Universities Targeted in Silent Librarian Spear Phishing Campaign
The Iran-based hacking group known as Silent Librarian – aka Cobalt Dickens and TA407 – has recommenced spear phishing attacks on universities in the United States and around the world. The hacking group has been conducting attacks since 2013 to gain access to login credentials and steal intellectual property and research data. Credentials and data stolen in the attacks are subsequently sold via the hacking group’s portals. The U.S. Department of Justice indicted 9 Iranians in connection with the attacks in 2018, but the indictments have had no effect on the campaigns which have continued. Those individuals have yet to be brought to justice. The spear phishing campaigns usually recommence in September to coincide with the start of the new academic year. The hackers have developed many different phishing websites which are used in the campaigns, and while many of these sites are taken down, sufficient numbers are used to ensure the campaigns can continue. This year, the group is known to be using sites hosted in Iran, which could hamper efforts to have the sites shut down due...
Patch Wormable ‘Bad Neighbor’ Windows TCP/IP Flaw Now, Warns CISA
On October 2020 Patch Tuesday, Microsoft released a patch to correct a critical remove code execution vulnerability in the Microsoft Windows Transmission Control Protocol (TCP)/IP stack. The flaw concerns how the TCP/IP stack handles Internet Control Message Protocol version 6 (ICMPv6) Router Advertisement packets. The flaw was assigned a CVSS v3 score of 9.8 out of 10. While all patches should be applied promptly to prevent exploitation, there is usually a delay between patches being released and exploits being developed and used offensively against organizations; however, due to the severity of the flaw and the ease at which it can be exploited, patching this vulnerability is especially important. So much so that the Department of Homeland Security Cybersecurity and Infrastructure Security Agency (CISA) took to Twitter to urge all organizations to apply the patch immediately. An attacker could exploit the flaw remotely in a Denial of Service attack, resulting in a ‘blue screen of death’ system crash; however, exploitation could also allow the remote execution of arbitrary code on...
Piedmont Cancer Institute Phishing Attack Impacts 5,000 Patients
Piedmont Cancer Institute (PCI) in Atlanta, GA is notifying 5,226 patients that some of their protected health information may have been viewed or obtained by an unauthorized individual who gained access to the email account of one of its employees. Assisted by a third-party cybersecurity firm, PCI determined the email account was compromised for more than a month, with the unauthorized individual first accessing the account on April 5, 2020. The account was secured on May 8, 2020. A review of the compromised account concluded on August 8, 2020 and revealed it contained a variety of protected health information. In addition to names, affected patients had one or more of the following data elements exposed: date of birth, medical information such as diagnosis and treatment information, financial account information, and/or credit/debit card number. To prevent further breaches, PCI has implemented multi-factor authentication on its email accounts and has provided further training to the workforce on email security. Potential Data Breach Discovered by McLaren Oakland Hospital McLaren...
Sen. Warner Seeks Answers about Suspected Universal Health Services Ransomware Attack
Universal Health Services has confirmed that all 250 of its hospitals in the United States are back up and running after a suspected ransomware attack that knocked out its systems for 3 weeks. The attack started on or around September 27, 2020. All systems were brought back online by October 12. An update was posted on the UHS website this week saying, “With back-loading of data substantially complete at this point, hospitals are resuming normal operations.” While systems were down, clinicians were forced to work with pen and paper in order to continue providing care for patients and, at some locations, patients had to be diverted to alternate facilities to receive treatment. The health system reported the security breach as a malware attack which forced it to shut down its network; however, several insiders took to Reddit to voice their concerns and explain that this was a ransomware attack. Based on the data posted by those insiders, the attack appeared to have involved Ryuk ransomware. The operators of Ryuk ransomware are known to exfiltrate data prior to the...
CISA/FBI: APT Groups Chaining Legacy Vulnerabilities with Netlogon Flaw
A joint advisory has been issued by the Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) warning about sophisticated advanced persistent threat actors chaining exploits for multiple vulnerabilities in cyberattacks against federal and state, local, tribal, and territorial (SLTT) government networks, critical infrastructure, and election support systems. While there have been successful attacks on the latter, no evidence has been found to suggest any election data have been compromised to date. Several legacy vulnerabilities are being targeted along with more recently discovered vulnerabilities, such as the Windows Server Netlogon remote protocol vulnerability – CVE-2020-1472 – also known as Zerologon. A patch for the flaw was issued by Microsoft on August 2020 Patch Tuesday but patching has been slow. Chaining vulnerabilities in a single cyberattack is nothing new. It is a common tactic used by sophisticated threat groups to compromise networks and applications, elevate privileges, and achieve persistent access to victims’...
