State-Sponsored Hackers Steal FireEye Red Team Security Testing, Assessment Tools

 State-sponsored hackers have attacked FireEye and stolen the cybersecurity company’s Red Team penetration testing and assessment tools, FireEye disclosed in an SEC filing on December 8, 2020. FireEye is concerned the hackers will potentially use the stolen Red Team penetration testing tools to attack additional companies. As a precaution, the company is sharing countermeasures to help potential targets mitigate attacks.

The Cybersecurity and Infrastructure Security Agency (CISA), part of the U.S. Department of Homeland Security, issued this warning about the stolen FireEye tools.

FireEye CEO Kevin Mandia

Among the key FireEye disclosures in the SEC filing:

1. State Sponsored Actor?: The attacker was a “highly sophisticated cyber threat actor” whose “discipline, operational security, and techniques lead us to believe it was a state-sponsored attack.” CEO Kevin Mandia believes the atack involves a “nation with top-tier offensive capabilities.”

2. FireEye Tools Were the Specific Target: This attack specifically targeted FireEye, and used methods that “counter security tools and forensic examination.” Hackers attacked “used a novel combination of techniques not witnessed by us or our partners in the past.” The attacker targeted and accessed certain Red Team assessment tools that FireEye uses to test our customers’ security.

3. FBI, Microsoft Assist Investigation: FireEye is investigating the attack in coordination with the Federal Bureau of Investigation and other key partners, including Microsoft.

4. Defending Against the Red Team Tools: FireEye is proactively “releasing methods and means to detect the use of our stolen Red Team tools.” The company doesn’t know if the attacker intends to use the Red Team tools or to publicly disclose them. FireEye has developed more than 300 countermeasures for customers and the community at large to use in order to minimize the potential impact of the theft of these tools.

5. No Additional Attacks So Far: FireEye has seen no evidence to date that any attacker has used the stolen Red Team tools, but continues to monitor for their use.

6. Customer Information Targeted, But Not Stolen: The attacker primarily sought information related to certain government customers. While the attacker was able to access some of FireEye’s internal systems, there’s no evidence (so far) that the attacker exfiltrated data from the company’s customer information, incident response or consulting engagements or the metadata collected by products in the dynamic threat intelligence systems. FireEye plans to contact customers directly if it discovers any information was detected.

7. More Details: If/when more details become available, FireEye will disclose the information via its corporate blog.

Visa Warns of Fresh Skimmer Targeting E-Commerce Sites

 

Visa Warns of Fresh Skimmer Targeting E-Commerce Sites

Visa's payment fraud disruption team is warning of a recently uncovered digital skimmer called "Baka" that is stealing payment card data from e-commerce sites while hiding from security tools.

Researchers discovered the malicious code while examining a command-and-control infrastructure that previously hosted the ImageID skimmer.

Although Baka functions similarly to other JavaScript skimmers, the Visa fraud team found that this malicious code is able to load dynamically into e-commerce sites and then hide from security tools using obfuscation techniques, according to the Visa alert.

The Baka skimmer has been found in "several merchant websites across multiple global regions," the alert notes, but it does not provide further details.

"The most compelling components of this kit are the unique loader and obfuscation method," the Visa alert notes. "The skimmer loads dynamically to avoid static malware scanners and uses unique encryption parameters for each victim to obfuscate the malicious code. ... This skimmer variant avoids detection and analysis by removing itself from memory when it detects the possibility of dynamic analysis with developer tools or when data has been successfully exfiltrated."

How Baka Works

The Visa alert does not indicate how Baka is initially delivered to a network. But the report notes that the malicious code is hosted on several suspicious domains, including: jquery-cycle[.]com, b-metric[.]com, apienclave[.]com, quicdn[.]com, apisquere[.]com, ordercheck[.]online and pridecdn[.]com.

Once the initial infection takes hold, the skimmer is uploaded through the command-and-control server, but the code loads in memory. This means the malware is never present on the targeted e-commerce firm's server or saved to another device, helping it to avoid detection, according to the alert.

"The skimming payload decrypts to JavaScript written to resemble code that would be used to render pages dynamically," according to Visa.

Once embedded in an e-commerce site's checkout page, the skimmer begins to collect payment and other customer data from various fields and sends the information to the fraudsters' command-and-control server, Visa notes.

Once data exfiltration is complete, Baka performs a "clean-up" function that removes the skimming code from the checkout page, according to the alert. This also helps ensure that JavaScript is not spotted by anti-malware tools.

Visa's analysts found that the operators behind Baka use an XOR cipher as a way to obscure the malicious code and further hide it from detection, according to the alert.

"While the use of an XOR cipher is not new, this is the first time Visa has observed its use in JavaScript skimming malware," according to the alert.

Mitigating risks

The Visa alert advises e-commerce merchants to take several steps to mitigate skimming risks, including:

  • Run regular checks to determine if any code is attempting to communicate with a known command-and-control server;
  • Check code added through a service provider;
  • Vet content delivery networks and other third parties that have access to the checkout function;
  • Update and patch any software or services used on checkout sites and consider adding a firewall;
  • Limit access to online administrative portals and ensure that those with access use strong passwords.

Other Skimming Attacks

In November 2019, Visa researchers uncovered another type of skimmer called Pipka that had the ability to remove itself from the HTML of a compromised payment website after it executed, enabling it to avoid security detection (see: New JavaScript Skimmer Found on E-Commerce Sites).

Other security researchers have more recently warned about ongoing attacks against e-commerce websites using malicious JavaScript to steal payment card data.

For example, in August, security firm Group-IB warned of a cybercriminal gang called "UltraRank" that is using malicious code to skim payment card data and then selling that information to others on its own underground site (see: 'UltraRank' Gang Sells Card Data It Steals).

Earlier this month, security firm Malwarebytes warned that some fraudsters have started using encrypted messages on Telegram to steal data faster (see: Fraudsters Use Telegram App to Steal Payment Card Data).

BREAKING: Alleged Twitter Hacker Arrested

The alleged Twitter hacker has been arrested, The Wall Street Journal reports. Graham Ivan Clark, of Tampa, was arrested and charged as an adult on July 31, 2020. Clark faces 30 felony charges related to the hack, the report says.
The Twitter hack affected multiple celebrity and public official accounts, and tricked users into sending bitcoin to hackers. The Twitter attack raises serious economic, financial, political and national security concerns ahead of the 2020 U.S. Presidential Election.
How was Twitter security breached, who got hacked and what steps will the social media company take to further strengthen its platform? Here’s a regularly updated blog tracking the incident, Twitter’s investigation and corrective measures, and the high-stakes effort to keep social media secure.
Note: Blog originally published on July 16, 2020. Updated regularly thereafter with the latest investigation news.

Twitter Statements About Security Incident

In a July 18, 2020 statement about the security incident, Twitter indicated:
  • attackers targeted certain Twitter employees through a social engineering scheme.
  • The attackers successfully manipulated a small number of employees and used their credentials to access Twitter’s internal systems, including getting through two-factor protections.
  • 130 Twitter accounts were targeted.
  • For 45 of those accounts, the attackers were able to initiate a password reset, login to the account, and send Tweets.
  • For up to eight of the Twitter accounts involved, the attackers took the additional step of downloading the account’s information through our “Your Twitter Data” tool.
  • Twitter’s incident response team secured and revoked access to internal systems to prevent the attackers from further accessing the systems and the individual accounts.
  • For the 130 accounts that were targeted, attackers were not able to view previous account passwords, as those are not stored in plain text or available through the tools used in the attack. Attackers were able to view personal information including email addresses and phone numbers, which are displayed to some users of our internal support tools. In cases where an account was taken over by the attacker, they may have been able to view additional information. Our forensic investigation of these activities is still ongoing.

  • Which Twitter Accounts Got Hijacked?: The accounts of U.S. presidential candidate Joe Biden, reality TV star Kim Kardashian, former U.S. President Barack Obama, Tesla and Space-X founder Elon Musk, and Microsoft co-founder Bill Gates were allegedly victimized. SourceReuters, July 15, 2020.
  • How Many Twitter Accounts Were Victimized?: Hackers targeted about 130 accounts during the cyber attack this week. Twitter continues to assess whether the attackers were able to access private data of the targeted accounts. SourceReuters, July 16, 2020.
  • What did Twitter Initially Say About the Security Incident?: Twitter’s security account posted around 5:45 p.m. EDT on July 15, 2020 that the company was investigating the incident and taking steps to rectify it. Within roughly a half hour, the company took the extraordinary step of limiting posts from verified accounts with blue check marks, which Twitter generally designates for more prominent users. Twitter, late July 15, said it believed the hackers perpetrated the attack by targeting employees who had access to the company’s internal systems and tools. The hackers may have accessed information or engaged in other malicious activity, Twitter said, adding it was still investigating the incident. The company didn’t say how long the hackers had been able to access its internal systems. Twitter said it had limited access to internal systems in response to the hack and locked compromised accounts. SourceThe Wall Street Journal, July 15, 2020.
  • How is the U.S. Government Investigating the Twitter Hack?: The FBI’s San Francisco office has launched an investigation into the incident. SourceReuters, July 16, 2020.

Twitter Hacked: The Bigger Concerns

  • Why Should MSSPs Care?: At first, there was  concern that Twitter hackers may have bypassed two-factor authentication (2FA) security settings. But now, the concern has shifted to how hackers allegedly gained control of Twitter’s administration tool(s). Similarly, MSSP administration tools — including remote control and remote access software — have been popular hacker targets for infiltrating end-customer systems.
  • Why Are Regulators Concerned?: The Twitter breach raises serious questions and concerns — especially ahead of the 2020 U.S. Presidential Election. Hackers who gain control of social media administration tools can, in theory, spread misinformation that potentially manipulates financial markets, elections, international relations, protests, and overall confidence in political systems.
This remains a developing story. Check back for ongoing updates about the breach.
