maiden name.
As KrebsOnSecurity reported in June, Kloster also appears to be a major player in the Russian email spam industry. In several private exchanges on cybercrime forums, the RSOCKS administrator claimed ownership of the RUSdot spam forum. RUSdot is the successor forum to Spamdot, a far more secretive and restricted forum where most of the world’s top spammers, virus writers and cybercriminals collaborated for years before the community’s implosion in 2010.
Email spam — and in particular malicious email sent via compromised computers — is still one of the biggest sources of malware infections that lead to data breaches and ransomware attacks. So it stands to reason that as administrator of Russia’s most well-known forum for spammers, the defendant in this case probably knows quite a bit about other top players in the botnet spam and malware community.

Despite maintaining his innocence, Kloster reportedly told the Bulgarian judge that he could be useful to American investigators.
“America is looking for me because I have enormous information and they need it,” Kloster told the court, according to 24Chasa. “That’s why they want me.”
The Bulgarian court agreed, and granted his extradition. Kloster’s fiancee also attended the extradition hearing, and reportedly wept in the hall outside the entire time.
Kloster turned 36 while awaiting his extradition hearing, and may soon be facing charges that carry punishments of up to 20 years in prison.
When it comes to passwords, most of us would love nothing more than to set it and forget it. But that’s exactly what hackers are hoping for — in fact, it makes their job a lot easier. This means the best line of defense is frequent password changes.
But how often should you create new passwords? Cybersecurity experts recommend changing your password every three months. There may even be situations where you should change your password immediately, especially if a cybercriminal has access to your account.
This article explores those exact situations and covers some of the best password practices you can use to help safeguard these important combinations of letters and numbers.
There are some situations where you’ll want to change your password immediately.
If you think someone has hacked your account, it’s important to act fast and change your password. Did everyone in your address book get a strange email that looks like it’s from you? Change your email password. Are your Facebook friends getting a new friend request from you? Something’s not right, so you’ll want to change your password.
This can help limit the amount of time a cybercriminal has access to your account.
If there’s a password breach at work or within a company you do business with, you’ll want to change the password for any affected accounts. If you use that password for any other websites, you’ll definitely want to change your password to those accounts. If hackers get access to your password, they may try it on multiple websites to see what else they can steal.
As much as possible, try to avoid logging into your secure accounts on public Wi-Fi, such as at a library or cafe. Generally, an unsecure network means your online activity is public. If you need to use an unsecure network, change your password once you’re on a secure network.
It can also be a good idea to look into a smart VPN like McAfee Secure VPN, which automatically turns on to protect your personal data and credit card information even if you need to use public Wi-Fi.
Your personal information could be at risk if malware infects your computer. If you have quality antivirus software (like what’s included in McAfee Total Protection) and it detects malware, you’ll want to change your passwords from another device.
If you no longer have contact with someone, there’s no need for them to remain on your Netflix or Amazon account. There’s also no need for an ex to share a bank account or have mobile app access. Create new passwords when you’re no longer sharing an account with someone.
You may have an account you haven’t used in a year, such as from an online retailer. Change old passwords for seldom-used accounts and close the account if you don’t intend to use it again.
A good password can make it more difficult for hackers to access your accounts. But what exactly makes a strong password? Here are a few criteria.
A cybercriminal may use a variety of strategies to access your passwords. Here are some of their most common tactics.
When it comes to keeping your data secure, password complexity is just the beginning. Here are a few additional tips for keeping your passwords safe.
Review the passwords for all of your accounts. Make sure you’re not using any for multiple websites. See if your passwords are guessable. Do they include personal information like birthdays or addresses? If you find passwords that are weak or repeated, change those first.
Set up multi-factor authentication for important accounts, such as with financial institutions. Logging into a website with two-factor authentication requires you to enter a code sent by text or email in addition to a username and password.
Some accounts require multi-factor authentication with biometric factors for added security, such as a thumbprint or face scan. Using multi-factor authentication with long, complicated passwords can make an account more secure.
A password manager like McAfee True Key can help prevent unauthorized access to your online accounts by protecting your passwords with strong encryption. It also comes with a password generator to help you create complex passwords while storing them safely.
If you have old or weak passwords or use them on multiple sites, a password manager can generate new ones. It’ll then keep track of them and sign you in to apps and websites — with you only having to remember one master password.
Let McAfee True Key help you defend your personal data. The password management software makes dealing with passwords secure and easy.
McAfee True Key stores your passwords on your device using the strongest encryption available. Once you use a master password to log into True Key, it’ll auto-fill your passwords for any apps or websites you visit. For added convenience, True Key securely syncs your information across all of your devices so you can access it wherever you need it.
While McAfee manages your secure passwords, you can continue enjoying the internet the way it was intended — free from hackers.

In the first part of this blog series on Unscrambling Cybersecurity Acronyms, we provided a high-level overview of the different threat detection and response solutions and went over how to find the right solution for your organization. In this blog, we’ll do a deeper dive on two of these solutions – Endpoint Detection and Response (EDR) and Managed Endpoint Detection and Response (MEDR). However, first let’s take a look back at the history of endpoint security solutions and understand how we got EDR and MEDR security solutions.
The very first endpoint security solutions started out as anti-virus solutions (AV) with basic security functionality that relied heavily on signature-based detection. These solutions were effective against known threats where a signature was created, but ineffective against unknown threats such as new and emerging attacks. That meant that organizations struggled to stay ahead of attackers, who were continuously evolving their techniques to evade detection with new types of malware.
To address this problem, AV vendors added detection technologies such as heuristics, reputational analysis, behavioral protection, and even machine learning to their solutions, which became known as Endpoint Protection Platforms (EPP). These unified solutions were effective against both known and unknown threats and frequently used multiple approaches to prevent malware and other attacks from infecting endpoints.
As cyberattacks grew increasingly sophisticated though, many in the cybersecurity industry recognized that protection against threats wasn’t enough. Effective endpoint security had to include detection and response capabilities to quickly investigate and remediate the inevitable security breach. This led to the creation of EDR security solutions, which focused on post-breach efforts to contain and clean up attacks on compromised endpoints.
Today, most endpoint security vendors combine EPP and EDR solutions into a single, converged solution that provides holistic defense to customers with protection, detection, and response capabilities. Many vendors are also offering EDR as a managed service (also known as MEDR) to customers who need help in securing their endpoints or who don’t have the resources to configure and manage their own EDR solution. Now that we’ve gone over how endpoint security evolved into EDR and MEDR security solutions, let’s cover EDR and MEDR in more depth.
EDR solutions continuously monitor your endpoints for threats, alert you in case suspicious activity is detected, and allow you to investigate, respond to and contain potential attacks. Moreover, many EDR security solutions provide threat hunting functionality to help you proactively spot threats in your environment. They’re often coupled with or part of a broader endpoint security solution that also includes prevention capabilities via an EPP solution to protect against the initial incursion.
As a result, EDR security solutions enable you to protect your organization from sophisticated attacks by rapidly detecting, containing, and remediating threats on your endpoints before they gain a foothold in your environment. They give you deep visibility into your endpoints while effectively identifying both known and unknown threats. Furthermore, you can quickly contain attacks that get through your defenses with automated response capabilities and hunt for hidden threats that are difficult to detect.
While EDR provides several benefits to customers, it has some drawbacks. Chief among them is that EDR security solutions are focused on monitoring endpoints only versus monitoring a broader environment. This means that EDR solutions don’t detect threats targeting other parts of your environment such as your network, email, or cloud infrastructure. In addition, not every organization has the security staff, budget, and/or skills to deploy and run an EDR solution. This is where MEDR solutions come into play.
Managed EDR or MEDR solutions are EDR capabilities delivered as a managed service to customers by third-parties such as cybersecurity vendors or Managed Service Providers (MSPs). This includes key EDR functionality such as monitoring endpoints, detecting advanced threats, rapidly containing threats, and responding to attacks. These third-parties usually have a team of Security Operations Center (SOC) specialists who monitor, detect, and respond to threats across your endpoints around the clock via a ‘follow the sun’ approach to monitoring.
MEDR security solutions allow you to offload the work of securing your endpoints to a team of security professionals. Many organizations need to defend their endpoints from advanced threats but don’t necessarily have the desire, resources, or expertise to manage an EDR solution. In addition, a team of dedicated SOC experts with advanced security tools can typically detect and respond to threats faster than in-house security teams, all while investigating every incident and prioritizing the most critical threats. This enables you to focus on your core business while getting always-on security operations.
Similar to EDR though, one downside to MEDR security solutions is that they defend only your endpoints from advanced threats and don’t monitor other parts of your infrastructure. Moreover, while many organizations want to deploy EDR as a managed service, not everyone desires this. For example, larger and/or more risk-averse organizations who are looking to invest heavily in cybersecurity are typically satisfied with running their own EDR solution. Now, let’s discuss how to choose the right endpoint security solution when trying to defend your endpoints from threats.
As I mentioned in my previous blog, there isn’t a single correct solution for every organization. This logic applies to EDR and MEDR security solutions as well since each solution works well for different types of organizations, depending on their needs, resources, motivations, and more. Nevertheless, one major factor to consider is if you have or are willing to build out a SOC for your organization. This is important because organizations that don’t have or aren’t willing to develop a SOC usually gravitate towards MEDR solutions, which don’t require significant investments in cybersecurity.
Another factor to keep in mind is your security expertise. Even if you’re have or are willing to build a SOC, you may not have the right cybersecurity talent and skills within your organization. While you can always build out your security team, you may want to evaluate an MEDR solution because a lack of expertise makes it difficult to effectively manage an EDR solution. Finally, a common misconception is that you must choose between an EDR and a MEDR solution and that you cannot run both solutions. In reality, many organizations end up using both EDR and MEDR since MEDR solutions often complement EDR deployments.
I hope this information and key factors help you better understand EDR and MEDR solutions while acting as a guide to selecting the best endpoint security solution for your organization. For more details on the different cybersecurity acronyms and how to identify the right solution for your needs, stay tuned for the next blog in this series – Unscrambling Cybersecurity Acronyms: The ABCs of MDR and XDR Security.

A Florida teenager who served as a lackey for a cybercriminal group that specializes in cryptocurrency thefts was beaten and kidnapped last week by a rival cybercrime gang. The teen’s captives held guns to his head while forcing him to record a video message pleading with his crew to fork over a $200,000 ransom in exchange for his life. The youth is now reportedly cooperating with U.S. federal investigators, who are responding to an alarming number of reports of physical violence tied to certain online crime communities.
The grisly kidnapping video has been circulating on a number of Telegram chat channels dedicated to SIM-swapping — the practice of tricking or bribing mobile phone store employees into diverting a target’s phone number, text messages and calls to a device the attackers control.
The teen, known to the SIM-swapping community by the handle “Foreshadow,” appears to have served as a “holder” — a term used to describe a low-level member of any SIM-swapping group who agrees to carry out the riskiest and least rewarding role of the crime: Physically keeping and managing the various mobile devices and SIM cards that are used in SIM-swapping scams.
“Yo, Dan, please bro send the 200k,” Foreshadow said in the video, which was shot on Sept. 15 in the backseat of a moving car. Bleeding from a swollen mouth with two handguns pointed at his head, Foreshadow pleaded for his life. A still shot from that video is available here [Warning: the image is quite graphic].
“They’re going to kill me if you don’t,” Foreshadow continued, offering to get a job as a complicit mobile store employee or “plug” to help with future SIM-swaps. “I’ll pay you back. Just let me know what you need. I got you, for real. Any work for free. Whatever. However long you need me, too. I’ll apply to any store you need me to apply to. I can be a plug. I don’t care if I get caught by the cops or anything. I’ll get that money back for you. I used to do that work.”
It’s not clear where in the world the hostage video was recorded. But at one point in the video, the vehicle’s radio can be heard in the background mentioning WMIB, which is a hip-hop station in South Florida that serves both Ft. Lauderdale and Miami.
As Foreshadow’s hostage video began making the rounds on SIM-swapping Telegram channels, a rumor surfaced that Foreshadow had died after being shot in the leg. It soon emerged that Foreshadow had not died, and that he was cooperating with the Federal Bureau of Investigation (FBI). Members of the SIM-swapping community were then warned to delete any messages to or from Foreshadow. One of those messages read:
JUST IN: FORESHADOW IS NOT DEAD!!!!
HES CURRENTLY CO-OPERATING WITH THE FBI DUE TO HIM BEING KIDNAPPED AND AN ATTEMPT TO EXTORT HIM FOR 200K
IF YOU HAVE CHATS WITH HIM CLEAR THEM
Foreshadow appears to be a teenager from Florida whose first name is Justin. Foreshadow’s main Telegram account was converted from a user profile into a channel on Sept. 15 — the same day he was assaulted and kidnapped — and it is not currently responding to messages.
Foreshadow’s erstwhile boss Jarik told KrebsOnSecurity that the youth was indeed shot by his captors, and blamed the kidnapping on a rival SIM-swapper from Australia who was angry over getting shortchanged of the profits from a previous SIM-swapping escapade.
The FBI did not immediately respond to requests for comment.
Reached via Telegram, the alleged mastermind of the kidnapping — a SIM-swapper who uses the handle “Gus” — confirmed that he ordered the attack on Foreshadow because the holder had held back some of his stolen funds. In the same breath, Gus said Jarik was “gonna get done in next” for sharing Gus’ real name and address with KrebsOnSecurity.
“No1 cared about that nigga anyway, he snaked targs [targets] and flaunted it everywhere,” Gus said of Foreshadow. “I’ve been fucked over so many times I’ve lost millions. I am just a guy trying to make more money.”
Foreshadow’s experience is the latest example of a rapidly escalating cycle of physical violence that is taking hold of criminal SIM-swapping communities online. Earlier this month, KrebsOnSecurity detailed how multiple SIM-swapping Telegram channels are now replete with “violence-as-a-service” offerings, wherein denizens of the underground hire themselves out to perform various forms of physical violence — from slashing tires and throwing a brick through someone’s window, to conducting drive-by shootings, firebombings and home invasions.
On Aug. 12, 2022, 21-year-old Patrick McGovern-Allen of Egg Harbor Township, N.J. was arrested by the FBI and charged with stalking in connection with several of these violence-as-a-service jobs. Prosecutors say the defendant fired a handgun into a Pennsylvania home, and helped to torch another residence in the state with a Molotov Cocktail — all allegedly in service of a beef over stolen cryptocurrency.
Earlier this month, three men in the United Kingdom were arrested for attempting to assault a local man and steal his virtual currencies. The local man’s neighbor called the cops and said the three men were acting suspiciously and that one of them was wearing a police uniform. U.K. police stopped the three men allegedly fleeing the scene, and found a police uniform and weapons in the trunk of the car. All three defendants in that case were charged with “intent to cause loss to another to make an unwarranted demand of Crypto Currency from a person.”
Dina Temple-Raston and Sean Powers over at The Record recently interviewed several members of the SIM-swapping community about this escalation in violence. That story is also available on the Click Here podcast — Throwing Bricks for $$$: Violence-as-a-Service Comes of Age.
