Google Drive and the trouble with the malicious use of cloud applications; a slew of disclosures about state-sponsored campaigns; and a Google Ads-related malvertising issue.
Dark Reading's editors have gathered all of the interesting threat intelligence and cyber-incident stories that we just didn't get to earlier but would feel wrong not covering. In this week's "in case you missed it" (ICYMI) digest, read on for more on the following:
Neopets this week became the third gaming platform in the space of a week to be hit with a cyberattack (after Bandai Namco and Roblox), highlighting the interest that attackers have in hitting "leisure-activity" companies during the summer months. According to reports, the purveyor of virtual pets was robbed for its source code as well as the personal information belonging to its 69 million users.
A hacker who goes by the handle of "TarTarX" is putting the ill-gotten goods up for sale for 4 bitcoins, which translates to around $92,000 using Friday's exchange rate. The stolen PII appears to include data includes members' usernames, names, email addresses, ZIP codes, dates of birth, gender, country, and game-related information.
It's unclear how TarTarX gained access to the website, but Javvad Malik, security awareness advocate at KnowBe4, notes that the attack should be a wake-up call to all consumer-focused enterprises to better secure their data.
“We've seen toy manufacturers and games developers hit in the past due to the vast amount of personal data they collect," he says. "Such organizations should be mindful of the information they gather and the purpose of it. Holding excessive data means greater liability should a breach occur."
Any users impacted by the breach should ensure the password they used for Neopets isn’t used elsewhere, given the potential for credential-stuffing attacks, he adds.
SolarWinds Hackers Embrace Google Drive in Embassy AttacksThe hackers behind the sprawling SolarWinds supply chain attack are at it again, this time abusing Google Drive to smuggle malware onto targets' machines.
The advanced persistent threat (APT), tracked as APT29, Cloaked Ursa, Cozy Bear, or Nobellium, launched two waves of email-borne attacks between May and June. According to an analysis from Palo Alto Networks' Unit 42, the attacks targeted a foreign embassy in Portugal and another in Brazil. The group used a supposed agenda for an upcoming meeting with an ambassador as a lure.
"In both cases, the phishing documents contained a [Google Drive] link to a malicious HTML file (EnvyScout) that served as a dropper for additional malicious files in the target network, including a Cobalt Strike payload," according to Unit 42's post this week.
APT29 is believed by the US government to be affiliated with Russia’s Foreign Intelligence Service (SVR), and is widely considered to be responsible not only for SolarWinds but also the hack of the United States Democratic National Committee (DNC) in 2016.
The use of legitimate cloud services to deliver malicious payloads is on the rise as cybercriminals look to take advantage of the entrenched trust that millions of business users (and email gateways) have in them. Lior Yaari, CEO and co-founder of Grip Security, noted that this points to the need to better vet content coming from software-as-a-service (SaaS) app.
“The recent malicious activity discovered using Google Drive is emblematic of the SaaS security challenge — universal accessibility and ease of deployment," he said in a statement to Dark Reading. "Before Google Drive, there was Dropbox and before Dropbox, APT29 was hitting Microsoft 365. The SaaS security challenge for campaigns like these only illustrates the trend toward exploiting SaaS’s strengths for nefarious ends. And the matter only becomes worse with more SaaS out-of-sight for many security teams.”
Nation-State Attacks Ramp Up in APT-a-PaloozaSpeaking of APTs, several nation-state-backed campaigns came to light this week. For instance, Citizen Lab said that it had forensically confirmed that at least 30 individuals were infected with NSO Group’s Pegasus mobile spyware after an extensive espionage campaign that took place late last year. The effort targeted Thai pro-democracy protesters and activists calling for reforms to the monarchy.
Google's Threat Analysis Group for its part flagged an odd false-flag operation in Ukraine. The Russia-linked hacking group Turla (aka Snake, Uroburos, and Venomous Bear) have created a malicious Android app that masquerades as a tool for Ukrainian hackers looking to carry out distributed denial-of-service (DDoS) attacks against Russian websites. Turla dubbed the app CyberAzov, in reference to the Azov Regiment or Battalion, a far-right group that has become part of Ukraine’s national guard.
CyberAzov is "hosted on a domain controlled by the actor and disseminated via links on third party messaging services," according to Google TAG. While the app is distributed under the guise of performing DDoS attacks, "the 'DoS' consists only of a single GET request to the target website, not enough to be effective."
In reality, the app is "designed to map out and figure out who would want to use such an app to attack Russian websites," according to an additional commentary from Bruce Schneier.
Meanwhile, Cisco Talos observed an unusual campaign targeting Ukrainian entities, which it said is likely attributable to Russia. This attack stood out amidst the barrage of cyberattacks that have been mounted against Ukraine, researchers said, because the attack targeted a large software development company whose wares are used in various state organizations within Ukraine.
"As this firm is involved in software development, we cannot ignore the possibility that the perpetrating threat actor's intent was to gain access to source a supply chain-style attack," researchers said in a posting this week, adding that the persistent access could also have been leveraged in other ways, including gaining deeper access into the company's network or launching additional attacks such as ransomware.
Also notable is the fact the effort revolved around "a fairly uncommon piece of malware" called GoMet; GoMet is an open source backdoor that was first seen in the wild in March.
And finally, the government of Belgium issued a statement disclosing a spate of attacks against its defense sector and public safety organizations emanating from three China-linked threat groups: APT27, APT30, and APT31 (aka Gallium or UNSC 2814).
The "malicious cyber activities … significantly affected our sovereignty, democracy, security and society at large by targeting the FPS Interior and the Belgian Defence," according to the statement.
Google Ads Abused as Part of Tech Support ScamsPeople performing a Google search for Amazon, Facebook, YouTube, or Walmart could find themselves browser-hijacked, researchers warned this week.
A malvertising campaign is abusing Google’s ad network to redirect visitors to an infrastructure of tech support scams, according to Malwarebytes.
"The threat actors are … purchasing ad space for popular keywords and their associated typos," researchers explained in a posting. "A common human behavior is to open up a browser and do a quick search to get to the website you want without entering its full URL. Typically a user will (blindly) click on the first link returned (whether it is an ad or an organic search result)."
In Google search results, those first returned links could be ads that redirect users to fake warnings urging them to call rogue Microsoft agents for support, researchers explained.
"Victims were simply trying to visit those websites and relied on Google Search to take them there. Instead, they ended up with an annoying browser hijack trying to scam them," researchers lamented.
The approach could just as easily be used to redirect to malicious sites serving up malware or phishing pages, researchers noted. Users — especially business users — should always take care to be skeptical when unexpected browser redirects occur.
Cyber insurers need to tread lightly when using cyber security rating scores — also known as outside-in security-risk assessments — because the data can be skewed and may mislead consumers into believing they’re more protected than they really are, said one cyber insurer.
Cyber security ratings provide an “outside-in” view of a company’s overall cybersecurity posture by giving the client a rating similar to a credit score. Score rating ranges can be expressed by numbers up to 100 or 1,000, or letter grades from A to D, where a higher rating indicates a better security posture.
These rating systems emerged in the early 2000s, said Lindsey Nelson, cyber development leader at CFC Underwriting in a webinar.
“They took off because they took a highly technical area and simplified it for company owners who found a simple score much easier to understand than a long list of strange sounding assets and vulnerabilities.”
But while these cyber ratings have noble goals, they also have potential to prove troublesome for cyber insurers.
“Lots of security professionals still struggle with cyber ratings because they can be misleading, and that’s because the quality of the ratings are completely dependent on the data used to produce them. And that data is often limited,” said Nelson.
For example, if a small company outsources the hosting of their servers to cloud computing providers like Microsoft or Amazon Web Services, the security scan may not be able to detect all parts of the network, Nelson said.
“Our cybersecurity score could be telling us that the client is a 99 out of 100, based on the assets that I can see, but there is a load of assets that it can’t see which may or may not be secure.” This could potentially lead a small business owner into a “false sense of security,” Nelson said.
Conversely, the rating may display a false negative or positive score. “It might release a low score for a company that’s actually got excellent controls, which might raise questions around credibility if it’s not explained properly,” Nelson added.
What’s more, some clients may rely too heavily on their cyber ratings when making business decisions.
“We’ve seen the narrative shift around cyber ratings, [from] ‘this is a tool which can be useful in identifying some of your vulnerabilities,’ to ‘this score is the [ultimate] authority on how secure you as an organization are,’ and…how likely you are to have a claim is dependent solely on this score.’”
To mitigate these problems, cyber insurers need to be upfront with clients about the limitations of cyber ratings.
“We just need to be really careful as a market that we don’t start claiming authority or predicting outcomes based on skewed data sets that we don’t really understand,” said Nelson. “And we need to be totally transparent with customers about what it is that we’re presenting them.”
