Data Leaks & Breaches

Leaks & Breaches
Company Information Affected
Cardpool (US) Researchers at Gemini Advisory reported that in February 2021 a cybercriminal actor sold 330,000 stolen payment cards which they linked back to the now defunct gift card exchange service. The criminal also sold 895,000 stolen gift cards; the researchers assess with moderate confidence that these also came from Cardpool. The gift cards were for well known companies such as Amazon, Nike, Target, and American Airlines. The breach likely occurred between February 4th and August 4th, 2019. Unknown
Administrative Advantage (US) The company, which provides billing support services to healthcare providers, discovered that an unauthorised individual may have accessed an employee email account between June 23rd and July 9th, 2020.

Facebook (US) Mobile numbers, names, dates of birth, email addresses, and more, were freely shared on a hacker forum. The data, which was allegedly harvested in 2019, was previously sold for a reported price of $30,000 in June 2020. Alon Gal of Hudson Rock stated that the threat actor likely gained the mobile numbers via a flaw in Facebook’s ‘Add Friend’ feature which was patched in 2019. 533,313,128

Industry Information
Technology Onapsis and SAP released a joint alert and report detailing active exploitation attempts of unprotected SAP applications. The companies noted that patches for the exploited vulnerabilities have been available for months, and in some cases years, yet many organisations have failed to apply the proper mitigations. Organisations are advised to apply SAP patches and secure configurations immediately.
Government A spokesperson for the European Commission announced that the commission and several other European Union (EU) organisations were targeted by a cyberattack in March 2021 which impacted IT infrastructure. Although details are scant at present, an anonymous source who is familiar with the matter informed Bloomberg that the attack was bigger than standard cyberattacks that regularly target the EU. The source also said that the severity of the attack was high enough that senior commission officials were alerted.
Banking & Finance Researchers at ESET found that the Janeleiro banking trojan has been targeting corporate users in Brazil since 2019. The attacks start via phishing emails which have been sent to targets in a range of sectors, including engineering, government, finance, healthcare, and manufacturing. Janeleiro uses pop-up windows that imitate the biggest banks in Brazil and attempt to get users to enter their personal information which is sent to the attackers’ C2.
Retail & Tourism VISA reported that throughout 2020 they increasingly saw JavaScript-based credit card skimming scripts injected into hacked online web stores via web shells. The skimmers allow attackers to steal payment and personal data belonging to shoppers. The web shells were predominantly used by Magecart threat actors to backdoor hacked online store servers. The company stated that at least 45 skimming attacks in 2020 used web shells. The trend reportedly mirrors a rise in the use of web shells across the wider threat landscape.
Cryptocurrency Security researcher Justin Perdok identified attackers using GitHub Actions to mine for cryptocurrency. The attack, which targets GitHub repositories, begins with the threat actor forking a legitimate repository that uses GitHub Actions. The attacker then injects malicious code into the forked version and merges the code back to the original repository maintainers by filing a Pull Request. The original project maintainer does not have to approve the Pull Request. At least 95 repositories were targeted by the threat actor who sought to deliver a cryptominer hosted on GitLab. A copycat attack spotted by security researcher Mark Dodgson impacted over 50 legitimate repositories. BleepingComputer found a variation of this attack pulling the open-source XMRig cryptominer from XMRig’s official GitHub repository.
