Giant car rental company Avis disclosed that an August 2024 data breach affected 299,006 of its customers.

According to the letter it sent out to those who have been affected, on August 3, 2024, a threat actor gained unauthorized access to its business applications. The data was access until August 6. The data breach was detected on August 14. The company took steps to end the access and launched an investigation with third-party experts, as well as alerted the authorities and notified the Maine Attorney General’s Office.

The stolen data includes personal information such as names, mailing addresses, email addresses, phone numbers, dates of birth, credit card numbers with expiration dates and driver’s license numbers – critical information that can be used for identity theft or fraud.

The car rental did not disclose technical details about the attack

To mitigate possible damage, Avis is providing all affected customers with one year of free credit monitoring through Equifax.

Giant oil service company Halliburton confirmed that it was hit by a cyberattack that forced the company to take systems offline.

In a SEC filing, Halliburton said that “On August 21, 2024, Halliburton Company (the “Company”) became aware that an unauthorized third party gained access to certain of its systems.” The filing further says: “When the Company learned of the issue, the Company activated its cybersecurity response plan and launched an investigation internally with the support of external advisors to assess and remediate the unauthorized activity. The Company’s response efforts included proactively taking certain systems offline to help protect them and notifying law enforcement. The Company’s ongoing investigation and response include restoration of its systems and assessment of materiality.”

Jerico Pictures Inc., doing business as National Public Data (“NPD”), exposed in April 2024 the personal information of nearly 2.9 billion individuals as a result of a data breach.

NPD is background check company that allows its customers to search billions of records with instant results.

In early April, 2024, a threat actor that uses the moniker of USDoD gained access to NPD’s network, and was able to exfiltrate unencrypted PII, including full names, Social Secutiy numbers, address history, and family information, of billions of individuals whose data is stored on NPD’s network.

On April 8, 2024, USDoD announced the sale of a “National Public Data” database on a dark web forum called Breached. It offered the 2.9 billion records for $3.5 million.

Researchers from VX-underground requested and received an advance copy of the data, reviewed the massive file – 277.1GB uncompressed, and confirmed that the data present in it is real and accurate. They also noticed that the database doesn’t contain information from individuals who use data opt-out services. People who did not use data opt-out services and resided in the United States were immediately found. The archive also contains data on deceased people.

A proposed class action lawsuit was filed in U.S. District Court, Southern District of Florida, Fort Lauderdale Division, on behalf of Christopher Hofmann, who said he received a notification from his identity theft protection service provider the month before that his data was on the dark web due to a data breach.

CrowdStrike is being sued by its shareholders after a faulty update released on July 19, 2024 by CrowdStrike Falcon caused Windows systems to display the Blue Screen of Death (BSoD) screen. The flawed release caused widespread global disruptions, impacting critical infrastructure such as airports, hospitals, banks, and government services. It caused 8.5 million Microsoft Windows systems globally to crash.

The lawsuit accuses CrowdStrike executives of making “false and misleading” statements that the company’s software updates were adequately tested.

CrowdStrike denies the allegations and has announced it will oppose the proposed class action lawsuit.

“We believe this case lacks merit and we will vigorously defend the company,” a spokesperson said.

Delta Air Lines’ CEO, Ed Bastian, revealed in a recent CNBC interview that the outage caused by Crowdstrike led to $500 million in losses for the airline. Delta is now seeking compensation from CrowdStrike, as well as from Microsoft.

Both CrowdStrike and Microsoft denied any wrongdoing. CrowdStrike pointed out that “no other US airline had cancelled one-tenth as many flights”. Microsoft pointed out that Delta’s IT systems were outdated.

The company’s share price dropped 32% in the 12 days after the incident, causing a loss in market value of $25 billion.

A defective update released by CrowdStrike Falcon is causing Windows systems to display the Blue Screen of Death (BSoD) screen. The incident is causing widespread global disruptions, impacting critical infrastructure such as banks, airports and hospitals.

The company stated that they have identified the content deployment related to this issue and reverted those changes.

The bad release, containing an invalid Windows driver, was published just after midnight Eastern time on July 19, 2024, and rolled back an hour and a half later, at 1:27 AM Eastern, CrowdStrike said. But by then millions of computers had already automatically downloaded the faulty update. When Windows devices using CrowdStrike’s cybersecurity tools tried to access the flawed file, it caused an “out-of-bounds memory read” that “could not be gracefully handled, resulting in a Windows operating system crash,” CrowdStrike said. The issue affected only Windows devices, not Mac or Linux machines, and only those that were switched on and able to receive updates during those early morning hours.

IT giants Google and Microsoft were also impacted by the incident: Virtual machines using the CrowdStrike agent experienced serious problems.

What’s been described as the largest IT outage in history will cost Fortune 500 companies alone more than $5 billion in direct losses, according to one insurer’s analysis.

CrowdStrike Falcon detects and blocks hacking threats. The company confirmed that the incident was not a result of a cyber attack.

French cloud computing provider OVHcloud revealed in the beginning of July 2024 that it had mitigated in April 2024 the largest ever distributed denial-of-service (DDoS) attack in terms of packet rate, amid an overall increase in DDoS attack intensity. This is just above the previous record of 809 million Mpps reported by Akamai as targeting a large European bank in June 2020.

The analysis of the malicious traffic revealed that most of the source IPs are known as Internet-facing MikroTik routers, specifically cloud core routers CCR1036-8G-2S+ and CCR1072-1G-8S+.

99% of the malicious traffic were TCP ACK flood, originating from around 5,000 source IPs. The remaining 1% was a DNS reflection attack that involved about 15,000 DNS servers, to amplify the traffic, which is not really efficient when trying to achieve high packet rate attacks.

The experts at OVHcloud speculate that the use of MikroTik devices in coordinated DDoS attacks might be due to the “Bandwidth test” feature in RouterOS, which allows administrators to test router throughput by crafting packets and performing stress tests. For versions after 6.44beta39, this feature uses all available bandwidth by default, potentially impacting network usability. Most of the offending IPs identified were running RouterOS v6.44 or above.

British auction house Christie’s has been hit with a class action lawsuit over a May 2024 data breach that compromised the personal information of approximately 500,000 current and former customers. According to the lawsuit, an email Christie’s sent to victims on May 30, 2024 reported that the compromised data included full names, genders, dates of birth, passport numbers and expiration dates, countries of birth, ID numbers and Machine Readable Zone along the bottom of a passport’s identity page.

The lawsuit further claims that Christie’s customers are now threatened by multiple forms of identity theft. These range from the obvious, such as the prospect of bad actors opening fraudulent financial accounts and taking out loans in the names of the exposed clients, to the less intuitive, including using the exposed parties’ data to illegally secure government benefits, obtain driver’s licenses pairing Christie’s clients’ names with alternate photographs and “giving false information to police during an arrest”.
