Many of the city of Baltimore’s public services remain offline two weeks after the municipality fell victim to a ransomware attack.

On May 21, NPR noted that the ransomware attack, which is believed to have occurred on May 7, continues to affect several of Baltimore’s public services. City employees still can’t use their government-issued computers or email accounts to get work done. Instead, employees have been using their personal laptops and email accounts or even reverting back to paper-based processes to conduct official government business.

According to Ars Technica, the infection disrupted the city’s ability to receive payments for water bills, parking tickets and citations for traffic violations as well. It also affected the Baltimore Police Department’s network of surveillance cameras, but had no effect on the city’s emergency systems.

City officials said they don’t intend to pay the ransom of 13 bitcoins — currently worth more than $100,000 — despite the fact that the offending malware sample, a variant of RobbinHood, currently has no publicly available decryptors. Officials also indicated that they will continue to work with the FBI and Secret Service, who are both investigating the incident.

Not the First Cyberattack on a Municipality

This isn’t the first time that a municipality has fallen victim to a ransomware attack. Back in March 2018, for instance, the city of Atlanta suffered an infection that disrupted employees’ access to the government network and affected public payment systems. As the Atlanta Journal-Constitution reported, the attack could cost Atlanta taxpayers as much as $17 million.

Around that same time, Baltimore suffered its own infection that shut down the city’s 911 emergency dispatch system, noted the Baltimore Sun. This attack came a little more than a year before WITN broke the news of a RobbinHood infection affecting the city government in Greenville, North Carolina.

How to Defend Against a Ransomware Attack

Organizations are increasingly reporting ransomware attacks and refusing to pay ransoms. Security professionals can join this ongoing fight by putting prevention first and developing a layered defensive strategy that makes use of anti-malware tools, anti-spam filters and security awareness training. Proper instruction should teach all employees — from entry-level to C-suite — about some of the most common social engineering techniques employed by digital attackers today.

Cyberattacks are on the rise as adversaries find new ways of creating chaos and increasing profits. Attacks evolve constantly and often involve real-world consequences. The growing criminal Software-as-a-Service enterprise puts ready-made tools in the hands of threat actors who can use them against the software supply chain and other critical systems.

RansomExx Upgrades to Rust

IBM Security X-Force Threat Researchers have discovered a new variant of the RansomExx ransomware that has been rewritten in the Rust programming language, joining a growing trend of ransomware developers switching to the language. Malware written in Rust often benefits from lower AV detection rates (compared to those written in more common languages) and this may have been the primary reason to use the language. For example, the sample analyzed in this report was not detected as malicious in the…

Why Operational Technology Security Cannot Be Avoided

Operational technology (OT) includes any hardware and software that directly monitors and controls industrial equipment and all its assets, processes and events to detect or initiate a change. Yet despite occupying a critical role in a large number of essential industries, OT security is also uniquely vulnerable to attack. From power grids to nuclear plants, attacks on OT systems have caused devastating work interruptions and physical damage in industries across the globe. In fact, cyberattacks with OT targets have substantially…

Resilient Companies Have a Disaster Recovery Plan

Historically, disaster recovery (DR) planning focused on protection against unlikely events such as fires, floods and natural disasters. Some companies mistakenly view DR as an insurance policy for which the likelihood of a claim is low. With the current financial and economic pressures, cutting or underfunding DR planning is a tempting prospect for many organizations. That impulse could be costly. Unfortunately, many companies have adopted newer technology delivery models without DR in mind, such as Cloud Infrastructure-as-a-Service (IaaS), Software-as-a-Service (SaaS)…
