A new report revealed that nearly one-third of cyber incidents reported in Q3 2018 were classified as “destructive attacks,” putting election security at risk in the lead-up to the 2018 midterms.

In its “Quarterly Incident Response Threat Report” for November 2018, Carbon Black found that 32 percent of election-season cyberattacks were destructive in nature — that is, “attacks that are tailored to specific targets, cause system outages and destroy data in ways designed to paralyze an organization’s operations.” These attacks targeted a wide range of industries, most notably financial services (78 percent) and healthcare (59 percent).

In addition, the report revealed that roughly half of cyberattacks now leverage island hopping, a technique that threatens not noly the target company, but its customers and partners as well. Thirty percent of survey respondents reported seeing victims’ websites converted into watering holes.

Time to Panic About Election Security? Not So Fast

Despite these alarming statistics and the very real risks they signify, Cris Thomas (aka Space Rogue) of IBM X-Force Red told TechRepublic that since voting machines are not connected to the internet, a malicious actor would need physical access to compromise one. This could prove challenging for attackers, who must understand not only the vulnerabilities in each individual voting machine, but also each precinct’s policies.

Bad actors could theoretically stage an attack by obtaining an official voting machine before the election and gaining physical access to it on voting day, but these machines come with checks and balances that detect when votes are changed, decreasing the liklihood of a successful attack.

Attacks Are Growing Increasingly Evasive — and Expensive

Still, the rise in destructive attacks is particularly concerning given that, as reported by Carbon Black, attacks across the board are becoming more difficult to detect. In addition, 51 percent of cases involved counter-incident response techniques, and nearly three-quarters of participants specifically witnessed the destruction of logs during these incidents. Meanwhile, 41 percent observed attackers circumventing network-based protections.

These evasive tactics could prove costly for companies. According to Accenture, threat actors could set companies back as much as $2.4 million with a single malware incident, with cybercrime costing each organization an average of $11.7 million per year.

How to Defend Against Destructive Attacks

Security professionals can defend their organizations against destructive attacks by developing a dedicated framework to predict what steps an adversary might take once inside the network. Security teams should supplement this framework with AI tools that can use pattern recognition and behavior analysis to stay one step ahead of cyberthreats.

Beyond Requirements: Tapping the Business Potential of Data Governance and Security

3 min read - Doom and gloom. Fear, uncertainty and doubt. The "stick" versus the "carrot". What do these concepts have in common? They have often provided the primary motivation for organizations’ data governance and security strategies. For the enterprise, this mindset has perpetuated the idea that data governance, data security and data privacy are reactive cost centers existing due to externally imposed requirements or mandates.Yet, what if data governance and security practices could upend the prevailing paradigm and demonstrate direct business value?[button link="https://community.ibm.com/community/user/security/events/event-description?CalendarEventKey=8d7fdc61-97bf-43b0-b7d6-018756e436a6&CommunityKey=aa1a6549-4b51-421a-9c67-6dd41e65ef85&Home=%2fcommunity%2fuser%2fsecurity%2fcommunities%2fcommunity-home%2frecent-community-events"…

Protecting Against Remote Monitoring and Management Phishing

3 min read - You use remote monitoring and management (RMM) software to closely monitor your cyber environment and keep your organization safe. But now cyber criminals are specifically targeting these tools, causing legitimate software to become a vulnerability. This is the latest type of attack in an increase in a recent trend of disruptive software supply chain attacks. The Cybersecurity and Infrastructure Security Agency (CISA) recently released an alert about the malicious use of legitimate remote monitoring and management (RMM) software. Last fall,…

Secure-by-Design: Which Comes First, Code or Security?

4 min read - For years, developers and IT security teams have been at loggerheads. While developers feel security slows progress, security teams assert that developers sacrifice security priorities in their quest to accelerate production. This disconnect results in flawed software that is vulnerable to attack. While advocates for speed and security clash, consumers must often pay the price when threat actors strike. 48% of developers admitted they were still shipping code with vulnerabilities in 2022. It’s clearly time for a change. Many believe…

ITG10 Likely Targeting South Korean Entities of Interest to the Democratic People’s Republic of Korea (DPRK)

7 min read - In late April 2023, IBM Security X-Force uncovered documents that are most likely part of a phishing campaign mimicking credible senders, orchestrated by a group X-Force refers to as ITG10, and aimed at delivering RokRAT malware, similar to what has been observed by others. ITG10's tactics, techniques and procedures (TTPs) overlap with APT37 and ScarCruft. The initial delivery method is conducted via a LNK file, which drops two Windows shortcut files containing obfuscated PowerShell scripts in charge of downloading a…
