In addition to immediate financial losses and strategic threat awareness. from business disruption, victims face longer-term reputational damage, such as the This report is a part of recent takeover of the London police Twitter account by hacktivists. DXC Labs | Security, which provides insights and thought leadership to This month it’s clear that the threat landscape is continuing to evolve. For example, the security industry. we’re seeing new twists on familiar threats, such as phishing campaigns that use Quick Response (QR) codes to target mobile devices, and the latest Magecart exploit of using Intelligence cutoff date: poorly configured cloud buckets to inject the group’s notorious card-skimming code. 24 July 2019 Table of Contents Threat Ransom payments nearly double in second Multi-industry updates quarter QR codes used to evade mailbox protections Multi-industry Magecart card skimmer hits thousands of Amazon Web Services S3 buckets Multi-industry Suspected malware developer arrested by Dutch National Police Unit Multi-industry Nation state DNS infrastructure hijacking campaigns Public Sector, & geopolitical continue Energy updates Linux desktop malware has suspected Russian links Vulnerability Substantial vulnerabilities in Zoom Multi-industry updates videoconferencing application Critical vulnerability discovered in ProFTPD Multi-industry Incidents/ Huge fines and settlements follow British Travel and Breaches Airways and Equifax breaches Transportation, Financial Services London police suffer social media hijacking Public Sector 2 August 2019 Threat updates Ransom demands nearly double in second quarter The average payment demand related to a ransomware infection has almost doubled, largely as a result of several organizations, including two Florida cities, falling victim to Ryuk ransomware the Ryuk and Sodinokibi ransomware strains. Who? Impact Sole operation by Eastern European cybercriminal group Grim Spider Data from ransomware incident response company Coveware shows that in the second quarter of 2019 the average ransom payment increased by 184 percent to $36,295. The What? analysis also showed that, although public and private sector entities were targeted, public sector victims paid an average of 10 times more in ransom. This dynamic is possibly “Big game hunting” ransomware campaigns, which focus on the largest enterprise fueled by increased media scrutiny of public sector entities and their requirement for environments system availability. How? Increasing ransom demands are likely due to threat actors focusing deployment of Ryuk A combination of automated infection with and Sodinokibi in large enterprise environments. This trend is seen in other prominent manual privilege escalation and expansion strands of ransomware, including LockerGoga, MegaCortex and GandCrab. of access typically using TrickBot or Emotet trojans via malspam for initial access Deployment methods for these strains vary. Ryuk’s operators use common banking Trojans to gain initial access to corporate environments before expanding network access Notable example? and deploying the ransomware binary, normally exploiting Active Directory. Sodinokibi Gained more than $1 million in ransom from has focused on compromising managed services providers (MSPs) and deploying Riviera Beach and Lake City in Florida during attacks in May ransomware to managed endpoints to maximize the scale of the infection. DXC perspective The widely reported decline in ransomware since 2017 is deceptive. The ransomware threat is evolving. There may be fewer total events, but those that occur are often more serious. For example, Ryuk ransomware garnered more than $1 million in ransom from Riviera Beach and Lake City in Florida during attacks in May. Increased sophistication in deployment tactics and a renewed focus on “big game hunting” means the threat has never been greater to enterprise environments. Attacks now seek to infect entire organizations in a single incident rather than a handful of hosts or individual network segments. Denial of initial access is key to prevention. Effective identity and access management controls, network access controls, phishing mail protections and training, and next- generation endpoint solutions can all help prevent account compromise and the delivery of malware. Source: Bleeping Computer QR codes used to evade mailbox protections Among the June 2019 Windows updates, Microsoft released patches for CVE-2019-1040, a vulnerability in the NT LAN Manager (NTLM) message integrity code (MIC) protection mechanism. Impact A phishing campaign was detected using QR codes to avoid detection by URL analysis. Individuals received spam emails posing as a SharePoint notification with an embedded QR code to scan and view an associated document. 3 August 2019 Impact Using a QR code successfully bypasses most traditional mailbox protections and avoids URL sandboxing. The phishing site is optimized for mobile browsers, highlighting the focus on mobile devices. This targeting enables adversaries to bypass the corporate security Most-attacked industries in July zone while retaining a high likelihood of obtaining user credentials. Stolen credentials • Financial services will subsequently be used to achieve initial access to corporate networks by the phishing • Professional services/consulting actor or may be sold to third-party criminal groups for use in further campaigns. • Telecommunications • Manufacturing DXC perspective • Insurance The prevalence of bring-your-own-device (BYOD) policies provides adversaries with an expanded attack surface. Credential phishing remains a prominent attack vector for a range of sophisticated criminal- and state-sponsored actors. We are likely to witness continued efforts to achieve credential compromise outside of the traditional corporate security zone. Targeting of mobile devices is on the increase beyond credential phishing, with several campaigns deploying new mobile-specific malware. The innovative use of QR codes to bypass protections demonstrates the importance of layered security and visibility into access of cloud applications.
