FBI Investigating Data Breach Affecting U.S. House of Representatives Members and Staff

The Federal Bureau of Investigation (FBI) is investigating a data breach affecting members and staff of the U.S. House of Representatives. The breach saw account and sensitive personal information belonging to them and their families stolen from the servers of DC Health Link, which administers their health care plans.

While US House Chief Administrative Officer Catherine L. Szpindor has said, “it was unclear how many people had been affected by the breach.” A sample of the data reportedly posted on a hacking forum showed details of around 170,000 people. The information included names, dates of birth, addresses, email addresses, phone numbers, and Social Security numbers. At least one threat actor has reportedly put the data up for sale.

nGuard’s MECC (Managed Event Collection and Correlation) can help protect against malicious attacks by collecting and analyzing log data from various sources. MECC can then alert security teams to potential threats and provide them with the information they need to investigate and respond to an ongoing or potential attack. Should your organization fall victim to an attack like this, call nGuard to help with our Cyber Security Incident Response services.

New FortiOS and FortiProxy Critical Vulnerabilities

Fortinet has released patches to address 15 security flaws, including one critical vulnerability in FortiOS and FortiProxy that could allow an attacker to take control of affected systems. The buffer underwrite flaw (CVE-2023-25610) is rated 9.3 out of 10 for severity and was discovered by Fortinet’s internal security teams. The vulnerability could enable a remote, unauthenticated attacker to execute arbitrary code on the device or cause a denial-of-service attack. Fortinet has not yet seen any malicious exploitation attempts against the flaw, but users are urged to apply the patches quickly, as prior flaws in software have been actively abused in the wild. Workarounds include disabling the HTTP/HTTPS administrative interface or limiting IP addresses that can reach it. Just last week, nGuard wrote about another Fortinet critical vulnerability that was actively being exploited. As this continues to develop, nGuard has a number of solutions that can help your organization stay ahead of the curve, including internal penetration testing and vulnerability management.

Over 40% of Industrial Control Systems (ICS) Were Attacked in 2022

Over 40% of industrial control systems (ICS) computers globally experienced malicious attacks in 2022, according to Kaspersky research into telemetry statistics. The report highlighted growth in Russia, which saw a 9% increase in malicious activity in 2022, but Ethiopia was the top target overall with 59% of its ICS footprint seeing malicious activity.

Kaspersky noted that blocked malicious scripts and phishing pages targeting ICS were particularly common threats, seeing an 11% rise from 2021. The percentage of ICS computers experiencing malicious activity varied from 40.1% in Africa and Central Asia to 14.2% and 14.3% respectively in Western and Northern Europe. nGuard has been helping protect Industrial control systems, SCADA networks, and critical infrastructure for over 20 years with security assessments, penetration testing, incident response, and managed SIEM services.

Low-coverage Cyber Insurance Plans Help Meet Compliance and Contractual Requirements

As the cyber insurance market experiences a surge in claims for ransomware attacks, insurance carriers and brokers have started imposing tighter rules on the companies that can qualify for coverage, raising prices and reducing the amount of coverage offered per policy. nGuard recently wrote about requirements needed to obtain cyber insurance. Policy coverages have significantly dropped in recent times, with some as low as $5m, and some companies cannot purchase as much insurance as they would like. However, some contracts and compliance regulations require that a company have a cyber insurance policy, which can pose a problem for those that lose coverage. Basic policies are now available for more organizations to obtain affordable coverage, allowing them to avoid a breach of compliance and fulfill contractual obligations.

Vulnerability Exploits Overtake Phishing as Initial Attack Vector

Most security professionals will advise the number one way attackers gain an initial foothold on a network is, and continues to be, phishing and social engineering attacks. Palo Alto recently released their 2022 Incident Response Report which confirmed what most would say is true. At a combined 42%, phishing and social engineering make up almost half of all means of initial access.

The second most common way according to the above chart from Palo Alto is software vulnerabilities. However, in the first week of September, Kaspersky released its 2021 Incident Response Overview and it told a different story. 53.6% of the initial attack vectors they responded to were exploits of public-facing applications.

2021 had no shortage of time sensitive critical vulnerabilities including Log4j, Microsoft Exchange ProxyLogon, and three other CVEs related to the ProxyLogon vulnerabilities that were released in March of 2021. When these vulnerabilities are made publicly available it is only a matter of minutes before publicly facing systems are being scanned for vulnerable targets. Within hours, proof of concept exploits become available leading to an extremely high rate of organizations falling for such attacks.

In recent years, organizations have prioritized security awareness training and conducted social engineering and phishing training. But have those same organizations made it a priority to have a vulnerability management program in place?

How can organizations stay ahead of these attack trends? Start by building out a mature security program that includes annual penetration testing, ongoing vulnerability scanning, and a properly configured SIEM to alert on network anomalies. If you suspect a breach, identify a firm capable of responding to security incidents and secure an incident response retainer. Lastly, have an expert conduct a strategic security assessment to compare your organization’s security program to a known security standard like the Center for Internet Security Critical Security Controls.
