A cyberattack that swept across Europe on Tuesday knocked out IT systems at global businesses, central banks and state-owned firms. Here are some of the attack victims:

WPP plc (WPPGY)  -- Most of WPP's public websites were rendered inaccessible after the world's biggest advertising group said its IT systems were the focus of a suspected cyberattack. Shares traded down almost 1% in early afternoon.

AP Moeller-Maersk AS (AMKBY)  -- The world's biggest container shipping firm's IT department was also hit, leading to system shutdowns across the Danish company.

TNT Express -- The dutch-based and FedEx (FDX) owned shipping company had systematic interference as an attack target. 

Mondelez (MDLZ) -- The food group said its employees were experiencing technical problems in several regions, but haven't yet confirmed whether it was part of today's widespread cyberattack. Shares traded down over 1% in early afternoon.

Merck & Co (MRK)  -- The healthcare company confirmed its computer network was compromised in the global attack. It pared earlier gains and traded slightly up in early afternoon.

Rosneft -- Russia's biggest oil company said crude production wasn't affected even though it was hit by the attack because the company switched to a reserve control system, it wrote on Twitter (TWTR) .

Evraz -- The Russian steelmaker's IT department was hit, but there was no impact on production sites or employee safety, a spokeswoman told Reuters.

Ukrenergo -- Ukraine's state power distributor's IT system was compromised, but it didn't affect the power supply or operations.

National Bank of Ukraine -- The central bank said an unknown virus restricted everyday functionality for customers. It urged customers to allow specialists to do their job, but advised them not to open e-mails from unknown senders.

Antonov -- The Ukrainian state-backed aircraft manufacturer was also hit. A spokeswoman said it is unclear how serious the attack is, according to Reuters.

Oschadbank -- One of Ukraine's largest state-owned lenders said a "hacking attack" affected services, but no customer data was compromised.

What's Hot On TheStreet

Another bank is bullish on Alibaba: JP Morgan initiated Chinese e-commerce giant Alibaba (BABA) with an overweight rating and $190 price target in a new note Tuesday, representing more than 30% growth over Monday's closing price of $142.73. In JP Morgan's eyes, Alibaba is entering a transformation from a pure play e-commerce company to a data-driven beast that stands to power its bottom line more than most expect.

"We believe Alibaba's core commerce is expanding from traffic monetization to data monetization and such trend will quickly expand to its media/cloud businesses," writes JP Morgan analyst Alex Yao. "Such expansion not only allows Alibaba to tap into non-transaction-based corporate budget (e.g. market research, brand awareness, and customer service), but also supports our investment thesis based on sustainable revenue/earnings growth."

A key Walmart business springs back to life: Walmart (WMT) is starting to see long-awaited sales growth at its U.K. Asda division as Britons shift their shopping habits towards food purchases with a slump in consumer confidence and surging inflation, TheStreet's Lisa Botter reports. Sales at Asda rose by 2.2% for the 12-weeks ended June 18, well ahead of the 0.9% pace notched in the 12 weeks to May 21, according to new data from research firm Kantar.

Different strategies emerge in driver-less cars: Alphabet Inc.'s (GOOGL) deal with rental car giant Avis Budget Group Inc. (CAR) to have Avis manage some self-driving test cars developed by Alphabet's Waymo unit and Fiat Chrysler (FCAU) feels a little overblown, writes TheStreet's Eric Jhonsa. The deal only covers test cars deployed in one metro area (Phoenix, Ariz.), and isn't exclusive, Jhonsa points out.

Meanwhile, Apple Inc.'s (AAPL) deal with Avis rival Hertz Global Holdings Inc. (HTZ) feels even smaller. Apple, which has reportedly been testing a half-dozen self-driving cars around the San Francisco Bay Area, is just leasing a small number of Lexus RX450h SUVs from Hertz, with the idea of retrofitting them with self-driving test systems.

Either way, Jhonsa says both deals represent quite the contrast with what Tesla Inc. (TSLA) is trying to pull off. Elon Musk seems to want to go it all alone.
