To mark Cyber Security Awareness Month, DXC focuses on the five primary types of cyber attackers: nation-state, cybercriminals, hacktivists, lone-wolf hackers and insider threats. Nation-state attackers: These state-backed cyber criminals typically are focused on trying to project power in a region or gain an economic or political advantage over a rival. Their activities range from traditional espionage to disrupting adversaries by leaking confidential data. Nation-states are often associated with advanced persistent threats (APTs), in which an attacker gains access to a system and remains undetected for an extended period. These groups typically use the most sophisticated techniques. One of the most infamous nation- state hacking groups is Russian-backed APT28, also known as Strontium or Fancy Bear, which was recently observed exploiting internet of things (IoT) devices, including a VOIP 8,000 phone, an office printer and a video decoder. Microsoft enterprise customers targeted or compromised by nation- Nation-state activity is increasing around the globe. New reports accuse the Chinese state attacks in 2019 government of intrusions into telecommunications networks to track Asian dissidents, and Iran is likely to ramp up its cyber espionage efforts against Saudi Arabia and the United States. Government agencies, defense contractors and critical infrastructure are key potential targets. Cyber criminal groups: Cyber criminal groups, motivated by financial gain, have shifted from targeting end users to more sophisticated big game hunting, with large corporations and government agencies as their targets. The public sector has become a major target. Over the past 6 months, cyber criminal campaigns used ransomware to lock down city government services in five U.S. states, plus 23 Texas towns, and 500 schools and colleges. Notorious payment-card skimming family Magecart is also acting opportunistically. Employing a new tactic, Magecart bots recently infected 17,000 websites by exploiting 78 days improperly configured Amazon Cloud S3 buckets to steal card information. Global median time to detect a These types of threats underscore the need for rigorous cyber defenses as well as a plan breach in 2019 for how to respond and recover — or whether to pay or not pay the ransom. Hacktivists: Hacktivists are politically motivated, ideology-driven actors. One well-known hacktivist group, Anonymous, first made headlines when it retaliated against the Church of Scientology’s perceived internet censorship using distributed denial-of-service (DDOS), spamming and other attacks. Increasingly, social media is the target, as evidenced by the account takeover of Twitter cofounder Jack Dorsey — crusader against online hate groups — which was used to send out pro-Nazi tweets. Even law enforcement is not immune, with London’s Metropolitan Police Twitter account sending out a series of bizarre and profane messages in July. 3 October 2019 Hacktivists typically have lower levels of technical sophistication, and social media accounts offer a soft target that allows them to project their disruptive efforts to a wide audience. Organizations should carefully consider security basics around corporate social media platforms, including monitoring, auditing and requirements for complex passwords and multifactor authentication. Lone-wolf hackers: Not part of an organized crime group, lone-wolf hackers are often opportunists motivated by financial gain. In some cases, lone-wolf hackers can grow their ranks quickly. In addition to the two lone wolves arrested for the TalkTalk hack of nearly 160,000 customer accounts, authorities suspected that at least 10 more individuals were involved in the scheme to extort the company’s CEO. Lone-wolf hackers are more likely to target smaller organizations, public agencies and NGOs. Their aim is usually to gain access to data that can be sold on the dark web or 184% sensitive or embarrassing data that can be used for extortion. Increase in average ransom pay- ment in Q2 2019 Insider threats Unlike organized cyber crime groups, malicious insiders often operate on a small scale, looking for opportunities for personal gain, or for retribution against a real or perceived slight by their employer. The prospect of monetary gain drives many insider threats with opportunities to embezzle or sell stolen proprietary information. For example, a disgruntled IT engineer at Scale AI hacked the company network and made hundreds of small fraudulent payments into PayPal accounts before getting caught. In 2018, Tesla CEO Elon Musk announced that an insider exported large amounts of highly sensitive Tesla data to unknown third parties. Another potential motivator for insiders is whistleblowing. Disenfranchised workers can do Group 4 significant reputation damage by publicly exposing what they consider to be unethical practices, even if the accusations later prove to be unfounded. Groups 1 and 2 Insider threats are among the most complex to detect and prevent. A maliciously motivated insider often has intimate knowledge of the company’s internal network and Group 5 security configurations, as well as the requisite skills to operate bespoke tooling. Preventing such attacks requires a layered approach and mature security architecture. AI-powered endpoint protection and user-behavior analytics within the SIEM can help Group 6 identify malicious actions, such as the clearing of audit logs, suspicious access of materials or access of systems at unusual times. Further, privileged users should be audited more frequently and thoroughly. Group 11 Emotet returns after 4-month break Emotet spam campaigns have returned after a four-month period of inactivity with a new malspam campaign.. Group 12 On September 16, Malwarebytes and Spamhaus spotted a series of new spam emails written in Italian, Polish and German that contained a document-themed lure in the form of either a malicious attachment or links to malicious documents online. This was followed approximately 24 hours later by English-language phishing messages with a subject line containing the phrase “Payment Remittance Advice.” 4 October 2019 Known Emotet Spreader Modules This latest wave of phishing messages targeted domains across a range of countries NetPass including Argentina, Germany, the United States and the United Kingdom. Recovers all network passwords stored on a system for the logged-on user. Impact Outlook Scraper Possibly the biggest threat posed by Emotet is that it can be used as a delivery vector for Scrapes names, dates, email addresses more dangerous payloads. Emotet Trojans have been partnered with TrickBot and Ryuk and email bodies from Outlook accounts. Information found in the email account is ransomware strains to create a combination that

  • Bluekeep Vulnerability
    Monthly Cybersecurity Newsletter June 2019 Issue Enterprise Security and Risk Management Office (ESRMO) From the Desk of the State Chief Risk Officer – Maria Thompson BlueKeep Vulnerability The National Security Agency (NSA) has released a cybersecurity advisory for a vulnerability (CVE-2019-0708) called “BlueKeep” that affects several old versions of the Microsoft Windows operating system. The BlueKeep vulnerability allows for an unauthenticated attacker to connect to a vulnerable system using the Remote Desktop Protocol (RDP) – formerly known as Terminal Services – and send specially crafted requests without user interaction. An attacker who successfully exploits this vulnerability could then install programs; view, change, or delete data; or create new accounts with full user rights on the vulnerable machine. Microsoft warns that the vulnerability is also “wormable,” meaning it can potentially spread from system to system without user interaction. The “BlueKeep” vulnerability is present in Windows 7, Windows XP, and Server 2003 and 2008. Windows 8 and Windows 10 are not currently vulnerable. Although Microsoft has issued a patch for this vulnerability, potentially millions of machines are still vulnerable. Microsoft strongly recommends installing the updates for this vulnerability as soon as possible, after appropriate testing. The update addresses the vulnerability by correcting how Remote Desktop Services (RDS) handles connection requests. In addition to installing the patch, the following steps may also help reduce the risk of this vulnerability. • Disable RDS if it is not required. Disabling unused and unneeded services reduces exposure to security vulnerabilities. • Enable Network Level Authentication (NLA) on systems running supported Windows editions. With NLA turned on, an attacker would first need to authenticate to RDS with a valid account on the target system before exploiting the vulnerability.
