Cybersecurity news

  • The Cybersecurity and Infrastructure Security Agency has added the Zimbra CVE-2022-27824 flaw to its ‘Known Exploited Vulnerabilities Catalog,’ indicating that it is actively exploited in attacks by hackers. This high-severity vulnerability allows an unauthenticated attacker to steal email account credentials in cleartext form from Zimbra Collaboration instances without user interaction.
  • Researchers at Trellix have discovered a critical unauthenticated remote code execution vulnerability impacting 29 models of the DrayTek Vigor series of business routers. The attacker does not need credentials or user interaction to exploit the vulnerability, with the default device configuration making the attack viable via the internet and LAN.
  • Security researchers have discovered a new vulnerability called ParseThru affecting Golang-based applications that could be abused to gain unauthorized access to cloud-based applications. The issue has to do with inconsistencies stemming from changes introduced to Golang’s URL parsing logic that’s implemented in the “net/url” library.
  • No More Ransom, the initiative launched to help victims of ransomware decrypt their files, celebrates its six-year anniversary. Since the launch, it has grown from four partners to 188 and has contributed 136 decryption tools covering 165 ransomware families. In doing so, it has helped more than 1.5 million people decrypt their devices all over the world – with the project available in 37 languages.
  • A new phishing as a service platform named ‘Robin Banks’ has been launched, offering ready-made phishing kits targeting the customers of well-known banks and online services. The targeted entities include Citibank, Bank of America, Capital One, Wells Fargo, PNC, U.S. Bank, Lloyds Bank, the Commonwealth Bank in Australia, and Santander. Additionally, Robin Banks offers templates to steal Microsoft, Google, Netflix, and T-Mobile accounts.
  • Microsoft says attackers increasingly use malicious Internet Information Services web server extensions to backdoor unpatched Exchange servers as they have lower detection rates compared to web shells. Because they’re hidden deep inside the compromised servers and often very hard to detect being installed in the exact location and using the same structure as legitimate modules, they provide attackers’ with a perfect and durable persistence mechanism.
