This post dives into the details of the HTTP/2 protocol, the feature that attackers exploited to generate the massive Rapid Reset attacks, and the mitigation strategies we took to ensure all our customers are protected

Akamai researchers have discovered a novel obfuscation technique that Magecart attackers are using to hide malicious code and infiltrate websites.

There is no shortage of researchers and industry titans willing to warn us about the potential destructive power of artificial intelligence. Reading the headlines, one would hope that the rapid gains in AI technology have also brought forth a unifying realization of the risks—and the steps we need to take to mitigate them.

Le nombre d’aînés ciblés par des cyber-escrocs en Suisse est élevé.

C'est le black-out informatique au centre hospitalier de l'Ouest vosgien. Les établissements de Vittel et Neufchâteau ont été victimes d'une cyberattaque dans la nuit de vendredi à samedi. Les urgences restent maintenues, mais les activités programmées sont suspendues jusqu'à lundi inclus.

At least a million data points from 23andMe accounts appear to have been exposed on BreachForums. While the scale of the campaign is unknown, 23andMe says it's working to verify the data.

A few days ago, ZDI went public with no less than six 0days in the popular mail server Exim. Ranging from ‘potentially world-ending' through to ‘a bit of a damp squib’, these bugs were apparently discovered way back in June 2022 (!) - but naturally got caught up in the void between the ZDI and Exim for quite some time. Mysterious void.

The Red Cross writes rules of engagement for civilian hackers as numbers rise

• Cybersecurity Firm Human Security has discovered malware on dozens of streaming devices and iOS/Android apps.
• A huge number of Android TV boxes contain malware capable of conducting ad fraud, creating fake accounts, and selling access to home networks.
• Researchers found that the malware they have dubbed Badbox is not only tricky to detect but difficult to remove as well.
• Android TV box users must prefer installing apps from reliable sources and keep their devices up-to-date.
• Human Security has already shared details of its findings with concerned law enforcement agencies.

In September of 2023, X-Force uncovered a campaign where attackers were exploiting the vulnerability identified in CVE-2023-3519 to attack unpatched NetScaler Gateways to insert a malicious script into the HTML content of the authentication web page to capture user credentials. The campaign is another example of increased interest from cyber criminals in credentials. The 2023 X-Force cloud threat report found that 67% of cloud-related incident response engagements were associated with the use of stolen credentials.

Tech companies continue to insist that AI-generated content is the future as they release more trendy chatbots and image-generating tools. But despite reassurances that these systems will have robust safeguards against misuse, the screenshots speak for themselves.

In 2020, we launched a novel format for our vulnerability reward program (VRP) with the kCTF VRP and its continuation kernelCTF. For the first time, security researchers could get bounties for n-day exploits even if they didn’t find the vulnerability themselves. This format proved valuable in improving our understanding of the most widely exploited parts of the linux kernel. Its success motivated us to expand it to new areas and we're now excited to announce that we're extending it to two new targets: v8CTF and kvmCTF.

23andMe has confirmed to BleepingComputer that it is aware of user data from its platform circulating on hacker forums and attributes the leak to a credential-stuffing attack.

Several new Mirai variant families were widely deployed in September 2023, among which hailBot, kiraiBot and catDDoS are the most active.

Supermicro has released BMC IPMI firmware updates to address multiple vulnerabilities impacting select motherboard models.

Behind the screens: An overview of hidden attack surfaces in powerful BMC chip infrastructure.

Since early April 2023, an attacker has been relentlessly deploying hundreds of malicious packages through various usernames, accumulating nearly 75,000 downloads. Our team at Checkmarx’s Supply Chain Security has been on this malicious actor’s trail since early April, documenting each step of its evolution. We have been actively observing an attacker who seems to be evermore refining their craft. 

Double extortion ransomware attacks have reached very high numerical values. One of the key elements, when suffering such an attack, concerns the negotiation that can be initiated (not always!) with the ransomware gang. The analysis, carried out by the SEC4U team, of hundreds of negotiations makes it possible to apply a scientific approach to this

On 10/4/2023, Atlassian published a security advisory on CVE-2023-22515, a privilege escalation vulnerability affecting Confluence Server & Data Center.
