2022-07-11 10:00:00 | 5 Common blind spots that make you vulnerable to supply chain attacks (lien direct) | This blog was written by an independent guest blogger. Over the past several years, hackers have gone from targeting only companies to also targeting their supply chain. One area of particular vulnerability is company software supply chains, which are becoming an increasingly common method of gaining access to valuable business information. A study by Gartner predicted that by 2025, 45% of companies will have experienced a supply chain attack. Supply chain attacks can come in various ways, whether by malicious code injected into enterprise software or vulnerabilities in software your company uses. To mitigate this risk, companies must learn about the methods used to execute attacks and understand their company’s blind spots. This article will look at 5 recent software supply chain attacks and how third-party partners can pose a security risk to your company. We’ll make recommendations for how to secure your business against supply chain attacks and how you can engage in early detection to respond to threats before they take down your enterprise. What is a software supply chain attack? The CISA or US Cybersecurity and Infrastructure Security Agency defines a software supply chain attack as an attack that “occurs when a cyber threat actor infiltrates a software vendor’s network and employs malicious code to compromise the software before the vendor sends it to their customers. The compromised software then compromises the customer’s data or system.” A software supply chain includes any company you purchase software from and any open-source software and public repositories from which your developers pull code. It also includes any service organizations that have access to your data. In the aggregate, all of these different suppliers exponentially increase the surface area of a potential attack. Software supply chain attacks are particularly dangerous because the software supply chain acts as an amplifier for hackers. This means that when one vendor is impacted, hackers can potentially reach any of their customers, giving them greater reach than if they attacked a single target corporation. Two primary reasons contribute to the danger, according to CISA: Third-party software products usually require privileged access; They often require frequent communication between the vendor’s own network and the vendor’s software on customer networks. Attackers leverage privileged access and a privileged network access channel as their first point of access. Depending on the level of available access, attackers can easily target many devices and levels of an organization. Some industries, like healthcare, are of particular vulnerability because they possess huge volumes of patient data subject to strict compliance regulations and laws. Five major supply chain attacks In recent memory, software supply chain attacks have gathered increased attention from the public because of how damaging they can be to a company and its reputation. The Log4j vulnerability demonstrated just how vulnerable companies can be to relying on third-party software, for example. Other high-profile attacks like the SolarWinds SUNBURST attack and Kaseya VSA (REvil) attack also provided painful reminders of how damaging supply chain attacks can be. The SolarWinds SUNBURST backdoor On December 13th, 2020, the SUNBURST backdoor was first disclosed.

2020-12-15 12:21:00 | SolarWinds Trojan: Affected enterprises must use hot patches, isolate compromised gear (lien direct) | Hot patching and isolating potentially affected resources are on the IT response schedule as enterprises that employ SolarWinds Orion network-monitoring software look to limit the impact of the serious Trojan unleashed on the platform.The supply-chain attack, reported early this week by Reuters and detailed by security researchers at FireEye and Microsoft involves a potential state-sponsored, sophisticated actor gained access to a wide variety of government, public and private networks via Trojanized updates to SolarWind's Orion network monitoring and management software. This campaign may have begun as early as spring 2020 and is ongoing, according to FireEye and others. | Patching | Solardwinds |
