A pair of eBay vulnerabilities could have left users of the popular online auction site open to malware and drive-by download attacks, according to the security researcher who discovered and reported them.

In an email sent to Threatpost, Aditya Sood said one of the eBay vulnerabilities involved a failure to ensure malware wasn’t camouflaged within the image extensions of a file, but that in itself wasn’t the biggest issue. More importantly, cybercriminals could also potentially use URLs generated by uploading malware in drive-by attacks due to the fact that eBay was returning messages with an identical file path.

As The Register pointed out, this is hardly the first time security concerns have been raised about the online auction and e-commerce service. Earlier research uncovered a way to use specially designed links to potentially take over any eBay account. The company has apparently learned some lessons from that incident. While BBC News said that cross-site scripting vulnerability apparently persisted for much of 2014 before it was finally addressed, a spokesperson told EcommerceBytes the current eBay vulnerabilities have already been fixed.

Beyond problems with its public-facing sites, eBay was also mentioned in coverage of a PandaLabs security report on ITProPortal that showed how much worse security issues have become over the past year. The story recalled an incident last year in which stolen employee credentials led to a massive data breach of customer passwords; some might argue those types of insider threats are the most dangerous of all.

In the meantime, it’s interesting that eBay vulnerabilities are being discovered just as the company is planning to formally separate from PayPal. Although the online payment platform has had its own security issues in the past, including a financial phishing scheme, PayPal recently said it was going to beef up its own data protection capabilities by acquiring CyActive, a startup whose products are designed to predict how malware will evolve. According to Reuters, PayPal has already set up a security operations center near CyActive’s home base in Israel.

Although it doesn’t look like anyone was affected by the recent eBay vulnerabilities, it’s a good reminder for similar online companies to be vigilant, as a story on Effect Hacking suggested. If cybercriminals had exploited these flaws, all it would take is looking at an image with embedded malware to launch a cyberattack. That won’t just stop customers from shopping — it will likely stop them from ever returning to the site again.

Hive0051 goes all in with a triple threat

13 min read - As of April 2024, IBM X-Force is tracking new waves of Russian state-sponsored Hive0051 (aka UAC-0010, Gamaredon) activity featuring new iterations of Gamma malware first observed in November 2023. These discoveries follow late October 2023 findings, detailing Hive0051's use of a novel multi-channel method of rapidly rotating C2 infrastructure (DNS Fluxing) to deliver new Gamma malware variants, facilitating more than a thousand infections in a single day. An examination of a sample of the lures associated with the ongoing activity reveals…
