White House Announces Possible Rise in Cyberattacks—What You Can Do to Stay Safe

By McAfee

The White House recently reissued a warning to American businesses in response to the unprecedented economic sanctions the U.S. has imposed on Russia for the Ukraine invasion, stating, “There is now evolving intelligence that Russia may be exploring options for potential cyberattacks.”  

Along with this statement, the White House published a fact sheet outlining the new and ongoing steps the government is taking to protect its infrastructure and technologies, along with steps that private businesses can take to protect themselves from attacks as well.  

Of course, any successful attack on government operations and the operations of private businesses could potentially affect households as well—such as in the case of data breaches where data or information is stolen from a system, often the personal data and information of individuals. 

Word of potential attacks understandably leaves people feeling uncertain and may further leave them wondering if there’s anything they can do to protect themselves. With regards to data breaches and the cases of identity theft that typically follow, there are several steps people can take to keep safer online.  

Let’s break down what a data breach looks like, how it can affect you, and what you can do in advance of a breach to protect yourself. 

Examples of data breaches in the past 

We’ve certainly seen data breaches make the news over the years, which are often (but not always) associated with malicious hackers or hacker organizations. A quick list of some of the largest and most impactful breaches we’ve seen in recent years: 

  • Facebook – 2019: Two datasets leaked the records of more than 530 million users, including phone numbers, account names, Facebook IDs, and more. 
  • Marriott International (Starwood) – 2018. Leakage of 500,000 guest names, emails, actual mailing addresses, phone numbers, passport numbers, Starwood Preferred Guest account information, date of birth, and information about stays. 
  • Equifax – 2017. Approximately 147 million records, including name, address, date of birth, driver’s license numbers, and Social Security Numbers were leaked, as well as credit card information for a further 200,000 victims. 

Healthcare facilities have seen their data breached, along with the operations of popular restaurants. Small businesses find themselves in the crosshairs as well, with one report stating that 43% of data leaks target small businesses. Those may come by way of an attack on where those businesses store their records, a disgruntled employee, or by way of a compromised point-of-sale terminal in their store, office, or location. 

What differs with the White House warning is who may end up being behind these potential attacks—a nation-state rather than what are financially motivated hackers or hacking groups. (Some research indicates that nearly 90% of breaches are about the money.) However, the result is the same. Your personal information winds up loose in the world and possibly in the hands of a bad actor.   

What can get exposed in a data breach?  

The fact is that plenty of our information is out there on the internet, simply because we go about so much of our day online, whether that involves shopping, banking, getting results from our doctors, or simply hopping online to play a game once in a while.  

Naturally, that means the data in any given breach will vary from service to service and platform to platform involved. Certainly, a gaming service will certainly have different information about you than your insurance company. Yet broadly speaking, there’s a broad range of information about you stored in various places, which could include:  

  • Username and password 
  • E-mail address 
  • Phone numbers and home address 
  • Contact information of friends and family 
  • Date of birth 
  • Driver’s license number 
  • Credit card and debit card numbers, bank account details 
  • Purchase history and account behavior history 
  • Patient information (in the case of healthcare breaches) 
  • Social Security Number or Tax ID Number 

As to what gets exposed and when you might find out about it, that can vary greatly as well. One industry research report found that 60% of breaches were discovered in just days from the initial attack while others could take months or even longer detect. Needless to say, the timeline can get rather stretched before word reaches you, which is a good reason to change your passwords regularly should any of them get swept up in a breach. (An outdated password does a hacker no good—more on that in a bit.) 

What do cybercriminals do with this kind of information? 

The answer is plenty. In all, personal information like that listed above has a dollar value to it. In a way, your data and information are a kind of currency because they’re tied to everything from your bank accounts, investments, insurance payments—even tax returns and personal identification like driver’s licenses.  

With this information in hand, a crook can commit several types of identity crimes—ranging from fraud to theft. In the case of fraud, that could include running up a bill on one of your credits cards or draining one of your bank accounts. In the case of theft, that could see crooks impersonate you so they can open new accounts or services in your name. Beyond that, they may attempt to claim your tax refund or potentially get an ID issued in your name as well. 

Another possibility is that a hacker will simply sell that information on the dark marketplace, perhaps in large clumps or as individual pieces of information that go for a few dollars each. However it gets sold, these dark-market practices allow other fraudsters and thieves to take advantage of your identity for financial or another gain.  

Protecting yourself from the effects of data breaches 

The succinct answer is to sign up for an identity protection service. It can monitor dozens of types of personal information and then alert you if any of them are possibly being misused, so you can address any issues right away before they become a potentially much bigger problem.  

Further, pairing identity protection with online protection software can protect you even more. With an all-up view of your overall online security—how well you’re protecting yourself and your identity online—it can guide you through steps that can shore up your protection and make you safer still. 

Identity protection such as ours gives you the added benefit of a professional recovery specialist who can assist with restoring your affairs in the wake of fraud or theft, plus up to $1 million in insurance coverage. 

What if I think I’m the victim of identity theft? 

When a business, service, or organization falls victim to a breach, it doesn’t always mean that you’re automatically a victim too. Your information may not have been caught up in it. However, it’s best to act as if it was. With that, we strongly suggest you take these immediate steps. 

Change your passwords and use two-factor authentication 

Given the possibility that your password may be in the hands of a bad actor, change it right away. Strong, unique passwords offer one of your best defenses against hackers. Update them regularly as well. As mentioned above, this can protect you in the event a breach occurs and you don’t find out about it until well after it’s happened. You can spare yourself the upkeep that involves a password manager that can keep on top of it all for you. If your account offers two-factor authentication as part of the login process, make use of it as it adds another layer of security that makes hacking tougher.  

Keep an eye on your accounts 

If you spot unusual or unfamiliar charges or transactions in your account, bank, or debit card statements, follow up immediately. That could indicate improper use. In general, banks, credit card companies, and many businesses have countermeasures to deal with fraud, along with customer support teams that can help you file a claim if needed. 

Sign up for an identity theft protection service 

As outlined above, identity protection like ours can monitor a broad set of your personal information and provide you guidance for making it more secure, in addition to getting help from a professional recovery specialist.  

For an even closer look at identity theft, we have two articles that can help guide the way if you think you’re a victim, each featuring a series of straightforward steps you can take to set matters right: 

Proactively protecting yourself and your family 

No matter how uncertain news of possible cyberattacks may any of us feel, you can take steps to set some of that uncertainty aside. An identity protection service is a strong first move against possible identity theft, as is pairing it with online protection software that keeps you safer online overall. Likewise, knowing the signs of possible identity theft and what you can do to address it right away offer further assurance still—like having the services of a professional recovery specialist to help.  

In all, there’s no need to leave yourself wondering at the news from the White House. As an individual, you have it in your power to make yourself and your family safer than they are now.

Costa Rica May Be Pawn in Conti Ransomware Group’s Bid to Rebrand, Evade Sanctions

By BrianKrebs

Costa Rica’s national health service was hacked sometime earlier this morning by a Russian ransomware group known as Hive. The intrusion comes just weeks after Costa Rican President Rodrigo Chaves declared a state of emergency in response to a data ransom attack from a different Russian ransomware gang — Conti. Ransomware experts say there is good reason to believe the same cybercriminals are behind both attacks, and that Hive has been helping Conti rebrand and evade international sanctions targeting extortion payouts to cybercriminals operating in Russia.

The Costa Rican publication CRprensa.com reports that affected systems at the Costa Rican Social Security Fund (CCSS) were taken offline on the morning of May 31, but that the extent of the breach was still unclear. The CCSS is responsible for Costa Rica’s public health sector, and worker and employer contributions are mandated by law.

A hand-written sign posted outside a public health center in Costa Rica today explained that all systems are down until further notice (thanks to @Xyb3rb3nd3r for sharing this photo).

A hand-written notice posted outside a public health clinic today in Costa Rica warned of system outages due to a cyberattack on the nation’s healthcare systems. The message reads: “Dear Users: We would like to inform you that due a problem related to the information systems of the institution, we are unable to expend any medicine prescriptions today until further notice. Thank you for your understanding- The pharmacy.”

Esteban Jimenez, founder of the Costa Rican cybersecurity consultancy ATTI Cyber, told KrebsOnSecurity the CCSS suffered a cyber attack that compromised the Unique Digital Medical File (EDUS) and the National Prescriptions System for the public pharmacies, and as a result medical centers have turned to paper forms and manual contingencies.

“Many smaller health centers located in rural areas have been forced to close due to not having the required equipment or communication with their respective central health areas and the National Retirement Fund (IVM) was completely blocked,” Jimenez said. “Taking into account that salaries of around fifty thousand employees and deposits for retired citizens were due today, so now the payments are in danger.”

Jimenez said the head of the CCSS has addressed the local media, confirming that the Hive ransomware was deployed on at least 30 out of 1,500 government servers, and that any estimation of time to recovery remains unknown. He added that many printers within the government agency this morning began churning out copies of the Hive ransom note.

“HIVE has not yet released their ransom fee but attacks are expected to follow, other organizations are trying to get a hold on the emergency declaration to obtain additional funds to purchase new pieces of infrastructure, improve their backup structure amongst others,” Jimenez said.

A copy of the ransom note left behind by the intruders and subsequently uploaded to Virustotal.com indicates the CCSS intrusion was the work of Hive, which typically demands payment for a digital key needed to unlock files and servers compromised by the group’s ransomware.

On May 8, President Chaves used his first day in office to declare a national state of emergency after the Conti ransomware group threatened to publish gigabytes of sensitive data stolen from Costa Rica’s Ministry of Finance and other government agencies. Conti initially demanded $10 million, and later doubled the amount when Costa Rica refused to pay. On May 20, Conti leaked more than 670 gigabytes of data taken from Costa Rican government servers.

As CyberScoop reported on May 17, Chaves told local media he believed that collaborators within Costa Rica were helping Conti extort the government. Chaves offered no information to support this claim, but the timeline of Conti’s descent on Costa Rica is worth examining.

Most of Conti’s public communications about the Costa Rica attack have very clearly assigned credit for the intrusion to an individual or group calling itself “unc1756.” In March 2022, a new user by the same name registered on the Russian language crime forum Exploit.

A message Conti posted to its dark web blog on May 20.

On the evening of April 18, Costa Rica’s Ministry of Finance disclosed the Conti intrusion via Twitter. Earlier that same day, the user unc1756 posted a help wanted ad on Exploit saying they were looking to buy access to “special networks” in Costa Rica.

“By special networks I mean something like Haciendas,” unc1756 wrote on Exploit. Costa Rica’s Ministry of Finance is known in Spanish as the “Ministerio Hacienda de Costa Rica.” Unc1756 said they would pay $USD 500 or more for such access, and would work only with Russian-speaking people.

THE NAME GAME DISTRACTION

Experts say there are clues to suggest Conti and Hive are working together in their attacks on Costa Rica, and that the intrusions are tied to a rebranding effort by Conti. Shortly after Russia invaded Ukraine at the end of February, Conti declared its full support, aligning itself directly with Russia and against anyone who would stand against the motherland.

Conti’s threatening message this week regarding international interference in Ukraine.

Conti quickly deleted the declaration from its website, but the damage had already been done, and any favor or esteem that Conti had earned among the Ukrainian cybercriminal underground effectively evaporated overnight.

Shortly thereafter, a Ukrainian security expert leaked many months worth of internal chat records between Conti personnel as they plotted and executed attacks against hundreds of victim organizations. Those candid messages exposed what it’s like to work for Conti, how they undermined the security of their targets, as well as how the group’s leaders strategized for the upper hand in ransom negotiations.

But Conti’s declaration of solidarity with the Kremlin also made it increasingly ineffective as an instrument of financial extortion. According to cyber intelligence firm ADVIntel, Conti’s alliance with the Russian state soon left it largely unable to receive ransom payments because victim companies are being advised that paying a Conti ransom demand could mean violating U.S. economic sanctions on Russia.

“Conti as a brand became associated with the Russian state — a state that is currently undergoing extreme sanctions,” ADVIntel wrote in a lengthy analysis (PDF). “In the eyes of the state, each ransom payment going to Conti may have potentially gone to an individual under sanction, turning simple data extortion into a violation of OFAC regulation and sanction policies against Russia.”

Conti is by far the most aggressive and profitable ransomware group in operation today. Image: Chainalysis

ADVIntel says it first learned of Conti’s intrusion into Costa Rican government systems on April 14, and that it has seen internal Conti communications indicating that getting paid in the Costa Rica attack was not the goal.

Rather, ADVIntel argues, Conti was simply using it as a way to appear publicly that it was still operating as the world’s most lucrative ransomware collective, when in reality the core Conti leadership was busy dismantling the crime group and folding themselves and top affiliates into other ransomware groups that are already on friendly terms with Conti.

“The only goal Conti had wanted to meet with this final attack was to use the platform as a tool of publicity, performing their own death and subsequent rebirth in the most plausible way it could have been conceived,” ADVIntel concluded.

ADVIntel says Conti’s leaders and core affiliates are dispersing to several Conti-loyal crime collectives that use either ransomware lockers or strictly engage in data theft for ransom, including AlphV/BlackCat, AvosLocker, BlackByte, HelloKitty, Hive, and Karakurt.

Still, Hive appears to be perhaps the biggest beneficiary of any attrition from Conti: Twice over the past week, both Conti and Hive claimed responsibility for hacking the same companies. When the discrepancy was called out on Twitter, Hive updated its website to claim it was not affiliated with Conti.

Conti and Hive’s Costa Rican exploits mark the latest in a string of recent cyberattacks against government targets across Latin America. Around the same time it hacked Costa Rica in April, Conti announced it had hacked Peru’s National Directorate of Intelligence, threatening to publish sensitive stolen data if the government did not pay a ransom.

But Conti and Hive are not alone in targeting Latin American victims of late. According to data gathered from the victim shaming blogs maintained by multiple ransomware groups, over the past 90 days ransom actors have hacked and sought to extort 15 government agencies in Brazil, nine in Argentina, six in Colombia, four in Ecuador and three in Chile.

A recent report (PDF) by the Inter-American Development Bank suggests many Latin American countries lack the technical expertise or cybercrime laws to deal with today’s threats and threat actors.

“This study shows that the Latin American and Caribbean (LAC) region is not sufficiently prepared to handle cyberattacks,” the IADB document explains. “Only 7 of the 32 countries studied have a critical infrastructure protection plan, while 20 have established cybersecurity incident response teams, often called CERTs or CSIRTs. This limits their ability to identify and respond to attacks.”
